Based on recent thermal analysis, the propulsion tanks will take from 65 to 308 hours, depending upon current temperature and how many heaters circuits can be used, to warm the hydrazine in the tanks to 2 deg C. As power is available now, the secondary propulsion tank heaters (~30W) have been enabled. Also, selected power switching boards were powered off to prevent unwanted loading in preparations for powering on the avionics. To allow for sufficient time for procedure testing and review, the powering on of the avionics has been moved to the second track on Friday.

BEHIND observatory status: Avionics off, uncontrolled attitude, rotating about the principal axis of inertia. Current orientation supports continuous communication near the edge of the + Z LGA with some solar array input. No telemetry has been received and therefore detailed status is still unknown. Secondary propulsion tank heaters are on in between DSN tracks.

You could simply look up at the welder white sun, or how the UV's have increased 10fold.


You could look at the rest of the planets and see the change.

Why do you think the sun has lost 40% of its heliosphere?

The sun may not be dying but we are about to go for a ride, that I can guarantee.
 Quoting: Anonymous Coward 72711495


The Sun's colour spectrum and temperature is well known. Photographic colour daylight balance is the same now as it was decades ago.

Nothing particularly unusual is happening to the planets despite even more youtube videos claiming all sorts of nonsense.

If UV reaching me had increased 10 fold I think I would have noticed.

Heliosphere pulses along with the solar cycle and longer cycles which we haven't been measuring long enough to fully understand. It's not possible to say whether anything is particularly unusual or not.

Now if the Sun looked like it was building up to an X1000 and massive CME flung at us I would get worried and we know that the Sun can do this - just not very often. But at the moment we're just starting to drop back down from the Kp disturbance peak which appears to trail the sunspot peak based on the limited time we have data for. Youtube videos call this "Our shields are down" ignoring that this is exactly what happened last cycle when there was even more storming post solar peak.

DSS-43 Canberra is now uplinking a data stream to Stereo-B
This should be the first attempt to begin powering up the avionics according to the schedule.

I just hope they have enough time to complete all the steps including getting propulsion back online before the spacecraft drifts out of alignment for power and comms. I guess they've done the calculations and how long they likely have but it hasn't been mentioned yet in any update. They have said that it will be 2022 before conditions are as favourable again as now...

The primary propulsion tank heaters (~30W) were enabled at 1530z on Friday, Aug 26. During the second track, after the IEM was powered, the downlink signal would drop out periodically. From analysis of the Doppler residual data from the FDF, the rotation is more complex, there is an ~14 minute rotation with the previous ~2 minute rotation. This appears to have shifted the spin axis from 10.5 deg to 22 deg. Three packets of critical telemetry were received. From this very limited data, as expected, the observatory is quite cold, with the battery at 30% state of charge and generating power to support ~150W. From the propulsion tank pressures, the tanks appear to be frozen; however, no temperature data were received. The Sun angle averaged ~ 60 degrees. As the main bus voltage was 24v and falling, the transmitter was powered off early. While early in recovery, 2 of 11 battery cells appear not to be functioning. Verified that the increased battery charge rate command to C/4 was received. From engineering team discussions, it was decided to power off the IEM and power on the secondary battery heater to allow the battery to recharge. The secondary propulsion tank heaters were also powered on to continue thawing of the hydrazine.

BEHIND observatory status: Avionics off, uncontrolled attitude, complex rotation about the principal axis of inertia. Current orientation supports nearly continuous communication near the edge of the + Z LGA with some solar array input. Propulsion tanks are frozen. Secondary battery and propulsion tank heaters are on in between DSN tracks.

Today's Canberra track has just started. The Goldstone pass earlier today seems to have been cancelled (at least it didn't appear on the DSN website) possibly because they wanted more battery charge time after first telemetry yesterday indicated battery at only 30% charge. Let's see if they turn the computer (IEM) back on for more telemetry this pass.

I agree, my English AC friend. You state the truth here. I would like to see links to the data that shows the Heliosphere has shrunk by 40% and that UV rays have increased 1000%.

It may seem counter-intuitive, but the sun may cause greater trouble for Earth by INACTIVITY--rather than the rare mega-CME. Major earthquakes, huge volcanic eruptions, increased Galactic Cosmic Rays and mini-Ice-Ages have been attributed to a 'quiet sun'. "Space Junk' can also accumulate and cause problems during low solar activity cycles.

Okay well the brief summary so far is that NASA found they had less power available on Friday than they had hoped for and that they had more complex spin than they thought. To correct the spin they need the propulsion back online but the fuel is frozen. Tank heaters are switched on. If they can't heat the fuel and keep the battery charged prior to attitude correction (to bring solar panels fully online) then they run out of time. Low voltage forced them to switch off the IEM (Integrated Electronics Module - main computer) shortly after they powered it up on Friday.

Last night's track pass I didn't see a downlink signal but the transmitter might have only been on for a short time and I missed it. Hopefully they didn't command the transmitter on then not see a downlink.

Yesterday's Goldstone track which was cancelled seems back on for today as the 70m DSS-14 is preparing for STEREO-B now. I'll be looking for the downlink signal and whether it is carrier or carrier + data. Real Time status [link to eyes.nasa.gov (secure)]

Given enough time I'm confident that if the craft can be rescued then they will do it but so far we haven't been given a clue as to roughly how long they think the current alignment window will last.

One other possible anomaly I've noticed is that NASA produced a simulation of what they expected STEREO-B to have done given the bad data from the Inertial unit. They expected it to have spun up to several revs per minute before a time limit expired cutting thrust. It's actually only spinning at one quarter of their predicted rate from their best guess.

That Telegraph report is from 2008 at about solar minimum. Look at the long term neutron monitor below and you will see that cosmic rays at Earth pulse up and down with the cycle as the heliosphere blocking ability also pulses.

The highest level of incoming cosmic neutrons (implying weaker heliosphere) so far was in 2009. See [link to cosmicrays.oulu.fi (secure)] and note how it follows the solar cycle.

No it's not from 2015. It's also from 2008 but has an incorrect date of 2015. Check the comments on the article and you will see they are from 2008!!

The heliosphere increased again after 2009 but is weakening again now after solar max as expected.

Also see this from the end of the article which also dates it:

"So what could this be attributed to? Physicists simply do not know. Perhaps it might be related to the extended solar minimum in recent months, as Smith appears to suggest. “The sun cycles between periods of great activity and lesser activity,” Smith said. “Right now, we are in a period of minimal activity that has stretched on longer than anyone anticipated.”

Bad news as I feared

[link to stereo-ssc.nascom.nasa.gov]

August 28, 2016

On Saturday, August 27, during the evening recovery track, no downlink signal was received after repeated commanding the transmitter on. Battery recovery commands were sent for the last hour of the support.

On Friday evening, as battery voltage was decreasing from the three telemetry packets received, the transmitter was powered off early. However, the downlink signal was lost 6 minutes earlier than expected. It is speculated that with the complex roll, which resulted from powering on the IEM, the battery voltage may have collapsed at some point.

BEHIND observatory status Unknown state of power, uncontrolled attitude, complex rotation (~14 minute rotation with the previous ~2 minute rotation) about the principal axis of inertia. Current orientation may support communication near the edge of the + Z LGA with some solar array input. Propulsion tanks are frozen.

Thanks.

Speculation only:

A circuit breaker was stuck in the open position and they powered up more than they intended? While watching the Friday night downlink I was astonished at one point to see received power level increase 100 fold. Also the signal strength held constant without the 2 minute roll modulation. At the time I assumed there must be an error in the displayed data (and that mat still be the case) but if guidance control came on unexpectedly the spacecraft may have tried to correct itself and then something went wrong.

I hope it doesn't turn up they switched to monthly tracks too early (ie they could have started the recovery weeks earlier if they'd only tried) and ended up rushing the recovery. Still crossing fingers though.

Canberra is currently uplinking. No downlink seen.

I hope it doesn't turn up they switched to monthly tracks too early (ie they could have started the recovery weeks earlier if they'd only tried) and ended up rushing the recovery. Still crossing fingers though.

Canberra is currently uplinking. No downlink seen.

I was wondering if they fuel being heated (after frozen) could offset its balance?

Re: SOLAR WATCH * Huge X8.2 Flare Sept. 10, 2017! (Updated Daily)
I'm not understanding why they had a "complex roll" after powering on the computer. Supposedly the momentum wheels and and propulsion were off so how could it roll unless they missed something?

Thanks.

Speculation only:

A circuit breaker was stuck in the open position and they powered up more than they intended?

I meant circuit breaker physically closed but open (i.e. on) to current flow in case that wasn't obvious.

Interesting question with a lot of variables. Probably not that significant would be my first guess as they seem to be fingering the IEM power up.

No it's not from 2015. It's also from 2008 but has an incorrect date of 2015. Check the comments on the article and you will see they are from 2008!!

The heliosphere increased again after 2009 but is weakening again now after solar max as expected.

Also see this from the end of the article which also dates it:

"So what could this be attributed to? Physicists simply do not know. Perhaps it might be related to the extended solar minimum in recent months, as Smith appears to suggest. “The sun cycles between periods of great activity and lesser activity,” Smith said. “Right now, we are in a period of minimal activity that has stretched on longer than anyone anticipated.”
 Quoting: Anonymous Coward 72872393


Well let's look at where we are today in the solar cycle, we're not in one. We are in the twighlight zone of solar cycles. And I can assure you the Heliopshere has not improved since 2008 or when these deviations first really started showing up.
