Just a heads up: Docking to the SM Aft port will occur today at 4:58 PM GMT.
-
Earth view from ISS
-
ISS and Progress M-06M are over the Atlantic Ocean
-
Uh-oh: Seems like TsUP-M have lost telemetry from the Progress.
-
-
Russian Mission Control Center
-
Apparently they lost Kurs signal on the Station side, but Progress is being seen receding from ISS and rotating, according to what they can see from the windows.
-
Skvortsov reporting that Progress is moving away from the station.
-
About to pass over Russian ground stations, that is expected to provide additional info about the situation.
-
NASA ISS Tracking, docking time: 08:58 p.m. Moscow
-
No visual indication of Progress right now, presumed to have flown ahead of them (I suppose that means aft)
-
this is the only image from Russian MCC
-
View from Progress:
-
I can't see the ISS
-
If the Klest TV signal is being received, the implication is that TsUP is also receiving telemetry.
-
Another camera on Progress or view from Zvezda?
EDIT: Confirmation it's from the wide angle camera in Progress.
-
-
Range 3 km as seen from ISS.
800 mm lens used from window 9 on ISS, Progress seen as a dot from that vantage point.

That works out to an optical magnification of 13.76x (like looking through binoculars of that power).
-
Is the Progress camera, you can see the name "Прогресс"
-
I just tuned in to NASA TV expecting to see Progress a few meters from the SM Aft port....and they lost signal with Progress, and it flew right by the ISS?! We're just lucky we didn't have a collision, like the one on Mir!
-
Into orbital night now.
Past the time of the expected docking, obviously.
-
Deactivating Kurs (TORU was deactivated earlier), so it appears we won't get another docking attempt soon.
However, the ISS' attitude will be kept for another revolution to keep options open.
Past Russian ground stations now.
-
Not possibility for collision like Mir, Progress is in safe distance
-
Progress docking aborted
-
Doesn't look like there will be another docking attempt today.
-
Phasing and orientation-derived power concerns are making it clear docking will have to wait. Also, time is needed to investigate what caused the telemetry lock loss.
-
When was the last time that happened?
-
ISS tracking and live picture from ISS
-
Awaiting word from Solovyov (Russian flight controller) as to the definitive course of action, although no-go for docking appears the most probable outcome for today.
-
Time to unstow the TORU equipment (actually, its already been prepped, as this is a normal op for Progress dockings).
The larger issue is why the new Progress series keeps failing.
-
Progress is in safe distance of about 3 km.
Docking cancelled for today
EDIT: another picture from ISS, Progress flying "near" the complex

Thanks.
"Nice" to get to see a contingency put into work. Good training.

but the other abort was the collision to Mir in 1997, this event was a abort or just a fail during docking?
-
two more views from ISS

First of all that was a re-docking attempt and secondly I don't think it counts as an abort anyway.

There are different flavors of aborts for a Progress docking, depending on the situation. For example, if there is a problem with, say, Progress telemetry, a docking attempt may be halted at a great distance from ISS, or even a day before the planned docking. The "halt" would be accomplished via a command from TsUP.
Once Progress is under control by Kurs, a docking may be aborted simply by turning off Kurs, which can be accomplished by TsUP or the ISS crew.
Lastly, if Progress is under control by TORU, the abort is generated by the ISS crew.
At 3 km distance from ISS, Progress is under control of Kurs, and I suspect that TsUP commanded the abort.
Lastly, AFAIK, Progress does not have to be over a Russian ground station for TsUP to control Progress during dockings, the Russian segment can communicate with TsUP via TDRS.
-
Sorry, that's the moon, not Progress.
I don't think so, is not a good view because was during a zoom, if I am wrong, plis forgive me
-
No, it was the moon. When the iris closed down just before the end of the shot you could see it was the quarter moon. They haven't found the Progress with the cameras yet.

You're doing very well. I can't get any decent screenshots (VLC fails with the NASA stream lately). We can work out what is what as we go along. Good work!
-

I don't think so. I think that TDRS allows only voice transmission for Russian Segment, and that they have to fly over RGS to send telemetry.

Resupply Craft Docking Aborted
Mission controllers will not re-attempt to dock the ISS Progress 38 resupply ship to the International Space Station today. The station is being reconfigured for normal operations. The flight control team is in the early stages of diagnosing what may have caused the aborted docking with the space station.
Future docking opportunities are being evaluated. The Progress vehicle is in a safe configuration well away from the space station. The crew was never in any danger.

I don't think so. I think that TDRS allows only voice transmission for Russian Segment, and that they have to fly over RGS to send telemetry.
AFAIK, there was a mod to the Russian segment/USOS to provide for TsUP command/control of Progress, apparently happened within the last 2 years. This allows for dockings away from Russian ground stations, which previously had been a program constraint.
I noticed such dockings in the last year, and someone here informed me in a post of the mod.
-
I'm trying to reconstruct the relative motion of this abort and some things are bothering me.
TsUP-M says the abort was declared at a range of 2 km, which is short of the 'stop' point where the vehicle then makes a constant-range fly-around to align with the docking port approach vector.
Press reports also state that the crew tried to engage TORU but were unable to achieve control -- the vehicle never acknowledged their commands.
I seem to recall that the automated approach emergency modes included stopping the approach and initiating a backaway if no commands are received.
But from the TORU screen it looks like the vehicle had a 7-9 m/sec approach rate and never nulled it -- kept right on going in, missing the station -- but by how much?
-

According to the same screen, 2.777 km.

I agree JimO--the fact the vehicle continued on past the station is a bit unnerving. I'm not declaring "It almost crashed!", but this does seem like a very interesting event.
Now if the vehicle is splashed, or worse, doesn't dock with no further info, then we can begin to really wonder...

Progress will automatically set itself on an evasive course from ISS if the docking aborts. In this case it flew past the station, at a safe distance, and put itself in a contingency orbit with a slight opening rate relative the station. The fact that the Progress didn't stop itself dead in its tracks and back away (a' la ATV) doesn't mean there was ever a danger of a collision or that the craft was "out of control". It always knew where it was in space. The evasive maneuver's trajectory depends on a number of factors and it takes a lot less propellant to divert the "forward" trajectory and fly past the station that it does to stop completely (relative) and spend more propellant backing away. If too much propellant gets used up in such a situation, then Progress could end up fish food.
But a very interesting day.
-
Makes sense--and good stuff. Thanks landofgrey...
-
if there only was good easy-to-understand simulation videoes of different modes, this would be more easy to explain to the general public (read: friends.)
Thanks landofgrey for your explanation :)
-
According to the same screen, 2.777 km.
[/quote]
But doesn't the same screen show a large negative R-dot at the same time? So the final 'closest point' will be considerably less.
Who can help -- remember the schematic of typical 'Progress' rendezvous maneuvers? Where did we see it?
My information is now that the abort was called before the final braking burn was performed, which also targets a direct approach to the ISS [prior to the burn, as a safety measure, there is a substantial offset of closest approach].
Without that burn, the trajectory is automatically 'fail safe' and no further avoidance maneuvers would have been required, exactly as several very well informed observers advised us.
But it still has a pretty hot approach rate for a minute or two even with a guaranteed miss distance.

Hi,
I managed to capture the M-06M with the telescope just a few hours after launch, and its rocket;
http://www.startje.be//vieuw.php?qid=347203
I'm just comming in from observing the Progress after its docking abort from today. The Progress was flying about half a minute preceding the ISS. Imagery in poor seeing, results later.

The Progress was flying about half a minute preceding the ISS.
That would indicate on the order of 150 miles of separation, I think.

From www.nasa.gov/station:
Russian and US ISS program managers will meet the morning of Saturday, July 3 to assess the next docking opportunity, preliminarily identified as approximately 4:17 PM GMT on Sunday, July 4.

-
Reading some very interesting comments and insights in this thread, I have some questions about the TORU screen: The screenshots that have been posted in this thread earlier on pages 3 and 4 all seem to have been taken at different times (at least the time indication in the top right corner is always different), but the rest of the parameters are always the same, e.g distance and Rdot, as if they froze. Shouldn't they be changing over time? Did the parameters freeze because of the loss of telemetry? If so, is there any indication, like a "caution" message, on the screen that telemetry has been lost and the parameters froze (apart from the fact that the parameters actually ARE frozen). Also, how could the controllers know by how much distance the Progress actually passed the ISS?
-
Regarding issue of whether Russians can get Progress TM through TDRS, this RIA Novosti story addressed the question squarely:
A deputy chief of the Russian Federal Space Agency Vitaly Davydov said that the cargo spacecraft would resume docking with the ISS on Sunday. "The docking is tentatively scheduled for Sunday. The docking will be carried out in the automated mode," Davydov said.
"The orbit currently occupied by Progress s/c does not allow to control its [spacecraft's] flight and get the telemetric information from the Russian ground tracking stations, and [to get the information] from U.S. tracking stations is unreal," Davydov said, adding it would take at least 1 day to assess the situation. He added the ISS's cosmonauts had not received further directions.
-
What would be the last-last-last measure to be taken if a Progress happened to deviate from its "safe" approach trajectory in just such a manner that it pointed straight at the ISS, and all on-board and remote control efforts failed?
Boosting the ISS orbit to take evasive action?
-

Brace for impact, after preparing as much as possible for depressurization, loss of control and evacuation.
Boosting the ISS orbit to take evasive action?
Not likely, ISS is too massive to get out of the way, even if it could commanded it in time. From a recent status report http://www.nasa.gov/directorates/somd/reports/iss_reports/2010/06052010.html
a one-burn ISS reboost was conducted last night at 11:20pm EDT using SM main propulsion, i.e., its two main engines. Performance was nominal. Burn duration: 4 min 7 sec; delta-V: 4.5 m/s
Those are pretty much the largest engines available.

I'm sure there is plenty of food, but what would happen with the EVA's or other planned launches ??

I haven't been able to find a detailed cargo manifest for this latest Progress. As a starting point, from a recent ISS On-Orbit Status Report, the Progress M-06M vehicle:
carries 2230 kg (4916 lbs) of cargo, specifically: 870 kg (1918 lbs) propellants, 50 kg (110 lbs) oxygen & air, 100 kg (220 lbs) water and 1210 kg (2667 lbs) spare parts & experiment hardware.

Reports that Progress was "rotating in an uncontroled manner", then it passed the station and moved ahead of it.
KURS did not fail. It was turned off by the automatic control system.
There has been a working group formed that conducts the analysis of the current situation.
Still enough resources on board to perform another attempt of approach and docking on Sunday.

From www.nasa.gov/station:
International Space Station Program officials from NASA and Roscosmos met Saturday morning and agreed to proceed toward a second docking attempt for the ISS Progress 38 cargo ship on Sunday, July 4, at approximately 12:10 PM EDT/4:10 PM GMT. They will meet again Sunday morning to reconfirm the status of the space station and spacecraft systems. NASA TV coverage of the second docking attempt for the Progress 38 cargo ship to the station will begin Sunday at 11:30 AM GMT/3:30 PM GMT.
The Progress 38 conducted two successful firings of its engines Friday night to put the craft in a parking orbit around 300 kilometers from the space station. Another engine firing is being conducted Saturday morning to start the process of returning the spacecraft back to the station for Sunday’s docking attempt.
Russian specialists told program officials the cause of Friday's aborted docking was what they termed a "cancel dynamic operations" command that instructed Progress' computers to fly the vehicle past the station on its final approach for docking, as it is intended to do if the internal guidance system receives conflicting commands or commands that do not comply with its pre-programmed commands.
The Russian flight controllers said the command to cancel was caused by the activation of the TV transmitter for the TORU manual rendezvous system in the Zvezda Service Module, which interefered with the Kurs automated rendezvous system. TORU is used to override Kurs, which Progress normally uses for docking, in the event Kurs experiences a problem. The TORU TV system is designed to provide a view of Zvezda's docking target to station Commander Alexander Skvorstov, if he had to operate a joystick in the service module to dock Progress manually.
The Russian flight control team has confirmed the Kurs system operated normally and did not fail, as was initially believed. Kurs uses radio beacon signals beamed back and forth between the approaching spacecraft and the space station to measure distance between the two vehicles and the rate of closure by Progress to Zvezda.
Russian officials said the TORU system will not be activated Sunday for the second docking attempt as a precautionary measure and expressed full confidence Sunday’s docking can be conducted without any further issue.
Overnight, Russian specialists conducted a successful test with both the prime and backup strings of the Kurs automated rendezvous system on both the Progress and Zvezda. Another test of both strings will be conducted Saturday night. A final test of the Kurs system, as is always conducted during the terminal phase of the rendezvous, will be performed about 50 minutes prior to docking when Progress is 15 kilometers from the station.
In the unlikely event the prime Kurs string of telemetry fails late in the rendezvous sequence on final approach, Kurs' backup string will take over through docking. If the second string should fail, an automatic abort would be triggered, and Progress would immediately halt its approach and back away from the station to a safe distance. Multiple docking attempts could be made if needed.
The Expedition 24 crew members onboard the space station were notified by the team in Mission Control in Houston that another docking attempt will be made Sunday. They have an off-duty day Saturday and will adjust their workday schedule to monitor the docking activities Sunday.
-
What we'll do - due to the added interest - is likely start a new thread for the second docking attempt.
I'll have an article on early Sunday for the attempt, given we've got some good internal info via L2, which I'll obviously include in the article.

From ISS On-Orbit Status Report for 03/07/2010:
Progress Update:
Progress M-06M/38P will make another rendezvous & docking attempt tomorrow (04/07) for Contact at ~4:17 PM GMT. [During yesterday's rendezvous, the automated KURS rendezvous sequence was aborted (cause currently under assessment) by the Progress MCS (Motion Control System) between two nominal burns (Impulse-4 & Impulse-5). 38P did not perform any abort burns since it was on a passively-safe flyby path from the outset (as per ballistic trajectory design). The vehicle performed two burns last night (02/07), one at 7:28 PM GMT (DO4) of 1.61 m/s delta-V, the other at 9:27 PM GMT (DO5) of 4.77 m/s. A third maneuver is planned for today in order to set up the proper trajectory conditions for tomorrow's docking attempt, for which ISS will be in the same configuration as for yesterday's docking (same attitude, same solar array & radiators positions).]
-
So far as I can tell, the chronological order of events that caused the abort was as follows:
• The TORU TV transmitter in the SM was activated by the crew, which
interfered with the data being sent between the KURS-A on
Progress and the KURS-P in the SM.
• The KURS-A on Progress interpreted this interference as conflicting
commands to its pre-programmed commands, and so initiated the
"cancel dynamic operations" command that instructed Progress to fly
past the ISS.
The only question that remains is: Who turned on the TORU TV transmitter? :o

Progress and the KURS-P in the SM.
• The KURS-A on Progress interpreted this interference as conflicting
commands to its pre-programmed commands, and so initiated the
"cancel dynamic operations" command that instructed Progress to fly
past the ISS.
The only question that remains is: Who turned on the TORU TV transmitter? :o
How does one say in Russian..."Hey, don't TOUCH that!"

I'm not sure, but I think it was Skvortsov.
But I don't understand it, wasn't he supposed to turn it on?
-
The correct question is: why this interference?
The Toru TV system has to be turned on in case of the need of an emergency Toru use if Kurs failed.
In order to prevent a new interference and repetition of the flyby action, the Toru will not be in standby during the next attempt. This procedure has the inconvenient that the crew could not proceed with a manual (Toru) rendezvous if the automatic mode (Kurs) fails.

Had a good visual observation of ISS (9807A) and the Progress-M-05M (10018A) at around 21:55 GMT from UK for about 6 minutes of this lengthy pass.
The ISS was 'spotted' first - cannot really miss it ! - but then noticed,in front of ISS,was the "much dimmer" Progress-M-05M freighter.
Could not make out any other vehicles associated with ISS at that time.
Unfortunately, looks like inclement weather tonight will stop any visuals from my location here in UK .
The attached image shows the predicted path of the two vehicles at time of observation and what the 'visual' was like for me.
At time of prediction (21:57:40 GMT) the ISS was predicted to be about 510 km from my site at an azimuth of 141 deg 37.667 min and altitude of 43 26.970 while the Progress-M-05M was at 572 km away and at azimuth 132 deg 55.910 min and altitude 37 deg 10.275.
Have had some spectacular views of ISS this last week or so with great co-operative weather (for a change) in UK ! With ISS being in 'constant sunshine' last few days visuals have ben great !

Apollo-phill: I too managed to see Progress M-06M & the ISS flying formation last night! They went into cloud pretty quick, but seeing two spacecraft in the same view always takes my breath away! :D

Latest via memos on L2 is the planned docking time is GMT 185/16:17 GMT.

Vehicles are coming off the coast of Africa.

Director of Flight for the Russian segment of ISS, Vladimir Soloviev said:
"The commission [FROB] have completed its work. () The reasons are two: 1. excess noise in the UHF channel and 2. a cosmonaut accidentially pressing a button."
He added that he is not gong to blame the cosmonaut because the button was not well protected from accidential pressing.
(adding from myself: reason #2 came first and aborted the automatic approach, reason #1 prevented manual take-over; also, waiting for Mr. Oberg's reaction LOL)

Progress M-06M is to Undock on August 31
27.08.2010
Progress M-06M / International space station (ISS) attached mission is almost over. ISS-24 crew finalizes accommodation of the items to be disposed of in the vehicle.
On August 31, at 15:19 Moscow time, an undoking command for the automatic cargo vehicle will be issued from the ISS. Three minutes later the Progress will be separated from the docking port on the Zvezda module. The vehicle has been docked to this port on July 4.
After separation, the Progress will continue flying autonomously. During this autonomous mission, Radar-Progress technical experiment is to be carried out.
Progress M-06M is to be deorbited over the remote area of the Pacific on Sept. 6.

Roscosmos PAO: "Astronomers in Irkutsk Monitor Autonomous Mission of Progress M-06M".
On August 31, Progress M-06M undocked from the International Space Station. Its autonomous mission will last until Sept. 6, with the purpose to conduct space experiment Plasma-Progress. Physicists of Irkutsk will monitor the autonomous mission of the vehicle to record Progress' maneuvers and to investigate ionosphere response to operations of its thrusters.
A powerful radar for these studies is located about 100km from Irkutsk, installed by the RAS' Institute of Solar Physics. Other Russian ground observatories and optical telescopes will also record maneuvers of the Progress.
