Aggies always aim high, and some Aggies are aiming for the skies-186 miles above Earth in fact!
For two years, the AggieSat Lab has been working on the picosatellite AggieSat2, a 5-inch cube, and it’s now ready for launch.

AggieSat2, shown being weighed before being shipped off, is scheduled to travel into space on Space Shuttle Endeavour on July 11.
The AggieSat Lab is a Student Satellite Program under the Department of Aerospace Engineering at Texas A&M University.
“AggieSat2 is built from scratch by our students; it’s a student-made student-operated satellite” says John Graves, a graduate student who worked on the satellite.
AggieSat2 is one of two satellites that is slated for launch on July 11 from Kennedy Space Center, Fla. The other satellite, Bevo-1, has been built by students from the University of Texas. Both satellites differ in design but are identical in function.
This mission-DRAGONSAT-is the first of four missions planned for an eight-year campaign, called LONESTAR, with NASA’s Johnson Space Center to demonstrate autonomous rendezvous and docking (ARD), a process in which space crafts that are apart in space meet (rendezvous) and join to form a single unit (docking) without human control. The first three missions will test the sensors, computers, navigation system, control system, communications system and GPS that will be required for the final mission. The final mission will conclude with the successful docking of two satellites. NASA plans to use ARD in its Constellation Program for unmanned cargo vehicles and in space assembly.
This first mission is intended as an “ice-breaker to get students used to building satellites” Graves explains. Students from the two universities worked closely to design pin systems needed for the satellites to lock into each other and spring-loaded antennas that would allow the satellites to separate.
AggieSat2 and Bevo-1 will be joined when they are launched into space on the Space Shuttle Endeavour. The shuttle will visit the space station, and 15 days later, the satellites will be released. The satellites will then separate and go into orbit, around 186 miles above Earth. Once in orbit, AggieSat2 and Bevo-1 will beam information about their position by using the on-board GPS, called DRAGON, developed by Johnson Space Center. Information from the satellites will be transmitted to a ground control station-the ground station for AggieSat2 is set up on the Riverside campus- and collected by students. The information will be sent to NASA, where it will be compared with NASA’s predictions to check the new GPS for accuracy. The mission will be considered a success after this information has been completely received by the ground control station and delivered to NASA.

“Building AggieSat2 provided students with an unparalleled learning experience,” Graves says. “It’s easy to conceptualize on paper, but building AggieSat2 provided a real-world experience that cannot be obtained in classrooms. We had to deal with every little problem at every stage and ensure that the satellite passed rigorous testing.”
The AggieSat Lab was set up in 2005 by Dr. Helen Reed, a professor in the Department of Aerospace Engineering. The lab aims to provide students with hands-on engineering experiences. Students apply concepts learned in classes, learn about systems engineering and industry practices, and create novel technologies.
“The launch of AggieSat2 is a tribute to the dedication, creativity, and teamwork of our students,” says Dr. Reed, the lab’s principal investigator and primary mentor. “Our students have had to pass every review with NASA that a usual satellite would. What an accomplishment to be able to say that you have launched a satellite while in school!”
The AggieSat Lab is sponsored by NASA’s Johnson Space Center, Lockheed Martin, MEI Technologies, Oceaneering Space Systems, PM&AM Research, Department of Defense Space Test Program and Spreadsheet World.
The AggieSat Lab will be tracking, communicating with, commanding, and collecting data from AggieSat2 through the Riverside ground station. For more information on the latest launch and updates on mission operations, visit: http://aggiesat.org.
