Assuming they're telling us everything that's happening on Mars, that is.
Where's the kaboom?
Yeah, let’s see how well that ping works when they find a deathclaw in one of those trips.
YOU DIED (several minutes ago)
Even worse...
Hey is that... man that's a weird looking boatfly...
Wait.
OHGODOHGODOHGOD

...the Voyager 1 team would like a word.
The programming described in the article is spectacular too. Imagine working with 68 KB of space. I got to talk to someone who worked on the team once, which was probably the culmination of my life.
I started programming as a kid way back in the ZX Spectrum days, and that one had even less memory than that.
You can do a surprising large amount of functionality if you're hand-coding assembly (I actually made a mine-sweeper clone for the Spectrum like that).
Even nowadays, there is the whole domain of microcontrollers, some of which are insanelly tiny (for example, the ATTiny202 which has 2KB flash and 128 Bytes of RAM) and you can do a surprising amount of functionality even in C since modern C compilers are extremelly efficient.
(That said, that 202 is the extreme low end and barelly useful, but I do have an automated plant watering system I designed - complete with low battery detection and signalling - running on an ATTiny45, an older chip with twice as much flash and RAM).
In my experience, if there is no UI on a screen (graphical elements tend to use quite a bit of memory plus if you're doing animation you need an in-memory buffer the size of the video memory to get double-buffering for smoothness and just that buffer can add up a lot of memory depending on resolution and bytes per pixel), using a compiled language which can optimize for size (like C) and not dragging in a ton of oversized libraries as dependencies, you can do a ton of functionality in very little memory - there are quite complex functional elements out there (like full TCP/IP stacks) that fit in a few KB of memory.
I saw an interesting video about the first drone that flew on Mars. They programmed the flights in advance and it then executed them autonomously. I think that is even more impressive, since it would not have been possible to intervene if something went wrong. At the time the data was received, the drone already landed
It's pretty amazing our first try at a fully autonomous helicopter on another planet flew and landed successfully 71 times. Rest in peace, Ingenuity.
Built with such a tiny budget that they used cell phone parts
IIRC that was part of the mission? They wanted to push themselves to see what could and could not be done with a very strict budget and cheap commonly available parts and tools.
It worked surprisingly well
They blasted a bunch of phone hardware with radiation and picked the ones that held up
They then build a custom Linux system and called it a day
That’s basically what spin launch did. They went and bought just consumer parts (not even the ones NASA could get/build) and put them into their centrifuge.
What's the word with spinlaunch these days? I feel like I've been seeing hype videos for like a decade and not a single article about progress/achievement/contracts.
Just this month they broke a 2 year silence.
That's actually super exciting! I'd be glad to see a player other than SpaceX make headway in the industry. Thanks for the reply!
It’s interesting and I love seeing the “payload yeeter” start to actually get traction, but iirc there is downsides. It’s not like you can just launch any old thing, the payload needs to survive more Gs and it only replaces the first stage. So still need fuel and propulsion.
So many interesting “hype” things either get lost due to development, or not panning out. So it’s always great to see when they “succeed”.
And that's using the same hardware as you have in your phone. Not similar, the same.A snapdragon 801. Such as used in Galaxy S5, from 2014.
https://en.m.wikipedia.org/wiki/List_of_devices_using_Qualcomm_Snapdragon_systems_on_chips
Snapdragon took care of image processing, guidance processing, and storing flight data—with readings 500 times a second—while the microcontroller was in charge of navigation and running the helicopter’s motors.
It's kinda mind-blowing that the same hardware from my trusty s5 (that is currently gathering dust in a drawer somewhere, rip) powered flight of a drone on Mars.
All of that with no GPS to get the location of the drone. They relied on a camera under the drone to basically act like an optical mouse sensor to follow the location of the drone.
I am not downplaying the supreme engineering of the mars rover team, especially because there is no GPS on mars, but DJI has pre-programmed drone flights that work with their consumer drones, called missions.

I've been thinking about setting up a mission for my drone to fly every week to gather data about what my neighborhood is like throughout the year.

I lived in Western Australia when I played WoW - 400ms was a good day.
Love of the game right there lol I'd have gave up
It's like playing Age of Empires over dialup. One minute you're happily building a little army and keeping your farms going. Then some asshole with cable internet comes along and faster than you can blink, your army is destroyed, villagers murdered, and your city burned to the ground.
I never figured out how, but it tended to feel impossibly early in the game too, as if the opponent had already been developing their economy for at least as long as I had before the game had even started.
It's been a few years since I've played online multiplayer, but isn't 100ms quite good?
1-40ms - good
40-70 - less good but playable
70-100 - can have affects depending on the game
100-150 - not great
150+ - unplayable
It depends on what type of game you are playing, and how good the game's lag compensation is. I've played games just fine with a ping as high as 200ms.
I used to play Quake with around 300. I would have loved 100.
good luck railgunning someone who's rocket jumping with 300 ping

Depends on the game. In fast paced games 100ms ping may negatively affect the gameplay (though normally the game is still playable), but in slower paced games it normally doesn't matter that much yet.
I gave up sim racing online after a crash and seeing the other players replay of the crash. I didn't think I was at fault but because of the lag, I totally was.
My ping from Australia to Europe was just too much in order to ensure others could have a safe race. When everyone else has 20-40 ping and I'm racing with 150+ it's just too much lag to be safe on the track
Somebody I know that does sim racing on a team has a dedicated internet connection just for racing. A few too many times of somebody starting up something like a Netflix stream in the house and it would spike his ping enough that it had dire consequences to his rating. That just seems crazy to me. He justifies it by it costing him like 3-5 races to play catch up after an incident. Doesn’t really help in your case as your ping was consistently poor though.
Running like the good old days though when modern cell phones didn’t exist and the house only had one computer…you just plug the modem directly into the computer. No router/wifi.

Forget NASA, 100 ping is pretty good for internet gaming...in the dsl days. Sure your warthog or ghost might occasionally plow into the wall of a canyon but the brain adapts.
EA: hold my beer
For example: in FC25 you can have 14 ms ping to the server, but still have a laggy experience as if you are playing with 1,400,000 ping.

Honestly, it depends on the netcode implementation.
TF2 hitscan and projectiles work remarkably well even at 100+ ping.
TF2 melee hit detection functions like a dice roll above 40 lol.
It would be comparable if NASA scientists were racing against someone else controlling another vehicle over there with less ping.
P.S. I'm not saying it isn't challenging - it surely is, but it's like connecting to your home computer over a shitty connection to play a single player game.
I regularly played with ping 100-150 and still managed to make it to the top 32 players
