Main Engine Cut Off

Jake Robins of the WeMartians Podcast joins me to discuss the state and future of the Mars exploration program, lean sample return, and more.

I spent 2 minutes and 40 seconds in the shadow of the Moon in Gallatin, TN. Totality was an incredibly powerful experience, and I wanted to share what it was like to be there as best I could.

Caleb Henry of SpaceNews joins me to discuss the slowdown in GEO satellite orders, the latest on the big LEO constellations, and what’s up with the sky falling.

Rocket Lab completed their investigation into what went wrong on their first launch, Virgin Orbit’s carrier 747 arrived in Long Beach, and I discuss a few NASA-backed advanced propulsion projects.

I spend some time thinking through what the future of the ISS holds, and what may come after it.

Eric Berger returns to the show to talk about Elon Musk and SpaceX’s crusade against cost-plus contracting, the end of Red Dragon, where NASA policy is heading, and what SpaceX may have in store for the Air Force’s next round of development contracts.

Loren Grush of The Verge joins me to talk about Falcon Heavy, SpaceX cancelling Dragon 2 propulsive landings, Red Dragon riding off into the sunset, Moon Express, US space policy, and a whole lot more.

XCOR laid off the rest of its staff and is closing up shop after losing a contract with ULA, which leaves ULA in an interesting spot for Vulcan-ACES. On the ULA side, they won their first Phase 1A contract from the Air Force, and the contract price sheds some light on just how much they’re cutting their costs.

SpaceX launched two missions last weekend, flew new titanium grid fins on Falcon 9, and are really picking up the pace. And Blue Origin got cozy with the Alabama Launch Alliance by announcing that they’ll build the BE-4 production facility in Huntsville—if the engine is chosen for Vulcan.

Boeing’s proposal won Phases 2 and 3 of DARPA’s XS-1 program, and I’m pretty bummed about it. And the Air Force announced that SpaceX will launch the fifth X-37B mission in August.

Dr. Thomas Lang, Professor of Radiology and Biomedical Imaging at the UCSF School of Medicine, joins the show to discuss human health and physiology in space.

Rand Simberg joins me to talk about his recent trip to the Space Tech Expo, the dawning of the age of in-space manufacturing, the future of SLS and Orion, the National Space Council, and a lot more.

Last week was rough for the Space Launch System. An issue with weld tooling was discovered, with some serious consequences, and then a LOX tank dome was dropped and damaged beyond repair. To top it off, NASA announced that EM-1 will fly without crew, and is delayed until 2019.

Eric Berger, Senior Space Editor at Ars Technica, joins me to talk SLS/Orion, New Space vs. Old Space, space policy in the Trump administration, and why the fight might not be settled until 2020.

As the award date approaches for the 2018 Air Force launch vehicle development contracts, we keep hearing from Congress about how they would like to see it go. And I discuss the future of Antares and the Next-Generation Launch Vehicle in light of the continuing flights of Cygnus on Atlas V.
