“We learn a lot each time [a launch] happens,” Chojnacki said.
Chojnacki’s work history includes numerous roles in the Space Launch System (SLS) program, which oversees the development of a massive rocket of the same name that is being built by a handful of traditional aerospace primes. The first SLS rocket launched the Artemis I mission in December 2023, and future rockets will launch the subsequent missions under the Artemis program. No part of the rocket is reusable, however, so NASA is spending upwards of $2 billion on each launch vehicle.
