NASAs Deep Space Network, or DSN, established a lock on the STEREO-B (spacecrafts) downlink carrier at 6:27 p.m. EDT, NASA said in a statement. The downlink signal was monitored by the Mission Operations team over several hours to characterize the attitude of the spacecraft and then transmitter high voltage was powered down to save battery power.

Launched in 2006, the STEREO mission featured two spacecraft -- STEREO-A and STEREO-B -- designed to monitor solar activity from different locations, one ahead in its orbit and one behind, allowing scientists to see the entire star, not just the side facing Earth. The spacecraft were built and are managed by the Johns Hopkins University Applied Physics Laboratory in Laurel, Md.

Both spacecraft featured a command loss timer designed to force the flight computer to reboot if it didnt hear from Earth over a three-day period. On the far side of the sun, the command loss timer would trigger repeated computer resets during the three months the spacecraft were out of contact with Earth.
To make sure the system was working properly, flight controllers tested both spacecraft by withholding commands and forcing the command loss time to trigger a reboot. The STEREO-A spacecraft responded normally. But STEREO-B had major problems.
Based on fragmentary data received before contact was lost, engineers concluded the timer triggered a restart as expected, but STEREO-Bs inertial measurement unit and star trackers, which tell the flight computer how the spacecraft is oriented and moving through space, suffered malfunctions.

You and about ten million other boys, including me.
Well, she grew up...
Playing reruns of the lone...rager...
Lone rager? I didn’t know Hillary ever had a tv show.
I always thought Penny was cuter than Judy.
I recently saw some pictures of them now and Penny has put on a bit of weight and is no longer really pretty. Actually she probably looks about like all of us look at her age.
The blonde surprised me. She still looks remarkably good.
“Can you hear me, Major Tom?”
Angela Cartwright bump
Lol me too, peeeeennnneeey
Regular reruns of F-Troop would mess with those Martians’ minds.
CA....
I saw her and Marta Kristen at an autograph signing back in the late 90s. Angela had grown more out than up at that point. Marta was pretty much the same figure wise though.
You are The Kirk.
Uh, yup ...
That, is genius.
“SEND MORE ALUMINUM FOIL!!”
Poor Dr Smith kicked out of the photo opp. “Oh the pain, the pain”
It sent the message “have you dumped that silly Muslim outreach and got a real space program again yet?”
Not heard of in 2 years? This means aliens have messed with the spacecraft. Beware!
