Video NASA engineers have launched a gigantic parachute as big as a size of a house at record speed to prepare for its Mars 2020 mission.
The object, dubbed ASPIRE (Advanced Supersonic Parachute Inflation Research Experiments), unfolded from a small cylinder to a massive parachute, weighing over 80 kilograms (180 pounds), in just four-tenths of a second.
