Fix pinpointed for Hubble main camera
Engineers have identified the issue that put the main camera of the Hubble Space Telescope into safe mode last week, and expect to have the camera back in operation in two or three days.
Hubble’s Wide Field Camera 3 (WFC3) took itself offline last week as a safety precaution, after onboard software noticed anomalous voltage readings within the instrument. But Hubble team members have now determined that voltage levels actually remained within the normal range, ascribing the glitch to a telemetry issue rather than a power-supply problem.
The mission team reset the relevant telemetry circuits, gathered some more engineering data and then brought the WFC3 back to an operational state. “All values were normal. Additional calibration and tests will be run over the next 48 to 72 hours to ensure that the instrument is operating properly,” NASA officials wrote in a Hubble update Tuesday (Jan. 15).
None of this changes the reality that it is almost a decade since the last shuttle repair mission, and Hubble is facing a long slow decline leading to its eventual loss, with no replacement planned by anyone.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
