Mars 2020 's rover is as heavy as a small car, maybe it'll be escorted
by a small exploration helicopter


No oxygen in the atmosphere to help it burn fuel. I think a balloon would have been much more efficient.

I think the choice of helicopter was made because the helicopter's moves
are controllabler and quicker

Accept a ballon: to move it as you want, it would take a rover with a
string which holds the balloon, but the rover is very slow, and the
string's mass limits the height

Mars 2020's helicopter can fly three minuts and to charge itself by a
solar panel. It can go up to 400 meters hight

helicopter use will for locating rover's way and find interesting places

A balloon is a lot cheaper.I would go with 6 balloons all different sizes.Mars has little air pressure(1% of Earth's)I like water balloons too.(ice balls) Time to probe down as far as we can,or use explosives.Make a deep hole in the deepest crater.Hope to find Mars mud.Bert


Of course NASA will use the most expensive way to do things. After all, the taxpayer's paying for it!

The more NASA spends the more GOPer Mafia can steal.Nixon,Annenberg.Kissenger stole 2 billion for 43 years of shuTTLES.Bush made them look like pikers..Bert
