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."
There's got to be a beacon incorporated into the design because if that thing (30 cm.) lands in a very deep spot in the ocean it's going to be hard to find!
What good is a lost blackbox?Besides, they are planning on attaching these to unmanned craft first. This will give them a great deal of information about how the materials used react to reentry. This helps make things safer for people on the ground as they really can design craft that disintegrate on reentry.
Where's the Kaboom?
There's supposed to be an Earth-shattering Kaboom.
My Honda Civic has a black box to record crash data, but $100 million space craft don't. Um, duh.
Maybe because the entire craft is subject to different performance requirements than the black box alone? You know, like low weight? And note that the survivability of the black box results from the survivability of the entire craft that houses the box. The black box only remains after most of the reentry energy has been used to burn up the rest of the craft.
