The technology to reach another planet or moon is only worth and so much if you can't land on it. Every landing has its own challenges, but celestial bodies with an atmosphere are particularly vexing. For decades, the heat shields that protect spacecraft during atmospheric entry take been rigid and heavy, simply NASA only tested a flexible "umbrella-like" heat shield that could brand deep space missions more than practical.

The flexible heat shield is known every bit the Adjustable Deployable Entry and Placement Applied science (ADEPT), and it was adult at NASA'south Ames Research Center in California. NASA'southward goal is to brand heat shields larger while also reducing weight — it's an area of spacecraft design long overdue for a change.

Spacecraft are moving at fantastic speeds when they descend to the surface, and that compresses atmospheric gas. The compression causes pressure level shock, leading to intense heating in front of the spacecraft as high as 5,400 degrees Fahrenheit (3,000 Celsius). Even a sparse temper similar the ane on Mars can cause significant heat buildup. Current spacecraft utilise aeroshells to keep the payload cool as information technology enters an atmosphere. Aeroshells are usually made of thick phenolic plastic and ablates (peels away) under intense heat to protect the spacecraft. The plastic isn't flexible and weighs quite a lot. Thus, heat shields can't be larger than the bore of the rocket that launched them.

Skilful could change all that. It's composed of layers of 3D woven carbon fabric stretched over articulating ribs and struts. Rather than ablating, Proficient re-radiates absorbed heat with very high efficiency to keep the payload cool. Because it'south flexible, the shield can fold up to fit inside a rocket, then deploy to cover a much larger surface area. Proficient could help larger spacecraft slow down and avoid heat impairment during atmospheric entry.

The exam flying on September 12th involved a quick 15-infinitesimal sub-orbital flight. The rocket lifted the prototype to an altitude of lx miles (technically in space) and released it. Good traveled as fast equally Mach 3 (2,300 mph), which is slower than it would be moving when entering the atmosphere from space. However, this test was primarily concerned with assessing the engineering science and aerodynamics.

With the first exam flight in the books, NASA says the next footstep for ADEPT is re-entering the Earth's atmosphere at orbital speeds in excess of 17,000 mph (27,000 kph). The agency has all the same to set a engagement for that test.
