First of all, Ingenuity has to survive the nights until it can be properly deployed on the surface, although it has power from Perseverance to do so. This probably isn't a significant issue, it has a protected case to allow it to survive EDL which will be ditched prior to deployment. It should be fine there for a while. Then it has to be deployed, and ...

From INGENUITY MARS HELICOPTER landing press kit: Mars has beyond bone-chilling temperatures, with nights as cold as minus 130 degrees Fahrenheit (minus 90 degrees Celsius) at Jezero crater. These temperatures will push the original design limits of the off-the-shelf parts used in Ingenuity. Tests on Earth at the predicted temperatures indicate they should ...

Mission design can be used for the trajectory designers, working iteratively with various other teams to come up with a feasible mission. Trajectory design and navigation can also be termed flight dynamics, and then mission design can include flight dynamics but also can be a systems role, helping interface between many teams to design a mission that meets ...

I think this term varies by organisation. In my expereience it is a multidisciplinary topic. Whilst a key part of mission analysis is how to get to and around the orbit, as large an effort has to be put into: what orbit is needed in the first place (is it even a satellite, how do different orbit options meet the payload requirements best) and which way does ...

For the shuttle program this work was called "flight design". Acronymology: DM - Organization code for Flight Design and Dynamics Division GPC - General Purpose Computer ISS - International Space Station LVLH - Local Vertical Local Horizontal OI - Operational Increment Rbar - Radius vector TORRA - Twice Orbital Rate Rbar Approach Vbar - Velocity ...

Yes, there are people whose sole job is "mission design." They design the trajectory that a spacecraft should follow to fulfill its mission and all of the maneuvers needed for that to happen. Some companies specialize in mission design consulting, like Space Exploration Engineering, Advanced Space LLC, or the X Team from JPL (although the latter ...

Credit: NASA/JPL/University of Arizona/USGS Click on the image, and then again for a closer view. The image above is a part from HiRISE,Digital Terrain Models and shows a colored elevation map of the eastern part of the delta deposit. (Purple is -2679 m, brown is -2388 m, so a full-scale elevation difference of about 300 m.) I would say the shaded, south ...

After carefully cross-referencing the landing ellipse picture with this topographic map provided by ESA, it looks like the cliffs in the center of the ellipse are about 50 meters tall, and no more than 100 meters.

Are launch windows to Mars avoided if they result in landings during dust storm season? No. It's pretty well known that the gusts of wind on Mars are relatively harmless to a person standing on Mars (one of the big things the movie The Martian got wrong). Even though winds on Mars could reach up to 130 km/h, the atmosphere is very thin and thus does not ...

A bare carbon fiber layup will degrade quickly, because the epoxy that holds the fibers together weakens with exposure to ultraviolet radiation, which is much greater outside the atmosphere than on Earth's surface. A good paint would help. Also, the epoxy also weakens (softens) with exposure to the kind of heat that sustained solar exposure would cause. ...
