43. Description. (Summarize the nature of the application and the services to be provided).
Astrobotic’s Peregrine Mission 1 will deliver government and commercial science payloads and
instruments to the surface of the Moon. Peregrine will be delivered to a trans lunar injection
orbit on a ULA Vulcan launch vehicle. Once separated from the Vulcan Centaur upper stage,
Peregrine’s trajectory will include one elliptical loop around the Earth before intersecting the
lunar orbit. After the initial highly elliptical lunar capture orbit, Peregrine will enter a lower
elliptical orbit where subsystem checkouts will occur. The last orbit is a 100 km circular orbit
in preparation for landing. The landing site on the Moon is in the Lacus Mortis basin and the
landing coordinates are 43.85 Deg. North and 25.17 Deg. East. Peregrine’s X−Band communication
system will be supported during all phases of the mission by NASA’s Deep Space Network DSN. DSN
will receive Telecommands from Astrobotic’s Mission Control Center and deliver them to Peregrine
along with ranging information using an X−Band uplink. DSN will receive Telemetry and ranging
signals from Peregrine’s X−Band transmitter. Peregrine’s mission will last a minimum of 17days and
a maximum of 78 days from launch date depending on the timing of the launch. After landing on the
Moon, Peregrine will begin its surface operations phase, providing the payloads with
power/communications services for attached payloads and communications services for deployed
payloads. Peregrine is designed to provide the services for one lunar day, after which time the
spacecraft will shut down and arrive at End of Mission EOM.

Looks like #VulcanRocket’s first flight Centaur V has finished up in final assembly and is making its way to the HPTC to verify all the helium plumbing.

Sorry, yes "Centaur V" that is awesome!! So much power and control. The best 2nd stage on the planet. The nozzle configuration looks strange?

Lacus Mortis was an early choice for Peregrine landing

A new landing site was chosen called Gruinhuisen Domes at edge Mare Imbrium.

Have they gone back to the earlier choice of Lacus Mortis?

I think it's spelled "Gruithuisen".

Astrobotic's web site still says Gruithuisen Domes and so NASA site says Gruithuisen Domes is Peregrine first mission target site.

I don't have precise target coordinates but Gruithuisen domes are located around 33 deg N 40 Deg W on Moon.

I'd describe them as on western edge of Mare Imbrium .

I'm guessing from Tory's comment about aiming for December launch that Peregrine may be planned for lunar landing just 1-3 days before Christmas Day to allow for maximum amount of solar  illumination time at landing site during its surface operations ?

Do we have something like an “aspirational” date for this launch?  SFN just has a placeholder for a date of Q4 2023.

OTOH, they don’t even have a placeholder for IFT-2 for Starship.

Going a bit off topic, AIUI SFN don't usually lists suborbital flights in their launch schedule.

The titles of launches in NSF are usually updated with the latest launch info: in this case, NET mid-December.

How long does it take from launch until Peregrine lands?

Edit: Looks like about a week?

Attached image of Peregrine trajectory that Astrobotic published some time back.

It shows the initial highly elliptical orbit around Earth.

It doesn't show any measurements though ! But, let's say diagram is " roughly" correct view of mission and that this highly elliptical orbit stretches almost to the edge of where Moons gravitational attraction is more than Earth's then I would suggest flight time ) if only one revolution in this highly elliptical orbit then outward flight to lunar orbit insertion might be around 8-10 days ?

But, without measurements hard to judge. But fairly certain longer than "typical" 3 days . And,if course, if they choose to do several revolutions in this orbit post launch shakedown/ checkout/ dwelling) will be much longer.

NASA CLPS site states following for Astrobotic Peregrine

"...Scheduled to land in 2023 at a mare unit recently named Sinus Viscositatis. The site is adjacent to the Gruithuisen Domes...".

The Astrobotic web site for Peregrine has had some updates and now says that the target site is the Gruithuisen Gamma Dome ( see attached cropped NASA image) .

So, please, Vulcan Centaur get the spacecraft on correct trajectory 🚀😄

KEY POINTS

United Launch Alliance plans to launch the inaugural flight of its Vulcan rocket on Christmas Eve, CEO Tory Bruno told CNBC on Tuesday.

ULA is currently working to build and qualify the upper stage of the rocket, running those tasks “in parallel,” Bruno said, with both expected to “get done in November.”

In the event ULA misses the December window due to shipping delays or bad weather, the company — a joint venture of Boeing and Lockheed Martin — will move back the launch to January.

Bruno said there are launch opportunities on Dec. 24, 25 and 26. If the launch does not take place on those days, there is a backup window in January, but Bruno did not state when in the month that would be.

A cynic would say ULA is not exactly prioritizing their employees, or those in the Space Force, by having them work on the 24th as well as the week leading up to it...  https://twitter.com/torybruno/status/1717124586762887447

That cynic would have never worked on a prototype project that was this far behind schedule, for whatever reason.

It's a Moon mission. The Moon is only in an optimal location for this mission once every 29-day lunar month. Your cynic would need to move the Moon around to allow for an earlier or later launch.
