The orbiter Atlantis is scheduled to land at Kennedy Space Center on
Monday, May 29, at about 2:20 a.m. EDT completing its near 10-day STS-101
mission that was launched from KSC May 19, 2000.

Landing at KSC’s Shuttle Landing Facility (SLF) is slated to occur
on orbit 156 at mission elapsed time 9 days, 20 hours, 9 minutes. Deorbit
burn will occur at about 1:16 a.m. EDT.

Two KSC landing opportunities Monday are: 2:20 a.m. and 3:56 a.m.

Managers have decided not to call up the back-up landing
location at Edwards Air Force Base (EAFB), CA, for a possible landing there
on Monday.

If managers must keep Atlantis in orbit an additional day,
two landing opportunities are available Tuesday at KSC and two at EAFB.

KSC Tuesday landing times are: 1:16 a.m. and 2:51 a.m. EDT.

EAFB Tuesday landing times are: 4:22 a.m. and 5:58 a.m. EDT.

This landing of Atlantis will mark the 51st landing at KSC
in the history of Space Shuttle flight. It will be the 22nd consecutive
landing at KSC and the 29th in the last 30 Shuttle flights. Atlantis is
currently on the 98th Space Shuttle mission in the history of the program.

SLF and KSC Ground Operations

The Shuttle Landing Facility was built in 1975. It is 300 feet wide
and 15,000 feet long with 1,000-foot overruns at each end. The strip runs
northwest to southeast and is located about 3 miles northwest of the
525-foot tall Vehicle Assembly Building.

Once the orbiter is on the ground, safing operations will commence
and the flight crew will prepare the vehicle for post-landing operations.
The Crew Transport Vehicle (CTV) will be used to assist the crew, allowing
them to leave the vehicle and remove their launch and re-entry suits easier
and quicker.

The CTV and other KSC landing convoy operations have been “on-call”
since the launch of Atlantis May 19. The primary functions of the Space
Shuttle recovery convoy are to provide immediate service to the orbiter
after landing, assist crew egress, and prepare the orbiter for towing to the
Orbiter Processing Facility.

Convoy vehicles are stationed at the SLF’s mid-point. About two
hours prior to landing, convoy personnel will don SCAPE suits, or
Self-Contained Atmospheric Protective Ensemble, and communications checks
are made. A warming-up of coolant and purge equipment is conducted and
nearly two dozen convoy vehicles are positioned to move onto the runway as
quickly and as safely as possible once the orbiter coasts to a stop. When
the vehicle is deemed safe of all potential explosive hazards and toxic
gases, the purge and coolant umbilical access vehicles move into position at
the rear of the orbiter.

Following purge and coolant operations, flight crew egress
preparations will begin and the CTV will be moved into position at the crew
access hatch located on the orbiter’s port side. A physician will board the
Shuttle and conduct a brief preliminary examination of the astronauts. The
crew will then make preparations to leave the vehicle.

Following departure from the SLF, the crew will be taken to their
quarters in the O&C Building, meet with their families and undergo physical
examinations. The crew is scheduled to depart for JSC later in the day

If Atlantis lands at Edwards, an augmented KSC convoy team will be
on-site to safe the vehicle, disembark the crew and move the orbiter to the
Mate/Demate Device. The turnaround team will be deployed to Edwards by
charter aircraft on landing day.

About 3* hours after Atlantis lands at KSC, the orbiter will be
towed to the Orbiter Processing Facility for post-flight deservicing.
