back to article ISS ammonia pump 'working well'

The ISS's new ammonia pump module is "working well", according to NASA, as the agency prepares to return the orbiting outpost to "normal configuration for standard operations by Thursday". It took spacewalkers Tracy Caldwell Dyson and Doug Wheelock three EVAs to swap out the failed unit, which died on 31 July and knocked out …

    EDT/CDT Just use Zulu!

    In Air Traffic Control, everyone around the world refers to 'Zulu time' (UTC), which helpfully enough is just GMT. Absolutely no idea why NASA don't do this as pretty much all other aerospace industry does and has done for years. From wikipedia:

    "UTC is the time system used for many Internet and World Wide Web standards. In particular, the Network Time Protocol, which is designed to synchronise the clocks of many computers over the Internet (usually to that of a known accurate atomic clock), uses UTC.

    Those who transmit on the amateur radio bands often log the time of their radio contacts in UTC, as transmissions can go worldwide on some frequencies.

    UTC is also the time system used in aviation, Weather forecastings, flight plans, air traffic control clearances, and maps all use UTC (also colloquially referred to as "Zulu Time") to avoid confusion about time zones and daylight saving time."

      UTC not GMT?

      I thought that there was typically a non-zero difference (in seconds) between GMT (average solar time at Grenwich) and UTC (adjusted atomic clock measurement)?

      NASA should really use it whatever it's called though.

    NASA Timezones

    It's because the typical American is too stupid to be able to convert from GMT.

    The EDT/CDT thing is because NASA PAO is too stupid to remember if the particular event is in Houston time or KSC time. They do it all the time on NASA TV and yes, it's extremely irritating.
