Just 5 minutes now till the lift off of #SoyuzMS10 carrying Astronaut @AstroHague and Cosmonaut Alexey Ovchinin to the @Space_Station. You can watch the launch live at
Lift off for #SoyuzMS10 from Baikonur. Now on its way to the #ISS.
There has been "an issue" with the #SoyuzMS10 booster. No further information at this time.
"Today's SoyuzMS10 launch went into ballistic trajectory mode. The crew will not be going to the #iSS today, instead they'll be taking a ballistic trajectory and landing." …standing by for more information.
As you'd expect in this situation @Roscosmos have cut their feed, we only have a mostly silent view of the @NASA's MCC at Houston. No confirmed word on the crew yet. #SoyuzMS10 is returning to Earth in a ballistic abort mode. Crew will be undergoing very high G forces.
This is not the only time this sort of abort has happened with a Soyuz, but this failure mode is vanishing rare. The Soyuz is one of the most dependable work horses of spaceflight. #SoyuzMS10
"Search and rescue teams are already on their way to the area where the crew is expected to land, it will take them about an hour and a half to reach that area however…" no official word yet on the fate of the crew. #SoyuzMS10 #ISS
Potentially a good 'chute for #SoyuzMS10 decent module. No official confirmation at this time.
This is Russia state media, so don't take this as a confirmation that the crew is safe. However it's a good sign. #SoyuzMS10 #ISS
Current summary of what we know from @NASA. You can follow live at #SoyuzMS10 #ISS
"We are in communication with the crew at this point, and are hearing that they are in good condition…" @NASA is reporting that @Roscosmos is telling them that rescue forces are in contact with the crew. #SoyuzMS10 #ISS
Rescue helicopters took off at 03:51 CDT. They've been in the air just over half an hour, potentially still up to an hour to reach the #Soyuz landing site. #SoyuzMS10 #ISS
Several reports now that the landing site of the #SoyuzMS10 decent module is near the Kazakhstan town of Zhezqazghan.
Reuters is reporting that the Search & Rescue forces have reached the capsule. No official confirmation of this from NASA. #SoyuzMS10 #ISS
This definitely doesn't look like a nominal booster seperation. #SoyuzMS10 #ISS
Today's #SoyuzMS10 failure has serious implications. Likely the Soyuz, only way to get astronauts to and from the @Space_Station, will be grounded indefinitely, and we're at least a year away from a crewed launch from either #SpaceX or #Boeing under the #CommercialCrew program.
The first crewed test flight for #SpaceX isn't scheduled till June next year, while the #Boeing test flight was scheduled for August but rumour suggests that the schedule has already slipped. Today's #SoyuzMS10 failure may mean that the #ISS could have to be abandoned for a time.
"…now have reports that the search and rescue teams have reached the landing site, and the crew is out of the capsule. Crew reported in good condition. Recovery teams are with them and working to get them ready to leave." #NASA #Roscosmos #SoyuzMS10 #ISS
Looking again at booster separation. Here's a nominal separation (top) taken from a previous launch, with today's #SoyuzMS10 separation (bottom) for comparison. Asymmetrical separation with obvious debris falling.
"Hearing that crew members are onboard helicopters and are enroute back to the Baikonur cosmodrome at this point…" #SoyuzMS10 #ISS
Audio of conversation between #NASA capcom and the crew onboard the #ISS informing them of the safe landing of the #SoyuzMS10 crew. The conversation that took place just after 5am CDT this morning.…
Roscosmos has released imagery of the #SoyuzMS10 crew members on the ground before they embarked onto helicopters back to Balkinour.
May be the first images we have from #SoyuzMS10 emergency landing site? Hard to tell due to resolution, unconfirmed by @NASA or @Roscosmos at this time.
"…a state commission was formed by my decision. She has already begun work. Telemetry is being studied," says @Rogozin, .
Depending on what the Russian investigation uncovers an unmanned Soyuz could be send up to replace the craft currently docked with the #ISS which has a limited lifespan on-orbit. Doubtful a crewed Soyuz launch could happen soon enough. #SoyuzMS10
Looking at the footage again from the launch, this sounds like a potentially reasonable explanation. But obviously a lot of work to be done to confirm this. #SoyuzMS10
So the current limiting factor to whether crew can remain on the #ISS is the lifespan of the #Soyuz currently docked to the station in orbit. They must return before April 2019 even if crewed flights have not resumed. #SoyuzMS10
