ULA’s Vulcan recovery concept:
ULA CEO Outlines BE-4 Engine Reuse Economic Case
It amounts to severing the engines from the stage, post-separation, and bringing them down via IRVE-derived inflatable heatshields.
An interesting method, but AvWeek’s description makes it sound a bit crude compared to going all the way to a single P/A-module-like unit. It may […]
Bigelow’s already demonstrated that inflatables can be deployed and operated in space. Now they’re moving closer to demonstrating an inflatable habitat with actual people in it: On the BEAM: Headed for the Space Station.
In its packed configuration tucked aboard SpaceX’s Dragon resupply spacecraft, BEAM will measure approximately 8 feet in diameter.
Once BEAM is […]
Rose Eveleth: plumbing the important issues in science!
FWIW, I’ve worked in the space industry since 1997, around the time our favorite Twitter-based science expert and fashion critic was in junior high. Most of that work has been on projects involving vehicles for carrying people. I don’t recall a project or a period from then […]
This is the Drone Helicopter NASA Scientists Want to Send to Mars
Amusing. If lift is the limiting factor rather than volume or mass, that suggests to me that a bunch of these things could be sent on a single entry vehicle. Not unlike a certain NIAC proposal we put in last year, as it […]
In This Week’s Episode of #Science With @NeilTyson ….
Aliens, seeing Humans kill over land, politics, religion, & skin color, would surely ask, “What the f*%k is wrong with you?”

And my non-STEM friends wonder that I consider this guy an overhyped midwit and second-rate Carl Sagan […]
Sarah Hoyt tackles #Shirtstorm feminism (and a commenter attempting to deploy the standard Progressive argument tactics of snark, strawmanning, and faux-victimhood): No Space for Sewing Circles. John Hayward at Breitbart discusses the controversy as an example of thoughtcrime and compares it to #GamerGate: Comet Guy and the social-justice black hole Rose Eveleth and her […]
…To make up for Rose Eveleth, Chris Plante, and Arielle Duhaime-Ross tarnishing his big day with a petty and indecent snit over his shirt.
I chipped in $20.
ETA: Glenn Reynolds gives a short summary of the aforementioned petty and indecent snit, and makes this point:
It seems to me that if you care about […]
New Nanomaterial Takes the Stink Out of Submarine Air
Unlike amine, which is a liquid, the new material looks like sand. In fact, it is sand, except it is covered with tiny pores, each filled with molecules that selectively pull CO2 out of the airstream. Together, sand grain and molecule are called Self Assembled Monolayers […]
I like the simplicity of this, and the inventor mindset the exercise represents: NRL Invents CubeSat Release Mechanism To Deploy Solar Panels, Tethers
It’s a good motivation to me to do more monkeying around with ideas like this.
