| Certainly helps with their next set of grant proposals.

| Live cam data can be useful in analysis of failures.

| Probably doesn't matter much for this one as it is the last

| What can a camera tell you that more sensors couldn't?

| A camera _is_ a sensor.
| Kye wrote:
| A camera is a tool for rendering light on a medium. That
| medium could be a sensor. Rendered light can tell you a
| lot about what the medium is facing, but you can pack a
| lot more sensors than cameras on to a spacecraft.
| Especially on the parts that aren't illuminated. Besides,
| you need a big sensor on a camera to capture anything in
| low light without a lot of expensive processing, and that
| means you need shielding and cooling because they get hot
| and don't do well in all that radiation.
|
| So sure. You _could_ put huge chips in hot boxes with
| delicate glass all over the craft. Or could you wire in a
| bundle of little sensors that tell you stuff you 'd never
| get from light.

| An early Falcon 1 launch failed because the first stage

| the F9 cameras is looking up at the second stage from
| inside the first stage's interstage section.

| The Columbia case is a better example than the Challenger
| case, because they actually caught that right after
| launch and analyzed it, though incorrectly.
| ncphil wrote:
| Well, the analysis at the engineering level was correct.
| Problem is, the engineers weren't allowed to confirm it.
| That was a management decision, made on the grounds that,
| "There's nothing we can do".
| macintux wrote:

|
| And I assume a sensor can tell you "this piece stopped
| talking" but a camera in right place could tell you
| "because it fell off when a screw fell out", so presumably
| they're complementary.

| A similar argument could be made for a key being

|
| It's a great read. It's thoroughly and wonderfully human.
