Looking at this site, are there any interesting activities going on miniaturizing cameras? Is the research stalling? The papers here are at least 8 years old. Besides Avi Loeb any other prominent researchers?
Project Breakthrough Starshot aims to reach the Alpha Centauri system within the first half of the 21st century, with microprobes traveling at 20% of the speed of light propelled by around 100 gigawatts of Earth-based lasers. The probes would perform a fly-by of Proxima Centauri to take photos and collect data of its planets' atmospheric compositions. It would take 4.25 years for the information collected to be sent back to Earth.
The Centauri Prime is waiting!
