Why isn't NASA having a ground-based solar panel to charge the Li-ion batteries on board the JPL Mars Helicopter?
They say that it is going to take a day for the current on-board Solar Panels to charge the batteries. So why not have larger ones on the ground, which could charge it faster?
Is it because it isn't needed for this project since it's just a technology demonstrator and not specifically for science missions. So they don't want to add more payload because it will increase complexity in deployment etc. And that they might have it for future missions which will be specifically for collecting scientific data? Or is it something else?
