Every single used Apollo capsule is on display except the one from Apollo 1 (which is in bits in a warehouse somewhere in Marshall). Same for remaining spare LMs and S-V stages.

I'm not sure if there really is a major need for Angara A1-it's almost identical to Soyuz 2.1v (same upper stage, soon to use variant of the same first stage engine), but requires new pads.

That'd require three falcon heavy pads though. That wouldn't be at all cheap.

A liquid nitrogen ocean would also include other 'ices' that are liquid at that sort of range-methane, CO, et.c.

Have you seen any Apple-sponsored moon landings lately?

I'm pretty sure this isn't an official account.

Let's hope it's considerably more reliable than good 'ol Proton.

Capability is about the same as Proton. The application is covering the same payload ranges while launching from Russian sites such as Vostochny and Plesetsk-allowing Russia to wind down Baikonur and stop paying the Khazaks for the right to drop empty stages on them-and without using hypergolic propellants, which require expensive cleanup operations at stage impact sites.

Protip; somebody in a different enough timezone will also be in a different date.

Time zones are a thing.

There may be some coverage via Russian news programs, best bet is probably Rossiya-24.

While I agree QR codes probably ought to see a lot less use than they do, this doesn't make an awful lot of sense. Any smartphone that doesn't have easy access to an app store that'll have dozens of QR reader apps isn't worthy of the name.

Precambrian fossils of complex life are rare. Stromatolites and microbial mats are common.

Out of 86 launch attempts this year year so far, 40 were by launchers mainly using kerolox; that's more than a few. Incidentally you recall incorrectly, all flown SpaceX rockets have been entirely kerolox.

Yes. tenchars

Hasn't it been about a week since the last steam sale?

I wouldn't call it an 'idea', insomuch as there test flights where that actually happened.

In the past few years I can't think of a single orbital launch that was actually cancelled. You need to pay more attention to news about scrubs and aborts.

Too many to remember. To reduce it to notable ones; GRAIL Gaofen-1 Chang'e 3 Hayabusa 2 Orion EFT-1 Shenzhou 10 Tiangong 1 Antares maiden launch Naro-1 orbital launch Proton launch on 2/7/13 (the one that blew up)

The first liquid stage uses exactly the same Vikas engines as existing GSLV and PSLV models. ISRO have plans for a kerolox first stage in the future ULV, but none for cryogenic booster stages.

First (second?) stage is hypergolic. The second (third?) stage would be cryogenic, but for this flight it's a dummy.

No, look closer-the engine's nowhere near it. GSLV I and II had the same feature, although less obviously (black on black). Presumably it's a weightsaving measure

Likely never detected if not close to earth, and probably not found to be a spacecraft. For a body orbiting within the solar system I'd say definitely not, but a macroscopic object from outside the solar system would be a first and attract considerable scientific interest.

He's talking about price, not cost.
