Ulysses mission coming to end
Ulysses,a joint mission between ESA and NASA to study the environment of space above and below the poles of the Sun coming to an end. Ulysses has been in the space for 17 years which is more than four times its expected lifetime. The power to the spacecraft supplied from a radioactive isotope, has been steadily dropping. Now the spacecraft no longer has enough power to run all of its communications, heating and scientific equipment simultaneously.
