‘My power’s really low’: Nasa’s Insight Mars lander prepares to sign off from the Red Planet

Robot says it might be sending its last message from Mars as dust chokes out its power supply

Nasa's InSight lander has delivered what could be its final message from Mars, where it has been on a history-making mission to reveal the secrets of the Red Planet's interior.

In November the space agency warned the lander's time may becoming to an end as dust continued to thicken and choke out the InSight's power.
