Syfy's Ascension has a nuclear pulse starship

That's enough for me to set the DVR. Ascension is a three night event, which according to Syfy's website, will start December 15th at 9/8c (even though the video says November 24th).

Scott Lowther has posted his preview of the show, based on several short videos that he has also embedded.  He also includes some screen snaps, focussing on the starship of course.

I'll just embed the behind-the-scenes video.

The origin of the swing wing glider design (?)

Here is a nice photo of winged rockets by German rocket pioneer Reinhold Tiling. These swing wing rockets apparently were used to carry mail. And, were good inspiration for modern swing wing modroc gliders. (via Dan Sharp's Flickr stream)

World record static model water rocket

I thought this awfully ambitious project was worth a look-see, even if it didn't fly. There are also some photos on BSA Troop 227's web page.

A brief history of Wernher Von Braun, 1950 - 1970

This '1950' image is the starting point. If you click that you will get to Dan Beaumont's (virtual) Space Museum. Navigate to the right to see the remaining images. See also the PBS "Missile to Moon" documentary.

Nice article on the state of hybrid motor technology

IEEE Spectrum has a nice article by Stanford professor Brian J. Cantwell: Wax Fuel Gives Hybrid Rockets More Oomph. Dr. Cantwell, who is also a principal at the Space Propulsion Group, is researching advanced hybrids based on paraffin and either liquid oxygen or nitrous oxide. The article is packed with interesting factoids and discusses what is now, undoubtedly, the most well known hybrid rocket, i.e. the one that has been powering the SpaceShipTwo. This article is well worth the read.
