Doug Parkinson, a mechanical engineer from Wisconsin, now serves as NASA's SLS (Space Launch System) rocket lead for Launch Integration and Mission Operations. In this role, he guides the team responsible for monitoring the rocket during testing, pre-launch, and launch activities. Parkinson joined NASA in 1999 and has worked on advanced liquid rocket engine development, including the J-2X engine used on the Saturn V. He is the first person to hold the Launch Integration and Mission Operations leadership position in the SLS Program.

Why it matters

Parkinson's work is crucial to the success of the Artemis missions, which aim to land the first astronauts on the Moon since the Apollo program. As the lead for launch integration and mission operations, he plays a pivotal role in ensuring the SLS rocket performs as expected, paving the way for the Artemis II astronauts to fly by the Moon in the coming years.

The details

Parkinson's path to this role began when he discovered an opportunity to work at the Propulsion Research Center at the University of Alabama in Huntsville, where he studied new propulsion technologies. This experience led him to join NASA at the Marshall Space Flight Center in 1999, where he initially helped develop advanced liquid rocket engines. In 2012, he transitioned to the SLS program, leveraging his expertise in test operations to take on the role of operations lead for the stages element. Now, he also serves as one of the SLS Engineering Support Center managers, overseeing and training the team responsible for monitoring the rocket's systems during critical launch and mission phases.
