NASA Clears Shuttle Atlantis for Sunday Launch
Davemania writes "This Sunday, NASA will resume the reconstruction of the International Space Station with the launch of the Space Shuttle Atlantis. NASA predicts a 60% chance that the weather will hold but will be keeping their eye at Tropical Storm Ernesto. The six-astronaut crew is tasked with deploying two large solar arrays and integrating the port 3/port 4 truss segment. As usual, the live launch can be seen on NASA TV."
Space shuttle "Antlantis" doesn't exactly fill me with confidence - I mean, why not just go with "Space Shuttle sinking continent" or "Space Shuttle doomed civilization"
There are shills on slashdot. Apparently, I'm one of them.
Good luck! As long as they keep those motherf%^#ing snakes off the shuttle, they're in good shape!
Where were you when the voynix came?
Godspeed Atlantis! (and don't forget your spatula!)

Actually, the Space Shuttle's systems are run on proprietary software written by a company that basically just writes the shuttle software. They have uber-secure programming practices to prevent any bugs in the system. The software, because it's so carefully written, is the most expensive piece of software in terms of dollars per line.

Well, you never know when you're going to get lunched into space.
Sometimes, these get togethers ...just..take...off.
And of course, the shuttle has plenty of LOX. What better way to have Sunday lunch than with salmon and cream cheese.
Yeaap. I'm done now.

Specifically, of the five CPUs in the primary Shuttle management system, four run identical copies of the management/control software. This version was originally written by IBM's then Federal Systems Division, which was later sold (to Loral I believe). The fifth CPU runs code written to the same specifictions by the shuttle's prime contractor (then Rockwell, now Boeing). The two groups were (and I believe are) only allowed to communicate through formal written specifications and are never allowed to speak directly or to see one another's code. Whenever the software is changed, both versions must independently pass the same functional tests and then the entire cluster of five CPUs must pass the functional tests as a unit.
I haven't seen any detailed write-ups since they upgraded the Shuttle cockpit using what was essentially the Boeing 767 avionics, but I assume similar procedures still apply.

Indiana Jones found it. So it must be real.

Try doing it without air, and hundreds of kilometers above ground, then you'll get your news appearance.
Saskboy's blog is good. 9 out of 10 dentists agree.
...but more of a realist: what percentages of shuttles have gotten-off on-time-first-time-no-probs, have been delayed for technical reasons, have been delayed for weather, and whatever-else?

'NSA clears Shuttle Atlantis for Sunday Launch'? Blah, I need more coffee.
It now says the chances of tomorrow's planned shuttle launch being scrapped are going up because of storms expected to hit central Florida.
Shuttle weather officer Kathy Winters says there's a 60 percent chance bad weather will force a scrub, up 20 percent from yesterday.
Winters says they're still hoping the sea breeze will push the storms far enough away for Atlantis to take off at 4:30 p-m, Eastern.
She says the weather looks better Monday and Tuesday, in case tomorrow is a no-go.
NASA officials are also checking to see if a lightning strike yesterday at the launch pad caused any damage.
If Hurricane Ernesto hits the gulf coast and Mission Control in Houston has to evacuate, the shuttle astronauts will spend that time just marking time. There is no backup for Mission Control in Houston.
Gods don't kill people, people with gods kill people.
How are they keeping their eye AT Ernesto?
Maybe not NASA, but certainly NOAA really can literally keep their eye AT a TS/hurricane by flying around and thru it in one of their P-3 Orions.
Atlantis is in the Pegasus Galaxy.
Please, for the good of Humanity, vote Obama.
Sorry. The shuttle DOES NOT use boineg 767 Avionics. The job of the two is VERY different. The shuttle DOES have a glass cockpit now. The eight balls like they used for attitude control on Apollo and on the old shuttle are gone.

Is it safe to launch now?

Bad timing, actually a big thunderstorm rolled through and the platform took several direct hits. Nothing hit the shuttle itself because of the series of wires and towers that they have installed to draw the lightening away, but they are still going to take the day today and tomorrow to inspect everything.

There are some ok photos of the direct hits to the tower.

"KENNEDY SPACE CENTER, Florida (CNN) -- The launch of space shuttle Atlantis on Sunday was scrubbed for 24 hours because of lightning striking the launch pad Friday and other weather worries, NASA announced.

The launch will be tried again Monday. Sunday is the first day of the shuttle's launch window, which closes September 7.
Mission managers said no other significant issues besides weather could affect the launch, said NASA test director Jeff Spaulding."

The Associated Press and the New York Times are now reporting that Atlantis will not launch Sunday. The delay will "give engineers more time to determine whether one of the most powerful lightning strikes ever at a Kennedy Space Center launch pad caused any problems. The lightning Friday didn't hit the shuttle -- it struck a wire attached to a tower used to protect the spacecraft from such strikes at the launch pad -- but it created a lightning field around the vehicle, NASA managers said. The launch, planned for Sunday, now won't happen until at least Monday."
über-secure does not mean bug free. Remember when the Shuttle fired its laser into space, instead of at a ground target, because someone calculated altitude wrong? No system is bug-free.
