A poignant article by Senator Mark Kelly on how ensuring a continued American presence in space is crucial to keeping our country’s engine of science and innovation moving.
Be part of history! On Oct. 5–6, join 250+ space enthusiasts and 12+ partner organizations in Washington, D.C. as we advocate for NASA Science directly to Congress. The Day of Action is your chance to stand up for the future of space. ⏳ Registration closes Sept. 30: www.planetary.org/advocacy/day...
JUST IN! Congress is considering a stopgap bill to keep the government open through Nov. 20. OMB is planning to cut billions from NASA during this, risking paid-for missions and thousands of jobs. Tell Congress to protect NASA science and prevent these cuts: www.planetary.org/advocacy-act...
As New Horizons marks its 10-year anniversary of the Pluto flyby, it’s a bittersweet milestone. The mission, which made headlines globally, now faces the threat of being shut down mid-flight due to proposed NASA budget cuts. Learn about the Pluto flyby: www.planetary.org/articles/ten...
🚀 New tool alert: Track NASA science mission funding month by month. The White House proposed deep cuts, but Congress hasn’t decided yet — leaving missions in limbo. Compare this year’s spending to last year’s and spot early drops that could mean trouble. www.planetary.org/mission-spen...
Our efforts are WORKING to Save NASA Science! This is a huge step, but the work is not over. Thank you to everyone who wrote to your Reps, signed our petition, shared our updates, or spoke to a friend. Keep contacting Congress, we are almost to the finish line. www.planetary.org/press-releas...
Humanity can bring these samples back, but the White House is considering abandoning the mission. Tell Congress they must act and pass timely appropriations for NASA to prevent a funding gap: www.planetary.org/advocacy-act...
Live in the U.S.? We’re organizing in-person meetings for you to speak directly with your elected officials in Washington, D.C. October 5–6, join us and nearly a dozen partner organizations for the Day of Action to save NASA’s space science. Make your voice heard. www.planetary.org/advocacy/day...
BREAKING NEWS: NASA has found a potential sign of past life on Mars. www.nasa.gov/news-release...
What’s really at stake if NASA’s science budget gets slashed and entire science missions are canceled? We asked the scientists leading those missions, and their stories reveal what we all stand to lose. Here’s what they told us: www.planetary.org/articles/sci...
