for-all-mankind:Soyuz MS-10 experiences launch anomaly; crew aborts to safe landing.One of Russia’s most reliable launchers experienced a rare, in-flight anomaly earlier this morning, forcing the two-man crew of Soyuz MS-10 to abort the mission.Following a normal liftoff at 4:40am EST (2:40pm local time), a malfunction in the Soyuz FG rocket two minutes into the flight forced Expedition 57 crewmembers Alexey Ovchinin and Nick Hague to abort a manual abort profile. The anomaly occurred immediately following the separation of the rocket’s four strap-on boosters and jettisoning of the Launch Escape System. However, the protective fairing covering the spacecraft during flight through the thick atmosphere was still on, and solid rocket motors attached to the fairing pulled the crew capsule away from the failing booster.Following a ballistic trajectory through the upper atmosphere, the Soyuz’s Descent module separated from the Orbital Module and payload fairing and descended to a safe landing 20 kilometers east of Zezkezhan, Kazakhstan, 34 minutes after launch. Roscosmos reported that the crewmembers experienced around seven times the force of gravity, or 7G’s, during their abort. Recovery forces reached the landing site immediately following touchdown. Both astronauts were reported to be in good health following their ordeal, and returned to their families at the Baikonur launch site around six hours after liftoff.Recovery forces at the Soyuz MS-10 emergency landing site.

While no cause of the mishap is currently known, Russian authorities have begun an investigation of the incident and have temporarily grounded all future Soyuz flights. The current three-member crew of Expedition 57 is slated to return to Earth December 13, followed by the launch of Expedition 58 December 20. Following today’s anomaly, it is unclear whether Expedition 57 will remain on orbit longer, or when the next crew will launch to the station. Expedition 57 is able to remain on orbit until early January, when their Soyuz reaches its certified orbital lifetime.Expedition 57 commander Alexander Gerst captured this image of the Soyuz MS-10 launch from the International Space Station. The anomalous nature of the launch is evidenced by multiple points of light along the ascent path. Source: NASA.Watch NASA TV coverage of the Soyuz MS-10 launch below.P/c: NASA. -- source link
