They filed for an FCC license but didn't include much of the paperwork yet.  They're asking to use the simplified small satellite licensing but they need a waiver of the mass limit.

"The wet mass of the BLUE GHOST will be 1517 kg. This wet mass includes 1036 kg of propellant. And the dry mass is 478.5 kg."

I wish them the best, but with all the landing problems by many others trying to land on the moon I give this one maybe 25% chance of successfully landing.
Starship, Vulcan and Ariane 6 have all reached orbit.  New Glenn, well we are waiting!

Lesson from SLIM: don't design an engine with a nozzle that gets blown off.
Lesson from IM-1: rigorously review your pre-launch procedures and rigorously implement them using a two-man rule.

Those were both good landers that almost worked.  But you may be correct: Firefly might find a different way to mess up, and you cannot really depend on yet another near-miraculous recovery from a catastrophic failure to salvage at least some of the mission.

BGM1 is currently expected to launch Q4 2024 (Nov 16th, 2024) on a SpaceX Falcon-9 rocket and land on the moon roughly 6 weeks later.

Falcon 9 launches it to roughly 190 x 316,000 km, 35 deg.
Mass: 478 kg dry, 1517 wet

The Blue Ghost Lander uses a storable bipropellant main propulsion system with a main engine, 8 bipropellant RCS thrusters, and 4 x 3-axis augmenting cold gas ACS thrusters. The Leros-4 bipropellant main engine is manufactured by Nammo (U.K.) Ltd. Both the main engine and Firefly RCS thrusters use a propellant mixture of monomethylhydrazine (MMH) fuel and a nitrogen tetroxide variant (MON-3) oxidizer. The ACS cold-gas thrusters use Helium which also serves as the bipropellant pressurant gas.

The 3.5 Earth-centered orbits are designed for a lunar gravity assist to raise the Landerís perigee, reduce the cost of correcting for launch vehicle injection error, provide ample time for troubleshooting and checkout, and perform contractually mandated science operations. The trajectory design also includes consideration for avoiding eclipsing, so the vehicle can remain power positive, as well as to minimize communication blackouts by ensuring line-of-sight to ground stations. The period of these orbits is between 7 and 9 days for a total time in Earth orbit from launch to LOI of 24 to 31 days. Due to constraints on the Landerís lunar orbit, there is only one capture opportunity per 27-day Moon orbit. Therefore, each monthly launch window lasts seven days but targets the same LOI date.

One step closer to launch and landing as our Firefly team installed Blue Ghostís main engine designed, built, and tested with @Nammo. Weíre on our final checklist before the lander starts its journey to the moon.

The next Blue Ghost payload, Stereo Camera for Lunar Plume-Surface Studies (SCALPSS), has been successfully integrated! SCALPSS will take photos during the landerís descent to capture the impact of rocket plumes on lunar regolith.

There was a recent FISO presentation on LuGRE (April 24, 2024)

Another payload successfully integrated on the Blue Ghost Mission 1 lander! Developed by @NASA, @NASAGoddard & @ASI_spazio, the Lunar GNSS (Global Navigation Satellite System) Receiver Experiment (LuGRE) will investigate whether signals from two GNSS constellations can provide precise navigation in transit and on the Moon. #BlueGhost #FireflyAerospace
