Several potential future missions outlined in decadal surveys, crewed exploration mission studies, and other supporting analyses have ed/edl (entry and descent or entry, descent, and landing) architectures: mars sample return, high-speed crewed return, high-mass mars landers, and venus and gas/ice giant probes.
8 kilometers per second (15,400 miles per hour), the spacecraft will enter the upper fringe of mars' atmosphere some 33 to 37 seconds later. Onboard accelerometers, sensitive enough to detect g forces as little as 3/100ths of earth's gravity, will sense when friction from the atmosphere causes.
Entry, descent, and landing (edl) systems is a critical technology that enables many of nasa’s landmark missions, including earth reentry, manned moon-landings, and robotic landings on mars. Edl technologies support all of the systems and demonstration thereof necessary to perform any or all of the three mission phases defined by entry.

Entry, descent and landing (edl) - nasa mars entry, descent, and landing entry, descent, and landing – often referred to as edl – is the shortest and most intense phase of the mars 2020 mission. It begins when the spacecraft reaches the top of the martian atmosphere, travelling nearly 12,500 miles per hour (20,000 kilometers per hour).
Hence our ultimate aim is to protect lander modules and their instruments over the defective landing.
Entry, descent, and landing for the mars science laboratory mission included a combination of technologies inherited from past nasa mars missions, as well as exciting new technologies.
Entry, descent, and landing – often referred to as “edl” – is the shortest and most intense phase of the mars 2020 mission. It begins when the spacecraft reaches the top of the martian atmosphere, traveling nearly 12,500 miles per hour (20,000 kilometers per hour).

Entry, descent, and landing, or edl, begins when the spacecraft reaches the top of the martian atmosphere, traveling nearly 12,500 mph (20,000 kph). It ends about seven minutes later, with perseverance stationary on the martian surface. Perseverance handles everything on its own during this process.

Jul 28, 2020 since the early viking missions, nasa langley has led the agency for entry, descent and landing (edl) simulations.
Joel levine: viking was the first spacecraft to reach the surface of mars, and be an operational spacecraft. And the key challenge and the reason everyone failed before viking is called entry, descent, and landing (edl). The spacecraft enters the atmosphere of mars about 100 miles above the surface, traveling at about 18,000 miles per hour.

The sbir focus area of entry, descent and landing (edl) includes the suite of technologies for atmospheric entry as well as descent and landing on both atmospheric and non-atmospheric bodies. Edl mission segments are used in both robotic planetary science missions and human exploration missions beyond low earth orbit, and some technologies have.
For entry, descent, and landing, the mission inherited much from its martian predecessors, viking and mars pathfinder. In order to slow the spacecraft down, the mission uses inherited parachute technology from the viking missions of the late 1970s, which translated well for 1997's mars pathfinder mission.
