Extra-vehicular activity: Difference between revisions

[[Vacuum suit|Pressurized suits]] are a necessity during EVA operations due to the vacuum of space. In addition, [[thruster pack]]s are needed for maneuvering when not tethered to a spacecraft. Combat EVAs pose a significantly greater risk to those performing it, due to the chance of suit decompression in the vacuum if hit by bullets, shrapnel, etc. [[Civilian]] welders and technicians perform EVAs in order to repair ships, such as that performed upon the {{UNSCShip|Gettysburg}} in the [[Eridanus system]].<ref name="fs">'''[[Halo: First Strike]]''', ''page ??''</ref> The UNSC also employs specialized [[EVA Engineers]] on their warships such as the {{UNSCShip|Spirit of Fire}}. Specialized zero-G vehicles are also used to perform EVA, such as the [[Open Frame 92/Extra-Vehicular Activity]].<ref>'''[[Halo Legends]]''', ''[[The Package]]''</ref>

The [[Summa Deep Space Incident]] sparked multiple projects related to research of EVA equipment, including the [[MJOLNIR Powered Assault Armor/V variant|MJOLNIR EVA variant]], designed for better Extra-Vehicular Activity performance.<ref>'''[[Halo 3]]''', ''in-game [[armor permutations (Halo 3)|armor permutation]] description''</ref>

The [[John-117|Master Chief]] has performed four known combat EVAs: At the [[Battle of Chi Ceti]] in [[2525]], he inserted into a [[Covenant Empire|Covenant]] [[Unrelenting|warship]] with [[Kelly-087]] and [[Samuel-034]], planted a missile warhead and extracted him and [[Kelly-087]]; At the [[Fall of Reach|Battle of Reach]], in [[2552]], he performed another EVA in order to purge [[UNSC Circumference|a ship]]'s NAV database on an [[gamma Station|orbital station]] in accordance with the [[United Nations Space Command Emergency Priority Order 098831A-1|Cole Protocol]].<ref name="for">'''[[Halo: The Fall of Reach]]''', ''page ??''</ref> He performed another aboard the ''[[Ascendant Justice]]'' while in an anomalous slipspace dimension,<ref name="fs"/> the first known [[slipstream space|slipspace]] EVA and another at [[Earth]], clearing hostiles off the outside of the [[Cairo Station|Cairo]] [[Orbital defense platform|Orbital Defense Platform]] and removing and repurposing a Covenant Bomb.<ref name="h2">'''[[Halo 2]]''', [[campaign]] level ''[[Cairo Station (level)|Cairo Station]]''</ref>

The Covenant also perform EVAs. [[Sangheili Ranger]]s use specialized vacuum-sealed armor to protect themselves from the effects of a vacuum environment, in order to plant [[antimatter charge]]s and support boarding parties.<ref name="h2"/><ref name="for"/> [[Kig-yar Ranger]]s in vacuum suits were also used, though their suits were more easily damaged than Elites due to the fact they lacked a personal [[Energy shielding|energy shield]].<ref>'''[[Halo: Contact Harvest]]''', ''page ??''</ref><ref>'''[[Halo Wars: Genesis]]''', ''page ??''</ref>
