MIAMI – A few spacewalking veterans set out on Tuesday morning in front of the International Space Station for the first of two planned spacewalks. NASA flight engineers Drew Feustel and Ricky Arnold emerged from the airlock at 7:30 am EST for a scheduled six-hour spacewalk. The task of the day: Moving a component called the Pump Flow Control Subassembly (PFCS).
This component controls and controls the flow of ammonia through the station's external cooling system. And with six people living there, 250 miles above the earth, nobody wants that all those components and electronics overheat.
Robotics engineers who do not travel in space are also involved in the mission. They control the large Canadarm2 and the Dextre robotic arm to place the PFCS on a carrier for further testing.
For Feustel, this is the eighth spacewalk of his career. It's his fourth for Arnold.
It is also the fiftieth spacewalk in the history of the International Space Station ISS. NASA astronaut Ricky Arnold on the left and NASA astronaut Drew Feustel on Wednesday, May 1
This Sunday, anyone living in the Boston area of Charleston has the opportunity to look outside to look up and, in good weather, to board the next freighter from Earth see. At 05:04 EST, Orbital will launch ATK's Antares rocket from NASA's launch site in Wallops, Virginia, and bring more than "7,000 pounds of research and science to the Space Station to support dozens of research and crews and hardware," said NASA.
These include the components needed for the second spacewalk in June.
The same astronauts, Feustal and Arnold, will again be doing the "outdoor work" and installing high-definition cameras on the Harmony module, which will make it easier for future commercial crew vehicles to align themselves with the international docking adapter.
Boeing and SpaceX plan to fly astronauts to the space station with both aerospace companies later this year. The first test flights – flying empty to prove they're healthy – in August.
Until next year, NASA will no longer have to rely on paying the Russian space program for $ 70 million
