In the history of area expedition, a handful of missions have actually set brand-new records for durability and longevity. On Mars, the undeniable champion is the Opportunity rover, which was slated to run for 90 days but stayed in operation for 15 years instead! In orbit around Mars, that honor goes to the 2001 Mars Odyssey, which is still functional 20 years after it arrived around the Red Planet.
In deep area, the title for the longest-running mission goes to the Voyager 1 probe, which has actually spent the past 44 years checking out the Solar System and what lies beyond. However in Earth orbit, the longevity reward goes to the Hubble Space Telescope (HST), which is once again fully functional after experiencing technical issues. With this newest remediation of operations, Hubble is well on its way to completing 32 years of service.
The concern started at 01:46 A.M. EDT (10:46 P.M. PDT) on October 23rd, when NASA reported that the venerated area telescope was sending mistake codes, which show the loss of a particular synchronization message. This message provides timing information that Hubbles instruments use to react to information requests and commands properly. The same error codes were released 2 days later, suggesting multiple losses of synchronization messages and setting off Hubble to get in safe mode.
In Earth orbit, the durability reward goes to the Hubble Space Telescope (HST), which is once again completely operational after experiencing technical concerns. With this newest repair of operations, Hubble is well on its method to finishing 32 years of service.
The Hubble Space Telescope is released on April 25, 1990 from the space shuttle bus Discovery. After a lengthy examination and multiple efforts to restart Hubbles backup systems, the telescope was brought back to complete operational status by July 17th. On October 26th, after a considerable effort on behalf of the operations group, NASA announced that the age-old Hubble had actually been brought back to working order.

Throughout November, NASAs Hubble group attempted to restart its primary computer system and backup systems. On November 8th, they announced that they had actually retained partial control by bringing the telescopes Advanced Camera for Surveys (ACS) back online. They followed by bring back the Cosmic Origins Spectrograph (COS) and the Wide Field Camera 3 (WFC-3), Hubbles a lot of heavily-used instrument.
On Monday, December 6th, the team announced that all four active instruments were back online after power was brought back to the Space Telescope Imaging Spectrograph (STIS). While the telescope is totally functional once again, this latest glitch and need for repair become part of a repeating pattern. Last June, an unspecified concern caused Hubbles NSSC-1 payload computer system to quit working, triggering it to go into safe mode.
As part of the telescopes Science Instrument Command and Data Handling (SI C&DH) module, this computer controls and collaborates the telescopes scientific instruments. After a prolonged investigation and numerous attempts to restart Hubbles backup systems, the telescope was brought back to complete operational status by July 17th. Back in October 2018, one of Hubbles response wheels failed t to go into safe mode. On October 26th, after a significant effort on behalf of the operations group, NASA revealed that the venerable Hubble had actually been brought back to working order.

Given Hubbles long history of service and the truth that it runs on systems established in the late 80s-early 90s, these two occurrences have actually caused their reasonable share of uneasiness. When a 31-year old objective experiences three significant problems that trigger it to enter safe mode– the most recent of which happened in the last 6 months– one may get the impression it was on its last legs.
And yet, Hubbles heat is as soon as back online after experiencing another scare. According to the latest updates from NASAs Goddard Spaceflight Center, the group will continue developing and testing changes theyve made to the instrument software application. If it experiences several lost synchronization messages in the future, these changes (it is hoped) will allow Hubble to continue running science operations.
The very first of these modifications is set up to be set up on the COS in mid-December, while the other instruments will get comparable updates in the coming months. In its 31 years of operation, Hubble has actually been responsible for a few of the most profound astronomical discoveries. These include offering brand-new measurements on the growth rate of deep space, which revealed that its been accelerating for billions of years (leading to the theory of Dark Energy).

Its deep cosmological studies have actually also resulted in newer, more precise age estimates for the Universe, taught us a good deal about the supermassive black holes (SMBHs) that live at the center of a lot of galaxies. It has actually also been important to the research study of extrasolar worlds, typically by working in tandem with exoplanet-hunting telescopes like Kepler. It has actually been used thoroughly to study the planets, comets, asteroids, and other things in the Solar System.
With the launch of the James Webb Space Telescope (JWST) later on this month, NASA anticipates the 2 observatories will interact throughout the remainder of this years, expanding our knowledge of the universes even further. In fact, some quote that Hubble could be around until the 2030s and 2040s, where it might assist next-generation telescopes like NASAs Nancy Grace Roman Space Telescope (RST), the ESAs Euclid and PLATO spacecraft.
For the 2nd time in the previous year, Hubble has actually revealed us that its not done!
