A Dragon visits the ISS

ELON MUSK'S AMBITION to launch people into orbit around Earth took another step forward on March 3rd. That was when a Crew Dragon space capsule, built by Mr Musk's company, SpaceX, docked successfully with the International Space Station (ISS).

NASA, Roscosmos Reach Consensus on Upcoming Crew Dragon Unmanned Flight to ISS

MOSCOW (Sputnik) – NASA has received the concurrence of Russian space agency Roscosmos on the planned first unmanned test flight of the US Crew Dragon capsule to the International Space Station (ISS), Joel Montalbano, NASA’s deputy ISS Program.
“We agreed with Roscosmos yesterday on a protocol of the approach, actually, through discussions with them, explaining what steps SpaceX has taken in order to ensure the safety.They asked for some additional steps where we would protect the space station, close another hatch or two, have the Soyuz, have the crew ready to go to the Soyuz. We agreed to do that”, Montalbano told a press conference, broadcast by NASA’s YouTube channel, on Thursday.
Last week, the US agency announced its plans to send the capsule, designed by private aerospace contractor SpaceX, UFO Caught on TV Zooming Over Cleveland, and You Won’t Believe NASA’s Response NASA officials then said that their Russian colleagues had concerns related to the US agency’s lack of a backup computer system to prevent Crew Dragon from colliding with the ISS if the vehicle goes dead.
The flight control teams were to finalize the procedures later that day, Montalbano pointed out.Crew Dragon, also known as Dragon 2, is a reusable spacecraft designed as a successor to the Dragon space freighter.Its launch atop the Falcon 9 rocket for the unmanned test mission is scheduled for 2:48 am EST (07:48 GMT) on 2 March. The spacecraft is expected to reach the ISS on 3 March.

China Plans To Build Space Solar Station

Chinese scientists have revealed plans to build and launch in orbit a space solar station that could capture the Sun’s rays 24/7, Chinese media report.
China has already started to build an early experimental space power plant in the city of Chongqing, The Sydney Morning Herald reported, citing an article in China’s Science and Technology Daily.The space solar station, planned to orbit the Earth at 36,000 kilometers (22,370 miles) could provide an inexhaustible source of clean energy for humans, according to Pang Zhihao, a researcher at the China Academy of Space Technology Corporation.Such solar power technology could supply reliable energy 99 percent of the time and have six times the intensity of the solar farms that work on the earth, the scientist says.China will start by launching small solar stations between 2021 and 2025, while a possible next step would be a Megawatt-level station planned to be built in 2030.The energy from the space solar station would be converted into a microwave or laser beam that would be sent to the earth.
However, the project has two major hurdles to overcome in order to become a practical solution. One is the weight of a space solar station, expected to be more than two times the weight of the International Space Station.The other is the safety impact of laser or microwave beams sent to the earth.Related: 2 Reasons Why Big Oil.Isn’t Rushing Into Renewables China is not the only country studying the potential of harnessing the power of the Sun in space.Caltech for example has its Space Solar Power Project, which has researched the use of ultralight, foldable, 2D integrated elements, Caltech has developed a prototype which collects sunlight, converts it to RF electrical power, then wirelessly transmit that power in a steerable beam.According to Caltech’s research, Collecting solar power in space and transmitting the energy wirelessly to Earth through microwaves enables terrestrial power availability unaffected by weather or time of day.
