NASA's First Lunar Outpost at lunar morning. The pressurized element is derived from Space Station Freedom's laboratory/habitat modules. In the distance, a set of deployable experiment packages have been set up for astronomical and geological observations

Blue's new deployable heat shield seems very useful for something like this

Space Transfer Concepts and Analyses for Exploration Missions (STCAEM): A Boeing Mars mission concept from the 1990s. Two broad variants were proposed, with either chemical propulsion and aerocapture or nuclear-thermal propulsion

The "Mission-B" Cygnus, for use on the remaining CRS2 Cygnus flights. Mostly differentiated visually by a 4th PCM segment, but there are lots of subsystem changes as well to support longer-duration flights, reduce cost, and support more complex applications beyond simple cargo

Sadly, Dyna-Soar and MOL could have never met in orbit: X-20 was canceled the same day the MOL program began. I still think of them as siblings though

For an early crewed lunar flyby, a follow-on to Gemini-Agena was proposed where a modified Gemini would dock to a pair of Transtages, which would boost it to TLI

An operational derivative of the X-20 docked to a wet workshop built around an S-IV stage
Not much published on the station, but likely served a similar role to MOL

By request, Orion docked directly to Blue Moon. This would be a possible scenario either if Gateway is canceled, or in event of a failure on the lander requiring Orion to retrieve the crew
Any other missions/vehicles people want to see?

Size comparison of the FLO piloted lander vs Altair, Blue Moon, and (outdated model) Starship HLS. Its not outrageously huge overall, but it is a much taller ladder than I'd want to climb down

Following separation from the J-2S-powered second stage, Comet's nuclear-thermal third stage jettisons its aerodynamic insulation panels (similar to early Centaurs prior to Atlas II) and begins a coast phase prior to translunar injection

"The former USSR has a cheap booster for heavy-lift rockets"
"We'll take your whole stock"
One of the launch vehicle options for First Lunar Outpost was the Saturn V-derived base option but with up to 8 Energia strapon boosters

The First Lunar Outpost HLLV second stage compared to SLS's core stage. 2/3 as much propellant mass (its shorter, but wider and has a common bulkhead)

Beginning on the launch vehicle for First Lunar Outpost, starting with the NTR version of the Earth departure stage
There's a *lot* of variants of the FLO HLV, with NLS/ALS/Shuttle/Saturn/Energia-derived options. Any in particular you want to see?

Busy with commissions this week, so reposting the fat Apollo just to remind people of its existence
This is from a 1966 study on a crewed flyby of Eros using Apollo, Saturn, and MORL hardware. Possibly the worst human spaceflight proposal in history

Having had its layer of foam insulation stripped, and certain structures and systems scavenged in LEO for other purposes, what's left of a Shuttle External Tank is boosted to GEO by a TRW laser-thermal orbital transfer vehicle, to be melted down into material for a solar platform

The Titan Liquid Boost Module continues to fire for a minute and a half after SRB separation. After burning to depletion, it will separate from the External Tank and be disposed of into the Pacific

Saturn-Shuttle
I used the as-flown Orbiter, and a tank similar to what was flown, instead of the actual concepts from when Saturn-Shuttle was proposed, I figure the design of those parts would've trended in that direction anyway
