This year is frequently cherry-picked due to it being the warmest year on record at that time and has been debunked for years. For example, in this article ( Climate Policy Implications of the Hiatus in Global Warming) they make the false claim that global warming has not increased significantly since 1998. When it comes to science the Fraser Institute does not support the consensus of science through the publication of stories that are false or misleading. This article is properly sourced to the National Post. The blog features opinions such as this: Our eighth-best carbon policies. This summary comes from a 54 page report that is well-sourced. News reporting utilizes minimal loaded words such as this: Assessing Canada’s Energy Sector Competitiveness: Collected Essays. The primary focus is on a limited government and Libertarian policy. In review, the website features research, education programs, an economic freedom map, school rankings, and a blog. In addition, the source of our data is always provided.” The Fraser Institute promotes transparency in research – in other words, our methodology is open and clearly explained, and others can replicate our conclusions. The Institute has received donations of hundreds of thousands of dollars from foundations controlled by Charles and David Koch, with total donations estimated to be approximately $765,000 from 2006 to 2016. It also received US$120,000 from ExxonMobil in the 2003 to 2004 fiscal period.Īccording to their about page Fraser Institute’s “research is peer-reviewed and overseen by an Editorial Advisory Board of leading international scholars. It does not accept government grants or payments for research, however, individual donors may claim tax credits for donations and corporate donors may claim tax deductions. The sampling experiment at Bennu shows that it's almost impossible to predict how such a rubble pile might respond to an impact.The Fraser Institute depends on contributions from individuals, corporations, and foundations. Moreover, scientists assume that many asteroids sport a similar "rubble pile" structure: essentially conglomerations of rock, gravel and dirt held together by weak gravitational forces. And even though NASA estimates the chance of collision at 1 in 2,700 between the years 21, Bennu is still one of the most dangerous asteroids currently known. Mike Gravel, and explicitly styled itself as a counterweight to right-wing YouTube phenomenon PragerU. At 1,640 feet wide, a strike by Bennu would cause continent-wide disruption on our planet. The Gravel Institute was born out of the 2020 presidential bid of eccentric late Alaskan Sen. But it's not there."īennu's soft, fluffy nature may complicate a possible future deflection attempt, should astronomers determine the rock threatens to hit Earth.

"We expected that small, fine grains and dust would stick to the large boulders and fill the void space and act as a glue to provide some strength, which would allow the surface to push back against the spacecraft more. "The boulders are very porous and there is a lot of void space between them," Kevin Walsh, a geologist at the Southwest Research Institute in Colorado and lead author of the second study, told. (Image credit: NASA/Goddard/University of Arizona/Lockheed Martin) For comparison, "a typical Earth rock" has a density about six times higher, more like 190 pounds per cubic foot (3,000 kilograms) per cubic meter.Ī second study, based on measurements of forces exerted on the probe during the impact, confirmed those numbers.ĭebris ejected from the surface of asteroid Bennu. The probe sank as deep as 30 inches (70 cm), revealing pristine material that, unlike the asteroid's surface, was unaltered by the steady battering of cosmic rays and the solar wind, the streams of high-energy particles from the sun.įrom the measurements acquired during this repeat visit, Lauretta's team calculated that the density of the surface material was only about 31 to 44 pounds per cubic foot (500 to 700 kilograms per cubic meter), Lauretta said. The surface was soft and flowed away like a fluid." "There clearly was no resistance whatsoever. That's a surprisingly large scar scientists had expected to scoop out a bit about as wide as the sample collector itself, 12 inches (30 centimeters). After touchdown, mission scientists found a brand new 26-foot-wide (8 m) gaping hole in the surface, with displaced rubble and boulders scattered around the site. When the spacecraft first arrived at Bennu, that site, called Nightingale, sat within a 65-foot-wide (20 m) impact crater. Six months after sample collection, in April 2021, the researchers got another glimpse of the OSIRIS-REx touchdown site. The impact aftermath was so unexpected that Lauretta, lead author of one of the two studies, campaigned for the spacecraft to revisit the area to understand what happened.
