This Week in Space 150

On episode 150 of This Week in Space, it's our Listener Special edition! Not only do we answer your questions and respond to your comments, but we lined up a number of your most tummy-tickling space jokes in the humor shooting gallery. This one is more fun than wearing new shoes! Join us as we talk about asteroid 2024YR4, the Space Launch System's prospects, Katy Perry in space, the newest lunar missions, the X-37B "secret shuttle," Apollo-era flight director Gene Kranz and astronaut Buzz Aldrin, solar sails, the cage match between Elon and astronaut Andreas Morgenson, and the best meteor shower of the year!

Headlines

• Asteroid 2024 YR4 no longer a threat - The Earth-shattering asteroid that briefly had a record high 3.2% chance of impact has been downgraded to a 1 in 20,000 risk after pre-discovery data was analyzed, sparing Barstow and the rest of Earth.
• SLS faces uncertain future - Even long-time supporters like Scott Pace (former National Space Council secretary) are suggesting an "off-ramp" from the SLS rocket to commercial providers, signaling a potential shift in NASA's approach to lunar missions.
• Lunar Trailblazer mission communication issues - The recently launched lunar orbiter briefly lost contact after launch on a Falcon 9 but has since established a heartbeat.
• Blue Origin announces all-female crew for NS-31 - The upcoming mission will feature singer Katy Perry, Lauren Sanchez, and four other accomplished women, marking the first all-female crew since Valentina Tereshkova's solo flight in the 1960s.
• Blue Ghost lunar landing imminent - Firefly Aerospace's first moon lander is scheduled to touch down on March 2nd, joining two other private landers (from Intuitive Machines and ispace) headed to the moon in the coming weeks.

Listener Questions

• X-37B space plane purpose - The hosts discussed the secretive Space Force vehicle that's been in orbit for 908 days, likely testing technologies like hall thrusters and conducting reconnaissance.
• Elon Musk vs. astronauts controversy - The hosts addressed the Twitter/X confrontation between Elon Musk and astronauts (including Andreas Morgensen) regarding claims that astronauts were "stranded" on the ISS for political reasons.
• Gene Kranz's impact during Apollo - Rod shared his experience interviewing the legendary flight director, highlighting Kranz's "dictum" speech after the Apollo 1 fire and his transition to a more reflective persona later in life.
• Meeting Buzz Aldrin - The hosts described Aldrin as passionate, technically brilliant, and candid about his personal struggles, with Tariq sharing how Aldrin was the subject of his first professional space article in 1999.
• Solar sail technology potential - They discussed the success of Planetary Society's LightSail 2 and other solar sail missions, lamenting that the technology hasn't been utilized more extensively for deep space missions.
• Best meteor showers to observe - The hosts recommended the Perseids (August), Geminids (December), and Leonids (November) as the most impressive annual meteor showers, emphasizing the importance of dark skies for optimal viewing.
• Convincing moon landing deniers - They discussed the challenge of persuading conspiracy theorists, citing evidence including Soviet tracking confirmation and modern lunar reconnaissance photos showing Apollo landing sites.
