Target peluncuran Artemis II mundur ke 1 April setelah masalah helium picu penarikan roket

NASA menunda misi Artemis II hingga 1 April setelah masalah aliran helium yang menyebabkan roket ditarik kembali dari landasan peluncuran, melanjutkan perbaikan sebelumnya untuk kebocoran hidrogen selama uji pengisian bahan bakar. Orbit Bulan berawak pertama sejak 1972 ini menghadapi pemeliharaan berkelanjutan sebelum kembali ke lokasi peluncuran.

Setelah uji pengisian bahan bakar Wet Dress Rehearsal yang sukses pada pertengahan Februari—setelah kemunduran kebocoran hidrogen awal—Artemis II mengalami masalah baru pada 22 Februari. Tim darat tidak dapat mengalirkan helium ke tahap atas roket Space Launch System (SLS) selama persiapan di Kennedy Space Center. SLS setinggi 322 kaki (98 meter) ditarik kembali ke Vehicle Assembly Building pada 25 Februari. Pemeriksaan mengungkap segel yang lepas di quick disconnect, menghalangi aliran helium. Tim membongkar, memperbaiki, dan menguji sistem pada laju aliran yang dikurangi. «Para insinyur sedang menilai apa yang menyebabkan segel tersebut lepas untuk mencegah terulang,›› kata NASA. Saat berada di gedung perakitan, teknisi melakukan pemeliharaan: mengaktifkan baterai sistem terminasi penerbangan, mengganti baterai di berbagai tahap dan booster, mengisi ulang baterai sistem abort Orion, dan mengganti segel oksigen cair tahap inti. Roket tidak akan kembali ke Launch Complex 39B hingga akhir Maret. Jendela peluncuran dibuka pada 1 April pukul 18.24 EDT (22.24 UTC) selama dua jam, dengan cadangan pada 3-6 April. Artemis II akan mengirim empat astronot—komandan Reid Wiseman, pilot Victor Glover, spesialis misi Christina Koch, dan Jeremy Hansen—keliling sisi jauh Bulan menggunakan Orion, menguji sistem untuk pendaratan pada 2028. Ini memperbarui target sebelumnya pada 6 Maret yang ditetapkan setelah sukses pengisian bahan bakar.

NASA's Artemis II crew—commander Reid Wiseman, pilot Victor Glover, mission specialists Christina Koch and Jeremy Hansen—is in quarantine at Kennedy Space Center, with the Space Launch System rocket returned to the pad after repairs. Launch opportunities open as early as April 1 for the first human lunar trip since 1972, featuring a flyby of the moon's far side.

NASA has set March 6 as the earliest possible launch date for the Artemis II mission following a successful second fueling test of its Space Launch System rocket. The test at Kennedy Space Center resolved issues from an earlier attempt marred by a hydrogen leak. The mission will send four astronauts around the Moon in a crewed test of the Orion spacecraft.

NASA has begun a critical two-day wet dress rehearsal for the Artemis II mission at Kennedy Space Center, simulating launch procedures without engine ignition. The test involves loading the Space Launch System rocket with over 700,000 gallons of propellant and could pave the way for a crewed launch as early as February 8. This marks preparation for the first human trip beyond low Earth orbit since 1972.

Fifty-eight years after Apollo 8's lunar orbit, Nasa is set to launch Artemis II, a crewed flyby that will take astronauts farther from Earth than ever before. The mission will test key technologies for future lunar landings and mark a step toward a permanent moon base. The crew, currently in quarantine, includes commander Reid Wiseman, pilot Victor Glover, and mission specialists Christina Koch and Jeremy Hansen.

NASA's Artemis II astronauts have surpassed the halfway point to the Moon following Wednesday's translunar injection burn, continuing smooth progress on the historic 10-day mission—the first crewed trip beyond low Earth orbit since Apollo 17. The crew is on track for a lunar far-side flyby tomorrow and observations on April 6.

NASA's Artemis II astronauts are returning to Earth after a 10-day journey to the far side of the moon, with splashdown scheduled for Friday evening. The agency will livestream the historic homecoming. NASA administrator Jared Isaacman stated that the mission is not over until everyone arrives home safely.

NASA has canceled the Exploration Upper Stage for its Space Launch System rocket as part of a major revision to the Artemis program. The decision, announced by Administrator Jared Isaacman, aims to accelerate lunar landings by focusing on surface activities and using more efficient upper stages. This move supports testing of human landers from SpaceX and Blue Origin ahead of missions in 2027 and 2028.
