Rover Definition and 27 Threads

NASA people are excited about a new (old actually) rock that their rover Perseverance found a few days ago. Space.com article here. Short NASA video:

Found this interesting feature when panning through the Perseverance 360.

1. ρmars atmosphere = 0.02 kgm^-3 volume of a sphere = 4 / 3 𝜋 𝑟^3 gmars = 3.8 ms^-2 So: Volume of a hemisphere=2/3 𝜋 𝑟^3 r=7.75 m Archimedes' principle states that the upthrust on an object is equal to the weight of fluid that the body displaces To find the upthrust produced...

NASA'a rover prototype floats up to the bottom of the surface ice and rolls around looking at things. It has been tested in Alaska and the Antarctic. This NY Times article has videos of it moving around and of what it sees under the Antarctica ice.

I’m wondering if a lander/rover landed on an asteroid with a very low gravity, and we wanted to make said rover move around the asteroid, would it “float” away because of the low gravity? Wouldn’t the normal force and the gravitational force equal 0? If we added a propulsion system, how would we...

Hello all: I was seeing all the news about rover mission , but catch my eyes that rover was stopped due to a dust storm , maybe it's solar panels is covered with dust and the batteries charging in its minimum for that reason . is that possible best H

i'v googled the subject and it seems like a serious problem, e.g. the dust accumulating on the solar panels, there has even been a term coined 'cleaning event' for Mars winds, as if this is a matter of luck to get the solar panels cleaned. A small carbon-dioxide vent on the tip of the rover...

Hello everyone! This is my first post here so please excuse me if I don't have the format right yet. Background: I'm a Mechanical Engineering student working on a robotics team and I'm tasked with designing the wheels. The robot is currently using 5 in radius wheels with old motors. The...

What's the scale on Mars rover Opportunity's "Microscopic Imager" images ? I'm trying to work out if the Martian "fossil" shown could be the impression of a cross-head-screw ... http://mars.jpl.nasa.gov/mer/gallery/all/1/m/3720/1M458433044EFFCEQKP2955M2M1.HTML

I have to design a space rover for Mars that has to have quite a few operating gadgets on it. Without giving a lot of details I am using sketch up and needless to say it sucks. I can't even figure out how to make a wheel. and I can't make objects at angles, like shafts or motors or anything...

Curiosity Rover makes "Earth shattering discovery"! Universetoday.com Hope it doesn't end like the Clinton fiasco.

I am studying about various payloads that can be used on a planetary rover; I want to know their size , weight , what does it do ; and what is the science that it uses ; Where will I get this info... ?

Can someone please point me to a deceleration graph over the 7 minutes of terror from the 13,000 mph re-entry speed through to the parachute release and landing of the Curiosity Rover on Mars? Thanks very much. :smile: PS: Mods please feel free to move this topic to the appropriate forum...

Beautiful animation. Landing system is novel and elegant. Hovering rocket platform lowers the vehicle on a cable to the the ground and then goes away. A lot of the deceleration work at Mars is done by the planet's atmosphere, saving fuel weight. Great stuff. Launch of "Curiosity" is...

I want to know why someone hasn't built a 'rover' of some sort that could easily navigate the lunar surface while recording HD video. I don't think funding would be an issue since you could easily strike a deal with a large company pertaining to product placement i.e. a coca-cola bottle in the...

Is a very low powered fission reactor (~25kWe) feasible for powering a large (car sized) Lunar or Martian rover? Or is it impractical (today) due to weight, size, radiation, or another technical reason? I understand that radioisotope thermoelectric generators are planned for future Mars...

Is there actualy any hi-res footage made with MARS rover?? All I see are computer animations, photos and low-res low-fps black&white clips. Can anyone point to some link where any Mars rover recorded a hi-res video?

http://www.spaceflightnow.com/news/n0509/01marsrovers/ Astounding to think the rovers only had a such a limited life span expectation to begin with, yet they are still going so strong nearly two years on. I wonder if they could carry on for a few more years yet?! After all the Martian...

On sol 61 of it's mission the Opportunity rover sent back some photos of an unusual object, have a look at the images on the NASA site http://marsrovers.jpl.nasa.gov/gallery/all/opportunity_m061.html

Another “MAJOR” finding by Mars rover to be announced Tuesday. On Tuesday, March 23 at 2pm, NASA and the Mars rover team are going to make another announcement about a major scientific finding by the rover Opportunity. No word yet on what the discovery is, but it should be big since they’re not...

I'm doing a research paper <again> and I need information on the Mars Rovers (Opportuniy or Spirit or both) and what materials make up those rovers and how physics is applied there etc...im really just starting to learn physics so i don't know much

Last night I was looking over some of the raw images taken by the Spirit rover on the JPL website. Particularly here: http://origin.mars5.jpl.nasa.gov/gallery/all/spirit_p067.html Sol 67 (March 11) Spirit Pancam images. According to an official press release the rover woke up at about 2:00...

First view of the Earth from the Martian surface...Orion constellation...partial solar eclipses. Fun stuff. http://www.cnn.com/2004/TECH/space/03/12/mars.earth/index.html
