Which mission did NASA tests Supersonic Parachute recently?
A
Mars 2020 mission
B
Pioneer 10
C
Neutron star Interior Composition Explorer (NICER)
D
Roentgen Satellite (ROSAT)
Explanation: 

Detailed explanation-1: -NASA Rocket Launch Tests Supersonic Parachute for Mars Rover Landings. NASA successfully tested a supersonic parachute designed to land the agency’s next rover on Mars today (Sept. 7) during a sounding rocket flight from Wallops Island in Virginia.

Detailed explanation-2: -(AP)-The huge parachute used by NASA’s Perseverance rover to land on Mars contained a secret message, thanks to a puzzle lover on the spacecraft team. Systems engineer Ian Clark used a binary code to spell out “Dare Mighty Things” in the orange and white strips of the 70-foot (21-meter) parachute.

Detailed explanation-3: -Orion’s parachute system is designed to ensure a safe landing for astronauts returning to Earth in the crew module at speeds exceeding 25, 000 mph from deep space missions.

Detailed explanation-4: -Supersonic parachutes have been used as aerodynamic decelerators during entry and decent into low-density atmospheres, e.g., for Mars space exploration missions. Owing to their low mass and high packaging efficiency, they provide a highly efficient means of deceleration from supersonic to subsonic speeds.

Detailed explanation-5: -Tiverton-based textiles company Heathcoat Fabrics has made the parachute that will help land the US space agency’s Perseverance rover, which is looking to uncover traces of ancient life and collect soil and rock samples for examination back on Earth.
