Update 08.01.24:
Launch has been a big success for ULA and Blue Origin. Unfortunately Astrobotic has been informing the public about issues with regards to positioning solar panels. The propulsion system seems to be losing fuel.

Peregrine Mission One
Peregrine Lunar Lander by Astrobotic Technology will ride on the maiden flight of the Vulcan rocket by United Launch Alliance (ULA).
The lander has a payload capacity of 90 kg. Among the payloads is a 33 kg Rover from the Carneige Mellon University and 5 extremely small (12 cm, 60 g) rovers from the Agencia Espacial Mexicana]( https://en.wikipedia.org/wiki/Agencia_Espacial_Mexicana).

The lander does not have heaters onboard. Which means it will probably not survive the lunar night (14 days). The mission on the surface is expected to last around 10 days.
There are at least two more Peregrine missions to the Moon planned. Each with successively higher payload capacity.

Griffin Mission One
Later in 2024, the bigger brother Griffin is expected to launch on a Falcon Heavy for the south polar region of the Moon.
First First: Vulcan Maiden Launch
Being part of a maiden launch is usually considered high risk in the space industry. The first launches have the highest risk of failure and payloads are usually very expensive and take a long time to be replaced. Industry standard is around 90 to 95% success rate, with failures heavily slanted towards the first launches.
If an important mission like this rides on a maiden flight, ULA is a great address because they have an outstanding launch track record:
- Atlas V achieved 98,94% reliability (93 out of 94).
- Delta IV achieved 97,73% reliability (43 out of 44).

Vulcan Rocket
Vulcan can launch in four configurations, depending on how many solid rocket boosters (SRB) it has attached at launch (0, 2, 4 and 6).
This launch will launch in the VC2 configuration (2 SRB). That configuration is comparable to SpaceX’ Falcon 9. In the VC6 configuration, the Falcon Heavy has about double or triple payload mass to various orbits.
| Rocket | Mass to LEO [kg] | Mass to GTO [kg] |
|---|---|---|
| VC2 | 19,000 | 2,600 |
| Falcon 9 | 22,800 | 8,300 |
| VC6 | 27,200 | 14,500 |
| Falcon Heavy | 63,800 | 26,700 |
Second First: BE-4 Engines
It will be the first time that Blue Origin’s BE-4 engine will take to space. It is fueled by liquid oxygen and liquid methane, like SpaceX’ new Raptor engine, which is used on Starship.
Scott Manley explaining why methane/oxygen engines are the new hype in space flight:
Why Next Generation Rockets are Using Methane
ULA is for Sale
Potential bidders:
- Blue Origin (Jeff Bezos)
- Cerberus (private equity)
- Textron (Cessna)
A successful launch of Vulcan could make that a deal happen in a short period of time. As Cerberus is a private equity company, it is possible that they could team up with either of the other two bidders.
Jeff Bezos doesn’t need a partner to afford ULA. Why should he share ownership? He would inherit a great track record and could access national security missions immediately.
Cerberus might be building their own integrated space conglomerate. They could easily partner up with Textron and build together for a later spin-off.
