NASA moves Artemis II astronaut Christina Koch into the acting deputy chief engineer post
NASA will make astronaut Christina Koch acting deputy chief engineer on Nov. 1, ending her eligibility for future spaceflight assignments. She takes the seat Katherine Van Hooser leaves when she retires Oct. 21, and Amit Kshatriya holds the chief engineer title.

Three figures: Van Hooser's NASA service of more than 35 years, ending Oct. 21; the final 21 shuttle flights she led engineering efforts through; and 11 days between Van Hooser's last day and Koch's start date.
| Figure | Value | Note | Claim |
|---|---|---|---|
| Van Hooser's NASA service, more than | 35 years | 2 | |
| Final shuttle flights she led | 21 flights | 13 | |
| Gap until Koch starts | 11 days | 17 |
What happened
- Koch flew as a mission specialist on Artemis II in April, the first crewed flight around the Moon in more than 50 years.
- Before that she spent 328 consecutive days on the International Space Station, the longest single spaceflight by a woman, and took part in the first all-female spacewalks.
- Van Hooser was chief engineer for the space shuttle main engine and led engineering efforts through the final 21 shuttle flights.
- Van Hooser has been NASA's deputy chief engineer since 2023 and also served as chief engineer at Marshall Space Flight Center.
Why it matters
- cost The pool of flight-eligible astronauts with a flight around the Moon on their record is one smaller after Nov. 1.
- decision Isaacman tied the appointment to a lunar surface return, a Moon Base, nuclear power in space and Mars capabilities, a list that extends well past Artemis II, so the new deputy will be reviewing engineering for programs beyond the one she flew.
- precedent An astronaut who flew Artemis II in April is in engineering management within months. NASA now has a recent example of moving a flown crew member into the chief engineer's office.
Koch is the deputy. Amit Kshatriya is NASA's associate administrator and chief engineer [7], and the release says Koch will "help lead NASA's engineering community" while supporting technical oversight, mission readiness and engineering excellence across the agency's programs and projects [3]. In our view the appointment shows NASA wants operational experience in the deputy seat.
Van Hooser's career was propulsion. She joined NASA in 1991 and her early work was on liquid rocket engine turbomachinery [12]. She later became the first chief engineer for the Space Launch System's Liquid Engines Element [14]. Koch started as an electrical engineer at Goddard, developing scientific instruments, and did scientific field engineering in Antarctica and the Arctic before her 2013 selection as an astronaut [10]. She has since held leadership positions in the Astronaut Office and at Johnson Space Center [11].
Isaacman made the case in terms of vantage point. "Christina has seen NASA engineering from both sides of the equation: developing complex systems on the ground and trusting them with her life in space," he said [5]. Kshatriya said Koch "brings a unique combination of engineering expertise, operational experience, and proven leadership, both on the ground and in space" [16]. Both assessments come from the officials who made the appointment.
The release does not say whether a permanent appointment follows, or who covers the 11 days from Van Hooser's last day to Koch's start [17].
What to watch
- Whether NASA names a permanent deputy chief engineer or confirms Koch beyond the acting period.
- Whether NASA says what the deputy's portfolio covers beyond the release's three phrases on oversight, readiness and excellence.
- Whether NASA announces who fills the crew slots Koch is no longer eligible for on future lunar flights.
