Philae’s primary landing site will target Site J, the centre of which
is indicated by the cross in this OSIRIS narrow-angle image.
J is located on the head of Comet 67P/Churyumov–Gerasimenko and is
close to the candidate site B, the large depression to the right of the
Site J offers the minimum risk to the lander in comparison
to the other candidate sites, and is also scientifically interesting,
with signs of activity nearby. At Site J, the majority of slopes are
less than 30º relative to the local vertical, reducing the chances of
Philae toppling over during touchdown. Site J also appears to have
relatively few boulders and receives sufficient daily illumination to
recharge Philae and continue science operations on the surface beyond
the initial battery-powered phase.
