How the Falcon Heavy could revolutionize exploration of the ocean worlds

Casey Dreier • February 08, 2018 • 8

SpaceX's Falcon Heavy is not just for big payloads, it can also throw light things into space very fast. And that has significant implications for the exploration of distant destinations in our outer solar system—particularly the ocean moons of the giant planets.

No plumes? No problem. How Europa Clipper will analyze an icy moon's ocean

Jason Davis • January 11, 2018 • 4

Google Maps released several new map products that allow you to see the locations of named features on many solar system planets and non-planets, spinning them around in space with your mouse.

Voyager 40th anniversary: The transformation of the solar system

Ted Stryk • August 23, 2017 • 2

The Voyager missions transformed most of the large worlds of the solar system from points of light into places to be explored.

Congress gives NASA's planetary science division some love (and a Mars orbiter)

Jason Davis • July 19, 2017 • 1

The House of Representatives proposed $2.1 billion for NASA's planetary science budget, which would be an all-time high. Part of the increase would be used to start work on a new reconnaissance and communications orbiter.

NASA's audacious Europa missions are getting closer to reality

Jason Davis • February 21, 2017 • 10

Today, NASA announced progress on a spacecraft that would assess whether Jupiter's Moon Europa is habitable, and earlier this month, an agency-sponsored science team released a report on a separate lander mission that would directly search for signs of life.

New Findings are Conclusive: Europa is crying out for exploration

Casey Dreier • September 26, 2016 • 19

New scientific findings add to the evidence that Europa is spouting its liquid ocean into space. NASA has a mission to Europa in the works, but it wouldn't launch for at least a decade. Congress can make it faster, but it all depends on whether they can pass a budget this year.

Juno's instruments return riches from first perijove
