Free Satellite Images

Commercial activity in space relies heavily on satellite launches and should not be expected to change in this area in 2022. This growth in the sector is driven by the fact that launching satellites into orbit is cheaper every year, and at the same time, the number of use cases is growing. GPS and satellite imagery are used today in many areas of human activity, and the list is expanding.

Reports in recent years have shown that launching a satellite is now comparable to the cost of launching an application. Large companies and start-ups can now use the technological capabilities of remote sensing. Moreover, in 2022, Fleet Space Technologies plans to launch satellites printed on a 3D printer. Satellites are getting smaller and lighter, which has allowed the Chinese company Galaxy Space to launch about 1,000 small satellites. They are used in sectors such as aviation, automotive, and shipbuilding.
