The cartoon characters are the mascots for the 2022 Winter Olympic games & the Winter Para Olympic games. The panda figure on the left is for the Olympic Games and the red figure of the right is for the Para Olympic Games.

I really hope it won't be able to detect Hope, that's orbiting Mars, not landing on it. InSight was actually made to detect these impacts, as it can help one to understand more about Mars. Fundamentally a heat shield impacting is just a particularly dense meteor. I think it is likely it will detect Perseverance. The two are fairly close. Specifically it ...

The Wikipedia article on the Tianwen-1 mission describes the landing sequence quite well: It is projected to make an atmospheric entry followed by a descent phase under parachute, after which the lander will use its propulsion to land smoothly on Mars. If all goes according to plan, the lander will then deploy the rover designed to explore the surface for ...

Does Tianwen-1 mission have a skycrane and parachute camera like Mars 2020? No. My reference is this video: 3D animation: how will Tianwen-1 carry out China's first Mars exploration mission? from a Chinese news outlet. To me, it looks like it will use a similar approach compared to InSight/Phoenix/Viking with the rover mounted on the top. It will then ...

Pick any area or larger crater on Mars (Hellas, Isidis, Elysium, Argyre...) and go to inspect them under high res visible imaging on Google Maps Mars, or better on the 3-D version of that, Google Earth and then Mars. You will find that any of those regions contains a large variety of terrains on the scales of tens to 100s kms, smooth ones, chaos terrains, ...

I believe that NASA's Mars 2020 mission beats both: Cruise Stage deploys (aerodynamic) Descent Vehicle ("Aeroshell") deploys (rocket-powered) Descent Stage ("Skycrane") deploys Perseverance deploys Ingenuity That is four deploys compared to the three you listed, and happened about a month earlier.

Utopia Planitia is a large plain, some 3560km in diameter. That's only a little less than the distance from New York to Seattle, so a variety of terrains within it shouldn't be surprising. I didn't find coordinates for the actual landing site of the Zhurong rover, however the target site was reported earlier, which is 1758km from the Viking 2 location. So ...

Only the mission operations team for each mission can answer that question. During an interplanetary mission, spacecraft perform Trajectory Correction Maneuvers (TCMs). These are used to better target the B-Plane target (as explained in the documentation for FreeFlyer). The selection of the B-Plane depends on many factors, such as the thrust capability of ...

Plugging in a periapsis altitude of of 265km, apoapsis of 12,000km, inclination of 86.9 degrees, and right ascension of -10 degrees (so the groundtracks would pass over Utopia Planitia) yields these groundtracks for the satellite with respect to the IAU_MARS body fixed reference frame: The parts of the groundtrack where the dots are more spread out signify ...

I would guess all four spacecrafts use solar power during transit. Tianwen-1 seems to have solar power during cruise: Power: Solar cells, batteries (cruise stage) Solar cells, batteries (rover) Source: https://space.skyrocket.de/doc_sdat/tianwen-1.htm Hope spacecraft also has solar power (but here it says they will deployed "once in orbit"): ...

(If one of the commenters posts this as an answer, I'll delete my answer and accept theirs. They did the hard work.) No, none of these spacecraft could image one of the others, for two reasons. This answer based on trajectories in Horizons shows that the closest approach of any pair is (was) about 1 million km between Tianwen-1 and Hope, circa 2020 July 20....

Breaking News! (01:24 UTC June 8, 2021) China releases new Mars image taken by Tianwen-1 probe, CCTV (English) Article shows before and after picture of the landing and associated debris: ...taken by a high-resolution camera installed on the orbiter of Tianwen-1 at 6 p.m. on June 2 (Beijing Time) Now to feature map this with HiRISE data for some more ...

Unfortunately Insight's subsurface thermal probe is not in place so we don't have data from Mars, but what it would look like is at say 50 or 100 cm below the surface the temperature was constant, but closer, within say a few centimeters of the top, the surface temperature would drop every night and rise every day. Rock and especially loose soil is a lousy ...

A direct insertion into a polar orbit gives you only one option for an orbital plane: one that's initially pointed straight at the Sun. This is sub-optimal for an observation mission, since you're more or less directly over the sunrise/sunset line, and can only see deeply shadowed ground. It will be several months before the planet moves far enough in its ...

The hopelessness of my question expressed in this answer now seems "greatly exaggerated". Only the mission operations team for each mission can answer that question. Of course for detailed and reliable trajectories one will need TCM data, but to answer this question, I think we have enough now. Will the Emirate Mars Mission, Tianwen-1 and Mars ...
