Payload info

Psyche

Psyche is an orbiter mission that will explore the origin of planetary cores by studying the metallic asteroid 16 Psyche. Lindy Elkins-Tanton of Arizona State University is the Principal Investigator who proposed this mission for NASA's Discovery Program. NASA's Jet Propulsion Laboratory (JPL) will manage the project.

16 Psyche is the heaviest known M-type asteroid and is thought to be the exposed iron core of a protoplanet, the remnant of a violent collision with another object that stripped off its outer crust. Radar observations of the asteroid from Earth indicate an iron–nickel composition. On 4 January 2017, the Psyche mission was selected for NASA's Discovery #14 mission

I wish SpaceX would stream it on YouTube instead of X. For some reason those live streams never load for me.

That's not really a surprise though, right?

Thankfully, Nasa and TheLaunchpad stream it live on youtube.

Me too buddy, me too. Luckily, there will be no shortage of coverage for a high-profile mission like this. I've added a bunch of YouTube livestream links in the main post. You can pick and choose your favourite commentators.

Are you logged in? It might be further efforts by Xitter to silo content away from non-users. I'll try to post a direct link to the tweet (which is usually viewable without logging in) if I get the chance.

Yep, although I only tried through the Android app.

SECO-2 M-vac shutdown and nominal orbit insertion! Awaiting payload deployment.

[–] [email protected] 3 points 1 year ago

T-3 minutes. Everything looking good so far.

[–] amansman 3 points 1 year ago

Fueling has started. 85% chance.

In the booster IDs such as 1065-4, does the "-4" indicate that this is the fourth launch for booster 1065?

[–] [email protected] 5 points 1 year ago* (last edited 1 year ago) (1 children)

Yes, both 1064 and 1065 previously supported the USSF-44, USSF-67, and Jupiter-3 missions. Psyche will be the fourth launch for these FH side boosters, and they will likely be reused for USSF-52 and Europa Clipper.

[–] clothes 3 points 1 year ago

Wow thanks! It's awesome that reusability let's boosters have stories like this, especially in cute pairs.

[–] [email protected] 3 points 1 year ago

Weather is 40% go. Current launch time is 2023-10-13 14:19 UTC. Backup launch time is 2023-10-14 14:24 UTC.

Side booster landings confirmed!

[–] [email protected] 3 points 1 year ago

Booster engines cutoff and booster separation!

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago)

SECO-1 and nominal coast orbit! The second stage will coast for ~45 minutes before igniting the M-vac again for final injection and deployment.

[–] [email protected] 3 points 1 year ago

T-1 minute. Falcon Heavy is in startup. LD go for launch.

[–] [email protected] 3 points 1 year ago

SES-2 M-vac ignition! Burn will last ~2 minutes.

Confirmation of carrier signal!

Edit: Webcast ended. Now we wait 6 years... see you all in 2029!

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago)

Psyche separation confirmed! Awaiting acquisition of the carrier signal for direct communication with the Psyche spacecraft.
