Perjalanan Keangkasa (Bag 2)

PERJALANAN KE ANGKASA
(Bagian 2)



Pada bagian akhir abad ke-20, mimpi manusia itu tampak mulai menjadi kenyataan. Roket kuat membawa kendaraan — berawak dan tidak berawak — ke angkasa telah dikirim. Astronaut dan atau kosmonot pun telah mengunjungi bulan.


Disamping itu sejak tahun 1977 ESA (European Space Agency) –  selain Rusia (USSR) dan Amerika Serikat (USA) – telah ikut serta dalam perjalanan ke ruang angkasa. Seperti diketahui  ESA pada 20 April 1977 telah mengirim GEOS 1 untuk study tentang magnetism di atmosfere bumi, seperti tampak pada daftar berikut ini.

Pada bagian akhir abad ke-20, mimpi manusia itu tampak mulai menjadi kenyataan. Roket kuat yang membawa kendaraan — berawak dan tidak berawak — ke angkasa telah dikirim. Astronaut mengunjungi bulan. Pesawat ruang angkasa berawak dan stasiun ruang angkasa menjalankan  misi yang mengorbit bumi tampak hampir dilakukan secara rutin. Manusia, hewan, dan tumbuhan telah dikirim ke angkasa. Hal itu menandakan bahwa manusia tidak lagi semata-mata hidup dibumi. Era perjalanan dan eksplorasi ruang angkasa telah dimulai.


Pada 12 April 1961. Yuri Gagarin, seorang kosmonot Soviet Rusia, menjadi orang pertama yang melakukan perjalanan di luar angkasa. Pesawat ruang angkasanya, Vostok I, membuat satu orbit mengelilingi bumi dan kemudian kembali mendarat di bumi.


Yuri Gagarin

Dimuka telah dikemukakan bahwa kendaraan-kendaraan tidak berawak (tanpa manusia) dikirim ke luar angkasa antara tahun 1957 sampai tahun 1978. Dan sejak tahun 1961 sampai tahun 1986 juga telah dikirim kendaraan yang berawak,  berikut ini adalah daftar sejumlah misi ke luar angkasa yang menggunakan kendaraan berawak pada periode tersebut.

Pada 12 April 1961. Yuri Gagarin, seorang kosmonot Soviet Rusia, menjadi orang pertama yang melakukan perjalanan di luar angkasa. Pesawat ruang angkasanya, Vostok I, membuat satu orbit mengelilingi bumi dan kemudian kembali mendarat ke bumi dengan selamat.

Neil Armstrong

Pada periode tahun 1966 – 1969 ini tercatat dua peristiwa yang penting yaitu : (1) Manusia (Aldrin dari Gemini 12) terbukti dapat bekerja untuk waktu yang cukup lama (5.5 jam) di angkasa ; dan (2) Untuk pertama kalinya pesawat berawak (Apollo 11 dengan Armstrong dan Aldrin)  dapat mendarat  di bulan. Armstrong dan Aldrin berada di permukaan bulan selama 2 jam, mereka mengumpulkan batuan dan memasang instrumen.  

Namun dalam periode tersebut, pada bulan April 1967, telah terjadi kecelakaan dimana kosmonout Russia Komarov (Soyuz 1) meninggal dunia pada saat berada di angkasa (bersambung).

I think we all want to really live good lives, and we all really want to have a healthy planet, although I don't know if we're supposed to be on it forever. Now, does that mean that we should be building rocket ships to shoot us into outer space? Well if we can, I think we should (Anne Hathaway).
