Well, we waited, we waffled, and we joked... but Boeing's Starliner finally made good! Seven or so years after their projected crewed flight date, the second provider of crew delivery to the International Space Station finally succeeded in sending two astronauts, Butch Wilmore and Sunita Williams, to the ISS. Despite a few problems with (sigh) valves, helium tanks, and thrusters, the mission appears to be going swimmingly. Then, just a day later, SpaceX launched a Starship on a fourth test flight with spectacular results--and may be ready for another test launch within a few weeks. All good news this week, and it feels like newspace just picked up a lot of steam. Join us!

This week we've invited JPL's Chief Engineer Emeritus, Rob Manning, back to discuss Mars exploration and, in particular, Mars Sample Return. As we discussed in episode 107, that project is in a bit of trouble. Rob was the Chief Engineer of every Mars rover up through Perseverance and the overall Chief Engineer on Perseverance, and he has some unique insights on how we have explored Mars, why it matters, and what the future holds... especially with regard to returning samples to Earth. Join us!

Headlines:

NASA held a press conference to explain the latest delays with Boeing's Starliner spacecraft, which stem from issues with a helium leak and concerns about the reaction control thrusters that could lead to a loss of redundancy during reentry
The European Space Agency's Euclid Space Telescope returned its first science images, providing stunning new views of galaxies never seen in such detail before to help unlock the mysteries of dark matter and dark energy
Main Topic - Mars Exploration and Sample Return:

Rob Manning recounts his extensive experience with Mars exploration at JPL, from the Sojourner rover and Pathfinder lander in the 90s to the currently operating Curiosity and Perseverance rovers
Curiosity confirmed the past presence of water on Mars, while Perseverance is collecting carefully selected rock samples to eventually be returned to Earth
The Mars Sample Return mission would bring pristine samples back to Earth for in-depth study, but is an extremely complex and costly endeavor facing budget challenges and potential delays
Rob explains why returning samples is so critical - context is key and current meteorite samples have been altered by their journey to Earth, whereas carefully selected samples could reveal much more about Mars' history and potential for life
Challenges for Mars Sample Return include the large size of the lander, the need for new parachute and guidance technologies, and planetary protection requirements to prevent contaminating Earth
NASA currently has no plans for additional Mars missions beyond sample return, and faces a potential loss of institutional knowledge as a "quiet period" approaches, highlighting the need to maintain momentum in Mars exploration

Welcome to the Big Glass Wars! That's right, just when you thought you'd heard it all, turns out there's hot competition among a few countries to stay on the cutting edge of optical astronomy, and to do that, you need a great big hunk of glass to gather light from distant galaxies and stellar systems. Enter the Carnegie Observatories and their partners on the Thirty Meter Telescope and the Giant Magellan Telescope. Both are currently under construction, and both are threatened by budget parsimony from the U.S. Congress. Dr. John Mulchaey, Director of the Carnegie Observatories, joins us to discuss what's happening, why it matters, and what you can do to help maintain U.S. leadership in astronomy, cosmology, and other STEM-related fields.

Headlines:

Boeing's Starliner launch to the ISS delayed again, this time due to a helium leak in the service module. The launch is now targeted for no earlier than May 21st.
Blue Origin plans to conduct its first crewed suborbital flight since August 2022 on May 19th, carrying six passengers including the first Black astronaut candidate Ed Dwight.
A massive sunspot caused spectacular auroras visible as far south as Alabama and turned skies purple and orange. More solar activity is expected as another large sunspot emerges.


Main Topic: The Big Glass Wars with Dr. John Mulchaey

Dr. Mulchaey provides an overview of the Carnegie Observatories, founded in 1904, and their historic telescopes at Mount Wilson that helped launch modern astronomy.
He discusses the need for extremely large next-generation ground-based telescopes, the Giant Magellan Telescope (GMT) and Thirty Meter Telescope (TMT), to study earth-like exoplanets and the early universe.
These ambitious segmented mirror telescopes will be 5-10 times larger than today's biggest telescopes and cost billions of dollars to construct.
While substantial private funding has been raised, the projects need investment from the National Science Foundation (NSF) and the U.S. government to be completed. However, the NSF has proposed only partial funding.
Dr. Mulchaey emphasizes the importance of the U.S. having both telescope projects to provide full-sky coverage, double the observation time, and maintain the nation's leadership in astronomy research or risk losing top talent to competing projects in Europe and China.
He notes that delaying a decision on full funding is causing the estimated costs to escalate as the projects are forced to wait.
Dr. Mulchaey argues passionately that inspiring the next generation of scientists and engineers by investing in these telescopes is critical for the country's future productivity and innovation.
