NASA's interstellar Voyager probes get software updates beamed from 12 billion miles away::A few updates to the two Voyager spacecraft should extend the space explorers' lives so they can continue adventuring in the cosmos.

It's mind blowing that we launched something over 45 years ago and it hasn't traveled one light day yet.

Mooooom! 32GiB of RAM isnt' enough for me to code a decent app!

I don’t even have a normal WiFi signal and these mofos update a satellite 12 billion miles away.

This is the best summary I could come up with:


"This far into the mission, the engineering team is being faced with a lot of challenges for which we just don’t have a playbook."

One update, a software fix, ought to tend to the corrupted data that Voyager 1 began transmitting last year, and another set aims to prevent gunk from building up in both spacecraft's thrusters.

This bugfix won't answer why the AACS had diverted the telemetry data in the first place, however, a mystery that may hint at a larger problem with Voyager 1.

Still, engineers are confident the patch should stem the issue — at least, after the update’s transmission completes its more-than-20-hour-long journey to Voyager 1.

Over decades of maneuvers, the residue has built up; engineers worry that the tubes might soon clog completely.

So, over September and October, engineers began allowing the spacecraft to rotate more— aiming to reduce how often the probes need to fire.

Interesting fact is voyager both 1 & 2 using less than 1 mega byte of ram

[–] bstix@feddit.dk 24 points 2 years ago

Much less than 1mb. Something like 69 kB.

The ram only holds the programs which are written in Fortran and assembly. The images and other data are stored on tape.

Another interesting fact is that the computer holds the record for being the longest running computer of all time.

And 270w of power as of 2011, dropping exponentially over time

[–] poopkins@lemmy.world 7 points 2 years ago

249W as of today. I'm hoping for some kind of miracle to get it to the 50-year mark.

Imagine if it were running Windows - probably faster to send a Starship full of floppies

Don't let this distract you from the fact there are more devices on Mars with working sound than there are on Earth

[–] RedEyeFlightControl@lemmy.world 3 points 2 years ago

There are more planes in the ocean than there are submarines in the sky, too.
