So I decided to get a bit into Python in my holidays and made a script by myself! I posted it on GitHub, so feel free to use it if you want :) https://github.com/compidev/perseverance-raw-images-downloader

The following is sourced from Wikipedia's Kilopower:. An actual 1-10 kW, small, self-contained nuclear reactor, with built-in Stirling power converters to output electrical energy. They are very compact (even with allowance for the radiative cooling vanes, cheap, and reliable. OK, I am lying about that second attribute. As with anything nuclear, cheap does ...

A team of about 350 scientists and engineers are keeping "Mars time" right now ! From Business Insider's article "Now on 'Mars time,' NASA's Perseverance team shifts their work hours 40 minutes later every day" on Feb.20, 2021: At NASA, the team of scientists and engineers behind the Perseverance surface operations have to work around ...

It appears that they are doing so, but on Twitter and Facebook.

Really great answers as to the "how". The one thing that must come before any inserted gases is a magnetosphere. Otherwise most of the new gases will be carried along with solar wind. I know it sounds like 1950s sci-fi, but a viable low-tech solution would be domes and tunnels. Once humans have a solid footing on Mars I would expect the new ...

The system being used is Hololens, by MicroSoft. It was programmed by JPL's Ops Lab. They have a video of the project, though it seems more geared towards promoting it than documenting it, here. The current state of the tech is shown in this BBC video, while this one from a couple of years earlier shows the experience of viewing the Martian surface this way, ...

On what kind of martian soil or rock will the Perseverance rover drop its helicopter? A flat surface made from pebbly regolith and some small exposed flat rock, but with enough texture for the helicopter's navigation cameras. The first image shows a detailed image of the soil under the rover where the cover was dropped, the second shows the "runway&...

Computational Analysis of a Prototype Martian Rotorcraft Experiment, by folks from Pennsylvania State University and Ames Research Center. The linked version of the paper was published in 2002, but ResearchGate have a copy (that I haven't read) from late 2001. The prototype Mars rotor is currently being tested at NASA Ames Research Center and a ...

There's quite a few devices installed inside the chassis. Rover's own "essentials" necessary for the rover to operate - the computer, radio electronics, batteries for burst power usage, power supply units, inertial sensors etc. MOXIE - the 'oxygen maker', a test article, downscaled device that would supply Mars base with oxygen made from ...

Like a car body, the rover body is a strong, outer layer that protects the rover's computer and electronics (which are basically the equivalent of the rover's brains and heart). The rover body thus keeps the rover's vital organs protected and temperature-controlled. The warm electronics box is closed on the top by a piece called the Rover Equipment Deck. The ...

No. Ingenuity's purpose is just to demonstrate that we can fly on Mars, as has been stated many times throught NASA and ULA webcasts of the launch and landing. Perserverance is the only one that will be searching for life. It would make no sense for NASA to a camera that could search for microbial life when it would never use a camera on Ingenuity for that ...

For spacecraft/astrodynamics modeling, the acceleration due to the solar radiation pressure is specified in units of the solar flux: Watt per square meter as measured at 1 AU. As derived in the MathSpec of Nyx, to calculate the solar flux at any other point, simply divide the solar flux at 1 AU (which was about 1367 some years ago) by the norm squared of the ...

The original poster on reddit seems to have come to a conclusion to their question only a couple of days after posting it, and I've not found anything that seems to contradict their conclusions. Here's a better shot of one of the locations which had a photograph in the OP: These are the sample tubes being loaded into the rover. You can see the clear gas ...

What was going to on Mars was only the rover, all the remaining parts were "support garbage" to be disposed. Sycrane/descent stage does not even have a flight computer: it was driven by rover brain! After umbilical cut, a very simple logic onboard DS was activated: "fly up for some seconds, then turn." Engine is not even controlled, it ...

From this NASA press release, SuperCam got its first readings on March 9, two and a half weeks after its landing on the red planet.

Supplemental and possibly temporary answer. The orbits are quite different, some very eccentric with very close approach, some always close, some always far away, one is even going "backwards"! I'm not sure they all have helpful names, perhaps best to treat each one as unique? Spacecraft ecc inc semi peri apo ...

Many of the active artificial satellites currently orbiting Mars are in highly inclined orbits, as one would expect, since this increases the amount of the planet they can survey. 2001 Mars Odyssey: 93 degree inclination Mars Express: 86.3 degree inclination Mars Reconnaissance Orbiter: 93 degree inclination Mangalyaan: 150 degree inclination MAVEN: 75 ...

Spacecraft heading for Mars will launch away from Earth orbit on a transfer obit that is effectively an orbit around the Sun that intersects the orbit of Mars. On arrival at Mars the spacecraft will enter the upper reaches of the Martian atmosphere causing frictional breaking and will be slowed down into Martian orbit. The exact Marian orbit will depend upon ...

[Disclaimer: I have no source for this answer: it's too long for a comment though.] It's helpful to look at the overall image: these marks appear at the right of the image, at the bottom of a slope. There are also some interesting characteristics of the marks: as you say they're not completely continuous, but also they all have little black dots at the end ...
