BNSF: Estimated 230000 gallons of oil spilled in derailment

BNSF: Estimated 230000 gallons of oil spilled in derailment

Almost half the spill - an estimated 100,000 gallons (378,530 liters) - had been contained with booms near the derailment site and an additional boom placed approximately 5 miles (8.05 kilometers) downstream, Williams said. Olson says the city, with a population of almost 3,400, will use the rural water supply until testing by the Iowa Department of Natural Resources confirms the safety of the city's drinking water.

Curiosity snaps photos of thickening haze as Martian dust storm goes global

Curiosity snaps photos of thickening haze as Martian dust storm goes global

Alan Chan's new driving game Red Rover may not be the type of thing in which you blast hostile aliens, but it uses satellite and terrain data from the HiRISE (High Resolution Imaging Science Experiment ) camera on NASA's Mars Reconnaissance Orbiter to create an astoundingly photorealistic experience that could be the next best thing to actually standing on the Red Planet , no space suit required.

SpaceX Wins $130M Air Force Launch Services Contract; Gwynne Shotwell Comments

SpaceX Wins $130M Air Force Launch Services Contract; Gwynne Shotwell Comments

Three months ago, the Air Force awarded a $354.8 million contract to United Launch Alliance , SpaceX's main competitor, for two launches relating to the AFSPC-8 and AFSPC-12 satellite missions. If the SpaceX military mission is successful, the Falcon Heavy "could displace ULA's Delta IV simply on cost grounds", the media outlet reports, citing industry sources. Consulte Mais Informação

Air Force Certifies SpaceX Falcon Heavy Rocket, Awards $130 Million Contract

The Air Force Space Command-52 satellite flight is believed to be the first time that the Falcon Heavy rocket has competed head-to-head with a United Launch Alliance rocket for a military mission, and obviously it came out on top. The announcement did not name the other party, but a report surmised it could be ULA, a joint venture between Boeing and Lockheed Martin . SpaceX's Falcon 9 is about as big as a 21-story building.

Nasa's Curiosity rover captures photos of Mars dust storm

The dust storm has knocked NASA's Opportunity rover offline for want of sunlight. Mars, though, is an ideal place for dust storms to occur. The rover has been exploring Mars since 2004. In a press conference last week, NASA officials said they expect Opportunity will survive the dust storm. While Opportunity is powered by sunlight, which is blotted out by dust at its current location, Curiosity has a nuclear-powered battery that runs day and night. Consulte Mais Informação

Venus Could See Length Of Day Change Due To Weather Phenomenon

Venus Could See Length Of Day Change Due To Weather Phenomenon

With all that in mind, Gizmodo stressed that the researchers did not actually confirm a change in the length of a Venusian day, but rather ran a simulation that hints at that possibility. Simulations showed that the gravitational waves usually appear around noon and quickly disappear with the sunset. The researchers used their model to not only support the prediction that this phenomenon was a Venusian gravity wave, but that it could force the entire planet to fluctuate how it rotates on its ...

Study puts thousands of ENC homes at repeated risk for tidal flooding

Study puts thousands of ENC homes at repeated risk for tidal flooding

Some of the areas expected to be hit the hardest by such flooding are also areas that will likely have more difficulty adapting and recovering because of "long-standing social and economic inequities", the report said . The homes at risk by 2100 now contribute roughly $187 million collectively in annual property tax revenue. The report used Zillow real estate information and the three rising sea level scenarios developed by the National Oceanic and Atmospheric Administration . Consulte Mais Informação

NASA's Mars 'Opportunity' Rover May Be Lost in Massive Dust Storm

NASA's Mars 'Opportunity' Rover May Be Lost in Massive Dust Storm

Opportunity and its twin rover, Spirit, which arrived the same month, both carrying a suite of scientific instruments to study the terrain, operated on opposite sides of the planet. The most recently recorded storm was in 2007. They can quickly balloon into regional storms, and sometimes expand to engulf the entire planet. The most powerful surface winds encountered on Mars would not topple a spacecraft, although they can sandblast dust particles into the atmosphere. Consulte Mais Informação

Ford to Scrap Ontario's Carbon System in Challenge to Trudeau

Ford to Scrap Ontario's Carbon System in Challenge to Trudeau

The PCs will be sworn in June 29 after defeating the Liberals in an election earlier this month, and ending what he called a job-killing carbon tax was one of his major commitments during the campaign. "The gas companies, I'm putting you on notice", he said. If they exceed those limits they must buy allowances at quarterly auctions or from other companies that come in under their limits.
