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:
“I have been accustomed to make excursions to the ponds within ten miles of Concord, but latterly I have extended my excursions to the seashore.”
—Henry David Thoreau (1817–1862)
“... [a] girl one day flared out and told the principal “the only mission opening before a girl in his school was to marry one of those candidates [for the ministry].” He said he didn’t know but it was. And when at last that same girl announced her desire and intention to go to college it was received with about the same incredulity and dismay as if a brass button on one of those candidate’s coats had propounded a new method for squaring the circle or trisecting the arc.”
—Anna Julia Cooper (1859–1964)
