While searching for spy satellites in orbit, amateur astronomer discovered signals from a NASA project called IMAGE that was thought to have been lost years ago.<\/b>
\nScott Tilley is an amateur visual and radio astronomer whose hobby is tracking satellites \u2014 specifically, classified spy satellites. As detailed at his blog Riddles in the Sky, he recently stumbled across something unusual: a NASA satellite that has been lost in space since 2005, happily chattering away to anyone who would listen.
Luckily, Tilley was.
Tilley was on a hunt for Zuma, the secret Air Force spy satellite that was launched aboard a SpaceX Falcon 9 rocket on January 7, but failed to achieve orbit. No one knew what Zuma was or what its mission was, but initial reports suggest that the Falcon 9 had no part in the mission failure, and it may have been due to the uncoupling procedure designed by Northrop Grumman, which built the satellite.
In any case, Zuma supposedly met with a fiery death on reentry. Or did it?
While searching for any evidence of the classified satellite in orbit, Tilley ran across some unusual transmissions. Subsequent observations indicated that they were likely coming from a 17-year-old NASA satellite called IMAGE (Imager for Magnetopause-to-Aurora Global Exploration), which was launched on a Delta-II rocket in 2000 to map the Earth\u2019s magnetosphere. IMAGE used a variety of sensors, including neutral atom, ultraviolet, and radio imaging to observe plasma in the upper magnetosphere.
After years of successful operation, IMAGE ceased responding in 2005, possibly due to a power failure in the transponder controller. However, there remained the possibility that IMAGE could reboot itself when it passed through the Earth\u2019s shadow.
\u201cPeriodically the spacecraft will enter an eclipse and NASA surmised that this may trigger it to restart and apply power back to the communications system. That appears to have happened!\u201d Tilley wrote. \u201cAs you will note from the plots below the Sun angles are presently good for IMAGE and it may just stay operational for some time to come.\u201d
Word of the discovery quickly reached scientists who had worked on the mission, according to Science. \u201cThe odds are extremely good that it\u2019s alive,\u201d said Patricia Reiff, a space plasma physicist. \u201cThe team is collectively holding their breath waiting for some real information exchange between IMAGE and the ground.\u201d
America Space reached out to the space agency for comment, and they were cautiously optimistic. \u201cWe\u2019re still not sure it really is IMAGE, but we are working to identify people knowledgeable about the mission after all this time and working on getting all the appropriate scripts and software in-place just in case it is IMAGE,\u201d said Jeff Hayes of NASA.
If the spacecraft is indeed operational, it could resume its mission by monitoring Earth\u2019s northern auroral zone. \u201cAt the very least it made for an interesting Saturday afternoon in the radio room,\u201d said Tilley.<\/p>\n
