It's About Time!


Recommended Posts

A dignified launch for such a powerful team: NASA in conjunction with the European Space Agency (ESA) and the Canadian Space Agency (CSA).

We should be ready to reconsider our visions, according to the unbelievable increase of the universe's grasp as for the distances and new evidence.

And speculations for the new Earth :)

The October issue of Astronomy Magazine, which arrived in the post a few days ago, has an excellent article on the James Webb Space telescope. The article was written by John Mather, who is the senior project scientist for James Webb, and who won the Nobel Prize for work that first observed the variations in the Cosmic Microwave Background (CMB).

The precision and wisdom of NASA scientists and engineers must make it successful. The Webb Telescope ran through the launch and operating scenarios, which took into account it’s complexity, weight, possibilities of maintenance, and one of the most important - the fuel amount. Still it is necessary to work within the laws of physics.

And I believe, all the tests considered scenarios from a ‘perfect launch’ to the worst case - which will still put the telescope to orbit.

Making more than one might have a lot of time as another main  resource to be consumed.

I just hope they have a backup, its often just as cheap to make more than one..

I recall the US military had several spare Hubble size mirrors (different focal ratio) from their spy satellite program two of which they gave to NASA some years later.
