We now know the science goals for NASA’s next major Mars mission. The new rover will further the astrobiological search begun by the Curiosity rover and store samples for eventual return to the Earth, providing a stepping stone to the next stage of Martian exploration.
We are now only about 180 meters from the new mountain, Solander Point. We slowed down this week so that we could check out the rocks here where there is a strange hydration signature from orbital remote sensing.
The International Association of Geomorphologists' "planetary geomorphology image of the month," contributed by Joe Levy, features water tracks on Earth and compares them to recurring slope lineae on Mars.
The fictional world Tatooine, scene of action in the Star Wars movies, is named after a town in Tunisia, where parts of the movies were filmed. The desert backdrops against which the movies were filmed are real terrestrial landscapes, which prove to be perhaps unexpectedly dynamic.
It had never occurred to me to think about geostationary satellites in Mars orbit before reading a new paper by Juan Silva and Pilar Romero. The paper shows that it takes a lot more work to maintain a stationary orbit at an arbitrary longitude at Mars than it does at Earth.
