    "They found that while the robot can leap to a height of 1.5 metres, such leaps put stresses on the robot's legs that make it more likely to fall over. Leaping to 0.8 metres improved stability but reduced the robot's maximum running speed. Future simulations will determine the precise trade-off between speed and stability."

SpaceX launcher

  • 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.
