Eon Space Labs' Mira Satellite: Tiny, Durable, and Powerful

A Hyderabad-based startup has built a telescope so small and durable that it splits light into invisible wavelengths to provide real-time health monitoring of crops from space. The engineers at Eon Space Labs have patented the innovative telescope as Mira. The unit weighs just 500 grams and is smaller than a coffee mug, which is lighter and smaller than ordinary satellites.

"A Telescope Smaller Than a Coffee Mug"

Its designers call it a CubeSat, but its size is not what defines it. A satellite's internal architecture decides its performance and durability. The miracle of Mira is that it does not rely on older mechanical parts subject to vibrations, temperature swings, and extreme forces during a rocket launch. CubeSats typically carry conventional optics that use heavy mechanical mounts susceptible to misalignment during launch. Each screw or separate mount adds a point of failure, making small satellites delicate instruments. The engineering challenge is making tiny telescopes with perfect alignment during launching and working flawlessly in space. The CubeSat relies on a monolithic block of fused silica carved to form the optical architecture. They remove the screws and internal mounts entirely. This one solid piece of highly pure glass keeps the instrument intact and optimally aligned. The heat-resistant material means there is no need to add parts to make spaceproof. The entire interior of the CubeSat is designed to work seamlessly with the monolithic optical block that serves as the telescope. Carving the entire optical architecture into one solid piece ensures a unified optical path. The satellite splits light into nine distinct bands, including invisible infrared, creating multispectral imagery to reveal hidden details that normal cameras cannot.

Eon Space Labs' Mira telescope has evolved alongside the global rise of SmallSats. Micro-miniaturization has progressed thanks to improving lithography and etching technologies. Eon Space Labs' innovation has popularized the CubeSat form factor, which can carry complex instruments like optical telescopes and be configured for specific missions. The patented technology has early applications in agriculture. Onboard AI analyzes the spectral bands from the telescope to spot crop diseases in real time. By using satellite observations, farmers can promptly intervene to protect crops.

The fused silica material used to make the telescope is highly resistant to heat, cold, and physical stress, so it maintains a perfect alignment of the telescope despite massive temperature swings in space. By splitting the incoming light into nine separate bands, both visible and invisible, this system captures more data better than the best land-based telescopes. Agricultural intelligence from orbit. Combined with AI to provide actionable insights to farmers, it could revolutionize precision farming. The onboard AI can analyze these spectral bands to detect crop diseases in real-time. This could allow farmers to detect anomalies and respond to crop diseases without delay, previously impossible.

"Unlocking Spectacle"

The developers aimed to improve accuracy and precision over existing methods. Traditional satellite optics can misalign during launch. CubeSats with telescopes are still relatively rare but are expected to grow in popularity as more satellite developers seek to launch low-cost, high-utility missions. CubeSat telescopes could help address these issues and pave the way for other CubeSat instruments.

"Seeking the crop disease Genome"

Most CubeSats are small and fragile with limited lifespan, but this patented architecture could make CubeSats last longer. Multiple mechanisms ensure that the telescope can withstand a wide range of temperatures and still maintain its optimal alignment. A monolithic block means it's physically coherent. Moreover, it can withstand the extreme vibration of a rocket launch.
