Still making tracks and doing science! Since breaking the all-time off-world driving distance record on Oct. 11, Perseverance has continued work on the Red Planet.  ½

Perseverance has set a new off-world record! 🏅 On Oct. 11, the rover's odometer hit 28.10 miles (45.22 kilometers), eclipsing the distance record set by NASA's Opportunity rover. 1/2

The MMX spacecraft carries two pieces of NASA hardware: The MEGANE instrument will be key to revealing the origin of Mars’s moons by measuring their elemental composition. The P-Sampler demonstration will advance capabilities for surface material acquisition in low gravity. ½

Congrats to @JAXA_En on MMX! By returning samples from Phobos, Mars’ larger moon, the mission will add to decades of Mars exploration and help shape future discoveries and potential crewed missions to the Red Planet.

We've studied the moons of Mars from Earth, from orbit, and even in the sky as seen from the surface. (This view comes from the Curiosity rover.) Now, the @JAXA_en MMX mission will see them up close, and even bring a sample home. NASA will be assisting each step of the way. 1/2

Today, @JAXA_en is scheduled to launch its Martian Moons eXploration (MMX) mission. Aboard is MEGANE, an instrument built by Johns Hopkins APL for @NASA that will study Phobos' elemental composition to help uncover the origins of Mars' moons.
Today, JAXA is scheduled to launch the Martian Moons eXploration (MMX) mission from Japan. With an instrument built by Johns Hopkins APL for NASA aboard, MMX will investigate whether Mars' moons formed from debris following an impact on Mars or are asteroids captured by its gravity.

Built by Johns Hopkins APL on behalf of NASA, MEGANE is a neutron and gamma-ray spectrometer that will study Phobos, the larger of Mars' two moons. By measuring neutrons and gamma rays emitted from its surface, MEGANE will help scientists determine which elements make up the moon.

As MMX makes repeated passes over Phobos, MEGANE will collect measurements that scientists can use to map the moon’s elemental composition. This illustration shows what a map of Phobos’ elemental composition could look like based on MEGANE’s future measurements. These maps could provide important clues about how Phobos formed.
