Universe, we have an issue: The payload laptop aboard the Hubble Area Telescope that has formed our understanding of the cosmos for over 30 years has stopped working.

After the June 13 malfunction, Hubble’s payload laptop stopped receiving the “keep-alive” sign that is a “commonplace handshake between the payload and primary spacecraft computer systems to point all is properly,” in response to a NASA news release.
Following the primary laptop’s computerized shift of all science devices to protected mode, management heart personnel at NASA’s Goddard Area Flight Middle in Greenbelt, Maryland, restarted the payload laptop however it quickly halted as soon as once more on June 14.
