Ingenieros de la NASA logran un avance en rotores supersónicos para helicópteros en Marte

Ingenieros del Laboratorio de Propulsión a Chorro de la NASA han probado con éxito palas de rotor más grandes que giran a mayor velocidad que la del sonido sin romperse. El hito, anunciado este jueves, aumenta la capacidad de sustentación en un 30 por ciento para futuras misiones a Marte.

Las pruebas se llevaron a cabo en una cámara que simulaba la tenue atmósfera de Marte, donde las puntas de los rotores alcanzaron Mach 1.08. Los ingenieros del JPL y AeroVironment utilizaron diseños tanto de tres como de dos palas, siendo este último el que coincide con la configuración prevista para la misión SkyFall. Un ventilador dentro de la cámara simulaba vientos en contra a medida que aumentaban las velocidades, y el equipo observó los resultados desde una sala de control cercana.

Orion spacecraft from Artemis 2 mission has completed its final maneuver before atmospheric reentry, the most critical phase of the journey. Astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen face a 13-minute descent at over 40,000 km/h and temperatures above 2,500 degrees, with splashdown planned off San Diego.

NASA announced on Tuesday that it will pause development of the Gateway lunar space station and repurpose its Power and Propulsion Element for SR-1 Freedom, a nuclear-electric propulsion demonstration mission to Mars launching before the end of 2028. The spacecraft will carry Skyfall helicopters to scout subsurface water ice and landing sites. Officials described the move as leveraging existing hardware to prove nuclear power in deep space.

Chinese scientists have developed revolutionary software capable of fully simulating the extreme physics of supersonic fuel combustion in just one week. Previously, the same task could take a supercomputer years to complete. It modelled internal dynamics across hundreds of millions of computational cells, more than 20 times the resolution typical of current global research.

Blue Origin achieved a milestone by successfully landing and reusing the first stage of its New Glenn rocket for the third flight, but the upper stage failed to place its payload into the correct orbit. The launch occurred Sunday from Cape Canaveral Space Force Station in Florida. The booster, named Never Tell Me The Odds, touched down on a ship in the Atlantic Ocean after its second flight.

NASA's Artemis II mission, the first crewed flight of the Orion spacecraft around the Moon since 1972, has encountered a helium leak in its service module but officials say it poses no threat to the crew's return. The spacecraft, carrying astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen, launched on April 1 and is set for splashdown in the Pacific Ocean on Friday evening. Ground teams adjusted the flight plan to study the leak while maintaining nominal performance.

A 14-year-old boy from China's Hainan Island has drawn public attention for reportedly handcrafting a turbojet engine in his family's living room. State media outlets have portrayed Che Jingang as a self-taught engineer, with his mother's social media account boasting 30,000 followers. The teenager, who calls himself 'rocket boy,' dismisses skepticism about his skills.

Bavarian space company Isar Aerospace cancelled its latest test flight attempt of the Spectrum carrier rocket from Norway's Andøya spaceport on Thursday, suspecting a leak in a pressure container. This follows an abort on March 25 due to a safety issue. CEO Daniel Metzler promised another attempt soon.
