Nasa's latest space mission has been delayed again.
A pair of spacecraft intended to orbit the moon and measure its gravity will not lift off until Saturday.
Nasa said it needs time to analyse data for the rocket’s propulsion system. Concerns arose following a failed launch attempt on Thursday.
High wind halted the countdown then, and Nasa initially changed the launch date to Friday. But it then delayed it further until Saturday morning local time.
The near-identical twin satellites are named Grail-A and Grail-B. Grail stands for Gravity Recovery and Interior Laboratory.
None of the world’s previous 109 moon missions has been dedicated to lunar gravity like Grail.
This mission will cost 496 million US dollars (£311 million).
