After being delayed on account of attainable hazard from house particles, astronauts aboard the Worldwide Area Station (ISS) went for a stroll in house to restore a defective antenna.
Astronauts Thomas Marshburn and Kayla Barron have been given the go forward to finish a spacewalk that was initially scheduled for November thirtieth. NASA made the choice to delay the spacewalk on account of a attainable hazard of house particles and to provide them time to evaluate the chance. It was unknown on the time if the house particles that was in query had been remnants from the Russian ASAT that destroyed a Russian satellite tv for pc lately.
Dana Weigle, NASA’s deputy supervisor of the ISS, acknowledged on the time of the delay that the chance to astronauts was inside what she known as “regular atmospheric fluctuations and the traditional quantity of particles that strikes via.” She added, “What it actually tells us is EVA (extravehicular exercise) has all the time been dangerous.”
The spacewalk and restore of the defective S-Band antenna is being broadcast stay on NASA TV and through NASA’s YouTube channel (which will be watched under). It began at 7:10am ET and can final round six and a half hours. Test it out…
The spacewalk is Barron’s first and Marshburn’s fifth in addition to the station’s 245th spacewalk in help of meeting, upkeep, and upgrades. The 2 astronauts arrived to the ISS aboard the SpaceX Crew Dragon capsule on November eleventh. The 2 astronauts had been assisted in making ready for the spacewalk by fellow astronauts, Raja Chari and Mark Vande Hei.
The 2 shall be working on the Port 1 truss construction, the place the antenna in query is mounted. The antenna lately misplaced capability to ship alerts to Earth through NASA’s Monitoring and Information Relay Satellite tv for pc System. Regardless that the antenna’s points had restricted influence on ISS operations, the choice was made to go forward and handle the issue to make sure communications redundancy. Along with the S-Band antenna that’s being repaired, there’s additionally a low-rate-S-band system, in addition to a high-rate KU-band communication system that sends again video.
