I witnessed this incredible launch by the Chinese entrepreneurial launch company @Linkspace_China. The wind was blowing 20 knots, yet they launched, hovered for 30 s at 100 ft, and then landed 20 inches(!) from the center of the same pad they took off from. #Space #Science #Mars https://t.co/o3CY8p9HUo
