Students searching for lost weather balloon, payload in White Hall

A group of high school students studying atmospheric pressure and temperature is searching for a weather balloon and payload of research equipment they think disappeared somewhere in White Hall.

The students, from Little Red School House and Elisabeth Irwin High School in New York City, launched the balloon about 9 a.m. Sunday from Chambersburg, Pa. But they lost radio contact with it about 15 minutes later, and they were unable to track it, junior Alexander Daley said in an e-mail.

Their flight predictions suggested that a payload including weather sensors and cameras landed about 11:45 a.m. near Greystone Golf Course in northeastern Baltimore County, "but it realistically could be anywhere in that region," Daley said.

The students were taking measurements on atmospheric pressure and temperature, as well as studying the efficiency of solar panels at altitude. The payload was also equipped with cameras to take pictures and video from an altitude of 100,000 feet.

The payload, a large box covered in silver plastic and red tape, may be attached to a parachute and burst weather balloon. The students' contact information is on the box, but anyone who saw it or finds it can contact them at
