- 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 announced that “NASA’s Gravity Recovery And Interior Laboratory (GRAIL)-A spacecraft successfully completed its planned main engine burn at 2 p.m. PST (5 p.m. EST) today. As of 3 p.m. PST (6 p.m. EST), GRAIL-A is in an orbit of 56 miles by 5,197 miles (90 kilometers by 8,363 kilometers) around the moon that takes approximately 11.5 hours to complete.”
- Two NASA spacecraft launched in December are ready to enter lunar orbit this weekend, project officials confirmed this week. The twin Gravity Recovery And Interior Laboratory (GRAIL) spacecraft will fire thrusters to go into orbit around the Moon, with GRAIL-A arriving at 2:21 PM Phoenix time (2121 UTC) Saturday and GRAIL-B at 3:05 PM Phoenix time (2205 UTC) Sunday.
- The Chinese government published on Thursday a white paper describing that country’s five-year plan for spaceflight, including development of new launch vehicles and a continued emphasis on space stations and lunar exploration.
- Less than a week after one Soyuz rocket failed, another successfully placed six Globalstar satellites into orbit on Wednesday. The Soyuz 2-1a rocket lifted off from the Baikonur Cosmodrome in Kazakhstan at 12:09 pm EST (1709 GMT, 11:09 pm local time) Wednesday and released six Globalstar satellites into low Earth orbits an hour and a half later.
- China turned on this week the first phase of its own satellite navigation system that will eventually compete with GPS and other such systems. The Beidou, or Compass, system started providing navigation services Tuesday for users in China and “surrounding areas”, although elements of the system have been in orbit for a decade.
- Comet Lovejoy became visible again to the naked eye in the Southern Hemisphere last week—and continued to streak across predawn skies through the holiday weekend. Lovejoy lost its original tail as it skimmed the sun’s surface, the comet “reappeared almost like a point and redeveloped a tail on the way out, which I thought was quite amazing,” said astronomer Lovejoy
- The launch of a European communications satellite scheduled for this week has been delayed until mid-January because of a problem discovered Monday with its Proton rocket. The Proton-M rocket was scheduled to launch just after midnight local time Tuesday from Baikonur, carrying the SES-4 satellite for SES of Luxembourg. However, during pre-launch preparations Monday technicians discovered a problem with the avionics of the Proton’s Briz-M upper stage. The rocket will be rolled back to complete the repairs, and International Launch Services said in a statement Monday that those repairs would postpone the launch by about 25 days.
- NASASPaceFlight discusses the Soyuz failure with Meridian, and the redressing Russia’s internal woes.
- A Soyuz spacecraft carrying three people docked with the International Space Station Friday morning, restoring the station to normal six-person operations. The Soyuz TMA-03M spacecraft docked with the station’s Rassvet module at 10:19 am EST (1519 GMT) Friday, two days after launch from Baikonur. On board the Soyuz are the three new members of the Expedition 30 crew, Don Pettit of NASA, Oleg Kononenko of Roscosmos, and Andre Kuipers of ESA.
- A Russian communications satellite failed to reach orbit Friday after the failure of the upper stage of its Soyuz rocket, the latest in a string of Russian launch failures. The Soyuz 2-1b rocket lifted off from the Plesetsk Cosmodrome in northern Russia at 7:08 am EST (1208 GMT, 4:08 pm Moscow time) carrying a Meridian communications satellite. While the launch initially appeared to go well, Russian officials later said the satellite failed to reach orbit and instead crashed in Siberia. Initial reports indicated a problem with the rocket’s third stage. The launch failure is the fifth in just over a year for Russia, including the loss of a Progress cargo spacecraft
- An astronaut living in space has captured an unprecedented view of a comet from orbit in a jaw-dropping set of photos taken over a nighttime Earth. Comet Lovejoy is visible near Earth’s horizon in this nighttime image photographed by NASA astronaut Dan Burbank, Expedition 30 commander, onboard the International Space Station on Dec. 21, 2011. The amazing images show comet Lovejoy, which survived a trip through the sun’s atmosphere last week.
- NASA astronaut Don Pettit, Russian cosmonaut Oleg Kononenko, and Dutch astronaut Andre Kuipers, part of the European Space Agency (ESA), lifted off atop the Russian Soyuz TMA-03M spacecraft from Baikonur Cosmodrome in Kazakhstan at 8:16 a.m. EST (1316 GMT) on a trip to the International Space Station.
- On Wednesday, the space agency released new images of the hummocky surface of asteroid Vesta as Dawn circled from an average altitude of 130 miles (209 kilometers) above the surface, the closest it’ll get.
- Russian Soyuz TMA-03M spacecraft set for launch to International Space Station
- Two planets, dubbed Kepler-20e and 20f, are the smallest planets found to date by the Kepler spacecraft observatory. They have diameters of 6,900 miles and 8,200 miles — 0.87 times Earth (slightly smaller than Venus) and 1.03 times Earth. These worlds are expected to have rocky compositions, so their masses should be less than 1.7 and 3 times Earth’s. Both worlds circle Kepler-20: a G8 yellow star a little less hot than the Sun and located 950 light-years from Earth
- Flying on its last bit of fuel, NASA’s Deep Impact probe is carefully reshaping its course toward a potentially hazardous near-Earth asteroid in hopes the spacecraft can survey the body in January 2020.
- A Soyuz rocket lifted off from Kourou Friday night, placing six French and Chilean satellites into orbit. The Soyuz STA rocket lifted off from Kourou, French Guiana, at 9:03 pm EST Friday (11:03 pm local time Friday, 0203 GMT Saturday) and placed its payload of six satellites into Sun-synchronous orbit over the next three and a half hours.
- Citing uncertain budgets, NASA announced Thursday it was switching from a fixed-price contract back to Space Act Agreements (SAAs) for the next phase of its commercial crew development program. NASA had planned to issue an RFP next week for the “Integrated Design Phase” of the program, designed to mature several potential vehicles to the critical design review level of development. However, NASA officials said a “dynamic budget environment”, including uncertainty about how much money the program will get in future years, led it to go back to the more flexible SAAs used in the first two phases of the effort. A formal request for proposals for this program will go out in early 2012. The overall commercial crew program seeks to support the commercial development of spacecraft to transport astronauts to and from the ISS, as well as for other commercial applications. The program received less than half of the requested funding for 2012, and as a result NASA officials say they don’t expect vehicles to be ready to enter service until 2017.
- A cloud of gas is being pulled closer to the supermassive black hole* lurking in the center of our galaxy, 27,000 light-years away. This unprecedented discovery is being monitored by an international team of scientists using the European Southern Observatory’s Very Large Telescope (VLT). The cool cloud, composed mainly of hydrogen and helium, with a mass three-times that of Earth, has been picking up speed, and by 2013, astronomers will hopefully see some fireworks. By then, the first wisps of gas should be sucked into the black hole’s event horizon causing the black hole to flare brightly.
- Boris Chertok, supporter of the founder of cosmonautics Sergei Korolyov, passed away in Moscow on Wednesday. “The last of the Mohicans” in Russian cosmonautics, Chertok was one of the first to make an endeavor to conquer space. He passed away barely 2.5 months before his hundredth birthday. He was closely involved in putting the world’s first satellite in orbit on Oct. 4, 1957, and preparing the first human flight to space by Yuri Gagarin on April, 12 1961.
- The ill-fated Phobos-Grunt probe that got stuck in the orbit after an unsuccessful launch will fall to Earth on January 11, probably affecting four continents, the US Strategic Command shared its latest forecast. The current orbit of the vehicle suggests that it could collide with the surface on a vast part of the globe, from latitude 51.4°N to latitude 51.4°S. anywhere in Africa, Australia, Japan, North America or southern part of Western Europe, but definitely not on the larger part of the Russian territory.
- A Japanese rocket launched the latest in a series of reconnaissance satellites for the country on Monday. The H-2A lifted off from the Tanegashima Space Center in Japan at 8:21 pm EST Sunday (0121 GMT, 10:21 am local time Monday) and placed an Information Gathering Satellite (IGS) into orbit. Japanese officials released few details about the mission, although this IGS is believed to have a radar imaging payload.
- Funded as a Paul G. Allen project under the banner of Stratolaunch, Burt Rutan is taking his space tourism concept a step further, by developing an air-launch system for payloads in the 10,000lbm class into Low Earth Orbit (LEO). The system will be able to launch from several possible operational sites and eventually aims to provide crewed services.
- NASA’s Cassini spacecraft successfully completed its closest-ever pass over Saturn’s moon Dione on Monday, Dec. 12, slaloming its way through the Saturn system on its way to tomorrow’s close flyby of Titan. Cassini is expected to glide about 2,200 miles (3,600 kilometers) over the Titan surface on Dec. 13.
- NASA’s Dawn spacecraft successfully maneuvered into its closest orbit around the giant asteroid Vesta today, beginning a new phase of science observations. The spacecraft is now circling Vesta at an altitude averaging about 130 miles (210 kilometers) in the phase of the mission known as low altitude mapping orbit.
- ESA astronaut André Kuipers is now officially ready for liftoff on 21 December: he and his crewmates have passed their final exams and left for the launch site yesterday. Every crew destined for the International Space Station must endure two days of final exams in the simulators at Star City near Moscow before they are cleared for flight.
- A Proton-M carrier rocket with two telecommunications satellites onboard blasted off from the Baikonur space center in Kazakhstan on Sunday. The separation of Russia’s Luch-5A spacecraft is scheduled for 20:11 UTC Sunday, while Israel’s Amos-5 satellite will separate at 20.52 UTC.
- NASA announced Friday that the next commercial cargo demonstration mission to the ISS by SpaceX will launch on February 7. On that date SpaceX plans to launch its Dragon cargo spacecraft on a Falcon 9 rocket from Cape Canaveral. The spacecraft will approach the station and perform a flyby at a distance of two miles to demonstrate its ability to safely operate close to the station. If successful, the spacecraft will then more closely approach the station, whose robotic arm will grapple the spacecraft and berth it to the station’s Harmony node.
- About 3,700 years ago, people on Earth would have seen a brand-new bright star in the sky. It slowly dimmed out of sight and was eventually forgotten, until modern astronomers later found its remains, called Puppis A. In this new image from NASA’s Wide-field Infrared Survey Explorer (WISE), Puppis A looks less like the remains of a supernova explosion and more like a red rose.
- Russia’s troubled Phobos-Grunt spacecraft will fall back to Earth on January 9, the United States Strategic Command said.
- NASA announced that the Mars rover Opportunity has found veins of Gypsum (calcium sulfate) on the crater wall of Endeavour Crater. “This tells a slam-dunk story that water flowed through underground fractures in the rock,” said Steve Squyres of Cornell University, principal investigator for Opportunity. “This stuff is a fairly pure chemical deposit that formed in place right where we see it.”
- The Large Hadron Collider at CERN apparently has a signal for the Higgs boson. Both the ATLAS and CMS experiments are independently seeing a Higgs signal, and the predicted mass of the particle agrees with the experimental results. The Higgs appears to have a mass of 125 GeV (gigaelectronvolts), and the signal has a 4.2 sigma, just short of the 5.0 value deemed to be conclusive.
- New Mexico Spaceport Authority (NMSA) officials announced Tuesday a successful launch over the weekend of an advanced sounding rocket designed and built by Armadillo Aerospace. The launch took place from Spaceport America’s vertical launch complex on Sunday.
- Astronomers announced Monday the first discovery in data from NASA’s Kepler mission of a planet in the habitable zone of a Sun-like star. The planet, designated Kepler-22b, is about 2.4 times the radius of the Earth and would have an average surface temperature of 22 degrees Celsius, but astronomers said they did not have information about the planet’s mass or potential composition, thus making them unable to say just how much this planet may be like the Earth.
- SpaceX’s Dragon demonstration flight to the International Space Station (ISS) is understood to be moving into the February/March timeframe, while approval for the combination of the C2/C3 (D2/D3) missions – which would result in Dragon arriving at the orbital outpost – is still pending official approval from NASA and the ISS partners.
- New views of giant asteroid Vesta revealed
- Despite a small period of time where it was hoped communications and commanding might be established with the stricken Fobos-Grunt spacecraft, it now appears the Russian probe’s future is one which will see it head towards a fiery end, as its orbit continues decay over time. The likely scenario now points to a destructive re-entry sometime in January.
- The Baikonur launch site is being prepared for the takeoff of the Soyuz TMA-03M manned spacecraft. The Soyuz-FG rocket and spacecraft will be positioned on 19 December, with take off at 7:17 AM Phoenix time (1417 UTC – 5:17 PM Moscow time) on 21 December. The spacecraft will carry the 30TH/31ST crew to the International Space Station (ISS), and their stay will last for six months. Oleg Kononenko, Andrei Kuipers and Donald Pettit are the crew members.
- NASA’s New Horizons mission reached a special milestone today on its way to reconnoiter the Pluto system, coming closer to Pluto than any other spacecraft. It’s taken New Horizons 2,143 days of high-speed flight, covering more than a million kilometers per day for nearly six years, to break the closest-approach mark set by NASA’s Voyager 1 in January 1986.
- NASA’s Cassini spacecraft captured unprecedented radar imagery of Saturn’s icy moon Enceladus last month, uncovering new details of the moon’s highly reflective frozen surface.
- Following the launch by the Atlas V 541 and two precise burns by the Centaur second stage, Curiosity was placed in such an accurate orbit to Mars that the first scheduled course correction has been postponed. Engineers tentatively plan to execute a maneuver in late December or early January to begin the process of steering the spacecraft toward Mars. A burn in early June will start zeroing in on the precise landing site.
- The European Space Agency announced Friday it was ending efforts to establish communications with Russia’s Phobos-Grunt spacecraft after failing to restore control of the Mars probe. An ESA antenna in Australia had received signals from the spacecraft on November 22, but subsequent efforts from ESA facilities to establish two-way communications with and control of the spacecraft had failed.
- In a potential marriage of the Space Launch System (SLS) with a central exploration plan, a Boeing-authored presentation has proposed an Exploration Gateway Platform architecture that not only returns man to the lunar surface – via the use of only one SLS launch to a reusable Lunar Lander – but provides a baseline for pathfinders towards an eventual crewed mission to Mars.
- A Long March rocket launched the latest in a series of navigation satellites on Friday, in the process breaking a record for launch activity. The Long March 3A rocket lifted off from the Xichang Satellite Launch Center at 4:07 pm EST Thursday (2107 GMT Thursday, 5:07 am Beijing time Friday), carrying a Beidou-2 inclined geosynchronous orbit (IGSO) satellite.
- New images from Mars Express show the Phlegra Montes mountain range, in a region where radar probing indicates large volumes of water ice are hiding below. This could be a source of water for future astronauts.
- Burdened by the cut from $850 Million to $406 Million for Commercial Crew Development (CCDev), NASA is weighing whether to reduce funding to all four participants (SpaceX, Boeing, Sierra Nevada Corp. and Blue Origin. ), or cease funding one or more.
- In a bid to save the next Mars rover from budgetary oblivion, representatives from NASA, Europe and Russia will meet in Paris next week to hash out what each space agency can contribute to a pair of life-hunting Mars missions due to begin launching in four years.

- The website NASASpaceflight, has the details on the cracks found in the external tank of the Space Shuttle Discovery.
- Aerojet successfully test fired its AJ26 rocket engine at NASA’s Stennis Space Center in Mississippi. The AJ26 engine is an oxidizer-rich, staged-combustion LO2/Kerosene engine with a pintel injector. It achieves very high performance in a lightweight compact package. Based on the NK-33 engine originally designed and produced in Russia for the Russian N1 lunar launch vehicle, the liquid-fuel AJ26 will provide boost for the first stage of the Taurus II launch vehicle. The engine tested today is the first of four engines to be tested at Stennis throughout the next several months. This testing is being conducted to support the Taurus II Initial Launch Capability (ILC) in the third quarter of 2011.
- Beset by management problems, the James Webb Space Telescope (JWST) is like to cost 1.5 Billion more than budgeted, and slip from a launch in 2014 to late 2015.
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.

- 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.
- NASA and JPL have released more information on comet Hartley 2.
- The Spaceship Company (TSC), which plans to be the first to carry paying passengers into space, will break ground on its Final Assembly, Integration and Test Hangar (FAITH) production hangar at the Mojave Air and Space Port on Tuesday, 9 November 2010. The company is owned by Scaled Composites and Virgin Galactic and will produce the White Knight Two and Space Ship Two vehicles.
- Space Exploration Technologies (SpaceX) is awaiting U.S. regulatory approval to launch its Falcon 9 rocket and Dragon cargo vessel as soon as 20 November after more than a year spent tying up loose ends associated with the recoverable space capsule’s re-entry license application.

- The Mission Management Team (MMT) evaluations into the anomalies on the redundant Main Engine Controller (MEC) on SSME-3 have concluded with the approval for the required flight rationale, clearing Discovery to press ahead with Thursday’s launch attempt. Discovery’s next challenge is out of her control, with an 80 percent chance of unacceptable weather at T-0.
2 November 2010
- Discovery has been given another hurdle to negotiate ahead of her opening launch attempt, after an electrical issue was noted on the redundant Main Engine Controller (MEC) on SSME-3. The original problem had been classed as cleared, following cycling and troubleshooting. However, a Mission Management Team (MMT) meeting later on Tuesday decided to scrub for at least 24 hours to work towards flight rationale.
