In a joint effort between the University of Kentucky and the University of Southern Queensland, an observation of the re-entry of the CYGNUS NG-20 spacecraft was conducted from the aircraft. HEFDiG, the High Enthalpy Flow Diagnostics Group at the IRS, took part with a new camera system. David Leiser had to travel to the other side of the world to be present during the re-entry near the Cook Islands. The event provided a unique opportunity to study the re-entry process and collect valuable data on the dynamics of spacecraft disintegration in the Earth's atmosphere. A total of 12 instruments were installed on the aircraft, allowing the team to capture videos and optical spectral signatures associated with the re-entry. The knowledge gained from this observation will improve the understanding of aerothermodynamics and ultimately optimize safety protocols for future missions. Such a scientific endeavor also underscores the importance of observation campaigns in advancing space technology and ensuring the reliability of space exploration activities.
We thank Prof. Alexandre Martin of the University of Kentucky for making this observation mission a reality, NASA for the funding, and Prof. Fabian Zander (former HEFDiG post-doc!) of the University of Southern Queensland for the mission planning.
