Telemetry ceased to be received from the Progress spacecraft, which went to the ISS. The mission can be changed.
The Soyuz-2.1a rocket with a transport spacecraft on board was launched from the Baikonur cosmodrome at 10:09 Moscow time. The launch took place in the normal mode, but later the Mission Control Center reported that there were problems with telemetry - obtaining information about the values of the measured parameters. Malfunctions have already forced the MCC to postpone the docking with the station and transfer the mission to a two-day scheme.
Almost immediately it was suggested that the difficulties could be caused by the non-disclosure of the ship's directional antennas. We are talking about two of the six antennas with which the Kurs docking system is equipped. It is expected that the difficulty can be resolved by sending the additional data packet. Another MCC representative did not confirm the information about the unopened antennas, and the telemetry, according to him, is currently being received intermittently.
In honor of the anniversary of Victory in the Great Patriotic War, Progress M-27M is to deliver a copy of the Victory Banner to the ISS. In addition, he will bring scientific equipment, food, fuel and oxygen. The total weight of the payload is 2.5 tons.
Progress is not the only space truck capable of carrying out missions under the ISS program. In addition to him, HTV (Japan), as well as Dragon and Cygnus (USA) are used for these tasks.
