Agnirva Space Premier League - Expedition #32434: Bringing Supercomputers to Space: Image and Video Processing on the ISS

What if satellites could process high-resolution images and video right in orbit, without relying on delayed data downloads to Earth? This is the challenge tackled by the Spacecraft Supercomputing for Image and Video Processing experiment, part of the Space Test Program-Houston 6. Spearheaded by Dr. Alan George and his team at the University of Pittsburgh, this experiment is a leap into the future of onboard computing in space. In space missions, time-sensitive data such as imagery from natural disasters, military operations, or planetary reconnaissance is vital. Traditional space systems, however, depend on sending data back to Earth before processing. This round-trip delay can reduce the usefulness of the data. That’s where the idea of onboard supercomputing becomes revolutionary. The experiment deploys a small, high-performance computing system on the ISS designed to process image and video data in real-time. The computer must be robust against radiation and power fluctuations – two major challenges in space environments. Developed by SHREC and associated departments at the University of Pittsburgh, the supercomputer is specifically engineered to balance computational power, energy efficiency, and resilience. This onboard processing capability can detect important events immediately. For example, a satellite equipped with this system could identify wildfires or flooding as they happen, allowing near-instant alerts to emergency services on Earth. The implications extend to scientific missions as well. Processing video of volcanic eruptions, glacier calving, or urban expansion can provide real-time insights into Earth's dynamic processes. Additionally, space missions to other planets will increasingly depend on autonomy. Sending instructions to Mars, for instance, takes several minutes. With supercomputing capabilities on the spacecraft, decisions can be made locally – enhancing mission safety and effectiveness. By validating these technologies aboard the ISS, researchers aim to standardize onboard data processing for a new era of intelligent satellites and exploration vehicles.
