Agnirva Space Premier League - Expedition #31243: LightCube: A Flash of Light from Space for Student Science

What if you could send a text message to space—and get a flash of light in return? That’s the idea behind LightCube, a student-driven CubeSat project developed at Arizona State University with support from Vega Space Systems. LightCube flew on Expedition 68 to test a simple but thrilling concept: enable anyone with a HAM radio license to interact directly with a satellite.

The satellite contains a xenon flash tube that emits a visible light burst in response to radio signals from the ground. This allows users to engage with space technology in real time, making LightCube a beacon for public engagement and STEM education.

Led by Jaime Sanchez de la Vega, the project serves as a proof-of-concept for democratized space access. It empowers students and amateur radio enthusiasts to become part of the space ecosystem—not just as spectators, but as participants.

Beyond its flashy interaction feature, LightCube also serves as a testbed for compact electronics, power systems, and communication protocols in CubeSats. Its small size and low cost make it a model for future educational satellites.

LightCube lights the way—literally and figuratively—for a new generation of space explorers.
