Welcome to The GPSL Website!

The Great Plains Super Launch is the premier conference for near space explorers and enthusiasts dedicated to the education and study of aerospace science via Amateur Radio High Altitude Ballooning.

Our Hosts
St. Louis Area Robotics Club ROBOMO is a club for people of all ages and experience levels who are interested in amateur robotics, electronics, and even a bit of amateur radio. Our members come from a very diverse background and are interested in a wide variety of robotic topics including telepresence, near space payloads, mini sumo, line following, mini magellan, special “one of a kind” projects, and more. Our members are always willing to share their knowledge and experiences with each other with the common goal of learning about robotics and electronics and having a bit of fun along the way.

What is Near Space?

Near space is that region of the atmosphere above 60,000 feet but below the accepted altitude of space, 328,000 feet. These altitudes make near space far more like earth orbit than the surface of the earth. Air pressure in near space reaches 99% of a vacuum or better. Air temperatures drop to a low of -60 degrees F or colder. Cosmic radiation is over 100 times greater than at sea level. Near space is located within the ozone layer and therefore is an environment of increased damaging ultraviolet radiation. Near space is reached by helium or hydrogen-filled weather balloons. Since it is far less expensive to send payloads into near space than earth orbit, organizations like NASA will send new designs into near space first, as a test.
