China’s plucky Yutu 2 rover is about to wake up and continue to explore the far side of the moon as the nation works to land a rover on Mars this May.

The rover, which launched with the Chang’e 4 mission, landed on the far side of the moon in January 2019 and recently completed its 29th lunar day of activities, the China Lunar Exploration Project (CLEP) said on April 23.

WASHINGTON — A Japanese billionaire best known for buying a SpaceX Starship flight around the moon will go to space first on a Russian Soyuz spacecraft to the International Space Station, two months after a Russian actress and director visit the station.

Space tourism company Space Adventures and the Russian space agency Roscosmos announced May 13 that Yusaku Maezawa will fly to the ISS on the Soyuz MS-20 mission launching Dec. 8 from the Baikonur Cosmodrome. He will be accompanied by a production assistant, Yozo Hirano, on the 12-day flight, commanded by Russian cosmonaut Alexander Misurkin.

“We are excited for Maezawa-san, and we are honored to have enabled this opportunity for him to fly to space,” Eric Anderson, chairman and chief executive of Space Adventures, said in the statement.

They’ve been dubbed “FragAttacks”.

The researcher, Mathy Vanhoef, calls the collection of vulnerabilities “FragAttacks,” with the name being a mashup of “fragmentation” and “aggregation.” He also says the vulnerabilities could be exploited by hackers, allowing them to intercept sensitive data, or show users fake websites, even if they’re using Wi-Fi networks secured with WPA2 or even WPA3. They could also theoretically exploit other devices on your home network.

There are twelve different attack vectors that fall under the classification, which all work in different ways. One exploits routers accepting plaintext during handshakes, one exploits routers caching data in certain types of networks, etc. If you want to read all the technical details on how exactly they work, you can check out Vanhoef’s website.

Particle physics is a field of extremes. Scales always have 10really big number associated. Some results from the Large Hadron Collider Beauty (LHCb) experiment have recently been reported that are statistically significant, and they may have profound implications for the Standard Model, but it might also just be a numbers anomaly, and we won’t get to find out for a while. Let’s dive into the basics of quantum particles, in case your elementary school education is a little rusty.

In the sparse collection of atoms that fills interstellar space, Voyager 1 has measured a long-lasting series of waves where it previously only detected sporadic bursts.

Until recently, every spacecraft in history had made all of its measurements inside our heliosphere, the magnetic bubble inflated by our Sun. But on August 25, 2012, NASA ’s Voyager 1 changed that. As it crossed the heliosphere’s boundary, it became the first human-made object to enter – and measure – interstellar space. Now eight years into its interstellar journey, a close listen of Voyager 1’s data is yielding new insights into what that frontier is like.

If our heliosphere is a ship sailing interstellar waters, Voyager 1 is a life raft just dropped from the deck, determined to survey the currents. For now, any rough waters it feels are mostly from our heliosphere’s wake. But farther out, it will sense the stirrings from sources deeper in the cosmos. Eventually, our heliosphere’s presence will fade from its measurements completely.
