Well Water Likely Available Across Mars (behindtheblack.com)
schwit1 quotes Behind the Black: A science paper released today and available for download [pdf] cites evidence from about two dozen deep impact craters located from the equator to 37 degrees north latitude that Mars has a ground ice table at an elevation that also corresponds to other shoreline features.
The paper calls this evidence of "planet-wide groundwater" with elevations that "notably coincide with the elevation of some ocean shorelines proposed by previous authors."
Science writer Robert Zimmerman adds that "The evidence suggests that this deep groundwater water table (as ice) almost certainly still exists at all latitudes, though almost entirely underground...
"All you will have to do is dig a well..." -
Chinese Space Official Seems Unimpressed With NASA's Lunar Gateway (arstechnica.com)
schwit1 shares a report from Behind The Black: At a science workshop in Europe this week, Chinese space officials made it clear that they found the concept of NASA Lunar Orbiting Platform-Gateway (LOP-G) to be unimpressive and uninteresting. Moreover, they said that while it appears we will be delaying our landings on the Moon for at least a decade because of LOP-G, they will be focused on getting and building a research station on the surface, right off the bat.
[From a report via Ars Technica:] "Overall, [Pei Zhaoyu, who is deputy director of the Lunar Exploration and Space Program Center of the China National Space Administration], does not appear to be a fan of NASA's plan to build a deep space gateway, formally known as the Lunar Orbital Platform-Gateway, at a near-rectilinear halo orbit. Whereas NASA will focus its activities on this gateway away from the Moon, Pei said China will focus on a 'lunar scientific research station.' Another slide from Pei offered some thoughts on the gateway concept, which NASA intends to build out during the 2020s, delaying a human landing on the Moon until the end of the decade at the earliest. Pei does not appear to be certain about the scientific objectives of such a station, and the deputy director concludes that, from a cost-benefit standpoint, the gateway would have 'lost cost-effectiveness.'" -
Amateur Astronomer Discovers Long-Dead NASA Satellite Has Come Back To Life (behindtheblack.com)
schwit1 shares a report from Behind The Black: In his hunt to locate Zuma, an amateur astronomer has discovered that a long-dead NASA satellite, designed to study the magnetosphere, has come back to life. IMAGE went dead in 2005, and though NASA thought it might come back to life after experiencing a total eclipse in 2007 that would force a reboot, no evidence of life was seen then. It now appears that the satellite came to life sometime between then and 2018, and was chattering away at Earth waiting for a response. NASA is now looking at what it must do to take control of the spacecraft and resume science operations. Zuma is the secret U.S. government payload that was launched by SpaceX earlier this month and reportedly lost. As for why Scott Tilley -- the amateur radio astronomer -- decided to have a look for the present of secret military satellites, Ars Technica reports that he apparently does this semi-regularly as a hobby and, in this case, was inspired by the Zuma satellite. -
The Recent Changes In Earth's Magnetic Field (esa.int)
Europe's Swarm constellation of satellites have documented bigger-than-expected changes that have been occurring in the Earth's magnetic field. Earlier this year SpaceWeather.com reported that the data show clearly that "the field has weakened by about 3.5% at high latitudes over North America, while it has strengthened about 2% over Asia. The region where the field is at its weakest -- the South Atlantic Anomaly -- has moved steadily westward and weakened further by about 2%. These changes have occurred over the relatively brief period between 1999 and mid-2016."
Science writer Robert Zimmerman reports: It was already known that the field has weakened globally by about 10% since the 19th century. These changes appear to be part of that generally weakening. Some scientists have proposed that this is the beginning of an overall flip of the magnetic field's polarity, something that happens on average about every 300,000 years and last occurred 780,000 years ago. At the moment, however, we have no idea if this theory is correct. -
Apollo 11 Moon Rock Bag Belongs To Buyer, Not NASA, Judge Rules (behindtheblack.com)
schwit1 quotes a report from Behind The Black: A federal judge has ruled that NASA has no right to confiscate an Apollo 11 lunar rock sample bag that had been purchased legally, even though the sale itself had been in error. CollectSPACE.com reports: "Judge J. Thomas Marten ruled in the U.S. District Court for Kansas that Nancy Carlson of Inverness, Illinois, obtained the title to the historic artifact as 'a good faith purchaser, in a sale conducted according to law.' The government had petitioned the court to reverse the sale and return the lunar sample bag to NASA. 'She is entitled to possession of the bag,' Marten wrote in his order." This court case will hopefully give some legal standing to the private owners of other artifacts or lunar samples that NASA had given away and then demanded their return, decades later. Space.com's report adds: "The zippered cloth pouch, which was labeled in bold black letters 'Lunar Sample Return,' was used on July 20, 1969, as an 'outer decontamination bag' to protect the first moon rocks retrieved from the surface of the moon as they were delivered to Earth by Apollo 11 astronauts Neil Armstrong, Buzz Aldrin and Michael Collins. Carlson purchased the bag for $995 in February 2015, at a Texas auction held on behalf of the U.S. Marshals Service. The bag had been forfeited along with other artifacts found in the home of Max Ary, a former curator convicted in 2006 of stealing and selling space artifacts that belonged to the Cosmosphere space museum in Hutchinson, Kansas." -
EPA's Gasoline Efficiency Tests Provide No Valid Information At All (hotair.com)
schwit1 writes from a report via Behind The Black: The tests the EPA uses to establish the fuel efficiency of cars are unreliable, and likely provide no valid information at all about the fuel efficiency of the cars tested. Robert Zimmerman reports from Behind The Black: "The law requiring cars to meet these fuel efficiency tests was written in the 1970s, and specifically sets standards based on the technology then. Worse, the EPA doesn't know exactly how its CAFE testing correlates with actual results, because it has never done a comprehensive study of real-world fuel economy. Nor does anyone else. The best available data comes from consumers who report it to the DOT (WARNING: Source may be paywalled) -- hardly a scientific sampling. Other than that, everything is fine. Companies are forced to spend billions on this regulation, the costs of which they immediately pass on to consumers, all based on fantasy and a badly-written law. Gee, I'm sure glad we never tried this with healthcare!" -
Taxpayer Subsidies To ULA To End
schwit1 writes Because it has concluded that they make it impossible to have a fair competition for contracts, the Air Force has decided to phase out taxpayer subsidies to the United Launch Alliance (ULA). The specific amounts of these subsidies have been effectively buried by the Air Force in many different contracts, so we the taxpayers really don't know how much the are. Nonetheless, this decision, combined with the military report released yesterday that criticized the Air Force's over-bearing and restrictive certification process with SpaceX indicates that the political pressure is now pushing them hard to open up bidding to multiple companies, which in turn will help lower cost and save the taxpayer money. -
Trouble In Branson-Land, As Would-Be Space Tourists Get Antsy Over Delays
schwit1 (797399) writes "Rumors are flying that some of the individuals who gave Virgin Galactic deposits for space tourism flights on SpaceShipTwo are demanding their money back. It appears that the most recent delay, revealed by Branson on David Letterman, is the cause." How much would you pay to go to space, if the ticket was only good starting 10 years from now? How about 20? How about, as Branson claims, if it was early next year?
