What's missing from this picture on this iPad app's "landing page"? Pluto, Ceres, and Vesta for starters. NASA has missions on their way to these worlds (Dawn and New Horizons). But it does show the ISS (which is not a planet or a moon). Whether you think Pluto, Ceres, and Vesta are planets or dwarf planets or something else, they are the destinations for major missions and deserve to be on this front page. Not to do so is to ignore a billion dollar's worth of hardware and science. I wonder who reviews these apps prior to release? More below.

YouTube: View of the solar system showing the locations of all the asteroids starting in 1980, as asteroids are discovered they are added to the map and highlighted white so you can pick out the new ones. The final colour of an asteroids indicates how closely it comes to the inner solar system. Earth Crossers are Red. Earth Approachers (Perihelion less than 1.3AU) are Yellow. All Others are Green. Notice now the pattern of discovery follows the Earth around its orbit, most discoveries are made in the region directly opposite the Sun. You'll also notice some clusters of discoveries on the line between Earth and Jupiter, these are the result of surveys looking for Jovian moons. Similar clusters of discoveries can be tied to the other outer planets, but those are not visible in this video. More

ESA: Orcus Patera is an enigmatic elliptical depression near Mars's equator, in the eastern hemisphere of the planet. Located between the volcanoes of Elysium Mons and Olympus Mons, its formation remains a mystery. A new image from the High Resolution Stereo Camera aboard ESA's Mars Express orbiter shows the unusual feature with unprecedented clarity.

ESO: Asteroids are often thought of simply as big rocks orbiting the Sun, but they can have quite exciting lives. Small irregularly-shaped asteroids can be "spun up" to fast rotation rates by sunlight falling on them -- much as the asymmetric profile of a propeller blade helps it to spin up in the wind. New results show that when asteroids spin fast enough, they can split into two pieces which then begin orbiting each other. Scientists call this process "rotational fission".

The Cassini spacecraft looks to the cratered surface of Saturn's second largest moon, Rhea. Rhea is 1,528 kilometers, or 949 miles, across. This view looks toward the anti-Saturn side of Rhea. North on Rhea is up and rotated 30 degrees to the right.

The Cassini spacecraft snapped this high-resolution image of Saturn's small moon Epimetheus during the spacecraft's non-targeted flyby on April 7, 2010. The view was obtained at a distance of approximately 107,000 kilometers (66,500 miles) from Epimetheus and at a sun-Epimetheus-spacecraft, or phase, angle of 62 degrees. See Epimetheus Revealed and Epimetheus: Up-Close and Colorful for even closer views.

Opportunity Status for sol 2329-2335: Opportunity again drove five times in the past week, adding more to the total rover odometry as she makes her way to Endeavour crater. The rover drove on Sols 2329, 2330, 2333, 2334 and 2335 (Aug. 12, 13, 16, 17 and 18), totaling over 330 meters (1,083 feet). The rover has been driving with long (about 70 meter, or 230 foot) commanded drives followed by short drive segments of autonomous navigation (AutoNav) to extend the drive distance each sol.

The photos below were sent back to Earth from Mars over the past several days.
