How NASA Tests Spacecraft Reentry

NASA tests re-entry heat shield materials and Hypersonic air flows using the arcjet complex.

• The arcjet works by creating an arc to turn air into plasma, which can simulate re-entry conditions.
• The arcjet can reach temperatures up to 30,000°F and is made of copper due to its high thermal conductivity.
• Different heat shield materials, such as Avcoat and Adept, are tested for re-entry scenarios.
• Foldable heat shields like Adept are being developed for Mars entry.

Wind Tunnel Evaluation

The unitary plan wind tunnel at NASA is used to evaluate wind tunnel models for various applications.

• Techniques like shadow graph, infrared thermography, pressure-sensitive paint, and oil flow are used to evaluate model performance.
• The wind tunnel facility has a rich history dating back to the NACA in the 1950s and has been used for various programs.

Gratitude

• The video creator expresses gratitude to NASA, Scott Manley, and the research center for the opportunity to tour the facility.
