Crew: Halsell, Helms, Horowitz, Usachyov, Voss, Weber, Williams Jeffrey. First flight with new 'glass cockpit'. ISS Logistics flight. Repair, resupply and construction tasks aboard the international space station.

ISS Logistics flight. Launch delayed three times by weather. Objective of mission STS-101 was repair, resupply and construction tasks aboard the international space station. This was the first launch with new electronic cockpit displays and other upgrades. The solid boosters separated at 10:13 GMT and the main engines cutoff at 10:19 GMT. The external tank, ET-102 then separated, with both orbiter and ET-102 in a 52 x 320 km initial orbit. At 10:54 GMT the OMS engines fired to raise perigee to 159 x 329 km x at 51.6 deg. Atlantis docked with the International Space Station's PMA-2 docking adapter on the Unity node at 04:31 GMT on May 21. At that time the ISS was in a 332 x 341 km orbit.

On May 22 mission specialists Jeff Williams and James carried out external maintenance work on the ISS.

On May 23 at 00:03 GMT the Atlantis crew opened the first hatch to PMA-2 and entered the Station. The crew replaced a set of batteries in Zarya, installed fans and ducting to improve airflow, and delivered supplies and equipment. Three hour-long orbit raising burns on May 24 and 25 by the RCS engines on Atlantis raised the station to a 372 x 380 km x 51.6 deg orbit.

The STS-101 crew left the station on May 26, closing the PMA-2 hatch at 08:08 GMT and undocking at 23:03 GMT. Atlantis performed a 180 degree flyaround of the station and departed the vicinity around 23:44 GMT.

Atlantis closed its payload bay doors around 02:30 GMT on May 29 and fired the OMS engines for deorbit at 05:12 GMT. The vehicle landed on RW15 at Kennedy Space Center at 06:20 GMT. Atlantis was to be turned around for the next ISS shuttle flight, STS-106.

Left in orbit was the renovated International Space Station, equipped with an upgraded electrical system, new fans, filters, fire extinguishers, smoke detectors and communications gear.

Launch Highlights

After three launch delays in April caused by high winds at the launch site and overseas emergency landing strips, Atlantis blasted off from KSC's Launch Pad 39A on time. A crew of six American astronauts and one Russian cosmonaut were on their way to pay a "home improvement" house call on the fledgling International Space Station (ISS).

Mission Highlights

On their 10-day mission, the astronauts completed one space walk (EVA), equipped the ISS with new or replacement gear and transferred more than a ton of supplies into the space station for use by future residents of the ISS.

The EVA marked the fifth space walk for construction of the ISS, the 49th conducted from a space shuttle, and the 85th overall conducted by U.S. astronauts. During the six-hour, 44-minute EVA, Mission Specialists James Voss and Jeffrey Williams secured a United States-built crane installed on the station last year; installed the final parts of a Russian-built crane, Strela, on the Pressurized Mating Adapter-1 that connects the Unity node to the Zarya control module; replaced a faulty antenna for one of the station's communications systems; and installed several handrails and a camera cable on the ISS exterior. Mission Specialist Mary Ellen Weber operated the Shuttle's robotic arm, which she used to maneuver Voss during much of the space walk.

Work inside the space station followed. Before entering the space station, the crew opened various hatches into and within the different modules, in this order: PMA-2, Unity node, PMA-1, Zarya, and instrumentation cargo compartment on Zarya. Over the course of three days, the crew installed four batteries and associated electronics; 10 new smoke detectors in the Zarya module; four new cooling fans; additional cables for the Zarya computer to enhance capabilities; a new communications memory unit; and a new power distribution box for the U.S.-built communications system.

Next came the transfer of supplies more than 3,300 pounds of gear ranging from clothes, tools, can openers, sewing kits and trash bags to a treadmill, an exercise bicycle ergometer and IMAX film camera. The crew also filled four 12-gallon water containers for use by future resident astronauts aboard the ISS.

During the mission, Commander Halsell and Pilot Horowitz also fired Atlantis' jets three times to boost the ISS about 27 miles into a slightly higher orbit of 225 miles. When stowage was complete, the crew reversed the procedure to close the hatches in the space sttation, with the final hatch shut at 4:40 a.m. EDT, May 26.

Undocking with the space station occurred at 7:02 p.m. EDT, May 26. Pilot Horowitz backed Atlantis away and then flew a half-circle around the station before firing Atlantis' jets in a final separation burn at 7:41 p.m. EDT.

The priorities for STS-101/2A.2a were:

1. ISS ingress/safety - Take air samples - Monitor carbon dioxide - Deploy portable, personal fans - Measure air flow - Rework/modify ISS ducting - Replace air filters - Replace Zarya fire extinguishers, smoke detectors

2. Critical replacements/repairs/spares - Replace four suspect batteries on Zarya - Replaced failed or suspect electronics for Zarya's batteries - Replace Radio Telemetry System memory unit - Replace port early communications antenna - Replace Radio Frequency Power Distribution Box - Clear Space Vision System target

3. Incremental assembly/upgrades - Complete assembly of Strela crane - Install additional exterior handrails - Set up center-line camera cable - Install "Komparus" cable inserts - Reseat the U.S. crane

4. Assembly parts & equipment - Transfer U.S. hardware - Transfer Russian hardware - Provide EVA tools - Supply IVA kit

5. Pre-position/stow equipment & provisions for future missions

6. Resupply - Water and water transfer, stowage equipment - Docking mechanism accessory kit - Film and video tape for documentation - Office supplies - Personal items

7. Crew health maintenance - Exercise equipment - Medical support supplies - Formaldehyde monitor kit - Passive dosimetry system

8. Detailed test objectives - Monitor cabin air - SOAR

Trivia: This mission was originally scheduled to be launched in March of 2000. But delays with the Service Module for the International Space Station led NASA to split STS-101 into two missions. Three crew were transferred to STS-106, while the second ISS resident crew was added to STS-101. The crew of STS-101 would be: Commander; James Halsell, Pilot; Scott Horowitz and Mission Specialists, Ed Lu, Yuri Malenchencko, Boris Marukov, Mary Ellen Weber and Jeffrey Williams.

AKA: Atlantis; ISS-2A.2a.
First Launch: 2000.05.19.
Last Launch: 2000.05.29.
Duration: 9.84 days.
