European space chiefs back photonics-enabled missions

Biggest ever European Space Agency budget to support gravitational wave interferometer, optical space network, and a series of new remote sensing payloads.

The European Space Agency (ESA) council of ministers has approved what is being described as the organization’s most ambitious plan to date, with a significant boost in funding set to support several photonics-enabled missions.

Among those expected to benefit are the laser interferometer space antenna (LISA) – the first gravitational wave detector deployed in space – as well as a fiber-like laser communications network in the sky, and six new “Sentinel” Earth observation missions that will rely on a variety of photonics technologies.

The plan, said to represent a commitment to the ESA’s biggest-ever budget, also includes support for the “ATHENA” X-ray telescope, to study black holes in unprecedented detail.

Although further commitments to funding from ESA’s member states will be required to guarantee the various mission launches, the latest backing is seen as a major step towards achieving that.

Pushing boundaries

Following a two-day summit of ESA ministers in Seville, Spain, the agency announced: “For the first time in 25 years, there will be a significant boost in funding for ESA’s world-class and inspirational science program, pushing the boundaries of our understanding of who we are and where we come from.”

The agency’s director general Jan Wörner added: “Together we have put in place a structure that sees inspiration, competitiveness and responsibility underpin our actions for the coming years, with ESA and Europe going beyond our previous achievements with challenging new missions and targets for growth along with the wider industry.”

In total the ESA’s 22 member countries – which include Canada, Switzerland and Norway from outside the European Union – have pledged €14.4 billion towards future efforts, at a rate of €4.2 billion per year.

The largest individual contributor to that total is Germany, whose representatives have pledged to provide €3.3 billion. France, Italy, and the UK are the next highest contributors, and together the four countries are providing nearly 70 per cent of the total.

The biggest chunk of the budget, equivalent to €2.54 billion, will be allocated to Earth observation activities. Under its Copernicus program, ESA has already launched an extensive network of Sentinel satellites that collect data including high-resolution optical and multispectral imagery of Earth, to assist with land and ocean monitoring, climate studies, weather forecasting, and much more besides.
