ESA's Science Programme Committee approved a proposal to extend the operation of the Ulysses spacecraft ~ a joint project of ESA and NASA ~ until March 2008. NASA had already approved continuing the spacecraft's operations. The two space agencies had designed the spacecraft to study the heliosphere, a region of space influenced by the Sun and its magnetic field. Scientists of the agencies hoped that the continued operations of Ulysses would help them better understand the Sun. Since the 1990 launch of Ulysses, ESA and NASA both had launched additional fleet of solar and heliospheric spacecraft: NASA's Cassini, ESA's four Cluster satellites, and another collaborative project between ESA and NASA, the Solar and Heliospheric Observatory (SOHO).
