Now, though, spurred by the rise of the buccaneering, private-sector "New Space" industry, which is offering access to the cosmos at prices far lower than government-backed rockets can manage, the old dream is enjoying a resurgence. Elon Musk, whose rocket firm SpaceX already flies cargo to the International Space Station (ISS), makes no secret of his Martian ambitions. Two privately run organisations in particular -Inspiration Mars, brainchild of Dennis Tito, an American tycoon who became the world's first space tourist in 2001, and Mars One, run by Bas Lansdorp, a Dutch entrepreneur - have announced plans to send people to Mars without relying on the resources of a state. Removing the requirement to land simplifies the task enormously. No complex manoeuvring into a Mars orbit is necessary. No landing craft is needed, nor any survival gear for use on the Martian surface. That saves fuel and, more importantly, launch mass (the overriding concern for any space mission). Tito's team hopes to wring further savings by launching in 2018, in order to take advantage of a rare set of celestial circumstances that allow a gravity-powered trip to Mars and back in 501 days, instead of the two years that would normally be required. That keeps food and water requirements low. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
