Guy Laliberte, the founder of Cirque de Soleil, and the man who paid $35 million to ride aboard a Russian spacecraft so he could draw attention to water scarcity on our planet, is back on terra firma.

A Russian Soyuz space capsule carrying Laliberte and a Russian-American crew, touched down safely on a vast steppe in northern Kazakhstan Sunday.  They had spent about two weeks in space.

The 50-year-old, who is worth an estimated $2.5 billion, hosted a show from the International Space Centre.

The show, aimed at highlighting the scarcity of water in many parts of the world, involved, singers, dancers and celebrities in 14 cities around the world. Organizers called the Moving Stars and Earth for Water spectacle the first of its kind to be hosted from space.

During the show, online viewers from as far away as Argentina, Australia and India were asked to sign ‘make a difference’ pledges to cut back on bottled water, install water savings devices in their homes, and also make other environmental savings.

Laliberte launched his non-profit One Drop Foundation in 2007 to increase access to clean water worldwide.

Millions of people in developing countries do not have access to clean water, and water-borne illnesses are a persistent problem in many impoverished regions.
