The environment of the world Shina and her team was about to enter was extremely harsh, with different air composition, weather conditions, and lethal temperatures.
To counter these environmental conditions, Shina's team had two options.
The first was to don their scaffanders, which were engineered to provide a safe, breathable atmosphere and temperature regulation. However, they drew too much attention, and could limit mobility.
The second option was to use advanced technology that would allow them to take control of a native's body. This technology was commonly used in many interstellar operations.
Bing Shi found a few pods that looked like this technology inside the old ship. She wasn't confident enough to use it on another species. This technology was too complex and required a team of experts to operate, which she didn't have.
