Keywords

💡Spacewalk

A spacewalk, also known as extravehicular activity (EVA), is when an astronaut operates outside the spacecraft in the vacuum of space. In the script, the spacewalk is the central theme, with the astronauts conducting various tests and maneuvers outside the Dragon spacecraft, as indicated by phrases like 'first view from a helmet cam' and 'Jared now egressing through the forward hatch of Dragon'.

💡Helmet Cam

A helmet cam is a camera mounted on the astronaut's helmet to provide a first-person perspective during a spacewalk. The script mentions 'helmet cam' several times, emphasizing the first-person view of the astronaut's activities, such as 'looking out drag SpaceX we see installed ev1 is go to'.

💡Dragon

Dragon is a spacecraft developed by SpaceX, designed for carrying both crew and cargo to the International Space Station. The script refers to the Dragon spacecraft as the location of the spacewalk, with phrases like 'the hatch is open on Dragon' and 'first views of the first ever commercial spacewalk'.

💡EVA Suit

An Extravehicular Activity (EVA) suit is a specialized spacesuit designed to protect astronauts from the harsh conditions of space during spacewalks. The script alludes to the mobility and functionality of the EVA suit with terms like 'suit Mobility checks' and 'Dynamic and with disturbance'.

💡Resilience

Resilience is the name of the SpaceX Crew Dragon spacecraft featured in the script. It is the vehicle from which the astronauts perform the spacewalk, as mentioned in 'resilience are the first views of the first ever commercial spacewalk'.
