Reaching new heights! Today marks @Astro_Christina ’s 300th day in space. In December, Christina set the record for the longest single spaceflight by a woman, eclipsing the record of 288 days set by former astronaut Peggy Whitson. Her extended mission is helping us learn how to keep astronauts healthy for deep space exploration to the Moon and Mars. #CongratsChristina #NASA #Space #BreakingRecords #whoruntheworld
