'''''မီယာအာကာသစခန်း''''' ({{lang-ru|Мир}}, {{IPA-ru|ˈmʲir|IPA}}; lit. ''Peace'' or ''World'') သည် ၁၉၈၆မှ ၂၀၀၁ အထိကမ္ဘာပတ်လမ်းကြောင်းအနိမ့်တွင်ရှိခဲ့သော [[ဆိုဗီယက်]](နောင်သော်)[[ရုရှား]][[အာကာသစခန်း]]ဖြစ်သည်။ ၁၉၈၆မှ ၁၉၉၆ထိ ကမ္ဘာပတ်လမ်းကြောင်းပေါ်တွင်တပ်ဆင်ခဲ့သော မီယာအာကာသစခန်းသည် ပထမဆုံးအာကာသစခန်းဖြစ်ပြီး ယခင်အာကာသယာဉ်များထက်အရွယ်ကြီးမားသည်။ Assembled in orbit from 1986 to 1996, ''Mir'' was the first modular space station and had a greater mass than that of any previous spacecraft, holding the record for the largest artificial [[satellite]] orbiting the Earth until its deorbit on 21 March 2001 (a record now surpassed by the [[International Space Station]]). ''Mir'' served as a [[microgravity]] [[research]] [[laboratory]] in which crews conducted [[experiment]]s in [[biology]], [[human biology]], [[physics]], [[astronomy]], [[meteorology]] and spacecraft systems in order to develop technologies required for the permanent occupation of [[Outer space|space]].
The station was the first consistently inhabited long-term research station in space and was operated by a series of [[List of Mir Expeditions|long-duration]] crews. The ''Mir'' programme held the record for the longest uninterrupted human presence in space, at 3,644 days, until 23 October 2010 (when it was surpassed by the ISS),<ref name="Mirrecord">{{cite news|last=Jackman|first=Frank|title=ISS Passing Old Russian Mir In Crewed Time|url=http://www.aviationweek.com/aw/generic/story_channel.jsp?channel=space&id=news/asd/2010/10/28/11.xml|newspaper=Aviation Week|date=29 October 2010}}</ref> and it currently holds the record for the longest single human spaceflight, of [[Valeri Polyakov]], at 437 days 18 hours. ''Mir'' was occupied for a total of twelve and a half years of its fifteen-year lifespan, having the capacity to support a resident crew of three, and larger crews for short-term visits.
