We can refuse to accept the status quo of default isolation.

The Falcon 9 DSCOVR’s booster: 7 Feb. 2022.
The animation above comes from 268, single, 4-second exposures, remotely taken with the “Elena” (PlaneWave 17″+Paramount ME+SBIG STL-6303E) robotic unit available at Virtual Telescope. The telescope tracked the apparent motion of the booster, so it looks like a sharp dot, with surrounding stars moving on the background. East is up, South on the left.
There was a VERY strong Moon interference, the booster was in the same spot of the sky as our natural satellite and grabbing it was quite hard. As we can see, the booster is blinking, as it is tumbling with a period of about 90 seconds.
Autonomous, electric vehicles are driving around Yellowstone National Park in a new test program that could become a permanent mode of transportation.
Last week, the park debuted its new “TEDDY” program — or The Electronic Driverless Demonstration in Yellowstone.
“As visitation continues increasing in Yellowstone, we are looking at a range of visitor management actions that focus on protecting resources, improving the visitor experience, and reducing congestion, noise, and pollution,” Superintendent Cam Sholly said in a statement. “Shuttles will unquestionably play a key role in helping achieve these goals in many of the busiest areas of the park.”
Swedish power company Vattenfall has announced plans to embark on further research into whether painting one of the three blades on a wind turbine black can help to reduce the number of bird collisions, with a new three-year study.
Despite stories spread by some media outlets and across social media platforms, wind turbines have been shown to be much less likely to kill birds compared to other man-made obstacles and threats, including coal-fired power plants, as one prime example.
Nevertheless, Vattenfall is seeking to mitigate the impact wind turbines can have on bird populations through a new study in the Dutch seaport of Eemshaven.
SpaceX plans to launch Crew-4 in April.
SpaceX’s human-carrying capsule has a surprise issue with its parachutes. Here’s what it could mean for Crew Dragon Crew-4 and the upcoming Axiom Space mission.
This graph shows the progress in telecommunications bit rates over the last two centuries, and a future extrapolation to the 22nd century.
A primitive form of telecommunications emerged in the late 18th century, when French inventor Claude Chappe demonstrated a practical semaphore system that delivered messages between Paris and Lille. Known as the optical telegraph, it had a transmission rate of two to three symbols (196 different types) each minute, or about 0.4 b/s.
The electrical telegraph, popularised in the 1840s, used a coding system developed by American inventor Samuel Morse, which encoded text characters as sequences of two different signal durations, called dots and dashes. It achieved a rate of approximately 100 b/s.
Tom HlavacSustainable would be a home built of hempcrete, with a greenhouse capable of growing enough food for the family, a small henhouse, and a few bee hives. And a septic system capable of producing fertilizer.
No need for megacorporate involvement. Somethi… See more.
Tom HlavacIf Musk could catalyze adoption of hempcrete and mass produce 3D printers for that, he would do more if value than everything he has done before.

Shinobu Sakamoto was just 15 when she left her home in the southern Japanese fishing village of Minamata to go to Stockholm and tell the world of the horrors of mercury poisoning.
