Questions & Answers

Q: What is the main objective of the upcoming spacewalk?

The main objective is to replace a failed sequential shunt unit (SSU) that controls voltage and current on the ISS.

Q: How long is the spacewalk expected to last?

If everything goes smoothly, the replacement of the SSU should take about 15 minutes. However, additional tasks may extend the overall duration.

Q: What are the physical challenges faced by astronauts during a spacewalk?

Astronauts have to work in bulky spacesuits, which can make fine motor tasks difficult. The lack of gravity and the tight spaces can also make the work physically demanding.

Q: When will the International Docking Adapter (IDA) be installed?

The IDA will be installed in 2016, with the specific timing still being determined.

Summary & Key Takeaways

• Astronauts Scott Kelly and Mikhail Kornienko are nearing the end of their year-long mission on the International Space Station (ISS).

• The spacewalk will focus on replacing a failed sequential shunt unit (SSU) that helps regulate voltage and current on the ISS.

• Additional tasks include installing a non-propulsive vent and routing cables for the International Docking Adapters (IDAs).
