NASA, US Space Force Establish Foundation for Broad Collaboration
WASHINGTON, Sept. 22, 2020
WASHINGTON, Sept. 22, 2020 /PRNewswire/ — While advancing plans for unprecedented lunar exploration under the Artemis program, NASA also is building on a longstanding partnership with the Department of Defense with a new memorandum of understanding announced today by NASA Administrator Jim Bridenstine and U.S. Space Force (USSF) Chief of Space Operations Gen. John “Jay” Raymond.
The agreement, discussed during a Sept. 22 Mitchell Institute virtual event, commits the two organizations to broad collaboration in areas including human spaceflight, U.S. space policy, space transportation, standards and best practices for safe operations in space, scientific research, and planetary defense.
“NASA’s partnerships are vital to ensuring America continues to lead the world in the peaceful uses of outer space,” Bridenstine said. “This agreement with the U.S. Space Force reaffirms and continues
Using various space observatories, Italian astronomers have investigated an X-ray binary source known as IGR J18214-1318. Results of the study, detailed in a paper published September 14 on the arXiv pre-print server, provide important information about the properties of this system, shedding more light into its nature.
X-ray binaries consist of a normal star or a white dwarf transferring mass onto a compact neutron star or a black hole. Based on the mass of the companion star, astronomers divide them into low-mass X-ray binaries (LMXBs) and high-mass X-ray binaries (HMXBs).
IGR J18214-1318 is an HMXB detected with the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) satellite in 2006. The object is associated to USNO-B1.0 0766-0475700—most likely a star of spectral type O9I.
The essential parts of an economy are intertwined by their very nature. There’s no point in having a food market if there are no farmers to supply food. But there’s no point in growing food until there are markets where you can sell it. And what is the right moment to go into the “food transportation” business, carting the freshly harvested produce from the field to the store? We’ve seen this in our own era: What was the point in creating high-speed internet service if there was no content online that required such speeds? Why bother creating YouTube if no one has the bandwidth to watch and upload videos easily?
This is exactly the moment we’re in with human space travel. Why bother creating the technology to launch people into space when there’s nowhere in particular to go? But why create destinations in space when there’s no affordable way to
For decades, nuclear engineers have dreamt up new formulas, shapes and sizes for the radioactive fuel that powers the reactors of the world’s nuclear power plants (our greatest source of zer0-carbon electric power). Today most of what’s used for reactor fuel is enriched uranium. In the future, it’s looking ever more likely that fuel compositions will shift toward the very promising thorium.
A potential breakthrough: The United States Department of Energy (DOE) Idaho National Laboratory (INL) and the Nuclear Engineering & Science Center at Texas A&M have partnered with Clean Core Thorium Energy (CCTE) to fabricate a new type of nuclear fuel, called “Advanced Nuclear Energy for Enriched Life”, or ANEEL.
In a statement, Chairman Simon Thompson vowed the company would “never again” allow this type of destruction to take place. Rio Tinto has promised to act “in ways that are sensitive and responsive to the values and expectations of Traditional Owners and Indigenous communities.”
The company has an opportunity to make good on that commitment by preventing the destruction of a site considered sacred by Indigenous people here in the United States. Rio Tinto holds controlling interest in Resolution Copper LLC, co-founded with another Anglo-Australian firm, BHP. Resolution Copper is developing a mine in southeastern Arizona to exploit one of the world’s largest-known untapped copper deposits. The copper ore lays under a tranquil, high-elevation expanse known as Oak Flat.
To the nearby San Carlos Apache Tribe, Oak Flat is holy ground. There are ancient petroglyphs on some of Oak Flat’s rock walls. In addition to evidence of shelters and cooking
NASA is still targeting the moon’s south pole for a crewed landing in 2024 — but that timeline will be difficult to achieve if Congress doesn’t open its purse strings, and fast, agency chief Jim Bridenstine said.
During a presentation with NASA’s Lunar Exploration Analysis Group last Monday, Bridenstine seemed to suggest that the agency is open to a more equatorial site for the 2024 touchdown, a key milestone in NASA’s Artemis program of crewed lunar exploration.
That would be a big shift for NASA, which has long stressed that the first crewed moon landing since the Apollo days would come near the south pole, where lots of water ice lurks on permanently shadowed crater floors. But Bridenstine just clarified that his earlier words about the 2024 mission, known as Artemis 3, were purely hypothetical.
