Hubble did not respond for more than a week

Since last week, Hubble’s on-board computer controller has stopped working. NASA is trying to restart it, but for now without success. Should we say goodbye to Hubble? While waiting for his news, let us re-read the pages of his history a little.

In DeMaeus, The Myth of Atlantis Exposed Work and Philosopher and Mathematician Alfred North Whitehead Considered one of the most important works of birth Cosmology If the Western scientist Plato had a vision, it would be ” So by exploring the skyIntelligence Eternity, we have learned to guide those in our minds, despite the disorder of their movements, which are similar to these other organized circles, and what is instructed by this scene to give our eyes the most regular direction is that our nature, like the divine circles, controls within us those who deviate from their path. .

Mankind’s march towards knowledge and reason fully justifies the visionary intuition thus expressed. More than two millennia of Plato’s dialogues have been written, Henry Boycore Echoed him in his work The value of science. In his sixth chapter devoted to the field of astronomy, he writes that this master of astronomy, who expects confusing theory, wants to show his reader, above all, ” How it helped the work of other sciences in astronomy, they are used very directly because this is what made us a soul that understands nature .

Hubble made important discoveries and confirmed many hypotheses. The discovery of dark energy was relatively unexpected, but telescopes confirmed the existence of miraculous black holes in galaxies. It also made it possible to study the atmospheres of exoplanets. Here is a video with testimonials from some astronomers who used it for its 25th anniversary.

Two on-board computers and four unwanted memory modules for Hubble

The Hubble Space Telescope undoubtedly contributed to Plato’s plan for Nuspier almost 2,500 years ago. We hope it is not completed by any means NASA ‘S crash problem has not yet been successfully resolvedComputer Hubble Edge. Although not dating its twin gods since the Paleo-Computing age, Touring Ed von Newman, Le NASA Standard Space Shuttle System-1 (NSSC-1) still dates back to the 1980s, and is seen as a result of aging in space. Now the Spacecraft It is no longer allowed to be directly adjusted or changed.

The discoveries he made all point to the fact that Hubble tools are still in perfect order. But maybe we should decide to grieve this Eye Humanity in orbit. Without scrolling through her life before she died, it was an opportunity to remember some important dates and events that marked her with videos for her 30s.e And 25e Birthday.

Hopefully anyway, if we believe the NASA message, the problem we are facing is related to the system’s memory modules. There are 4 of them, they are unnecessary and they are only used Backups The system usually uses only one module. But above all, in this press release, let NASA know that there were actually two NSSC-1 type computers, if I am not mistaken, it is precisely the backup system. Unnecessary.

  • 1946: Astronomer Lyman Spitzer Writes a report on the benefits of an extraterrestrial laboratory.
  • 1977: US Congress approves funding for a large space telescope.
  • 1990: Spacecraft Discovery (SDS-31) launched on April 24. The next day, Hubble was used in space, but the first images were taken on June 25, 1990 Glass Hubble President is a victim Spherical variation. All images are blurry. This variation will be resolved thanks to a coaster tool that was installed during the 1993 SDS-61 mission.
  • 1994: Hubble provides detailed observations of the comet Shoemaker-Levy9 Collides with the planet Thursday. In addition, by observing the galaxy M87, Provides solid evidence for the existence of Hubble Supermassive black holes In the centers Constellations.
  • 1996: The first Hubble seen in late 1995 allows deep field Astronomers Read constellationsThe universe Primitive. In the same year, the Hubble host solves galaxies Quasars.
  • 2001: Hubble manages to measure the presence of certain components in the atmosphere of Exoplanet HD 209458b.

Hubble stopped working

Article Celine Telecharch Released on 06/19/2021

Launched in 1990, the space telescope Hubble Accumulates damage. NASA Announced June 16th A complete shutdown of the on-board system was noted on Sunday, June 13, after 4 p.m. The on-board system that controls all the instruments of the telescope has gone into idle mode, apparently for a reason Memory card Defect. Control Center staff Goddard Space Aviation Center NASA tried to restart the system on Monday, but soon encountered the same problem.

This system is not new: it was built in the 1980s, and the memory card was replaced during the last work Maintenance This failure follows A series of other issues Occurred on various instruments in recent years, and explains the aging status of this telescope, which will no longer be up to date. Unfortunately, the release of the James Webb Telescope, which was supposed to replace it in 2018, Never stop being late And is almost ten years behind its initial schedule. We hope this will be reliable because, at a distance of 1.5 million km from Earth (as opposed to 600 km to Hubble), it will be inaccessible for maintenance operations.

Meanwhile, the team Goddard Space Aviation Center Attempts to restart the system in safe mode by switching to a backup memory card. If these efforts are successful, Hubble Its scientific instruments will be tested for a day before being restarted. Otherwise, the observations of the universe would indicate a large vacuum.
