What is HASP?
HASP = High Altitude Student PlatformNASA-fundedOperated by Louisiana State UniversityZero-pressure balloon platformDesigned to float at ~120,000 feet for 20 hoursOne launch per yearRoom for twelve student experiments

The HASP Platform
• HASP is a 2000 pound payload
• Carried by an 11 million cubic foot zero pressure balloon

Scientific Goals•To capture and verify particles of cosmic origin•Balloon flights captured the first cosmic dust material and are similar to the NASA ER-2 flights•Cometary dust gives us information about the formation of our solar system 4.6 billion years ago and about the very edges of the solar system•Possible capture of material from known Trans-Neptunian Objects

Travel to JSC
Several BOREALIS members traveled to the Cosmic Dust Lab at Johnson Space CenterWe learned about the particle capture and analysis processMany of the second flight’s improvements were based on knowledge gained here
