SLIM(Smart Lander for Investigating Moon)
On January 20, 2024, SLIM will make a pinpoint landing on the moon.
The spacecraft succeeded in photographing the lunar surface (near the SIOLI crater).
The ISAS/SLIM team analyzes the images and sets up a “dog run” on the lunar surface.
SLIM’s solar cells are back in operation:
At 8:04 a.m. on January 29, JAXA tweeted that solar cells were recovering.
SLIM’s solar cells were restored after nine days and were successfully restarted.
Successful observation of “Toy Poodle”:
SLIM and the small robot SORA-Q successfully observed a “toy poodle.”
Images taken with a multiband spectroscopic camera were transmitted to Earth.

Naming a rock on the moon with a dog breed name:
Six rocks are visible in the lunar surface photograph taken by SLIM.
Each one was given the name “dog.”
Saint Bernard, Kai Inu, Akita Inu, Bulldog, Shiba Inu, Toy Poodle.
Reason for setting “dog breed name on rock”:
Rather than calling them ‘Rock A’ and ‘Rock B’, it is easier to understand ‘Toy Poodle’.
After SLIM is recovered, each rock will be photographed using a multiband spectroscopic camera.
SLIM research mission:
We will use a multiband spectroscopic camera to examine rocks in detail to learn about the formation of the moon.
The surface of the moon is 37.93 million square kilometers, which is 100 times the area of Japan (378,000 square kilometers).
SLIM team’s lunar survey:
The SLIM team analyzed vast amounts of detailed images of the lunar surface from the past.
1. Survey results of Japan’s lunar probe “Kaguya” (2007)
2. Survey results of the American lunar probe “LRO”
As a result of image analysis, a very narrow point on the moon was selected for investigation.
This time, rock composition and detection data from points on the moon will be transmitted to Earth.
Details of unexpected trouble:
On January 25th, details of the trouble and results were announced.
He explained the unbelievable accident with detailed data.
At 12:19am on January 20th, hovering at an altitude of 50m.
The nozzle part of the main engine fell off.
It may have been an impact from a micrometeorite (asteroid fragment).
20,000 meteorites fall on Earth every year.
Activities on the moon are life-threatening:
On Earth, most meteorites burn up in the atmosphere.
However, the moon has no atmosphere, so it will never burn out.
Therefore, some people say that human activities on the moon are risking our lives.
“Hayabusa” also experienced:
Hayabusa’s solar panels were damaged.
The arrival of the asteroid Itokawa has been delayed by three months.
It appears that Hayabusa’s troubles were caused by this solar flare.
Super mini robot in action:
Super mini robot LEV-2 (SORA-Q):
The separated ultra-mini robot LEV-2 took a photo of SLIM in a handstand position.
LEV-2 (SORA-Q) and LEV-1:
1. SLIM separates LEV-1 (2.1 kg) and LEV-2 (250 g) at an altitude of 5 m.
2. LEV-2 and LEV-1 move and establish mutual communication (Bluetooth communication).
3. LEV-2 photographs the SLIM, automatically selects the image, and sends it to LEV-1.
LEV-1 continued to transmit data including this directly to Earth (a world first)
SLIM captures the entire dog run area
SLIM has not received sunlight since landing.
1. SLIM photographed the “dog run” area in advance with a multi-spectral camera.
2. By the time it descended, it had transmitted detailed data to Earth and went to sleep.
The research team set up a “lunar dog run” based on the photos received by SLIM.
Shocking lunar exploration activities around the world:
Researchers around the world are currently competing in a race to explore the moon.
Researchers must have been shocked by the results of SLIM.
We have no choice but to review our moon landing strategy, pinpoint technology, etc.
The importance of pinpoint landing
1. The technology of ‘landing where you can’ is already outdated.
2. A probe that cannot land where it wants to land loses its value.
Successful observation of toy poodle:
SLIM withstood a temperature difference of nearly 300 degrees between day and night for three days.
Then I woke up to the sunlight.
Investigating the rock composition of “Toy Poodle”, which is the closest to SLIM.
A multi-spectroscopic camera was used to observe 10 bands of wavelengths and transmit them to Earth.
