Rules:

Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

12.3 Billion Miles Away: NASA Has Lost Communication With Voyager 2 Spacecraft (scitechdaily.com)

NASA’s Voyager 2 has lost communication with Earth due to an unintentional shift in its antenna direction. The next programmed orientation adjustment on October 15 is expected to restore communication, while Voyager 1 continues to operate as usual.

A series of scheduled commands directed at NASA’s Voyager 2 spacecraft on July 21 led to an unintentional change in antenna direction. Consequently, the antenna moved 2 degrees off course from Earth, causing the spacecraft to lose its ability to receive commands or transmit data back to our planet.

Precision for what? Knowing their cron job will fire? Knowing what was wrong with the commands they sent? Neither of those are crazy precise or ambiguous statements?

The only highly precise thing that needs to happen is the alignment of the antenna but that system has been working for decades already and has been thoroughly tested.

NASA tends to be pretty straightforward when talking about risks, and if they feel like all the systems are in working order and there's a good chance we'll be back in contact with it, I think it's worth talking them at their word.

Like yeah, it's impressive they can aim an antenna that precisely, but using stars to orient an object is a very very well understood geometry problem. NASA has been using that technique at least as far back as Apollo

When was the last time the maneuvering jets were fired off? Especially so in the crafts current condition of it being in a very low power mode? They may know the craft and its design well but they're not there seeing the craft in its current condition to know if things will work as they would want them to.

There's a million things that can go wrong that they're not aware of, his original comment is actually correct and not worthy the attack it's getting. There's always the unknown when you're working with hardware and software, especially in deep space.
