NASA is currently investigating the feasibility of a “cryobot” probe that would drill through the ice crusts of moons such as Europa and Enceladus to directly detect liquid water and discover the possibility of life beyond Earth.
Apart from Mars, scientists are focusing their efforts on two other candidates: Jupiter’s moon Europa and Saturn’s moon Enceladus.
Compelling evidence indicates the potential existence of subsurface oceans beneath thick layers of water ice on these icy moons.
NASA is currently studying the viability of a “cryobot” mission, which would drill through the ice crusts of these moons to directly detect the existence of liquid water and explore the potential for supporting life forms. This is likely to be a nuclear-powered probe that will be deployed with the assistance of a lander.
When it comes to nightmare scenarios for the United States, a nuclear attack from a foreign power has to rank among the worst possible choices. While the likelihood of such a strike is low, that does not stop experts from trying to prepare for any possibility. A story by Business Insider lists the following six cities as the most likely to be at risk in the vent of a future nuclear attack on the United States:
1) Chicago, Illinois.
2) Houston, Texas
NASA’s maiden mission to explore Saturn’s moon, Titan, has progressed to the next phase of development.
If everything goes as planned, the launch of this car-sized nuclear-powered drone will take place in 2028.
The Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, will move to the final stages of design and development of the Dragonfly drone with NASA’s preliminary design approval.
The world’s biggest experimental nuclear fusion reactor in operation was inaugurated in Japan on Friday, a technology in its infancy but billed by some as the answer to humanity’s future energy needs.
Fusion differs from fission, the technique currently used in nuclear power plants, by fusing two atomic nuclei instead of splitting one.
The goal of the JT-60SA reactor is to investigate the feasibility of fusion as a safe, large-scale and carbon-free source of net energy—with more energy generated than is put into producing it.
The notion of black holes is one that invokes terror and dread. They’re inescapable! They devour everything! Nothing ever comes out!
The accuracy of these beliefs falls on the spectrum of debatable to incorrect. And a pair of physicists has now calculated how proverbial blood might be wrung from the black hole stone. According to Zhan-Feng Mai and Run-Qiu Yang of Tianjin University in China, teeny tiny black holes could theoretically be used as a source of power.
Their calculations find that these ultradense objects could work as rechargeable batteries and nuclear reactors, providing energy on the scale of gigaelectronvolts.
Now that’s forward thinking but it’ll be a long while. But that’s science!
Nothing escapes black holes, but over the decades researchers have worked out ways to get some energy out of them. Some happen naturally, and some energy can be stolen in clever ways. Now, researchers have worked out novel approaches to use black holes as power sources, suggesting that they can be used as either batteries or nuclear reactors.
The assumption of this study is a Schwarzschild black hole – one that has no electric charge or angular momentum. So, it’s neutral and it doesn’t spin. By dropping charged particles on it, the black holes can be made to have a static electric field – and suddenly, you have the makings of a battery.
The team imagined the black hole in a cavity from which electrical charge can be put in and then extracted in a slow controllable way, and with impressive efficiency. This theoretical black battery could transform up to 25 percent of its mass into electrical energy.
New research from North Carolina State University and Michigan State University opens a new avenue for modeling low-energy nuclear reactions, which are key to the formation of elements within stars. The research lays the groundwork for calculating how nucleons interact when the particles are electrically charged.
The work appears in Physical Review Letters.
Predicting the ways that atomic nuclei —clusters of protons and neutrons, together referred to as nucleons—combine to form larger compound nuclei is an important step toward understanding how elements are formed within stars.
Radioisotope Thermoelectric Generators (RTGs) have a long history of service in space exploration. Since the first was tested in space in 1961, RTGs have gone on to be used by 31 NASA missions, including the Apollo Lunar Surface Experiments Packages (ALSEPs) delivered by the Apollo astronauts to the lunar surface. RTGs have also powered the Viking 1 and 2 missions to Mars, the Ulysses mission to the Sun, Galileo mission to Jupiter, and the Pioneer, Voyager, and New Horizons missions to the outer Solar System – which are currently in (or well on their way to) interstellar space.
In recent years, RTGs have allowed the Curiosity and Perseverance rovers to continue the search for evidence of past (and maybe present) life on Mars. In the coming years, these nuclear batteries will power more astrobiology missions, like the Dragonfly mission that will explore Saturn’s largest moon, Titan. In recent years, there has been concern that NASA was running low on Plutonium-238, the key component for RTGs. Luckily, the U.S. Department of Energy (DOE) recently delivered a large shipment of plutonium oxide, putting it on track to realize its goal of regular production of the radioisotopic material.
The recent shipment of 0.5 kg (over 1 lb) of plutonium oxide from the U.S. Department of Energy’s (DOE’s) Oak Ridge National Laboratory to its Los Alamos National Laboratory is critical to realize NASA’s planned future missions. It is also the largest shipment since the DOE issued its report to Congress in 2010 – “Startup Plan for Plutonium-238 Production for Radioisotope Power Systems.” As per this plan, this delivery is a significant step toward achieving the goal of a sustained annual production rate of 1.5 kg (3.3 lbs) by 2026.
Japan’s Nippon Telegraph and Telephone Corporation (NTT) is applying its Deep Anomaly Surveillance (DeAnoS) artificial intelligence tool, originally designed for telecom networks, to predict anomalies in nuclear fusion reactors.
DeAnoS is like a detective, trying to understand which part of the equation is making things weird.
Atomic fusion reactors are at the forefront of scientific innovation, harnessing the enormous energy released by atomic nuclei fusion. This process, which is similar to the Sun’s power source, involves the union of two light atomic nuclei, which results in the development of a heavier nucleus and the release of a massive quantity of energy.
