More trouble for Hubble this week as the space observatory’s scientific instruments package entered safe mode again. The problems started back on October 25, when the Scientific Instrument Command and Data Handling Unit, or SI C&DH, detect a lack of synchronization messages from the scientific instruments — basically, the cameras and spectrometers that sit at the focus of the telescope. The issue appears to be different from the “payload computer glitch” that was so widely reported back in the summer, but does seem to involve hardware on the SI C&DH. Mission controller took an interesting approach to diagnosing the problem: the dusted off the NICMOS, or Near Infrared Camera and Multi-Object Spectrometer, an instrument that hasn’t been used since 1998. Putting NICMOS back into the loop allowed them to test for loss of synchronization messages without risking the other active instruments. In true hacker fashion, it looks like the fix will be to change the software to deal with the loss of sync messages. We’ll keep you posted.
What happened to the good old days, when truck hijackings were for things like cigarettes and booze? Now it’s graphics cards, at least according to a forum post that announced the theft of a shipment of EVGA GeForce RTX 30-series graphics cards from a delivery truck. The truck was moving the cards from San Francisco to the company’s southern California distribution center. No word as to the modus operandi of the thieves, so it’s not clear if the whole truck was stolen or if the cards “fell off the back.” Either way, EVGA took pains t ..
