If needed, the spacecraft can be re-configured to run with just one gyro, with the other staying gyro placed in reserve.The spacecraft had six brand-new gyros set up during the 5th and final area shuttle servicing mission in 2009. To date, three of those gyros remain functional, consisting of the gyro that simply experienced changes. Hubble utilizes three gyros to make the most of effectiveness, however might continue to make science observations with only one gyro if required.NASA expects Hubble will continue making groundbreaking discoveries, working with other observatories, such as the agencys James Webb Space Telescope, throughout this decade and potentially into the next.Launched in 1990, Hubble has been observing the universe for more than three years and just recently celebrated its 34th anniversary.
