These Tiny Disks Could Explore the ‘Ignorosphere’ That Planes and Satellites Can’t Reach With no fuel or engines, tiny explorers will surf sun-warmed air alone to explore high in the skies of Earth and Mars

With no fuel or engines, tiny explorers will surf sun-warmed air alone to explore high in the skies of Earth and Mars

These tiny flyers levitate on the Sun’s heat alone Design could help to probe the ‘ignorosphere’, a layer of ultra-thin air that has largely escaped exploration by balloons, aircraft and satellites.

Tiny discs can levitate in the upper atmosphere using sunlight alone A physics phenomenon discovered 150 years ago allows tiny objects to levitate using just sunlight – and now it could enable swarms of sensors to explore part of Earth’s long-neglected upper atmosphere

Imagine if Joe Biden had reposted a liberal pundit saying ‘shut up about gas prices’ in 2022. It would have led the news, all of the news, for days, weeks, on end.

Without evidence, Trump blames FAA diversity initiatives for the crash

After a moment of silence, Trump started his remarks by saying that America is grieving for the lives lost.

"We are one family today and we are all heartbroken," he said. He then went on to say that diversity initiatives at the FAA compromised the standards for air traffic controllers.

Why/how would any travel visa prohibit someone from legally working in their home country? They stopped travelers from using Zoom? DN's dump money into the host country without taking jobs or benefits. A visa rule saying you're not allowed to have a legal job in your home country sounds insane.

If the consumers who don't need to be on there bail, there's no reason for businesses to be there. You vote with your dollar and your time, every single day. A vote is a vote no matter the reason.

International Criminal Court seeks warrants for Taliban leaders for gender-based crimes | CNN The International Criminal Court (ICC) is seeking arrest warrants for Taliban leaders for alleged gender-based crimes, as the group continues to crack down on women’s rights in Afghanistan.

Trump grants sweeping pardon of Jan. 6 defendants, including rioters who violently attacked police President Donald Trump has pardoned, commuted the prison sentences or vowed to dismiss the cases of all of the 1,500-plus people charged with crimes in the Jan. 6, 2021, attack on the U.S.

Tough on crime they said. Blue lives matter they said.
