Salon has an article on Ingenuity.

In 1903, Orville and Wilbur Wright flew a plane for 12 seconds, 120 feet in the air, on what is now known as the first powered-controlled flight on Earth. Now, 118 years later, the first powered-controlled attempt at a flight on another planet is about to take place.

According to NASA, Ingenuity — the four-pound rotorcraft attached to Perseverance — is on its way to its "airfield" on Mars.

The space agency announced that its target for its first takeoff attempt will happen no earlier than April 8, 2021.

Ingenuity was designed as an experiment to see if it is possible to fly on Mars as we do here on Earth. And the process leading up to the takeoff is a very meticulous one. Consider how long it took humans to stick a powered-controlled flight on Earth; given Mars' thin atmosphere and a twenty-minute delay in communication, it is arguably more challenging on Mars.

"As with everything with the helicopter, this type of deployment has never been done before," Farah Alibay, Mars helicopter integration lead for the Perseverance rover, said in a press statement. "Once we start the deployment there is no turning back."

Every move for the next couple of weeks could make or break Ingenuity's success — starting with precisely positioning the rotorcraft in the middle of its 33-by-33-foot square airfield, which is actually a flat field on the Martian surface with no obstructions. From there, the entire deployment process from Perseverance will take about six Martian days, which are called sols. (The Martian sol is thirty-nine minutes longer than an Earth day.)

Good luck, little chopper!

    If they're using Falcon 9s, they probably could get a ratio of 20 tons of cargo and 40 tons of propellant/booster (I'm going with chemical propulsion on a Falcon 9 upper stage). So 60 Falcon 9 launches would handle putting that stuff in Mars orbit. It still needs to get to the ground near the desired landing point on Mars and some payloads would be lost. My take though is that you probably can get it done in 100 launches from Earth. using present day launch technology. At $80 mil per, that's $8 billion in launch costs (ignoring significant economies of scale).

    Batteries (yet to be invented - few chemistries -100C over the Martian night, cabling, equipment for transporting them in place (I doubt that the precision of Mars drops would be less than 10km radius) and assembly. And that's just the power.

    Air, water, short term shelter, food, recycling facilities. Protective equipment - you ain't gonna be able to repair the spacelike suits soon. Local comms, transponders, satellite dish for orbit.
    Binders to make bricks/beams/etc from Mars soil. Mini-earth moving equipment for building permanent shelters.
    Medicine/bandages, surgical equip, sterilizers, etc. - get to the closest hospital in about a year travel time.
    Entertainment - they'll be isolated.

    Mate, we aren't going to see them in our life time. The programme is gonna take longer than two election cycles and the govts will interfere.

      So you're telling me that the problem is hard, it might require a lot of mass from Earth, and someone will probably need to work to get that stuff to work? Who knew?

      I'll just note that there are people who deal with hard space problems now, we have launch vehicles capable of putting the necessary mass into space now, and it's going to be a 25 person settlement, which means we would have some man-power out there with which to put stuff together when we'll need it put together.

        I'm telling you that is going to be a "super slow exploration".

          "Super slow" compared to a few token unmanned missions a decade? No way.
