TWiS 95: Clean Energy From Space With John Mankins - The Future of Space-Based Solar Power

1h 6m · Published 26 Jan 22:30

Climate change has become a top priority for all of us, including NASA. Space solar power—beaming energy from space 24 hours per day—has become a real possibility and is being studied internationally by the US, Europe, Japan, and China. It promises to provide a zero-emissions, zero-carbon source of energy worldwide—but it will take significant investment, development, and commitment. A recent NASA-backed study was positive but careful with its conclusions, and John Mankins, one of the first researchers of SSP in the US who continues to work on the concept, joins us to address the report and to talk about the possible future of limitless, clean, and affordable energy for a hungry world.

Headlines:

  • Mars Ingenuity Helicopter - After a highly successful demonstration flight campaign on Mars with over 70 flights, NASA has announced the pioneering helicopter can no longer fly due to damage sustained to its rotors during its last flight. Despite this setback, Ingenuity has proven that flight is possible on Mars and paved the way for future rotorcraft explorers.
  • SLIM Lander - Japan's SLIM lunar lander achieved a soft landing on the moon but tipped over on its side during touchdown, limiting its ability to collect science data. Still, Japan is hailing the mission as a success for proving precise landing capabilities that can be applied to future missions.
  • Exoplanet Discovery - The Hubble Space Telescope has discovered a new "hot and steamy" exoplanet called GJ 9872d that harbors water vapor in its atmosphere, making scientists excited about its potential to host life even though surface temperatures exceed 700°C.


Main Topic: Space-Based Solar Power

  • Benefits - Space solar power collected in space and beamed wirelessly to Earth is carbon-neutral, available 24/7, and faces no weather disruptions, providing a major clean energy source.
  • Viability - The core concept is scientifically sound and uses proven technology like satellites and wireless transmission. Recent advancements in areas like reusable rockets, modular hardware, and efficient solar cells have made costs far more viable.
  • NASA Study - A recent NASA-commissioned study reached lackluster conclusions about economic feasibility, but used assumptions counter to emerging launch trends on achievable costs for launches and hardware production.
  • International Competition - Other nations like China, Japan, and Europe are investing much more in research and planning than the US currently is, challenging the US to regain leadership in space solar power.
  • Safety - Wireless power transmission systems can be designed to safely beam microwaves at intensities less than natural sunlight.
  • SPS-ALPHA Concept - Modular design using sophisticated tracking mirrors, "sandwich modules" of solar panels, electronics, and transmitters. Features mirrors to keep panels illuminated as satellite orbits. Built of mass-produced, interchangeable parts requiring no new technology.
  • Path Forward - Continue incremental technology advancements and on-orbit demonstrations to build confidence. Involve commercial space companies that can leverage economies of scale. Stress US origins of the concept and opportunity to lead in developing this carbon-free energy source.

TWiS 93: Does America Really Want to Go Back to the Moon? - With Former NASA Historian Roger Launius

1h 10m · Published 12 Jan 23:00

America's heading back to the Moon, but what does the public really think? This week, we talk with former NASA Chief Historian and Smithsonian Curator Dr. Roger Launius, who has studied, among many other things, public perceptions of NASA and spaceflight. Some spoilers: no, there was no "Golden Age" in the 1960s when the public was hugely behind the Apollo Moon landings; being a space historian is a lot of fun; and it probably doesn't really matter if China lands people on the Moon before the US does so *again*. Join us.

Headlines:
• Successful first flight of ULA's new Vulcan Centaur rocket with engines from Blue Origin
• Payload - Astrobotic's Peregrine commercial lunar lander suffers propulsion leak en route to the Moon
• NASA engineers finally open stuck cover on OSIRIS-REx asteroid sample capsule

Main Topic: Public Perceptions of Space Exploration
• Common perception of widespread public support and national unity around Apollo program is a myth
• Polls at the time showed concerns about cost and other spending priorities
• Support depended heavily on Cold War context; would not have happened otherwise
• Public support and approval polling for space exploration has remained fairly consistent over decades
• But support drops when funds are weighed against other priorities like social programs
• JFK tried multiple times to make Apollo a joint U.S.-Soviet program to save money
• His assassination allowed NASA to leverage his legacy to maintain support and funding
• Presidential bold visions for space require an urgent political problem to address
• Competition with China lacks the existential threat of the Cold War space race

Additional Topics:
• NASA is now doing business with more private-public and commercial partnerships
• But political factors and election cycles still hamper long-term continuity
• Preserving history and archives from the digital era will be extremely difficult
• Predictions: Boots on the Moon again within 10-15 years, Mars by 2040s
