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'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.

A two-day countdown is underway for NASA's Artemis II mission, scheduled to launch four astronauts on a flight around the moon from Kennedy Space Center in Florida. Liftoff is set for a two-hour window opening at 6:24 pm EDT on Wednesday, with backup opportunities through April 6. The crew will test the Orion spacecraft on a 10-day journey, marking humans' first deep space voyage in more than 50 years.

Following their successful launch, NASA's Artemis II astronauts aboard the Orion spacecraft resolved a jammed toilet fan and Microsoft Outlook software glitches during the initial phase of their 10-day lunar orbit mission. The crew—Commander Reid Wiseman, Pilot Victor Glover, Mission Specialists Jeremy Hansen and Christina Koch—marks historic firsts: Glover as the first Black astronaut, Koch the first woman, and Hansen the first Canadian to venture toward the moon.
