La nave espacial Psyche de la NASA sobrevoló Marte el 15 de mayo, utilizando la gravedad del planeta para ganar velocidad y ajustar su rumbo. La maniobra la acercó a Marte más que cualquiera de las lunas del planeta.

La nave pasó a 2,800 millas de Marte a una velocidad de 12,300 mph durante su aproximación más cercana alrededor de las 3:30 p.m. hora del Este. Esta distancia fue menor que la órbita de Fobos, que gira alrededor de Marte a 3,700 millas de distancia. El sobrevuelo fue una asistencia gravitatoria planificada diseñada para conservar el gas xenón utilizado por el sistema de propulsión iónica solar-eléctrica.

NASA's Artemis II Launches Four Astronauts on First Crewed Lunar Flyby in Over 50 Years

NASA's Artemis II mission lifted off successfully on April 1, 2026, from Kennedy Space Center in Florida, sending astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen aboard the Orion spacecraft for the first crewed Moon flyby since Apollo 17. Powered by the Space Launch System (SLS) rocket, the 10-day test flight will validate critical systems for future lunar landings and Mars missions, looping around the Moon's far side.

NASA's Psyche spacecraft set for close Mars flyby

NASA's Psyche spacecraft is scheduled to pass within 2,800 miles of Mars on May 15 to gain a gravitational boost toward its target asteroid. The maneuver will increase the probe's speed while allowing tests of its scientific instruments.

NASA releases initial Artemis II mission assessments

25 de abril de 2026 Reportado por IA

NASA has completed initial evaluations of the Artemis II mission systems following the crew's safe return from a lunar flyby earlier this month. The Orion spacecraft and SLS rocket performed as expected, setting a new record for the farthest distance traveled from Earth. Minor issues arose with the toilet system, but the crew resolved them successfully.

Artemis II astronauts fly around moon's far side

NASA's Artemis II crew became the first humans in over 50 years to loop around the moon's far side on April 6, traveling farther from Earth than any before them. The astronauts captured unprecedented views, including close-ups of craters and a unique solar eclipse. They are now heading back for a splashdown off California on April 10.

Artemis 2 astronauts begin Earth reentry

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.

Researchers test semi-autonomous legged robot for planetary surfaces

Scientists from the University of Basel, ETH Zurich, and the European Space Agency have tested a quadrupedal robot equipped with a robotic arm to explore planetary surfaces more efficiently. The robot navigated rocky terrain autonomously, identifying targets and collecting data faster than traditional human-guided methods. The findings, published this week, suggest it could accelerate resource prospecting and searches for signs of life on the moon and Mars.

Simulations probe asteroid Psyche's interior via massive crater

18 de marzo de 2026 Reportado por IA

Researchers at the University of Arizona simulated the formation of a large crater on metal-rich asteroid 16 Psyche to predict its internal structure ahead of NASA's arriving spacecraft. The study highlights the role of porosity in crater shapes and tests two possible compositions: a layered metallic core with rocky mantle or a uniform metal-silicate mix. Findings, published in JGR Planets, will aid interpretation of mission data expected in 2029.
