== Launch ==
With the [[Cuban Missile Crisis]] unfolding, the USSR spacecraft ''Mars 2MV-4 No.1'' was launched at 17:55:04 UTC on 24 October 1962, atop a Molniya 8K78 carrier rocket flying from [[Gagarin's Start|Site 1/5]] at the Baikonur Cosmodrome.<ref name="LL">{{cite web|url=http://planet4589.org/space/log/launchlog.txt|title=Launch Log|last=McDowell|first=Jonathan|publisher=Jonathan's Space Page|access-date=29 July 2010}}</ref> The lower stages of the rocket performed nominally, placing the payload and the [[Blok L]] upper stage into low Earth orbit. When the Blok L ignited following a [[coast phase]], lubricant leaked out of the [[turbopump]], which consequently seized up and disintegrated.

== Designations ==
The designations Sputnik 29, and later Sputnik 22, were used by the United States [[Naval Space Command]] to identify the spacecraft in its [[Satellite Situation Summary]] documents, since the Soviet Union did not release the internal designations of its spacecraft at that time, and had not assigned it an official name due to its failure to depart geocentric orbit.<ref name="RSW"/><ref>{{cite web|url=https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=1962-057A |title=Sputnik 22|publisher=NASA NSSDC|access-date=28 July 2010}}</ref> A [[United States]] [[Ballistic Missile Early Warning System]] station in [[Alaska]] detected the debris from the launch, and initially identified it as incoming [[nuclear weapon|nuclear warheads]], since the launch had occurred during the [[Cuban Missile Crisis]].<ref>{{cite web|url=http://burro.astr.cwru.edu/stu/advanced/20th_soviet_mars.html |title=Soviet Craft – Mars |last=Mihos |first=Chris |date=11 January 2006 |publisher=Case Western Reserve University |access-date=29 July 2010 |url-status=dead |archive-url=https://web.archive.org/web/20131013211415/http://burro.astr.cwru.edu/stu/advanced/20th_soviet_mars.html |archive-date=13 October 2013 }}</ref>
