THE PLANETARY SOCIETY

Our members and supporters are part of a team. Together we want to explore other worlds, find life in the universe, and defend the Earth from dangerous asteroids. Thank you! We couldn't do it without your help.

Carl Sagan dreamed of solar sailing before founding The Planetary Society in 1980. Now our members have helped us fulfill that dream. ----------------------- "Subscribe to our YouTube Channel: http://planet.ly/ytsubscribe Follow us!

Bob Stephens from California tracks and characterizes dangerous near-Earth asteroids. The equipment needed for such a task doesn't last forever. With help from our members, asteroid hunters can upgrade their equipment to make sure we find asteroids before they find us.

Our friends at the Big Bear Solar Observatory east of Los Angeles shared this video of Mercury transiting the Sun on 11 November 2019. The patterns you see in the background are granules on the Sun's photosphere that have temperatures of about 10,000 degrees Fahrenheit (5,400 degrees Celsius)!

MASCOT fell for 6 minutes, struck a rock, and went tumbling across the surface like a dice in slow motion, finally coming to a rest on its side 7 minutes later.

This video shows brief highlights from LightSail 2, a crowdfunded space mission by The Planetary Society launching in June 2019. LightSail 2 aims to become the first spacecraft in Earth orbit propelled solely by sunlight. The goal is to raise LightSail 2’s orbit by a measurable amount, showing that solar sailing is a viable means of propulsion for CubeSats—small, standardized spacecraft that are part of a global effort to lower the cost of space exploration.

For centuries, people have dreamed of using solar sails to travel the cosmos. In 2019, The Planetary Society's LightSail 2 will help make that dream a reality by attempting the first, controlled solar sail flight in Earth orbit. The spacecraft was made possible thanks to the generous support of space enthusiasts from around the world. Launching soon aboard a SpaceX Falcon Heavy rocket.

Thanks to you, our advocacy work with the U.S. Congress and the White House has led to steady budget increases for NASA and Planetary Science since 2014. This past year, we helped establish the Planetary Science Congressional Congress which grew to 32 members. It has just been re-established for the new Congress now in session, and we want to grow it even more. This is critical because we lost some of our greatest champions of space exploration from both political parties in last fall’s election. With 111 freshmen members in Congress, your help is vital to rebuilding a strong coalition in Washington D.C.! It’s time to take action! First, we’re raising $200,000 to push forward with critical space advocacy priorities this year. And, to get us there, a generous anonymous donor has pledged $100,000 for a 1:1 match for all gifts up to that amount. Second, we’ll ask you to sign our petition to Congress, encouraging all members to: •Join the Planetary Science Congressional Caucus •Continue growing NASA’s budget by at least 5% •Support NASA initiatives to send humans beyond Earth orbit, to explore Mars and other high-priority destinations, and to support the search for life Help us create a new movement for space and exploration - please make a gift today!

On November 1, 2018, NASA announced that Dawn had run out of fuel. It is no longer able to point its radio antenna to Earth, so the mission has ended. The Planetary Society congratulates NASA, the Jet Propulsion Laboratory, and the international Dawn science mission team on an extraordinarily successful 11 years of exploration. We look forward to many years more of great science from Dawn's precious data. Thank you for making these remote parts of our cosmos more known.
