ABL's RS1 Rocket Destroyed in Launchpad Fire

ABL Space Systems, a startup founded in 2017, experienced a significant setback with the destruction of its RS1 rocket during preflight testing. The rocket, designed for small-satellite launches, suffered irreparable damage from a fire that broke out following a static fire test on July 19, 2023, at the Pacific Spaceport Complex in Alaska. The fire was traced to a restrictive launch mount and flame deflector, which caused plume recirculation and overloaded the rocket’s base heat shield, leading to the shutdown of all nine first-stage engines.

This incident follows a previous failed attempt in January 2023, where the RS1 rocket also did not reach orbit and exploded after its engines shut down shortly after liftoff. Despite these challenges, ABL Space Systems continues to develop its two-stage RS1 rocket, which is capable of delivering up to 1,350 kg of payload to low Earth orbit at a cost of $12 million per launch. The company has identified 22 corrective actions to address the issues and prevent future failures.

In addition to dealing with technical setbacks, ABL Space Systems has secured substantial financial backing and business contracts. The company received a $60 million Strategic Funding Increment from the U.S. Space Force and U.K. Air Force in March 2023 to demonstrate its tactical response capabilities. Lockheed Martin, a significant investor and customer, has plans for up to 58 RS1 launches. Despite the recent setbacks, ABL Space Systems remains committed to advancing its launch capabilities and fulfilling its contracts.
