Entry, Descent and Landing Systems


Entry, Descent, and Landing, consists of four sub-technology areas: • Aeroassist and entry. • Descent. • Landing. • Vehicle systems technology. Entry, Descent and Landing (EDL) is a critical technology that enables many of NASA’s landmark missions, including Earth reentry, Moon landings, and robotic landings on Mars. The EDL topic defines entry as the phase from arrival through hypersonic flight, with descent being defined as hypersonic flight to the terminal phase of landing, and landing being from terminal descent to the final touchdown. EDL technologies can involve all three of these mission phases, or just one or two of them.
