About this observatory

The DeSS Deimos Sky Survey observatory sits in a protected dark-sky reserve in Ciudad Real province, central Spain, where it keeps a constant watch on the sky for hazards from space.

About DeSS Deimos Sky Survey observatory

DeSS is operated remotely from Puertollano, about 35 kilometres to the north, by the aerospace company Elecnor Deimos. The observatory's purpose is to detect and track near-Earth objects and space debris, helping to warn satellite operators of possible collisions and flag objects that could re-enter the atmosphere.

Telescopes & research

The site operates four telescopes dedicated to this survey and tracking work, forming part of the broader effort to monitor objects that could threaten satellites or, in rare cases, approach Earth.

Location & getting there

The observatory is located near Almodóvar del Campo in Ciudad Real province, within the Valle de Alcudia y Sierra Madrona Nature Reserve, an area valued for its dark, unpolluted skies.

Visiting DeSS Deimos Sky Survey observatory

As a remotely operated tracking facility rather than a visitor centre, DeSS does not appear to offer regular public tours. Check with Elecnor Deimos or local tourism resources for the nature reserve if you are travelling to the area.
