No pressure then...

Now some of you out there know pressure when they experience it, but shed a thought for the NASA engineers fixing the Hubble Space Telescope. There has been a malfunction in the Science Data Formatter which is responsible for downloading data to Earth based stations, NASA want to switch over to the redundant unit which hasn't been used since pre-launch. Now if this doesn't go according to plan, then potentially the HST is useless. Add to that pressure because Atlantis is posed for launching to service the HST, albeit not this component therefore if it doesn't work that mission could be scrubbed. Then add to that more pressure as Atlantis is not able to get to the ISS in case of emergency, then Endeavour is also ready to launch as a rescue vehicle.

I can just imagine some poor engineers sweating profusely totally engulfed in computer printouts trying to fix the problem.

Well that puts my day job into perspective. I don't think I will complain about being under pressure again.
