NASA astronaut Scott Kelly returned to Earth Tuesday night after spending a historic year in space, setting the U.S. single-trip record, a trip he documented on social media.
Kelly gave a speech after he returned to Houston.

The veteran astronaut commanded the International Space Station during his 340 days above Earth.
Kelly and cosmonaut Mikhail Kornienko ran a number of experiments designed to test the effects of long-term space travel on the human body. Scott and his brother Mark Kelly, a retired astronaut, were chosen for the experiment since they’re twins and thus provide more useful data than two unrelated people.

Kelly flies home to Houston on Wednesday, where he will be greeted by family and friends, including Dr. Jill Biden.
