1. With all of the "smart people" at MIT it looks like they could have figured out how to put PIP with this video so we could see the slides she is showing to the students. For MIT PIP is an acronym for picture in picture. Here's a better easier solution. Instead of keeping a close frame on the speakers upper body pull out the zoom so we could see the projection screen.
2. EXTRA NOTATION ON SPACE-FRAME PRESSURE AERO-FRAME REPAIRS BASED IN EVOLUTION OF PRODUCTS:The nature of Earth to near space orbital package payloads deliveries, because of budget constraints having those companies stay alive financially, may be based in auto-self delivery to orbit systems, or modified versions of advanced space planes.
   
   For an example, but only as a product in demonstration, in the EU there is an automated version of a space plane being developed now.However this product only in the prototype stage is directed from ground based stations along with guidance from take-off to orbit, via robotic self software.
   
   If for some reason there is either damage or impact with some foreign object in space, and that return payload is deemed exceedingly valuable, this repair job may enter a new real of thermal protection and technology.
   
   On the newer proposed space planes, they may utilize both an improve materials composition of the materials that makes up the exterior skin of the TPL. This media factor may involve a capillary flow design of cooling or heating, to where either a gas or liquid flows through tiny tubes, just below the exterior skin of this aircraft.
   
   Damage to such a construction via EVA to get at the problem might entail, a new type of ready to install patch, that only requires that the exterior surface is wiped with a cloth, to absorb this coolant, then a special self curing patch applied to the outer skin of this vehicle.*It may be possible that the cooling of heating liquid could be rerouted, till the repair is made?
   
   Links for the physics of bird strikes, to begin with.Please search for more info. via your endeavors, **Keep in mind that this would be an interior pumped temperature change to the from inner to outer regime of the space ship/plane inner-space, so knowing what your panel read or telemetried real-time data would be, so repairs could be effected, is of paramount importants?

3. INPUT Notes from student:They could have issued a rapid response team via an older ship with an emergency module plug with supplies, if an outer air-frame hull check had ascertained that exterior TPL thermal protection layer, was either damaged or not 100% up to par.This option would have to insert as to pre-established pre-launched mission orbital trajectory natures to route.
   
   This could have been a re-designed Mercury or Gemini size grade of capsule, with a take along service plug, launched atop an Atlas or Titan earlier vintage booster.This could have been either a crew trained for exterior repairs to TPL knowledge and requirements, or just the supplied remotely directed to par shuttle orbital routes.
   
   What is known and understood about shuttle TPL, is that there are layers established, so the space walkers on EVA commands would must cleans out damaged portions of loose tile TPL remnants,.2.Then ascertain condition of layer and substrata coupled with under structural aluminum and felt mat mounting layer.
   
   3.If examination along with survey looks good and a zero G and vacuum repair to reestablished TPL restored to as near original condition is a go, then this action for in-orbit repair is taken.*Note that this repair is NOT factory supervised and qualified, so as best an effort to repair to desired action, must then be deemed as an acceptable repair, or not?
   
   4.For EVA post Ingres back into either visiting rescue or into shuttle orbiter, all adhesive glue mixtures must be localized and cleaned off of EVA suites, is curing fumes are a problem.@.That ground tracking must match known orbital path matched to any proposed rescue spacecraft manned or otherwise, so that flight paths are near rendezvous per-planning intention..__Note this method of repair in now obsolete, as the shuttle orbiter has been termed by the space agency, at least overtly by news sources, to be a retired vehicle.. Best attempt, if you have comments or criticisms here, then please voice them.Thank you
   
   Missed notes.New types of spacecraft, if any exterior damage is noticed to air-frame pressure hull, that a possible same natured scenario could be constructed, say for a newer industry craft, real or proposed and additionally applicable to other forms of updated space planes.
4. Well we did have a Hubble mission and that awesome. The space shuttle is dead now and I think its a good thing. Focussing on other thing is what in the news now, not the next space shuttle flight.
5. Would have been nice to see the videos being shown to the class.
6. these group studies are good for people. Get the info out. Keeping secrets from everyone is no good. You should learn from yours or others mistakes. 
7. Idiots at MIT?! You are wrong dude.
8. Hey, Sally Ride is Martian Klan and they have no Gender so even after Sally Ride or whatever her real name is__there still were no real human women astronuts! I wonder if these Idiots at MIT dared to investigate the design of the Space Shuttle propulsion system. Notice the design flaw fellas? The SRBs made most of the thrust so why bolt on that old Von Braun junk and the LOX-H Bomb? 14% of the thrust at a cost of all that gear and the LOX-H Bomb Tank? Thank you Sadoway! They designed a bomb!
9. good 
10. @gsandeepaero Exactly. The lady is interesting and all but not really the discussion subject :)
11. I will be more interested if I can see the power point....
