Wahana antariksa Psyche milik NASA melintasi Mars pada 15 Mei, menggunakan gravitasi planet tersebut untuk menambah kecepatan dan menyesuaikan jalurnya. Manuver ini membawanya lebih dekat ke Mars dibandingkan kedua bulan planet tersebut.

Wahana antariksa ini melintas dalam jarak 2.800 mil dari Mars dengan kecepatan 12.300 mph saat titik terdekatnya sekitar pukul 15.30 waktu Timur. Jarak ini lebih dekat daripada orbit Phobos, yang mengelilingi Mars dari jarak 3.700 mil. Lintas terbang ini merupakan bantuan gravitasi terencana yang dirancang untuk menghemat gas xenon yang digunakan oleh sistem pendorong ion surya-listrik.

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

Sabtu, 25 April 2026 Dilaporkan oleh AI

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

Rabu, 18 Maret 2026 Dilaporkan oleh AI

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.
