- 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.

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.

- 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.
