Discovery Prepares for Tuesday Landing

From NASA:

Mon, 19 Apr 2010 08:59:09 PM PDT

At 10:21 p.m., mission control played “On the Road Again” by Willie Nelson as the wakeup call for Commander Alan G. Poindexter, Pilot James P. Dutton Jr. and Mission Specialists Dorothy Metcalf-Lindenburger, Rick Mastracchio, Stephanie Wilson, Clayton Anderson and Japanese astronaut Naoko Yamazaki.

Space shuttle Discovery’s crew is prepared to return home Tuesday, as mission managers closely monitor weather that could affect their entry and landing at the Kennedy Space Center in Florida.

The first Kennedy opportunity Tuesday would see a deorbit burn at 5:28 a.m. with a landing at 6:34 a.m. For the second opportunity the deorbit burn at 7:02 a.m. would lead to a landing 8:08 a.m.

For Edwards, the first opportunity deorbit burn would be at 6:56 a.m. with landing at 8:01 a.m. The next would have a deorbit burn at 8:30 a.m. and a landing at 9:35 a.m. while the third would begin with a deorbit burn at 10:05 a.m. leading to a landing at 11:11 a.m.

STS-131 Set to Land Tuesday

After a Monday wave-off of both KSC landings for bad weather, STS-131 has several opportunities to land on Tuesday, starting early in the morning local time.

Weather permitting, Discovery is scheduled to land at Kennedy Space Center's shuttle landing facility Tuesday at 7:34 a.m., 40 minutes after sunrise. The second landing opportunity at Kennedy is at 9:08 a.m.  Edwards Air Force Base in California is expected to be called up as a possible landing site. The first landing opportunity at Edwards is at 9:01 a.m.

All of the KSC opportunities are on descending paths over much of the continental US, allowing many people an opportunity to see a pretty spectacular re-entry in a dark or early morning sky.  The Edwards opportunities go right down the West Coast, and may do similar.  The rain storm that is moving into California should not affect Edwards in this time frame.

Check web sites for which orbit will actually have a landing.  Also, a table of passes for your US city can be generated by entering orbit number and KSC or EDW somewhere on NASA's site at spaceflight.nasa.gov.

STS-131 May Land Monday (If Weather Permits)

The first landing opportunity is on the KSC runway at 8:48 AM (1248 UTC).  If this landing happens, the ground track is different than usual, making the re-entry potentially visible to much of the continental US.

Unfortunately, the weather forecast is for conditions violating several constraints.  Another KSC opportunity exists Monday, and this one also uses the descending node track that would take it over the US.  If this is also waved off, STS-131 has several shots at KSC and Edwards on Tuesday.
