The rover that is still working is the Curiosity rover. The Opportunity rover went dark in the dust storm, and hasn’t been heard from since.

Was cool.
Very interesting topic.
good bump, first time seeing this thread
subbed
It is sol two-thousand-406, so a couple fun photos from the camera on the arm that came down from over the weekend.
Frame from another selfie:

Night time image of drill hole from ~75mm, light from LEDs on camera:

Wow! Great to see another update and I'm happy everything is still functioning fairly well.
And where have the last 6.5 years gone?
Look at that fucking hipster [emoji12]Quote:

It’s kinda amazing how much Mars looks like a western desert landscape, even down to the dirt.
Awesome
Took these last night and they arrived this morning, cool looking features and different looking rock than I recall seeing. Camera on the robotic arm and is 5cm standoff. Surface is dusty and in full shadow, so not the best photo...

Fascinating... looks kind of like corral. Is that from water or just wind blown erosion? Or both?
Neat!!!
Have you solved the biggest mystery about Mars?
Why is it so red? Iron oxide?
That is really fucking interesting. Definitely water. 50mm? That's really close for a fucking droid. Nice portrait. Holy shit, I'm still digesting this. Awesome. FKNA.
But with even more amazing rock formations thanks to the low gravity, e.g. the floating spoon:Quote:

I'm pretty sure we've know that since the Viking missions in the '70s, if not before.Quote:

Rover is a lot like MSL, better wheels, bigger arm, and has a different sample system. Also the helicopter experiment looks cool. Same Rube Goldberg EDL design.
Some changes in the science payload. Our company built more cameras than MSL, but we are operating fewer on the surface. 2 cameras on the mast (now with zoom), for ASU, joint surface operation with ASU and MSSS. Built 2 of the cameras on the arm for JPL, one we operate. I camera for EDL for JPL, JPL operates. I'm involved with the arm camera that is like the MSL MAHLI.
NASA info about launch and link to watch it live:

I found this video touching, I typically don't use the public outreach names for the rovers...but I agree they picked a good one for m20:

Fingers crossed for a successful launch!
helicopters on mars...heliskiing Olympus Mons coming soon (after the CO2 snowmaking system goes in)
Hoping for a successful launch!
So, Mars is basically Nevada?
I think I saw walter cooking in one of the scenes... so maybe west of Albuquerque.Quote:

Successful launch

and spacecraft in safemode right away (during first Earth shadow) :eyeroll: shouldn't be a big problem, but kind of classic 2020.
a pesar de parecer una simulacion el vídeo ese, me gusta
This image arrived over the weekend and at first glance I thought it was from Lake Powell. Dunes look like water.

Another great shot. Such an interesting landscape for being so barren.
Fantastic! Looking forward to what the next rover can do.
Question, 406: Do you use photogrammetry to combine the imagery? If so, for what use? VR, volume measurements, simulations? Curious...
People on the team do, but fanciest I get is red-blue stereo :-).
I think JPL put out some youtube(?) VR and there might be some public data available using the microsoft headset.
Hobbyist also do some of the coolest things with the images.
Thx, have to check out!Quote:

Not looking forward to being on Mars time again. Last time, was living in a rental apartment in Pasadena commuting to JPL and single. Married with 3 kids and working from home this time around. Should be interesting. On the plus side, just have the camera on the arm this time around...so hopefully less to worry about.
Please post updates and images as able. StokedQuote:

Havent had the time to check out properly the NASA site how things have been done (the website in the video), but looks really interesting.
Imagine that in VR?
I had to google it. Never occurred to me.

JPL has a nice EDL animation: https://www.youtube.com/watch?v=rzmd7RouGrM
What could possible go wrong? :-)
History has said these things always work out, so I’m not worried.
Real question though, and I know it’s not your area of expertise necessarily, but why are these landings always so complicated? I’m sure they’ve figured out that it’s safer this way, it to me, that many things having to happen perfectly or it fails seems like a recipe for disaster.
^^^I have a lot of thoughts on the topic, but probably shouldn't put them online. It is risky regardless. But I have never seen an explanation of why the sky crane is better than designing the powered descent stage so the rover sits on top or in and then drives off/out after landing.
Play some Kerbal Space Program. Seriously. Rocket science is really, really, really fucking hard. So many trade offs and it all boils down to deltaV.Quote:

Lots of physics benefits as long as the computers and sensors hold out.
This is so funny, on so many levels... :DQuote:

m20 landing in 18 hours! https://mars.nasa.gov/mars2020/
Oh no, I know exactly whom I was directing that to. That game gets a lot of the physics correct enough to illustrate the bigger points, and can be pretty unforgiving if you're not thoughtful about how you design your ship. It doesn't incorporate Murphy's laws when one of your thrusters fails on decent and throws you into a spin, so at least you have that going for you.Quote:

Many landed only to tip over after the thruster shut off because the ground wasn't level enough. Now think about landing a craft with a small car on top of it, on unlevel ground, without a pilot and NOT tipping it over.
Back on point - this is about roll stability in aircraft, but many of the points carry through to descenders. Self stabilizing craft to get the rover to the ground are desirable. The Sky Crane design with a dangling pendulum payload is more stable than many other designs as long as it remains within the flight envelope, which leads to the rover landing rubber side down.
