OUTLINE:
The new data also confirms that Texas has cemented its position as the crypto capital of the United States, as miners flock there for abundant clean energy and a permissive regulatory environment.
Texas made up 8.43% of the hashrate in the U.S. as of the end of 2021, and that percentage has jumped to 28.50% as of July 27, 2023 — though Foundry notes that the data was aggregated during a period of heavy curtailment in July, so Texas’s percentage of actual hashrate is even greater than what’s reflected on their latest map. Zhang added that Texas’s growth in Foundry’s map also had to do with the fact that the firm took on more clients there in the past two years.
Given that the U.S. is currently the world leader in terms of its share of the collective hashrate of the bitcoin network, that makes Texas the bitcoin capital of the world.

The cosmos seem silent and empty of any great interstellar empires, but perhaps they once existed, and if so, what titanic ruins might they have left behind?

In the morning hours of Sept. 24, a small capsule containing surface samples from asteroid 101,955 Bennu careened into Earth’s atmosphere after a seven-year journey through space. The landing of this sample capsule is the culmination of NASA’s historic Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) asteroid sample return mission, which is now the first American mission to return samples from an asteroid.
The sample return capsule (SRC) landed within a 14 by 58-kilometer ellipse at a Department of Defense property at the Utah Test and Training Range and Dugway Proving Ground in Utah. Touchdown of the SRC occurred at 8:52 AM MDT (14:52 UTC) — three minutes earlier than planned. Low winds and dry weather was present at Dugway during the landing — optimal conditions for the return and recovery of the SRC.
OSIRIS-REx launched atop a United Launch Alliance Atlas V rocket on Sept. 8, 2016. Since then, OSIRIS-REx has flown past Earth, rendezvoused with asteroid 101,955 Bennu, orbited the asteroid and extensively imaged/mapped its surface, collected a sample from Bennu, made the journey back to Earth, and now returned its sample. As the SRC was streaking through Earth’s atmosphere, OSIRIS-REx performed a flyby of Earth and began a new mission called OSIRIS-APEX, wherein OSIRIS-REx will fly out and study asteroid 99,942 Apophis. The spacecraft is scheduled to arrive at the asteroid in 2029 if all goes according to plan.

Planet Earth is about to receive a special delivery—the biggest sample yet from an asteroid.
A NASA spacecraft will fly by Earth on Sunday and drop off what is expected to be at least a cupful of rubble it grabbed from the asteroid Bennu, closing out a seven-year quest.
The sample capsule will parachute into the Utah desert as its mothership, the Osiris-Rex spacecraft, zooms off for an encounter with another asteroid.
Our current theory of evolution holds that all life on Earth originated from a single, simple life form billions of years ago. But what if that life did not originate on Earth? In this episode we’ll explore the theory of Panspermia, that origin of life might be extraterrestrial in origin, and that the abiogenesis of that origin life form we descend from might have descended from the sky in a comet or some other alien source. We will explore the impact this concept would have on the Fermi Paradox if true.

NASA is edging closer to the conclusion of its ambitious seven-year mission, aiming to prevent a catastrophic collision of a massive asteroid named Bennu with Earth. Recent findings have indicated that there’s a 1 in 2,700 chance of Bennu slamming into Earth on September 24, 2182.
Roughly the size of the iconic Empire State Building, Bennu spans about a third of a mile wide. The potential aftermath of its predicted collision with Earth could equate to the explosive energy of 22 atomic bombs.
The asteroid makes its presence felt by passing Earth approximately every six years. However, scientists anticipate that its most perilous close encounter could be a mere 159 years away.
