The Falcon 9 DSCOVR’s booster going to hit the Moon: a video — 7 Feb. 2022

The latest on some space debris…
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.

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.

New study probes impact of blackened wind turbine blades
Posted by Shubham Ghosh Roy in category: sustainability
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 is investigating a key Crew Dragon component ahead of Crew-4 flight
Posted by Atanas Atanasov in category: space travel
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.
