South Africa is thought for exporting uncooked minerals, fruit and wine, however what might be not that well-known is that it has a thriving area business that provides satellite tv for pc elements and companies globally. South African area merchandise are integrated into a large number of worldwide satellites. Exports generated by the nation’s area business amounted to round R200 million in 2022. Stellenbosch area know-how options supplier, Dragonfly Aerospace is constructing on that historical past and has offered ‘eyes within the sky’ for a number of missions in area. CEO and Founding father of Dragonfly Aerospace, Bryan Dean informed BizNews that the corporate’s know-how has been constructed on the know-how that has been developed in Stellenbosch for the reason that 90s. Dragonfly Aerospace has a digital camera that has been flown to an asteroid and in January 2023, they launched the primary of a seven-satellite constellation in low earth, referred to as the EOS SAT-1 from Cape Canaveral on a Area X rocket to watch agriculture. – Linda van Tilburg

Constructing high-performance cameras for area
We construct cameras for area, , from fairly small cameras in regards to the dimension of your fist as much as huge cameras, the scale of a giant fridge. So, , fairly a spread of efficiency that you simply get from these totally different cameras. After which clearly, dimension complexity, and value will increase as you go up as nicely. So a spread of various prospects all over the world purchase our merchandise. Yeah. I imply, on the whole, these are high-performance devices, , so akin to astronomy telescopes, , massive mirrors. They’re mirror-based reflecting telescopes with sensing electronics behind them. We fly these in area at seven kilometres a second, flying all over the world. A satellite tv for pc orbits the earth in about 90 minutes, flying at seven kilometres a second. So, these cameras don’t work like a snapshot digital camera that you simply might need in your cellphone or you’ll have had a point-and-click previously the place you’re taking a snapshot. These work much more like a scanner. So, you’re taking a line of pixels and then you definitely scan that throughout the floor of the earth as you fly.

From flying a digital camera to an asteroid to launching a satellite tv for pc from Cape Canaveral on a Area X rocket
That was a significant step for us. I imply, we’ve offered plenty of cameras and we’ve bought a whole lot of cameras flying in orbits already. I imply, we bought a digital camera that’s flown to an asteroid. There was a NASA dart mission, which was fairly huge within the media just a few months in the past. It was a collaborative South African affair as a result of a South African massive telescope in Sutherland imaged the asteroid affect concurrently our digital camera flying 1 million kilometres from Earth was imaging it from just a little satellite tv for pc. So, we’ve had plenty of actually thrilling missions in area earlier than. However, in all of those instances we have been delivering the digital camera to our buyer who was constructing the satellite tv for pc, who was setting up the mission, defining what the applying was and constructing a system that will carry out that software. However within the case of the satellite tv for pc that we launched in January, the entire thing was our creation. Once more, we had a buyer who was searching for agricultural monitoring, however we constructed a system that was optimised to realize that objective. It was a giant system, 180 kilograms satellites, two massive cameras, every one with an aperture of 250 millimetres and a metre lengthy digital camera, two of these side-by-side to provide you a large swath as a result of this is a gigantic space, a big space of crop on the earth and also you wish to be masking this recurrently to have the ability to function many shoppers as doable.
The entire thing was built-in in Stellenbosch after which shipped from our facility right here to america from the place it went to Cape Canaveral and launched on a SpaceX Falcon 9, which was fairly thrilling as a result of I used to be there for the launch and the rocket landed once more after launching our satellite tv for pc into area.

South Africa’s satellite tv for pc business is a Stellenbosch story
The center of all satellite tv for pc engineering in South Africa is in Stellenbosch. This can be a satellite tv for pc program that was developed within the late eighties, and early nineties, which was developed by Armscor on the time. So, that was a authorities program. The satellite tv for pc for that program was referred to as GreenSat, it was developed fairly far, however it was by no means launched. South Africa was growing a launch automobile on the similar time, a rocket. The Overberg take a look at vary was the launch website. So, within the late eighties, and early nineties this plan was in place. You realize it didn’t get accomplished however a whole lot of the talents which can be getting used in the present day have been developed in that first program. Naturally, that first program is sort of intently tied to Stellenbosch College and that’s actually the place the guts of all of area enterprise in South Africa comes from now. So, there are fairly just a few area corporations in South Africa now, round about ten or so. They’re all not directly or different offshoots from both Stellenbosch College immediately or Stellenbosch College launched a satellite tv for pc in 1999 referred to as SunSet, which was constructed by college students. It was actually an incredible achievement as a result of it was fairly a high-performance satellite tv for pc with 64 kilograms and it was subsequently recognised to be one of the best satellite tv for pc of its class at the moment on the earth.

A dream of heavy business in area and earth as a nature reserve
The asteroid belt is one thing that we see as a future profit to Earth, the place we will use assets from the broader photo voltaic system, not simply assets from Earth. My dream can be that each one heavy business is in area and the earth is extra like a nature reserve. That will be a great final result for me. However whether or not or not it’s doable in our life on time or in any respect, actually stays to be seen. Nevertheless it’s actually a pleasant future if we will consider the Earth being a nature reserve.
