Engineers at NASA say they have successfully revived thrusters aboard Voyager 1, the farthest spacecraft from our planet, in the nick of time before a planned communications blackout.

A side effect of upgrades to an Earth-based antenna that sends commands to Voyager 1 and its twin, Voyager 2, the communications pause could have occurred when the probe faced a critical issue — thruster failure — leaving the space agency without a way to save the historic mission. The new fix to the vehicle’s original roll thrusters, out of action since 2004, could help keep the veteran spacecraft operating until it’s able to contact home again next year.

Voyager 1, launched in September 1977, uses more than one set of thrusters to function properly. Primary thrusters carefully orient the spacecraft so it can keep its antenna pointed at Earth. This ensures that the probe can send back data it collects from its unique perspective 15.5 billion miles (25 billion kilometers) away in interstellar space, as well as receive commands sent by the Voyager team.

That's cool, but forget the thrusters, how is the battery pack on that thing still keeping it powered!?

Good news: I may have a solution to my heating problem. Bad news: it involves me digging up the radioisotope thermoelectric generator. Now, if I remember my training correctly, one of the lessons was titled: "Don't dig up the big box of plutonium, Mark." I get it; RTGs are good for spacecraft, but if they rupture around humans... no more humans, which is why we buried it when we arrived. And planted that flag so we would never be stupid enough to accidentally go near it again. But, as long as I don't break it... [trails off, then starts laughing] I almost just said "Everything will be fine," out loud. Look, the point is, I'm not cold anymore.

Fucking love this book. Funniest thing I've ever read, consistently, from cover to cover

[–] lurker2718@lemmings.world 9 points 2 weeks ago (2 children)

If you haven't read it already, try the new book "Project Hail Mary" also by Andy Weir. I found it even more enthralling.

[–] childOfMagenta@lemm.ee 2 points 2 weeks ago (2 children)

Is it better than Artemis? I found it... Ok. Meh compared to The Martian.

[–] SkaveRat@discuss.tchncs.de 4 points 2 weeks ago

yup. I never finished artemis (but thinking about it, I really should some day). Hail Mary is really really good. Highly recommended.

(also, they are finishing up the movie, which is planned to come out next march)

[–] kfr@sh.itjust.works 4 points 2 weeks ago (1 children)

Yes, Artemis is kinda meh. But Hail Mary is different. I found it better but at least you will find it different.

[–] childOfMagenta@lemm.ee 1 points 2 weeks ago

Thanks, I'll give it a read 😊

[–] GusTheBard@midwest.social 1 points 2 weeks ago

I own the book! It's in the backlog ^-^

I'm currently working my way through the Dune series. I'm nearing the end of book 3 and then I'm going to take a break from Dune to read a few other books. Hail Mary may have to be next up

[–] childOfMagenta@lemm.ee 4 points 2 weeks ago

I think remembering in the book he takes a hot bath with it xD

[–] SkaveRat@discuss.tchncs.de 3 points 2 weeks ago

Look! A pair of boobs! -> (.Y.)

[–] TheLoneMinon@lemm.ee 2 points 2 weeks ago (1 children)

Just finished The Red Rising series and am still feeling spacey, this sounds great. What book is this?

[–] lightnsfw@reddthat.com 12 points 2 weeks ago (1 children)
[–] TheLoneMinon@lemm.ee 5 points 2 weeks ago (3 children)

Ah that makes sense. Thank you! Seen the movie, have not read the book. Gonna give that a go!

[–] Revan343@lemmy.ca 6 points 2 weeks ago (1 children)

That's the quote from the movie itself, unless the book has the same scene word-for-word

[–] SkaveRat@discuss.tchncs.de 4 points 2 weeks ago

just checked, and the book goes into more detail

[–] lightnsfw@reddthat.com 3 points 2 weeks ago

I enjoyed the book.

[–] childOfMagenta@lemm.ee 2 points 2 weeks ago

I read the book before the movie was announced, there is at least a good part missing from the movie.

That book left me longing for more of that same style. Then I picked up the Expanse.

Half life of the plutonium isotope they used is about 88 years.

[–] ContriteErudite@lemmy.world 22 points 2 weeks ago

The spacecraft uses radioisotope thermoelectric generators. It converts the heat generated by radioactive decay of plutonium into electricity. Engineers have been able to keep it working all this time by selectively powering down unused systems.

[–] bitjunkie@lemmy.world 9 points 2 weeks ago

The answer to that is actually really interesting.
