Spacewalk
It is a term used to
describe a trip taken by astronaut outside a spacecraft when it is in space.
Also called ‘EVA’,
an acronym for Extra-Vehicular Activity, or ‘moonwalk’ if the craft is on lunar
mission.
Spacewalk is
undertaken in order to perform various tasks. For example, astronauts conduct
science experiments in space to study how the space environment affects
results.
They repair
satellites while they are in orbit, preventing the need to bring them back to
Earth and also test new equipment.
