Engineer Brooke Harper has spent the last four and a half years making sure that the Mars lander InSight would make a graceful descent on the red planet. When the day finally came on Nov. 26 for InSight to land, she recalled feeling “extremely tense” in Mission Control.
When the announcer declared that InSight had landed, engineers and scientists celebrated. Harper and her colleague, Gene Bonfiglio, performed a touchdown dance, which was caught on NASA’s livestream camera. The elaborate routine has drawn widespread public attention to the mission.
