Hi @nexsi. First of all, why a helicopter? What advantage can we get if NASA spent a significant sum of money to build a helicopter which can transport humans to Mars?

I have a few suggestions to add for your article:

• You need to cite your images' references. The first image, is it yours? Because it was watermarked with @destasteem so I'm kinda unsure whether you are the one who edited that or @destasteem. If the latter, you need to ask for their permission and attribute it to @destasteem.
• You need to cite your article reference.
• In my opinion, you need to write some more. Make it at least more than 300 words.
