正解

Creating materials that can survive extreme heat and intense radiation.

How could a fusion engine impact the duration of a trip to Mars?

It could cut the travel time from 7-10 months down to 3-6 months.

It would keep the trip duration the same but improve the comfort of the crew.

It would make the trip significantly longer due to the weight of the reactor.
