Agnirva Space Premier League - Expedition #31678: High School Innovation in Orbit: Polyurethane Repair Kit from South Houston Students

When you think of spacecraft repair tools, what comes to mind? Perhaps high-tech gadgets or robotic arms? Now imagine students from South Houston High School crafting a polyurethane repair kit that was tested in orbit on the International Space Station (ISS). This educational initiative demonstrates not only the versatility of young minds but also how practical problem-solving skills can be developed at the high school level for real-world space applications.

Polyurethane is a common and adaptable material used for sealing, insulation, and repair in various industries. The student-designed repair kit aimed to determine whether polyurethane could serve as a reliable solution for patching leaks or damage on spacecraft in the unique environment of space. Unlike Earth, microgravity can alter how substances mix, cure, and adhere to surfaces, so conducting this test aboard the ISS was essential.

This project provided students a hands-on opportunity to engage with engineering and material science, experiencing the full lifecycle of a real space experiment—from hypothesis and prototype to testing in low Earth orbit. It also highlighted the importance of backup solutions for in-flight repairs, which are critical for astronaut safety and mission success.

The students’ polyurethane kit had to meet strict NASA safety and operational standards, which included fire resistance, non-toxicity, and containment. Once on the ISS, astronauts followed the provided instructions to test the material's application and curing behavior in microgravity.

The success of this experiment paved the way for further investigations into using flexible, student-created materials in future missions. It also proved that the next generation of space innovators could start making significant contributions while still in high school.
