Stories, updates, insights, and original analysis from The Planetary Society.
Extraordinary claims require extraordinary evidence, so here are the reasons why there may or may not be aliens in our cosmic backyard.
Arecibo helped us explore the cosmos and our solar system, search for life, and defend Earth from potentially dangerous asteroids.
The last time was a test. This time it was for real. SpaceX successfully launched 4 astronauts to the International Space Station on 15 November 2020.
NASA's OSIRIS-REx successfully collected a sample from asteroid Bennu on 20 October 2020.
PlanetVac, developed by Honeybee Robotics, is designed to be a reliable, flexible, low-cost sample collection technology.
The kilometer-wide object won't hit Earth, but would cause global-scale devastation if it did.
Every 6 months, we ask our recent Planetary Society Shoemaker NEO Grant winners for a progress report. Here's what they told us.
A new paper recaps mission events, discusses solar sail performance, and describes how the spacecraft's orbit has changed.
The Center for Solar System Studies, a perennial Planetary Society Shoemaker NEO Grant winner, is a small observatory that makes big contributions to near-Earth asteroid research.
Thanks to our members and donors, The Planetary Society participated in several activities at the 2019 International Astronautical Conference.
More than 50,000 people supported LightSail 2. But only one person can talk to the spacecraft at a time, and it's often a student.
The yet-to-be-named telescope would launch as soon as 2024, as part of NASA's new, multi-pronged approach to planetary defense.
When LightSail 2 recently flew south of The Planetary Society's headquarters, CEO Bill Nye and other staff members stepped outside to listen.
Astrophysicist Karl Battams tells us what we can learn by studying objects from outside our solar system.
Communications were lost with the lander, which was carrying a small rover named Pragyan to the lunar surface.
We've got 2 fish-eye pictures of the spacecraft's solar sail from opposite cameras, and we're hoping they can be combined.
Japan's sample return spacecraft only has about 3 months left at asteroid Ryugu. Its next action will be to drop more stuff on the surface.
LightSail 2's orbital high point around the Earth has raised by 7.2 kilometers, without any conventional fuel.
Last week, technicians installed the carousel that holds the tools and drill bits that will be used to collect samples for future return to Earth.
The combination lander, rover, and orbiter fired its main engine to enter orbit around the Moon at 09:02 IST (03:32 UTC) on 20 August.
