Well, then we're not going anywhere. NASA cannot *afford* a Saturn V class vehicle with its current budget. That budget is not going to increase any time soon. Therefore, we have to get the best for our money. That means Shuttle-C or DIRECT. Ares 5 is just too big for the infrastructure we have.

Laser projector? How can you project a raster image using a inherently vector system?

I don't get it. How does it know how big the pixels should be?

(Or maybe it's obvious and I just need a beating with the clue stick here)

The light from the three RGB lasers is scanned in rows just like the electron beam in a CRT. To sweep the angle, a tiny mirror flexes very fast. The technical challenge for these projectors has been switching the mirror fast enough and getting decent performance from miniature red green and blue lasers. I think the blue one was the tough nut to crack.

Comment This is an old, old blacklist (Score 5, Insightful) 122

This blacklist was specifically for the construction industry - for those who haven't RTFA. The terrible thing is that this list, and its sale for money, has been around for years and years. It's the industry's dirty little secret. It's only now they've computerised the records that they can use the Data Protection Act to prosecute. Sadly, I have no doubt that the information will live on somehow. All the major players have fingers in the pie and won't give it up, I think.
