Spacecraft:  Soyuz TMA-2 (TMA No. 212)


Launch from the Baikonur Cosmodrome and landing 34 km southeast of Arkalyk in Kazakhstan.

This spaceflight became the ISS Expedition 7. The mission was called a "caretaker" crew. Following a two-day solo flight Soyuz TMA-2 docked to ISS on April 28, 2003. Yuri Malenchenko and Edward Lu replaced the Expedition 6 crew.

Due to the reduced crew size, the scientific work had to be scaled down as well. Only 15 different experiments were conducted during the mission. Yuri Malenchenko and Edward Lu were also tasked with periodic maintenance work on the station, as well as spacewalk training (although no spacewalks were planned.

Progress M1-10 was launched at 10:34 UTC on June 08, 2003. The spacecraft docked with the Pirs module at 11:14:53 UTC on June 11, 2003. Progress M1-10 carried supplies to the International Space Station, including food, water and oxygen for the crew and equipment for conducting scientific research. The freighter remained docked for three months before undocking at 19:41:44 UTC on September 04, 2003 to make way for Soyuz TMA-3. Following undocking, it remained in orbit for a month, conducting an earth observation mission. It was deorbited at 11:26 UTC on October 03, 2003, burning up in the atmosphere over the Pacific Ocean, with any remaining debris landing in the ocean at around 12:38:49 UTC.

Progress M-48, the next unmanned vessel, was launched at 01:47:59 UTC on August 29, 2003. The spacecraft docked with the Aft port of the Zvezda module at 03:40:45 UTC on August 31, 2003. Progress M-48 carried supplies to the International Space Station, including food, water and oxygen for the crew and equipment for conducting scientific research. The freighter remained docked for five months before undocking at 08:35:56 UTC on January 28, 2004 to make way for Progress M1-11. It was deorbited at 13:11 UTC on the same day. The spacecraft burned up in the atmosphere over the Pacific Ocean, with any remaining debris landing in the ocean at around 13:57:12 UTC.

The Soyuz spacecraft is composed of three elements attached end-to-end - the Orbital Module, the Descent Module and the Instrumentation/Propulsion Module. The crew occupied the central element, the Descent Module. The other two modules are jettisoned prior to re-entry. They burn up in the atmosphere, so only the Descent Module returned to Earth.
The deorbit burn lasted 256 seconds. Having shed two-thirds of its mass, the Soyuz reached Entry Interface - a point 400,000 feet (121.9 kilometers) above the Earth, where friction due to the thickening atmosphere began to heat its outer surfaces. With only 23 minutes left before it lands on the grassy plains of central Asia, attention in the module turned to slowing its rate of descent.
Eight minutes later, the spacecraft was streaking through the sky at a rate of 755 feet (230 meters) per second. Before it touched down, its speed slowed to only 5 feet (1.5 meter) per second, and it lands at an even lower speed than that. Several onboard features ensure that the vehicle and crew land safely and in relative comfort.
Four parachutes, deployed 15 minutes before landing, dramatically slowed the vehicle's rate of descent. Two pilot parachutes were the first to be released, and a drogue chute attached to the second one followed immediately after. The drogue, measuring 24 square meters (258 square feet) in area, slowed the rate of descent from 755 feet (230 meters) per second to 262 feet (80 meters) per second.
The main parachute was the last to emerge. It is the largest chute, with a surface area of 10,764 square feet (1,000 square meters). Its harnesses shifted the vehicle's attitude to a 30-degree angle relative to the ground, dissipating heat, and then shifted it again to a straight vertical descent prior to landing.
The main chute slowed the Soyuz to a descent rate of only 24 feet (7.3 meters) per second, which is still too fast for a comfortable landing. One second before touchdown, two sets of three small engines on the bottom of the vehicle fired, slowing the vehicle to soften the landing.
