Astronauts From U.S. And Russia Make Emergency Landing After Booster Rocket Failure
A Russian Soyuz FG rocket carrying a veteran cosmonaut and a NASA astronaut on his first space flight blasted off from the Baikonur Cosmodrome in Kazakhstan on Thursday for a trip to the International Space Station, but the booster suffered an apparent failure shortly after liftoff, triggering an emergency abort and descent to Earth.
NASA commentator Brandi Dean in NASA mission control at the Johnson Space Center in Houston reported the Soyuz MS-10 capsule had made an emergency landing after a "ballistic" descent, a normal but steeper-than-usual trajectory back to Earth. Dean said the Soyuz descent module landed near the town of Dzhezkazgan, Kazakhstan, a familiar staging point for support personnel in normal Soyuz re-entries from space. Dean reported recovery crews were in radio contact with Ovchinin and Hague and that both crew members were in good condition.
She said that while the Soyuz crew would have been "subjected to higher G-forces" during to the ballistic descent, it is a "known mode of descent" that the crew would have been versed in.
A problem with the Soyuz MS-10/56S's booster was behind the aborted mission, Dean said from Johnson Space Center. The crew reported at one point, relayed through a Russian translator, they were weightless as the capsule flew free on its own.
A Russian "state commission" has been formed to investigate the mishap. Dmitri Rogozin, director general of the Russian space agency Roscosmos, said in a tweet "the Soyuz MS emergency rescue system worked. The crew is saved."
Air-to-ground communications with the crew were cut off, either because NASA or the Russian space agency opted to keep the loop private or because of a malfunction during the rapid descent.
Search and rescue crews have deployed to the Soyuz landing site and are in contact with the two crew members, one America and one Russian, who are in good condition. We await further word from the search and rescue team. Latest updates: https://t.co/mzKW5uDsTi pic.twitter.com/iztvONjyVx— NASA (@NASA) October 11, 2018
Veteran cosmonaut Alexey Ovchin was strapped into the central crew module's center seat, flanked on the left by flight engineer and co-pilot Nick Hague, a NASA astronaut making his first flight.
This was the first launch mishap for a Russian Soyuz booster since an on-pad abort in August 1983 that subjected two crew members to 17 times the force of gravity as the capsule was pulled away from an exploding booster. An earlier abort forced a different crew to land in Mongolia in 1975.
The only fatalities in the Russian manned space program occurred during re-entries from orbit. Cosmonaut Vladimir Komarov was killed in 1967 when the parachutes in his malfunctioning capsule failed to inflate. Three cosmonauts -- Vladislav Volkov, Georgi Dobrovoiski and Viktor Patsayev -- lost their lives in 1971 when their Soyuz depressurized during descent.
The Russians have experienced upper stage failures in a variety of unpiloted missions, but the two launch aborts 35 and 43 years ago are the only such launch mishaps in the history of the Russian human space program.
Thursday's mission began with an on-time liftoff at 4:40 a.m. EDT (GMT-4; 2:40 p.m. local time). Climbing to the east under a clear sky, the Soyuz put on a spectacular show as it smoothly accelerated toward space atop a long jet of brilliant flame from its central core stage and four liquid-fueled strap-on boosters.
Live television views from inside the crew module showed Ovchinin and Hague calmly monitoring cockpit displays as they were pushed back into their seats by the steady acceleration.
The four strap-on boosters were jettisoned as planned shortly after liftoff and the flight was proceeding under the power of its second stage core booster when the mishap occurred.
The Russians routinely practice ascent abort procedures and the Soyuz is equipped with multiple systems to assure a safe landing at virtually any point during the climb to space. But unlike a normal landing, recovery crews are not stationed downrange ahead of the emergency landing.
