In recognition of the successful LOFTID test today I give you once again ROOST, which might be the largest inflatable heatshield vehicle ever proposed.

Mariner IV was a crucial mission to Mars. In July 1965 it gave us our first real data on the atmosphere, forcing advance planners to look at new Mars lander concepts. #space #history #spacehistory #Mars

Designing a Shuttle heat shield nearly defeated engineers. For a time, going back to one that charred and burned away was considered.

Another one in honor of DART — a plan to steer a chunk of asteroid toward an impact on Earth. I don't believe the author thought through all the implications. #DARTMission

Still trying to work out why they didn't invoke aerogel as a capture medium. Was the expected particle impact velocity too great? #space #history #spacehistory #comets #ESA

A clever plan for launching big fat cargoes into LEO — and possibly putting the Shuttle ET to work in orbit, too. #space #history #spacehistory
