Roscosmos has denied that the Breeze-M upper stage used to send ESA’s ExoMars mission to Mars malfunctioned.

Briefing reporters in Moscow, Igor A. Komarov reiterated statements made by Proton prime contractor Khrunichev Space Center of Moscow, saying the Breeze-M upper stage separated ExoMars without incident and then proceeded with the standard passivation and collision-avoidance maneuvers.

Komarov said he had seen photos taken from a Brazilian ground telescope that appeared to show small objects in the vicinity of the Breeze-M stage and ExoMars.

“I do have these pictures, provided by the Brazilian observatory, showing the ExoMars spacecraft surrounded by some dimly illuminated objects reportedly related to the upper stage,” Komarov said.

“Telemetry and other objectively verifiable data available to us, covering the entire time from the separation and the contamination and collision avoidance maneuvers to the passivation of the upper stage, show that all these steps have been performed successfully, without any anomalies,” Komarov said. “There is absolutely no indication of an upper-stage explosion or breakup.”
