Launch of a Russian Soyuz rocket carrying a cosmonaut commander, a guest flier from Belarus and NASA astronaut Tracy Dyson was aborted at the T-minus 20-second mark Thursday, delaying the crew’s planned flight to the International Space Station.
With veteran commander Oleg Novitskiy at the controls, flanked on the left by Belarus spaceflight participant Marina Vasilevskaya and on the right by NASA veteran Tracy Dyson, the countdown was ticking smoothly toward liftoff at 9:21 a.m. EDT when an unidentified controller called an abort.
No explanation was immediately provided, but NASA’s launch commentator said the crew was safe and the rocket was in a stable configuration as ground crews began re-erecting launch pad gantries to gain access and to help Novitskiy, Vasilevskaya and Dyson out of the Soyuz MS-25/71S spacecraft at the top of the booster.
NASA commentator Rob Navias in mission control at the Johnson Space Center in Houston said the next launch opportunity is Saturday, which would set up a docking at the space station Monday. But he said that would depend on the nature of the problem that triggered the abort and what might be required to fix it.
Flight controllers in Houston told the space station crew the Soyuz launch had been aborted and that its crew was safe, ending with “it’s going to be a few days before you guys have visitors up there.”
In the meantime, SpaceX engineers pressed ahead with work to ready a Falcon 9 rocket for launch from Cape Canaveral at 4:55 p.m. EDT to send a Dragon cargo ship to the station loaded with 6,200 pounds of science gear, spare parts and crew supplies.
The flight plan called for the Cargo Dragon to catch up with the station and to move in for docking early Saturday.
Whenever they get off, Novitskiy, Vasilevskaya and Dyson will be joining ISS commander Oleg Kononenko, cosmonauts Nikolai Chub and Alexander Grebenkin and NASA astronauts Loral O’Hara, Matthew Dominick, Michael Barratt and Jeanette Epps.
Vasilevskaya, an accomplished ballroom dancer and flight attendant with Belavia Airlines, is the first citizen of Belarus, a staunch ally of Russia, to be named to a spaceflight since the breakup of the Soviet Union. She was selected as a “spaceflight participant” in a nationwide competition and will conduct research for scientists in Belarus.
“I’m so proud to represent our republic, I’m so proud we have this project,” she said before boarding the Soyuz for launch.”
Dyson is making her third spaceflight and her second aboard a Soyuz. Despite tension between the United States and Russia, the crew appears to get along well together.
“It’s actually been a real delight working with Marina,” Dyson said. “She’s got a fantastic attitude, and that goes a long way when you’re working together with emergency masks on your face in awful conditions trying to get through (emergency training) procedures. She’s been a real delight to work with.”
Kononenko, Chub and O’Hara were launched to the station last Sept. 15 aboard the Soyuz MS-24/70S spacecraft. Dominick, Barratt, Epps and Grebenkin were launched on March 3 aboard a SpaceX Crew Dragon ferry ship. Known as Crew 8, they replaced four other Crew Dragon fliers — Crew 7 — who returned to Earth on March 12 after a short handover.
Novitskiy and Vasilevskaya plan to spend 12 days aboard the space station. O’Hara will replace Dyson for the trip home and the trio will return to Earth aboard the Soyuz MS-24/70S spacecraft that carried O’Hara, Kononenko and Chub into orbit last September.
Kononenko and Chub are midway through a planned yearlong stay aboard the station. If all goes well, they will return to Earth next September, along with Dyson, using the Soyuz MS-25/71S ferry ship delivered by Novitskiy’s crew. With O’Hara’s return, the latest crew rotation sequence will be complete.
