A tiny space hitchhiker named AO-85 is talking and thousands of ham radio operators worldwide and a handful of Vanderbilt University engineering researchers with the special interest of proud parents are listening.
AO-85’s transponder was turned on three days after the 4-inch by 4-inch, 2.2 pound CubeSat successfully deployed from an Atlas V rocket launched (video) by the United Launch Alliance in October from Vandenberg Air Force Base in California.
In reality, a successful deployment and a successful data transmission is somewhat rare in university CubeSat programs, giving the researchers reason enough for celebration.“When the deployment was successful and the beacon came on we had an ‘It’s alive!’ moment,” said Robert Reed, professor of electrical engineering and the principal investigator of Vanderbilt’s NASA-sponsored CubeSat project. “Then, the transmitter was turned on and we had a data stream sufficient to collect information to do research.”
The Vanderbilt project, however, differs from CubeSat efforts at other universities in an important way…..READ MORE
