Nasa has finally found the fault with the Hubble Space Telescope

Nasa has identified the possible cause of the issue that stopped the Hubble Space Telescope from working.

The $4.7 billion telescope halted on 13 June, with a degrading memory module appearing to be the fault. The main computer stopped receiving the “keep-alive” signal, which is a standard ‘handshake’ (a way of establishing a connection) between the payload and the spacecraft’s main computers.

The main computer automatically put all instruments on the space telescope in safe mode. Nasa restarted the payload computer the following day in an attempt to resume normal operation, but the problem has persisted.
