Keeping Voyager Alive: NASA’s Project Scientist Faces Painful Choices as the Iconic Mission Nears Its End #space #engineering #longread
The Voyagers are powered by heat from decaying plutonium, which is converted into electricity. Each year, the aging spacecraft lose about 4 watts of power. In an effort to conserve power, the mission team has turned off any systems that were deemed unnecessary, including a few science instruments. Each Voyager spacecraft began with 10 instruments, but now have just three each. The two spacecraft now have enough power to operate for another year or so before engineers are forced to turn off two more instruments.
The Voyager team, some of whom have worked on the mission since it first began, are forced to make these tough decisions to keep the mission going, in addition to coming up with creative solutions to resolve menacing glitches that affect the spacecraft as they weather the harsh space environment.

How the ‘Guardian’ US Flourishes Without a Paywall #economy #news #internet
“All around us, media organizations have begun to capitulate,” editor Betsy Reed writes in the current fundraising appeal at the bottom of each Guardian article. “The Guardian has neither a self-interested billionaire owner nor profit-seeking corporate henchmen pressuring us to appease the rich and powerful. With the new administration boasting about its desire to punish journalists, and Trump and his allies already pursuing lawsuits against newspapers whose stories they don’t like, it has never been more urgent, or more perilous, to pursue fair, accurate reporting. Can you support The Guardian today?”

Why I Maintain a 17 Year Old Thinkpad | Pilledtexts.com #hardware #sustainability
Old Thinkpads benefits from an open ecosystem. They uses standard PC architecture (x86), so installing various operating systems is easy. On the hardware side, replacement parts are widely available on the secondary market. This broad compatibility keeps the machine relevant long past its original release date. By Taleb’s Lindy Effect, the fact that my T400 can still work well after so many years suggests it’s likely to remain functional as people have already figured out the ways to significantly extend its lifespan.

Rosie the Riveters honored for service in WWII : NPR #history
The symbol has endured.
"Rosie has come to stand for an image of empowerment," says Kimberly Guise, senior curator at the National World War Two Museum. "A symbol of strength and can-do spirit."
Guise says after the war, women were generally forced out of the workforce when service members returned home. But what they did changed the labor landscape.

James Webb Space Telescope Reveals That Most Galaxies Rotate Clockwise | Smithsonian #space #nature
One explanation is that the universe came into existence while in rotation. This theory would support what’s known as black hole cosmology: the hypothesis that our universe exists within a black hole that exists within another parent universe. In other words, black holes create universes within themselves, meaning that the black holes in our own universe also lead to other baby universes.
<...>
Another possible explanation involves the Milky Way’s rotation. Due to an effect called the Doppler shift, astronomers expect galaxies rotating opposite to the Milky Way’s motion to appear brighter, which could explain their overrepresentation in telescopic surveys.
“If that is indeed the case, we will need to re-calibrate our distance measurements for the deep universe,” Shamir explains in the statement. "The re-calibration of distance measurements can also explain several other unsolved questions in cosmology such as the differences in the expansion rates of the universe and the large galaxies that according to the existing distance measurements are expected to be older than the universe itself.”
Open Source Genetic Database Shuts Down to Protect Users From 'Authoritarian Governments' #privacy
The creator of an open source genetic database is shutting it down and deleting all of its data because he has come to believe that its existence is dangerous with “a rise in far-right and other authoritarian governments” in the United States and elsewhere.
“The largest use case for DTC genetic data was not biomedical research or research in big pharma,” Bastian Greshake Tzovaras, the founder of OpenSNP, wrote in a blog post. “Instead, the transformative impact of the data came to fruition among law enforcement agencies, who have put the genealogical properties of genetic data to use.”
