ESA is taking a significant step towards realising the Solar System Internet (SSI) - an ambitious vision made possible through global collaboration. Earlier this year, ESA launched a concurrent design activity for the SSI Node-1 mission, the world’s first mission aimed at demonstrating a reliable, routine optical communication link from the Moon to Earth.

The beginning of the industrial development of LISA was among the highlights for the European Space Agency on the second day of the International Paris Air Show. 

One of the biggest Earth observation conferences in the world will take place next week in Vienna. You can watch streamed plenary discussions and presentations each day on ESA Web TV.

Today, the European Space Agency (ESA) and OHB System AG sealed their agreement to build ESA's Laser Interferometer Space Antenna, LISA. A bold scientific enterprise, the triple-spacecraft mission will be the first space-based observatory to study gravitational waves: ripples in spacetime caused by the most powerful events in the Universe, such as pairs of supermassive black holes colliding and merging.
