#Aurora and all that jazz over #Chicago city lights. #YearInSpace

This week started with a spacewalk on the @Space_Station and ended with the release of results about how spending a #YearInSpace can change the human body. Find out all this and more on this week's #SpaceToGround: https://youtu.be/nQIKv5QtABM pic.twitter.com/uyt8NwEBz1 https://twitter.com/NASA/status/1116734582689271810

LIVE NOW: Our experts are answering your questions about what happens to the human body when it spends a #YearInSpace. Head over to our @Reddit_AMA to ask questions about our yearlong study of the DNA of identical twin @NASA_Astronauts: https://www.reddit.com/r/IAmA/comments/bc42xt/we_are_experts_working_on_the_twins_study_to/ …pic.twitter.com/XV80e88miJ https://twitter.com/NASA/status/1116432150964965376

At 2pm ET: The landmark Twins Study brought researchers together to observe what physiological, molecular and cognitive changes happen to a human body from exposure to spaceflight hazards. Listen to what they learned from an astronaut's #YearInSpace: https://go.nasa.gov/2G46V6m pic.twitter.com/9YM1K9QfmT https://twitter.com/NASA/status/1116396681849864199

To understand the impacts of spaceflight, we compared changes in gene expression for identical twin astronauts - one who spent a #YearInSpace & one who remained on Earth.

It's #NationalSiblingsDay! Ever wonder what happens when a twin sibling is sent for a #YearInSpace? Join us April 10 at 2pm ET as we share results that compare astronaut @StationCDRKelly’s space-based changes to his earthbound twin @ShuttleCDRKelly.
