Episode 1609: Double Stars Rising

Talking Space

After years of development, testing, disappointment, and perseverance, NASA astronauts Butch Wilmore and Suni Willams took Boeing's CST 100 Starliner to the International Space Station for its first flight with a human crew. The team discusses all facets of the launch, rendezvous, docking (not without its moments of drama), and public reaction to the mission thus far.

Also this week, the fourth test flight of the SpaceX Starship Super-Heavy booster and a re-entry test of the Starship vehicle itself. The super-heavy vehicle is critical for NASA's Artemis lunar landing program, and a derivative of Starship was selected by NASA to be the human lunar lander used on Artemis III. The team puts the fourth Starship test into perspective.

Starship development was also critical for the SpaceX/ Yusaku Maezawa dearMoon program, which was to take Maezawa and eight invitees into orbit around the Moon. However, Maezawa announced that since a 2023 launch had become "unfeasible" and lacked a "clear schedule," he was canceling the program. The announcement drew some ire in the space community, and we examine the fallout.

One of The Hubble Space Telescope's three gyroscopes used to point the telescope to distant objects has failed. We look at a Media Telecon where NASA's astrophysics leader, Dr. Mark Clampen, indicated the agency will continue to utilize Hubble in a "one gyro mode" so the iconic telescope can still deliver good science with only a 20% loss of capability. The orbiting telescope is in overall good health and should continue to operate until 2035. At the same teleconference, Dr. Clampen announced that NASA has no intention of launching a Hubble servicing or re-boost mission in the foreseeable future. This news ends the SpaceX/Polaris plan to launch a possible servicing mission to the telescope. A May 2024 NPR article by Nell GreenfeldBoyce also reported NASA's concerns about the unsolicited proposal.

Sadly, the past few episodes have ended in obituaries, and that trend continues. The team takes a few moments to remember NASA Apollo 8 Astronaut William Anders, who died in a plane crash this past weekend.

All this and more in this edition of Talking Space!

UPDATE ONE: During the show, we reported that the new undock date for Starliner was on 22 June. After we published, NASA and Boeing decided to do some more analysis on the thruster issues experienced during last week's docking to the ISS. To understand the Starliner Service Module more, ( the service module does not return ) NASA and Boeing have now indicated that Starliner will undock from the ISS at 10:10 PM EDT on Tuesday, June 25th with a landing planned at the White Sands Space Harbor in New Mexico at 4:51 AM EDT on June 26th.

UPDATE TWO: In A Blog Post Today (21 June 2024) NASA and Boeing Space announced that they are waiving the return date of 26 June for Starliner, with a new date to be announced at a later time. To quote the NASA blog post: " The move off Wednesday, June 26, deconflicts Starliner’s undocking and landing from a series of planned International Space Station spacewalks while allowing mission teams time to review propulsion system data."

Steve Stitich, NASA's Commercial Crew Program manager said “We are strategically using the extra time to clear a path for some critical station activities while completing readiness for Butch and Suni’s return on Starliner and gaining valuable insight into the system upgrades we will want to make for post-certification missions.”

NASA Reports that Starliner remains healthy and that CFT Crew Members Butch Wilmore and Suni Williams continue to support the Expedition 71 Crew with their activities on the International Space Station.

Talking Space will continue to follow the story as it develops.
