Blue Origin is taking another stab at its first launch in 15 months as New Shepard’s 24th mission is scheduled to take flight on Tuesday. The company had to scrub a planned launch on Monday due to a ground system issue. Today’s launch window opens at 11:37AM ET and the webcast starts 20 minutes beforehand. You can watch the launch below.

The uncrewed science mission has 33 payloads, more than half of which were developed by NASA, Blue Origin says. The other payloads are from K-12 schools, universities and STEAM-centric organizations. The manifest also includes 38,000 student postcards from the Club for the Future initiative.

The Federal Aviation Administration grounded New Shepard after an uncrewed launch attempt in September 2022 didn’t go as planned. The booster failed after takeoff but it was able to separate successfully from the capsule. Although the capsule made a safe parachute landing, the booster was destroyed when it hit the ground in a designated hazard area.
