An absolutely thrilling day for the team at Firefly! We will be delivering NASA payloads to the Moon using our Blue Ghost lunar lander!

I recall reading last year that Firefly was working with Israel Aerospace Industries to develop the failed Beresheet lunar lander into "Genesis," a new lunar lander concept. But now Firefly's website talks about their "Blue Ghost" lunar lander, and that seems to be what won this contract. Is Blue Ghost derived from/a new name for Genesis, or is this new in-house intellectual property that they aren't getting from IAI?

It's basically a new name for the same lander, which has been modified from the original Beresheet design.  The company put out a Payload Users Guide for Genesis last year and now has a new Payload Users Guide for Blue Ghost, with exactly the same illustration used in both for the lander's solar array options.  This presumably helps address some of the criticism of using a non-US design which hampered Orbit Beyond and caused them to abandon their first CLPS award.

I guess the next question is, can Blue Ghost get to the Moon on the Alpha, or does awarding a Blue Ghost contract implicitly also include the expectation that Beta will be flying by 2023? The PUG doesn't mention Alpha anywhere but does mention Beta once, saying "Our Beta launch vehicle (Fig. 4) will permit dedicated Trans-Lunar Injection (TLI) launch (250 km × 380,000 km) for Blue Ghost, as well as for other landers of similar size, increasing launch flexibility and PL mass to the lunar surface." So if it does require Beta, this is quite a vote of confidence from NASA, that Firefly will develop not just their lunar lander, but two separate orbital rockets in the next three years.

Beta is announced for early 2024 ...
Quote
The other $225 million would support growth initiatives, in particular a medium-class vehicle capable of placing 10 tons into orbit, about 10 times the capacity of Alpha. The company wants to make a first launch of that larger vehicle by early 2024.

... which translates to NET late 2025 in real time. So more realistically for 2023 is Alpha with kick stage.

My take on that is, Blue Ghost will fly with an existing launcher and the other LVs are only being discussed for future lunar missions.

So, the lander is named after Blue Ghost fireflies (Phausis Reticulata)? Or is there a Firefly fiction connection that I am not aware of?

The closest reference from the TV series would be the Blue Sun corporation, and maybe this is a nod to that too, but the firefly species you linked seems like the primary inspiration.

The Firefly announcement indicates they are using Alpha with a kickstage called SUV.

"With our Alpha launch vehicle providing launch services, and our Space Utility Vehicle (SUV) providing in-space mobility, Firefly is poised to ensure U.S. preeminence in the commercialization of cislunar space,” said Firefly founder and CEO Dr. Tom Markusic."

Yes. From the Firefly announcement.

"Blue Ghost (named after the rare Phausis reticulata firefly) will operate on-board payloads through lunar transit, during lunar orbit, and on the lunar surface for a complete lunar day (about 14 Earth days) and well into the freezing dark of lunar night. "

"With our Alpha launch vehicle providing launch services, and our Space Utility Vehicle (SUV) providing in-space mobility, Firefly is poised to ensure U.S. preeminence in the commercialization of cislunar space,” said Firefly founder and CEO Dr. Tom Markusic."

One read of that sentence could be "we will be offering Alpha, the Space Utility Vehicle, and Blue Ghost to serve all segments of cislunar exploration, but not necessarily using all three on missions together." E.g., they could launch Blue Ghost on a Falcon 9, and separately launch their Space Utility Vehicle on Alpha for other missions (including missions analogous to CAPSTONE), and the statement would still be true. I guess we'll have to see what they end up doing: if Alpha/Space Utility Vehicle has enough payload to carry Blue Ghost and its payloads to the Moon, I'll be impressed.

For reference, Firefly is saying that Blue Ghost can carry about 144 kg of payload (94 kg of CLPS payloads, another 50 kg of commercial payloads) to the lunar surface. That doesn't include the mass of Blue Ghost itself. In contrast, CAPSTONE is 25 kg total. Alpha is substantially larger than Electron (630 kg to 500 km SSO, compared to Electron's 200 kg), but even with the Space Utility Vehicle (which is analogous to Photon, although with more efficient ion thrusters), Blue Ghost seems like a pretty tall order to me.

Edit: I guess their PUG for Blue Ghost is a little more explicit about payload: they're actually only promising a max of 138 kg to the surface, or 135 kg if you also put 20 kg into LLO. So the 50 kg of commercial payloads they're including on the CLPS mission may implicitly include some payloads not actually going to the surface. Or one or more of the CLPS payloads themselves may be dropped off in LLO. So it slightly lowers the number from my previous paragraph. I don't think it affects the takeaway, though.

For reference, the SUV PUG says 500 kg to lunar orbit.
Quote
Figure 3 illustrates the degree to which the SUV extends the capabilities of the Alpha launch vehicle.
For missions exceeding 2000 km, the SUV delivers substantially more payload mass. Up to 600 kg can
be delivered to GEO and up to 500 kg can be delivered to lunar orbit.
https://firefly.com/wp-content/themes/firefly_aerospace/files/Firefly_Aerospace_SUV_PUG.pdf

so, just throwing a wag of 100 kg at the lander dry mass

delta v= 300*9.8*ln((500)/(100+94+50)) = 2109 m/s. This mission on Alpha seems plausible at least.

The SUV allows them to do rideshare missions, which they will need as Alpha is to big for dedicated launch of single smallsats to LEO or SSO. Even smaller Electron does very few dedicated launches of single smallsats, more often than not there are a few rideshare payloads. While both Photon and SUVs are kickstages/OTVs/satellite buses, their choice of fuel has pros and cons for both. SUV SEP is better for BLEO missions, for LEO missions high ISP means days if not weeks to deployment while less efficient Photon typically deploys within hour or two.

The SUV means Alpha can go head to head with F9 for rideshare missions, especially as they need an additional OTV to offer same capabilities as Alpha + SUV.

Alpha + SUV gives smallsat interplanetary mission planners another low cost option but with lot more capability than Electron+Photon.

Apparently they aren't using a firefly rocket for the CLPS task order. Alpha would need SUV which might not be ready (or be too slow), and Beta isn't slated to fly until 2024.

The lander will launch on a vehicle other than Firefly’s own Alpha rocket and Space Utility Vehicle (SUV) upper stage under development. The company said it has not yet selected a launch vehicle for the mission.

What could they use? F9, Pegasus etc is too expensive, Astra, Electron too weak. F9 GTO rideshare?
Which booster has the most soot? SpaceX booster launch history! (discussion)

According the Blue Ghost PUG, they need TLI for this ~140 kg lunar payload. GTO not enough. But SpaceX will probably launch several lunar landers per year from 2022, there should be rideshare opportunities.

Another option is the Ariane 64 TLI rideshare, planned for NET 2023.

Firefly is utilizing hardware from the Netherlands-based @isis_space  to deploy customer payloads on Alpha’s upcoming maiden flight. Multiple CubeSats by US institutions were integrated at our Vandenberg facilities with support from @isis_space  launch subsidiary, ISILAUNCH.

Firefly and ISILAUNCH are also working on joint manifest coordination for several rideshare and dedicated cluster missions starting in 2022, while ISILAUNCH will support payload integration on other Firefly missions as well.
