For 17 hours on 3 October, the Mobile Asteroid Surface Scout (MASCOT) lander sent data to the waiting Hayabusa2 orbiter from multiple locations on Ryugu.

As the global storm that wrapped the Red Planet in a cloud of dust since late June finally gave up the ghost in September, the sky continued to clear over Endeavour Crater and the Opportunity team initiated the NASA-approved two-step plan to reestablish contact with the rover.

The two small spacecraft are the size and shape of cheese wheels, and can autonomously hop around the surface.

On Jan. 1, NASA's New Horizons will perform a high-risk, high-reward flyby of an ancient world on the outskirts of the solar system.

With my first issue of The Planetary Report as editor, I am taking the magazine open-access. Return to Mercury features articles by Elsa Montagnon on BepiColombo and by Long Xiao on the Chang'e-4 and -5 landers.

Elsa Montagnon details the challenges of delivering BepiColombo’s two spacecraft from Earth to Mercury.

Long Xiao

Long Xiao previews two ambitious Chinese lunar missions, one of which will make the first-ever landing on the far side of the Moon.

Hayabusa2 didn’t quite make it down to its intended 60-meter distance from asteroid Ryugu yesterday. There is nothing wrong with the spacecraft; it’s healthy and returning to its home position. The team will adjust parameters and give it another try in the future.

The dust raising power of the storms that wrapped Mars in a cloud in June and July diminished in August. Meanwhile, on Earth, the Opportunity team at NASA’s Jet Propulsion Laboratory reviewed recovery plans, conducted additional simulations, and began wrapping the month with newfound reasons to believe Opportunity can emerge from her hibernation.

Heedless of the (now-dissipating) dust storm, Curiosity has achieved its first successful drill into rocks that form the Vera Rubin ridge, and is hopefully on the way to a second. It took three attempts for Curiosity to find a soft enough spot, with Voyageurs and Ailsa Craig being too tough, but Stoer proved obligingly soft on sol 2136.

Like its human colleagues, Dawn started out on Earth, but now its permanent residence in the solar system, Ceres, is far, far away. Let's bring this cosmic landscape into perspective.

A fantastic story of adventure, exploration and discovery is reaching its denouement. In the final phase of its long and productive deep-space mission, Dawn is operating flawlessly in orbit around dwarf planet Ceres.

Both OSIRIS-REx and New Horizons achieved first light on their still-distant targets this week. Between now and the end of 2018, Bennu and 2014 MU69 will turn from points of light into places.

Two months after arrival, the team has reported some preliminary facts about Ryugu. They also announced the selection of candidate landing sites for the spacecraft sample collection, for the German-built MASCOT hopper, and for the MINERVA-II microrovers

It was a signal from the Mars Reconnaissance Orbiter, not Opportunity, that showed up on a Deep Space Network dashboard last week.

Though progress is being made on Mars Sample Return, a new report from the National Academies recommends NASA have a long-term plan for robotic Mars exploration, and work to ensure communications infrastructure is maintained at the Red Planet. These recommendations largely align with those made by The Planetary Society in a report released in 2017.
