  There is a vibrant and effective planetary science community in Canada. We do
research in the areas of meteoritics, asteroid and trans-Neptunian object
orbits and compositions, and space weather, and are involved in space probe
missions to study planetary surfaces and interiors. For Canadian planetary
scientists to deliver the highest scientific impact possible, we have several
recommendations. Our top recommendation is to join LSST and gain access to the
full data releases by hosting a data centre, which could be done by adding to
the CADC, which is already highly involved in hosting planetary data and
supporting computational modelling for orbital studies. We also support MSE,
which can provide spectroscopy and thus compositional information for thousands
of small bodies. We support a Canadian-led microsatellite, POEP, which will
provide small body sizes by measuring occultations. We support the idea of
piggybacking space weather instruments on other astronomical space probes to
provide data for the space weather community. Many Canadian planetary
scientists are involved in space probe missions, but through haphazard and
temporary arrangements like co-appointments at US institutions, so we would
like the community to support Canadian researchers to participate in these
large, international missions.
