ISS orbit corrected

Aug 19, 2010
This August 16 NASA TV image shows astronauts (C) from the International Space Station (ISS) out on a third spacewalk to work on repairing a failed cooling system, the space agency said. The orbit of the International Space Station (ISS) was successfully corrected on Thursday, an official of the Russian space flights control centre announced.

The orbit of the International Space Station (ISS) was successfully corrected on Thursday, an official of the Russian space flights control centre announced.

The was raised by 2.2 kilometres to 355.5 kilometres (220.9 miles), the official said, quoted by Interfax news agency.

The manoeuvre was carried out using the engines of the Russian cargo vessel Progress M-06M.

The orbital correction was needed to provide the optimal conditions for the docking of Progress M-07M on September 10 and the departure shortly of another Russian vessel, Soyuz TMA-18.

The ship carrying Russian cosmonauts Alexander Skvortsov and Mikhail Kornienko and US astronaut Tracy Caldwell Dyson is due to return to on September 24, the official said.

I'd love to read an article about actually carrying out an orbit hike on the ISS.

There have to be a number of exotic and very difficult problems to overcome. For example, one would think a cargo vessel thruster would be way too strong for the job. After all, the ISS is built like a straw model, so it would bend and vibrate, or even break at several places, if thrusted too vigorously.

Attaching the vessel so that its thrusters point at the center of mass of the combined system should be a problem, too. And steering while thrusting should be a challenge, to put it mildly.

The more you know about statics, mechanics, and propulsion physics, the more you find the task overwhelming.
