Our take
Satellite data is critical in order to solve some of the world's most pressing matters, such as climate change and the loss of biodiversity. While data and precise analytical tools able to draw insights are available, the problem is they lack interoperability between platforms and the ability to combine this data from different satellites is inaccessible.
Founded in 2015, Open Cosmos is a SpaceTech startup with the aim to simplify access to space. The company designs, manufactures and operates satellites that are part of its "Open Constellation". Meanwhile its platform, DataCosmos, makes satellite data access easier for organisations and governments, combining earth observation data from multiple sources to help with the mitigation of environmental and sustainability challenges.
Partnerships with organisations such as Innovate UK, ESA and the UK Space Agency are supporting Open Cosmos as it expands operations, growing its team and ideas. Most recently. the company revealed it will be manufacturing the first 6G satellite research lab, the 6GStarLab. A huge step for the company that will position it at the forefront of next-generation space-based communication.
