 Artist's concept of the Rosetta mission's Philae lander on the surface of
comet 67P/Churyumov-GerasimenkoRosetta comet landing coverage

NASA Television and the agency’s website will provide live coverage from
9-11:30 a.m. EST (6-8:30 a.m. PST) of the European Space Agency (ESA)
*Rosetta* mission’s scheduled landing of a probe on a comet on Wednesday,
Nov. 12.

NASA's live commentary will include excerpts of the ESA coverage and air
from 9-10 a.m. NASA will continue carrying ESA's commentary from 10-11:30
a.m. ESA’s Philae (fee-LAY) lander is scheduled to touch down on comet
67P/Churyumov-Gerasimenko at 10:35 a.m. A signal confirming landing is
expected at approximately 11:02 a.m.

After landing, Philae will obtain the first images ever taken from a
comet's surface. It also will drill into the surface to study the
composition and witness close up how a comet changes as its exposure to the
sun varies. Philae can remain active on the surface for approximately
two-and-a-half days. Its “mothership� is the Rosetta spacecraft that will
remain in orbit around the comet through 2015. The orbiter will continue
detailed studies of the comet as it approaches the sun and then moves away.
NASA has three of the 16 instruments aboard the orbiter.

Comets are considered primitive building blocks of the solar system that
are literally frozen in time. They may have played a part in "seeding"
Earth with water and, possibly, the basic ingredients for life.
