NASA’s Voyager 1 spacecraft has experienced a computer glitch that’s causing a bit of a communication breakdown between the 46-year-old probe and its mission team on Earth.

For those who didn’t read the article, voyager 1 is still sending and transmitting data. It’s stuck in a loop sending the same packets to Earth on repeat but it is receiving commands just fine. It’s not completely dark.

That's fantastic, that means all they have to do is reset some components and it should restore functionality. I say should, it's still a scary thing to turn on/off components om a satellite bcz you aren't guaranteed they'll come on. Nasa people usually prefer soft resets to hard resets of components, but we'll see what happens.

One of the satellites I worked on had to have a software update to do a soft reset of a component every time it tried to write certain data. It was really scary bcz we thought we had lost one of our redundancies right after launch, which would have sucked.

But, we didn't. Anyway, just wanted to give a little bit of insight into what the FOT might be thinking about while they're trying to recover the satellite to nominal state.

Yeah I got very sad when I saw the headline and breathed a huge sigh of relief. Voyager 1’s death will be far sadder than most public figures. Maybe any.

[–] NocturnalMorning@lemmy.world 33 points 9 months ago (1 children)

Same, for a moment I was really concerned. Voyager is like a lifetime achievement for humanity at this point. When it stops communicating its going to be a big loss for the scientific community, and population as a whole. I'm not looking forward to hearing about its loss of functionality in the next decade or so.

[–] postmateDumbass@lemmy.world 1 points 9 months ago (2 children)

Will we ever reach as far again?

[–] Meowoem@sh.itjust.works 2 points 9 months ago

I think when we have space based fuel and fabrication infrastructure we'll be able to make some interesting projects, some huge thing that just burns its rockets at full power through the solar system.

Or a very robust probe fired from a giant nuclear cannon on the dark side of the moon. If you start the journey at top speed that cuts out all the acceleration time, we could have stuff popping off in every direction.

[–] NocturnalMorning@lemmy.world 2 points 9 months ago (1 children)

I really can't say, I'm not privy to any of the outer solar system projects that might be in the works. Voyager was originally intended to do flyby of the outer planets, and then it headed out of the solar system. I think the trajectory was always designed with the idea that it could exit the solar system. As far as I'm aware, we've done a few missions to asteroids, but nothing that is going out to do flyby of the outer planets. But, I could be wrong, don't take my word for it. All of the stuff I have worked on has been near earth, or pointing away from the earth but still within the vicinity of L1 and L2 Lagrange points.

You'd be surprised how many missions nasa has in the works at any one time.

From ChatGPT just now:

Me: Summarize projects active as of early 2022 involving plans to send objects out of the solar system

ChatGPT (v4) Voyager 1 and 2: Continuing their journey, both launched in the 1970s. They are studying the outer solar system and interstellar space. New Horizons: After its Pluto flyby, it's on an extended mission to explore the Kuiper Belt and beyond.

Pioneer 10 and 11: Although no longer sending data, they continue to travel out of the solar system.

Interstellar Probe Study: A NASA conceptual study for a mission to explore the interstellar medium.

Breakthrough Starshot Initiative: A research and engineering project aiming to develop a proof-of-concept fleet of light sail spacecraft, capable of making the journey to Alpha Centauri.

NASA Innovative Advanced Concepts (NIAC) Programs: Some concepts under study, such as solar sails and fusion propulsion, could potentially send craft out of the solar system. These projects represent a blend of ongoing missions, conceptual studies, and advanced propulsion research with potential applications for future interstellar travel.

[–] intensely_human@lemm.ee 1 points 9 months ago

Incidentally, the light sail starshot project is talking about speeds of 0.3c.

I fucking love that project. Heard about it from Neil Tyson.

[–] deweydecibel@lemmy.world 20 points 9 months ago (2 children)

Wait till it returns as V'ger

[–] TheRealKuni@lemmy.world 3 points 9 months ago

Or the Mighty V-GINY.

[–] BearOfaTime@lemm.ee 0 points 9 months ago

You waited 40 years to be able to use that.

Hats off to you.

[–] gazter@aussie.zone 10 points 9 months ago

I don't know if I would consider Voyager to be 'dead' if it stops transmitting.

If I put a message in a bottle, with a blinky light on it, then throw it into the ocean, the message is still there even if the blinky light goes out.

So the title did its job which is you understand nothing until you enter their site, drive traffic, display ads, and possibly collect your data in the process.

[–] originalfrozenbanana@lemm.ee 25 points 9 months ago

Sure and Lemmy did its work by letting me and others relay the info. I hate ads as much as the next guy, especially targeted ads, but the internet is free and I don’t pay CNN a dime so I’ll take the hit for you this time. Next time, you click the clickbait and fill us in ☺️

[–] postmateDumbass@lemmy.world 26 points 9 months ago (1 children)

Are we sure it isn't YouTube trying to insert an ad?

[–] RazorsLedge@lemmy.world 8 points 9 months ago

This is the dumbest thing I've read today. You got a giggle out of me.

[–] Karyoplasma@discuss.tchncs.de 6 points 9 months ago (2 children)

How do we know that it's receiving commands fine? I am assuming pinging Voyager 1 might take a while.

[–] intensely_human@lemm.ee 4 points 9 months ago

It takes 45 hours and that’s a good question.

Perhaps there are multiple distinct channels with one for command responses and another for scientific data?

[–] duplexsystem@lemmy.blahaj.zone 1 points 9 months ago

It takes 20+ hours so since the announcement and now they could have send a command and gotten a response

[–] MeanEYE@lemmy.world 5 points 9 months ago (2 children)

Ideally it was an update issue and it's fixable. However I wouldn't be surprised if there was a hardware failure due to radiation or something similar. That said, Voyager1 has power only until 2025 or so, since RTGs are designed to last that much. So even if the issue is fixed, its life will only expand by few years. Also, the fact it relies on nuclear power means none of the new stuff will last as long since they stopped using them some time ago due to fear from nuclear energy.

[–] postmateDumbass@lemmy.world 2 points 9 months ago (1 children)

God forbid we pollute the far reaches of space with radiation. (sic.)

[–] MeanEYE@lemmy.world 3 points 9 months ago (2 children)

Am thinking people were mostly worried if rocket explodes during liftoff. Then again people also are completely clueless about radiation in general, especially smokers.

[–] MrShankles@reddthat.com 3 points 9 months ago (1 children)

As a smoker: I'm not clueless, I just don't love myself more than the addiction. But I'm getting there, cause breathing "easily" is an under-rated pleasure, when compared to... not breathing that well

It can take time to break the mental stuff before breaking the habit, regardless of understood risk

Now magnets though... I'm at a complete fucking loss

[–] MeanEYE@lemmy.world 0 points 9 months ago

My point is that not many people know that tobacco contains lead-210 and polonium-210. This is why waping is safer, even though it still carries health risks it doesn't have radioactive elements which deposit in your lungs. And it's not a negligible amount of radiation. You'd be safer living next to Chernobyl plant before it was contained than smoking a pack a day. Do yourself a favor and switch to electronic stuff.

[–] Meowoem@sh.itjust.works -1 points 9 months ago

One of the main people who raised concern about rockets full of nuclear material exploding above populated areas was mitchio kaku. He certainly has a good few clues about radiation and nuclear physics.

[–] elbrar@pawb.social 1 points 9 months ago (1 children)

RTGs are still used for outer solar system missions. Not enough light for solar panels. Hell, even the Perseverance Mars rover, which was launched in 2020, has an RTG.

[–] MeanEYE@lemmy.world 1 points 9 months ago

Hm, didn't know about those. Good to hear. RTGs are such a great technology.

[–] doctorcrimson@lemmy.today 1 points 9 months ago

I wonder if it's struggling with Parity Checks?
