Sepenggal Cerita Satelit Palapa A-1

Nama indonesia mendunia setelah memiliki satelit komunikasi domestik Palapa-A1 yang diorbitkan Juli 1976 oleh badan antariksa amerika serikat (Nasa) dari kennedy space center, florida. Peresmian penggunaannya baru 17 agustus 1976, bertepatan HUT kemerdekaan ri ke-31. Pilihan membeli satelit dianggap keputusan tepat saat itu karena indonesia adalah negara kepulauan terpanjang di dunia dengan penduduk 130 juta jiwa (terbesar kelima saat itu).

Teknologi satelit buatan Boeing Satellite Systems ini identik dengan satelit Anik dan Westar milik Kanada dan amerika pada saat itu. Bahkan roket peluncurnya pun sama, yakni Delta 2914. Menariknya, pemerintah baru memesan awal februari 1975, berupa dua satelit (dengan Palapa A2), satu pusat pengendali, dan sembilan stasiun bumi. Walhasil, Boeing hanya punya waktu 17 bulan, yang kabarnya menjadi proyek tercepat yang pernah dikerjakan perusahaan dari chicago itu.

Satelit ini tingginya 3,5 m dan diameter 2 m. beratnya saat diluncurkan mencapai 574 kg, namun menjadi 297 kg di orbit. Palapa A-1 baru berhenti beroperasi Mei 1985 atau hampir dua tahun dari waktu yang seharusnya. Sementara Palapa A-2 yang diluncurkan Maret 1977, baru berhenti januari 1988 atau empat tahun dari masa operasi idealnya.

    Grab some of these specially-made cake pans to create the fanciest cake for a loved-one’s birthday or for any
    special occasion. Though made of silicon, some of them are also made
    with other metals with a non-stick coat on the outer side.
    Get creative with your decorating options:
    experiment with icing flavours-try strawberry for Dora’s pink shirt or
    orange for her shorts. When it is baked the
    ridges made by the tin will show you where to place certain extras.

    Another trick to floor the guests would be to serve these cakes in different flavors.
