A Russian Soyuz rocket carrying three astronauts sure for the Worldwide Area Station skilled a uncommon abort on the launch pad on Thursday (March 21) whereas the crew waited expectantly inside their spacecraft.
The abort occurred simply 21 seconds earlier than the Soyuz rocket was to launch NASA astronaut Tracey Caldwell Dyson, Russian cosmonaut Oleg Novitskiy and spaceflight participant Marina Vasilevskaya of Belarus to the Worldwide Area Station (ISS) from Baikonur Cosmodrome in Kazakhstan. Liftoff was scheduled for 9:21 a.m. EDT (1321 GMT).
“The Soyuz launch to the area station has been aborted,” NASA spokesperson Rob Navias stated throughout reside commentary. “So, no guests to the International Space Station at the moment. The following alternative to launch, pending decision of what occurred at the moment, could be Saturday morning,” he added.
“No purpose has but been given for the abort,” Navias stated.

Navias stated the abort was triggered by an automated system shortly earlier than engine ignition; two umbilical connections have been retracted away from the rocket forward of the deliberate launch. Roscosmos, Russia’s area company, despatched engineers to the launch pad shortly after the abort to ensure the automobile was protected and crew might be extracted.
“The automobile is protected, all fueling operations have ceased,” Navias stated. “All security instructions have been offered onboard the rocket so there is no hazard to the crew. They’re completely protected.”
NASA’s Mission Management heart radioed information of the launch abort to astronauts aboard the ISS shortly after it occurred. Flight controllers made it clear the Soyuz crew was protected.
“Station copies; aborted,” station commander Andreas Mogensen of the European Space Agency replied. “Most significantly, Station copies crew are protected.”
Russia’s Soyuz rockets and crewed Soyuz spacecraft are workhorse transport autos that commonly fly cosmonauts and astronauts to and from the ISS. Roscosmos has used the spacecraft for crewed flights all through the 24-year historical past of the ISS, in addition to throughout its earlier Mir space station program.
An abort simply earlier than launch is exceedingly uncommon for Soyuz rockets. In October 2018, a Soyuz rocket carrying NASA astronaut Nick Hague and cosmonaut Alexey Ovchinin suffered an in-flight abort that pressured the crew’s Soyuz capsule to tear free from its rocket and make a harrowing emergency touchdown. That abort was traced to a deformed sensor on the Soyuz rocket.
Dyson, Novitskiy and Vasilevskaya are set to launch on a mission to affix the continuing crew on the Worldwide Area Station. Dyson and Novitskiy plan to spend six months aboard the area station as a part of its Expedition 71 crew, whereas Vasilevskaya is ready to embark on a 12-day keep and return house with the outgoing Expedition 70 crew.
Precisely when the three area vacationers will launch, nonetheless, is unclear. Whereas Roscosmos has stated the subsequent window to launch the trio will open on Saturday, engineers with Soyuz rocket maker Energia must perceive why at the moment’s Soyuz launch aborted and carry out any fixes that could be required. NASA has pledged to share updates as they’re acquired from Roscosmos and Energia.
In the meantime, in Florida, one other rocket is counting all the way down to launch to the ISS at the moment.
An uncrewed SpaceX Falcon 9 rocket and Dragon cargo ship are scheduled to launch greater than 2 tons of contemporary provides to the ISS from Area Launch Advanced 40 on the Cape Canaveral Space Force Station in Florida. Liftoff for that mission is scheduled for 4:55 p.m. EDT (2055 GMT) and may proceed as deliberate, Navias stated.
“The preliminary phrase is that the Falcon 9 launch of the CRS-30 resupply mission to the station will seemingly proceed as deliberate at the moment,” he added.
NASA and SpaceX will present a livestream of the CRS-30 cargo launch, starting at 4:35 p.m. EDT (2035 GMT).
