The communications pass will give engineers confirmation the spacecraft is healthy following launch, and officials also hope to verify the extension of the orbiter\u2019s power-generating solar panels.<\/p>\n<p>Often used to propel communications satellites into high-altitude orbits thousands of miles above Earth, the Proton\/Breeze M combo has flown 87 times since 2001. The Proton\u2019s core booster has been flying since 1965, amassing 410 missions launching commercial and Russian military satellites.<\/p>\n<p>But the launcher\u2019s track record in recent years has been spotty, at best, with six failures of the Proton rocket or its Breeze M upper stage logged in 49 flights since December 2010. The Proton\/Breeze M has a run of six straight successes since its last mishap in May 2015.<\/p>\n<p>Two of the recent failures were blamed on a design flaw in the Proton\u2019s third stage \u2014 a weakness that Russian officials say has now been corrected \u2014 and investigators identified quality control issues for other in-flight anomalies.<\/p>\n<p>\u201cESA got a report of the last failure and all the measurements they have taken, and they are strongly committed to not allowing this to happen again,\u201d said Walter Cugno, ExoMars program manager at Thales Alenia Space, the mission\u2019s primary European contractor.<\/p>\n<p>Russia has a star-crossed history with launches of Mars missions, with the last two attempts never making it out of low Earth orbit.<\/p>\n<p>European space officials switched the ExoMars launches to Russian Proton rockets after NASA withdrew from the program in 2012 due to funding restrictions within the agency\u2019s planetary science budget.<\/p>\n<p>NASA originally signed up to launch the 2016 and 2018 missions aboard Atlas 5 rockets from Cape Canaveral.<\/p>\n<p><b><i>Email the author.<\/i><\/b><\/p>\n<p><em><strong>Follow Stephen Clark on Twitter: @StephenClark1.<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Artist\u2019s concept of the Proton rocket\u2019s payload fairing releasing in flight, revealing the ExoMars spacecraft.
