The launch of space shuttle Endeavour was scrubbed about 9 minutes before the scheduled 4:39 am EST (9:49 GMT) liftoff due to low clouds that moved into the area. Mission managers have scheduled space shuttle Endeavour's next launch attempt for Monday, Feb. 8 at 4:14 a.m. EST (9:14 GMT)

The Mission Management Team will meet at 6:15 p.m. Sunday to give the "go" to fill Endeavour's external fuel tank with propellants. Tank loading will begin at 6:45 p.m.

The launch of the Solar Dynamic Observatory has subsequently been moved one day forward, and is now scheduled for Feb. 10 at 10:26 am EST.

Note: Nancy Atkinson is at Kennedy Space Center covering the launch of STS-130

The official countdown clock is ticking for the STS-130 mission of space shuttle Endeavour to the International Space Station. This is the last planned night launch for the shuttle program, with a scheduled liftoff time of 9:39:47 GMT (4:39:47 a.m. EST) on Sunday, February 7. "Everything thus far is going exceeding well… we're right on schedule where we're supposed to be and we'll continue to work through the day on our preparations," said NASA Test Director Jeff Spaulding during this morning's L-3 Countdown Status Briefing at KSC. The weather forecast might be the only issue, as forecasters are predicting a 70% chance of favorable weather, with high winds being the only concern for Sunday morning.

Mission Control: "Challenger, go at throttle up"

Commander Dick Scobee: "Roger go at throttle up"

Those were the last words heard from the Challenger crew on January 28, 1986. Then came an explosion, and the famous "Y" plume of smoke from the solid rocket boosters flying away aimlessly to nowhere.

Mission Control: "Flight Controllers looking carefully at the situation. Obviously a major malfunction."

Today we remember the Challenger crew, pictured above: (front row) Michael J. Smith, Dick Scobee, Ronald McNair; (back row) Ellison Onizuka, Christa McAuliffe, Gregory Jarvis, Judith Resnik.

Looking for a way to remember the crew, or want more insight on the mission or accident? Read a UT article from Sept. 2008 of how Christa McAuliffe's lost lesson plans have been given new life by a caring NASA engineer. Read a poem written by Stuart Atkinson about the Challenger accident. On Twitter, people are writing short remembrances of where they were when they heard the news. Below are more ways to remember the crew, and if you'd like, add a comment on your thoughts about the accident/or your recollections from that day.

Liftoff of space shuttle Endeavour for the STS-130 mission to the International Space Station has been been given the go-ahead, and launch is scheduled for Feb. 7 at 4:39 a.m. EST. Universe Today will be at the launch to provide on-site coverage of all the pre- and post-launch events, and we look forward to sharing the experience with you. This is likely the last night launch of the space shuttle, and it should be a beautiful sight.

STS-130 will bring the Tranquility node and a cupola, a 7-window observation portal for the ISS. Mission managers said at a press briefing today that the issue with problematic ammonia coolant hoses on the module has been resolved. The 7-member crew will carry out three spacewalks to install and outfit the Tranquility node.

Astronauts say it is the most-asked question they get from people. There have been books written about it. Maybe because we all have to do it, everyone wants to know how it works in zero-gravity. This past weekend I gave a presentation to about 60 Girl Scouts about living and working in space, and I knew this question was going to come up. It did, and with this video, I was prepared. Here, Canadian astronaut Chris Hadfield gives the best description ever of how it works to go to the bathroom in space. And he tells all in less than two minutes, too.

To get something into space right now, you need a rocket. You also need a lot of money, as the current going rate for getting something into orbit is about $5,000 a pound ($11,000 per kg). But what if you could, instead, do away with the rocket and still get your payload to space, for under $1,000 a pound? Sounds like a deal, right.

According to Dr. John Hunter, a physicist at Lawrence Livermore National Laboratory and president of the company Quicklaunch, Inc., using a hydrogen-powered cannon may be the ticket for cheap access to space. That's right, a "space gun" platform for inserting satellites, fuel, and other supplies into space genuinely could be the next big thing in space technology. Read more…

China is planning to launch their own space station, named Tiangong, by the end of 2010 or beginning of 2011. There have been a few instances where information about the station surfaces briefly over the past few years about the development of the space station. Specific details on the program are not being release in large doses by the Chinese National Space Administration (CNSA), so the development of the station is somewhat shrouded in mystery.

Qi Faren, one of the designers of the Shenzhou-5 spacecraft, said in an interview on CCTV last month of the upcoming launch, "Quality is the key to technology. We must guarantee a successful launch. We will launch it whenever we are ready. It will be the end of 2010, or the beginning of 2011." Read more…

Researchers hoping to conduct scientific experiments on commercial suborbital spacecraft completed the first-ever round of training last week at the National Aerospace Training and Research (NASTAR) Center in Pennsylvania. The researchers hope to take advantage of the prospect of quick, low-cost and frequent access to the microgravity environment of suborbital space. They successfully went through full-flight simulation spins in a centrifuge and altitude chamber to simulate the physiological conditions that scientist-astronauts will experience during future missions to 100 km or more altitude. Additionally, they received training on how to best accomplish their science goals in the short 4-6 minute window of zero-g in an actual suborbital flight.

NASA managers decided on Tuesday (Jan. 12) to press forward towards an on time liftoff target date of Feb 7 for Space Shuttle Endeavour as engineers developed a workaround solution to the ammonia coolant hose leak issue which has threatened to delay the launch or seriously alter the mission goals (read my earlier post). The ammonia jumper hoses are critical to the success of the STS 130 mission because they will supply cooling capacity to the new Tranquility module by circulating ammonia and transport the heat generated by the on board systems. Space walking astronauts must connect the hoses from Tranquility to the space station’s cooling system during the STS 130 flight in order to fully activate Tranquility for use by the orbiting outposts crew.

(Editor's Note: Ken Kremer is in Florida for Universe Today covering the pre-launch activities of Endeavour.)

The launch of Shuttle Endeavour on the STS 130 flight now faces a potential delay due to technical problems with the external ammonia connecting lines which are designed to provide critical cooling capability to the new Tranquility module. Tranquility is a pressurized module being brought aloft as payload in the cargo bay of Endeavour on the STS 130 mission. Launch of Endeavour is currently set for 4:39 AM on Feb. 7.

The new joint Mars exploration program of NASA and ESA is quickly pushing forward to implement an agreed upon framework to construct an ambitious new generation of red planet orbiters and landers starting with the 2016 and 2018 launch windows.

The European-led ExoMars Trace Gas Mission Orbiter (TGM) has been selected as the first spacecraft of the joint initiative and is set to launch in January 2016 aboard a NASA supplied Atlas 5 rocket for a 9 month cruise to Mars. The purpose is to study trace gases in the martian atmosphere, in particular the sources and concentration of methane which has significant biological implications. Variable amounts of methane have been detected by a martian orbiter and ground based telescopes on earth. The orbiter will likely be accompanied by a small static lander provided by ESA and dubbed the Entry, Descent and Landing Demonstrator Module (EDM). Read more…

Heat shields are an important part of any space vehicle that re-enters the Earth's atmosphere. The next generation of heat shields to protect astronauts and payloads on their re-entry into the Earth's atmosphere may use superconducting magnets to deflect the plasma that forms in front of spacecraft as they travel at high speeds in the air. The first test of such a heat shield could happen as early as ten years from now, and the basic technology is already in development. Read more…
