Comments Down

Wednesday, July 28th, 2010

The comment system has been down for two days now. I’m still chasing why.

This is what I’ve tried so far:

Reloading a new version of comments.php

resetting permalinks to default setting

Swapped themes

Upgraded wordpress

Verified <? php comments template();?> in single.php

Turning off all the pluggins

Disabled comments page breaks

Disabled threaded comments

Verified that the wordpress address (URL) is correct

Resetting the plugins folder

Up loaded new wp-admin and wp-include folders from a fresh download of wordpress

Increased available memory

I think I’ve stumped the wordpress forum.

Any ideas out there?

Cloud Chamber Test

Wednesday, July 28th, 2010

We conducted the first tests of a cloud chamber we’re flying next year. We got lots of good results however the chamber wall ended up fracturing pretty bad. Next, cloud chambers with thermal strain relief walls.

I realize that cloud chambers are rather old school. Most of this type of work is done with solid state systems. However, cloud chambers can be used to differentiate particle types while keep the weight and cost low. All three are important to get the data we need.

We put the Sky Pup up on the trailer for fitting.

Everything fit as it should. Now it needs the over the wing webbing mounts and the tail dolly tie down points.

I’ve been moving old JPA video from tape to DVD. Here a clip from a balloon launched rocket test in 1995.

The Next Tandem

Monday, July 19th, 2010

We’re getting ready for the flight of the Tandem airship this fall, but we’ve already started design work on the next Tandem.  Here’s a peek at what we’re thinking.

We intend to use Tandems for Dark Sky Station Assembly, Mach Glider launching and for launching large rockets.
