Model rockets built by students at Stone Memorial High School will be launched again this spring in the Crossville area. Under the supervision of instructor Tom Tatum, 10 students at SMHS have completed research and are now constructing rockets to qualify for the Team America Rocketry Challenge.

Students meet one day each week following classes to design their rockets, fabricate components and test fittings for the flight model. This year the group will build at least three similar models to carry their fragile payload.

The challenge this year is to launch a grade A hen's egg to an altitude of exactly 750 feet. From liftoff to landing, the flight time must be 45 seconds. A miniature altimeter is carried on board. Any altitude variance or flight time adds penalty points to the flight.

The egg must be returned safely by parachute. To add difficulty to this year's flight, the egg must lie on its side and not placed in an upright position in the rocket body.

Tatum said last year's team learned a great deal when the school qualified for the national fly-off.

"This year, we've got to carefully watch our spending. The club must seek non-school support. Components add up to more than $120 per flight rocket."

Each rocket costs about $25, Tatum added, so students this year are spending more time on computer design and simulations.

"Unfortunately, we may need to conduct 15 to 20 launches before we feel we're set to conduct our qualifying flights," Tatum said. "The competition gets keener every year."

Nationwide qualifying flights occur the first week of April. Over 650 schools, scout troops and 4-H groups are participating in the Challenge this year. Following the qualifying flights, the top 100 teams will be invited to the national fly-off May 15-17 near Manassas, VA.

Over $60,000 in prize money is awarded winning teams. The first place team is awarded an all-expense paid trip the Paris Air Show. Additional prizes include significant engineering scholarships to top team members.

The event is sponsored by the Aerospace Industries Association (AIA) and the National Association of Rocketry (NAR). The AIA is comprised of 33 U.S. aerospace firms. The NAR is a nationwide non-profit aero modeling organization that establishes model rocketry rules in the U.S.

Co-sponsors include the National Aeronautics and Space Administration (NASA) and Department of Defense (DOD). The American Association of Science Teachers and 4-H Science, Engineering and Technology office are education co-sponsors.

The River WILD!
The Big South Fork of the Cumberland River winds its way through the 125,000 acres of the Big South Fork National River and Recreation Area before flowing into the Cumberland River and Lake Cumberland in Kentucky. It’s a free-flowing river, with no dams to control release of the water, but the scenery and the magnificent rock formations make it a favorite of paddling enthusiasts who watch the weather to see if they can get out and explore areas that are hard to reach by foot.

Farmer's Market opens for business June 2
The Cumberland County Farmer’s Market will officially open the growing season as it has every year since 1978. This year’s “opening” will be Saturday, June 2, at the traditional location on Livingston Rd., next to the fairgrounds. Selling will begin early (6:30 a.m. or so), although some vendors may set up a few hours later in order to provide the freshest vegetables picked just that morning. There is usually a good selection until well after noon.

Around the Town: Children's letters to God
I received the cutest e-mail earlier this week and could not resist sharing it with Chronicle readers. The email contains a list of letters that children have written to God. I found them to be quite hilarious and feel sure you will as well. Please pardon the spelling as the notes were typed as the children wrote them:
