Gearing up for its first flight test, NASA's Adaptable Deployable Entry Placement Technology, or ADEPT, is no ordinary umbrella. ADEPT is a foldable device that opens to make a round, rigid heat shield, called an aeroshell. This game-changing technology could squeeze a heat shield into a rocket with a diameter larger than the rocket itself. The design may someday deliver much larger payloads to planetary surfaces than is currently possible.
Spacecraft typically approach planets at speeds tens of thousands of miles per hour —screaming fast. Entering a planet's atmosphere at those speeds compresses atmospheric gas, creating pressure shock and generating intense heat right in front of the spacecraft.
Aeroshells - Spacecraft - Entry - Heat - ADEPT
Aeroshells slow spacecraft during entry and shield them from heat. ADEPT could be key to future NASA missions that require extra-large aeroshells to protect spacecraft destined to land on the surface of other planets, all without requiring larger rockets.
ADEPT's first flight test is scheduled for Sept. 12 from Spaceport America in New Mexico aboard an UP Aerospace suborbital SpaceLoft rocket. ADEPT will launch in a stowed configuration, resembling a folded umbrella, and then separate from the rocket in space and unfold 60 miles above Earth.
Test - Minutes - Launch - Earth - Return
The test will last about 15 minutes from launch to Earth return. The peak speed during the test is expected to be three times the speed of sound, about 2,300 miles per hour. That is not fast enough to generate significant heat during descent, but the purpose of the...
