The fourth USSF GPS-III (GPS III-IV) satellite on top of the Falcon 9 Block 5 launch vehicle operating at SpaceX in the early morning of October 3, 2020.
Just a few weeks later, in early to mid-November, Rubins and her team will welcome a crew of four, called Crew-1, SpaceX's first operational Crew Dragon mission.
A new crew of three astronauts will leave for the International Space Station tonight and launch a Russian Soyuz rocket from Kazakhstan.
In partnership with SpaceX, NASA has reduced the reliability of Russian Soyuz spacecraft, which have recently become more expensive. A seat on the SpaceX capsule is expected to cost $ 55 million, including funding from NASA to build its new Crew Dragon spacecraft. The companies had initially been required to prove to NASA that their spacecraft would meet the agency's requirements for human space flight by 2017.
Now those keeping score will note that NASA had originally planned to launch this mission in September.
However, this is not the first time SpaceX is facing an issue with its launches.
The spacecraft, operated by US company Space Exploration Technologies (SpaceX) Corp., was initially scheduled to blast off from Earth bound for the International Space Station on October 31.
SpaceX launched its first crewed mission to the area station in Could, marking the primary time a non-public firm had despatched people into orbit.
"NASA and SpaceX will use the data from the company's hardware testing and reviews to ensure these critical missions are carried out with the highest level of safety", the agency said in the statement.
The gas generator utilises small amounts of fuel and oxidiser which it burns separately from the main combustion chamber to power the turbine.
As a result, Crew-1 has slipped from placeholder launch dates on October 23rd and October 31st to sometime in "early-to-mid November", while most external sources suggest that a mid-to-late November target is more likely.
Elon Musk, SpaceX's founder and CEO, tweeted after the abort of this mission, that the countdown was stopped after an "unexpected pressure rise in the turbomachinery gas generator".
Meanwhile, SpaceX says it shipped the first Crew Dragon-derived Cargo Dragon to Florida several days ago, meaning that the company will soon begin simultaneous preflight processing of two upgraded Dragons for the first time.
Launch of the six-month mission, SpaceX Crew-1, is to be the first regular trip to the International Space Station as part of NASA's Commercial Crew Program, which allows NASA to contract for launch services from private companies.
