- NASA and ESA formally announced Wednesday that Europe will develop a service module for at least one Orion mission based on the ATV cargo spacecraft. The service module for the EM-1 Orion mission, an uncrewed launch on the first Space Launch System (SLS) launch planned for 2017, will be built by Europe. The module will be based on the Automated Transfer Vehicle (ATV) cargo spacecraft Europe currently provides for taking cargo to the ISS, and this service module will take the place of ATV missions later this decade.
- The U.S. Air Force has delayed the launch date of its next Boeing Wideband Global Satcom (WGS) satellite owing to additional work needed to mitigate possible risk discovered in the last Delta IV rocket launch, during which the RL10B-2 upper stage engine malfunctioned.
- NASA’s Curiosity Mars rover is set to test its drill in the coming days on a rock that scientists believe may provide new information on the existence of water on the planet in its past. Scientists have selected a rock dubbed “John Klein”, after the late deputy project manager for the mission, as the likely first target for the rover’s drill.
- A massive wildfire swept through a major Australian astronomical observatory on Sunday, damaging some buildings but apparently sparing key telescopes there. The fast-moving fire hit the Siding Spring Observatory Sunday, part of a complex of fires in New South Wales, Australia that have broken out in extreme heat there. Authorities reported Monday that several buildings at the observatory, including lodges used by visiting astronomers and the visitors center, were destroyed. However, major telescopes there, including the 4-meter Anglo-Australian Telescope, appeared to have survived in good condition, although some instruments and equipment may be damaged.
- NASA’s Mars rover Curiosity is driving toward a flat rock with pale veins that may hold clues to a wet history on the Red Planet. If the rock meets rover engineers’ approval when Curiosity rolls up to it in coming days, it will become the first to be drilled for a sample during the Mars Science Laboratory mission.
- On Jan. 13, 2013, at 2:24 a.m. EST, the sun erupted with an Earth-directed coronal mass ejection or CME. Not to be confused with a solar flare, a CME is a solar phenomenon that can send solar particles into space and reach Earth one to three days later.
- NASA Deputy Administrator Lori Garver and Bigelow Aerospace Founder and President Robert Bigelow will discuss the Bigelow Expandable Activity Module program to the media on Wednesday, January 16, at Bigelow Aerospace facilities in Las Vegas.
- The Canadian Space Agency announced this week that it will press ahead with the country’s next-generation radar satellite imaging system, signing a contract with a Canadian firm to build the satellites. The RADARSAT Constellation system will feature three radar imaging satellites in polar orbits to provide shorter revisit times for radar imagery.
- New observations of the near Earth asteroid Apophis have ruled out any chance it will hit the Earth in 2036, NASA announced Thursday. The observations in 2011 and 2012, plus those carried out when the asteroid made a relatively close approach to the Earth on Wednesday, allowed scientists to refine the asteroid’s orbit. That new orbit effectively ruled out any chance that the asteroid, about 325 meters in diameter, will impact the Earth in 2036, with the odds of an impact now less than one in one million. Previously, there had been a very small chance of a 2036 impact, depending on the path the asteroid took when passing close to the Earth in April 2029.
- Officials with NASA and four companies involved with the space agency’s commercial crew development program said Wednesday that their efforts remain on schedule, with some companies planning crewed test flights as early as 2015. Boeing, Sierra Nevada Corporation, and SpaceX all said that that they are on track with development of their systems under Commercial Crew Integrated Capability (CCiCap) awards they received from NASA in August. Sierra Nevada said they plan to begin glide tests of their Dream Chaser vehicle from Edwards Air Force Base in California later this quarter, while SpaceX has a pad abort test of its Dragon launch escape system scheduled for December. A fourth company, Blue Origin, had a funded award in the previous round of the program and said they plan to see an unfunded extension to help guide continued work on their vehicle. NASA officials said a request for proposals for the next phase of the development effort will go out this fall, with plans to award multiple contracts by May 2014.
- Although not nearly as threatening as it was first perceived to be upon its discovery, the asteroid 99942 Apophis still has a very slight chance of impacting our planet on Friday, April 13, 2036. It will get closer to Earth this year, giving astronomers a chance to refine its trajectory for good and know whether we’re in trouble. And you can get a glimpse of it online tomorrow, courtesy of the Slooh Space Camera.
- 15 flights are scheduled to blast off from Florida’s Space Coast, including the first SpaceX missions from Cape Canaveral fully dedicated to putting commercial satellites into orbit.
- In a new and sharper hunt for the Universe’s most violent events, astronomers may have found two medium-sized galactic monsters. Launched in June, NASA’S NuSTAR (Nuclear Spectroscopic Array) X-ray observatory has discovered what may be two intermediate mass black holes in the spiral galaxy IC 342, some 7 million light-years from Earth.
- Small planets like our own are extremely abundant in the universe, according to new results presented here today at the 221st meeting of the American Astronomical Society.
- The discovery by astronomers at the University of California, Berkeley, and Clarion University in Pennsylvania of six likely comets around distant stars suggests that comets – dubbed “exocomets” – are just as common in other stellar systems with planets.
- The continuing success of NASA’s Kepler mission was highlighted on Monday, following the discovery of 461 new planet candidates – four of which are less than twice the size of Earth and orbit in their sun’s habitable zone. Scientists believe it’s just a matter of “when” a twin of our own planet is found by the spacecraft.
- Moon Express, one of the teams competing in the Google Lunar X PRIZE (GLXP), has reached an agreement where it will partner with Dynetics to acquire fellow GLXP team, the Rocket City Space Pioneers (RCSP). However, are not considered to be the team to beat by most experts—Astrobotic Technology currently holds that position.
- NASA-funded researchers analyzing a small meteorite that may be the first discovered from the Martian surface or crust have found it contains 10 times more water than other Martian meteorites from unknown origins. This new class of meteorite was found in 2011 in the Sahara Desert. Designated Northwest Africa (NWA) 7034, and nicknamed “Black Beauty,” it weighs approximately 11 ounces (320 grams). After more than a year of intensive study, a team of U.S. scientists determined the meteorite formed 2.1 billion years ago during the beginning of the most recent geologic period on Mars, known as the Amazonian.
- Comet Ison, due to loop around the Sun in December 2013, may or may not be “The Comet of the Century”. It is too early to tell.
- Astronomers using the Canada-France-Hawaii and W. M. Keck Observatory telescopes on the summit of Mauna Kea, Hawaii have been amazed to find a group of dwarf galaxies moving in unison in the vicinity of the Andromeda Galaxy. The structure of these small galaxies lies in a plane, analogous to the planets of the Solar System. Unexpectedly, they orbit the much larger Andromeda galaxy en masse, presenting a serious challenge to our ideas for the formation and evolution of all galaxies.
- SpaceX and Orbcomm Inc. have agreed to new contract terms for the launch of 18 data communications satellites beginning in mid-2013, according to a filing with a U.S. regulatory agency. The $42.6 million contract covers the launch of 18 second-generation Orbcomm satellites on two Falcon 9 rockets between the second quarter of 2013 and the second quarter of 2014.
- A study on the health effects of cosmic radiation has been published today in PLOS ONE. This new study is the first to establish a link between radiation experienced by space travelers and an increased chance of Alzheimer’s disease and dementia.
- IEEE Spectrum reviews Virgin Galactic and the plans for SpaceShipTwo in 2013.
- With all three Space Shuttle orbiters now tucked away inside their respective museums, the International Space Station (ISS) has completed its full year on-orbit in the post-Shuttle era, a year which has brought great successes for the orbital outpost. On the back of these successes in 2012, a promising 2013 awaits the station, with many new capabilities and technologies set to be demonstrated.

- NASA’s plan to use commercial spaceships to carry astronauts to orbit after the space shuttles retire is coming along nicely, the agency announced today. The four private companies awarded funding under NASA’s most recent round of Commercial Crew Development 2 (CCDev2) contracts have met all of their initial milestones so far, agency representatives said.
- A Minotaur rocket launched a small military satellite late Wednesday evening from Virginia. The Minotaur 1 rocket lifted off from the Mid-Atlantic Regional Spaceport at Wallops Island, Virginia, at 11:09 pm EDT (0309 GMT Thursday) and released the ORS-1 satellite into low Earth orbit about 12 minutes later.
- Space Security Policy: The US and EU recently released documents regarding space security. Should they come to an accord or should the US take the lead?
- Continuing Light Squared Issues: John Byrne heads the wireless and mobile infrastructure research group at IDC. He said the interference issue may continue to be a sticking point for LightSquared, even with the proposed solution. “At this point I think you have to assume that the deployment is on hold until those concerns are addressed to the satisfaction of the FCC and all of the congressmen and senators that are on the FCC on this issue,” he said.
- As military-launch costs soar, would-be competitors protest. Increase will be nearly 50 percent during the next four years.
- The White Sands Space Harbor, the landing site for the STS-3 in 1982, will be closing its doors after 35 years due to the end of the space shuttle program; the last launch is scheduled to take place in July.
- Following its replacement on Atlantis’ SSME-3 (Space Shuttle Main Engine), the new Main Fuel Valve (MFV) is undergoing a weekend of testing at Pad 39A, aimed at providing confidence the hardware will perform as required during the launch countdown. Meanwhile, inspections on ET-138′s stringers have been completed with no obvious issues reported.
- If skies are clear and all goes well Tuesday evening, observers throughout Maryland and much of the Mid-Atlantic region should be able to watch a big rocket launch from Virginia’s Wallops Island. The Air Force will attempt to launch a battlefield imaging satellite into orbit from the Mid-Atlantic Regional Spaceport. The ORS-1 satellite will ride atop a four-stage, solid-fuel Minotaur 1 rocket, the largest ever launched from the Delmarva peninsula.
- Asteroid 2011 MD will pass approximately 12,000 kilometers above the Earth’s surface at about 9:30 am EDT (1330 GMT) Monday, JPL reported Friday.
- NASA’s next Mars spacecraft arrived at Cape Canaveral this week in preparation for its launch later this year. The Mars Science Laboratory (MSL), also known as Curiosity, arrived at the Kennedy Space Center on Thursday on board a C-17 cargo aircraft, which flew the spacecraft from the Jet Propulsion Laboratory in California. MSL, the most advanced Mars rover built, is scheduled for launch late this year from Cape Canaveral on an Atlas 5 rocket.
- Betelgeuse, a red supergiant in the constellation of Orion, is one of the brightest stars in the night sky. It is also one of the biggest, being almost the size of the orbit of Jupiter — about four and half times the diameter of the Earth’s orbit. The VLT image shows the surrounding nebula, which is much bigger than the supergiant itself, stretching 60 billion kilometres away from the star’s surface — about 400 times the distance of the Earth from the Sun.
- Mark Kelly, the NASA astronaut who commanded the most recent shuttle mission and is married to congresswoman Gabrielle Giffords, announced on Tuesday his plans to retire. Kelly announced via social media that he would retire from both NASA and the US Navy on October 1.
- The “Deep Space Adventure” movie, lands July 8 at the Adler Planetarium, guiding earthbound visitors through an outer space journey that planetarium officials think is second only to actual space travel. 20 individual digital projectors for a screen resolution of more than 8,000-by-8,000 pixels will be replacing the 40-year-old Zeiss projector — made famous during a 2008 presidential debate when John McCain ripped a possible replacement as a “$3 million overhead projector”.
- Russia successfully launched their Progress M-11M resupply mission to the International Space Station at 7:38 AM Phoenix time (1438 UTC).
- Speaking at the 49th Paris Air Show in France, Vladimir Popovkin said that the Russian Space Agency (Roscosmos) will not produce a spaceship for tourists. Citing a full schedule of manned Soyuz and Progress re-supply missions to support the International Space Station as the reason for not proceeding at the moment, Popovkin did not rule out business in the future.
- China is preparing to launch the ZX-10 ZhongXing-10 – also designated ChinaSat-10, Sinosat-5 or Xinnuo-5 – domestic communications satellite on Monday (16:05-16:30 UTC) from the Xi Chang Satellite Launch Center, in Sichuan Province.
- Raffaello, more formally as the Multi-Purpose Logistics Module, is stuffed with a full year’s worth of necessities for the International Space Station. It will be loaded into shuttle Atlantis’ payload bay Monday to prepare for launch next month.
- NASA’s space probe Dawn is continuing its approach towards Vesta. The camera system on board is beginning to show the giant asteroid in more and more detail. The newest pictures taken on June 1st and processed by researchers at the Max Planck Institute for Solar System Research (MPS) in Germany already hint at the huge crater on Vesta’s southern hemisphere that is known from earlier observations. In addition, the new images show a dark feature close to the asteroid’s equator.

- After nearly three months in orbit about Mercury, MESSENGER’s payload is providing a wealth of new information about the planet closest to the Sun, as well as a few surprises.
- Comet Hartley 2’s hyperactive state, as studied by NASA’s EPOXI mission, is detailed in a new paper published in this week’s issue of the journal Science. “Hartley 2 is a hyperactive little comet, spewing out more water than most other comets its size,” said Mike A’Hearn, principal investigator of EPOXI from the University of Maryland, College Park. “When warmed by the sun, dry ice — frozen carbon dioxide — deep in the comet’s body turns to gas jetting off the comet and dragging water ice with it.”
- The Sun may be entering an extended period of relatively quiet activity, a development that has implications for space exploration and possibly the Earth’s climate. Scientists said at a meeting Tuesday of the American Astronomical Society’s Solar Physics Division in New Mexico that evidence was mounting that the Sun’s activity would diminish, perhaps for an extended period. Solar scientists have not detected a zonal flow associated with the onset of a new cycle of solar activity, and others found a long-term weakening trend in sunspots.

That satellite will be launched by SpaceX on a Falcon 9 rocket in the second quarter of 2013.
- Test results compiled by the National Executive Committee for Space-Based Positioning, Navigation and Timing indicate the 4G network under development from LightSquared interferes with GPS signals, darkening the network’s prospects.
- The Japan Aerospace Exploration Agency (JAXA)’s Hayabusa space probe has been officially recognized by Guinness World Records, adding yet another feather to the project’s cap after the accolades that have poured in from the scientific community over the past year. Recognition by Guinness World Records “will help spread knowledge of the Hayabusa probe’s achievements among the Japanese people, so I’m very happy,” said JAXA’s Hayabusa project manager Junichiro Kawaguchi.
- Post flight processing continues on the Endeavour space shuttle.
- NASA’s Dawn mission to the doughnut-shaped asteroid belt between Mars and Jupiter, which launched in September 2007, is now approaching Vesta, a protoplanet that is currently some 143 million miles from Earth.
- Three years before its arrival the camera system on board the space probe Rosetta renders the first images of its destination. Comet Churyumov-Gerasimenko is the 2014 target.
- The European Space Agency should formally approve this summer the construction of an Italian-led demonstrator that will launch into space on a rocket, fly back to Earth like an airplane and parachute into the Pacific Ocean. The Intermediate Experimental Vehicle is on track to blast off on a Vega rocket in late 2013, speed around the Earth at a peak altitude of nearly 300 miles, then drop from space and fly back to Earth with the help of aerodynamic flaps and a parachute.

- The space shuttle Atlantis arrived at the launch pad early Wednesday as preparations for the final mission of the space shuttle era continue. Atlantis arrived at launch pad 39A at 12:29 AM Phoenix time (0729 GMT) Wednesday, just under seven hours after leaving the Vehicle Assembly Building and less than an hour after the shuttle Endeavour landed at the Shuttle Landing Facility several miles away. Atlantis is scheduled for launch on STS-135, the final shuttle mission, on 8 July 2011.
- Atlantis (STS-135) was soaked by thunderstorms and is undergoing checks following lightning storm
- A drive of 482 feet (146.8 meters) on June 1, 2011, took NASA’s Mars Exploration Rover Opportunity past 30 kilometers (18.64 miles) in total odometry during 88 months of driving on Mars. That’s 50 times the distance originally planned for the mission and more than 12 times the distance racehorses will run next week at the Belmont Stakes.
- In two separate reports, astronomers reveal ancient globular clusters to be breeding much younger blue-straggler members, and a relatively young open cluster hosting an aging stellar population, calling into question theories of stellar evolution.

- Discovery is scheduled to begin her journey back out to Pad 39A with her modified External Tank (ET-137) at 6:00 PM Phoenix time (0100 UTC Tuesday) on Monday evening, following an issue-free installation of radius blocks on most of its intertank stringers. With a high-level of confidence in the mitigation of further cracks on the stringers during loading and launch, managers have called for the same modifications to take place on STS-134′s ET-122.
- The Russian cargo spacecraft Progress M-09M docked with the International Space Station (ISS) on Sunday.
- The Runaway Star. Traveling at a breakneck speed of 87,000 kilometers per hour (or 24 kilometers per second), the massive Zeta Ophiuchi probably used to have an even larger binary partner that exploded as a supernova. So, like a hammer thrower spinning quickly at the Olympic Games, the blue supergiant star was treated like the hammer, released from the gravitational embrace of its exploding sibling in an instant. At the moment of detonation, it’s orbital momentum shot it off into space at high speed.
- Hot on the heels of JAXA’s HTV-2 arrival at the International Space Station (ISS), Russia’s Progress M-09M/41P spacecraft has lifted off from the Baikonur Cosmodrome in Kazakhstan on Friday morning at 1:31 AM GMT. Docking to the ISS at the Docking Compartment-1 (DC-1) Pirs Nadir port, recently vacated by Progress M-08M/40P, will occur two days later on Sunday 30th January at 2:40 AM GMT.
- The fuel and most of the cargo are loaded and ATV has been hoisted to the top of Ariane 5 as teams on four continents prepare for the 15 February launch of Johannes Kepler from Europe’s Spaceport in Kourou, French Guiana.
- After less than a week in space, Japan’s HTV-2 spacecraft was successfully grappled by the ISS crew via the SSRMS (Space Station Remote Manipulator System), ahead of berthing to Node-2 Nadir – which was completed at 07:51 AM Phoenix time (14:51 UTC). Over the coming days, the ISS crew will remove external payloads from HTV-2 before moving the spacecraft to a temporary berthing location on Node-2 Zenith ahead of the arrival of STS-133 in late-February.
- The first image of comet Tempel 1 taken by NASA’s Stardust spacecraft is a composite made from observations on Jan. 18 and 19, 2011. On Valentine’s Day (Feb. 14 in U.S. time zones), Stardust will fly within about 200 kilometers (124 miles) of the comet’s nucleus
- Astronomers announced Wednesday the discovery of the most distant galaxy yet observed, an object that dates back to the first half-billion years of the universe. The object, designated UDFj-39546284, is a compact galaxy of blue stars with a redshift of approximately 10, which dates the galaxy to just 480 million years after the Big Bang. Astronomers discovered the galaxy in Hubble Ultra Deep Field – Infrared data collected by the Hubble Space Telescope’s Wide Field Camera 3 in 2009 and 2010.
- The European Space Agency (ESA) has released images of Phobos from the Mars Express at an altitude of 100 km. The images are from the High Resolution Stereo Camera (HRSC) science team and show a 3D view of the moon and the proposed landing site of the Phobos-Grunt mission.
- A Russian Progress M-08M cargo spacecraft undocked from the ISS early on Monday, clearing a port for a new Progress scheduled for launch on Friday 28 January. The Progress spacecraft undocked from the Pirs module at just after 5:40 PM Phoenix time on Sunday (0040 GMT Monday) and deorbited over the south Pacific five and a half hours later.
- A group of United Space Alliance (USA) and Michoud Assembly Facility (MAF) technicians and engineers are heading into the final few days of work on modifying the stringers on Discovery’s External Tank (ET-137). With the root cause evaluations and subsequent modifications ensuring there is “no uncertainty” on all flight tanks, STS-133 remains on track for rollout to Pad 39A next Monday. All indications are that 24 February will be the start of the launch window.
- Amateur satellite observers have confirmed that the Delta 4-Heavy launched last Thursday carried a Keyhole type replacement spy satellite. The newest satellite joins the two primary Keyholes in space today, having launched in 2001 and 2005 from Vandenberg aboard Titan 4 rockets, plus an older one deployed in 1996 that’s still running in a backup role. The Delta 4-Heavy flight targeted the orbit of the 2001 satellite, apparently to assume the lead observation duties from the aging craft that’s now achieved the record for the longest prime mission duration.
- A team of scientists from several organizations will begin tests this spring on a space-based power generation technology using satellites, it was learned Saturday. The planned test will attempt to convert a strong electric current into microwaves and transmit them 10 meters away in a simulated outer space environment at Kyoto University. A successful test would likely accelerate the goal of putting a space-based power generation system into practical use by 2025.
- The Japanese Aerospace Exploration Agency (JAXA) successfully launched its large HTV-2 (“Kounotori” – White Swan) resupply mission to the International Space Station.
- JAXA confirmed that the planned second burn and re-entry of the second stage of the H-IIB rocket was successful. This followed the launch of the Kounotori resupply spacecraft to the International Space Station.
- Two Russian cosmonauts, Dmitry Kondratyev and Oleg Skripochka, spent five and a half hours in space working on the International Space Station late on Friday. The cosmonauts installed a high-speed data transmission block on the Russian service module “Zvezda,” disabled and dismantled a plasma injector equipment, and installed a TV camera on the MIM mini-research module of the Russian segment of the ISS.
- Aviation Week discusses the plans by SpaceX to eventually carry crew to the International Space Station. “Space Exploration Technologies (SpaceX) says it will launch its Falcon 9 rocket at least 17 more times before it is ready to fly humans, with nine of those flights carrying the Dragon capsule it is developing for cargo missions to the International Space Station.”
- Discovery.com “roasts” the Australian story about Betalgeuse going super nova in 2012. And Phil Plait gives us the straight scoop. Meanwhile, once interesting Huffington Post makes a complete hash of the story.
- The launch of the JAXA resupply mission HTV-2 to the ISS is set for 10:37 PM Phoenix time tonight (5:37 UTC 22 February).
- NASA selected astronaut Steve Bowen as a mission specialist on STS-133, the next space shuttle mission planned for launch on Feb. 24. Bowen replaces astronaut Tim Kopra, who was injured in a bicycle accident over the weekend. The agency will hold a media teleconference at 3:30 p.m. CST on Wednesday, Jan. 19, to discuss the change in crew personnel.
- Russia launched a Zenit / Fregat-SB rocket carrying an Elektra-L satellite at 12:29:01 UTC.
- The United States launched a Delta IV Heavy carrying the NRO L-49 spy satellite from Vandenberg Air Force base in California a little after 2:00 PM Phoenix time today.
- NASA’s Stardust-NExT spacecraft is nearing a celestial date with comet Tempel 1 at approximately 11:37 p.m. EST, on Feb. 14. The mission will allow scientists for the first time to look for changes on a comet’s surface that occurred following an orbit around the sun.
- The launch of the H-IIB Launch Vehicle No. 2 (H-IIB F2) with the KOUNOTORI2 (HTV2, a cargo transporter to the International Space Station) onboard has been rescheduled as clouds including a freezing layer that exceeds the restrictions for suitable weather are forecast to be generated at around the scheduled launch time on January 20, 2011 (Japan Standard Time.) No Earlier Than (NET) 22 January.
- A Delta 4-Heavy rocket, made by United Launch Alliance, and carrying a massive spy satellite like the ones the Titans used to deploy before those rockets were retired from service in 2005, is scheduled for liftoff Thursday at 1:08 p.m. PST (4:08 p.m. EST; 2108 GMT) from Space Launch Complex 6 at Vandenberg Air Force Base.
- Technology Review has an update on the status of Sierra Nevada’s Dream Chaser, descendant of NASA’s HL-20 manned space plane program from the 1970’s.
- WikiLeaks documents published by a Norwegian newspaper have cost the CEO of OHB-Technology, a German satellite company, his job. Berry Smutny reportedly said “I think Galileo is a stupid idea that primarily serves French interests.” OHB-Technology company has the contract to build the first 14 satellites.
- A recent storm of small “suicide” comets that pelted the sun could herald the coming a much bigger icy visitor.
- Shuttle Discovery is aiming to roll back out to Pad 39A on February 1, following what will be the completion of numerous “radius block” modifications to the circumference of her External Tank (ET-137). NASA managers are also evaluating impacts to crew training – and potentially the launch date – following the injury sustained by STS-133′s Tim Kopra during a biking accident.
- The Universe in High Definition – When it comes to digital cameras, people really care about their megapixels. The Sloan Digital Sky Survey has them all beat with a newly released TERApixel mosaic of the sky
- The European Space Agency (ESA) has new commentary on the Johannes Kepler ATV-2 resupply vessel scheduled for launch to the International Space Station on 15 February 2011. It will be the heaviest load ever lofted into space by the Ariane 5 rocket, making the 200th flight of the European launcher even more spectacular.
- International Space Station Program (ISSP) managers at NASA’s Johnson Space Center (JSC) in Houston held a two-day meeting this week to discuss the prospect of adding a Bigelow Aerospace inflatable module to the ISS.

- The Planck spacecraft, which is designed to study the faint afterglow of the Big Bang, has discovered a rash of new galaxy clusters, along with details of our own Milky Way.
- NASA announced Thursday that astronaut Rick Sturckow will serve as a backup commander for the STS-134 space shuttle mission to facilitate continued training for the crew and support teams during STS-134 Commander Mark Kelly’s absence. Kelly’s wife, Congresswoman Gabrielle Giffords, was critically wounded in a shooting on Jan. 8 in Tucson, Arizona. Kelly remains commander of the mission, which is targeted for launch on April 19 from NASA’s Kennedy Space Center in Florida.
- Intelsat has said the former zombie satellite Galaxy 15 is again under full control and will return to commercial operation. During a webcast, Tobias Nassif, VP of satellite operations and engineering, said Intelsat has re-established full functionality over Galaxy 15. Galaxy 15 is currently positioned at 93 degrees West, where it will undergo additional testing and then be moved to either 133 degrees West or 129 degrees West, depending on demand for services. Intelsat expects to complete testing by January 31.
- A preliminary NASA report, outlining plans for developing a Space Launch System (SLS) in response to the NASA Authorization Act of 2010, has put its weight behind a Inline Shuttle Derived (SD) Heavy Lift Launch Vehicle (HLV). However, the report to lawmakers complained it would not be able to build the vehicle based on the funding and schedule requirements.
- NASA’s Kepler spacecraft, an observatory originally designed to hunt for alien planets, has stumbled upon an intriguing discovery: a set of triplet stars circling a massive stellar parent.
- Aviation Week comments on the fact that Space shuttle officials have concluded that a combination of weaker-than-expected materials and subtle assembly issues led to the external tank (ET) cracks that have stalled the launches of Discovery and Endeavour on NASA’s last two scheduled shuttle missions.
- A newly discovered planet beyond the solar system is not only the smallest extrasolar planet yet found but also the first confirmed to be made entirely of solid material. Discovered by NASA’s Kepler spacecraft and dubbed Kepler-10b, the body has a diameter only 40 percent larger than Earth’s.
- The Hubble Space Telescope has zoomed in on the mysterious green cloud of gas known as Hanny’s Voorwerp (after the Dutch school teacher Hanny van Arkel who discovered it using the citizen science project Galaxy Zoo) to reveal a zone of star formation.
- Using the world’s largest telescopes in Hawaii and Chile, the researchers have used Quasar Absorption Line Spectroscopy to identify gas clouds called ‘damped Lyman alpha systems’ (DLAs). Among the thousands of DLAs known, the team have succeeded in finding a rare cloud released from a star very early in the history of the universe. The gas cloud was released by the exploding star around 13 billion years ago, one of the earliest stars in the universe.
- By the end of the decade, five new telescopes will be completed which are each hugely more powerful than any before them and may answer vital questions about our universe. Among the objects that astronomers hope to study will be the first stars and galaxies that formed after the Big Bang – the birth of the universe 13.7 billion years ago. It is also hoped the new super-telescopes will be able to spot Earth-like planets in orbit round other stars and give early warnings of asteroids or meteorites heading on a collision course with Earth.
- Following the further delay of the STS-133/ULF-5 mission into late February, International Space Station (ISS) Program Managers are readjusting the mission plans for Europe’s Automated Transfer Vehicle-2 (ATV-2) “Johannes Kepler” and Japan’s H-II Transfer Vehicle-2 (HTV-2) “Kounotori”. Both vehicles will be present at the ISS during the STS-133 mission, which should provide for some stunning views during Discovery’s flyaround post-undocking.
- Thursday’s Program Requirements Control Board (PRCB) meeting overviewed the status of Discovery’s External Tank (ET-137), with recommendations made to install radius blocks on over 100 stringers. A new launch date will be entered as a Change Request (CR) next week, based on negotiations with the ISS on the ability to achieve either a February 24 or 27 NET (No Earlier Than) target.
- NASA released its annual SpinOff report at the end of December.
- The root cause of the cracked stringers on STS-133′s External Tank (ET-137) may have been found, following the investigation team’s findings that the material used for the tank’s intertank support beams was found to be “mottled”, when compared to standard material. While the work on the 34 stringers is already approved, Thursday’s Program Requirements Control Board (PRCB) will discuss an option to install radius blocks on all 108 remaining stringers, which in turn would slip STS-133 out of the early February launch window.
- Aviation Week reports on the newly ordered repairs to the external tank of the space shuttle Discovery. Launch is still slated for 3-10 February 2011.
- Kathryn Aurora Gray, a precocious 10-year-old amateur astronomer from Fredericton, New Brunswick in Canada, has discovered a supernova explosion in a galaxy, called UGC 3378, within the faint constellation of Camelopardalis. The galaxy is approximately 240 million light-years away.
- In 2011 a strong display of Quadrantid meteors is likely for Europe and points east to central Asia. Maximum activity is expected at around 0100 GMT on Tuesday, Jan. 4 when the radiant of this shower – from where the meteors appear to emanate – is ascending the dark northeastern sky. With no moonlight to interfere, this might turn out to be one of the best meteor displays of the year. Morning twilight will not interfere until about 6 a.m. local time. What about for North America? At the time the shower is reaching its peak, it will be Monday evening, Jan. 3 on the other side of the Atlantic; 8 p.m. EST in the East and 5 p.m. PST (still twilight) in the West. The radiant will be positioned low near the north-northwest horizon.
- Long past their 90 day warranties, The Martian Rovers are approaching seven Earth years on the surface of Mars. Spirit landed on Mars on 4 January 2004. Its twin, Opportunity, hit the planet’s red dirt three weeks later, on 25 January.
- An Indian rocket that tumbled out of control and was destroyed a minute after liftoff last month failed because of a snapped data cable, investigators said Friday. The Geosynchronous Satellite Launch Vehicle (GSLV) lifted off normally on December 25 but started losing attitude control 47.8 seconds later; the rocket broke up at T+53.8 seconds and was destroyed by range safety at T+64 seconds. An initial investigation, chaired by former ISRO chairman G. Madhavan Nair, concluded that the primary cause of the failure is the “untimely and inadvertent” snapping of a group of 10 connectors at the base of the upper stage linking the rocket’s avionics, located in the upper stage, with the rocket’s lower stages. The snapped cables prevented commands from reaching the first stage’s electronics, causing the rocket to lose control. Why the cables snapped remains unknown.
- In a controversial move, Brazil will pay more than €250 million over a decade to become a member of the European Southern Observatory (ESO). The agreement is part of a bid by Brazil’s government to lift the quality of domestic science by joining big international projects. Brazil has also been negotiating entry into Europe’s CERN particle accelerator.

- The European Space Agency has announced that two of 31 mission proposals have been chosen for additional development funding. The CarbonSat mission would quantify and monitor the distribution of two of the most important greenhouse gases in the atmosphere, also released through human activity: carbon dioxide and methane. Data from the mission would lead to a better understanding of the sources and sinks of these two gases and how they are linked to climate change. The FLEX mission aims to provide global maps of vegetation fluorescence, which can be converted into an indicator of photosynthetic activity. These data would improve our understanding of how much carbon is stored in plants and their role in the carbon and water cycles.

10 November 2010
- A new study from Galaxy Zoo’s second crowd-sourced scientific effort, buoys the idea that galaxies with central bars somehow encourage the formation of big, blue and short-lived stars, and funnel gas and dust to supermassive black holes lurking at their cores. In the process, bars may quickly consume star-making materials to leave behind only a “dead” galaxy of red and fading stars.
- The NASA Hubble Space Telescope has returned an image of a wandering cloud of gas and dust from an area of the well-known Pleiades star cluster. Starlight from Merope is slowly destroying the small nebula.
9 November 2010
- NASA’s Fermi Gamma-ray Space Telescope has unveiled a previously unseen structure centered in the Milky Way. The feature spans 50,000 light-years and may be the remnant of an eruption from a supersized black hole at the center of our galaxy. “What we see are two gamma-ray-emitting bubbles that extend 25,000 light-years north and south of the galactic center,” said Doug Finkbeiner, an astronomer at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., who first recognized the feature. “We don’t fully understand their nature or origin.”
- Engineers at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., expect the Cassini spacecraft will resume normal operations on 24 November, after the spacecraft went into safe mode on 2 November.
- NASA hopes to lay the groundwork over the next six months for developing an affordable heavy-lift launch vehicle with $7.5 million in study contracts it plans to spread across 13 U.S. companies. The study contracts, announced Nov. 8, are NASA’s initial response to the 2010 NASA Authorization Act, which requires the agency to begin work this year on a vehicle capable of lifting at least 70 metric tons to low Earth orbit by 2016.
8 November 2010
- China unveiled an image of the Bay of Rainbows taken by the lunar orbiter Chang’e-2 from a designed altitude of 18.7 kilometers. The image was taken on 28 October, and covers the area that China plans to land its next mission.
- A new theoretical model of Solar coronal mass ejections (CMEs) will be presented at the 52nd Annual Meeting of the APS Plasma Physics Division. The Sun sporadically expels trillions of tons of million-degree hydrogen gas during a CME. Such clouds are enormous in size (spanning millions of miles) and are made up of magnetized plasma gases, so hot that hydrogen atoms are ionized. CMEs are rapidly accelerated by magnetic forces to speeds of hundreds of kilometers per second to upwards of 2,000 kilometers per second in several tens of minutes. CMEs are closely related to solar flares and, when they impinge on the Earth, can trigger spectacular auroral displays. They also induce strong electric currents in the Earth’s plasma atmosphere (i.e., the magnetosphere and ionosphere), leading to outages in telecommunications and GPS systems and even the collapse of electric power grids if the disturbances are very severe.

- Super Earths may be hostile to life, suggests a New Scientist article. “Rocky planets a few times heavier than Earth that we thought might be life-friendly may lack one vital feature: a protective magnetic field. Planets are thought to owe their magnetic fields to an iron core that is at least partly molten. But a simulation of super-Earths between a few times and 10 times Earth’s mass suggests that high pressures will keep the core solid, according to Guillaume Morard of the Institute of Mineralogy and Physics of Condensed Matter in Paris, France, and his team (arxiv.org/1010.5133).”

- Discovery was making her first real attempt to launch on Friday, as the loading of her External Tank (ET-137) picked up following approval by the Mission Management Team (MMT). Tanking had been nominal until a leak was detected on the Ground Umbilical Carrier Plate (GUCP) – causing managers to carry out testing prior to detanking – ultimately leading to a delay to November 30.
- At 8:20 PM Phoenix time, the ULA team successfully launched the fourth COSMO-SkyMed satellite for Boeing, the Italian Space Agency, Ministry of Defence and Thales Alenia Space. The ULA Delta II 7420-10 configuration vehicle used a ULA first stage booster powered by a Pratt & Whitney Rocketdyne RS-27A main engine and four Alliant Techsystems (ATK) strap-on solid rocket boosters. An Aerojet AJ10-118K engine powered the second stage. The payload was encased by a 10-foot-diameter composite payload fairing. COSMO-SkyMed 4 is the final satellite in the initial constellation for this system. Each of the four satellites is equipped with a high-resolution Synthetic Aperture Radar operating in X-band.
