Any news?  Clear skies ☀️ or cloudy ☁️?

Phil, what's your source for saying this?

Update: NASA to Join Astrobotic’s Media Call on Peregrine Mission One

Roxana Bardan
JAN 12, 2024
MEDIA ADVISORY
M24-010
NASA Headquarters
Johnson Space Center

Editor’s note: NASA updated this media advisory Jan. 18, 2024, to reflect a change in the date and time of the call, as well as the participants.

NASA will join an Astrobotic media teleconference at 1 p.m. EST, Friday, Jan. 19, to discuss updates on their Peregrine Mission One, which is carrying science for the agency as part of its Commercial Lunar Payload Services (CLPS) initiative.

The audio-only teleconference will stream live on the agency’s website.

Following a successful launch on Jan. 8, Astrobotic’s Peregrine lander experienced a propulsion issue after the spacecraft entered its operational state. This is preventing Astrobotic from achieving a soft landing on the Moon. Aboard the Peregrine spacecraft are five NASA science instruments, several of which are receiving power and gathering data.

Participants on the call include:

Joel Kearns, deputy associate administrator for Exploration, Science Mission Directorate at NASA Headquarters in Washington
John Thornton, CEO, Astrobotic, Pittsburgh
Dan Hendrickson, vice president, Business Development, Astrobotic
Sharad Bhaskaran, mission director, Peregrine Mission One, Astrobotic
Ander Solorzano, flight director and principal systems engineer, Astrobotic

To participate in the teleconference, media must RSVP online no later than two hours before the start of the call to Astrobotic.

A purported  YouTube live view of entry.
But it's been running for a good while now and I'm growing " suspect" of it?

As predicted by the APM1 team, Perigrine had  loss of signal at 20:59 over Canberra's DSS36. It was a shame it had to end this way, but the mission did it in style. This is the doppler profile from its final approach. It was a graceful dive.

Congratulations to Astrobiotics for being open with information and making many announcements about your current activities. You are one of the top companies in my book. Your team has certainly gained valuable experience in handling critical situations. I wish you much success and look forward to your next mission.

Quote from: Astrobotic - Update #21 for Peregrine Mission One - 1/18/24
Peregrine has been operating in space for 10 days and 8 hours and is approximately 30,000 miles above Earth, continuing its controlled re-entry. The trajectory remains on track with our planned path toward a safe area over open water in the South Pacific. The vehicle is stable, operational, and responsive. We remain in contact with appropriate government authorities to keep them informed of the vehicle's position and planned trajectory, which remains unchanged.

The stunning image here of Earth from Peregrine was taken by the mission team this morning. The first attempt to take this photo yielded an oversaturated image, with the Sun making the image too bright to see the Earth. As a result, the team precisely slewed the spacecraft to reposition the Sun to be hidden behind the thin payload deck strut just to the left of Earth, which produced the starburst effects on the vehicle and revealed the Earth's crescent. This image is completely unaltered.

We dedicate this image to our customers, partners, and team who all stood with us throughout Peregrine Mission One.

Thread meta commentary: Thread title needs to be corrected: Peregine Peregrine

[zubenelgenubi: D'oh! Spelling corrected. 🤦‍♂️]

Astrobotic finally posted the above update on their website, but as #22 instead of #21. #21 is correct.

Believed cause of failure was a valve faiked/got stuck/wad left improperly seated, which left open the connection between the helium high-pressure tanks to prime the MPS, and the lower-pressure oxidizer tank. Helium rushed in until excessive pressure accumulated, rupturing the tank and venting oxidizer overboard.

As pressure in the oxidizer tank decayed, it also allowed the failure area to be under less stress (I gather it was a small rupture, not the tank wall ripping open, and subject to some restorative structural force) and diminishing the leak rate. This was apparent from the status updates indicating ever-increasing lifetimes.

Nicely of them (or just because they were nerding out like the rest of us) they delayed their press conference a bit to wait on SLIM's.

It's a good time in our lives to have simultaneous discussions on two lunar lander missions, even if neither quite worked as fully hoped.

I had this similar feeling last July with Chandrayaan-3 and Luna 25. It's refreshing. And we got more coming.

(1/3) Final Update for Peregrine Mission One

Quote
This afternoon, Astrobotic received independent confirmation of Peregrine's safe, controlled re-entry yesterday over the South Pacific.

Peregrine Mission One has concluded. We look to the future and our next mission to the Moon, Griffin Mission One. All of the hard-earned experience from the past 10 days in space along with the preceding years of designing, building, and testing Peregrine will directly inform Griffin and our future missions.

(2/3) Peregrine and its payload teams have made a meaningful contribution to our lunar future, and we thank everyone who supported this mission. Courtesy of @ulalaunch, this video was captured from their #Vulcan rocket's payload fairing.

Peregrine has flown so Griffin may land.
