Stories, updates, insights, and original analysis from The Planetary Society.
Spacecraft need power to reach the dark, dusty, distant locales of our solar system. Safe, non-weapons-grade plutonium-238 provides that power when solar energy can't cut it.
Take a look at distant worlds, far-out views of the cosmos, and even some remote possibilities with this week’s scoop on space news and solar system history.

LightSail 2’s launch window opens on June 22, and we are finalizing plans for our launch viewing celebrations. Once we have finished coordinating the details with the Air Force’s STP-2 mission team and the Kennedy Space Center, we will share them with all of our members and backers so that you can join us in person or remotely via the internet.
The next time its solar sail is deployed, NEA Scout will be out near the Moon.
A Canadian Space Agency proposal would install a solar sail on the outside of the Deep Space Gateway, a miniature space station in lunar orbit.
When SLS launches Orion to the moon in 2018, a fleet of deep space CubeSats will come along for the ride, including a solar sailing spacecraft similar to LightSail.
With the shortage of plutonium-238 to power space missions, Europe has decided to focus on an accessible alternative material that could power future spacecraft: americium-241.
Van Kane rounds up some recent planetary mission concepts based on CubeSat technology.
I’m excited to report some big news on The Planetary Society’s LightSail project: actual launch dates on actual launch vehicles!

ASRGs could have stretched NASA's limited supply of plutonium to potentially enable missions to the perpetually-shadowed polar craters on our moon, to flyby Uranus, or to float for months on a Titan lake.
The Advanced Stirling Radioisotope Program (ASRG) was just cancelled by NASA. This was to be the saving grace for Plutonium-238 availability, as it was a much more efficient way to generate electricity than classic RTG systems.
We report on the current state of Plutonium-238 production in the United States, a crucial fuel source for planetary exploration spacecraft.
Society Advocacy and Outreach Coordinator Casey Dreier visits Planetary Radio with the tale of an element that is essential to exploration of deep space.
Plutonium-238 provides electricity to deep space missions, but NASA only has a little bit left. A new article in Wired highlights the disastrous consequences of no plutonium for use in space, something the Planetary Society is currently fighting for in Washington, D.C.
A large asteroid is passing reasonably close to Earth in a few hours, and astronomers at the great radio telescopes at Goldstone and Arecibo are zapping it. The latest discovery: QE2, like many asteroids, is a binary.
Chris Biddy from Stellar Exploration Inc. presented information about our LightSail project at the 2012 Aerospace Mechanisms Symposium.
The city of Tustin is about an hour's drive from Planetary Society HQ in Pasadena. That's when the freeway gods are kind, which they never are. The trip I made there yesterday was well worth the trouble.
