Opportunity spent a mostly merry month of May on Mars touring Spirit of St. Louis Crater, stopping at science targets named in honor of Charles Lindbergh and the incredible flight he took 88 years ago.

Pause your life for six minutes and watch the Sun set....on Mars. Thank you, Glen Nagle, for this awe-inspiring simulation based on Curiosity's sol 956 sunset images.

In the last two months, there has been significant news about the European-Russian 2018 mission and about NASA’s 2020 rover. NASA also has announced that it would like to send a new orbiter to the Red Planet in the early 2020s.

Curiosity is finally on the road again! And she's never taken a more scenic route than this. Her path to Mount Sharp is taking her to the west and south, across sandy swales between rocky rises.

Long before Curiosity's landing, the description of the color camera made ​​me dream: I imagined what wonderful pictures we could get of sunsets and sunrises on Mars. They finally came on sol 956, the 15th of April, 2015.

After investigating some flat, light and dark toned rocks around Spirit of St. Louis Crater in April, Opportunity chalked up another milestone achievement – the 4000th sol or Martian day of surface operations.

MER mission ops team members joined other engineers and scientists, some who previously worked on the MER mission, to take on the challenge of a relay marathon to celebrate Opportunity's milestone achievement.

Since I last wrote about Curiosity drilling at Pink Cliffs, the rover has visited and studied two major sites, drilling at one of them. It has also suffered a short in the drill percussion mechanism that presents serious enough risk to warrant a moratorium on drill use until engineers develop a plan to continue to operate it safely.

On March 24, 2015, after spending several weeks investigating some new rock types along the western rim of Endeavour Crater, Opportunity roved past 42.2 kilometers (26.2 miles) and put the first off-Earth marathon in her rear view mirror, driving the Mars Exploration Rovers mission back into the space history books.

The NASA Administrator declared that the Opportunity rover is a mission 'whose time has passed' and will be defunded next year. Will Congress act to save it?

In pictures of the planets, the stars aren't usually visible. But when they do appear, they're spectacular.

From the discovery of a new rock type to a successful flight software upload that should enable the robot field geologist to regain her long-term, flash memory, Opportunity and her team delivered what turned out to be a hugely productive and memorable 133rd month on the Red Planet.
