When does NASA TV coverage begin?
Nice article--thanks Chris.Was the parking orbit really 300km away? That sounds far, but I honestly don't know...Question for those in the know: regardless of how far away the parking orbit, will the added manuevers impact the reboost portion of this vehicle's mission?Happy Fourth of July, United States!

Russian solar arrays are tracking the sun again
Along with the European Space Agency (ESA) ATV (Automated Transfer Vehicle) – preparing for its second launch later this year, and the Japanese HTV (H-II Transfer Vehicle) – also waiting to launch on its second mission next year – the ISS relies heavily on the Progress vehicles for critical supplies.With the expected loss of the massive upmass capability provided by the Space Shuttle via 2011’s retirement, and an ISS extension to at least 2020, problems with the Progress fleet would be a serious blow to providing the required supplies to enable of crew of six to be sustained on the orbital outpost.
apparantly they are talking about the video streaming station crashing.Windows froze and then crashed. The " sorry, we've crashed - want to send a report?" Ridicilous, that they're using that up there. But hoorrahh for a succesfull and pin-point docking.

Space-Pete,UKMy observation of ISS last night was of the Progress-M-05M vehicle and NOT the Progress-M-06M vehicle (which docked today).In UK , most observers viewing ISS will be looking southwards tracking ISS from west to east. The 'order' of flight of vehicles last night was (using US TLE data) Progress-M-05M followed by ISS then followed by Progress-M-06M.I was able to clearly see the Progress-M-05M (my earlier report) ,then ISS but could detect the Progress-M-06M vehicle.If it stays clear tonight - as it is now - then I should definitely be able to say I 'observed' Progress-M-06M - because its docked at ISS :-) Progress-M-05M should still be 'out front'
When they're ready to discard Progress M-06M, could they possibly have it perform some additional docking manouevers to help troubleshoot what went wrong? Or are they confident they've got it nailed down?
Question for those in the know: regardless of how far away the parking orbit, will the added manuevers impact the reboost portion of this vehicle's mission?
Friday's true miss distance....Press reports Friday said the Progress "missed the ISS by 2 km", even though we all here could see [on the screen-grabbed Kurs display] a pretty hot negative R-dot at the time that dynamic operations were terminated (at 2.4 km).This morning a press report clarified that indeed the post-abort trajectory took the Progress much closer to ISS but on a still-safe verified trajectory: 640 meters miss distance.Source: ITAR-TASS July 4 // 1811 gmt report, quoting Vitaliy Lopota.
"A commission is working on the cause of the unstable contact. We will definitely get to the source of the unstable contact within the next two weeks," said the president of the Energia rocket and space corporation, Vitaly Lopota.
Another sign they were just guessing is that they ALSO powered down the amateur radio rig in case IT might have been the source of the interference.
Was that last photo taken from Poisk?

Ah yes you're right. I should have payed more attention to the exposed facility on the far right -- that well constrains the point fo view.
due to noise, communication channel and the astronauts accidentally pressed one of the buttons on the control panel
With regard to its modernization in the Progress M 08-M "and" Progress M 09-M, Soloviev said that "we think of the evolution.
Accident commission of RSC-Energia completed investigation of the failure caused interruption of Progress M-06M rendezvous to the International Space Station on July 2, at 20:20:42.The commission concluded that the rendezvous failed due to unauthorized command "Dynamical mode abort" in the backup manual approach control loop of the Progress.The command was generated because of interference in the TORU metric wave signal link and pressed button "Operation" on the TORU panel in the ISS Zvezda module.To avoid similar situation in the future, relevant updates have been implemented for Progress M-07M slated for launch in Sept.For the next cargo vehicles to fly, additional blocking for this command has been introduced.
From ISS On-Orbit Status Report for 23/08/2010:Progress M-06M/38P Commission Report:According to the now published Russian Commission report on the aborted 38P rendezvous approach on 02/07, the failure was due to the KURS automated rendezvous & docking system's receiver (KURS-P) on 38P being shut down by an automatic emergency command when the transmitter on the ISS (KURS-A) was not activated at the same time as KURS-P (at 8 km). This caused the latter to receive only noise, resulting in an emergency shutdown. Subsequent activation of KURS-A then squelched the noise, allowing 38P to approach to 2.8 km, but the system still contained the emergency command which cancelled the standard KURS test planned at this point. 38P then flew by the ISS on its passively-safe flyby path (as per ballistic trajectory design), without requiring any abort burns. Two days later (04/07), 38P docked successfully to the SM Aft port under KURS autopilot control. To prevent noise from getting into the KURS receiver in the future, it will be activated much later, at 3 km (just before the test), and the transmitter at 8 km. The ground will also verify that KURS-P on Progress is receiving a strong signal, before the crew starts their steps. Also, in an unrelated issue, one of the three channels on the ISS-based command unit has an anomaly, and it will be replaced. For Progress M-07M/39P docking, this unit will be used in the two-channel configuration.
