On January 5, 2016, 56-year-old American astronaut Peggy Whitson arrived at the International Space Station and became the oldest woman in space. That breaks the record of fellow American Barbara Morgan, who was 55 when she went into space in 2007, though it's still a far cry from the oldest man: John Glenn, who in 1998 went to space for the second time at the ripe old age of 77.
But that's not the only record Whitson broke. A day after her arrival, she became the oldest woman to perform a spacewalk. By the end of her six-month mission, she's also likely to break the record for the longest time any American has been in space (Jeff Williams' 534 days) and perhaps for the most spacewalking (she's 10 hours shy of Sunita Williams' 50 hours).
