Presidio, Texas, Rocketry Teacher Gets Green Card

Two years ago, Shella Condino, a Texas teacher known for using rocketry to inspire and educate, received a letter from the US Immigrations Service saying, “You are not authorized to remain in the United States and to depart as soon as possible.”

A Texas congressman investigated and learned that the letter had been sent by mistake. Shella Condino now has a “Green Card” and continues to inspire her students in Presidio, Texas. Earlier this year, she once again, lead a team of kids to the Team America Rocketry Challenge finals. The team finished fourth over all in the nationwide competition.

Free Android App Measures Diameters

A new Android app which measures diameters may be useful to rocketry hobbyists. ON Diameter is a free app which measures the diameter of an object such as a model rocket body tube.

You place the object to be measured anywhere on your Android device’s screen then move three cross points to align with the object’s boundary. The object’s diameter and area will be shown on the screen. You can toggle the units to select inches or millimeters.

The screen shots above show the app being used to measure several items as well as the screens used to calibrate your device for accurate measurements.

The ON Diameter app is available from the Google Play store.

RCS, Inc. (Aerotech) and Quest Aerospace, Inc. Announce Merger

RCS Information Release

July 18, 2013 RCS, Inc. and Quest Aerospace, Inc. Announce Merger

RCS Rocket Motor Components (RCS), Inc. President Gary C. Rosenfield announced today that the two companies have successfully completed a corporate merger.

The Coolest Hobby Rocket of All Time

I just posted a blog entry at PayloadBay.com about the University High School Space Shuttle. The space shuttle model stood about five-foot tall and flew on an I motor. Unlike every other flying space shuttle model, it did not have any added fins for stability. At apogee, the Solid Rocket Boosters separated and the orbiter began gliding back to earth under radio control. The rocket flew several times including a flight at Epcot.

Could it be the coolest hobby rocket that ever flew? Maybe.

Another contender would have to be Steve Eve’s Saturn V. Steve’s 1/10 scale Saturn V stood about 40 feet tall. It flew on a cluster of motors producing more than 40,000 pounds of thrust. It’s one, and only, flight attracted a crowd numbering about 5000. Based on the number of videos posted online, it was probably to most photographed hobby rocket launch of all time.

Then there’s the CSXT

Testing the Estes Pro Series II Igniters

There have been many online reports of people having problems using Estes’s new Pro Series II igniters to light composite motors such as the new motors from Estes. Some people have even reported a 100% failure rate using the new igniters.

Others, however, have found that the new igniters work well in Estes and Aerotech composite motors. Michael Fritz, Marketing Director at Estes-Cox, responded to the reports of failure by posting:

…as I’ve stated elsewhere, we tested a huge number (thousands – all off of our E Launcher) of these before releasing them to the public…and considering our production history with our standard igniters, we have a pretty good handle on how to make them and make them work. I know this will sound very CYA, but we have been using them with the PSII composite motors here at the rocket ranch, launched off our E Pad (and new PSII pad) with the

A Look Inside a Composite Rocket Motor

I don’t normally re-post things found in other rocketry blogs, but the video posted recently in R2K’s High Power Rocketry Blog is just too cool not to share. The video is an animation which illustrates the assembly and function of a typical APCP composite propellant rocket motor as used in many hobby rockets.
