MCC has raised the ISS orbit at the second attempt
In the 1st time scheduled correction of the orbit of the International space station has not happened due to the fact that the engines of Progress M-26M" does not work to include in the estimated time under not clear circumstances.
Another attempt was successful - the average altitude of the station increased 2.8 kilometer.
After a string of technical failures and interruptions of the Federal space Agency (Roscosmos) were able to take the situation under supervision. The mission control center with the 2nd attempt turned out to raise the orbit of the International space station less than 3 miles.
"In accordance with the project ballistic support of the flight International world station on 18 may 2015, the recent adjustment of its orbit," - said the press service of Roscosmos. "Motors transport cargo spacecraft "Progress M-26M were introduced in 03:30 and worked 1922 seconds. The result of the execution of the maneuver, the average altitude of the station increased by 2.8 kilometers," - said the Agency.
When you first try adjusting the orbit space truck motors in the estimated time to include failed. The circumstances of the incident to find out. "The fact that the engines of "Progress" is not running at a certain time, the Russian MCC announced North American employees with Houston. Orbital corrections has not happened. Experts examine the circumstances do not start the engines", - quotes RIA Novosti source in the space sector.
"According to early reports, no evidence of the possibility of introducing space truck motors. This whole procedure prior to the start of the motors. It is likely, that the question of the concept of management. More while not to mention, you need to explore telemetric information," he added.
This is not the 1st problem that met domestic space area for 3 weeks. In April had an emergency with the "Progress M-27M", may 16, failed to carry out a reboost of the ISS was lost satellite MexSat-1. Satellite Kondor-e created for South Africa, also did not managed to boast a fully real job. With the correction of the ISS orbit, albeit with a 2nd attempt, however, to make happen.
