Into the Anthropocosmos is MIT Space Exploration Initiative director Ariel Ekblaw’s collection of innovations that will improve life in space and on Earth.
Spacecraft need a navigation and communication infrastructure to carry out their missions. Learn how NASA does it and what’s in store for the future.
Here’s our sampling of the leading edge research presented by NIAC Fellows at NASA’s 2021 virtual gathering.
NASA engineer and scientist Troy Hudson shares the sad but ultimately inspiring story of a two-year attempt to dig deep beneath the surface of Mars.
We examine a few of the thousands of technologies and innovations developed by NASA that are making lives better around our planet.
NASA has given the green light to Principal Investigator Les Johnson and his team for construction of a solar sail that dwarfs all that have come before.
Join us as the little cubesat successfully unfurls its solar sail! You’ll hear from members of the LightSail 2 mission team on the morning of July 23, 2019, when the critical command was sent to the spacecraft.
A giant SpaceX Falcon Heavy lifted off in the early hours of June 25th. One week later, the LightSail 2 solar sail was released to begin its epic mission. You’ll join the thrilling launch, meet LightSail team members and leaders of other missions, and get a solar sail update in this very special episode.
The day is almost here. With the launch of a Falcon Heavy rocket, The Planetary Society will begin its mission to prove that a tiny, orbiting spacecraft can be propelled by the light of the Sun.
LightSail 2 is not the only solar sail in the universe. NASA’s Marshall Space Flight Center and the Jet Propulsion Lab are preparing to send NEA Scout on a long, light-propelled journey to a near Earth asteroid.
The co-founder and Executive Director Emeritus of The Planetary Society returns for a conversation about the allure of sailing through space.
The Planetary Society’s LightSail 2 solar sail spacecraft is ready to be packed away for its ride to orbit on a SpaceX Falcon Heavy rocket. Mat Kaplan checks the mission’s status with team members.
Philip Lubin and his former student Travis Brashears have had quite a year. Their bold plan to send tiny probes to nearby stars is now supported by NASA and the Breakthrough Starshot $100 million dollar initiative. Hear their amazing story.
The Planetary Society’s solar sail spacecraft was in the middle of a critical test as we spoke with the Society’s Bruce Betts and Jason Davis.
LightSail, the Planetary Society’s innovative solar sail cubesat, will ride into space on the huge SpaceX Falcon Heavy, now in development. Bill Nye and others join us for a live celebration of this announcement.
There’s so much we don’t know about the origin of life here or anywhere else in the universe. But there must have been an energy source. Researcher Laurie Barge led work that simulated the natural formation of a fuel cell that may have taken place in Earth’s primordial oceans.
The successful launch of MAVEN was covered by Mat Kaplan, Bruce Betts and Emily Lakdawalla, with special, launch site reports from Jim Bell and Bill Nye.
Casey Dreier tells the winding tale of Plutonium 238, the radioactive isotope that is vital for exploration of the solar system. The US came dangerously close to exhausting its supply. Even with production restarted, there are major challenges facing explorers.
Only days after Voyager 1 reached interstellar space, forward thinkers met in Houston, Texas to consider how humans can become a starfaring species. Planetary Society Emeritus Executive Director Lou Friedman reports from the meeting.
We pay another visit to the queen of planets with Cassini Mission Project Scientist Linda Spilker. She always brings us fascinating news from Saturn, its moons and rings.
