Meet my lead systems engineer, Kristina Larson. Despite occasionally having to wake up her team members at 3 a.m. to address spacecraft anomalies, she loves that she gets to “explore worlds that were truly new to us.”

Any time my ion engines were on, there were blue lights glowing in my mission control. My team gathered to turn them off one more time. <3 As for the science and exploration, much more to come!
