Mission system manager Al Cangahuala says the robotic explorer of Jupiter’s ocean moon is making steady progress toward a 2024 launch.
Our look ahead at the near-future of solar system exploration continues with Mars, the giant outer worlds, and the smaller bodies that can be found throughout the neighborhood.
Astrobotic is one of several companies that are building small, robotic landers to take commercial payloads to the surface of the Moon. With a new contract from NASA to support his company’s work, CEO John Thornton looks forward to touching down in 2021. Senior editor Emily Lakdawalla can’t wait for the Europa Clipper to reach Europa, one of Jupiter’s ocean moons. Who doesn’t want more cow bell? Chief scientist Bruce Betts gets his share as he helps us explore the current night sky in What’s Up.
magine soaring over what may be the solar system’s most Earth-like world, if you ignore the chill. If funded, the nuclear electric-powered Dragonfly will do exactly this. Principal Investigator Elizabeth “Zibi” Turtle shares her enthusiasm.
A computer model based on our best data about Saturn’s cloud-shrouded moon says that torrential liquid methane pounds the surface far more frequently than previously expected. Sean Faulk and Jonathan Mitchell of UCLA explain.
Rod Pyle reveals bizarre yet fascinating space projects of the past in his new book. Pyle also exposes previously classified information about missions and spacecraft you thought you knew.
In our third episode, we debate the risks and rewards of tying the future of a Europa mission to the fate of NASA's massive Space Launch System rocket. Also, NASA just announced that the next Mars rover will cost $2.4 billion—$900 million more than initially thought. But the mission is not considered over budget. Why not? Lastly, the U.S. just generated 50 grams of Plutonium-238, the largest amount in nearly thirty years. We celebrate the successful effort to create this critically important, though highly toxic, power source for deep space spacecraft.
John Grunsfeld closes our coverage of the Space Foundation’s 32nd annual Space Symposium in Colorado Springs. We also meet the leaders of the New Generation Space Leaders Program.
