RV-X memiliki panjang sekitar 7,3 meter dan diameter 1,8 meter, serta ditenagai oleh sebuah mesin yang menggunakan oksigen cair dan hidrogen cair.

Tokyo, Jepang (Xinhua/Indonesia Window) – Badan antariksa Jepang kembali membatalkan uji terbang perdana yang dijadwalkan untuk kendaraan eksperimental roket kecil yang dapat digunakan kembali (reusable), RV-X, pada Senin (30/3) karena malafungsi, menurut laporan media lokal.

Badan Eksplorasi Kedirgantaraan Jepang (Japan Aerospace Exploration Agency/JAXA) memulai persiapan prapeluncuran untuk RV-X sejak Senin pagi waktu setempat di Pusat Pengujian Roket Noshiro di Prefektur Akita. Namun, para teknisi menemukan bahwa perangkat yang dirancang untuk memisahkan pipa suplai bahan bakar dari badan roket tidak berfungsi secara normal. JAXA kemudian memutuskan untuk membatalkan uji terbang pada hari itu, menurut Kyodo News dan The Sankei Shimbun.

Upaya yang dibatalkan tersebut menandai penundaan kelima uji terbang perdana RV-X. Peluncuran awalnya dijadwalkan pada 7 Maret, tetapi ditunda tiga kali akibat faktor cuaca dan dijadwalkan ulang menjadi 25 Maret. Pada hari itu, uji coba juga dihentikan sebelum lepas landas karena perangkat yang menghubungkan badan roket dengan peralatan eksternal mengalami \"masalah yang memerlukan konfirmasi.\"

RV-X memiliki panjang sekitar 7,3 meter dan diameter 1,8 meter, serta ditenagai oleh sebuah mesin yang menggunakan oksigen cair dan hidrogen cair.

Program uji coba itu bertujuan untuk mengumpulkan data guna pengembangan roket yang dapat digunakan kembali. Jepang berencana mengadopsi teknologi reusable tersebut pada roket pengangkut utama generasi berikutnya untuk memungkinkan peluncuran satelit dengan biaya lebih murah dan frekuensi lebih sering.
