Expedition 45 Commander Scott Kelly has been in space longer than any other NASA astronaut. Today he exceeds Michael Lopez-Alegria’s record of 215 days on a single spaceflight. He passed Michael Fincke’s record of 382 cumulative days in space on Oct. 16.

Kelly also completed his first spacewalk along with Flight Engineer Kjell Lindgren on Wednesday. The duo worked outside for seven hours and 16 minutes on a series of tasks to service and upgrade the International Space Station. They wrapped a dark matter detection experiment in a thermal blanket, lubricated the tip of the Canadarm2 robotic arm and then routed power and data cables for a future docking port.

Meanwhile, the crew is back at work today on advanced space science and routine laboratory maintenance. Japanese astronaut Kimiya Yui explored how plants grow without gravity to guide them. Kelly recorded his impressions of the space station’s living and working space for the Habitability study. Lindgren trained for the VIABLE experiment that researches microbe development on station surfaces.

The cosmonauts including Sergey Volkov, Mikhail Kornienko and Oleg Kononenko worked on scheduled tasks in the Russian segment of the orbital laboratory. They explored Earth photography techniques, the physics of plasma crystals and controlling a rover on the ground from space.

  1. Congratulations to you Mr. Scott Kelly . Well done Mr. Scott Kelly by exceeding Mr. Michael Lopez-Alegria’s record of 215 days on a single spaceflight and you passed Michael Fincke’s record of 382 cumulative days in space on Oct. 16.

  2. This is a huge moment for the program that I feel didn’t really get the attention it deserves, and Scott still has more time up there! The amount of research and technological developments required to keep a living human in space that long is remarkable, but what the developments will do for life here on earth is completely intriguing. It is common fact that many of the things we couldn’t live without, like my smartphone, find their roots in space programs and I’m excited to see what technologies will be the product of the year in space! it’s important to remember that while it’s cool that a record was broke, breaking the record was never the point of the mission.
