You may have heard about how organizations use satellites and drones to capture useful images of the Earth -- high-resolution pictures that can help people understand how changes on the ground will impact their business or people's lives. For the past five years, the aerospace startup Near Space Labs (NSL) has provided similar imagery -- using a fleet of balloons that flies in the stratosphere.
Now, NSL is making its high-resolution imagery of Earth available for free to universities, nonprofit organizations, and researchers, the company announced Wednesday.
NSL offers images with 10-centimeter-per-pixel resolution. The images are so clear they can pick up road conditions, roofing details, vegetation, or even a soccer ball on the ground. There are a number of commercial use cases for NSL's technology. Insurance companies, for instance, could use it for property assessments, while energy companies could use it to monitor their solar panels or oil fields.
Now, with its Community Resilience & Innovation Earth Imagery Grant program, NSL will release imagery of the most populated cities in the US. NSL says it wants to make the imagery available to organizations that need them but cannot obtain them otherwise.
"We want to provide the most recent and high-quality data on the market to not only our enterprise customers, but to those doing equally important work for the betterment of our overall society," NSL co-founder and CEO Rema Matevosyan said in a statement.
"It is our hope that our ability to extend access of our imagery database to a broader set of researchers and those who have a limited budget will allow them to gain a more comprehensive understanding of their analyses as they work to identify key issues and develop solutions to the challenges we face every day within our cities, suburbs, and rural areas."
So, how does it all work? High-altitude balloons make the mission at NSL possible. They carry a small, autonomous robot called Swifty to capture the world around them at high resolution with zero carbon emissions. The balloons fly between 60,000 and 85,000 feet in the air, allowing Swifty to capture photos that cover up to almost 1,000 square kilometers.
A significant difference between NSL's unique space balloons and a typical satellite is that weather conditions don't inhibit NSL's balloons, as the balloons can enter the stratosphere immediately after inclement weather. By comparison, satellites cannot assume another position until they complete a full orbit. So, if cloudy weather hinders a satellite from capturing images, part of the orbit becomes a waste of time and money.
NSL's Swifty can capture changes in the environment daily, such as progress on a construction project or property damage from a natural disaster.
Well, what about airplane imagery? Compared with Swifty, airplanes are too slow, too expensive, and don't pay enough attention to rural areas, NSL argues. By contrast, Swifty can be thrust into the sky above commercial airspace immediately after severe weather and can easily hover over rural American locations.
Lastly, Swifty can capture images at a scale equivalent to all five boroughs in New York City combined. Carried by balloons, Swifty can also fly unmanned, without human navigation, unlike drones. Drones must adhere to federal aviation regulations and can only fly for short periods, unlike Swifty.
Since the Swifty system operates at a lower cost with increased efficiency and zero carbon emissions, NSL and other companies using the same technology could be seen has having a leg up on traditional satellite imagery. It might be only a matter of time before the sky is filled with autonomous robots sitting atop balloons.
