Long dead Zombie Satellite wakes up 13 years later


In 2005, a NASA spacecraft named “IMAGE” mysteriously went silent, abruptly ending a successful mission to study Earth’s magnetosphere. Thirteen years later, it’s back. On Jan. 20, 2018, an amateur astronomer in Canada picked up radio transmissions from IMAGE, alive after all. The satellite may have been chattering away at Earth for years unheard and unnoticed. Now NASA is working to regain contact and possibly revive a key asset for space weather research and nowcasting

Amateur astronomer Scott Tilley has a hobby: He hunts spy satellites. Using an S-band radio antenna in Roberts Creek, British Columbia, he regularly scans the skies for radio signals from classified objects orbiting Earth. Since he started 5 years ago, Tilley has bagged dozens of secret or unlisted satellites. “It’s a lot of fun,” he confesses.

Earlier this month, Tilley was hunting for Zuma–a secretive United States government satellite lost in a launch mishap on Jan. 8th–when a J-shaped curve appeared on his computer screen. “It was the signature of a lost satellite,” he says, “but it was not Zuma.”

In a stroke of good luck that has dizzied space scientists, Tilley found IMAGE, a NASA spacecraft that “died” more than 10 years ago.

An artist’s concept of the IMAGE satellite flying over Earth’s north pole.

Short for “Imager for Magnetopause-to-Aurora Global Exploration,” IMAGE was launched in 2000 on a flagship mission to monitor space weather. Mapping the ebb and flow of plasma around Earth, IMAGE was able to watch our planet’s magnetosphere respond almost like a living organism to blasts of solar activity, while its ultraviolet cameras took gorgeous pictures of Earth’s global auroras.

“It had capabilities that no other spacecraft could match–before or since,” says. Patricia Reiff, a member of the original IMAGE science team at Rice University.

IMAGE was in the 5th year of its extended mission on Dec. 18, 2005, when the spacecraft suddenly went silent. No one knows why, although suspicions have focused on a power controller for the spacecraft’s transponder, which might have temporarily failed.

The one hope was a reboot: When IMAGE’s solar-powered batteries drained to zero during a eclipse by the Earth, onboard systems could restart and begin transmitting again. “If revival occurs, the mission should be able to continue as before with no limitations,” noted NASA’s IMAGE Failure Review Board in their 2006 report.

A deep eclipse in 2007, however, failed to produce the desired result. “After that, we stopped listening,” says Reiff.

That is, until Scott Tilley started looking for Zuma. “When I saw the radio signature, I ran a program called STRF to identify it,” he says. Developed by Cees Bassa, a professional astronomer at the Netherlands Institute for Radio Astronomy, STRF treats Earth-orbiting satellites much like binary pulsars–deducing their orbital elements from the Doppler shifts of their radio signals. “The program immediately matched the orbit of the satellite I saw to IMAGE. It was that easy,” says Tilley.

Sometime between 2007 and 2018–no one knows when–IMAGE woke up and started talking. Now, NASA has to find a way to answer.

“The good news is, NASA is working on a recovery plan,” says Reiff. “UC Berkeley still has a ground station that was used for realtime tracking and control. They are scrambling to find the old software and see it they can get the bird to respond. Apparently there are data side lobes on the transmission, so that is a good sign.”

Researchers would love to have IMAGE back. The spacecraft has a unique Big Picture view of Earth’s magnetosphere and “its global-scale auroral imager would be fantastic for nowcasting space weather,” says Reiff. “Fingers crossed!!”

This is a developing story. Stay tuned for updates.

Most likely a SW bug that locked it up and over the years, the batteries weakened and/or the solar cells were not properly aligned to the Sun and eventually the required reboot occurred during a period of relative darkness.
If the GISS ModelE is representative of SW written by NASA, bugs are inevitable.

Any moderately complicated software will have bugs. It’s a matter of planning for something that you can’t predict. It’s complicated.
I wouldn’t tar all of NASA with the same brush. Given the cost of putting a satellite into orbit, the industry is very conservative and has a rather good record. In fact, the reliability of satellite communication systems is quite a bit better than that for terrestrial systems. link

I’m reasonably certain the story is true as presented, but I’ve conceived of a highly unlikely alternate explanation.
It’s a switcheroo. The secretive “missing” Zuma spy satellite was programmed to spoof the zombie satellite IMAGE and launched in a matching orbit, so if it was ever discovered, it would be misidentified. If enough time had passed, no one would ever suspect a connection between the two satellites.
Sure, it’s an insane and paranoid idea, but it’s fun to imagine our secret agencies having such complicated schemes. And then some hobbyist astronomer accidentally uncovering the plot early.

On one of my LEO spacecraft, the primary nadir transponder died. Luckily, the zenith transponder was cross strapped into the receiver. NASA spent two years broadcasting out the zenith antenna and using a huge DSN antenna to pick up the tiny signal scattered from the solar arrays. They could reconfigure the system, but were scared the reconfiguration would fail. Finally they agreed to throw the crosslink switch and connect the zenith transponder to the nadir antenna. Problem fixed.
On another program, our primary processor failed after one year. We tried several times to diagnose the problem without success. After eight more years running on the backup, a single event upset sent us back to the prime processor which came up working perfectly. Go figure.

It is common risk management. There is always a chance a mechanical waveguide switch can get stuck in-between detents. If it is then stuck. you’re hosed. Just engineering caution when their is no-way to send a human to the machine to give in a whack.
Same thing on the Hubble Telescope with the Primary Mirror door/cover. If they close it for some reason (like for a service mission as the maneuvering shuttle approached, then there is always a chance, even if small that it will not re-open fully. When the last STS service mission finished with Hubble repairs, the shuttle stayed nearby, while ground controllers re-opened the door, ready to return in case it got stuck short of full-open.

Reply to  The Reverend Badger
January 26, 2018 6:04 pm

They had a situation where they could use the satellite via the DSN array. Expensive, probably tough to schedule, but it worked. Switching to the nadir antenna could work, or perhaps there was a failure in it that would kill the the only other transponder.
A bird in the hand is (sometimes) worth two in the bush.
There was no way to tell beforehand what the outcome would be. I imagine the first rule of dealing with failing satellites is “Don’t break what we have.” The second rule is probably from IBM – “Think.”

As for Zuma and trying to find a LO – Stealth platform:
The biggest limitation now with spay satellites is they are big and easily tracked by adversaries to know when to hide their activities from a satellite pass. Nork Korea and Iran certainly are certainly getting satellite passage data from China and/or Russia to help hide their missile and nuclear development activites. They know when certain satellites will be overhead. How do you overcome that? Stealth satellites that can manuever every now and then, and use stealthy comms for downlinks.
Furthermore, one can make a LEO satellite with extremely low visible, IR, and radar signatures, but there is of course no way to mask the launch of a large satellite from a a national launch site. Solution: declare the satellite “lost at launch”, then quickly maneuver it to new orbital parameters just after the last booster burns out to foil tracking by Russians, China, and amateurs.
And if you are going to build a multi-billion dollar stealth spy satellite and put it in orbit, is certain that its command radio links and datalinks are stealthy too. Possibly cross-fed using laser-links and/or SHF/mmW frequencies and spread spectrums modulations not readily observable from Earth to other in-orbit satellites then downlinked to Earth using laser-links or frequencies and spectrums not readily observable from Earth.
None of what I have written is certainly new ideas to the Russians or Chinese. We have stealth submarines, stealth destroyers, stealth helicopters, stealth bombers, stealth fighters, stealth drones, so the extension of LO-stealth to space and spy satellites has of course long been expected by every analyst observation for a dozen years..

The problem, of course, is that “stealth” in space isn’t a thing, as anyone w/a passing familiarity w/spaceflight knows. ^_^
Radar can track objects measuring cms or less in length many hundreds of km up, IR can detect heat signatures fractions of a degree above the background of space for thousands of km, and any broadcast from such a satellite is by definition “unstealthy” because it has to be heard on the ground to be of any use in the first place… none of which even addresses the fact that a satellite in sunlight is as unstealthy as it gets thanks to the reflected/reradiated light & heat.
Orbital mechanics is especially problematic, because even w/out prior knowledge of a launch one can use the initial launch track combined w/knowledge of the launch vehicle to pin down not only the precise location of any spacecraft deployed through its first several orbits, but also how much it masses… which in turn lets you guess-timate just how many & of what magnitude of orbital changes said bird is capable. That & the sheer amount of energy needed to change orbits appreciably in & around Earth’s gravity well SEVERELY limits just how much of a surprise any follow-on orbit can be, to say nothing of the fact that any course change = an exhaust plume of some form or other = really not stealthy, especially in IR.
This core reason — that “stealth” is just not much of a thing in space — is why amateurs are routinely able to not only find “classified” satellites (even the ones able to change orbits), but also to guess at the missions & capabilities of said birds as well. It’s exactly why this guy in particular thought he had any chance at all of seeing Zuma in the first place, and is precisely why all the “mystery” around Zuma’s fate is only a matter of theater for the uneducated public: anyone w/a “need to know” regarding Zuma already does!
(Sorry to blow it for fans of The Expanse, e.g., but while that stealth tech is fun to imagine & makes for a nifty plot device, it’s really just not plausible in any way.)

Reply to  RHS
January 26, 2018 6:29 pm

Rather, the satellite orbit needs to be high enough to stay well above the lingering drag of the earth’s atmosphere, but would it not have to be below the earth’s geosynchronous orbit if it is to survey the planet surface? If geosyn’ed, it could only look at 25% some-odd of the surface. That survey (out to the edges of the surface would be blurred and indistinct) would be thorough, but limited in area.

Vanguard 1 was launched in 1958, and it’s still up there. Lowest point in orbit is 408 miles, high point is around 2400 miles, so you don’t have to be geosynchronous (around 23,000) to stay aloft. Wikipedia says the magnetopause is around 40,000 miles, tho, so IMAGE is probably up a ways.

As for Zuma and trying to find a LO – Stealth platform:–”
Anyone interested in the history of “stealth” technology and its effect on international events and relations during the cold war and beyond should read “Skunk Works” by Ben R. Rich. He was the operations head of the highly secret Lockheed unit for almost two decades that developed our “stealth” fighter and had previously developed the U-2 and Blackbird spy planes.
He wrote this shortly before he passed away with co-author Leo Janos (co-author of “Yeager”) and reveals information that has been previously declassified. He discusses in depth the advantage of “spy” planes over satellites in terms of the enemy anticipating over flights, with the obvious disadvantage of having a human pilot that could be shot down, i.e. Gary Powers.
After reading this, it doesn’t take a lot of imagination to figure this reality is still the case. Anyone who wants a realistic view of the world of nuclear weapons and how nations defend themselves against them should read this book. It’s also a good read. I couldn’t put it down!

I also recommend “Blackbird” by Ben Rich. He was the number 2 for years under Kelly, the main brain behind nearly every innovation in aviation from the F104 to the SR71 and first stealth fighter.
I was so impressed when I finished I immediately read it again from cover to cover. It has a great way to learn how to do cutting edge R&D on a budget – something I am often forced to do by circumstances.
Ben said that we will not use chemistry to go to Mars, we will use a different type of drive system and he had already seen it working. He said many other things of interest. Ben, who was an engineer, invented the extensible conical entrance to the SR71 engines that intake 100,000 cu ft of air per second, creating a sonic boom inside the entrance of the engine, whatever the supersonic speed, that provides about 65% of the thrust. Sheer genius.

Reply to  Martin A
January 27, 2018 2:03 pm

A radio carrier is typically a pure tone, a “bandwidth” of zero. For it to carry some information, it needs to use more than just the carrier frequency. For AM radio, which is easy to generate and decode, the signal winds up using the carrier +/- the highest frequency of the sound being transmitted. In the US that’s limited to a bandwidth under 5 kHz.
In this case, people looking at the radio signal saw the carrier (so the transmitter is on) and other frequencies (hopefully real data).

Whoa, it came back through the worm hole after all these years. Or it was due to global warming.

Seems clear to me. Alien intervention is more than obvious. Once decoded the new message will be “All your satellites are belong to us.” Prolly the same guys who built the pyramids.

Maybe it’s actually ‘Sentinel’ luring us to pick it up!

You would think that for a mission that exceeds well over 100 million, that due diligence would require at the very least, NASA purchase a 200 dollar laptop, freeware software, a cheap SDR unit and a coat hanger for antennae, to monitor for possible future IMAGE transmissions, especially since the investigation and final report of its failure stated that the satellite could come back to life at some future date.

Cheap off-the-shelf solution – not the NASA way.

One thing I don’t quite get.
Would it be too much weight to add a monitoring chipset with CMOS memory which could externally reboot the system when communications have failed? Maybe I don’t have enough grasp of the technology, but that seems to be better than waiting for battery depletion for a reboot.

Flight of the Navigator: “A 12-year-old boy goes missing in 1978, only to reappear once more in 1986. In the eight years that have passed, he hasn’t aged. It is no coincidence that at the time he “comes back”, a flying saucer is found, entangled in power lines.” (from IMDB)

Amateur science is alive and well! Some of the best scientists in history were amateurs (hobbyists): Newton, Lavoisier, Benjamin Franklin, Joule, Heaviside, Tsiolkovsky, Wright Bros. Einstein
Here’s top 10 discoveries made by amateur astronomers
My favorite amateur is the 13-year old boy from Quebec who discovered the alignments of ancient Mayan cities to the stars in the constellation by just surfing the internet in his bedroom. The experts are skeptical but verdict is still out there
