"Wet" Asteroids Could Supply Space Gas Stations
FleaPlus writes "Water ice was recently discovered on the large asteroid 24 Themis, and Space.com discusses proposals for producing fuel from asteroid ice. NASA and the President recently announced plans for robotic precursor missions to asteroids (and a human mission by 2025), as well as a funding boost for R&D to develop techniques like in-situ resource utilization. Since most of the mass of a beyond-Earth mission is fuel, refueling in orbit would be a huge mass- and cost-saver for space exploration (especially if fuel can be produced in space), but a large unknown is how to effectively extract water in an environment lacking gravity." -
NASA Prepping Plans For Flexible Path To Mars
FleaPlus writes "A group at NASA has been formulating a 'Flexible Path' to Mars architecture, which many expect will be part of the soon-to-be-announced reboot of NASA's future plans. NASA's prior architecture spends much of its budget on creating two in-house rockets, the Ares I and V, and would yield no beyond-LEO human activity until a lunar landing sometime in the 2030s. In contrast, the Flexible Path would produce results sooner, using NASA's limited budget to develop and gain experience with the technologies (human and robotic) needed to progressively explore and establish waypoints at Lagrange points, near-Earth asteroids, the Martian moon Phobos, Mars, and other possible locations (e.g. the Moon, Venus flyby). Suggested interim goals include constructing giant telescopes in deep space, learning how to protect Earth from asteroids, establishing in-space propellant depots, and harvesting resources/fuel from asteroids and Phobos to supply Moon/Mars-bound vehicles." -
Ares Manager Steve Cook Resigns From NASA
FleaPlus writes "Steve Cook, project manager for the Ares I-X, Ares I, and Ares V rockets, announced that he will resign from NASA MSFC after 19 years at the agency, leaving for an executive position at Dynetics, Inc. This raises doubts about the future of the Ares program, which has been plagued with development problems and massive cost/schedule overruns since its inception. Steve Cook also oversaw the (since discredited) 2005 ESAS study which scrapped NASA's prior plans to adapt already-existing commercial rockets for human/beyond-LEO exploration in favor of internally developing the Ares rockets."
