Would take the wind out of the sails of calls for “traditional” hypergolic landers for HLS, too. There aren’t any real large hypergol engines in production right now that would be suitable for a lunar lander. There are several methane/LOx, kerolox, hydrolox engines that are.
There is the ISRO Vikas gas generator engine running on UDMH and N2O2 that is used in all their launchers. Of course with a thrust of 800 kN, maybe too much power. Only consider it after ISRO developed a throttleable version that gimbaled.

Yeah, I meant domestic hypergol engines. India could use hypergols

[...] 845kg CH4 should correspond to about 3000kg LOX at 1:3.6.

It's difficult to be precise without knowing the CH4:O2 mixture ratio used by the Nova-C VR900 main engine. For the stoichiometric mole ratio of 1:2 (sure that's not what they're doing but it's a start) 422 kg of O2 would oxidize 106 kg of CH4, right? Is 845 - 106 = 739 kg anywhere close to what might boil off in flight?

DOGE-1 (12U, 13.8kg, Geometric Energy) (deployed from F9 second stage)

I didn't find any proof DOGE-1 will actually launch as a surfboard payload other than they received the FCC licences a month ago.

Looks like it's postponed. Any idea what their next opportunity is?

Where are you seeing that it's postponed?

MOSCOW, January 24. /TASS/. The start of the Crew-8 mission, which includes Russian cosmonaut Alexander Grebenkin, is scheduled for February 18, follows from the report of the head of the department of the Rocket and Space Corporation (RSC) Energia, Rafail Murtazin, as part of the XLVIII Academic Readings on Cosmonautics in Memory of S.P. Korolev ("Royal Readings").
“[Start of mission] Crew-8 - 18.2 (February 18 - TASS note),” says Murtazin’s presentation slide. The crew will go into orbit on the American ship Crew Dragon.

NET February 29th or March 1st if IM-1 launches on time. If IM-1 launch slips then Crew-8 is NET February 22nd:

Quote
Thanks to @cbs_spacenews for his question on today's Crew-8 presser we now have some more clarity!

Answer is basically: If IM-1 launches on time then Crew-8 would launch around the 29th or 1st but if it slips, then Crew-8 could be launched earlier around the 22nd.

SpaceX performed another test of this system overnight with even more venting visible and for a much longer duration (130x timelapse below).

A wet dress rehearsal of this system with the IM-1 lander is on tap for the middle of next week.
