Those who argue for the continuation of space exploration say that the benefits outweigh the great financial costs. One such argument is that many scientific advancements, such as the artificial heart, were partially a result of space exploration. Another benefit mentioned by those in favor is that the insulation used to keep homes warm is now more efficient because of what was learned from insulating space shuttles that were sent into space. Many advancements in technology have been linked to space travel.
Based on the phrase "another benefit mentioned,” how is home insulation connected to space exploration?
