Elon Musk has promised to solve an energy crisis in Australia within 100 days, or provide the technology for free.
The Tesla (TSLA) founder was responding to a challenge from billionaire entrepreneur Mike Cannon-Brookes, who wanted to know whether the company was serious in claiming that it could end blackouts in South Australia quickly.
"Tesla will get the system installed and working 100 days from contract signature or it is free. That serious enough for you?," Musk wrote on Twitter.
Beijing (AP) -- China is developing an advanced new spaceship capable of both flying in low-Earth orbit and landing on the moon, according to state media, in another bold step for a space program that equaled the U.S. in number of rocket launches last year.
The newspaper Science and Technology Daily cited spaceship engineer Zhang Bainian as saying the new craft would be recoverable and have room for multiple astronauts. While no other details were given in the Tuesday report, Zhang raised as a comparison the Orion spacecraft being developed by NASA and the European Space Agency. The agency hopes Orion will carry astronauts into space by 2023.
Elon Musk's Space Exploration Technologies (SpaceX) plans to send two private citizens on a trip around the moon late next year as it continues to work with NASA for a crewed mission to the International Space Station. The passengers, who paid a "significant deposit," will undergo health and fitness tests and begin initial training later this year, the company said. SpaceX didn't identify the two citizens or say how much they spent. "It's a pretty big mouthful to take two private citizens to orbit the moon," Marco Caceres, a senior space analyst with Teal Group, an aerospace and defense market researcher, said in an interview. "It's pretty risky; these are private citizens, which is different from an astronaut."
