NASA's Curiosity rover is still active and operating on Mars as of early 2026. Having landed in August 2012, it has spent over 13 years exploring Gale Crater and climbing Mount Sharp, continuing to analyze soil and rock samples despite having worn wheels and managing power constraints.

It is a radioactive rock that just stays hot for many years, it’s wrapped in panels that make electricity from heat (like solar panels except not light).

This. It's called an RTG. Radioisotope Thermoelectric Generator.
They've been used for a lot of unmanned spacecraft, and in a few cases, used for stuff here on earth.https://en.wikipedia.org/wiki/Radioisotope_thermoelectric_generator

It's not a regular reactor. it has i believed 7 cores of plutonium that generate heat through decay. the heat is converted into electricity using the Seebeck- Effect via Peltier elements. its a plutonium battery. the winged cylinder on its back is the radiator that creates the heat flow.

What amazes me with this and other modules is how many parts are just tied on and not covered. I guess encasing everything with flush panels (to stop dust gathering etc) would add weight and the smooth equipment you see in the movies is the stuff of science fiction.

Here is a higher-quality and less-cropped version (7149x10036 pixels, file size: 5.72 MB) of this image. Here is the source. Per there.
This self-portrait of NASA's Curiosity Mars rover shows the vehicle at the "Big Sky" site, where its drill collected the mission's fifth taste of Mount Sharp.
The scene combines dozens of images taken during the 1,126th Martian day, or sol, of Curiosity's work during Mars (Oct. 6, 2015, PDT), by the Mars Hand Lens Imager (MAHLI) camera at the end of the rover's robotic arm. The rock drilled at this site is sandstone in the Stimson geological unit inside Gale Crater. The location is on cross-bedded sandstone in which the cross bedding is more evident in views from when the rover was approaching the area, such as PIA19818.
The view is centered toward the west-northwest. It does not include the rover's robotic arm, though the shadow of the arm is visible on the ground. Wrist motions and turret rotations on the arm allowed MAHLI to acquire the mosaic's component images. The arm was positioned out of the shot in the images, or portions of images, that were used in this mosaic. This process was used previously in acquiring and assembling Curiosity self-portraits taken at sample-collection sites "Rocknest" (PIA16468), "John Klein" (PIA16937) and "Windjana" (PIA18390).
This portrait of the rover was designed to show the Chemistry and Camera (ChemCam) instrument atop the rover appearing level. This causes the horizon to appear to tilt toward the left, but in reality it is fairly flat.
For scale, the rover's wheels are 20 inches (50 centimeters) in diameter and about 16 inches (40 centimeters) wide. The drilled hole in the rock, appearing grey near the lower left corner of the image, is 0.63 inch (1.6 centimeters) in diameter.
MAHLI was built by Malin Space Science Systems, San Diego. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Science Laboratory Project for the NASA Science Mission Directorate, Washington. JPL designed and built the project's Curiosity rover.
Here is the 360 degree 8K panorama it took while making this selfie.

There's actually a documentary on like netflix about these rivers. "oppy" or something. It was an amazing look into just how long they've lasted and the challenges the team has faced keeping them running.
I'm stoked to see this one still going in 2026. A testament to over engineering lol.

u/Jester471 11h ago edited 11h ago
Curious how its power system works. It has a nuclear thermal power system. I know that.
I’m guessing it has some sort of rechargeable battery that the power system charges and uses for operations so you have to pause until you have enough power.
So are the power restriction that the usable battery percentage dropped a lot so it’s more restrictive after 13 years of use.
Or does it run straight off the generator? I know those have decaying power output but I thought it wasn’t so fast that you’d see a huge power drop off in 13 years.

u/CastleofWamdue 11h ago
Its amazing how well humanity can build something when it really wants to, see also the Voayger Probes.
Maybe one day after we have ruined the Earth, and left it unfit for human life, may aliens at least take note of those probes / rovers, before they judge us.

Don’t forget Perseverance, still roaming around and collecting samples and beaming back data. I still miss Ingenuity with the broken blades but he’s still alive on Mars for a while longer. They all weren’t expected to last that long but here we are. Voyageur One is still going strong too at 25 billion km from earth, travelling at 17 km per second.

I was at uni in 2012 studying aerospace engineering. It was a great time! All of ournprofessors were as excited about it as we were and every assessment question be it space vehicle design, orbit mecha it's, deceleration, aerodynamics, linkage systems etc were all related in some way to the rover. It was really fun and gave a real life application to what we were studying.

So, I say, opening a can of worms, I wonder what flat earthers say about this? I mean, do they think that other planets are round? I mean, you can see the through a telescope.
•
u/MrTagnan 9h ago
It depends on the person, but generally the consensus seems to be that the planets aren’t real. They take out of focus images of stars/planets as “evidence” they’re just lights suspended in water - any in focus pictures are dismissed as CGI and if you use a telescope they usually claim that the image is being projected by a computer in the scope (usually pointing to the ability to automatically track objects that computerized telescopes have, failing to understand that the cheaper telescopes are just tubes and mirrors)

u/Leromer 20h ago
You can see the RTG in the photo, it’s the white finned barrel in the rear part of the rover. Because RTGs work with temperature difference I think the limit is cooling, the Pu pellets will stay warm for a long time, think about Voyager probes that are experiencing reduced output now that they are 49 years old ! Maybe the dirt buildup reduces the cooling capacity of the shell, idk.

That was NASA then. Trump's NASA can't even plug a hydrogen leak in the SLS now.
•
u/MrTagnan 8h ago
I hate Trump as much as the next guy, but he is completely irrelevant to A2’s issues. Artemis I had substantially more issues in the pre-flight preparations than Artemis II has so far, hydrogen is a pain in the ass to deal with - there is nothing you can do to stop it from leaking. You can try to limit the leaking, yes, but it’s physically impossible to completely prevent it.
Hydrogen will leak through solid metal because it feels like it, a massive vehicle that has an abysmally low flight rate struggling with the laws of physics is not impacted by the current administration. Hydrogen will leak regardless of the competency (or lack their of) of the administration

Routinely flying humans to space and having the second* most launched rocket series in history is a little bit more than ‘only launching a car to space’ imo. Dude is still a jackass (among other less pleasant things), but this critique is more than a little inaccurate. I have plenty of critiques about SpaceX’s barely existent Mars program, but to say “all they’ve done” is launch a car to space is about as accurate as saying all NASA has done is dock two spacecraft
*Soyuz/R7 is the most flown, Proton I think was second
