It will have delivered the European Lab – Columbus (APM) to the station.. On the fourth spacewalk the astronauts removed the European FOC camera, aboard HST since launch in 1990, and replaced it with the new ACS (Advanced Camera for Surveys). Launch delayed from March 22, April 4. House Shuttle Atlantis entered an orbit of roughly 59 x 229 km x 51.6 deg at 2052 UTC, and separated from the Exterior Tank, ET-114. This was the first flight of Columbia since the launch of Chandra in 1999 following refurbishment. In the primary two spacewalks, two new solar arrays were put in, and the 2 previous arrays stowed on the RAC carrier. Bay 11: FSS (Flight Support System) – 2111 kg. The truss was to supply structural support for the station’s thermal management radiators, and brought the entire mass of the ISS to over 200 tons. STS-124 was to have flown ISS assembly mission ISS-1J/A. STS-121 was to have flown ISS Assembly mission ISS-9A.1, delivering the SPP with four Solar Arrays to the station, and have carried out a crew rotation.. Simplesat was small astronomical test satellite tv for pc ejected from a Gas Cannister in shuttle Discovery’s payload bay. Spacecraft: Simplesat. Decay Date: 2002-01-30 . Spacecraft: MEPSI. Decay Date: 2003-01-31 . Leonardo then carried again all the trash from the ISS back to the shuttle. MEPSI (Micro-Electromechanical-based mostly Picosat Satellite Inspection Experiment) consisted of two 1 kg boxes hooked up to one another by a 15-m tether. It consisted of an Equipment Lock for storage and the Crew Lock, based on the Shuttle airlock.
The six tonne Airlock consisted of two cylinders of four meters diameter and a complete size six meters. These had been used to attach it to the Destiny module- Airlock Spur. An exterior stowage platform was attached to Destiny and the External Stowage Platform and the PFCS Pump Flow Control System were added to the port aft trunnion on Future. It additionally carried two science racks: the MSG (Microgravity Science Glovebox) and Express-3, which would be installed on Destiny. The crew installed in the station two new science experiment racks that have been carried in the Leonardo container which was first lifted out of the shuttle and bolted to the Unity module. These early results suggest that “the surgically induced readjustment of the weight set level appears to be related to sweet taste,” the researchers state. It calso carried the DBA2 diode field meeting which managed the arrays, and a wire harness and containers related to the NICMOS cooling system.- Bay 7-8: SAC (Second Axial Carrier) – 2517 kg.
Also carried was a Spacehab/Energia unpressurized Integrated Cargo Carrier with LCA/MTSAS-A, RU, and PFCS. LMC, the Lightweight MPESS Carrier carried four canisters with supplies science and expertise experiments: SEM-12, G-785, G-064 and G-730. As well as, an adapter beam on the starboard sidewall carried G-221 and G-775, with materials science and biology experiments. Some low-value science experiments such as microgravity cell development studies inside the station. The SEM (Space Experiment Modules) are collections of high school experiments. The 6.Four m x 4.6 m cylindrical MPLM was a descendant of the Spacelab lengthy modules. The S0 truss, constructed by Boeing/Huntington Beach, was 13.4 m long and 4.6 m in diameter. Later, it would be the positioning for the main Station truss, beginning with segment S0. The main truss had a hexagonal cross section. Atlantis docked with the International Space Station at 0308 GMT on July 14. The principle payload on STS-104 was the Quest Joint Airlock, constructed by Boeing/Huntsville. 2001 July 12 – . The STS-104 crew returned to Atlantis on July 22, and undocked at 0455 GMT. Atlantis fired its OMS engines at apogee to lift its perigee to 155 km. At 2259 GMT it fired its OMS engines to raise perigee to 225 km.
Carried out the OMS-2 burn to raise the orbit to 158 x 235 km. The OMS engines fired for the deorbit burn at 0625 GMT on March 21, and Discovery touched down on runway 15 at Kennedy Space Center at 0731 GMT. Discovery landed at Kennedy Space Center at 1822:58 GMT on August 22 on runway 15, after a deorbit burn at 1715 GMT. Raffaello was then unberthed from Unity at 2003 GMT on April 27 and reberthed within the rear of Endeavour’s bay for return to earth at 2059 GMT.Undocking of Endeavour was delayed by a series of computer problems on the Station. The Starshine-2 reflector satellite tv for pc was ejected from the MACH-1 bridge in Endeavour’s payload bay at 1502 UTC on December 16. Endeavour landed on runway 15 at Kennedy Space Center at 1755 UTC on December 17. The Expedition 3 crew of Culbertson, Dezhurov and Tyurin returned to Earth aboard Endeavour, leaving the Expedition 4 crew of Onufrienko, Bursch and Walz in command of the Station. Leonardo was docked to Unity at -Z for a while so that its cargo could be transferred to the station simply; it was then be returned to the payload bay and introduced back to earth.
