Comments Off on Critical climate record satellite program at risk after Congress slashes funding

Scientists all over Earth depend on sea ice data from United States military satellites . But one of those satellites recently broke down – and only three aging ones remain. Even worse, the United States Congress  said a new backup probe had to be dismantled because they reportedly didn’t want to pay to keep it in storage. Almost four decades of essential  Arctic and Antarctic sea ice satellite measurements could soon be disrupted. The National Snow and Ice Data Center (NSIDC) puts together a sea ice record used by scientists worldwide with satellite information. That record is at risk, as a new satellite can’t be launched until at least 2023, according to scientists. Related: Total sea ice levels on Earth lower than ever before recorded Satellites have aided scientists in measuring Earth’s dramatically shrinking sea ice. Over the years, America’s Defense Meteorological Satellite Program (DMSP) has overseen the building of eight F-series satellites monitoring sea ice, but now just three aging probes, DMSP F16, F17, and F18, are operating. And they’re starting to drift out of their orbits. The satellites have lifespans of up to five years – but these three are over eight, 11, and 14 years old. F19 is the satellite that broke, and should have been replaced with F20, which was being stored by the United States Air Force . But it was dismantled in 2016 after Congress cut funding for the program, according to the Scientific American. The Air Force reportedly spent $518 million on F20. NSIDC satellite remote sensing expert David Gallaher said, “This is like throwing away the medical records of a sick patient. Our world is ailing and we have apparently decided to undermine, quite deliberately, the effectiveness of the records on which its recovery might be based. It is criminal.” Scientific American said a Japanese satellite is collecting sea ice data – but it was designed to last five years and is already five years old. A Chinese satellite might offer an alternative – and experts will discuss options at a December meeting of the American Geophysical Union.

Comments Off on Elon Musk wants to build a rocket that can fly you from New York to Shanghai in 30 minutes

Imagine being able to travel from New York to Shanghai in just 30 minutes. If Elon Musk succeeds with his newest plan, a trip of this kind will soon be possible. During Musk’s Space Exploration Technologies Corp. , the entrepreneur revealed his ambition to build the “BFR” – a rocket that could transport anyone anywhere on the planet within 60 minutes. Musk, who has long dreamed of founding a human colony on Mars , is willing to use his own personal assets to fund the futuristic technology.

Posted by Bloomberg Technology on Thursday, September 28, 2017 “If we are going to places like Mars , why not Earth?” said Musk at the 68th International Astronautical Congress, which took place in Adelaide, Australia. Towards the end of Musk’s presentation, an animation played on the screen behind the tech entrepreneur, showing dozens of people getting on a high-speed ferry in New York, boarding the BRF on a platform in the water, then jetting to Shanghai in about 30 minutes. Musk wrote on Instagram: ”Fly to most places on Earth in under 30 mins and anywhere in under 60. Cost per seat should be about the same as full fare economy in an aircraft . Forgot to mention that.” Reportedly, the BFR will contain 40 cabins capable of “ferrying” approximately 100 people at a time. The 46-year-old has admitted in the past that “the major fundamental flaw” in his plans is the financing aspect. With a net worth of approximately $21 billion, the entrepreneur isn’t averse to using his own personal assets to develop the technology. However, money for the BFR will also be raised via contracts with commercial satellite operators, who can use the BFR to carry satellites to orbit, as well as crew and cargo to the International Space Station .

Though the initial plan has changed, the new goal has the craft landing on Mars in 2022, followed by crewed missions in 2024. Via Bloomberg Images via TEDx , Pixabay

Satellites verify San Francisco’s leaning Millennium Tower is sinking

Comments Off on Satellites verify San Francisco’s leaning Millennium Tower is sinking

‘Leaning tower’ isn’t a moniker most people want attached to an inhabited skyscraper , but that’s what people are calling the 58-story Millennium Tower in San Francisco. And for good reason. The European Space Agency recently unveiled (ESA) satellite data which shows not only that the tower is leaning, but it’s sinking – and a lot faster than engineers previously thought. ESA’s Sentinel-1 satellites gathered the data showing the tower filled with luxury condominiums is sinking at a rate of around two inches each year. According to KTVU, that number is about twice what engineers expected. The Millennium Tower has sunk 16 inches since it opened in 2009. Related: New NASA study reveals just how fast New Orleans is sinking Why is the tower sinking? Although ESA says the exact cause is not yet known for sure, “it is believed that the movements are connected to the supporting piles not firmly resting on bedrock.” ESA scientists could see the tower’s movement through combining several radar scans from the satellites. According to ESA, “The technique works well with buildings because they better reflect the radar beam.” The scientists could map other areas in the Bay Area using the satellite data. They saw some buildings were moving along the Hayward Fault, and even noticed an uplift of land near Pleasanton. They think replenished groundwater may have resulted in the uplift. The San Francisco information will benefit researchers as they scrutinize subsidence in other cities of the world. Millennium Tower developers say it’s safe for inhabitants to stay in the leaning tower. But earlier in November, San Francisco City Attorney Dennis Herrera filed a lawsuit against developers as they did not tell buyers the tower is sinking “much faster than expected.” Via KTVU Images via Wikimedia Commons and Copernicus Sentinel data (2015-16)/ESA SEOM INSARAP study/PPO.labs/Norut/NGU

Danish city becomes world’s first to power water treatment plant with sewage

Comments Off on Danish city becomes world’s first to power water treatment plant with sewage

The Danish city of Aarhus is on the cusp of becoming the first city in the world to use energy created from household wastewater and sewage to power its water treatment facilities . The Marselisborg Wastewater Treatment Plant expects to generate more than 192% of the energy it needs to run the plant, which supplies fresh water to 200,000 nearby residents. The excess electricity will be used to power water pumps to distribute the clean water and, if there is any electricity left, it will be funneled back into the utility grid. https://www.youtube.com/watch?v=2P4G0HP08iQ The water treatment facility’s approach to turning sewage into usable electricity centers around biogas . Wastewater and sewage are processed in digesters filled with bacteria, which breaks down the organic materials. Kept at a steady 100.4°F (38°C), the waste produces biogas (mostly methane, although some other gases are also present) that is burned to generate both electricity and heat. While this process is used at many wastewater treatment plants as a means to burn off harmful greenhouse gas emissions , none have attempted to harness that electricity for reuse on such a scale until now. Related: Copenhagen now has more bikes than cars The sewer-power upgrades at Denmark’s Marselisborg Wastewater Treatment Plant cost around $3.19 million to install. Aarhus Water officials believe the new system will pay for itself in just five years’ time thanks to reduced maintenance costs and the added benefit of selling excess electricity back to the power grid. Meanwhile, other cities in Denmark (like Copenhagen) and elsewhere in the world are looking for ways to duplicate the Aarhus system so they too can reap the benefits of recycled wastewater energy.

Comments Off on Journalist to Film Factory Farms from Above Using Drones to Get Around Ag Gag Laws

Footage of what happens on factory farms has horrified people in the past, so much so that several states have made it illegal to document livestock operations. But investigative journalist, Will Potter hopes to get around the “ag gag” laws by using drones to photograph the farms from the air. But he needs help raising the finances to undertake the project so he can pay for the equipment, legal expenses, video production and other equipment he needs to make a short documentary, create an e-book and document abuses at factory farms. His Kickstarter campaign (which ends today) has already raised $48,000, with a promise to match all donations above $45,000.
