Answer:
Rovers
Explanation:
Rovers have been employed in the study of planets other than the earth. For example in 2003, NASA went on an exploration of the planet, Mars with the aid of rovers. Rovers are able to pick up information regarding the biosphere of other planets.
In 2014, NASA also reported the use of the Curiosity and Opportunity Rovers to study the Martian environment. So, rovers are an improvement in technology that can aid our understanding of other planets.
