       PARIS, Oct 7 (Reuters) - Europe's Hera asteroid probe
blasted off from Florida on a SpaceX rocket on Monday, beginning
a two-year voyage to revisit an asteroid bashed off course by
NASA's DART spacecraft in 2022.
    The return visit to the Dimorphos asteroid two years after
the historic collision marks the latest step in efforts to see
whether an incoming small asteroid could, if needed, be
deflected from Earth to prevent potentially widespread damage.
    A Falcon 9 rocket carrying the probe lifted off at around
10:53 a.m. local time (1453 GMT), according to a live webcast.
    The European Space Agency selected Elon Musk's SpaceX for
the launch to fill a gap in Europe's own access to space.
    Dimorphos is a moonlet of Didymos, which is defined as a
near-Earth asteroid. 
    DART (Double Asteroid Redirection Test) was a
proof-of-concept mission designed to use a spacecraft to nudge a
celestial object that might otherwise strike Earth. Dimorphos
and Didymos do not pose an actual threat to Earth.
    The spacecraft collided on Sept. 26, 2022, at about 14,000
miles per hour (22,530 kph) into Dimorphos, roughly 6.8 million
miles (11 million km) from Earth. 
    Scientists said in March that the collision changed not only
the small asteroid's path but its shape as well.
    Built by Germany's OHB SE  OHBG.DE , Hera will conduct a
post-impact survey of Dimorphos in order to help expand the U.S.
space agency's experimental collision two years ago into a
repeatable strategy for planetary defence, according to ESA.
    There are more than half a million asteroids in the Solar
System, of which over 25,000 are classified as near-Earth
objects. Of these, more than 1,000 are in ESA's risk list,
meaning that they merit close follow-up observations, according
to the agency.
