Generally, NASA defines "high" hypersonic as any Mach number from 10 to 25, and re-entry speeds as anything greater than Mach 25. Among the spacecraft operating in these regimes are returning Soyuz and Dragon space capsules ; the previously-operated Space Shuttle ; various reusable spacecraft in development such as SpaceX Starship and Rocket ...
The NASA X-43 was an experimental unmanned hypersonic aircraft with multiple planned scale variations meant to test various aspects of hypersonic flight. It was part of the X-plane series and specifically of NASA 's Hyper-X program developed in the late 1990s. [ 1 ]
The X-15 set speed and altitude records in the 1960s, crossing the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's highest speed, 4,520 miles per hour (7,274 km/h; 2,021 m/s), [ 1 ] was achieved on 3 October 1967, [ 2 ] when William J. Knight flew at Mach 6.7 at an altitude of 102,100 feet ...
The first manufactured object to achieve hypersonic flight was the two-stage Bumper rocket, consisting of a WAC Corporal second stage set on top of a V-2 first stage. In February 1949, at White Sands, the rocket reached a speed of 8,290 km/h (5,150 mph), or about Mach 6.7. [1]
On June 26, 2018, the US Air Force informed NASA it had assigned the X-59 QueSST designation to the demonstrator. [7] By October, NASA Langley had completed [clarification needed] three weeks of wind tunnel testing of an 8%-scale model, with high AOAs up to 50° and 88° at very low speed, up from 13° in previous tunnel campaigns.

The F-100 Super Sabre and F5D had a top speed of Mach 1.4. The F-104 had a top speed of Mach 2. Flight 188's take-off was delayed by some minor problems that were fixed. A modified Boeing B-52 Stratofortress, model NB-52B, was used to take the X-15A-2 to height. The NB-52B, NASA Balls 8, carried the X-15A-2 under the right wing.
