Shuttle and Stations

--------------------



Atlantis docked to ISS Alpha on Feb 9. At 1500 UTC on Feb 10 Marsha

Ivins used the RMS arm to unberth the PMA-2 docking port from Unity. Tom

Jones and Bob Curbeam have begun the first spacewalk from the ODS

airlock on Atlantis, supervising the assembly operations. The airlock

was depressurized at 1544 UTC; the hatch was opened at 1546 UTC and the

astronauts went to suit battery power at 1550 UTC. PMA-2 was berthed on

Z1 at 1650 UTC; Destiny was unberthed from the payload bay at 1735 UTC

and docked to Unity at 1900 UTC.  At 1935 UTC Curbeam was connecting

ammonia coolant lines when a leaking connector sprayed ammonia into

space, contaminating his suit. He was ordered to stay in sunlight to

bake off the ammonia. At around 2311 UTC the spacewalkers returned to

the airlock, closing the hatch at 2318 UTC. Repressurization began at

2324 UTC, for a duration of 7h40m (depress), 7h34m (NASA), or 7h32m

(hatch open/close). 



The airlock reached 5psi (34 kPa) at 2326 UTC and was held there, with

the astronauts still in suits. A new depressurization for

decontamination was begun at 2342 UTC, with the airlock fully

depressurized at 2350 UTC. The hatch was then opened and closed quickly

at 2351-2352 UTC, to flush the airlock of any ammonia residue, and

repressurization began anew at 2353 UTC, reaching 5psi again prior to

2357 UTC. This new spacewalk lasted 3 minutes (depress), or 1 minute

(hatch open/close); it was not counted as an EVA by NASA.



EVA-2 began at 1555 UTC on Feb 12 with depressurization of the airlock.

The astronauts went to battery power at 1559 UTC. The PMA-2 docking port

was attached to Destiny at 1728 UTC. The Power Data Grapple Fixture

(PDGF) was removed from its location on an adaptive payload carrier on

the port side of the payload bay (probably bay 5P) and installed on

Destiny. The PDGF will be used by the Station's robot arm, and is an

improved grapple fixture with electrical power and data ports. The hatch

was closed at 2240 UTC and the  airlock was repressurized at 2249 UTC.

Duration was 6h54m (depress), about 6h50m (hatch open/close), or

6h50m (NASA rule).





The third official EVA was on Feb 14. The airlock was depressurized at

1443 UTC, with hatch open at around 1445 and battery power at 1448. The

spare SASA S-band antenna was unberthed from an adapter beam in the

payload bay  (around bay 4P?) and installed on Z1. The +X (starboard)

TCS radiator on P6, launched on the previous mission, was deployed at

1649 UTC. The astronauts completed the spacewalk with repressurization

of the airlock at 2013 UTC. Time was 5h30m (depress), about 5h24m (hatch

open/close), or 5h25m (NASA).



Atlantis undocked from Alpha at 1406 UTC on Feb 16.

Landing was waved off on Feb 18 and is expected on Feb 19.



Destiny has been cataloged by US Space Command as 2001-06B (SSN 26700).

Unity was also given a catalog number, but for some reason Z1 and P6

were not. 



At the end of the docked phase, Atlantis mass is 95242 kg and

the Station mass is 104401 kg for a total mass of 199643 kg.
