Balloon Launch Uses Vernier Technology

The FIRST LEGO® League Team from Reston, VA recently took part in the High Altitude LEGO Extravaganza (HALE) balloon launch. Their payload included a LEGO NXT Robotics System with a Vernier NXT Adapter and two Vernier sensors—a UVB Sensor and a Surface Temperature Sensor.

They measured UV radiation as a function of altitude as the balloon rose to almost 100,000 ft. over Nevada. The NXT controlled a rotating pinwheel that moves different materials in front of a Vernier UVB Sensor. A Vernier Surface Temperature Sensor was used to control the temperature inside the payload area.

They recovered their payload after the flight and retrieved the data. The experiment seems to have worked quite well.

The team’s mentor was David Levy. See a video of the launch and get more information at www.unr.edu/nevadasat/hale/
