Premise: United States astronaut Sunita Williams, currently on board the International Space Station, has today broken the record for the longest unbroken space flight by a woman. At 5:47 a.m. UTC Williams passed the previous record of 188 days and four hours set by Shannon Lucid in 1996. This is not the only record Williams has broken. Earlier this year she set a record of 29 hours and 17 minutes for time spent by a woman on space walks.
Hypothesis: Sunita Williams has never been on a space walk longer than 30 hours.
