4. Untethered Spacewalk
Read the Question.
On a scale of 1 (not very anxious) to 5 (very anxious), how anxious do you think you would if you had to conduct an untethered spacewalk?
Scan the Blurb.
An untethered spacewalk required the use of a maneuvering unit to propel the astronaut in space and prevent the loss of an astronaut due to lack of gravity. This process was successfully attempted in the February of 1984 by the astronauts on STS-41-B.
