Flight

Launch from the Baikonur Cosmodrome; landing 338 km west of the intended site in Kazakhstan due of a ballistic descent.

Charles Simonyi was another space tourist. This mission was the ISS Expedition 15. Following a two day solo flight Soyuz TMA-10 docked with the ISS on April 09, 2007. Oleg Kotov and Fyodor Yurchikhin replaced the Expedition 14 crew.

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.
Having shed two-thirds of its mass, the Soyuz reached Entry Interface - a point 400,000 feet 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 per second. Before it touched down, its speed slowed to only 5 feet 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 per second to 262 feet per second.
The main parachute was the last to emerge. It is the largest chute, with a surface area of 10,764 square feet. 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 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.

The landing occurred in an unexpected ballistic descent to Earth (for the first time since Soyuz TMA-1). So the landing was one minute earlier than planned, harder (up to 9g, normal 4g) and about 300 kilometers short from the target landing point, but the crew was in good condition and safe.

Note

Charles Simonyi landed on April 21, 2007 at 12:31 UTC with Soyuz TMA-9 spacecraft.
