Vacuum suit: Difference between revisions

'''Vacuum suits''' are a form of protective suit used for [[extra-vehicular activity]] in outer space, intended to protect the wearer from the effects of vacuum and prevent asphyxiation. They also provide protection from dust and other particles which could damage the user and their equipment. Vacuum suits are completely sealed and come with an extra supply of [[oxygen]] (in the case of humans) or whatever other gas the user breathes.

The [[UNSC]] utilizes several types of vacuum suits.  

Bulky, black vacuum suits<ref>'''Halo: Contact Harvest''', ''page 126''</ref> with a compartmentalized design and [[Sealant foam|self-sealing foam]] injectors were used by [[Staff Sergeant]]s [[Avery Junior Johnson|Johnson]] and [[Nolan Byrne|Byrne]] during humanity's [[Skirmish on Minor Transgression|first combat encounter]] with the Covenant in [[2525]].<ref>'''Halo: Contact Harvest''', ''page 130''</ref>

{{Main|Black body suit}}

This body suit is a form-fitting suit of polymer body armor that has systems that mask the infrared signature of the wearer, as well as creating a comfortable environment. The suit is fully sealed, and has an oxygen reserve of 15 minutes. The helmet has encrypted communications gear and a HUD, along with thermal sensors and motion detectors. Unfortunately, the suit's general complexity leads to complications. Over prolonged periods of time the suit will become very uncomfortable to wear, and is difficult to repair in the field.<ref>'''Halo: The Fall of Reach''', ''page 79''</ref>

These suits were used by the [[SPARTAN-II Program|SPARTAN-IIs]] in several missions before they got their [[MJOLNIR Powered Assault Armor/Mark IV|MJOLNIR Armor]].

The [[MJOLNIR Powered Assault Armor]] system utilized by the [[SPARTAN-II Program|Spartan-IIs]] has 90 minutes of breathable atmosphere.<ref>'''Halo: The Fall of Reach''', ''page 120''</ref> The vacuum capabilities of the armor were demonstrated during the initial phase of the [[Battle of Earth]], where [[John-117]] utilized the armor effectively in vacuum combat. As well as being completely sealed, the armor can prevent the [[SPARTAN Program|wearer]] from burning up in a planet's atmosphere. Later in the [[Battle of Earth]], Spartan-117 fell through the [[Earth]]'s atmosphere into the jungle of [[Kenya]], and survived, although he did use a part of the [[Forerunner Dreadnought]] as a heat shield.<ref>'''[[Halo 3]]''', campaign level ''[[Arrival]]''</ref><ref>'''Halo 3''', campaign level ''[[Sierra 117]]''</ref>

The most common version of the [[ODST armor|suit of combat armor]] worn by the [[Orbital Drop Shock Trooper]]s is fully vacuum-sealed and includes oxygen reserves for 15 minutes.<ref>'''Halo: The Cole Protocol''', ''page 56''</ref> However, some variants of the armor leave the neck and fingers exposed and are thus not rated for vacuum operation.<ref>'''Halo 3: ODST'''</ref>

The [[Covenant Empire|Covenant]] also use vacuum suits,<ref name="Reach">'''[[Halo: The Fall of Reach]]''', ''page 310''</ref>  such as the blue-and-black suits worn by [[Kig-Yar Ranger]]s. [[Sangheili Ranger]]s and other special operations units utilize special vacuum-enabled [[Sangheili Combat Harness|Combat Harnesses]], such as the [[Assault Harness]], [[Flight Harness]], [[Ascetic Harness |Ascetic Harness]] and [[Commando Harness]].
