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.
While LightSail 1 and 2 look nearly identical at a glance, there are a few important hardware differences between the two spacecraft.

LightSail 2’s launch window opens on June 22, and we are finalizing plans for our launch viewing celebrations. Once we have finished coordinating the details with the Air Force’s STP-2 mission team and the Kennedy Space Center, we will share them with all of our members and backers so that you can join us in person or remotely via the internet.
The Planetary Society's solar sail spacecraft will lift off 22 June 2019 on a mission to demonstrate the power of sunlight for propulsion.
The Planetary Society's solar sailing CubeSat is officially on the road to launch.
SpaceX also went three-for-three on booster landings, marking another milestone for its Falcon Heavy rocket.
Bruce Betts reports on LightSail 2’s status and looks to the future of solar sailing.
An Air Force official says an ‘initial launch capability’ is being reassessed.
Two NASA CubeSats are approaching Mars — an impressive accomplishment for a concept many people regarded with derision just 15 years ago.
On February 6, 2018, I found myself shoulder to shoulder with two of my heroes: Bill Nye on the left, Buzz Aldrin on the right. Our eyes were fixed on the first vertical Falcon Heavy rocket. Figuring the world's most powerful rocket might send me flying backwards once the countdown hit zero, I gripped the railing so tightly I started to lose the feeling in my fingertips.
LightSail 2's ride to space won't happen until at least November 30, as SpaceX works through a list of other payloads in line to fly first.
The LightSail 2 team gathered in Cal Poly San Luis Obispo for a Mission Readiness Review (MRR) and Operational Readiness Test (ORT).
