Muter-muter pakai piring terbang, ke bulan cuma 6 jam Kawans, Beragam cerita tentang piring terbang yang mengangkut aliens ke bumi masih jadi tanda tanya besar. Buat sebagian orang, mereka cuma sekadar penampakan. Entah itu fakta atau fantasi, namun ada kabar baik: NASA sedang merancang sebuah piring terbang yang dapat mengangkut 12 orang.
Mau mengelilingi bumi? Atau terbang menuju bulan? Konon cuma dibutuhkan waktu 6 jam lamanya. Memang, untuk ukuran ET, masa tempuhnya masih terlalu lama. Tapi siapa tahu, suatu saat nanti manusia (NASA) dapat menyempurnakannya menjadi hanya 5 menit? Lagi-lagi ini sebuah tantangan buat kita semua. Berita ini saya cuplik berita dari BBC Science & Nature (baca artikel di bawah). NASA bikin segala macam 'benda aneh' itu bukannya tak punya tujuan: selain untuk menyibak rahasia alam semesta, juga untuk lebih mengangkat harkat dan martabat bangsa. Bangsa Amerika yang selalu ingin memposisikan diri sebagai 'super power' tentu saja, bukan kita. Mustinya, langkah-langkah yang dilakukan NASA tak bikin kita jadi minder. Tak bikin kita patah semangat. Tapi memacu kita untuk dapat selangkah, bahkan seratus langkah lebih maju. Nah, ini tantangan buat kita semua orang Indonesia! Kenapa para ahli aeronautika kita kok melempem? Bikin pabrik helikopter saja kok malah bangkrut, padahal cuma 'tukang jahit'. Saya sarankan kepada para karyawan IPTN (dan para teknisi Indonesia), daripada terus menerus demo yang menghabiskan energi, mending bikin 'moter' (mobil terbang). Ini sebuah terobosan yang belum digarap negara-negara maju (paling tidak belum dirilis). Membuat mobil terbang tak susah kan? Lagian biayanya tak sebesar merancang piring terbang, toh bisa pakai mobil bekas. Syukur-syukur bisa kerjasama dengan perusahaan otomotif. Saya prediksi, 'moter' akan jadi trend di tahun 2050-an. Kehadiran moter jelas akan mengurangi kepadatan lalu lintas darat, dan juga mengurangi polusi karena moter menggunakan bahan bakar yang ramah lingkungan. Ayo, ayo, cepat bikin, lalu patenkan. Ada kendala birokrasi? Terhambat aturan undang-undang? Ayo demo ke DPR! Tuntut DPR untuk memangkas aturan-aturan yang tak perlu - yang bikin bangsa ini tambah melempem saja. Hadirnya moter di Indonesia, paling tidak dapat mengangkat harkat dan martabat bangsa Indonesia. Kalau kita bisanya cuma mengkonsumsi produk- produk ciptaan luar negeri tanpa berupaya berinovasi, kapan kita bisa jadi bangsa yang maju dan mandiri? Terus terang, selama ini kita masih saja 'dijajah' bangsa lain, dari mulai cara berpikir, pilihan gaya hidup, ekonomi, politik, penyedotan sumber daya alam, dan tak lama lagi mereka akan masuki relung-relung kehidupan sosial dan penggencetan budaya. Jadi, kita sebetulnya belum merdeka 100%, bung! Salam Merdeka!

Whatever your opinion, new saucer designs could be set to send us into space. Since the age of the 1950s B-movies, flying saucers have been the vehicle of choice for any discerning alien. Looking like a cross between a metal hubcap and a glow-in-the-dark frisbee, these strange spacecraft have fascinated us for decades. Whether you accept Area 51 or reject the Roswell Incident, there's still a chance you may see a flying saucer in the not too distant future. However, rather than carrying extra-terrestrials from other planets, the saucer could be transporting you round the Earth or even to the Moon. Lightcraft The 'Lightcraft' is the latest in alternative spacecraft design and has been built by Leik Myrabo of Rensselaer Polytechnic Institute. Powered by infrared lasers, the shiny surface reflects and focuses this laser beam into a ring. The surrounding air heats up to a temperature 5 times hotter than the surface of the Sun and then explodes, thrusting the saucer forward. The advantage of this power system is that the Lightcraft doesn't need to carry onboard fuel; the laser light could be beamed up from Earth. However, before you start booking yourself in for a spin, the ship is only 15cm across and climbs just 30m in three seconds. Drawbacks of the Lightcraft Currently, the craft is very small and noisy, but NASA has drawn up a design plan for a 20m microwave-powered saucer, carrying up to 12 people to the Moon in just six hours. The power supply would be harvested by solar panels, housed on a lunar orbiting power station. After converting this solar energy into microwaves, these waves would be beamed straight to the Lightcraft to power its lunar trip. Once the saucer nears its destination, the crew would have to slow the ship down by steering through a series of ring-shaped electromagnets on the Moon, before touching down on the lunar surface. Outlandish it may sound, but the scientific principles behind the craft have already been demonstrated and the technologies are within reach. However, only the brave would take the test flight. The crew on the prototype craft would need to be encased in liquid-filled escape pods to protect them from the extreme G-forces they would experience. Our best bet for travelling deeper into space is to get out the cosmic compass and set sail for the stars.
