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.
