【题目】

After people have been used to their new work situation. But what if your job was to control a multi-billion-dollar space rover (探测车) located on a planet nearly 200 million km away from Earth?

A team of NASA scientists is doing just that. In order to follow social distancing rules, these scientists have had to work from home. But they’ve still found ways to work together and take care of the complex (复杂的) tasks that are needed to keep the Curiosity rover working on Mars.

Their work-from-home setups (装配) as seen in photos provided to CNBC and ScienceAlert, look much like home office setups. They use ordinary computers. But instead of working on spreadsheets (电子制表), these scientists are programming complex sequences (序列) of instructions that are then sent to the rover. These instructions allowed the rover to find a rock sample (样本) in a location on Mars called “Edinburgh”.

Usually, the team’s 20 scientists work together by communicating through apps or video meetings. One scientist might have to follow 15 message channels (通道) at once.

NASA gave the scientists headsets (耳机) monitors and other equipment to allow them to do their jobs from home. However, the goggles (眼镜) they usually use to analyze (分析) pictures from Mars could not be sent out. So they have to depend on red-and-blue glass lenses (镜片) instead.

But difficulties like these have not been a problem for the scientists. In fact, getting used to changing situations is “classic, textbook NASA,” according to the head of science operations Carrie Bridge. “We’re presented with a problem and we find out how to make things work. Mars isn’t standing still for us; we’re still exploring,” she said.
