- A Russian Soyuz rocket is set for liftoff at 0202:50 UTC Saturday (7:02:50 PM Phoenix time Friday) from the Guiana Space Center with the sharp-eyed Pleiades 1B Earth observation satellite to collect high-resolution imagery for French and European security services. It will join the Pleiades 1A satellite launched in December 2011, forming a two-spacecraft constellation placing every part of Earth in range of their cameras each day.
- Stratolaunch Systems has turned to Orbital Sciences Corp. of Dulles, Va., to keep the world’s largest air-launch-to-orbit system on track for a 2017 test flight. Stratolaunch and SpaceX parted ways was because SpaceX, decided it did not want to disrupt its Hawthorne, Calif., assembly line to accommodate the design changes required to turn its nine-engine, liquid-fueled Falcon 9 into a four- or five-engine air-launched booster.
- Curiosity on Mars: Rumors and speculation that there are major new findings from the mission at this early stage are incorrect. The news conference will be an update about first use of the rover’s full array of analytical instruments to investigate a drift of sandy soil. One class of substances Curiosity is checking for is organic compounds — carbon-containing chemicals that can be ingredients for life. At this point in the mission, the instruments on the rover have not detected any definitive evidence of Martian organics.
- South Korean engineers scrubbed Thursday a second attempt to launch a rocket, citing technical problems with the rocket’s second stage. The Korea Space Launch Vehicle (KSLV)-1 rocket, also known as Naro-1, was to launch from South Korea’s launch site, the Naro Space Center, at 2 am EST (0700 GMT, 4 pm local time) Thursday, but the countdown was halted 17 minutes before the scheduled liftoff time.
- Scientists Thursday announced new evidence from the MESSENGER spacecraft that Mercury, the planet orbiting nearest the Sun, hosts massive caches of ice and revealed new information on how water reached our solar system’s inner planets.
- A Long March 3B rocket launched a Chinese communications satellite that will be used, in part, by a Sri Lankan company. The rocket lifted off from the Xichang Satellite Launch Center at 3:13 AM Phoenix time (1013 UTC) Tuesday and placed the Chinasat-12 satellite into geosynchronous transfer orbit. The satellite, a Spacebus 4000 model built by Thales Alenia Space, weighed approximately 5,000 kilograms at launch and carries a payload of C- and Ku-band transponders.
- Capt. Scott Kelly, a veteran astronaut, will set the record for the longest single space mission for an American, NASA announced Monday. Kelly and Roscosmos cosmonaut Mikhail Kornienko will embark on a one-year mission to the International Space Station in 2015. The duo will help scientists explore the effects of living in space on the human body, NASA said. They will provide information regarding health and crew performance and help with determining and validating risk-reduction measures. All of this can help contribute to planning for missions to other celestial worlds, such as an asteroid or Mars.
- It is not every day that astronauts can claim to return to Earth with a new species of life. But when the astronauts on ESA’s CAVES underground training course returned to the surface they were carrying a special type of woodlouse.
- A Long March 4C rocket lifted off from the Jiuquan Satellite Launch Center at 11:06 pm EST Saturday (0406 GMT, 12:06 pm Sunday Beijing time) and placed the Yaogan 16 satellite into orbit. The satellite will be used for a variety of earth sciences and disaster management applications.
- Whatever Curiosity has found in the way of organic molecules on Mars, Stuart Clark at the Guardian observes that “… it is not evidence for life on Mars. It can’t be. Curiosity is not designed to look for life. Grotzinger has stated this himself.”
- Space fans anticipate news of organic molecules from the Mars Curiosity rover, which were cryptically teased by the mission’s chief scientist, John Grotzinger. Grotzinger has refused to elaborate, pointing New Scientist, and other journalists, to a presentation scheduled for the American Geophysical Union annual meeting in San Francisco, which begins on 3 December.
- Member states of the European Space Agency (ESA) and Canada met in Naples, Italy, to determine the space agenda and the budget for the next five years.

- Astronomers observing a stellar occultation by the dwarf planet Makemake found no evidence of an atmosphere around the distant, icy world. Astronomers observed the occultation using three telescopes at the European Southern Observatory (ESO) in Chile in April 2011 as the dwarf planet, about two-thirds the size of Pluto, passed in front of a distant star. The star abruptly disappeared and then reappeared, a telltale sign that there is no atmosphere around the dwarf planet.
- The European Space Agency got the green light on 21 November to push ahead with a new generation of launchers and take its first foray into manned spacecraft, with a €10 billion ($12.9 billion) budget agreement for the next five years. Meeting in Naples, ministers in charge of space and science from the governments of the space agency’s 20 member states broadly signed up to ESA proposals to improve its Ariane 5 heavy launcher, begin design of a successor – Ariane 6 – and design and build a service module for NASA’s multi-purpose crew vehicle (MPCV) as part of ESA’s “barter arrangement” to the running costs of the International Space Station.
- SpaceX intends to build a methane/liquid oxygen (Lox) engine, said founder Elon Musk, in a shift away from the highly refined kerosene rocket propellant (RP-1) that has powered the company’s previous engines. Speaking at the Royal Aeronautical Society in London, SpaceX chief executive and lead rocket engineer Musk said Lox and methane would be SpaceX’s propellants of choice on a mission to Mars, which has long been his stated goal.
- The European Space Agency (ESA) have announced they will inform NASA they are ready to build an ATV derived Service Module for Orion, to be ready for the first launch of the Space Launch System (SLS) in 2017. The announcement came after the UK stepped up with additional funding, marking the country’s first real human BEO commitment.
- A Proton rocket successfully launched an American communications satellite on the same day that the company that markets the Proton commercially replaced its president. The Proton M rocket lifted off from the Baikonur Cosmodrome in Kazakhstan at 1:31 pm EST Tuesday (1831 GMT Tuesday, 12:31 am local time Wednesday). Its Breeze M upper stage released the EchoStar 16 satellite into a geosynchronous transfer orbit 9 hours and 12 minutes after liftoff. The satellite, a Space Systems/Loral 1300-series satellite, weighed 6,683 kilograms at launch and carries 36 Ku-band transponders.

- Dragon splashed down at 1542 UTC. Recovery is in process at 1610 UTC.
- Dragon has demated from the ISS and is scheduled to make its deorbit burn at 7:51 Phoenix time (1451 UTC).
- Astronomer Jason Kalirai of the Space Telescope Science Institute in Baltimore, Maryland, has created a new method to measure the ages of individual halo stars. His technique exploits a basic concept of stellar evolution: The heavier a star is, the faster it dies. Halo stars die by becoming red giants and then white dwarfs—dense stars little larger than Earth. White dwarfs have no nuclear activity, so as they age, they cool and fade. Thus, the hottest and brightest of these burnt-out stars entered the white-dwarf stage most recently.
- Preparations for the second landing of the X-37B, the Air Force’s unmanned, reusable space plane, are underway at Vandenberg Air Force Base. While the exact landing date and time will depend on technical and weather considerations, it is expected to occur during the early- to mid-June timeframe. Space professionals from the 30th Space Wing will monitor the de-orbit and landing of the Air Force’s X-37B Orbital Test Vehicle mission, called OTV-2.
- Excalibur Almaz has detailed its plans to launch spacecraft to space stations in orbit around the moon, the first time the secretive company has done so publically. The British company will use legacy Russian hardware, capsules from the Soviet Soyuz space programme and space stations from Salyut, to launch people into orbit around the moon. Both capsules and stations will undergo upgrades, but the basic hardware has flown in space up to nine times, and is described by Excalibur CEO Art Dula as have a technical readiness level of nine, the highest possible.
- Intelsat, the world’s leading provider of satellite services, and Space Exploration Technologies (SpaceX), the world’s fastest growing space launch company, announced the first commercial contract for the Falcon Heavy rocket.
- A Chinese Long March 4C has launched with a military payload, understood to be the Yaogan 15 military satellite, from the Taiyuan Satellite Launch Center. Launch was recorded at 0731 UTC, catching out most observers, with the only news of the launch on Tuesday leaking out on the internet, prior to official media reports of a successful ride to orbit.
- With Dragon now installed and ingressed on the International Space Station (ISS), Canada’s Dextre robot took an opportunity to greet the new spacecraft on Sunday. The SPDM (Special Purpose Dexterous Manipulator) was translated to the SpaceX vehicle to practice the removal of cargo from the trunk, a key element of future Commercial Resupply Services (CRS) missions.
- China launched a satellite late Saturday for civil and possibly military communications. The Long March 3B rocket lifted off from the Xichang Satellite Launch Center at 8:56 AM Phoenix time (1556 UTC) Saturday and placed the 5,200-kilogram Chinasat 2A satellite into a geosynchronous transfer orbit.
- The hatch on the Dragon spacecraft has been successfully opened, and the ISS crew is beginning to unload the 1014 lbs of cargo brought up on the spacecraft. 1367 lbs of cargo is scheduled to return on Dragon on 31 May.
- A giant distributed radio telescope will be split over sites in South Africa and Australia, astronomers announced Friday. The Square Kilometer Array (SKA) Organization said Friday that dishes for the radio telescope will be built on sites in South Africa and Australia, with the majority of the telescopes being placed in South Africa.
- Dragon is berthed to the International Space Station.
- The Dragon spacecraft has passed all of the Approach tests and is proceeding toward Capture.
- Boeing successfully completed the software Preliminary Design Review (PDR) for its Commercial Crew Development (CCDev-2) initiative on May 18. CCDev-2 is part of NASA’s Space Act Agreement. Software competency is essential to all operational aspects of Boeing’s Crew Space Transportation (CST)-100 spacecraft, including launch, orbital maneuvering, docking with and separating from the International Space Station, re-entry and landing. The PDR team analyzed the system’s flight software, including details regarding safety, testing, overall redundancy management, avionics hardware and ground systems.
- XCOR announced today that it has achieved a key technical milestone with its flight weight rocket piston pump hardware. XCOR engineers have successfully and repeatedly pumped liquid oxygen (LOX) at flow rates required to supply the Lynx suborbital vehicle main engines.
- SpaceX and Dragon completed today’s fly-under successfully.
- The Union of Concerned Scientists (UCS) announced Monday that Iran is set to launch a satellite called Fajr (or “Dawn”) atop a Safir 1B rocket on a mission to demonstrate the country’s first use of a maneuverable spacecraft in orbit.
- The SpaceX Dragon capsule has completed Flight Day 1 objectives (under final review by NASA and SpaceX), and will spend Flight Day 2 raising its orbit as it approaches the International Space Station. If all objectives are met, grappling is set for 1206 UTC Friday.
- SpaceX successfully launched their Falcon 9 rocket and placed the Dragon capsule on a rendezvous path to the International Space Station (ISS). If all tests are successful, grappling and connecting to the ISS will occur on Friday morning.
- When SpaceX’s Dragon capsule launches in spring 2012, a very special payload will be on board: 15 student experiments from the Student Spaceflight Experiments Program. The big deal is that those experiments from “SSEP Mission 1 to ISS” will be part of space history. Dragon will become the first commercial vehicle to dock to the International Space Station, and these student experiments have the distinction of being the only payload on board.
- The SpaceX Falcon 9 launch vehicle aborted following engine start. Engine 5 recorded high pressure. The launch will be rescheduled for 22 May (NET).
- From SpaceX on Facebook: “Engineers replacing failed valve on engine #5 following today’s abort. Data review Sunday, if all looks good next attempt is Tues. May 22 at 3:44 AM ET”.
- NASA and SpaceX held a pre-launch briefing this afternoon at Kennedy Space Center. View the briefing here.

- Scientists analyzing data from NASA’s Dawn spacecraft orbiting the large asteroid Vesta have concluded that the body has some of the key characteristics of a planet, suggesting it is a protoplanet left over from the solar system’s formation. Observations of the asteroid show that it is a differentiated body, featuring an iron core with a radius of 110 kilometers as well as a mantle and crust.
- The Indian Space Research Organization on Saturday successfully tested the indigenous cryogenic engine at the Liquid Propulsion Systems Centre (LPSC) at Mahendragiri for 200 seconds. The engine will undergo another two more tests, including endurance test of 1,000 seconds and vacuum ignition test. The engine is scheduled to propel GSLV D-5 in September or October.
- John Kelly heaps scorn on the Congressional move to force NASA to prematurely select a single manned spacecraft contractor, “History shows going with one contractor results in years of delays and billions of dollars in cost overruns. Every past space transportation system development effort has become a cost and schedule boondoggle, often made worse by cost-plus contracting.”
- One of the key pre-launch requirements for SpaceX’s upcoming Dragon mission to the ISS, the completion of software validation tasks for the spacecraft’s approach and berthing with the orbital outpost, has been passed, pending the expected completion of “action items”. The milestone means the latest launch date target of May 19 now holds a large amount of confidence.
- Scientists are on an epic treasure hunt for meteorite fragments from a spectacular fireball that lit up the daytime sky over California last month. The space rocks came from a minivan-size asteroid that plunged through Earth’s atmosphere and exploded into a dazzling daytime fireball over California and parts of Nevada on April 22. Meteorite fragments were scattered around Sutter’s Mill, an old sawmill in Coloma, California.
- The Sun moves much more slowly relative to nearby interstellar space than was previously thought, according to scientists working on NASA’s Interstellar Boundary Explorer (IBEX) mission. Their study casts doubt on the existence of an abrupt “bow shock” where the edge of the solar system meets the interstellar medium – instead suggesting that the boundary between the two regions is much gentler.
- Virgin Galactic expects to resume flight tests of its SpaceShipTwo suborbital vehicle as early as June from manufacturer Scaled Composites’ facility in Mojave, California. SpaceShipTwo has not flown since its 16th glide flight in September, 2011, when it entered a tail stall upon release from its WhiteKnightTwo carrier aircraft.
- Envisat, an enormous Earth-observing satellite that was officially declared dead in space Wednesday (May 9) may stay in orbit for the next 150 years, posing a threat to other spacecraft zipping around our planet.
- NASA’s Juno Spacecraft Images Big Dipper
- NASA’s Dawn spacecraft won’t end its 13-month-long visit to Vesta, the Solar System’s second biggest asteroid, until August, but researchers have now solidified the rock’s reputation as an archetype for understanding planetary evolution. In six reports in the 11 May edition of Science, Dawn mission scientists have confirmed several long-held assumptions about Vesta and detailed some puzzles about the roughly 520-kilometer-diameter body.
- Four days after the launch of Tianhui-1B mapping satellite, China has launched a new optical remote sensing satellite on May 10, 2012 from the Taiyuan Satellite Launch Center. Launch of Yaogan Weixing-14 (YG-14) satellite took place at 07:06UTC using a Long March 4B (Chang Zheng-4B) launch vehicle from the LC9 launch complex.
- OpenMarket.org has a screed about “Republican Space Socialism Update”, taking House Appropriations Chairman Frank Wolf (R-Virginia) to task for decrying the wastefulness of competition in the Commercial Crew Development program.
- Unionized workers at United Launch Alliance (ULA), the Boeing-Lockheed Martin joint venture that makes the Atlas and Delta launch vehicles, ratified a new contract by default on Sunday when a strike vote fell just short of passage. Members of the International Association of Machinists and Aerospace Workers (IAMAW) voted Sunday to reject a three-year contract offered by ULA, but a subsequent vote on whether to strike fell just short of the two-thirds majority needed to authorize a strike. Because the strike vote failed, the new contract went into force at midnight Monday.
- Commercial remote sensing company DigitalGlobe has rejected a offer by rival GeoEye to acquire the company, saying it will wait until the end of the federal budget cycle to make a decision on whether to make its own bid to acquire GeoEye. DigitalGlobe said in a statement Sunday that the $17-per-share offer by GeoEye “substantially undervalues” the company.
- Preparations for Orion’s first journey into space are accelerating, as flight controllers at the Johnson Space Center (JSC) fire up the former Shuttle Flight Control Room (FCR) for mission simulations, while Michoud Assembly Facility (MAF) engineers finalize the vehicle’s baseline construction, ahead of shipping Orion to the Kennedy Space Center (KSC) for outfitting.
- In a study published online today in the Proceedings of the National Academy of Sciences, astronomers analyzing 63 hot Jupiters (depicted above) detected by NASA’s Kepler spacecraft have found no planets comparable in size to Earth orbiting nearby. In contrast, many hot Neptunes—close-in giant worlds with roughly 5% of Jupiter’s mass—do have planetary neighbors. The findings may mean that hot Jupiters assume their peculiar orbits after far-off giant planets kick them close to their suns. As the hot Jupiter dashes inward, its gravity ejects any smaller planets near the star, both explaining the absence of close planetary neighbors and suggesting that solar systems with hot Jupiters are unlikely to host life-bearing worlds resembling Earth.
- China launched the second TH-1 Tianhui-1 satellite – Tianhui-1B – on Sunday, using a Long March 2D (Chang Zheng-2D) launch vehicle from the Jiuquan Satellite Launch Center. Launch took place at 07:10UTC from the 603 launch pad from the LC-43 launch complex. Tianhui-1B will conduct Earth-mapping using stereo-topographic techniques.
- Supermoon: “We will have moon closest to the Earth at the exact moment, or within a minute or two of when it becomes full,” says Andrew Fraknoi at Foothill College in Los Altos, Calif., and senior educator at the Astronomical Society of the Pacific. “And this has no cosmic danger or significance but it means the moon will be a little bit brighter and a little bit bigger in our sky.”
- NASA issued the following statement from William Gerstenmaier, associate administrator for Human Exploration and Operations at the agency’s Headquarters in Washington: “After additional reviews and discussions between the SpaceX and NASA teams, we are in a position to proceed toward this important launch. The teamwork provided by these teams is phenomenal. There are a few remaining open items but we are ready to support SpaceX for its new launch date of May 19.”
- SpaceX and NASA are nearing completion of the software assurance process, and SpaceX is submitting a request to the Cape Canaveral Air Force Station for a May 19th launch target with a backup on May 22nd.
- The European Space Agency (ESA) announced Wednesday that it has chosen a mission to several of Jupiter’s largest moons as its next large mission, confirming a choice made last month by an agency panel. The JUpiter ICy moon Explorer, or Juice, is planned for launch in 2022 and arrive at Jupiter in 2030. The spacecraft would fly by the Galilean moons of Callisto and Europa before entering orbit around Ganymede, the solar system’s largest moon.
- ULA: “The launch of an Atlas V carrying the United States Air Force’s Advanced Extremely High Frequency-2 (AEHF-2) payload was scrubbed today due to lack of helium flow from the ground support equipment to the Interstage Adapter compartment on the launch vehicle. The Atlas V vehicle and AEHF-2 are safe and secure at this time. The launch is rescheduled for Friday, May 4 from Space Launch Complex-41 at Cape Canaveral Air Force Station, Fla. The opening of the launch window is 2:42 p.m. EDT and extends until 4:42 p.m. The forecast for May 4 shows an 80 percent chance of favorable weather conditions for the launch tomorrow. “

- SpaceX said Wednesday it is “unlikely” that Monday’s scheduled launch of a Dragon spacecraft on a Falcon 9 rocket will proceed because of additional testing being done on the spacecraft. The company said in a brief statement Wednesday afternoon that the Monday morning launch was unlikely to take place as scheduled to allow the company more time to work on software assurance issues regarding the Dragon spacecraft with NASA. No official launch delay had yet been announced, although some NASA documents has already pushed the launch back to the backup date of May 10.
