In 2018, Hibosa 2 missions successfully faced Raigo Rigo. Japan Aerospace Explorus Agency (Jaxa) arrived at the spacecraft, touched it, gathered its samples, and turned away from Teena. He returned the samples to the ground in 2020.
There is plenty of fuel left for its expansion mission, called Hibosa 2# or “Hibosa 2 Sharp”, the spacecraft departed towards its next purpose, in 2026, 98943 Torifone fast flying.26 In 2031.
But this ultimate goal can be much more difficult than the concept initially. Observations based on the new Ground of 199826 It has been revealed that the teens are 3 times smaller than the previous thinking and rotates twice at a speed.
“We have found that the reality of this item is quite different from what was mentioned earlier,” Tony Santana Russia, the main author of a new research on Wii of 1998, 199826 And a researcher at the University of D -Delikanta in Spain and a researcher at the University of D Barcelona said in a statement.
Small and sharp
Astronomers discovered the 1998 Wi26 In 1998, when it came within 2 times the distance of the Earth’s moon. Immediately after the discovery, the radar and visual observations estimated that Kishodarra was about 30 meters away and roams once every 10.7 minutes, the fastest rotating tear. As soon as Kishodar went, it became unconscious to see for more than 2 decades. When the mission scientists of Hibosa 2 chose goals for their expansion mission, they relied on these 1998 accounts.
Kishodarra completes a spin every 5 minutes and 21 seconds, which takes less time to listen to the Queen’s “Bohemine Rapidi”.
Finally, in 2024, 199826 Once again, the ground came close to observation. Using the most powerful ground-based telescopes available, Santana-Ros and his colleagues saw the thunderstorms and rotation of the nasty teens from multiple angles, which could calculate the more accurate spin rate than a limited radar and photometry in 1998.
He calculated that Kishodarra completed a spin every 5 minutes and 21 seconds, which takes less time to hear the Queen’s “Bohemine Rapidi”. The team then mixed these new observations with the 1998 radar data to re -count the size of the Teenagra. They found that instead of being about 30 meters in Qatar, of 199826 Only about 11 meters, or about the length of the telephone pole. The team published these results Nature communications September 18.
“The smaller teens you will find, the more abundant, the more abundant,” said Teddy Cricket, a scientist at the University of Vilanova, Pennsylvania. “The fact that this new paper gets such a small size for KY26 This is very interesting itself – Hybosa 2 will be able to find a highly underdeveloped population – but that also means that we too may not have a huge number of unknown items to compare. “
A challenge and a chance
The new size and spin measure of 1998 KY26 Researchers wrote that Hibosa 2’s planned touchdown would make it more difficult. However, this is not the first time that a teenager Randizos Mission had to adjust its expectations to the middle flight. Both Riogo and Beno, the beginning of NASA, the interpretation of the NASA, the resource identification, the first target of the Osiris-Rex Mission (Osiris-Rex) missions, were at a higher levels than expected, in which related missions need to adjust their samples to accumulate ways. Also, the Osarers Rex team learned that Beno was only actively spitting the material when the spacecraft approached, causing it to change its plan to enter the orbit.
In spite of new challenges with 1998 KY26Hibosa 2#team has a great advantage: 6 years to work again.
“The Hibosa 2 team is incredibly smart, diligent, and has a ton of experience under their belts, but I believe that such a result is a bit of a handful of hands and anxiety even if the spacecraft is fully capable,” said Cricket.
“We have never seen a ten -meter -sized teens in the situation, so we don’t really know what to expect and how it will look.”
“I am sure that even the team is skeptical about whether the actual plan was possible or not, but if I had to bet the money, I still think the team will try. [to touch down]”He added.” You set yourself up by making a huge spacecraft and a great team of engineers and scientists for its staff collecting success, but whenever you try to do something new, this is still a prerequisite. “
Even if the touchdown on the 1998 KY26 Ultimately it is impossible and Hibosa 2# just flies, scientists from Kentarrah will still get valuable information about incredibly common but hardly smaller.
Santana Russia wrote, “We have never seen a ten -meter -sized Kent in the situation, so we do not really know what to expect and how it will look.”
“In many ways, its spacecraft is now more interesting than ever before,” said Carita.
