Watch NASA Test Its New Supersonic Parachute at 1300 Miles Per Hour

NASA’s latest Mars rover is headed for the Red Planet in 2020, and the space agency is working hard to make sure its $2.1 billion project will land safely. When the Mars 2020 rover enters the Martian atmosphere, it’ll be assisted by a brand-new, advanced parachute system that’s a joy to watch in action, as a new video of its first test flight shows.

Spotted by Gizmodo, the video was taken in early October at NASA’s Wallops Flight Facility in Virginia. Narrated by the technical lead from the test flight, the Jet Propulsion Laboratory’s Ian Clark, the two-and-a-half-minute video shows the 30-mile-high launch of a rocket carrying the new, supersonic parachute.

The 100-pound, Kevlar-based parachute unfurls at almost 100 miles an hour, and when it is entirely deployed, it’s moving at almost 1300 miles an hour—1.8 times the speed of sound. To be able to slow the spacecraft down as it enters the Martian atmosphere, the parachute generates almost 35,000 pounds of drag force.

For those of us watching at home, the video is just eye candy. But NASA researchers use it to monitor how the fabric moves, how the parachute unfurls and inflates, and how uniform the motion is, checking to see that everything is in order. The test flight ends with the payload crashing into the ocean, but it won’t be the last time the parachute takes flight in the coming months. More test flights are scheduled to ensure that everything is ready for liftoff in 2020.

How to See August’s Full Sturgeon Moon

This summer has been an especially exciting time for avid sky-gazers—the NEOWISE comet flew close to Earth in mid-July, and the ongoing Perseid meteor shower is gearing up for its peak around August 11. Though full moons aren’t quite as rare, the sight of a glowing white orb illuminating the night is still worth a glance out your window.

When Is August’s Full Moon?

As The Old Farmer’s Almanac reports, the eighth full moon of 2020 will reach its peak at 11:59 a.m. EST on Monday, August 3. If that’s daytime where you live, you’ll have to wait for the sun to set that night, or you can catch it the night before—Sunday, August 2.

Why Is It Called a Sturgeon Moon?

Each month’s full moon has a nickname (or multiple nicknames), usually of folk origin, that coincides with certain plant, animal, or weather activity common at that time of year. January’s full moon, for example, was named the “wolf moon” because wolves were said to howl more often during January. June’s “strawberry moon” occurred when strawberries were ripe and ready to be picked.

Since people caught an abundance of sturgeon—a large freshwater fish that’s been around since the Mesozoic era—in the Great Lakes and Lake Champlain during this part of summer, they started calling August’s full moon the sturgeon moon. It has a few lesser-known monikers, too, including the “full green corn moon” (a nod to the approaching harvest season), and the slightly wordy “moon when all things ripen.”
