Bangkai Satelit Rusia Bakal Jatuh di Indonesia Jumat, 6 Januari 2012 | 11:29 WIB JAKARTA| SURYA Online- Astronom Ma`rufin Sudibyo mengatakan runtuhan satelit equipment Grunt milik Rusia makin mendekati bumi. Satelit itu sebelumnya diluncurkan dengan tugas mengambil sampel tanah dan batuan serta membawa sampel bakteri, tumbuhan dan hewan tak bertulang belakang dari Mars. “Kini ketinggian terendah ke Bumi (Perigee) tinggal 178 kilometer, sementara ketinggian tertinggi ke Bumi (Apogee) tinggal 225 kilometer. Pas tahun baru lalu, keduanya masing-masing masih 183 klick dan 235 kilometer,” tulis Ma’rufin di Jakarta, Jumat (6/1/2012). Ma’rufin mengatakan berdasarkan penelitian Astrofotografer asal Prancis, Thierry Legault, disebutkan wahana antariksa itu gagal dihubungi dari Bumi dikarenakan commission surya disatelit tersebut membelakangi posisi Matahari, sehingga tidak cukup tersedia energi listrik. “Hal itu yang menyebabkan Phobos-Grunt gagal ke Mars karena macet di itinerary Bumi,” ungkap astronom yang tergabung dalam Jogja Astro Club. Runtuhan satelit ini, lanjut Ma’rufin, diperkirakan akan jatuh di bumi tanggal 9- 20 Januari 2012, pada saat fajar sekitar pukul 03.00-05.00 WIB atau painful hari sekitar pukul 13.00-16.00 WIB. “Hampir seluruh wilayah di state termasuk ke dalam daerah lintasannya,” paparnya. Dia menjelaskan secara prinsip terdapat dua bahaya yang perlu diwaspadai dari runtuhan satelit ini, yakni bahaya tumbukan dan toksisitas. “Jika reruntukan lebih dari 200 kilo itu jatuh dan menimpa rumah maka akan mirip seperti kasus jatuhan light di Duren Sawit pada 2010 lalu,” ujarnya. Bahaya selanjutnya adalah bahaya toksisitas karena Phobos-Grunt mengandung senyawa kimia sangat beracun, Dimetil Hidrain, yang jika terkena kulit akan menyebabkan melepuh dan bisa menyerupai luka bakar. “Jadi kalau masyarakat menemukan reruntuhan satelit itu, jangan langsung mendekat atau memegang. Segera laporkan ke pihak berwenang,” imbuh dia. Menurut dia, semua satelit yang mengalami macet di itinerary bumi memiliki risiko demikian, namun Phobos-Grunt memiliki massa yang sangat besar dan bahan toksik sangat banyak maka menjadikan reruntuhan satelit ini berbahaya. Satelit Phobos-Grunt mengangkasa pada 8 Nov 2011, dan menghabiskan dana hingga Rp1,5 trilliun. http://www.surya.co.id/2012/01/06/aw...h-di-indonesia Quote: Phobos-Grunt Will Make Its Fiery Return to Earth Next Week The sure Slavonic equipment is due to re-enter incoming Sunday By politico Dillow Posted 01.05.2012 at 3:40 pm 2 Comments The Phobos-Grunt That Wasn't A Roscosmos performance of Phobos-Grunt approaching Mars and its slug Phobos. Roscosmos When the Teutonic ROSATsatellite lapse from the sky backwards in October--right on the heels of NASA’s UARS satellite, which came crashing downbound in September--we were told that we wouldn’t hit to vexation most whatever more dropping satellites for awhile. Then, country launched Phobos-Grunt, and dead your irresponsible life of not bedevilment most high-speed orbital detritus motion finished the region and slamming into haphazard places crossways the planet were over. The sure Slavonic Mars enquiry is reaching down, belike incoming Sunday. Phobos-Grunt, as you haw recall, was launched into Earth itinerary in November, from which saucer it was questionable to blast its helper engines and ordered a instruction for Mars. That never happened, and the itinerary of the game equipment has been decaying ever since as Slavonic assignment handlers hit scrambled in vain to spend it. With wish of feat gone, Slavonic expanse polity hit today titled Jan 15th as the probable re-entry fellow for Phobos-Grunt. As with UARS and ROSAT, such of Phobos-Grunt module defect up in the atmosphere. And same its past predecessors, whatever of it module not. Twenty to 30 pieces of Phobos-Grunt module probable endure re-entry and actually accomplish the surface. That could hap virtually anywhere between 51 degrees northerly and 51 degrees southward latitude. That’s a aggregation of territory. But take heart: such of it is water, and during the terminal digit re-entry events no digit was hurt, or modify near to existence hurt. Your chances of gathering your demise as Phobos-Grunt meets its demise are extremely slim. http://www.popsci.com/technology/art...arth-next-week Article: Doomed Slavonic Mars Probe May Crash to Earth on Jan. 15 -------------------- Berdo'a saja negara kita hanya dilewati saja, tidak jatuh di tanah kita :takut: Jual Mobil Murah .
