Keeping Cool Under a Lunar Freeze: Rigorous Testing Prepares Starship for Extreme Temperatures
NASA is sending humans back to the moon, and a lunar landing isn’t a walk in the park. In fact, surviving the journey and departing to return -to get the details by day- the moon is no easy feat. NASA engineers at the Marshall Space Center are tackling a key challenge: how to keep everything running smoothly in the harsh environment of deep space, from scorching sunlight to freezing lunar nights.
The solution? A comprehensive thermal protection system, and a tireless quest for the perfect insulation materials. At the heart of this effort lies the HI-TTeMP (Hub for Innovative Thermal Technology Maturation and Prototyping), a dedicated laboratory

The two vacuum test chambers provide a controlled environment to model lunar conditions, where temperatures can range from a blistering 120°C in direct sunlight to a frigid -223°C during lunar nights. These extreme fluctuations pose unique challenges for any spacecraft aiming to land.
One manufacturer supporting the Artemis program is focusing on keeping their equipment operational under these extreme conditions. SpaceX’s reusable Starship, armada to ferry both cargo and astronauts to the lunar surface, are being continuously battered.

How does Starship’s thermal management system protect internal components from freezing during the frigid lunar night?
## Keeping Cool Under a Lunar Freeze: Rigorous Testing Prepares Starship for Extreme Temperatures
**Host:** Welcome back to the show. Today we’re talking about SpaceX’s Starship, the ambitious vehicle designed to transport astronauts to the Moon and Mars. Joining us is Dr. Emily Carter, athermal engineer at SpaceX. Dr. Carter, thanks for being here.
**Dr. Carter:** Thanks for having me.
**Host:** Starship is set to face some extreme temperature swings in space, from the scorching heat of reentry to the frigid cold of lunar night. Can you tell us about the challenges Starship’s design needs to overcome?
**Dr. Carter:** Absolutely. One of the biggest challenges is protecting Starship during atmospheric reentry. As the spacecraft plunges through the atmosphere, friction generates immense heat, reaching temperatures hotter than molten lava [[1](https://www.mountbonnell.info/boca-chica-blastoff/starships-heat-shield-innovating-reentry-technology)]. To withstand this, Starship is equipped with a revolutionary heat shield made from special tiles that can handle these extreme temperatures.
**Host:** That sounds incredibly advanced. And what about the cold? We know the Moon experiences extreme temperature variations.
**Dr. Carter:** You’re right. The lunar night can plunge temperatures down to -280 degrees Fahrenheit. To combat this, Starship is designed with advanced insulation and thermal management systems to regulate its internal temperature and protect critical components from freezing.
**Host:**
Fascinating. So SpaceX is essentially putting Starship through a rigorous “temperature boot camp” before its lunar missions?
**Dr. Carter:** Exactly! We’re conducting extensive ground testing simulating both the scorching heat of reentry and the frigid chill of space and the lunar surface. This testing helps us ensure that Starship’s thermal systems are robust enough to handle the extremes it will face during its missions.
**Host:**
Thank you, Dr. Carter, for giving us this behind-the-scenes look at Starship’s thermal technology. It sounds truly remarkable. And we wish SpaceX all the best as they continue their preparations for these groundbreaking missions.
