Dennis Tito's 2018 Mars Mission To Be Manned 233

Last Thursday, we discussed news that millionaire Dennis Tito was planning a private mission to Mars in 2018, but details were sparse. Now, reader RocketAcademy writes that Tito has provided more information about the tip, and that he intends the mission to be manned: "Dennis Tito, the first citizen space explorer to visit the International Space Station, has created the Inspiration Mars Foundation to raise funds for an even more dramatic mission: a human flyby of the planet Mars. Tito, a former JPL rocket scientist who later founded the investment firm Wilshire Associates, proposes to send two Americans — a man and a woman — on a 501-day roundtrip mission which would launch on January 5, 2018. Technical details of the mission can be found in a feasibility analysis (PDF), which Tito is scheduled to present at the IEEE Aerospace Conference in March. Former NASA flight surgeon Dr. Jonathon Clark, who is developing innovative ways of dealing with radiation exposure during the mission, called the flight 'an Apollo 8 moment for the next generation.'"

Spinning Black Hole's Edge Rotates At Nearly the Speed of Light 227

astroengine writes "Astronomers have directly measured the spin of a black hole for the first time by detecting the mind-bending relativistic effects that warp space-time at the very edge of its event horizon. By monitoring X-ray emissions from iron ions (iron atoms with some electrons missing) trapped in the black hole's accretion disk, the rapidly-rotating inner edge of the disk of hot material has provided direct information about how fast the black hole is spinning. Astronomers used NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) — that was launched into Earth orbit in June 2012 — and the European observatory XMM-Newton measured X-ray radiation as a tool to directly infer the spin of NGC 1365's black hole. 'What excites me is the fact that we are able to do this for the very massive black holes at the centers of galaxies but we can also make the same measurement for black holes in our galaxy ... black holes that resulted from the explosion of a star ... The fact we can extend this from billions of solar masses to 10 solar masses is pretty cool,' Fiona Harrison, professor of physics and astronomy at the California Institute of Technology, Pasadena, Calif., and principal investigator of the NuSTAR mission, told Discovery News."

Software Lets Scientists Assemble DNA 149

Velcroman1 writes "Biochemical engineers can now download a piece of software and with a few simple clicks, assemble the DNA for new life forms through their laptops. 'With the proper computer tools, biologists can write their own genetic code — and then turn that code into life,' said biochemist Omri Amirav-Drory, who founded Genome Compiler Corp., the company that sells the software. He demonstrated at a coffee shop early one morning by manipulating a bacteria's genes on his laptop. The synthetic biology app is still in beta; on Jan. 15, the company added an undo feature and support for new DNA file formats. Building creatures is increasingly like word processing, it would seem. But such is the strange reality in the age of cheap genome sequencing, DNA synthesizing and 'bioinformatics.'"

What the scientists have in their briefcases is terrifying. -- Nikita Khruschev
