Russian Soyuz rocket suffers rare last-minute abort during launch of 3 astronauts to ISS (video) – Space.com

Posted: March 24, 2024 at 4:42 pm

Update for 1 p.m. ET: The abort of today's Soyuz launch may have been due to a dead battery. "The reason has been identified, we just discovered at a meeting of the state commission that the reason was a voltage drop in the chemical current source," Roscosmos General Director Yuri Borisov said in a statement posted to the Russian space agency's Telegram account today.

A Russian Soyuz rocket carrying three astronauts bound for the International Space Station experienced a rare abort on the launch pad on Thursday (March 21) while the crew waited expectantly inside their spacecraft.

The abort occurred just 21 seconds before the Soyuz rocket was to launch NASA astronaut Tracy Caldwell Dyson, Russian cosmonaut Oleg Novitskiyand spaceflight participant Marina Vasilevskaya of Belarus to the International Space Station (ISS) from Baikonur Cosmodrome in Kazakhstan. Liftoff was scheduled for 9:21 a.m. EDT (1321 GMT).

"The Soyuz launch to the space station has been aborted," NASA spokesperson Rob Navias said during live commentary. "So, no visitors to the International Space Station today. The next opportunity to launch, pending resolution of what happened today, would be Saturday morning," he added.

Navias said the abort was triggered by an automatic system shortly before engine ignition; two umbilical connections were retracted away from the rocket ahead of the planned launch. Roscosmos, Russia's space agency, sent engineers to the launch pad shortly after the abort to make sure the vehicle was safe and crew could be extracted.

"The vehicle is safe, all fueling operations have ceased," Navias said. "All safety commands have been provided onboard the rocket so there's no danger to the crew. They're perfectly safe."

NASA's Mission Control center radioed news of the launch abort to astronauts aboard the ISS shortly after it occurred. Flight controllers made it clear the Soyuz crew was safe.

"Station copies; aborted," station commander Andreas Mogensen of the European Space Agency replied. "Most importantly, Station copies crew are safe."

Russia's Soyuz rockets and crewed Soyuz spacecraft are workhorse transport vehicles that regularly fly cosmonauts and astronauts to and from the ISS. Roscosmos has used the spacecraft for crewed flights throughout the 24-year history of the ISS, as well as during its previous Mir space station program.

An abort just before launch is exceedingly rare for Soyuz rockets. In October 2018, a Soyuz rocket carrying NASA astronaut Nick Hague and cosmonautAlexey Ovchinin suffered an in-flight abort that forced the crew's Soyuz capsule to rip free from its rocket and make a harrowing emergency landing. That abort was traced to a deformed sensor on the Soyuz rocket.

Dyson, Novitskiyand Vasilevskaya are set to launch on a mission to join the ongoing crew on the International Space Station. Dyson and Novitskiyplan to spend six months aboard the space station as part of its Expedition 71 crew, while Vasilevskaya is set to embark on a 12-day stay and return home with the outgoing Expedition 70 crew.

Exactly when the three space travelers will launch, however, is unclear. While Roscosmos has said the next window to launch the trio will open on Saturday, engineers with Soyuz rocket maker Energia will have to understand why today's Soyuz launch aborted and perform any fixes that may be required. NASA has pledged to share updates as they are received from Roscosmos and Energia.

Meanwhile, in Florida, another rocket is counting down to launch to the ISS today.

An uncrewed SpaceX Falcon 9 rocket and Dragon cargo ship are scheduled to launch more than 2 tons of fresh supplies to the ISS from Space Launch Complex 40 at the Cape Canaveral Space Force Station in Florida. Liftoff for that mission is scheduled for 4:55 p.m. EDT (2055 GMT) and should continue as planned, Navias said.

"The preliminary word is that the Falcon 9 launch of the CRS-30 resupply mission to the station will likely proceed as planned today," he added.

NASA and SpaceX will provide a livestream of the CRS-30 cargo launch, beginning at 4:35 p.m. EDT (2035 GMT).

Saturday's launch will kick off the third spaceflight for Dyson, the fourth for Novitskiy and the first for Vasilevskaya. The latter two spaceflyers will be in orbit for just 12 days or so; they'll come back to Earth in early April aboard a different Soyuz, along with NASA astronaut Loral O'Hara, who's wrapping up a 6.5-month stint on the ISS.

Dyson will live aboard the orbiting lab for six months, eventually coming home in September with Oleg Kononenko and Nikolai Chub of Roscosmos, who are conducting a yearlong mission on the ISS.

The Soyuz mission will be the second launch to the ISS in just a few days; SpaceX launched a robotic cargo mission to the station on Thursday at 4:55 p.m. EDT (2055 GMT).

Editor's note: This story was updated at 5:15 p.m. EDT on March 22 with the new target launch and docking dates of March 23 and March 25, respectively.

Soyuz launches to station after scrub – SpaceNews

Posted: at 4:42 pm

WASHINGTON A Soyuz spacecraft is en route to the International Space Station, two days after a rare last-minute launch scrub.

A Soyuz-2.1a rocket lifted off from the Baikonur Cosmodrome at 8:36 a.m. Eastern March 23. It placed the Soyuz MS-25 spacecraft into orbit about nine minutes later.

Soyuz MS-25 is commanded by Roscosmos cosmonaut Oleg Novitskiy with NASA astronaut Tracy C. Dyson and Marina Vasilevskaya, a Belarusian spaceflight participant, also on board. The spacecraft is scheduled to dock with the stations Prichal module at 11:09 a.m. Eastern March 25.

The launch was scheduled for March 21, but the countdown was halted just 20 seconds before liftoff. Roscosmos said several hours later that the launch was called off because of a low voltage reading in the launch vehicle. There had been no record of a scrub so late in the countdown of a crewed Soyuz launch before this incident.

At a March 22 briefing about the upcoming CST-100 Starliner crewed test flight to the station, Dana Weigel, NASA ISS deputy program manager, said at that time that Roscosmos was still troubleshooting the issue, but Roscosmos announced later in the day the launch had been rescheduled for the next day.

NASA spokesman Rob Navias said in NASA TV coverage of the second launch attempt that batteries were replaced and tested in the Soyuz rockets first stage after the scrub, allowing the launch to proceed.

The two-delay launch delay will mean a four-day delay in the arrival of the crew to the station. The original launch was planned to allow the Soyuz to fly a fast approach to the station, arriving about three hours after launch. That trajectory is not available on this launch attempt, meaning the crew will take a more conventional two-day approach to the station.

Once docked to the station, Novitskiy and Vasilevskaya will remain for 12 days, returning in the Soyuz MS-24 spacecraft currently there with NASA astronaut Loral OHara, who launched to the station in that spacecraft in September along with Russian cosmonauts Oleg Kononenko and Nikolai Chub. That departure is scheduled for April 6. Kononenko and Chub will remain on the station an additional six months, returning in Soyuz MS-25 with Dyson.

The Soyuz MS-25 launch took place a little more than an hour after a Dragon cargo spacecraft, flying the CRS-30 commercial cargo mission, docked with the station. That docking, with the zenith port of the Harmony module, took place at 7:19 a.m. Eastern, about 10 minutes ahead of schedule. The spacecraft launched March 21 on a Falcon 9 and is delivering more than 2,800 kilograms of supplies, experiments and hardware to the station.

CRS-30's Dragon will spend about a month attached to the ISS before coming back to Earth with a splashdown off the Florida coast.

Dragon is the only robotic ISS cargo craft capable of coming down in one piece (and hauling science gear from the station to researchers here on Earth). The other two operational freighters, Russia's Progress vehicle and Northrop Grumman's Cygnus, are designed to burn up in Earth's atmosphere when their orbital time is up.

Astronaut and UC Davis alum Tracy C. Dyson headed to the International Space Station for 3rd mission – KCRA Sacramento

Posted: at 4:42 pm

A NASA astronaut with Northern California ties is set to begin her third mission in space this week. Tracy C. Dyson, who earned a doctorate in chemistry at UC Davis in 1997, is one of three crew members who will blast off from Kazakhstan on Thursday to support Expedition 70 for a mission to the International Space Station. Her launch was set for Thursday morning but was delayed with less than 20 seconds left before takeoff. It is unclear when the launch will be rescheduled.Dyson will spend six months on the space station as an Expedition 70 and 71 flight engineer before returning to Earth in September. She told UC Davis for its Letters & Science magazine that her mission will include experiments and technology demonstrations. Among them will be a study on how fire spreads in space, though she is also ready to take on other tasks should the plan change. If theres anything Ive learned in the 25 years that Ive been doing this, its that the plan changes, she told the magazine. According to her NASA bio, Dyson previously spent more than 188 days in space, which involved more than 22 hours in three spacewalks. She was a mission specialist on the Space Shuttle Endeavor in 2007 and a flight engineer for Expedition 23/24 in 2010. Dyson grew up in Southern California and went on to compete in track and field while an undergrad at Cal State Fullerton, where she earned her undergraduate degree in chemistry. She became a pilot while attending grad school in Davis and also learned Russian and American Sign Language. NASA invited her to begin training as an astronaut about a year after she began post-doc studies at UC Irvine, according to Letters & Science magazine. The magazine reported that Dyson has also served as a consultant to The Martian movie and its star, Jessica Chastain. Dyson also has TV experience, serving as a host for NASAs StationLife series, and also as a guest judge on Cupcake Wars. NASA's launch coverage will air on NASA+, NASA Television, YouTube and NASAs website. | VIDEO BELOW | NASA seeks new astronauts. What to know
