Solar panels of the space truck «Progress MS-09» checked on the Ground to avoid possible problems during its flight to the ISS.

«The tests included the disclosure of solar panels and inspection, followed by irradiation with a special light with control the amount of current in the onboard cable network of the ship, which confirms the integrity of the circuits and the performance of the most important elements of a power system, «Progress MS-09», — stated in the message of Roscosmos.

The launch of transport cargo vehicle «Progress MS-09» carrier rocket «Soyuz-2.1 a» from Baikonur is scheduled for July 10, 2018.

As previously reported, one of the early transport ships «Progress MC-04», crashed on the evening of 1 December 2016 on a deserted mountainous terrain in Tuva. According to cyclogram flight at the truck revealed a navigation antenna, but did not unfold solar panels, which was confirmed by the commentator of NASA in the Moscow mission control Center.

In addition, experts were forced to change the design of the mounting bracket of solar after of manned spacecraft «Soyuz TMA-17M», launched to the ISS in July 2015, it was revealed their jamming. It was found that when a certain pressure change during the launch of the mounting brackets of solar panels can by 0.8-1.5 mm, to change their position. Tests on Earth have shown that it is possible to a slight jamming. At the conclusion of the Commission such jamming can occur not always, but decided on the finalization of the design, which was done.
