The H3 rocket is a next-generation rocket developed by JAXA, and this launch will be the 10th. The Mars Satellite Explorer ``MMX'' is a mission to collect samples from Mars' satellites and return to Earth, and the round trip is expected to take about five years.
In the early hours of the 20th, 425 people from inside and outside the prefecture watched the launch of H3 rocket No. 10, carrying the Mars satellite explorer MMX, at Eminoe Observation Park, which is located about 3 kilometers from the launch pad of the Tanegashima Space Center in Kagoshima Prefecture.
Successful space probe launch to Mars satellite, sample collection, round trip in 5 years - "MMX" mounted on H3, JAXA
As the aircraft lifted off with a roar and illuminated the pre-dawn sky, fans with cameras cheered and gazed into the sky.
Toyoko Takeda (59), a part-time worker from Nagoya's Nakagawa Ward, expressed excitement, saying, ``I was moved to be able to witness this historic moment.'' "I feel proud knowing that people all over the world are watching," he said with satisfaction. ``MMX has a lot of missions ahead of it, but I want to tell them to do their best,'' he said, cheering them on.
Shuichi Kikuchi (67), a physician in Tsukuba, Ibaraki Prefecture, who is a big fan of the asteroid explorer Hayabusa, said, ``It's great that the engineers worked so hard to launch it on schedule.I'm looking forward to its return (after collecting samples from the Martian moon).''
Yuri Kamiyama (41), who came from Kashiwa, Chiba Prefecture, to see a rocket launch for her daughter, said it was her first time to see a rocket launch in person. ``I was surprised and moved by the sound and light.My heart is full.'' Daughter Yori (3) exclaimed, ``It was cool. The sound was amazing.''

JAXA launched the Mars Satellite Explorer MMX on H3 rocket No. 10 from the Tanegashima Space Center in Kagoshima Prefecture at 4:41 a.m. on the 20th, and succeeded in inserting it into its planned orbit approximately 1 hour and 11 minutes later. MMX aims to land on the Martian moon Phobos and bring back sand, and plans to make two landings and collect more than 10 grams of sample in 2029. Samples are scheduled to be collected in the Australian desert in 2031.

The probe ``MMX'' aiming for the Martian moon ``Phobos'' will be launched in the early hours of the 20th. In order to prevent contamination by extraterrestrial life and biohazards, it was the first Japanese spacecraft to undergo strict planetary protection measures based on international rules.

JAXA Professor Yuichi Tsuda talked about the MMX spacecraft, which inherits and develops the sample return technology of Hayabusa and Hayabusa2. The MMX, which aims to recover samples from the Mars moon Phobos, is equipped with the world's first technology, emphasizing that it will serve as the basis for interplanetary round-trip flight capabilities. With the launch scheduled for the 20th, we looked back on past difficulties and the real pleasure of exploration.

In the early hours of the 20th, JAXA launched the MMX spacecraft to bring back sand from the Martian moon Phobos. If successful, it will be the first time in the world to land on a Mars satellite, collect samples, and travel to and from Mars. It is also expected to contribute to elucidating the origin of Phobos and to future manned exploration of Mars.
