Nope.  They're clearly IFO's.
Gyro:
It's now hovered at 5m high and moved 2m laterally! Any guesses on the next daredevil flight manoeuvrer?  ;D

In other news (later in the same article), we have commenced the mission to pollute the Martian atmosphere with Carbon Monoxide, that didn't take long!


--- Quote ---Also running further tests will be the team behind Moxie - the Mars Oxygen In-Situ Resource Utilization Experiment.

This toaster-sized device, which lives in the belly of the Perseverance rover, also posted an exploration first by drawing O₂ out of Mars' air.

The planet's atmosphere is dominated by carbon dioxide at a concentration of 96%. Oxygen is only 0.13%, compared with 21% in Earth's atmosphere.

Moxie is able to strip oxygen atoms from CO₂ molecules, which are made up of one carbon atom and two oxygen atoms. The waste product is carbon monoxide, which is vented to the Martian atmosphere.

The Moxie team is running the unit in different modes to discover how well it works.

The expectation is that it can produce up to 10 grams of O₂ per hour.

Actually, I'm not sure I follow chemistry of that one though...  CO2 -> O2 + CO ?   :-\

An impressive Oxygen production rate though. I suppose if it wasn't producing a gaseous waste product, it would end up with a big pile of carbon!

Probably this:

"CO2 splitting, CO2 → CO + 1/2 O2"
Gyro:
Ah yes, that makes sense. I was thinking in terms of 'you can't have O' rather than '1/2 O2'.

ARRGGHH!!!  . . .
Oxygen exists in a Diatomic state/molecule.
2 x CO2  -->  2 x CO  +  O2    :box:
