من إعداد الذكاء الاصطناعي

حلقّت مركبة سايكي الفضائية التابعة لوكالة ناسا بالقرب من المريخ في 15 مايو، مستخدمة جاذبية الكوكب لاكتساب السرعة وتعديل مسارها. وقد جعلتها هذه المناورة أقرب إلى المريخ من أي من قمري الكوكب.

مرت المركبة الفضائية على مسافة 2800 ميل من المريخ بسرعة 12300 ميل في الساعة خلال أقرب نقطة اقتراب لها في حوالي الساعة 3:30 مساءً بتوقيت شرق الولايات المتحدة. كانت هذه المسافة أقرب من مدار فوبوس، الذي يدور حول المريخ على بعد 3700 ميل. كانت عملية التحليق هذه مناورة مخططاً لها للاستفادة من الجاذبية بهدف الحفاظ على غاز الزينون المستخدم في نظام الدفع الأيوني الكهربائي الشمسي.

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 أبريل، 2026 من إعداد الذكاء الاصطناعي

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

10 أبريل، 2026 من إعداد الذكاء الاصطناعي

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 مارس، 2026 من إعداد الذكاء الاصطناعي

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.
