President jokes while signing space agency funding bill

President Donald Trump joked that Nasa could send the US Congress to Mars as he signed a bill that guaranteed funding for the space agency for the next financial year.

The bill includes money to go towards a manned mission to Mars, Nasa's next big goal.

Despite this, the Nasa budget fell slightly, from $19.5bn ( £15.6bn) in 2017 to $19.1bn in 2018.
