MSL Entry, Descent & Landing Instrument Suite (MEDLI)

"The heights by great men reached and kept were not attained by sudden flight, but they, while their companions slept, were toiling upward in the night."
-- Henry Wadsworth Longfellow, 19th-century American poet

When the Mars Science Laboratory mission, or MSL -- the latest entry in NASA's Mars Exploration Program -- reached the red planet in August 2012 to deliver an advanced new science rover, Curiosity, to the surface, NASA researchers also were closely studying a complex instrumentation payload in the entry vehicle's heatshield. Its successful results could significantly influence how we send future robotic and human missions to Mars.

The MSL Entry, Descent, & Landing Instrument suite, or MEDLI, is a NASA Technology Demonstration Mission, a set of engineering sensors designed to measure the atmospheric conditions and performance of the entry vehicle's heatshield during atmospheric entry and descent. While not part of the core scientific payload of the Mars Science Laboratory, the instrument suite provided important engineering data for the design of entry systems for future planetary missions.

The MSL Entry, Descent, & Landing Instrument suite was designed and developed by NASA's Langley Research Center in Hampton, Va., in partnership with NASA's Ames Research Center in Moffett Field, Calif.
