Space aircraft reduced pure samples of Hayabusa2 target asteroids for landing 2031 in the interior of Australia. This aims to restore the second asteroid sample in the world. Where the Hayabusa 1 mission was returned by the Dusty Sample of Asteroid Itokawa in 2010.

The same spaceship is currently on its way to distant areas. This is intended to gather more samples, so that it can help scientists in explaining the history of the origin of the solar system. However, the latest observations about asteroids show that hayabusa2 may be facing difficulties to land in his new target.
Understanding the target asteroids hayabusa2 for landing 2031

Asteroid 1998 KY26 is a small object whose estimated contains about one million gallons of water. This asteroid rotates using high speed, so that one day on the surface of the stone will end almost that fast. It is planned that Hayabusa2 will meet with this asteroid in 2031 and be part of the mission to collect more dust and stone directly from the source.
Through telescope observations around the world, including Very Large Telescope (VLT) in Chile with optimal radar support, it was revealed that the Asteroid size of the Hayabusa2 target for the 2031 landing was only about 10-11 meters (36 feet). Different from the previous estimate which reached 30 meters. Astronomers also managed to collect more data about the new Hayabusa2 target and found that the asteroid size was almost three times smaller.
Even spin faster than the initial estimate. In addition, KY26 rotates at very high speeds, which only takes 5 minutes for one rotation. This is twice shorter than the initial allegations that mention 10 minutes.
“The existence of mini sizes and extreme rotation can make the Hayabusa2 mission more interesting, as well as risky,” said an Eso astronomer, Oliver Hainaut.
Width measurement target
Hayabusa2’s initial target has a width of nearly 3,000 feet or 900 meters. On February 22, 2019, the spacecraft was first successfully landed at Ryugu Asteroid and returned to the second landing around July 2019. Their goal was to take samples from the surface in the crater formed by the first landing.

They did it before finally delivering the sample to the earth. In addition, the Japanese Space Agency has announced the extension of the Hayabusa2 Asteroid Mission for Landing 2031. This is along with the second target that is full of luck.
Traces of Hayabusa’s Success2
The Jaxa Hayabusa2 space vehicle has made history at Ryugu Asteroid in 2020. Where they managed to orbit, land and bring samples back to earth. Currently the new mission awaiting is exploring the small Asteroids of the KY26 in 2031 with plans to orbit, map the surface and the possibility of landing.
The mystery of the KY26 structure
Although the initial data shows that KY26 may be a chunks of solid stones, astronomers still open the possibility that this asteroid is only a pile of fragile debris and has weak gravity.
“At present we have never watched a 10 meter asteroid up close. KY26 is able to surprise the shape and structure,” said Toni Santana-Ros, from Alicante and Barcelona University.
In addition, the researcher hopes that the Hayabusa2 target asteroid for the 2031 landing can be the key in opening the secret whether this asteroid is a solid stone or fragile mound in the space there.
A bigger challenge block
In contrast to the initial target, the second landing of Hayabusa2 will present more complex challenges. Why? Because the size of the asteroid is fairly small and the rotation is fast. The research team involved in this study utilized a large telescope in Europe’s southern observatory along with other instruments. This is to observe KY26 1998 in preparation for the upcoming mission.
“The interesting story here is that we find the size of the asteroid equivalent to the size of the spacecraft that will visit it. We can characterize the small object using a telescope. That is, we can do it for other objects in the future,” said Santana-Ros.
“Our method can have an impact on the asteroid exploration plan to approach the earth in the future or even asteroid mining,” he added again.
This is an interesting fact to wait. Now, just waiting with the enthusiasm of the Asteroid Hayabusa2 Asteroids for the 2031 landing.
The significance of small asteroid research
Small asteroids like KY26 are the most often heavenly objects approaching and hit the earth. Understanding KY26 means recognizing real threats that might fall from the sky.
“Now we realize that dangerous little asteroids can be studied from Earth,” Hainaut added.

Furthermore, the success of the Hayabusa2 target asteroid mission for landing 2031 has the potential to open the way for exploration of space resources. Including minerals and metals which are still a discourse. In addition, the latest findings about Asteroid KY26 which were targeted had appeared on September 18, 2025 at the Nature Communications.
