NASA Finds Space Travel Changes The Way Genes Are Expressed
NASA has been studying the Kelly twins — Scott, who spent a year in space, and Mark, whose body served as a comparison on Earth.

NASA's 2020 Mars rover will have more "eyes" than any rover before it.
NASA unveiled a detailed design for its newest rover, and it'll have 23 cameras. To put that in perspective, the Spirit and Opportunity rovers each have 10 cameras, and the Curiosity has 17.
But it's not just about the number of cameras — many are better quality.
The new rover's engineering cameras will be able to take 20-megapixel color images. That's far more detailed than the 1-megapixel black and white images captured by the Spirit, Opportunity and Curiosity engineering cameras.
Some of the new rover cameras will also have improved 3-D imaging capabilities.
Of course, the updated hardware comes with some challenges. Better imaging means there's more data to transmit through space.
Luckily, NASA says rover cameras have gotten better at compression.
The 2020 Mars rover is expected to launch in July or August of that year. The rover will look for habitable areas and signs of past microbial life and test oxygen in the atmosphere.
