Elon Musk says a 'radical change' is coming to SpaceX's monster Mars rocket design

• In a tweet, Musk revealed that "radical change" was coming to the design of the Big Falcon Rocket (BFR), which is meant to go to Mars.
• The tweet appeared to indicate that the second stage of the Falcon 9 will now be used for component tests for the BFR, and that the company is abandoning plans to make the second stage of Falcon 9 reusable. 
• Musk has said that his "aspirational" goal is to launch an unmanned cargo mission to Mars by 2022.

In a tweet, Saturday, SpaceX founder Elon Musk announced that "radical change" was coming to the design of the Big Falcon Rocket (BFR), that is being made in an attempt to go to Mars.

In September, Musk announced that Yusaku Maezawa, a Japanese billionaire and art collector would be the first passenger of the BFR. Along with eight artists, Maezaqa intends to complete a week-long mission called "#dearMoon."

Previously, designs for the BFR included a 180-feet tall spaceship atop of a 230-foot-tall rocket booster that promised to lift up to 150 tons of cargo and ferry as many as 100 passengers to Mars. It's unclear how much of this is set to change under Musk's reported redesign.
