The solar sail Nanosail-D has sailed home, burning up in the atmosphere on September 17.
The flight phase of the mission successfully demonstrated a deorbit capability that could potentially be used to bring down decommissioned satellites and space debris by re-entering and totally burning up in the Earth’s atmosphere. The team continues to analyze the orbital data to determine how future satellites can use this new technology.
The concept being tested appears to use a solar sail as a navigating tool for guiding defunct satellites back into the atmosphere.
