Future Solar System modules

As part of a NASA-funded project (sbpy), we will add a number of services to astroquery over the next three years. This list is just to provide a heads-up for everyone:

* [x] JPL Small-Body Database Browser (orbital and physical properties, https://ssd.jpl.nasa.gov/sbdb.cgi)
* [x] JPL Small-Body Database Search Engine (most likely, depends on JPL API development, https://ssd.jpl.nasa.gov/sbdb_query.cgi)
* [x] Minor Planet Center (observations database and ephemeris service, https://minorplanetcenter.net/)
* [x] IMCCE: INPOP, Miriade, Multisat, SkyBot (ephemeris tools and a tool to identify moving objects in a field of view at a given time, https://www.imcce.fr/fr/ephemerides/)
* [ ] Lowell ASTORB (ephemeris and physical properties, http://asteroid.lowell.edu/)
* [ ] Solar System Object Image Search function of the Canadian Astronomy Data Centre (http://www.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/en/ssois/)
* [ ] other services we are considering are NEODyS (orbital elements and uncertainties for near-Earth objects, http://newton.dm.unipi.it/neodys/) and ASTDyS (orbital elements and uncertainties for other asteroids, http://hamilton.dm.unipi.it/astdys/)
* [x] JPL Molecular Spectroscopy Catalog (which includes the partition functions needed for sbpy spectroscopy analysis, [https://spec.jpl.nasa.gov/](url))

If you are interested in additional services, please reply to this thread and I will add them to the list.

The issue is a roadmap rather than a scoped task: review the unchecked Lowell ASTORB and CADC SSOIS entries and their linked service pages first. A contribution would need a selected service, a defined module scope, and completion criteria before implementation can be judged.
