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."
Why not put more effort into knowing ways not to break up? on reentry its not like we have to die. So why not put the effort into fixing things beforehand unstead of how to find out how we killed people?
Now just try finding those black boxes in the bottom of the ocean. Or when the spacecraft explodes over texas, and people take it home as a souvenir.
Shouldn't that be an "if"?
How can you avoid it if you don't know how it happens?
The Blue Screen of Orbit Reentry is not a fun thing to experience.
Why not make the entire spacecraft out of this black-box material?
There I was, walking down the street, minding my own business, when .... BONK! Black box to the head.
Toronto-area transit rider? Rate your ride.
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?Hmm, I wonder what could be inside....
is 'craft', not 'crafts' :)

Try getting back in your hive now, bitch!
If we can create boxes that survive a rough re-entry, why can't we use that technology to create entire crafts that survive such a re-entry?
Why can't we just call it a recorder?
I, for one, welcome our new black box overlords!

Those urine and feces filled "blue ice" bombs from airplanes?
I'll think I'll stay inside with my new toy instead
So... after a crash the only thing that's left is a black box?
Why don't they make the space shuttle out of the same material as the black box?

I've heard of squeezing Linux into small devices, but a window manager on a space probe is a bit ridiculous, don't you think? TCP just isn't designed to handle that much lag time and network interference.
Why didn't they just make the probe from the same material as the black box then? ;P
Especially when you do it by using the atmosphere to generate heat and bleed off all that energy.
Stop things from breaking up? How? Solid NiFe bodies (sometimes known as meteors...) break up when they enter the Earth's atmosphere at those speeds.
And "find[ing] out how we killed people" is the first step in not doing it again.
of so called "indestrubile" material...why don't they make the whole spacecraft out of this stuff?
Launching an extra kilo into orbit? That's actually pretty expensive isn't it.

Damn, my RAM is full of llamas.
If they're resistant enough to heat that they can survive the probe breaking up in the atmosphere, shouldn't we just line the probe with the same material that comprises the black boxes?

Keep that in mind.
I suggest you read Slashdot
...but I'd think desinging the spaceships so they don't break up on reentry might be a better idea.

My Honda Civic has a black box to record crash data, but $100 million space craft don't. Um, duh.
Obviously, the editorim didn't pay attentions to verb endae during their English classices.
...our new era of information saturation.
As sensors become smaller, lighter, and more networked, it makes sense to put recording devices on ANYTHING remotely mission critical, mainly because at a certain point it becomes negligent not to.
When I ride over the Queensboro Bridge in NYC, I stare up with apprehension at the thousands of rusting girders that hold that rattletrap together. The only thing forestalling a collapse is having actual dudes crawling over it all the time checking visually for cracks and obvious failures. The smart pebble technology previously mentioned on Slashdot - http://www.betterroads.com/articles/feb03b.htm - would make me feel more comfortable.
I feel the same way on airplanes- do I trust that a ground tech working for a lowest-bidder maintenance company has adequately checked the airframe? I sure would like real-time fatigue information being beamed to the pilot, so he can decide wether to fly or not based on risking his own skin.
The most amazing thing about our age of astounding engineering is still the amount of ignorance we maintain about our constructions (Bucky Fuller's famous, and unanswered question to an architect: How much does your building weigh?). Thus, safety margins, inspections, building codes, all serving as bandaids to a fundamental ignorance that bites back BIG when a failure does occurr (sure, the WTC can absorb the impact, but can it survive the potential energy bundled in a plane, including the BTUs in the fuel? Nope).
Privacy wonks will worry about networked sensors in their toilets watching them take a crap, but really, if anyone wants to see mine, they're more than welcome to it- I just don't want to hear about it (eeewwww).

An astronaut is probably more likely to die in the plane ride from Wherever, USA to Florida.
And even more likely to die from a car accident on his/her commute from the airport to the Kennedy Space Center than from a shuttle reentry.
Another thing to consider, black boxes are resistant to destruction because they are small (small surface area to be charred or impacted) and compact (little space inside the box for dislodged components to move about and further destroy themselves or other internal components.) -- Something you can't do with an entire spacecraft, it's crew, or the experiment apparati onboard.

It's about $10000/pound, so a kilo would be $4500 - just a small fraction of the cost of the black box.

Black box in space, you say?
And it took them how long to think of this?
Why don't they make the whole damn space craft out of that heat resistant material.
Really, if you can make something that will survive falling from space, shouldn't you just build that around the astronauts so that they can survive too? Hell, I'd like my car built like one as well.
porp
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...

The plural of "spacecraft" is "spacecraft".

Don't make the damn things black! There's enough dark matter out there as it is! Didn't science fiction teach these people anything? You're supposed to put colorful panels and flickering lights on it!
What's next, powering it with dark energy??
Fox can take the sky from you.
I thought, yeah, that's just what I need. A bed that comes apart in orbit and burns up on re-entry.

The name includes the "The".
The Aerospace Corporation is a federally funded research and development center (FFRDC), located in lovely El Segundo, California. El Segundo is also home to Los Angeles' Hyperion sewage processing plant, a Chevron refinery, the Los Angeles Air Force Base, and numerous other aerospace-themed venues that hearken back to the good ol' days (The Proud Bird, The Wild Goose, etc.).

But I really think that it should be called the Neon Box.
Ok the Black Box rolls off the tounge which is the leet part of lingo, but besides that.. Make it Neon or they deserve to loose it.
Taco you pathetic illiterate, the plural of "spacecraft" is "spacecraft".
Grandly entitling yourself "editor" is just wrong. You don't edit, all you do is choose from submitted stories and post them.
Haha, originally just the words 'black' and 'space', 'black' and 'box', and 'future' and 'space' stuck out at at me. (plz pick apart the grammar of that last sentence. Spacecrafts.) So I thought we were gonna put black boxes in spaceships, then fly them into black holes. That'd be awesome.
even though they do go off in bed.
I read somewhere that if you create a negative ion field around the space ship as it re-enters, it lowers the air resistance, therefore causing the ship to 'increase' in speed as it enters the atmosphere but at the same time causing less friction on the whole ship, so a purpose built 'slow-down break' could be deployed or the ion field reduced in strength to control the slow down.
Liberty freedom are no1, not dicks in suits.
If possible, have hull changing colors to represent heat or stress.
Sure the ship wont be 'white' but wierdo colors, so get off the high horse on 'visual cuteness' and make it work. There are plenty of none-electronic tricks you can do for feedbacks/status.

Bad I know... but I actually met Rick Hubbard one time at a dinner and a lecture. I ran sound at the event (400-500 people or so). He was very intelligent (tall too) and a very personablly friendly guy. I actually chatted with him for a few minutes about his time in the USAF. It is ashame of what happened; he will be missed!
is this where the aerospace union corporation originated from?
My Gawd WTF...
