Episode T+123: The Noosphere of Influence

Main Engine Cut Off

NASA made a series of announcements about their ISS commercialization effort and the first Commercial Lunar Payload Services missions, and Firefly unveiled their Orbital Transfer Vehicle. And there’s a really interesting connection between all three stories.

Episode T+122: National Security SpaceX Lawsuit

Main Engine Cut Off

NSSL, LSA, OMG! Last week, SpaceX filed a lawsuit against the US Air Force over the Launch Service Agreement development contracts. We’re mere months away from bids being due for the National Security Space Launch Phase 2 launch contracts, so I figured now would be a good time to take a step back to explain what these programs are, why they matter, and why SpaceX is filing this lawsuit at this moment in time.

Episode T+119: Dr. John Charles

Main Engine Cut Off

Dr. John Charles spent nearly 33 years at NASA—most recently as Chief Scientist of the Human Research Program—working on human spaceflight through Shuttle, Mir, ISS, and beyond. He lead missions such as STS-95 (John Glenn’s Shuttle flight), STS-107, and the Twins Study with Scott and Mark Kelly. He retired from NASA in February 2018 and is now the Scientist in Resident at Space Center Houston. We talk about his career, the human spaceflight issues he worked and solved in his time at NASA, and the things that need to be solved for the exploration of the Moon, Mars, and beyond.
