    It is possible, and NEOs may offer interesting ressources, but there is nothing in that paper. Why do they use the Sun-Earth system and not the Earth-Moon? The condition C>C1 is very weak and would have been much better had it been applied to the Earth-Moon system.

    The Space Launch System will be NASA's first exploration-class vehicle since the Saturn V took American astronauts to the moon over 40 years ago. With its superior lift capability, the SLS will allow us to explore cis-lunar space, near-Earth asteroids, Mars and its moons and beyond.

  • If whatever hit Jupiter — and astronomers might never know what it was — had instead struck Earth, it would have caused catastrophic damage to human civilization.

  • He then went on to remind the press that his company’s goal is to continue to lower the cost of access to space because high launch costs were “the fundamental factor preventing humanity from becoming a spacefaring civilization.”
  • First, two Falcon Heavy launches could field a return to the Moon
  • Second, a single Falcon Heavy could launch a Mars sample return mission.
  • ...3 more annotations...
  • Also possible with a single launch: a first ever human mission to an asteroid.
  • what effect Falcon Heavy might have on the costs of supporting the International Space Station. The ability to launch twice the supply capacity provided by the shuttle at something on the order of 20 percent of the cost changes the calculus entirely. So much so in fact, it opens the door for contemplating an entirely different future for ISS in which it never follows Mir into the Pacific.
  • Following conclusions offered by the Augustine Committee, the Obama Administration cancelled Project Constellation as unaffordable under existing budget limits, and supported instead the ambling, but cost-contained “flexible path.” If the Falcon Heavy is available, however, the rationale for selecting the flexible path—because it’s the only thing we can afford—simply doesn’t exist.

    First peer review study about he criticality of rare-earth metals. It can be read "They found that supply limits for many metals critical in the emerging electronics sector (including gallium and selenium) are the result of supply risks. The environmental implications of mining and processing present the greatest challenges with platinum-group metals, gold, and mercury. For steel alloying elements (including chromium and niobium) and elements used in high-temperature alloys (tungsten and molybdenum), the greatest vulnerabilities are associated with supply restrictions" Questions about estimation apart, this can be a valuable market for asteroid mining.. (ot just more market for Infinium-like companies http://www.technologyreview.com/news/527526/a-cleaner-cheaper-way-to-make-metals/).
