MTA launch event, 2017-03-25

The RRS was pleased to host a launch event at our Mojave Test Area (MTA) for the Girls Academic Leadership Academy (GALA) of L.A. USD on Saturday, March 25, 2017. The event had an excellent turnout.

Longtime member Dave Crisalli was our pyro-op for the event and I was able to serve as his assistant in conducting the launch of twelve alphas and a beta rocket.

Before we got started, we had a safety briefing showing how launch will take place and what to do before, during and after firing. To give an appreciation for the propellants commonly used in amateur rocketry, at a safe distance, we burned a sample of the micrograin.

We had 12 alphas and 1 beta for launch. GALA did a great job in painting their rockets. The bright colors not only distinguished one from the other, but they also made finding them downrange by their tailfins in the desert much easier to do. GALA also was wise to number their rockets. We took good notes on the flight times of each (35-38 seconds which is typical). With the wind noise, it wasn’t always possible to hear the faint thump. GALA did well in keeping quiet after launch to hear the thump and figure the direction where it was heard.

Osvaldo equipped the last of the 12 alphas (all the way to the right in the photo below) with another fin-mounted keychain camera similar to what was done at the November 2016 launch event. Alas, it was not to be, the camera was destroyed and no footage was captured.

The beta was without payload except for the wooden adapter and a plastic Easter egg half as a nose cone. A buzzer and a strobe device was mounted to the beta fins in hopes to be better able to locate the vehicle in the search. Unfortunately, the beta, too was lost. No sound of impact was heard.

Dr. Mitchell Spearrin of UCLA came by the event to tour the MTA as the RRS looks forward to working UCLA on their upcoming projects. Dr. Spearrin brought an Estes Ascender model rocket of his own to test at the MTA with a commercial F-motor. At the end of the GALA rockets, the model rocket was launched. I didn’t get any photos. I believe the winds carried the light rocket pretty far east of the MTA site. I understand that the rocket wasn’t able to be recovered.

Several of the alpha rockets launched by GALA were able to be recovered through hard work and sweat. I think of the 12 launches, 7 were recovered? An excellent job by the GALA team in finding and recovering a lot of the hardware.

The RRS wants to thank GALA for their participation and hope they enjoyed the day as we did! We hope to have GALA come back for another event. Also, many thanks to Don Purpurra for contributing his photos of the event. The shots of the alphas and betas he took were incredible!
