Climate change: China's forest carbon uptake 'underestimated'

Climate change: China's forest carbon uptake 'underestimated'

China's aggressive policy of planting trees is likely playing a significant role in tempering its climate impacts.An international team has identified two areas in the country where the scale of carbon dioxide absorption by new forests has been underestimated.Taken together, these areas account for a little over 35% of China's entire land carbon "sink", the group says.The researchers' analysis, based on ground and satellite observations, is . A carbon sink is any reservoir - such as peatlands, or forests - that absorbs more carbon than it releases, thereby lowering the concentration of CO2...

Osiris-Rex: Nasa asteroid mission confident of success

Osiris-Rex: Nasa asteroid mission confident of success

"We really did kind of make a mess."That was Dante Lauretta's take after reviewing the first pictures to come down from following its bid to grab a sample from asteroid Bennu .Dust and grit flew in all directions but that was good news, enthused the University of Arizona professor."Everything that we can see from these initial images indicates sampling success. So in case you can't tell, I'm pretty excited."The principal investigator's team now has to work out precisely how much material Osiris-Rex might have lifted from the surface of 500m-wide Bennu.If it's a kilo or more, it would...

Europe steps up contributions to Artemis Moon plan

Europe steps up contributions to Artemis Moon plan

Thales Alenia Space in Italy will produce Europe's two major contributions to the Lunar Gateway, a US-led space station around the Moon.TAS will build two pressurised sections: one where astronauts can live, and the other on which refuelling and telecoms equipment can be mounted.The UK-arm of TAS will provide the refuelling hardware.The Gateway is intended as a staging post for astronauts as they shuttle back and forth to the Moon's surface.At 40 tonnes, the station is a key part of the American space agency Nasa's Artemis project, which is targeting a human return to the lunar environment...

'The sea-ice is dying': Historic Arctic trip ends

'The sea-ice is dying': Historic Arctic trip ends

The German Research Vessel Polarstern has sailed back into its home port after completing a remarkable expedition to the Arctic Ocean.The ship spent a year in the polar north, much of it with its engines turned off so it could simply drift in the sea-ice.The point was to study the Arctic climate and how it is changing.And expedition leader, Prof Markus Rex, returned with a warning. "The sea-ice is dying," he said."The region is at risk. We were able to witness how the ice disappears and in areas where there should have been ice that was many metres thick, and even at the North Pole - that...

Planet Mars is at its 'biggest and brightest'

Planet Mars is at its 'biggest and brightest'

Get out there and look up!Mars is at its biggest and brightest right now as the Red Planet lines up with Earth on the same side of the Sun.Every 26 months, the pair take up this arrangement, moving close together, before then diverging again on their separate orbits around our star.Tuesday night sees the actual moment of what astronomers call "opposition".All three bodies will be in a straight line at 23:20 GMT (00:20 BST)."But you don't have to wait until the middle of the night; even now, at nine or 10 o'clock in the evening, you'll easily see it over in the southeast," says...

Big Antarctic iceberg edges out to sea

Big Antarctic iceberg edges out to sea

The giant berg A-68 looks finally to be on the move. Recent weeks have seen it shuffle back and forth next to the Antarctic ice shelf from which it broke away. But the latest satellite imagery now indicates the near-6,000 sq km block is swinging out into the Weddell Sea. A wide stretch of clear water has opened up between the berg's southern end and the remaining Larsen shelf structure, suggesting A-68 is set to swing around and head north. This is the direction the Weddell currents should take the iceberg.Polar experts expect the trillion-tonne block to essentially bump along the shelf...

Antarctic iceberg: Giant 'white wanderer' poised to break free

Antarctic iceberg: Giant 'white wanderer' poised to break free

Everybody is fascinated by icebergs. The idea that you can have blocks of frozen water the size of cities, and bigger, sparks our sense of wonder. British astronaut Tim Peake photographed one from orbit that would just about fit inside Central London's ring road. But at 26km by 13km (16 miles by 8 miles), it was a tiddler compared with the berg that is about to break away from the eastern side of the Antarctic Peninsula. A rift has grown across the edge of the Larsen C Ice Shelf. A thin, 5km-long section of the floating shelf is now all that prevents a 6,000-sq-km berg from drifting away...

SpaceX completes launch and landing double bill

SpaceX completes launch and landing double bill

US rocket company SpaceX completed back-to-back launches at the weekend. Late on Friday, it used one of its refurbished Falcon 9 vehicles to put up a Bulgarian satellite from Florida.Then on Sunday, SpaceX lofted another 10 spacecraft for telecommunications company Iridium. This time, the rocket flew out of California.Both missions saw the Falcon first-stages come back to Earth under control to drone ships that had been positioned out on the ocean. It means SpaceX has now had 13 landing successes for those missions it has sought to recover the booster. That said, Friday's first-stage had a...
