S8 Ep1002: Bob Zimmerman discusses the crew selection for NASA's Artemis 3 mission, which has been simplified to focus on Earth-orbit docking tests. He also examines private sector developments, including German startup Isar's funding, Stoke Space's reusable rocket
NASA's Artemis 3 mission has been restructured into a simplified Earth-orbit rendezvous and docking test, focusing on validating critical systems rather than landing on the Moon. The three-person crew includes two veterans and a rookie who was backup for Artemis II, with a backup astronaut on standby. The mission will involve SpaceX's Starship (for docking tests), Blue Origin's Blue Moon lunar lander, and a new SLS launch vehicle—though the reliability of Blue Origin's New Glenn remains uncertain. Despite the complexity, the Earth-orbit scenario dramatically improves safety margins. Meanwhile, German startup ISAR raised $312 million, bringing its total funding to nearly $900 million, and is preparing a launch from Norway. Stoke Space, an American startup, is nearing its first launch of Nova, a fully reusable two-stage rocket with a revolutionary ring-nozzle upper stage that can return like a capsule. This would make it the first fully reusable rocket besides SpaceX's Starship. Catalyst, another startup, is repurposing its demo mission to rescue the aging Swift-Gerrells Space Telescope, with a launch expected by the end of June. In Canada, a Nova Scotia spaceport received a $200 million government lease to boost national prestige, though it currently only supports suborbital flights and lacks a real domestic rocket company. India and Japan are also advancing private space initiatives, with India opening its LVM-3 rocket to private operators and Japan’s $6.
Artemis 3 is now a simplified Earth-orbit mission focused on testing docking between Starship, Blue Moon, and Orion—no lunar landing planned.

Artemis 3 Crew and Mission Simplification
“The original purpose of this mission was let's go to the moon. Let's do all this sending people to land on the moon. And he said, that's absurd. So he's doing it in Earth orbit.”
Earth-Orbit Safety and Rendezvous Complexity
Despite the complexity of multiple rendezvous with untested vehicles, Earth orbit offers vastly higher safety margins. The mission will rely on autonomous systems with human backup, and the focus is on testing docking and heat shield systems.
ISAR’s Funding and Launch Progress
“They've raised an additional $312 million in investment capital, which brings the total amount of cash the company's got on hand to just under a billion, over 900 million dollars.”
Stoke Space’s Fully Reusable Nova Rocket
“This will be the first – this and Starship Super Heavy will be the first completely reusable ships.”
Catalyst’s Swift-Gerrells Rescue Mission
“This is an incredibly fast-moving operation for Catalyst, which has never done it before. This is a demo mission. If they succeed here, they will put themselves on top of the heap of the orbital servicing market and they will save a telescope.”
