After an error that occurred in late October pressured it into protected mode, the Hubble House Telescope is now again up and working at full power.
Hubble suffered a difficulty with the communications between its computer systems and devices on October 25, when a number of synchronization messages have been misplaced. To stop any injury to its devices, the telescope robotically went into protected mode by which solely the fundamental important components of the telescope functioned. That meant that it stopped accumulating science information whereas engineers on the bottom discovered what had gone flawed.
All through November, the Hubble workforce analyzed the problem and examined out the issues by turning on an older, unused instrument. This allowed them to carry out a check with out endangering the presently lively devices which Hubble nonetheless wants to make use of.
As that check didn’t throw up any extra errors, the workforce elected to activate every of Hubble’s 4 presently lively devices one after the other. With no extra missed synchronization messages, they turned on the ultimate instrument — the House Telescope Imaging Spectrograph — this week.
“NASA’s Hubble House Telescope workforce recovered the House Telescope Imaging Spectrograph on Monday, December 6, and is now working with all 4 lively devices accumulating science. The workforce has nonetheless not detected any additional synchronization message points since monitoring started November 1,” NASA wrote in an replace.
NASA additionally defined that its Hubble workforce has a plan to forestall comparable points from taking place once more sooner or later, by permitting the devices to proceed working even when just a few synchronization messages are misplaced. To make this alteration, they’ll regularly make tweaks to Hubble’s software program over the following few months, starting within the subsequent weeks.
“The workforce will proceed work on creating and testing adjustments to instrument software program that will enable them to conduct science operations even when they encounter a number of misplaced synchronization messages sooner or later,” the replace mentioned. “The primary of those adjustments is scheduled to be put in on the Cosmic Origins Spectrograph in mid-December. The opposite devices will obtain comparable updates within the coming months.”
This was the second time this yr that Hubble has been in hassle, with a difficulty with its laptop inflicting it to enter protected mode this summer time as nicely.
