We have considered and dropped several launch dates over the summer as we've made progress. As you may have heard our last potential launch date was this weekend. However we've determined the weather is unacceptable for a launch and will only get worse over the winter. Sadly we are forgoing a launch this year. Despite this we have made great progress on our system. Stay tuned for a guaranteed launch when the weather turns nice this spring! As always our public meetings are Tuesdays at 7:00 pm in FAB 86-01 at Portland State University. Over the winter we will be putting the final touches on our world class rocket avionics system.

We arrived Saturday and worked on setting up launch control and the launch tower and camp. We spent the night putting the finishing touches on the flight computer. Sunday afternoon we made our way through checklists and after working a few issues we were ready to launch. We cleared the pad and sent the launch command to the tower. The igniter fired but just as the motor lit there was a bang and the rocket lifted about 30 feet off the ground and fell back to Earth. After waiting for the launch area to be clear we went to the rocket and discovered that the aft closure had failed and all the fuel grains fell out the bottom of the rocket. We suspect that one or more of the fuel grains were defective and ignited so fast that the pressure in the motor casing caused it to fail. Luckily there was fairly minor damage to the rocket body. The flight electronics appear to be unharmed. On Tuesday we will work on</pre> Nathan Bergey 2011-08-01T19:13:16 http://permalink.gmane.org/gmane.science.aerospace.psas.announce/7 <pre>The Portland State Aerospace Society (http://psas.pdx.edu/) is pleased to announce that we are on target for a Sunday July 31st launch of our rocket, 'Launch Vehicle No. 2.3', outside of Brothers, Oregon. This will be the fourth launch on this airframe, flying on an CTI N2850 motor. This should propel our 12 foot high, 70 pound aluminum and fiberglass rocket to an altitude of over 15,000 feet! This time we are testing a new flight computer and new antennas. We will also be flying the same roll control module from the last flight (see: http://psas.pdx.edu/news/2010-10-17-2/ ). We'll be departing Portland Saturday July 30th for Brothers (which is about 40 miles east of Bend, Oregon) and setting up in the late afternoon. We plan to launch on Sunday between noon and 2:00pm, which should allow some to make a day trip out of the launch, although it is more than four hours one way from Portland to Brothers.
