This animated gif is comprised of images that were acquired by the Navigation Camera (Navcam) located on the rover mast, part of the Mastcam-Z instrument. Mastcam-Z is capable of acquiring videos (generally at about 4 frames per second), but sending this data back to Earth could take a long time. To send data to Earth, the rover transmits a signal to a ...

As of today, the debris shield has been dropped. The "tests" discussed in the article are electrical, computer, and sensor tests. Nothing mechanical (other than dropping the shield) has been done yet; the helicopter is still attached to the bottom of the rover. The official NASA article dated today explains that the rover is now on its way to a ...

Why didn't Ingenuity (helicopter) deploy immediately right after rover landing? For many reasons. Number one is that helicopter is an experimental (i.e., not mission-critical) item. Mission-critical aspects took a much higher priority. Another reason is that Ingenuity deployment requires the Perseverance to move to a flat spot, drop the helicopter from its ...

Yes and no. The no part first: Mars 2020 had sensors and effectors attached to the non-important parts of your diagram, many of which had various degrees of smarts. Star trackers are very sophisticated cameras. The have their own computers that control mode (e.g., lost in space versus locked) and that perform pattern matching on an self-contained star map. ...

So How did ingenuity helicopter clear tests even without being deployed on Mars? The linked article claims that Ingenuity has "cleared multiple system checks". By way of analogy, human pilots of aircraft on Earth perform or monitor all kinds of systems checks on the planes before the pilots even think of starting an aircraft's engines. Then they ...

The answer is up to around 10g/hour. The experiment will be run multiple times throughout the lifetime of the rover and each run will be for about an hour. A full scale version for use on a human mission would need to be many times larger. NASA suggests two orders of magnitude larger, but if Starship is used probably three orders of magnitude bigger. ...

Short answer: yes. Long answer is here (Thermal Response of the Mars Science Laboratory Spacecraft during Entry, Descent and Landing - Keith S. Novak): Flyaway Segment: at E+431 sec (see Figure 6) After the Bridle was cut, control of the DS was transferred to the DMCA. The DS traveled straight up above the Rover, before turning 45 degrees and thrusting away ...

since the question was answered properly, I wanted to add a tidbit I learned at a JPL event. MOXIE produces enough oxygen to keep a small dog alive.

The question now asks how Ingenuity was able to "clear tests" before being deployed to Mars. Both previous answers have discussed some of the testing regimes, but neither addressed actual flight tests...which was actually the OP's original wording. The Wikipedia article on Ingenuity says Ingenuity made test flights in a simulated Martian ...

From the DESCANSO MSL Article, cruise communications were done with a medium-gain antenna (MGA) and a low-gain antenna (PLGA). The spacecraft was spin stabilized: the interplanetary trajectory attitude control plan for MSL has the cruise stage spinning at 2 revolutions per minute (rpm) until shortly before entry into the Martian atmosphere. The cruise ...

This perhaps isn't the most useful answer, but from what research I've been able to do it seems that nobody cares. This seems weird, given the risk to the parachute, if nothing else. I can only imagine that the cover's very light weight and high drag ensure that it doesn't come anywhere near the rest of the lander or the parachute, and this is presumably so ...
