Black Boxes for Spacecrafts

karvind writes "NewScientist is running story about NASA's plan to put small, heat-resistant black boxes that will transmit data back to Earth when future space probes break up during re-entry to the Earth's atmosphere. NASA will work with Aerospace Corporation to develop black boxes called Reentry Breakup Recorders (REBRs) weighing just 1 kilogram and spanning less than 30 centimetres."

      I'm not sure how serious you meant this comment to be, but here goes:

      The first problem is that electronics can be designed to survive much greater accelerations than can the human body. Remember: Only the small pieces of silicon containing the data need survive the impact for the data to be recoved, but a brief 65g-75g acceleration will scramble one's brain.

      The second problem is that, even if you assume that your "black box" design can reduce the accleration of its contents to something survivable, you still have to find a way to make a large-enough black-box to contain the crew without the black-box being too heavy or too big to be launched into space.

      It's called a 'capsule'. They built a bunch of them in the 60's, worked quite well. There were a few minor system failures on the capsules, example, a hatch blew on one, causing it to sink after impact. As a whole, the capsules performed this task quite well overall, there were no fatalities attributed to riding a capsule thru re-entry. The only fatal failure mode occurred when it was pressurized with pure o2, well beyond the design limits of the unit for pressurization, and then they put some sparks into the mix. Net result, a fire.

      It's interesting to note, that the capsules in that era were basically failsafe devices. As long as they hit the atmosphere within the correct range of contact angles, just sit back and enjoy the ride, the aerodynamics of the unit kept it on a surviveable trajectory. Parachutes were a nice touch to reduce final impact loads, but as long as astronauts were properly seated in thier accelleration couches, the impact without parachutes would be surviveable (albeit, some astronaut damage was likely).

      Nasa has had 50 years of technology advances to improve on this design. The 'improvements' have no end of failure modes, and somewhere along the line, they discarded the concepts of failsafe. Ahh, the joys of mixing 50 years of beaurocracy into the pie.

      A parachute failure in any of the manned capsules would have likely been fatal.

      In all, four astronauts have died in capsules during or after rentry, but none because of the reentry itself. Komarov crashed without a parachute, the crew of Soyuz-11 died when a pressure release valve that was desinged to provide fresh air to the crew after reentry was accidently opened early. The crew suffocated.

      You are confusing a soyuz landing on terra-firma with an apollo capsule splashing into the ocean. The impact with the ground is abrupt, resulting in a shock load of many thousands of g's, for a very very short period of time. The water impact will be hard, but, it will spread the energy dissipation over a short period of time as the capsule submerges. There is a world of difference between the forces involved in the hard landing where energy is dissipated virtually instantaneously, vs those involved in a water landing where the energy is dissipated over a measureable period of time.

      Terminal velocity of the capsule would run in the 240mph range. Take a look at the race track for real world examples. Head on to the concrete wall is not surviveable in most cases. In accidents where the deceleration is spread out over 100 feet or so, drivers wearing the appropriate restraining gear for head/neck tend to survive. Those not wearing it, tend to die. Capsule astronauts actually have an advantage over race drivers, they are seated back to the impact, in an accelleration couch molded to fit thier body, with solid head/neck support. The water impact is equivalent to a modern race car going into modern track barriers designed to absorb energy. The ground impact is equivalent to modern race cars going into the concrete wall, head on, full speed. Amazingly, drivers tend to walk away from the former, but rarely the latter.

      This ofc pre-supposes the capsule itself survived the impact. Not really a big assumption, it was a design criteria for those capsules. The water landing without parachutes would have resulted in badly bruised astronauts, probably some broken bones, but they had a very good chance of survival. There were many reasons for choosing ocean landings for those programs, even tho it was many orders of magnitude more expensive to mount recovery operations. This was one of the biggies in that decision tree.

    Well, the key to "black boxes" is not solely the box.
    Of course the box should be built to remain intact after e.g. falling through the athmosphere without external heatshielding, then impacting on the ocean with Mach-2. But the components inside must be built robust enough to survice an Mach-2 impact as well. And I don't think today's astronauts can really take that...
