Thanks for sharing - looks like a needed upgrade! (Re: New satellite launched)

Dear Blick and WeatherCat weather tech observers,

First of it's kind, with three more to follow, weather satellite launched this morning.

Thanks for sharing.  I didn't know that NASA was upgrading the polar orbiting satellites as well as the geosynchronous weather satellites.  Looks like the upgrade was needed.  I do hope the other 3 satellites will in orbit soon as well as the geosynchronous satellite for the west coast.

Cheers, Edouard

I think it's NOAA that is upgrading the satellites, NASA just provides the rides. ;) As mentioned, there is only one more Atlas available. I assume that means of the originals. ULA has re-built some using Russian (RD-180 rocket motors). At any rate, disposable/expendable rockets are wasting lots of money on one shot 'tricks'. OTOH, this is another method of incentivizing miniaturization! ;) And, of course, commercialization of re-usable vehicles. ThU5:-)

Some space trivia (Re: New weather satellite launched)

Dear X-Air and WeatherCat seekers of space-based trivia . . . .

I think it's NOAA that is upgrading the satellites, NASA just provides the rides. ;)

It isn't like it really matters but supposedly the satellites are operated in a "partnership" between NOAA and NASA.  I do hope government agencies can get along in situations like this, but one can never be too sure.

As mentioned, there is only one more Atlas available. I assume that means of the originals.

Again mostly trivial pursuits, but the launch vehicle in this case was actually a Delta II.  It is a venerable design that dates all the back to about 1960!

 
ULA has re-built some using Russian (RD-180 rocket motors).

This is where there is a point worth pursuing perhaps.  The story behind the Russian RD-180 rocket motor is fascinating and if you have Netflix streaming there is a neat documentary on the development of that motor:

Anyone interested in the space program and how rocket engines works will really enjoy it.

Cheers, Edouard
