Last week, our CEO Bill Nye joined The President of the United States for an Earth Day visit to The Everglades, one of the country's renowned National Parks and a vital global ecosystem. The Washington Post covered the news, and we at The Planetary Society shared in the excitement.

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.

In the two months since I last checked up on the Rosetta mission, the comet has heated up, displaying more and more jet activity. Rosetta completed very close flybys on February 14 and March 28, taking amazing photos. But comet dust is making navigation difficult, so the mission is now keeping a respectful distance from the comet and replanning its future path.

Astronomers have known for a long time that Pluto’s surface is reddish, so where did the common idea that Pluto is blue come from?

Over the past couple of decades the Parkes Radio Telescope in Australia has been picking up two types of mysterious signals, each lasting just a few milliseconds. The source of one of these signals may have finally been found—and an unexpected source at that.

In 2015, The Planetary Society awarded $53,250 as part of its Gene Shoemaker Near Earth Object (NEO) Grant Program. The grants were made to a group of international researchers to find, track, and characterize potentially hazardous NEOs.

PROCYON (PRoximate Object Close flYby with Optical Navigation) is a microsatellite that launched on December 3 as a secondary payload with Hayabusa2. The mission has now selected their asteroid flyby target -- a binary asteroid named 2000 DP107 -- but is reporting a problem with their ion engines.

NASA officials have asked their European counterparts if they would like to propose contributing a small probe to NASA's Europa mission planned for the mid-2020s.

Since I last wrote about Curiosity drilling at Pink Cliffs, the rover has visited and studied two major sites, drilling at one of them. It has also suffered a short in the drill percussion mechanism that presents serious enough risk to warrant a moratorium on drill use until engineers develop a plan to continue to operate it safely.
