NASA Space Launch System launch: Artemis 1

[DocM]

Lunar test flight of the Space Launch System (SLS)  launcher, Orion spacecraft and its European Service Module (built by the European Space Agency).

 

Artimis 1: launch to a high rectilinear lunar orbit, test systems etc., return to Earth. Also dep!oy some cubesats -  which have a problem related to the numerous SLS delays (see bottom).

Artemis lunar missions will be an international effort involving the nations of the Artemis Accords. 

 

Lunar surface missions will use the SpaceX Starship HLS (Human Landing System) initially, with a second lander  built by another contractor  added later for redundancy. 

 

For most Artemis missions Orion will launch to the Lunar Gateway, a small space station in a high rectilinear  lunar orbit. For landings, the crew will transfer to a Human Lander System vehicle. 

 

For Gateway logistics, SpaceXs new robotic Dragon XL cargo vehicle will do the deliveries (launched by Falcon Heavy.)

Launching 8:33 am  EDT, 12:33 GMT less than 30mins.

Scrubbed. 

 

Earliest opportunity is September 2nd (depending on the troubleshoot of the #3 engine bleed issue which scrubbed today's attempt)

Scrub Launch System, amirite?

In all seriousness, this is to be expected for the first launch. Until they get one successful flight, they're going to progress with excessive caution.  It's hard to rely on simulation data for something like this and delays are far better than an explosion.

The wet rehearsals didn't go great, so it could be a while before we see them hammer the Launch button.

 

Maybe Starship will launch first after all. 😁

Artemis 1, attempt #2

 

Date: Saturday, Sept 3

Window: 1417 - 1617 Eastern

 

Backup: Monday, September 5

 

There is still a dodgy sensor, and if they need to roll the vehicle back for work it could delay the launch several weeks or months.

 

This is a really high risk lunch because of SLS's low production rate. A failure + redo would use the Artemis 2 hardware, which would delay a retest into late 2023 or 2024. Artemis 3 hardware then becomes the Artemis 2 crewed test, and so on.

 

Assuming no big setbacks, the uncrewed Starship HLS test landing at the Lunar south pole is planned for 2024/2025.
