John Batchelor and I welcomed Dr. Jeff Foust back to Hotel Mars. During our 12 minute Hotel Mars segment, we talked about significant space events and missions during 2014 including the recent methane discovery on Mars, Curiosity findings, Space X & Orbital Science 2014 events, the Rosetta mission, New Horizons to Pluto, and the Dawn mission. Virgin Galactic’s accident was reviewed as was the Antares rocket motor explosion and Orbital making an agreement to get new RD 181 Russian rocket motors for Antares. Also discussed was Venus Express and recently launched Hayabusa 2 mission. Jeff provided us with updates on all of these missions and companies.

Hello

as mentioned in the show, one major highlight of 2015 will be the survey of Ceres. This celestial body of about 1000 km diameter is not more called an asteroid (as mentioned in the last Hotel Mars show). It is due its size, internal structure and size/roundness a right small (dwarf) planet and falls in same category as Pluto (and as Pluto’s largest moon, which has nearly same size as Ceres). It is believed that Ceres contains more fresh water as the Earth (!), because this dwarf planet is made of about 40% water. It may even exits liquid water layer underneath the outer ice shell, which is covered by dark regolith and dust (which makes it very dark). In my view this event is more important as the Pluto flyby mission, because Ceres has relevance for long term future manned spaceflight (in terms of centuries).

Even Vesta is not more called an asteroid (latest development), because it has internal structure as solar systems rockies planets, Earth, Mars and Venus (iron core and rocky mantel). It is called now a protoplanet by scientists.
