Stories, updates, insights, and original analysis from The Planetary Society.
All the latest space news, plus ways you can celebrate and advocate for space.
One year after launch, The Planetary Society’s solar sail spacecraft is embarking on an extended mission dedicated to further advancing solar sailing technology.
Images from around the globe, plus some night pictures and the spacecraft's solar panels.
Celebrating Shoemaker Grant winners, Society awards, and volunteer efforts around the world.
A new paper recaps mission events, discusses solar sail performance, and describes how the spacecraft's orbit has changed.
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.
When LightSail 2 recently flew south of The Planetary Society's headquarters, CEO Bill Nye and other staff members stepped outside to listen.
We've got 2 fish-eye pictures of the spacecraft's solar sail from opposite cameras, and we're hoping they can be combined.
Your LightSail 2 spacecraft is in space, controlling its orbit solely on the power of sunlight.
A new issue of The Planetary Report brings you our pride in the success of LightSail 2 and our gratitude to our members for making it happen. Plus Venus science from Akatsuki and Venus Express, and the status of planetary defense.
LightSail 2's orbital high point around the Earth has raised by 7.2 kilometers, without any conventional fuel.
If your latitude is within 42 degrees of the equator, there's a chance you may be able to spot LightSail 2's reflective solar sail.
The high point of the spacecraft's orbit around the Earth on Monday was 729 kilometers, an increase of 3.2 kilometers since sail deployment.
In the past 4 days, the spacecraft has raised its orbital high point, or apogee, by about 2 kilometers.
Images from The Planetary Society's spacecraft confirm the solar sails deployed on 23 July 2019 at 11:47 PDT (18:47 UTC).
The target ground station pass for deployment starts 23 July 2019 at roughly 11:22 PDT (18:22 UTC).
Visit planetary.org/live for video and audio from mission control, located at Cal Poly San Luis Obispo in California.
Spare bandwidth during ground station passes has allowed flight controllers to downlink 2 new high-resolution images.
Sail deployment is now scheduled for no earlier than 21 July 2019.
