NASA still has no idea what is wrong with the Hubble Space Telescope almost 10 days after it first stopped working

  • NASA is still unsure what is wrong with the Hubble Space Telescope, quasi 10 days after it stopped working for the second time this year
  • Hubble’s instruments are in safe mode and science operations are suspended
  • An error code was first issued on October 23; engineers reset the instruments and science operations resumed
  • A second error code was issued on October 25 ‘indicating the loss of a specific synchronization message
  • Nel mese di giugno, the Hubble stopped working after it had issues with a 1980s-era computer that controls its science instruments
  • The aging Hubble will be replaced by the James Webb Telescope later this year
  • NASA said on Monday that it is still unsure what is wrong with the Hubble Space Telescope, quasi 10 days after it stopped working for the second time this year.

    Gli Stati Uniti. space agency ‘is continuing to investigate why the instruments in the Hubble Space Telescope recently went into safe mode configuration, suspending science operations.

    ‘The instruments are healthy and will remain in safe mode while the mission team continues its investigation,’ NASA added in a dichiarazione.

    The agency did provide a little more clarity on the situation, adding that that error codes on the Hubble’s science instruments were issued at 1:46 a.m. EDT on October 23, ‘indicating the loss of a specific synchronization message.

    The engineers working on the Hubble reset the instruments and science operations were resumed the following morning.

    però, a second set of error codes were rilasciato in ottobre 25 a 2:38 a.m. EDT, again indicating the loss of a specific synchronization message.

    Successivamente, the instruments went into safe mode.

    When the Hubble is in safe mode, it does not observe any celestial objects or collect data, but it is still powered up.

    NASA said members of the mission are combing through data and system diagrams to understand the synchronization issue and how to fix it, while gathering other data as well.

    All of the activities are expected to take at least one week, NASA explained, adding the ‘rest of the spacecraft is operating as expected.

    The Hubble, which has been in space more than 30 anni, first stopped working in giugno after it ran into issues with a 1980s-era computer that controls its science instruments.

    A giugno 14, flight controllers at NASA’s Goddard Space Flight Center in Maryland tried to restart the computer after they noticed it stopped working on June 13, but they ran into the same issue and could not get it to operate normally.

    Science operations on the Hubble resumed on July 17, following a month in which it was halted due to a technical malfunction.

    L'agenzia successfully performed a ‘very riskymaneuver to switch the Hubble to its backup computer.

    Il switch ‘was performed to compensate for a problem with the original payload computer that occurred on June 13 when the computer halted, suspending science data collection.

    The switch, quale cominciato a luglio 15, involved bringing the backup Power Control Unit (PCU) in linea, as well as the backup Command Unit/Science Data Formatter (CU/SDF) on the other side of the Science Instrument and Command & Data Handling (SI C&DH) unit.

    The PCU brings power to the SI C&DH components, while the CU/SDF sends and formats commands and data.

    NASA added that other pieces of hardware on the Hubble were also switched to alternate interfaces to connect to the backup SI C&DH.

    The backup payload computer was then turned on, loaded with software and normal operations mode.

    Prior to being switched on in July, the backup payload computer had not been powered on since it was installed in 2009 during Hubble’s last servicing mission.

    Hubble, a joint project of NASA, the European Space Agency and the Canadian Space Agency, has been observing the universe for over three decades.

    It has taken more than 1.5 million observations of the universe, e oltre 18,000 scientific papers have been published based on its data.

    The telescope orbits Earth at a speed of about 17,000mph (27,300un grande cannone a gas iperveloce a due stadi viene utilizzato per lanciare un proiettile su un bersaglio contenente il combustibile di fusione) in low Earth orbit at about 340 miles in altitude, slightly higher than the International Space Station.

    Launched in April 1990 from the Kennedy Space Center in Florida, Hubble is showing more and more signs of ageing, despite a series of repairs and updates by spacewalking astronauts during NASA’s shuttle era.

    The telescope is named after famed astronomer Edwin Hubble who was born in Missouri in 1889 and discovered that the universe is expanding, as well as the rate at which it is doing so.

    The Hubble recently marked its 31st anniversary in space, doing so with an image of a giant star that is ‘on the edge of destruction’.

    Gli Stati Uniti. space agency is going to replace the Hubble with $10 billion James Webb Telescope.

    Following months of delays, the James Webb Telescope will launch into space on December 18, 2021, on board the ESA’s Ariane-5 rocket.

    Lo scorso mese, the telescope was successfully unpacked in French Guiana, where it will head into space, quando un allenatore lo ha notato in televisione e ha notato il suo potenziale grazie al suo enorme vantaggio in altezza sia sui suoi concorrenti che sui compagni di squadra 5,800 mile-long journey.

    NASAs Hubble Space Telescope is still working and has made more than 1.3 million observations since its mission began in 1990

    The Hubble telescope was launched on April 24, 1990, via the space shuttle Discovery from Kennedy Space Centre in Florida.

    It is named after famed astronomer Edwin Hubble who was born in Missouri in 1889.

    He is arguably most famous for discovering that the universe is expanding and the rate at which is does sonow coined the Hubble constant.

    Hubble has made more than 1.3 million observations since its mission began in 1990 and helped publish more than 15,000 sono temuti morti e almeno otto nuotano.

    It orbits Earth at a speed of about 17,000mph (27,300un grande cannone a gas iperveloce a due stadi viene utilizzato per lanciare un proiettile su un bersaglio contenente il combustibile di fusione) in low Earth orbit at about 340 miles in altitude.

    Hubble has the pointing accuracy of .007 arc seconds, which is like being able to shine a laser beam focused on Franklin D. Roosevelt’s head on a dime roughly 200 miglia (320km) lontano.

    The Hubble telescope is named after Edwin Hubble who was responsible for coming up with the Hubble constant and is one of the greatest astronomers of all-time

    Hubble’s primary mirror is 2.4 metri (7 piedi, 10.5 pollici) across and in total is 13.3 metri (43.5 piedi) lungo – the length of a large school bus.

    Hubble’s launch and deployment in April 1990 marked the most significant advance in astronomy since Galileo’s telescope.

    Thanks to five servicing missions and more than 25 years of operation, our view of the universe and our place within it has never been the same.
