> On the second day of the mission, Wang floated over to his experiment and sought to activate the Drop Dynamics Module. But it didn't work. He asked the NASA flight controllers on the ground if he could take some time to try to troubleshoot the problem and maybe fix the experiment. But on any Shuttle mission, time is precious. Every crew member has a detailed timeline, with a long list of tasks during waking hours. The flight controllers were reluctant.
The only justification for human spaceflight at all is that humans can fix things that a robot can't yet. Sounds like the whole approach to the misison profile was flawed, especially as he ultimately got it working.
Meanwhile the robots just quietly go about their work collecting almost all the data we have from space and celestial bodies.
