Construction complete, NASA to test Webb Telescope curvature
Engineers and technicians working on the James Webb Space Telescope successfully completed the first important optical measurement of Webb's fully assembled primary mirror, called a Center of Curvature test. Taking a "before" optical measurement of the telescope's deployed mirror is crucial before the telescope goes into several stages of rigorous mechanical testing. These tests will simulate the violent sound and vibration environments the telescope will experience inside its rocket on it..>> view originalFinding Life On Mars Through Smell? New NASA Instrument Could Do That
The sense of smell has come a long way in science. First plants that can smell explosives and now machines that can smell Martian life.Yes, you read that right. NASA is working on an instrument, which when fitted onboard a rover, will allow it to “sniff” for life on Mars and even on other planets. Called Bio-Indicator Lidar Instrument (BILI), the sensor is based on technology currently used by the U.S. military to remotely check the air in public places for potentially lethal chemicals and toxin..>> view originalCuriosity Mars rover checks odd-looking iron meteorite
The dark, golf-ball-size object in this composite, colorized view from the ChemCam instrument on NASA's Curiosity Mars rover is a nickel-iron meteorite, as confirmed by analysis using laser pulses from ChemCam on Oct. 30, 2016. The grid of …more.>> view originalWhat happened when humans first arrived in Australia?
Scientists often look at the peopling of Australia as a sort of benchmark for when modern humans were spreading out of Africa and establishing populations across the globe. But the details of that story are still hotly debated. Estimates of when the first people arrived on the continent range from 45,000 to 60,000 years ago and researchers debate where these first Australians went next and how they lived. But an artifact-filled ancient rock shelter in the southern interior of Australia may help..>> view originalExplore the 'Jacuzzi of Despair,' a lake so salty it kills almost everything inside
They call it the “Jacuzzi of Despair.”The underwater lake, discovered 3,300 feet below the surface of the Gulf of Mexico, is a pit of super-salty water and dissolved methane that kills any critter unlucky enough to fall inside. The discovery was made last year by a San Pedro-based research vessel, the E/V Nautilus.In the video, scientists excitedly navigate a remotely operated vehicle, the Hercules, above the circular pool. They point out the “pickled crabs” that succumbed to the “Jacuzzi of D..>> view originalElon Musk's SpaceX May Lose Inmarsat Launch Order
Nov. 3, 2016 5:23 a.m. ET LONDON— Elon Musk’s Space Exploration Technologies Corp. may lose a spacecraft launch order from a major customer, Inmarsat PLC, even as the European satellite operator voiced confidence in the rocket company’s ability to return to flight this year. SpaceX, as the rocket company is named, lost one of its Falcon 9 rockets in an explosion during a routine refueling exercise in September at Cape Canaveral Air Force Station in Florida. It destroyed an Isra..>> view originalUN: Huge emissions cuts needed to meet Paris climate goals
By Karl Ritter | AP November 3 at 7:04 AM STOCKHOLM — The world is nowhere near on track to achieve the ambitious temperature goals adopted in the landmark Paris Agreement on climate change, the U.N. said Thursday in a sobering report that warned of a human tragedy unless governments stepped up efforts to fight global warming. The U.N. Environment Program said the world needs to slash its annual greenhouse gas emissions by an additional 12 billion-14 billion metric tons by 2030 to have a cha..>> view originalNavigator, astronomer testify at TMT hearing
HILO — The Thirty-Meter Telescope contested case hearing continued Wednesday at the Grand Naniloa Hotel Crown Room in Hilo with navigator Chad Kalepa Baybayan and astronomer Robert McLaren appearing as witnesses for the University of Hawaii at Hilo. It was the seventh day of hearings, which began Oct. 20 after several pre-conference hearings. Retired judge Riki May Amano is the hearings officer. Baybayan was just the third witness for the university who has been called since hearings started. O..>> view originalHere's how to see the biggest supermoon since 1948
Bigger in fact, than it has appeared at any point in the last 68 years, say scientists. This month's supermoon, the penultimate of the year, will be the biggest so far of the 21st century. We won't see its like again until 2034, so make sure you get a look. A "supermoon" occurs when the moon becomes full on the same days as its perigee, which is the point in the moon's orbit when it is closest to Earth. The term is borrowed from the pseudoscience of astrology but has been adopted by popular cul..>> view original
