NASA Ames 2015 Summer Series. NASA’s mission to push the limits of human exploration to beyond low earth orbit and to Mars will take humans farther than ever before. Achieving these goals requires collaborations and development of new technology. NASA Ames’ expertise in re-entry technology is helping develop the architecture to achieve these goals. The Orion Heat Shield is an example of the materials and technology development needed to sustain heating rates far greater than missions returning from the International Space Station. Jeremy Vander Kam describes details working with this engineering and scientific marvel.

Comments

  1. Entry velocity (7, 9, 11 does increase with more distant planets) but should be limited by the shape of the gravity well.
  2. From 2006; DDT&E work is estimated to occur from Sept. 8, 2006, through Sept. 7, 2013. The estimated value is $3.9 billion.
    RELEASE : 06-305 NASA Selects Orion Crew Exploration Vehicle Prime Contractor
    Sustaining engineering work will be assigned through task orders. The work is expected to occur from Sept. 8, 2009, through Sept. 7, 2019, with an estimated value of $750 million, if all options are exercised.
    It is now Nov 2015, design, development, testing, and evaluation (DDT&E) of the new spacecraft. DDT&E has not yet even started. Yet talk of schedule and budget is discussed with hearings in Congress. 2014; WASHINGTON — NASA has masked the true cost of the Space Launch System and Orion crew capsule by neglecting to say what these deep-space systems will cost to build and operate over the decades the agency plans to use them, according to a report from the U.S. Government Accountability Office. http://www.gao.gov/products/GAO-15-248T
  3. No one made a joke about Orion going to kill a Dragon?
  4. I wonder if the weight of the heat shield ( i think mentioned to be 4,000 pounds ) is most important for insulation/thermal dissipation or rather prioritised for being 'bottom heavy'.
  5. Thanks miss for asking about the risk in the blocks, I wanted to know 'what happens if a block falls off and how do you prevent that' which was answered.
    what was the date of recording?
  6. That was a very interesting talk! I didn't know before how ablative heat shields are made!
