Duque spent 10 days in space, having flown up to the International Space Station with the Expedition Eight crew, who are to spend the next six to seven months aboard the orbital outpost.Recovery forces met the crew and extracted them from the capsule. NASA officials who are part of the recovery force report that the just-returned crew is in good shape.
The trio's touchdown came in an open area on the steppes of Kazakhstan, where they were greeted by technicians and officials converging on the spot in helicopters and all-terrain vehicles.
Helicopters spotted the scorched capsule a few minutes before the touchdown, hanging beneath its primary parachute. Radio contact also was made with the crew before the landing.
The landing sequence began earlier today when the two crews said their farewells and hatches were closed, leading to undocking of the Soyuz TMA-2 from the space station at 6:17 p.m. EST (2317 GMT). The de-orbit burn then began as scheduled at 8:47 p.m. EST (0147 GMT Tuesday) and lasted for four minutes and 17 seconds.
All went well during re-entry.
Officials at Mission Control outside Moscow and others waiting in Kazakhstan for the landing were pleased that the wild ride of the last Soyuz descent in May, which ended with the American and Russian crew going some 250 miles off-course due to a computer error, was avoided.
Russian aerospace engineers had said there was only a slim chance that this crew would suffer from the same computer malfunction that sent the station's previous inhabitants on such a steep trajectory home that their tongues rolled back in their mouths. The May landing was so far off-target that more than two gut-wrenching hours passed before rescuers knew the men were safe.
``There is very little probability of another ballistic landing,'' said Gen. Vladimir Popov, who heads the team responsible for Russia's space search and rescue operations. ``But we must be prepared for any variant, and we are.''
Kazakhstan, where the Russian manned space program also has its launch pad, agreed to a Russian request to close off a wider swath of airspace than previously, said Mikhail Zotov, the search and rescue spokesman. Rescue crews were to fly from three locations instead of one to cover all the possible landing spots, he said.
Thirteen helicopters, four planes and numerous off-terrain vehicles were to take part in the operation. The search teams will include flight surgeons from NASA and the European Space Agency.
Additionally, this Soyuz was equipped with satellite phones and a global positioning satellite system _ courtesy of NASA _ so if the crew had landed off-course and communications systems are damaged as happened in May, they would still have been able to determine and phone in their location.
The May landing rattled Russian space officials and NASA, which had sent their top administrators to Mission Control outside of Moscow to monitor the maiden return of the new model Soyuz with its first-ever U.S. and Russian crew. It came just three months after Columbia broke apart during re-entry, killing all seven astronauts.
Russian aerospace engineers made minor adjustments to the Soyuz that blasted off Oct. 18, but the Soyuz that came home Tuesday was already docked in space so no changes were made.
``This Soyuz is still technically susceptible to the same type of problem but the Russians believe they understand it well enough and they've trained the crew ... so they can possibly do something manually to override the computer,'' NASA spokesman Rob Navias said in Astana, Kazakhstan's capital.
About three hours before departure, Lu, Malenchenko and Duque bid farewell to the station's new crew, American Michael Foale and Russian Alexander Kaleri.
Malenchenko returned to Earth a married man, having married Texas resident Ekaterina Dmitriev by proxy while in space. The new bride was waiting at a military air base near Star City outside Moscow, where the cosmonauts were to be flown later Tuesday.
Also waiting were NASA scientists, eager for water samples and, if there is room, a canister of air from the space station. Monitoring equipment onboard has broken down, leading some NASA officials to reportedly express concerns about keeping crews up there. NASA, along with astronaut Foale, have dismissed the fears, saying there are no indications of a health risk.
