    NASA's X-59 reaches speed and altitude milestones ahead of first quiet supersonic flights

    NASA's X-59 research aircraft has achieved significant speed and altitude milestones, reaching Mach 1.4 (924 mph) and 55,000 feet. These tests are crucial steps for the upcoming Quesst mission, which aims to fly the X-59 over populated US communities. The aircraft is designed to produce a "quiet sonic thump" instead of a traditional sonic boom, and further testing will validate its acoustic signature before public overflights. AI

    NASA readies the X-59 for its first supersonic flight, SpaceX's Starship grounded and more science stories

    NASA is preparing its X-59 aircraft for its inaugural supersonic flight in early June, aiming to achieve speeds over 630 mph. The agency plans further tests to reach Mach 1.6, or 1,218 mph, at higher altitudes. Meanwhile, the FAA has grounded SpaceX's Starship program following a mishap during its latest test flight, where the Super Heavy booster failed to perform a proper boostback burn and experienced a hard splashdown.

    A successful Japanese trial of a ramjet engine designed for Mach‑5 aircraft

    Japan has successfully conducted a ground combustion trial of a ramjet engine designed for Mach-5 hypersonic aircraft. This test, a collaboration between JAXA and several universities, is a significant step towards enabling flights from Tokyo to Los Angeles in under two hours. The engine, which has no moving parts and relies on forward motion to compress air, was tested under simulated high-altitude and high-speed conditions, validating its thermal-protection system and performance.
