Following the success in 2019 of Bill Nye and the Planetary Society’s solar sail craft LightSail 2, NASA plans to launch its own solar sail project to investigate near-Earth asteroids.
The Near-Earth Asteroid Scout (NEA Scout) is a small satellite around the size of a shoebox that will sail through space powered by sunlight. The hardware will consist of a stainless steel boom structure across which a thin, aluminum-coated plastic sail will be stretched. The total area covered by the sail is around that of a racquetball court, and as photons from the sun bounce off the shiny surface, they will propel the craft forward.
As wacky as this idea sounds — it was made famous by, among others, science fiction author Arthur C. Clarke — it has been shown to work in low-Earth orbit by the LightSail project. Now NASA will take this one step further by deploying a solar sail in deep space.
A U.S.-based expert says swarms of Chinese vessels have dumped human waste and wastewater for years in a disputed area of the South China Sea where they anchor.
“Gorgon’s failure poses a major problem for any oil and gas company betting on CCS to meet net zero,” said Ian Porter, the chairperson of Sustainable Energy Now, WA. “CCS simply does not work at the scale and at the price needed.”
(Bloomberg) — The world’s biggest project to capture and store carbon dioxide isn’t working like it should, highlighting the challenges oil companies face in tackling their greenhouse gas emissions. Chevron Corp.’s system at the $54 billion Gorgon liquefied natural gas export plant in Australi…

CHINA’S NEW THORIUM-BASED NUCLEAR REACTOR is well situated for being adopted for Space applications.
China is slowly but steadily positioning itself to leap ahead of the US Space program. It is doing this without pomp and fanfare, and without the idea of a “space race,” simply based upon what it requires for its future.
1) Recent noteworthy progress on molten salt thorium reactors could be a key component of future Chinese space-worthiness. Originally designed by the USA’s Oak Ridge National Laboratory in the 1960’s, they were planned to be used for nuclear powered strategic bomber planes, before the nuclear submarine concept became adopted as more feasible. They were chosen because they can be miniaturized to the size of an aircraft. By the same token, they could conceivably be used in advanced atmospheric or space propulsion.
2) Recently, China announced successful tests on a new type of aircraft that takes in air from the surrounding atmosphere, ionizes it with electricity, and expels it as exhaust. The only thing needed would be a strong enough on-board electrical supply to supply the huge amount of power required. Only a nuclear power plant could supply that power unless it were to be beamed from ground stations. Such a plane would require no fuel for its entire lifetime. It could also function in any atmosphere, not only Earth’s atmosphere, since it is not based on burning fuel chemically, which requires oxygen. Versions of such air-plasma-breathing thrust could be used as part of the boosting phase of a rocket launch system.
3) A few days ago, China tested part of its fully reusable space plane, which is a vastly superior system to SpaceX’s “Starship” rocket. While Starship uses old-fashioned ballistic rocket technology, the Chinese spaceplane, according to reports that have come out, involves something similar to the Sanger space plane design. An early version of the Space Shuttle design also had this configuration. Instead of the Space Shuttle’s dangerous solid rocket boosters on the side, and its external fuel tank, which is dumped once the fuel is used up, such systems have a second “booster aircraft” which glides to a runway after boosting the upper stage orbiter into its atmospheric launch position. So, there are two vehicles which land on a runway, with only the orbiter going into space. In addition to this, the Chinese are adding “combined cycle” technologies, where more than one type of propulsion is being used on the aircraft. So, perhaps turbojets, and scramjets, and rocket engines will be used as one example of such a configuration.

Military-grade spyware licensed by an Israeli firm to governments for tracking terrorists and criminals was used in attempted and successful hacks of 37 smartphones belonging to journalists, human rights activists, business executives and two women close to murdered Saudi journalist Jamal Khashoggi, according to an investigation by The Washington Post and 16 media partners.
The phones appeared on a list of more than 50000 numbers that are concentrated in countries known to engage in surveillance of their citizens and also known to have been clients of the Israeli firm, NSO Group, a worldwide leader in the growing and largely unregulated private spyware industry, the investigation found.
The list does not identify who put the numbers on it, or why, and it is unknown how many of the phones were targeted or surveilled. But forensic analysis of the 37 smartphones shows that many display a tight correlation between time stamps associated with a number on the list and the initiation of surveillance, in some cases as brief as a few seconds.
Coronavirus Death Toll

Coronavirus death toll and trends — worldometer.
Updated total and statistics, graphs and charts tracking the total number of deaths, deaths per day, and death by country from the Novel Coronavirus (2019-nCoV) originating from Wuhan, China.
A Dallas, Texas, resident who recently returned from Nigeria has tested positive for monkeypox, a rare virus similar to smallpox, local officials said Friday. Though this is the first confirmed case of the virus in the U.S. since 2003, officials said the public should not be concerned.
“While rare, this case is not a reason for alarm and we do not expect any threat to the general public,” Dallas County Judge Clay Jenkins said in a statement from Dallas County’s health department. Because passengers were wearing masks on the flight and in the airport, the health department said, “It’s believed the risk of spread of monkeypox via respiratory droplets to others on the planes and in the airports is low.”
Monkeypox, which is in the same family of viruses as smallpox, is a rare but potentially deadly viral infection that begins with flu-like symptoms and progresses to a rash on the face and body, according to the CDC. It tends to last two to four weeks. People who do not have symptoms are not capable of transmitting the virus, the health department said.
