Satellite imagery shows Antarctic ice shelf crumbling faster than thought

Antarctica's coastal glaciers are shedding icebergs more rapidly than nature can replenish the crumbling ice, doubling previous estimates of losses from the world's largest ice sheet over the past 25 years, a satellite analysis showed on Wednesday. The first-of-its-kind study, led by researchers at NASA's Jet Propulsion Laboratory (JPL) near Los Angeles and published in the journal Nature, raises new concern about how fast climate change is weakening Antarctica's floating ice shelves and accelerating the rise of global sea levels.

Russia puts Iranian satellite into orbit

Russia launched an Iranian satellite into orbit on Tuesday from southern Kazakhstan, just three weeks after President Vladimir Putin and Supreme Leader Ayatollah Ali Khamenei pledged to work together against the West. The remote Khayyam sensing satellite, named after the 11th Century Persian poet and philosopher Omar Khayyam, was launched by a Russian Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan and entered orbit successfully, Russia's space agency said.
