ESTEC entrance road

The way in to ESA’s technical heart – set to be visited by thousands of members of the public during the Sunday 4 October ESTEC Open Day.

Nearly 3000 people work at ESTEC, ESA’s single largest establishment, which has been in the business of technology development in support of space missions for half a century now.

The flags of ESA’s Member States flutter ahead of the establishment’s main building. Note the full-scale model of the 1991-launched radar Earth observation mission ERS-1, at the right.

ESTEC hosts specialist teams skilled in every aspect of the space environment, a suite of technical laboratories, a centre for human spaceflight and the biggest spacecraft testing facility in Europe.
