Launch from the Baikonur Cosmodrome. Landing
				  152 km southeast of Dzheskasgan.
ISS
				  Expedition 35 /
				  36. 
				  Following a only six-hours solo flight
				  
Soyuz TMA-08M docked to
				  
ISS on March 29, 2013. Pavel
				  
Vinogradov, Aleksandr
				  
Misurkin and Christopher
				  
Cassidy became the
				  
ISS
				  Expedition 35
				  (together with
				  
ISS
				  Expedition 34 crew
				  members Roman
				  
Romanenko, Chris
				  
Hadfield and Thomas
				  
Marshburn). It was the shortest time from launch to
				  docking.
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 286 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.
