Your LightSail 2 spacecraft is in space, controlling its orbit solely on the power of sunlight.
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.
Pictures taken by the spacecraft's cameras Friday evening show a crescent Earth, as LightSail 2 heads into orbital sunset.
Would you like to see the latest data from The Planetary Society's LightSail 2 spacecraft—possibly before flight controllers have even seen it? Now you can!
The mission team is working through a 73-step checklist to check out the spacecraft’s systems and perform various tests.
The mission team received LightSail 2's first signals on 2 July at 01:34 PDT (08:34 UTC), as the spacecraft passed over Cal Poly San Luis Obispo in California.
The Planetary Society's solar sail CubeSat lifted off from Kennedy Space Center, Florida on 25 June at 02:30 EDT (06:30 UTC).
The Planetary Society's solar sailing spacecraft is ready to take flight. We got an up-close look at its ride to orbit.
LightSail 2 is one of 24 spacecraft hitching a ride to orbit as part of the U.S. Air Force's STP-2 mission.
Our preview guide outlines the LightSail 2 mission from start to finish.
LightSail 2 is launching on the next SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy Space Center in Florida. It is one payload of many on the mission known collectively as STP-2. Space Test Program (STP) is a crucial part of the US Air Force’s development of advanced technologies in space.
The official launch date is now no earlier than June 24th, and the launch window still opens at 11:30 p.m. eastern time.
