Editing Phobos 1 (section)

== Flight plan ==
It was to take an estimated 200 days for the ''Phobos 1'' space probe to travel from the [[Earth]] to Mars. Two mid-course corrections were planned, the first between days 7 and 20, and the second between days 185 and 193. These corrections would place the probe in a highly [[Elliptic orbit|elliptical orbit]] around Mars. Next, it was to move into an almost circular observation orbit at 350&nbsp;km. After achieving observation orbit the lower stage of the propulsion system would be dropped. The probe would then rendezvous with Phobos, drop a lander containing scientific equipment from an altitude of 50 meters, and move into a final [[Non-inclined orbit|equatorial orbit]] above Mars where it would study the Martian surface and atmosphere.<ref>{{Cite book|title=Russian Planetary Exploration|last=Harvey|first=Brian|publisher=Praxis Publishing|year=2007|isbn=978-0-387-46343-8|location=Chichester, UK|pages=246–248}}</ref>
