Will InSight be able to pick up vibrations from the landing of Perseverance or Tianwen?

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. ...

Does Tianwen-1 mission have a skycrane camera and parachute camera like Mars 2020?

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 ...

Does Tianwen-1 mission have a skycrane camera and parachute camera like Mars 2020?

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 ...

Why do the Mars pictures sent by Viking 2 and the Chinese Lander show quite different landscapes of the same Utopia Planitia?

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 ...

Was Tianwen-1 the first "triple-depl"? (orbiter-deploys-lander-deploys-rover-deploys-selfie cam) What are the highly hierarchical deep space missions?

I believe that NASA's Mars 2020 mission beats both: Cruise Stage deploys (aerodynamic) Descent Vehicle ("Aeroshell") deploys (rocket-powered) Descent Stage ("Skycrane") deploys ...

Why do the Mars pictures sent by Viking 2 and the Chinese Lander show quite different landscapes of the same Utopia Planitia?

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 ...

Will the Emirate Mars Mission, Tianwen-1 and Mars 2020 Mission get closer to each other or spread out on their way to Mars?

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 ...

Does Tianwen-1 have a near-repeat ground track orbit in order to scan the same general area on each of its low altitude passes?

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 ...

For the three spacecraft now on their way to Mars plus ExoMars, how many have any solar power capability during transit?

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) ...

Could Tianwen-1, Hope, or Mars 2020 image one another en route to Mars?

(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 ...

Why is it so cold in the nighttime (-130 C at 25.1 degree North) at the location where the Chinese rover landed on Mars?

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 ...

Why (the heck) did Tianwan-1 insert into a low inclination orbit then execute a plane change from 11.8 to 86.9 degrees?

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 ...

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 ...
