The US space agency's Perseverance rover has wiggled its wheels and undertaken its first Martian drive.
It didn't move far - just 6.5m in total.
But Nasa scientist believe it was a significant moment.
While the rover is still doing a lot of engineering checkouts, the minute 'the rubber' begins to move it should be considered as "explorer" on the surface of Mars.
Security has been tightened at the US Capitol in Washington in response to "a possible plot to breach" the building.
The move was prompted by intelligence that a militia group planned the attack for 4 March - the day conspiracy theorist group QAnon believes Donald Trump will return for a second term.
Capitol Police say they have uncovered intelligence of a "possible plot" by a militia group to breach the U.S. Capitol on March 4, nearly two months after a mob of supporters of then-President Donald Trump stormed the iconic building to try to stop Congress from certifying now-President Joe Biden's victory.
President Joe Biden on Feb. 24 formally revoked a series of presidential orders and memorandum signed by Donald Trump, including one that sought to cut funding from several cities the 45th president deemed "anarchist" havens and another mandating that federal buildings should be designed in a classical aesthetic.
Missed intelligence was to blame for the outmanned Capitol defenders' failure to anticipate the violent mob that invaded the iconic building and halted certification of the presidential election on Jan. 6, the officials who were in charge of security that day said in their first public testimony on the insurrection.
The government meets today, Friday, to approve the bills related to the national budget and the state social insurance budget for 2021. Prime Minister Florin Citu said on Thursday that the government deficit target remains set at 7.16%, specifying that, compared to the published version of the draft, there could be some changes in terms of allocations, with more commitment appropriations.
