Scientists and engineers must overcome a great many difficulties to send a manned mission to Mars, Pang Zhihao, a space technology researcher in Beijing said. "First of all, Mars is very far from Earth - the closest distance is 55 million kilometers, which means a round trip will take more than 500 days. Second, putting a manned rocket into the Earth-Mars transfer trajectory will require it to be able to fly at the escape velocity, or 11.2 km per second." Other factors that should be taken into consideration include disturbances in communication between a Mars-bound spacecraft and Earth, sources of energy to sustain operations on Mars and astronauts' health risks caused by a lengthy stay on Mars.

In the fourth week of October the team of the second Qinghai-Tibetan Plateau scientific expedition launched sounding balloons and drones for the integrated observation experiment of the Southeast Tibet alpine environment. The researchers acquired data lon the temperature profile, relative humidity distribution, air pressure, wind direction and wind speed as measured from the surface to 30 kilometers height in the atmosphere. The newly collected data will then be combined with Fengyun satellite data, numerical weather models, statistical analysis, and diagnosis analysis to obtains high temporal and high-resolution models and 3-dimensional profiles of the layers in the Earth's atmosphere.
