RSS Wrapped Around Atlantis, Endeavour Prepped for System Purge

At NASA Kennedy Space Center's Launch Pad 39A, teams have closed the rotating service structure (RSS) around space shuttle Atlantis. The RSS provides access to the shuttle and helps protect the spacecraft from the elements.

Engineers have reviewed data from a lightning strike nearly half a mile from the pad on Wednesday. No issues have been seen due to the strike. An engineering team also will perform a visual inspection walkdown at the pad.

Today, technicians will connect the forward reaction control system quick disconnects and check them for leaks, over the weekend, teams will connect and check the quick disconnects for the auxiliary power system.

Meanwhile, technicians in Kennedy's Orbiter Processing Facility-1 prepare Endeavour today for this weekend's purging of the vehicle's orbital maneuvering system chemicals.

RSS Closes Around Atlantis, Endeavour’s Retirement Processing Begins

At NASA Kennedy Space Center's Launch Pad 39A, teams closed the rotating service structure (RSS) this morning and will evaluate data from a storm that passed over Kennedy yesterday. A lightning strike was detected about half a mile from the pad. Teams will perform walkdowns and evaluate the data.

Meanwhile, technicians completed a hotfire of space shuttle Atlantis' auxiliary power unit and connected the ground umbilical carrier plate Wednesday.

At Kennedy's Orbiter Processing Facility-1, technicians will begin draining the residual cryogenic fuel from shuttle Endeavour's power reaction control distribution system today.

Endeavour Lands, Atlantis at Launch Pad

Space shuttle Endeavour landed for the final time at NASA’s Kennedy Space Center after 248 orbits around Earth and a journey of 6,510,221 miles on STS-134.

Endeavour’s main gear touched down at 2:34:51 a.m. followed by the nose gear at 2:35:04 and wheels stop at 2:35:36 a.m.

A post-landing news conference with managers at Kennedy is expected no earlier than 4:30 a.m. on NASA Television and http://www.nasa.gov/ntv. The participants will be Bill Gerstenmaier, associate administrator for Space Operations, Mike Moses, space shuttle launch integration manager, and Mike Leinbach, space shuttle launch director.

STS-134 was the 25th and final flight for Endeavour, which spent 299 days in space, orbited Earth 4,671 times and traveled 122,883,151 miles.

Meanwhile, space shuttle Atlantis just completed its 3.4 mile trek from the Vehicle Assembly Building to Launch Pad 39A. The spacecraft, external fuel tank and twin solid rocket boosters, attached on the mobile launcher platform were secured to the launch pad at 3:29 a.m. The move began last night at 8:42 p.m. and took approximately 7 hours.

Endeavour Lands For Final Time at 2:34 a.m. EDT

Space shuttle Endeavour landed for the final time at NASA’s Kennedy Space Center after 248 orbits around Earth and a journey of 6,510,221 miles on STS-134.

Space shuttle Atlantis now is about half way complete with its move from NASA Kennedy Space Center's Vehicle Assembly Building to Launch Pad 39A.

Currently, the crawler-transporter (CT) with Atlantis and its mobile launcher platform on top is temporarily stopped to allow technicians to preemptively grease some bearings in the CT that were starting to heat up. The rollout will resume shortly.

Atlantis is expected to be secured on the launch pad about 3:30 a.m. EDT.

Deorbit Burn Complete; Endeavour Headed to Kennedy Space Center

Space shuttle Endeavour has completed the deorbit burn, setting it on a course to return to Kennedy Space Center in Florida. Entry interface, the point at which the shuttle begins entering the Earth’s atmosphere, will occur at 2:03 a.m. EDT. Peak heating begins at 2:12 a.m., the first roll reversal to slow the spacecraft will take place at 2:16 a.m., and peak heating should end about 2:22 a.m.

Endeavour will head to the northeast across the west coast of Florida near Fort Meyers Beach, triggering dual sonic booms minutes later when it slows to subsonic speeds at about 2:31 a.m. Commander Mark Kelly will align Endeavour with Kennedy’s northwest to southeast runway 15 and touch down at 2:35:23 a.m.

Endeavour Given “Go” for Deorbit Burn

Mission Control Capcom Barry Wilmore gave space shuttle Endeavour Commander Mark Kelly a "go" for the deorbit burn. The shuttle’s two Orbital Maneuvering System (OMS) engines will fire at 1:29 a.m. EDT for two minutes, 38 seconds and slow Endeavour by 201 miles per hour. Landing is expected at 2:35 a.m. at NASA's Kennedy Space Center, runway 15.

You can track Endeavour during landing in Google Earth using real-time data from Mission Control: http://bit.ly/lw9VCg

Weather is observed and forecast “go.”

Endeavour’s Payload Bay Doors Are Closed for Landing

Space shuttle Endeavour’s payload bay doors are closed and everything continues to proceed on schedule for Wednesday morning’s landing attempt.

Weather is forecast and observed “go” and astronaut Rick Sturckow is flying weather reconnaissance at Kennedy Space Center to assess conditions for Endeavour’s landing.

At 10:59 p.m. Mission Control is expected to give a “go” for Endeavour’s computers to begin running the Ops 3 entry software. At 11:29 p.m. a “go” is expected for crew suit up. The “go” for deorbit burn is expected by 1:09 a.m. Wednesday.

The deorbit burn scheduled for 1:29:43 a.m. will lead to a landing at 2:35:23 a.m.

Space shuttle Atlantis now is moving out of Kennedy Space Center’s Vehicle Assembly Building headed for Launch Pad 39A. First motion was at 8:42 p.m. EDT.

Technicians repaired a minor hydraulic leak on a corner valve for the jacking and elevation system on the crawler-transporter, which delayed the scheduled 8 p.m. rollout start.
