Delivers Destiny Lab to International Space Station
Space Shuttle Atlantis spent almost 13 days in orbit, with
seven of those days docked to the International Space Station.
While at the orbital outpost, the STS-98 crew delivered and
activated the U.S. Laboratory named Destiny and completed
three space walks.
of the Destiny Lab brought the space station's mass to about
101.6 metric tons (112 tons), surpassing that of the Russian
Mir space station for the first time.
Specialists Tom Jones and Robert Curbeam conducted three space
walks during the mission that totalled nearly 20 hours. During
the first space walk they assisted shuttle robot arm operator
Marsha Ivins in moving Pressurized Mating Adapter 2 and installing
Destiny onto the station. During the second space walk, they
focused on moving Pressurized Mating Adapter 2 from a temporary
position to its new home at the forward end of Destiny. Jones
and Curbeam spent most of their third space walk connecting
cables and equipment outside Destiny. Then, they performed
some procedural tests to determine the best ways to help a
disabled space walk partner.
