Installation of the Herschel Sunshield onto Payload Module

Currently at the European Space Research And Technology Centre (ESTEC),
Noordwijk, The Netherlands, the assembly of the Herschel Structural and Thermal
Qualification model satellite is nearing completion with its two main modules,
the payload module and the service module, already mated together.

--------------------
"After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance.
I see that such intercourse long continued would make one thoroughly prosaic, hard,
and coarse. But the longest intercourse with Nature, though in her rudest moods, does
not thus harden and make coarse. A hard, sensible man whom we liken to a rock is
indeed much harder than a rock. From hard, coarse, insensible men with whom I have
no sympathy, I go to commune with the rocks, whose hearts are comparatively soft."

- Henry David Thoreau, November 15, 1853

Oh, yes; a dual launch has been the plan for a long time to save money.

New developments with Herschel. It really is a Large Space Simulator.

http://sci.esa.int/science-e/www/object/in...fobjectid=40558

"The Herschel cryostat was moved into the Large Space Simulator at ESTEC on Sunday, 21 January, in preparation for a three week test during which the cryostat will be exposed to vacuum and temperature conditions approaching those that it will be exposed to once Herschel is launched."

Quite the scoop, Rui; congrats! smile.gif Looking forward to the periodic reports.

This is the first dedicated infrared telescope above the atmosphere that is actually a large telescope. The others' sole claim to fame was their location. For example, Spitzer has an aperture of 0.85 and ISO had an aperture of .6 meters. It should be a very exciting mission.

Thank you for that terrific complement. I actually would equate UMSF with the first sorties by semi-legged fish onto land, or the first times our distant ancestors left some warm valley in East Africa to see what was beyond the horizon.

It's that important; don't know if we can ever build a monument grand enough to commemorate it. The best testament is to keep on doing it.

Both will operate from the Lagrange L2 point ... It's going to be busy at L2 wink.gif

I believe there's isn't any competition for Herschel, some years ago there was a proposal for an 8 meter Single Aperture Far InfraRed space telescope. But did Japan not plan a large 3.5 meter Space Infrared telescope for Cosmology and Astrophysics (SPICA) ?

SPICA is under development and is on track for a 2010 launch.

I read a few weeks ago the Japanese mission got delayed, there is a chance JAXA may have a critical design flaw running through all their telescopes as Suzaku and Akari all lost a good percentage of their coolant, boiling it off into space. JAXA is now looking at funding more R&D for increasing the performance of its mechanical coolers, lack of funding may require help from NASA or ESA and the latest launch date is pushing it closer to the year 2015 (by this year JWST should have already launched). Currently the J-Government and Japanese space agency is less concerned about telescopes and more concerned about getting a sample return from the Moon to prevent them from being politically eclipsed by China.
