We are go for launch! HARA welcomes TARC teams from around the Tennessee valley and the public to participate in low and mid power rocket flights tomorrow (March 15th) at Bragg Farms. High power rocket flights are restricted at Bragg Farms. We will target a start time of 10am, but we may start earlier or later depending on rage setup and the weather.
The address to Bragg Farms is:1180 Grimwood Rd, Toney, AL 35773
Enter Bragg Farms from Grimwood Rd on a dirt road. The road turns left then right. You will pass between barns with large harvesting equipment and their may be farming related activities in that area so please be mindful as you enter the area. Carry on down the dirt road into the field. Park off of the dirt road on the grass to the right.
You are welcome to bring coolers with snacks and drinks, and some chairs. There will not be a motor vendor, so be prepared.
Stay tuned to the website and facebook for updates on the launch. See you there!

TARC is like the real world of rocket design in that the teams must resort to design/simulation software to help flesh out the initial concept, making sure it can meet the goals before pressing on to actual construction/testing. Here the vendors have come to the rescue in providing three outstanding packages, any one of which can be used to design a winning TARC entry. Read more

NAR and the AIAA have just released the objectives for the 2013 TARC season. In brief, they are
- Altitude mark of 750 feet
- Flight Duration of 48-50 seconds
- 15″ parachute must be used to recover the egg and the altimeter
- Egg must be placed horizontally (“lying on its back”)
- Section of rocket containing the egg must be at least 60 mm (2.362″) in diameter
- Gross liftoff weight of under 650 grams
- Motor impulse must be 80 newton-seconds or less
At first glance. this seems simple; after all, each of these has been used in past years. No surprises, so pretty easy challenge for the TARC teams, right? Read more

Westminster Christian Academy won the regional TARC contest March 17, 2012 in the best attended launch since HARA began hosting the event at Bragg’s farm. Westminster Christian has been in TARC since 2006 with only modest results each year, but this team scored a ‘4’ for a school record. These points are likely good enough for an invitation to the finals in Virginia, May 12.

Westlawn Middle School took second place and Williams Middle was third. Ten teams from seven schools participated and flew their egg carrying rockets in unseasonably warm and calm skies. This was twice the number of teams that came out last year so we thank everyone for supporting this very successful launch. There were a total of twenty-five TARC flights, most of which were for practice but ten were formal qualification attempts. Six flights were successful and scored points.
Liberty Middle 1 and Ridgeland High of Rossville, Ga. made practice flights only. Ridgeland’s second flight was great and would have been a ’27,’ but rocket damage in a subsequent flight kept them from attempting points. Madison Academy had parachute deployment problems and Bob Jones had an uncooperative altimeter.
All capsules contained two eggs and had to be flown on an “F” motor or less. The target altitude was 800’ but those flights that hit the 43-47 second duration window were rewarded with a zero time deduction.
This year’s trophies
The trophies were beautiful models donated by United Launch Alliance and were awarded to the top three places. Over seventy people were on hand to watch the launches. Vince Huegele and Bill Cooke provided the local officiating to qualify the flights as well as mentoring the teams throughout the year. Teams have until the deadline on April 2 to complete their qualification attempts.
Vince Huegele presents the first place award to Westminster Christian Academy team members Charles Nottingham, Nicholas Kromann (Team Lead), Ben Cyr, and Shane Nelson.
Ray Cole and David Bishop also had the HARA range set up for whatever members wanted to fly. There were 27 sport flights, nine of which were HP and three of them L1 certification attempts.
