A week ago Saturday I decided -- against my better judgment -- to tackle this monster of a mosaic. I call it the

Just over a month ago the European Space Agency’s Rosetta spacecraft finished its mission by spectacularly diving into the comet 67P/Churyumov-Gerasimenko. How did it observations influence and alter our ideas about the typical formation and lifetime of a comet?

Opportunity spent the month of October on Spirit Mound studying the rich yet familiar geology at the first science stop on its 10th extended mission – pausing only to take a shot at freeze-framing part of the descent of Europe’s Schiaparelli lander.

Still images of Mars often give a false impression that Mars is a dead planet—but time-lapse imaging from the European Mars Express spacecraft reveals the planet as it really is.

Opportunity is currently finishing up observations of its first outcrop target of its 10th extended mission plan.

At this year’s Division for Planetary Sciences/European Planetary Science Congress meeting, the Exoplanet Dynamics session was packed full of talks on tightly-packed multi-planet systems and their instabilities.

Following up the detection of the Schiaparelli crash site by Mars Reconnaissance Orbiter CTX, the higher-resolution HiRISE camera has now definitively identified the locations of lander impact site, parachute with backshell, and heat shield impact site on the Martian surface.

Last week's Division for Planetary Sciences/European Planetary Science Congress meeting was chock-full of science from New Horizons at Pluto.

Just a day after the arrival of ExoMars Trace Gas Orbiter and its lander Schiaparelli, Mars Reconnaissance Orbiter has taken a photo of the landing site with its Context Camera, and things do not look good.

The fate of the ExoMars lander, Schiaparelli, remains uncertain. European Space Agency mission controllers had been optimistic on Wednesday night that a definitive answer would be known by Thursday morning’s news briefing. However, although some more details have been made public about the lander’s descent, it is not yet clear whether it hit the martian surface at a speed it could not survive.

The third-largest object known beyond Neptune, 2007 OR10, has a moon. The discovery was reported in a poster by Gábor Marton, Csaba Kiss, and Thomas Mueller at the joint meeting of the European Planetary Science Congress and the Division for Planetary Sciences of the American Astronomical Society (DPS/EPSC) on Monday.

Today, the Opportunity rover attempted a difficult, never-before-possible feat: to shoot a photo of an arriving Mars lander from the Martian surface. Unfortunately, that attempt seems not to have succeeded. Opportunity has now returned the images from the observation attempt, but Schiaparelli is not visible.

Trace Gas Orbit is successfully in orbit at Mars, but the fate of the Schiaparelli lander is uncertain.

Pluto’s small moons have unusual rotation rates and states. Now we know a moon of another dwarf planet does as well. Is there a connection?

The Juno mission posted a status report late Friday afternoon, indicating that they will not perform the originally planned period reduction maneuver during their next perijove (closest approach to Jupiter) on October 19. The delay changes the start date of the science mission and also all the future dates of Juno's perijoves.

Schiaparelli is GO for landing, and ExoMars TGO is GO for orbit insertion! When to expect ExoMars events: Schiaparelli separation, final trajectory maneuvers, landing events, orbit insertion, and press briefings.

In the two months since my last Curiosity update, the rover has traversed the scenic Murray Buttes, drilled at Quela, and driven another 300 meters southward.
