"This gazetteer contains detailed information about all names of topographic and albedo features on planets and satellites (and some planetary ring and ring-gap systems) that the International Astronomical Union (IAU) has named and approved from its founding in 1919 through the present time." I still can't believe we actually called a geological feature 'Baba Jaba Chasma'. As soon as I gather my team of Firewall agents they'll have to do some super-important mission on Venus, I think.
