The vessel carrying the rover Perseverance of Nasa to Mars is experiencing technical difficulties and is currently operating using only its essential functions, said Nasa several hours after its launch, while pretending to be reassuring about the future of the mission.

"the data indicate that the vessel is entered in a state known as safe mode, probably because a part of the ship was a little colder than expected "when he" stood in the shadow of the Earth, " said the us space agency.
