The minimum design lifetime isn't the actual lifetime of the mission. I believe there is enough helium for three years, but the multistage cooler is designed to be able to run in the event of coolant loss. ASTRO-H replaces ASTRO-E2 which suffered a catastrophic coolant loss. There are more details here, but it's behind a paywall.

p>No CAT Scan, MRI or Cancer drugs would have been invented without patents to give the inventors time to make their years of investment back by a period of exclusivity.

Really? Most fundamental medical advances are created in academia, mostly with public money. Many companies just take the relatively small step to a commercial product. William H. Oldendorf would have done his pioneering work on the CAT scan, whether there was a patent system or not. Indeed, looking at his wikipedia biography, he worked in public institutions for most of his life.

It has been one of the wettest ever Junes here in the UK and it is still raining heavily. When it is not raining it's heavy cloud. Although that's stereotypical weather here, it's more like what you'd expect in the winter. I'm feeling like an extra in Waterworld and shall shortly be growing gills... The problems started when drought measures were brought in to combat falling water reserves.

the effect of radio frequency exposure upon living tissue (approximatly none) is well-studied and understood.

Oh really? I trust that you will now go home and put your head in a microwave oven for a few minutes. Of course some radio waves are harmless and some are harmful, it's just a question of where the boundary lies. Given that you're unlikely to have a smart meter sitting next to you all day, it's pretty unlikely to be harmful.

The dark matter in the universe started with a random fluctuation field - see the pictures of the cosmic background radiation. The random distribution gives a tidal torque on matter, giving it angular momentum. As the dark matter collapses into smaller and smaller regions, the angular momentum is conserved. When smaller sub-units of matter collide together the momentum will also build up. See Peebles 1969 for one of the first papers.

Facebook is guilty as well - I have a choice of 4 questions - name of 1st grade teacher - can't remember - city or town mother was born in - too obvious - last 5 characters of driver's license - okay question probably - street you lived on when you were 8 - not appropriate for me. Why can't I choose something better than this?
