MTA launch event, 2017-03-25

Posted on by

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!

USC sets new altitude record with Fathom II

Posted on by

The University of Southern California Rocket Propulsion Laboratory (USC RPL) has posted the results from their recent launch of their Fathom II vehicle from Spaceport America in New Mexico.

The link below goes into greater detail:
USC RPL breaks altitude record with Fathom II

The Fathom II vehicle was confirmed to have reached an altitude of 144,000 feet (43.98 km) on March 4, 2017. USC RPL now is the record holder for the highest altitude achieved by a wholly student built and launched rocket.

USC RPL has been working hard over the years to reach this plateau of success. USC has conducted many tests and even launched some of their early vehicles from the RRS Mojave Test Area.

Next stop will be USC building and launching their larger full-scale SpaceShot vehicle to cross the von Karman line of 100 km altitude (328,083 feet 3 inches).

The RRS congratulates USC on this stellar accomplishment and we hope to hear all about it at the RRS symposium at USC’s presentation in our speaker series, Saturday, April 22nd.

The symposium is open to the public at the Ken Nakaoka Community Center in Gardena, CA. Well done, USC!

March 2017 meeting

Posted on by

We started the March 10th monthly meeting a bit late, 7:51pm. As usual, we met in Gardena at the Ken Nakaoka Community Center.

The first item was to discuss the progress of the upcoming RRS symposium to be held Saturday, April 22nd. We have confirmed several speakers and exhibitors including UCLA, USC, Caltech, CSULB, Cal Poly Pomona, Orbital-ATK, Norton Sales, Spaceport America, Mars City Design and the Aerospace Corporation. We still have a few speakers yet to confirm, but we will have a full listing which will be great for our public audience. We encourage everyone to download and share this flyer with everyone who would like to come out to the Ken Nakaoka Community Center in Gardena.

Osvaldo surprised us all by completing the full-scale mockup of the SuperDosa boosted dart vehicle. The SuperDosa project is the RRS’s recent project to retake the amateur rocketry altitude record and rebuild many of our old capabilities from 20 years ago when the RRS held the record. This will be on display along with RRS standard alpha and beta rockets at the exhibitor hall during the symposium on April 22nd.

Although we’ve been having weekly teleconferences, the meeting offered the opportunity to discuss issues and address questions by all of those in attendance. Dr. Chris Zeineh of the Aerospace Corporation and four students from UCLA’s liquid bi-prop rocket team were in attendance. Frank had printed a few flyers and some of the brochures we plan to have at the symposium.

Our public relations campaign to advertise the RRS symposium is in full gear as we’re trying to get radio and TV spots in the local media market.

Frank also made an Eventbrite posting for the RRS symposium. It’s a free event so there’s no cost to register. Registering allows the RRS to gauge how big our audience might be. We’ll try to have food available at this event. I encourage everyone to register for the symposiuim at this event at the link below.

John Mariano is working with his contacts at JPL to try to see if we can have the Explorer 1 satellite mockup on display as a really neat piece of space exploration history as this was the United States’ first satellite launched over 50 years ago. We hope we can bring that piece of history to the exhibition.

The RRS has updated our Facebook page to get the word out. The link is below. Our members who are on Facebook should join this group. Anyone else is also welcome to join our Facebook page.

RRS Facebook page

The RRS will create an Instagram account soon which may make viewing our launch event photos and videos much easier. I plan to do this sometime before the next meeting in April.

The weekly teleconferences will continue in the ensuing weeks as we are less than 6 weeks out from the event, but looking to be in good shape. We hope to confirm more speakers and exhibitors very soon.

In other non-symposium related news, the RRS history project is progressing. I made contact with the Caltech Library to acquire electronic copies of three Astro-Jet newsletters from 1945 and 1946 which is when the RRS was known as the “Glendale Rocket Society”. We hope to get these and any other Astro-Jet newsletters added to our library archives soon.

Also, Richard Garcia acquired a nice Marotta solenoid valve from Norton Sales which could come in handy for future projects. The RRS still has plans to build a liquid propellant testing rig in the future.

I am also steadily working on making a simple thrust stand for firing alpha and beta rockets in the near future using the load cell kindly provided by our friends at Interface Force in Arizona.

We have rescheduled the March 18th launch event to a week later, March 25th. The girls academic leadership academy (GALA) will be launching four alphas. Larry and I may have another alpha or a beta for this event. We have invited UCLA to attend the launch to show them the Mojave Test Area (MTA) in advance of the two events they will be having with us.

UCLA has confirmed that they would like to conduct a hot-fire test series at the MTA for their IREC rocket systems on April 29th. There will be hybrid and solid motors tests. We also hope to have a few other people conduct launches or hot-firings.

Also, on June 3rd, UCLA will have a launch event at the RRS MTA to conclude the undergraduate class featuring two RRS standard alphas and two RRS standard betas and a set of ten smaller model rockets.

Lastly, USC had a very successful launch of their Fathom II rocket at Spaceport America last week. I invited USC to come and share in their results, but they are still compiling a posting for their website (link below). Also, this Friday they were properly celebrating their success. We hope to read their results soon. Also they have posted photos on their Instagram feed.

Our next meeting will be Friday, April 14th. This will be the last one before the symposium (April 22nd). I encourage all of our presenters and exhibitors to come out for this meeting to give you the opportunity to review the space and ask any last minute questions beforehand. Frank Miuccio and I are available anytime to answer questions by phone or email, but sometimes it’s best to walk the space in person.

Let me know if I missed anything or if anything posted here needs correction.
