I saw this reported in BIS-Spaceflight.<br>
(I'm usually a few months behind in reading it) I like the "first objective"!<br>
<br>
<a href="https://www.thalesgroup.com/en/worldwide/space/press-release/ascend-thales-alenia-space-lead-european-feasibility-study-data" rel="noreferrer noreferrer" target="_blank">https://www.thalesgroup.com/en/worldwide/space/press-release/ascend-thales-alenia-space-lead-european-feasibility-study-data</a><br>
<br>
Cannes, November 14, 2022 – Thales Alenia Space, the joint company between Thales (67%) and Leonardo (33%), has been chosen by the European Commission to lead the ASCEND (Advanced Space Cloud for European Net zero emission and Data sovereignty) feasibility study for data centers in orbit, as part of Europe’s vast Horizon Europe research program.<br>
<br>
Digital technology’s expanding environmental footprint is becoming a major<br>
challenge: the burgeoning need for digitalization means that data centers in Europe and around the world are growing at an exponential pace, which in turn has a critical energy and environmental impact.<br>
<br>
The first objective of this study will be to assess if the carbon emissions from the production and launch of these space infrastructures will be significantly lower than the emissions generated by ground-based data centers, therefore contributing to the achievement of global carbon neutrality. The second objective will be to prove that it is possible to develop the required launch solution and to ensure the deployment and operability of these spaceborne data centers using robotic assistance technologies currently being developed in Europe, such as the EROSS IOD demonstrator.<br>
<br>
This project is expected to demonstrate to which extent space-based data centers would limit the energy and environmental impact of their ground counterparts, thus allowing major investments within the scope of Europe’s Green Deal, possibly justifying the development of a more climate-friendly, reusable heavy launch vehicle. Europe could thus regain its leadership in space transport and space logistics, as well as the assembly and operations of large infrastructures in orbit.<br>
