Stay on target NASA Says 2 Asteroids Will Safely Fly By Earth This WeekendScientists Discover Possible Interstellar Visitor Warning: This video of the labyrinth International Space Station is not suitable for people with claustrophobia or motion sickness.Russian cosmonaut Oleg Artemyev takes Earthlings on a virtual tour of the International Space Station’s longest route: from the Japanese module at one end to the cargo truck at the other.The video—part Cloverfield shaky cam, part spellbinding travelog—escorts viewers along the longest pathway on the station.“Let’s go!” Artemyev says as he kicks off through the Japanese storage module, passing NASA’s Serena Auñón-Chancellor (“The best person on the station”) and Commander Drew Feustel (“the second best,” Artemyev jokes).In the team’s living quarters, he meets American astronaut Ricky Arnold and German scientist Alex Gerst. The walk-and-talk shot continues past power lines and the cafeteria, through a narrow hole and into the Russian section.The process of assembling the ISS began in the 1990s, with the Zarya and Unity modules. Russia’s Zvezda block was added in 2000, allowing a permanent crew of up to two astronauts.As more units were added over time, the Space Station now features 16 pressurized modules: five Russian, eight U.S., two Japanese, and one European. Another Russian component (Nauka) is scheduled for launch next year. Each new puzzle piece extends the artificial satellite, creating a playground for space explorers like Artemyev to show off.Without stopping, the cosmonaut crosses a storage module and service module, where work is in progress (presumably by final crewmember Sergey Prokopyev).“And here the longest route comes to an end,” Artemyev says, stopping himself on a piece of equipment like an amateur ice skater breaking on the rink wall. “[It] ends with our cargo truck, where we have stuff packed that will be sent burning into [the] atmosphere.”Artemyev regularly shares his cosmic experiences with fans on Twitter, Instagram, and YouTube (where the latest video was posted just 43 minutes ago). Last week, he showed viewers “the most important system on the International Space Station”: the toilet.Want more amazing space videos, like an astronaut photographing earth?
