The Space Shuttle Endeavour undocked from the International Space Station Friday night leaving it virtually complete after this mission's 2 successful spacewalks.

The Endeavour crew installed the Italian Tranquility Node and the Cupola observatory with will allow a nearly 360 degree view from the ISS.

Its 6 member crew is scheduled to land tonight however there are weather concerns at both Kennedy Space Center in Florida and Edwards Air Force base in California. Depending on conditions at those sites for each landing opportunity, the Endeavour could land at the White Sands facility in New Mexico.

NASA TV is now airing on Channel 12, so tune in for continuing coverage of STS-130, Endeavour's mission to the ISS and also tomorrow morning's launch of SDO! The Solar Dynamics Observatory's launch was postponed today due to high winds at KSC and has a launch window tomorrow morning from 10:23am - 11:23am with liftoff scheduled for 10:23am.

The Space Shuttle Endeavour and its six member crew are just a few minutes into their 13 day mission to the ISS!

The Endeavour rocketed into space in a brilliant early morning launch at KSC at 4:14:08 am punching through a thin layer of clouds on it's way to the ISS. Endeavour lifted off on time, after yesterday morning's scrub do to a low cloud ceiling. STS-130 is delivering the Tranquility Node 3 and the cupola that will allow virtually a 360 degree view of space from the ISS. The cupola will be used as a control room for robotics. The mission will feature three spacewalks.

This is the 24th flight of Endeavour.

NASA Television will broadcast a post-launch news conference from Kennedy Space Center in Florida at no earlier than 5:15 a.m. Click Here to watch.

4:47am 2/7/10

At 4:30am launch director Mike Leinbach made the call to scrub this morning's launch of Endeavour. Both SRO and Houston Flight were "No Go" for launch due to low cloud ceiling which violates launch criteria for not only ascent but RTLS (Return To Launch Site) abort procedures. A 24 hour launch scrub turn around is in place for a Feb. 8th launch attempt at 4:41am.

It had been a basically flawless countdown up to T minus 9 built in hold when the polls were taken. Assistant launch director Pete Nicholenko commented that computer models run and analyzed by NASA Weather Officer Kathy Winters couldn't and hadn't predicted cloud ceilings that were present at the launch site. Mike Leinbach while conducting his polls said in his many years he hadn't had experience with low cloud ceilings like this during a launch and was not comfortable giving a go.

Launch on Schedule, Tanking Complete
Sat, 06 Feb 2010 10:57:16 PM EST

Space shuttle Endeavour's external tank has been loaded with about 500,000 gallons of liquid hydrogen and liquid oxygen; the propellants that will power the shuttle's three main engines during launch.

Pumps at the launch pad will continue to trickle in a small amount of supercold chemicals to replace the amount that boils off during the countdown.

The Final Inspection Team and Closeout Crew will head out to the pad for their specialized tasks. The inspection team will look for signs of debris or ice buildup on the shuttle and external tank, while the Closeout Crew will prepare Endeavour for its crew of six.

Liftoff remains on schedule for 4:39 a.m. EST.

We are now less than 6 hours away from the launch of the Space Shuttle Endeavour!

Here's the latest from NASA.gov:

Fueling Continues Smoothly
Sat, 06 Feb 2010 07:58:30 PM EST

At NASA Kennedy Space Center's Launch Pad 39A, fueling of space shuttle Endeavour's external fuel tank with more than 500,000 gallons of liquid propellants began at 7:47 p.m. EST. The three-hour process will provide the fuel and oxidizer Endeavour's three main engines require for the 8 1/2 minute trip to orbit.

There is an 80 percent chance of favorable weather for launch.

NASA Television is providing live commentary of external tank loading and launch commentary and the NASA Launch Blog will begin at 11:30 p.m.

Due to declining weather conditions in the Kennedy Space Center area, Mission control has waved off both landing opportunities for today at KSC. Two landing opportunities at Edwards Air Force Base in the Mojave Desert in CA are possible later today.

The first landing opportunity at Edwards would be at 8:53 pm, ET, with deorbit burn at 7:47 pm ET on orbit 219 of the STS-128 mission. Poor weather conditions are expected at Kennedy and at Edward's tomorrow.

Friday Landing Opportunities in Florida and California

Mission Control has called off Thursday's final space shuttle landing opportunity at Kennedy Space Center due to unstable weather conditions.

Two more Discovery landing opportunities are available Friday at Kennedy Space Center. The first begins with a de-orbit burn at 4:41 p.m. EDT and ends with landing at 5:48 p.m. The second opportunity begins with a de-orbit burn at 6:17 p.m. with a landing at 7:23 p.m.

However, the Florida weather forecast is not any better than Thursday's. For that reason, Entry Flight Director Richard Jones has decided to call up Edwards Air Force Base in California as an alternate landing site for Friday.

The first landing opportunity in California begins with a de-orbit burn at 7:47 p.m. with a landing at 8:53 p.m. The final landing opportunity of the day would start with a de-orbit burn at 9:23 p.m. ending with a landing at 10:28 p.m.

With no weather constraints or technical issues, Discovery is GO for launch!

With the launch team working no issues and the weather 60% go for launch, liftoff of discovery remains on schedule for 11:59 pm. There are no launch criteria violations at this time.

More later!
