Extended Mission
According to its original design, AMS-02 was to be returned to Earth on a shuttle flight after its superfluid helium supply (used to cool the superconducting magnet solenoid) was exhausted. Because the superconducting system could not be made to work reliably, lower sensitivity non-superconducting magnets were employed, eliminating the need for superfluid helium. The experiment additionally is too large and heavy to return to Earth after the retirement of the shuttle, and the plan is therefore now to leave the unit in place on the space station exterior.

Famous quotes containing the words extended and/or mission:
“The civility which money will purchase, is rarely extended to those who have none.”
—Charles Dickens (1812–1870)
“Every Age has its own peculiar faith.... Any attempt to translate into facts the mission of one Age with the machinery of another, can only end in an indefinite series of abortive efforts. Defeated by the utter want of proportion between the means and the end, such attempts might produce martyrs, but never lead to victory.”
—Giuseppe Mazzini (1805–1872)
