    In similar story (http://www.orlandosentinel.com/news/os-spacex-rocket-elon-musk-20110405,0,3234336.story) the quote: " "This is a rocket of truly huge scale," said Musk, adding it would have the capability to one day enable moon or Mars missions." tells a lot about the ambition of it...

    even bigger booster also coming: China Aims To Build World's Largest Rocket "Back in March, China revealed it is studying the feasibility of designing the most powerful carrier rocket in history for making a manned moon landing and exploring deep space, according to Liang Xiaohong, vice head of the China Academy of Launch Vehicle Technology. The rocket is envisaged to have a payload of 130 tonnes, five times larger than that of China's current largest rocket. This rocket, if built, will eclipse the 53 tonne capacity of the planned Falcon 9 Heavy from SpaceX. It will even surpass the largest rocket ever built, the 119-tonne Saturn V."

    still only "is studying the feasibility of designing a powerful carrier rocket" - we could easily do the same at no cost almost ... but still ... they might be serious ...

    The SpaceX Falcon 9 explosion was caused by a failed strut that allowed a helium bottle to burst free inside the rocket's liquid oxygen tank, CEO Elon Musk said Monday. "One of those struts broke free during flight," Musk told reporters on a conference call to discuss the June 28 blast on what was supposed to be a routine cargo mission to the International Space Station.
  • Thijs Versloot on 21 Jul 15
     
    I guess this is how it starts as they mentioned they will inspect struts individually before each flight. Also for the space shuttle they believed a rapid inspection between launches would be feasible, but in the end there was a need for individual assessment almost. And we haven't even considered human spaceflight yet.

    as predicted, first failure, first inquiry board, first new safety procedures ... and certainly many more will follow and all will make sense but with the risk of loosing the competitive edge

    reading the qz article, it is not clear to me that google dropped out as one of the main investors in SpaceX? did I miss something?

    I attended a presentation by H. Hemmati, formerly at NASA's JPL, now at Facebook working to "connect the unconnected" during a panel session of the Workshop "Shining light on future space optical communications". I gather that they are targeting a combined strategy of HAP (with solar powered planes at 20-25 km), balloons and satellites. The rationale behind is that each solution is best suited for different population density zones, i.e. satellites while expensive (total cost of 100MUSD after Hemmati) are the only way to provide internet in remote zones, while balloons seem to be one inexpensive solution for densely populated areas. Funfact: he mentioned that the main drawback will be some crashes of HAP elements...

    Facebook announced they are ready to test of of their High Altitude Platform element, a drone of the size of a Boeing 737. See the new here http://phys.org/news/2015-07-facebook-ready-giant-drone-internet.html?utm_source=nwletter&utm_medium=email&utm_content=ctgr-item&utm_campaign=daily-nwletter. It seemed interesting for me that they are developing also a reliable optical communication between this element and scattered ground stations.

    Nice link, that thing is huge and I would love to see a drone that size fly. Also, Facebook's Aerospace Team? :)

  • NASA has 50 years of experience with reentry capsules, but is fearful of trying something new. SpaceX has no reentry experience and chooses the most efficient engineering approach. Guess whose capsule is overweight and still sitting on the ground? Guess whose capsule completed a successful first flight yesterday?

    very nice success by what we called in 2003 "the second space age" ... for Joris: (related to the discussion we had the other day) But the spacecraft will be assembled, integrated and tested in the United States and will include U.S. hardware, meaning they would not be allowed for launch aboard Indian or Chinese rockets under current U.S. regulations.

  • 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.

    Nice one, very impressive (also filming it with a drone :)! I noticed at 0:56 that the exhaust flames do travel upwards on the descent. I wonder how much of a problem this would be for the actual reusability / next flight approval?
