TOKYO—Japanese space agency scientists said Thursday they plan to bring soil samples back from the Mars region ahead of the United States and China, which started Mars missions last year, in hopes of finding clues to the planet’s origin and traces of possible life.
The Japan Aerospace Exploration Agency, or JAXA, plans to launch an explorer in 2024 to land on Phobos, a Martian moon, to collect 10 grams (0.35 ounce) of soil and bring it back to Earth in 2029.
