Taking these 50 facilities from the orbit would reduce the danger of space trash in half
“In your rush to move fast, they add long-term collision hazards,” McKnight said.
Deputy Chief of the Chinese National Space Agency, Bian Zhigang addressed the International Astronautical Congress on Monday. They asked him about the commitment of China to good management space management. Bian admitted a “very serious challenge” in this area, “especially with megaconstelles.” He did not mention the Chinese problem with the leaving rockets in the orbit.
White said China “is currently exploring” how to remove spatial debris from the orbit. One of the mission China claims is to test the techniques of relief for dismissal attached to multiple space boat in orbit, but American officials see it as a military threat. The same basic technologies needed to clean the space for cleaning space, Rendezvous and connecting systems, robotic weapons and automation on board – can be used to laminate the opponents satellite.
Silver lining
McKnight and its co-authors (from the US, Great Britain, Italy, Japan and Russia) went an extra mile to assess the threat of changing the difference to rejecting some of the most dangerous items from the list. He said the results were promising.
“If you take 10 objects, you reduce it by 30 percent,” McKnight said. “It’s a measurable change. I think that’s what’s missing in the past about the justification of active debris.”
Active debris removal is an elusive proposal. Although technically feasible, because several missions showed, there is a question of who pays. Is there a sustainable market for cleaning the space cleaning services? The European Space Agency and the Japanese Space Agency has invested a low level of funding in the debris removal initiatives. One of these projects, led by the Japanese company named Astroscale last year, completed a successful demonstration to set the phase for the future attempt to agree with the defective Japanese rocket and directs him into the atmosphere.
Astroscale was founded in 2013. for the purpose of displacing the low-time orbite of space trash. Realization of a limited market for these missions, the company turned back and back in the continuation of the satellite service and filling fuel technology.
“We can make a measurable impact on the potential that creates debris and potential to start Kessler syndrome by removing 10 or 20 objects,” McKnight said. “The bad news is that we just added 26 new facilities in the last two years.”

Greet the winners of Nobel Prize 2025. Ig
Does alcohol boost Foreign language fluids? Do Western African Lizards have the preferred pizza dressing? And can I paint a cow with zebra stripes help refuse to bite fly? These and other unusual research issues were honored tonight in the virtual ceremony to publish 2025 recipients of the annual Ig Nobel Prize. Yes, again it is the time of the year, when it comes to serious and stupid Converge to science.
Founded in 1991, IG Nobels is a well-intentioned parody of Nobel Prize; They honor “the achievements that first laugh and then make them think.” The solemn campomatic prizes contains miniature operas, scientific demonstrations and lectures 24/7 in which experts must explain their work twice: once in 24 seconds, and others in just seven words.
Speaking for acceptance are limited to 60 seconds. And as the motto implies, research that honors can look ridiculous at first glance, but that doesn’t mean it was deprived of scientific merit. In weeks, after the ceremony, winners will also give free public conversations, which will be published on an amazing internet website.
Without further ADO, here are the winners of the 2025 Ig Nobel Prize.

Quotation: Tomoki Kazato Oishi, Yasushi Matsubara, Yoshihiko Fukushima, Say Sato, Junichi Ueda, and Katsutoshi cinema, for their experiments to find out whether the cows-painted zeba-like cows can avoid being bitten by flies.
Every dairy farmer can tell you that they bite the flies a pesticated plant for the animal herd, which is why one often sees the cows and jerk their skin – desperately trying to enchant themselves. There is an economic cost, because it causes livestock to graze and feed less, a bed for a short time and start pissing together, which increases thermal stress and risk animal injury. This results in a less milk yield for dairy cows and fewer beef yields from the feedlot cattle.
Do you know who doesn’t bite a biting fly? Zebra. Scientists have long discussed the function of a characteristic black and white pattern of zebras. Is that for camouflage? Confusing potential predators? Or is it to reject those boring flies? Tomoki to whom et al. He decided to put the latter hypothesis on the test, paint zebra railroads on the six pregnant women of Japanese black cows in the Aichi agricultural research center in Japan. They used lacquered waters to washed after a few days, so the cows could turn into three different groups: zebra stripes, only black stripes or no strips (as control).
