7 February

  • Plans for the US and Europe to jointly carry out Mars missions is in danger of collapse because of a lack of NASA funding, the BBC reported Monday. The ExoMars program was to feature joint missions performed by NASA and ESA, including a US-launched European orbiter in 2016 and a joint NASA-ESA lander/rover mission in 2018. The BBC reported that NASA officials have alerted their European colleagues that NASA will likely withdraw from the program, most likely when the agency’s 2013 budget proposal is released next week, because of a lack of funding. NASA had already indicated to ESA it would not be able to launch the 2016 orbiter, forcing ESA to contact the Russian space agency Roscosmos about a potential Proton launch of the spacecraft.
  • The Russian report on the failure of the Fobos-Grunt spacecraft has been released, and it appears that Fobos-Grunt was doomed before it launched on November 9, 2011. Cheap parts, design shortcomings, and lack of pre-flight testing ensured that the spacecraft would never fulfill its goals. Its troubles became apparent a few hours after its launch, when it failed to fire thrusters to take it out of Earth orbit and on its way to Mars and its moon Phobos. It fell back to Earth on January 15.

6 February

  • China’s new generations of the Long March rockets, Long March-5, -6 and -7, are expected to make their maiden flights in the next five years. China is seeking to develop non-toxic, low-cost, highly reliable, adaptable and safe carrier rockets. The Long March-5 rocket will be using non-toxic and pollution-free propellant. It has a maximum low Earth-orbit payload capacity of 25 tonnes and geosynchronous orbit payload capacity of 14 tonnes. The Long March-6 is designed to be a high-speed response launch vehicle and has a minimum of 1 tonne of sun-synchronous orbit payload. The Long March-7 has a maximum low Earth-orbit payload capacity of 13.5 tonnes and 5.5 tonnes of sun-synchronous orbit payload.

5 February

  • NASASpaceFlight discusses the Space Launch System (SLS – Senate Launch System) and the efforts to seek DoD and other payloads in addition to the stated goals that would yield “…a flight rate of just one mission per year in the 2020s – an unacceptably low flight rate in most people’s eyes.”

4 February

  • Iran launched a small imaging satellite, the third satellite launched by the nation. A Safir-1 rocket lifted off from an Iranian base near Semnan, Iran, at shortly after 7 pm EST Thursday (0000 GMT Friday) and placed the Navid-e Elm-o Sanat satellite into low Earth orbit.

December 2011

Posted by drdave on December 1, 2011

31 December

  • 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.”

30 December

  • 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.

29 December

  • 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.

28 December

  • 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.

27 December

  • 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

26 December

  • 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.

25 December

24 December

  • NASASPaceFlight discusses the Soyuz failure with Meridian, and the redressing Russia’s internal woes.

23 December

  • 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

22 December

  • 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.

21 December

  • 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.

20 December

  • Russian Soyuz TMA-03M spacecraft set for launch to International Space Station

19 December

  • 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

18 December

  • 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.

17 December

  • 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.

16 December

  • 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.

15 December

  • 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.

14 December

  • 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.

13 December

  • 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.

12 December

  • 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.

11 December

  • 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.

10 December

  • 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.

9 December

  • 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.

8 December

  • 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.”

7 December

  • 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.

6 December

  • 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

5 December

  • 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.

4 December

  • 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.

3 December

  • 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.

2 December

  • 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.

1 December

  • 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.

Posted by drdave on April 1, 2011

30 April

  • NASA continues to work on the Space Shuttle Endeavour. Engineers expect to open the aft bay of the shuttle and begin testing of the heaters, Load Control Assembly and electrical cables by this evening. It is not certain that Endeavour will be ready for launch by the time its window opens on Monday, 2 May, at 11:33 AM Phoenix time (1833 UTC)

29 April

  • The Russian Progress M-10M resupply spacecraft has completed its docking with the International Space Station.
  • Next up, launch of the Endeavour STS-134 mission at 12:47 PM Phoenix time today. Scrubbed due to heater failures on the APU1 unit.

28 April

  • A Soyuz rocket lifted off from the Baikonur Cosmodrome in Kazakhstan at 6:05 AM Phoenix time (1305 GMT) and placed the Progress M-10M spacecraft into orbit. The spacecraft is carrying 2.6 tons of food, water, propellant, and other supplies for the International Space Station. Part of the spacecraft’s payload of experiments were considered time-sensitive enough by Russian officials that they declined to postpone the launch to avoid a scheduling conflict with the shuttle Endeavour, which was scheduled to launch on April 19. Instead, NASA had to delay Endeavour by ten days. The Progress is scheduled to dock with the Pirs module of the station at 10:29 am EDT (1429 GMT) Friday.
  • Get up in the wee hours of the morning May 6th and head out into the country, far from the city lights. You won’t be alone. The birds will be up and singing about the coming dawn, and, of course, about the eta Aquarid meteor shower. The eta Aquarids are best viewed from the southern hemisphere, but there’s something special about them no matter where you live: “Each eta Aquarid meteoroid is a piece of Halley’s Comet doing a kamikaze death dive into the atmosphere,” explains NASA astronomer Bill Cooke.

27 April

  • A team of Italian and US researchers have made lab equipment that recreates the jets that shoot out of stars and black holes. Astrophysical jets are narrow streams of charged particles spurting from the centre of young stars and supermassive black holes. They hurtle in opposite directions at near light speed.
  • SETI has placed the collection of 42 radio dishes in northern California called the Allen Telescope Array into “hibernation due to lack of funding.

26 April

  • Chinese authorities in charge of the manned space program unveiled plans on Monday to build a 60-ton space station, made up of three capsules, and develop a cargo spaceship to transport supplies. The 18.1-meter-long core module, with a maximum diameter of 4.2 meters and a launch weight of 20 to 22 tons, will be launched first. The two experiment modules will then blast off to dock with the core module. Each laboratory module is 14.4 meters long, with the same maximum diameter and launch weight of the core module. The 60-ton space station is rather small compared to the International Space Station (419 tons), and Russia’s Mir Space Station (137 tons).

24 April

23 April

  • The multibillion-dollar U.S.-European Mars exploration program has suffered a serious — but not fatal — blow with NASA’s confirmation that it can no longer afford to launch its own rover alongside a European rover in 2018.
  • The suborbital Virgin Galactic spacecraft SpaceShipTwo has completed its fifth unpowered flight. The glide test from high altitude lasted 14 minutes and 31 seconds.

22 April

  • Arianespace successfully launched the Ariane 5 rocket carrying the Yahsat Y1A and Intelsat New Dawn at 2:37 PM Phoenix time (2137 UTC) on April 22, 2011.
  • NASA’s Dawn spacecraft could settle the matter of whether Vesta is an asteroid or a “minor planet”. Originally spotted 200 years ago, it is officially a “minor planet”. It seems large for an asteroid at 530 km in width.
  • Russia will not permit the first U.S. commercial spacecraft (SpaceX Dragon) to dock with the International Space Station (ISS) unless its safety is fully tested, a high-ranking official with Russia’s space agency Roscosmos said on Friday.

21 April

  • Atlantis is tasked with the final mission as part of the Space Shuttle Program (SSP), with a launch date of June 28 resulting in a vital logistics run to the International Space Station (ISS). The current plan is for Atlantis to then retire at the Kennedy Space Center (KSC), as she becomes the centerpiece of a new exhibition.

20 April

  • An Indian rocket launched a remote sensing satellite and two smaller spacecraft on Wednesday. The Polar Satellite Launch Vehicle (PSLV) lifted off from the Satish Dhawan Space Centre in Sriharikota, India, on schedule at 9:42 PM Phoenix time Tuesday (0442 UTC, 10:12 am local time Wednesday). The rocket’s primary payload was Resourcesat-2, a 1,206-kilogram remote sensing satellite.
  • Shuttle managers on Tuesday confirmed plans to launch the space shuttle Endeavour on its final mission a week from Friday. Endeavour is scheduled to launch on STS-134 at 12:47 PM Phoenix time (1947 UTC) on Friday, April 29

19 April

  • NASA has awarded Space Exploration Technologies (SpaceX) $75 million to develop a revolutionary launch escape system that will enable the company’s Dragon spacecraft to carry astronauts. The Congressionally mandated award is part of the agency’s Commercial Crew Development (CCDev) initiative that started in 2009 to help private companies mature concepts and technologies for human spaceflight.
  • NASA has awarded seed money to four companies for work on commercial crew vehicles in the second round of its Commercial Crew Development (CCDev-2). A total of $269.3 million to help mature concepts for private spacecraft to carry astronauts to the International Space Station and other low-Earth-orbit destinations. Boeing received $92.3 million on top of the $18 million it won last year. Sierra Nevada Corp., last year’s top winner, will get $80 million to go with the $20 million it received in 2010. Space Exploration Technologies Inc. (SpaceX), which already has flown its Dragon cargo capsule to orbit and back, has been granted $75 million to develop a launch abort system and other hardware so the Dragon can carry crew. Blue Origin, the secretive startup organized by Amazon.com founder Jeff Bezos, was allotted $22 million to continue work on its vertical takeoff and landing craft.

18 April

  • Launcher and pad preparations to boost the Ukraine-built Cyclone-4 from Brazil’s Alcantara launch center are entering their final phase, with the goal of completing the qualification liftoff next year.

17 April

16 April

  • Space.com discusses the new NASA budget. The new budget at least frees NASA from a stifling provision under its 2010 budget that prevented it from cutting funding to the moon-bound Constellation program. Yet that program was canceled by President Barack Obama in early 2010, and NASA has been targeting new goals ever since.

15 April

  • The March 30 launch abort of Europe’s Ariane 5 rocket after the main engine had been ignited was caused by one or more components attached to the engine nozzle that prevented the nozzle from moving freely during ignition, the head of the Arianespace launch consortium said April 15.
  • In Texas, County Commissioner Calls for a Congressional Investigation why no Space Shuttle is coming to Houston.
  • Two small U.S. military satellites are queued up and waiting to ride into space on Minotaur rockets in May, but managers want to make sure the boosters are immune from the glitch that doomed the launch of a NASA science mission in March.
  • How many flights will the US Air Force X-37B make? Perhaps as few as two, perhaps three.

14 April

  • Wayne Hale, former NASA Space Shuttle Program Manager, explains why Houston did not get a Space Shuttle: “Because we just don’t care enough to do anything about it.”
  • The United Launch Alliance’s Atlas V rocket has performed its twenty-fifth launch, delivering into orbit the classified NROL-34 payload for the US National Reconnaissance Office. The launch took place from Vandenberg Air Force Base in California at 04:24 UTC Friday (9:24 PM Phoenix time Thursday).
  • Spending bill will put an end to the Constellation program

13 April

  • Boeing expects to select a single vehicle next month from an unspecified number of rockets in the running to launch unmanned flight tests and early crewed missions of the seven-person CST-100 space taxi it is developing with financial backing from NASA. The four real candidates are: United Launch Alliance’s Delta 4 and Atlas 5, Space Exploration Technologies’ Falcon 9, the European Ariane 5.
  • The Vostok 3KA-2 space capsule was sold for nearly $2.9 million in a Sotheby’s auction to Russian businessman Evgeny Yurchenko. The spacecraft flew in space in March 1961, 20 days before the historic April 12, 1961 launch of cosmonaut Yuri Gagarin on the first human spaceflight.
  • Celestial Fireworks from Dying Stars.

12 April

  • NASA’s space shuttles, which have been carrying astronauts aloft for 30 years, were assigned to their final destinations on Tuesday: one will head to the nation’s capital, another to Los Angeles, and the third from its current home at the Kennedy Space Center in Florida to the center’s visitor complex next door.
  • Yuri’s Night celebration in Moscow.
  • The Adler Planetarium will soon be home to a space flight simulator used to train every shuttle astronaut who has traveled to space.

11 April

  • Arianespace announced that “With the additional checkout and verification now in progress on the Ariane 5 ECA launcher, Arianespace has decided to resume the operations for Ariane Flight VA201 with the Yahsat Y1A and Intelsat New Dawn satellite payloads.”
  • Engineers and scientists eagerly unpacked the Juno spacecraft from its shipping crate Saturday, kicking off nearly four months of launch preparations before the $1 billion mission is shot toward Jupiter this summer.

10 April

  • Following a meeting between NASA and Russian Space Agency (Roscosmos) managers on Friday, a decision was made to call off the planned Soyuz documentary flyabout of the International Space Station (ISS) and Endeavour during the STS-134/ULF-6 mission, due to concerns with crew impacts in the event that the Soyuz should fail to re-dock with the ISS. Flyabout planning efforts are now shifting to the STS-135/ULF-7 mission.

9 April

  • Plans to launch an Atlas 5 rocket from Vandenberg Air Force Base next week have been delayed two days by a need to replace a questionable part on the space booster. The team now is shooting for a blastoff from Space Launch Complex-3 East on South Base at 9:24 PM Thursday, 14 April, carrying a National Reconnaissance Office spacecraft to orbit for a clandestine mission.
  • NASA’s Juno spacecraft has arrived in Florida to begin final preparations for a launch this summer. The spacecraft was shipped from Lockheed Martin Space Systems, Denver, to the Astrotech payload processing facility in Titusville, Florida. The solar-powered Juno spacecraft will orbit Jupiter’s poles 33 times to find out more about the gas giant’s origins, structure, atmosphere and magnetosphere.

8 April

  • NASA’s Swift satellite, Hubble Space Telescope and Chandra X-ray Observatory have teamed up to study one of the most puzzling cosmic blasts ever observed. More than a week later, high-energy radiation continues to brighten and fade from the gamma-ray burst.
  • Space.com presents a compilation of “Firsts” in the Space Age on the eve of the 50th anniversary of Yuri Gagarin’s manned spaceflight.
  • April is proving to be the cruelest month for the Laser Interferometer Space Antenna (LISA), a major space mission to look for gravitational waves that was slated for launch around 2015. But news broke this week that NASA is abandoning funding for the project, which means the U.S. will cede its role in developing this critical instrument in order to redirect funds to the James Webb Space Telescope (JWST).

7 April

  • The Russian Soyuz TMA-21 piloted spacecraft docked with the International Space Station (ISS). The new ISS crew consists of Russians Alexander Samokutyayev and Andrei Borisenko, and U.S. astronaut Ronald Garan.
  • NATURE reports that NASA is disbanding two major US science teams following a bilateral meeting with the European Space Agency, Nature has learned. In a public presentation April 4, Jon Morse of NASA Astrophysics Division said that the International X-ray Observatory Science team and the Laser Interferometer Space Antenna (LISA)’s International Science Team will formally no longer exist and the project offices are closing.
  • Virgin Galactic dropped the White Knight Two and Space Ship Two on the San Francisco Airport Thursday. Watch the video from Wired.

6 April

  • Space Exploration Technologies (SpaceX) head Elon Musk revealed their latest launch vehicle on Tuesday, the Falcon Heavy. Effectively three Falcon 9 core stages strapped together, the new vehicle – set to debut as soon as 2013 – will be the most powerful US rocket to have launched since the Saturn V was built for the Apollo Program, eventually sharing a 20 missions per year manifest with the Falcon 9.

5 April

  • Chinese Space Junk Won’t Hit Space Station
  • Russia’s Soyuz TMA-21 spacecraft, which also goes by its American designation of 26S, has blasted off from the Baikonur Cosmodrome in Kazakhstan on Monday (4th April) at 10:18:20 PM GMT, carrying three crew-members for the International Space Station’s (ISS’) Expedition 27 and Expedition 28 crews.

4 April

  • The scheduled April 19 launch of the space shuttle Endeavour is expected to be postponed for at least 10 days, sources close to the project said Sunday. The glitch evidently has to do with a scheduling conflict involving a Russian resupply craft, the Progress, which was to launch a few days after the Endeavour. That craft cannot dock with the International Space Station while the shuttle is there, and NASA had hoped to persuade the Russians to agree to put the Progress into a “parking” orbit until the Endeavour had completed its mission.

3 April

  • NASA has announced the winners of the 18th annual NASA Great Moonbuggy Race — and it’s Puerto Rico’s year. Teams representing Teodoro Aguilar Mora Vocational High School of Yabucoa, Puerto Rico, snared the top two berths in the high school division; and, for the second straight year, the University of Puerto Rico in Humacao held off all comers to win the college division.
  • The New Scientist discusses stars that orbit the wrong way in their galaxy’s heart are probably the remnants of another galaxy that was eaten. Astronomers have noted for years that the stars at the heart of some galaxies orbit in the opposite direction to that of their neighbours further out.
  • NASA managers have been presented with a working plan and completed assessments on the potential for a Soyuz fly-around of the Shuttle/Station stack during Endeavour’s docked mission. With many of the hurdles from the canceled STS-133 fly-about plan removed, the unique event has a high potential of being approved by the International Space Station (ISS) partners.

2 April

  • Russia’s soyuz TMA-21 rocket has been moved into position at the Baikonur launch pad in Kazakhstan before the scheduled blast off date on Tuesday. The craft will have an international crew of US astronaut Ron Garan, and Russian cosmonauts Aleksander Samokutyaev and Andrei Borisenko.
  • The Endeavour astronauts followed a realistic countdown sequence Friday, getting suited up and strapping inside the space shuttle for a thorough dress rehearsal that culminated with a pretend ignition and shutdown of the three main engines at T-minus 4 seconds.

1 April

  • More than 70 million observations during the past two 2 years in orbit from ESA’s GOCE satellite has given scientists their most detailed map yet of Earth’s gravitational field. The lumpiness of that geoid—the theoretical surface that a planet-wide ocean would take if there were no tides or currents—betrays the irregularity of the planet’s mass distribution, including concentrations of mass such as mountain ranges and ice sheets.
  • The Soyuz site at Europe’s Spaceport in French Guiana is now ready for its first launch. ESA yesterday handed over the complex to Arianespace, marking a major step towards this year’s inaugural flight.
