Could Ingenuity survive if Perseverance failed?

No. Perseverance is the communications relay for Ingenuity. Ingenuity uses essentially ZigBee to communicate, the same protocol that possibly your smart bulbs use. ZigBee has a range of about 300m ...

Has a mockup/analysis of the Ingenuity 'bad landing' been created/posted?

NSF/Intrepid Museum's interview with Travis Brown, PhD, Ingenuity's Chief Engineer contains some discussion on post-crash conclusions. I don't know if that actually falls under the umbrella of what ...

Why didn't Ingenuity (helicopter) deploy immediately right after rover landing?

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 ...

How did the Ingenuity helicopter clear tests even without being deployed on Mars?

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 ...

Mars helicopter ingenuity stress testing at end of mission?

In some sense, it already is. Ingenuity was designed for 5 short test hops during the first 30 days. Pretty much every flight since then was higher, farther, and longer than originally designed and ...

Why wasn't the high-speed rotation regime for Ingenuity tested on Earth?

Ingenuity is a low cost technology demonstrator. As a technology demonstrator, NASA and JPL cut lots of corners to keep the cost low (low by NASA standards, only \$80 million US compared to the \$2.2 ...

Could a helicopter escape Titan?

Good luck getting a helicopter hypersonic. You need more than 2,600 m/s to escape Titan. The speed of sound on Titan is 194 m/s.

For how long could the Mars helicopter Ingenuity keep up with the Perseverance rover if it wanted to?

There are two parts to this question. The first is, can it physically keep up? As you mentioned, the range of 300 m per flight is specifically stated. From this page, we can deduce that one 90 second ...
