NASA to get nuclear-powered rocket, revolutionise space travel

What's a government space agency like the National Aeronautics and Space Administration supposed to do if private companies like SpaceX get all the spacefaring glory? One option is to double down on investments in leading-edge advancements that may not pay off for years. Super-fast and maneuverable nuclear-powered rocket engines are one such technology. Last month, NASA, partnering with the Department of Defense, gave Lockheed Martin Corp. nearly $500 million to build and test one by 2027.

The asteroid that struck Earth around 65 million years ago profoundly impacted the planet's future. While this impact was disastrous, it wasn't the biggest asteroid to ever hit Earth. Researchers have now found the crater of the largest asteroid to ever hit the planet located beneath the surface in New South Wales, Australia. The Deniliquin structure, which is nearly 520 kilometers wide, surpasses the previously known biggest asteroid crater called Vredefort, which was around 300 kilometers wide. The Deniliquin impact likely occurred on Gondwana's eastern part before its continent fragmentation.

Over the past few years, the advance in scientific research has shed light on dinosaurs, and how these mammoth creatures went extinct. The theory, known as the Alvarez hypothesis, claims that an asteroid struck Earth nearly 65 million years ago and wiped out entire species of dinosaurs. This theory is backed by some proof too as scientists have also discovered its impact crater, known as the Chicxulub crater, buried under the Yucatan Peninsula in Mexico. As per the hypothesis, the impact of the asteroid would have caused the formation of huge tidal waves and an impact crater almost 140 km wide. Land material would have splattered into space, changing the Earth into a nuclear winter-like environment and ultimately, it would lead to the demise of dinosaurs and many other species.

Asteroids are space rocks mostly present in the main asteroid belt between the orbits of Mars and Jupiter. Since these bodies are so far, how do NASA and other space agencies track them? Sometimes, interaction with a planet's gravitational field knocks these asteroids off their trajectories and sends them towards a planet like Earth for potential impact. When NASA's telescopes track a new Near-Earth Asteroid (NEA), astronomers measure the asteroid's observed positions in the sky and report them to the Minor Planet Center. The Center for Near-Earth Object Studies (CNEOS) then uses that data to determine the asteroid's most likely orbit around the Sun, according to NASA.

Intel's 12th Gen Alder Lake CPUs might be two years old but they still offer some insane value to performance and with the recent price discounts at various US retailers, they are an even better deal for budget and high-end PC builders.

US space agency NASA's New Horizons spacecraft is again gearing up for an exciting endeavor this fall. While stationed in the outer reaches of the solar system, it plans to undertake an observation of Uranus and Neptune. Earlier, the New Horizons was used to study the dwarf planet Pluto. The mission's team is extending an invitation to the global community of amateur astronomers to join in on this remarkable journey. By observing both ice giants simultaneously, enthusiasts can actively contribute to space science.

Every year there are various space missions conducted to study the mysteries of the solar system. One such mission was launched by NASA nearly 17 years back to study the Sun. The spacecraft, known as the STEREO-A, collected data and was instrumental in unveiling various discoveries over the years. It had a partner too in the form of STEREO-B craft, but communication was lost with it. Now after 17 years, the STEREO-A spacecraft is rushing towards a rendezvous with the Earth. Notably, NASA has taken this opportunity to make STEREO-A further study the Sun from this vantage point in order to collect new information about our closest star.

AMD's top-selling Ryzen 7 7800X3D & Ryzen 7 5800X3D 3D V-Cache CPUs have received a price drop at various retailers, making them an even better buy for gaming enthusiasts.

Scientists have identified the maximum mix of heat and humidity a human body can survive.

With the launch of the iPhone 15 series nearing, new leaks and rumors are surfacing almost every week now. While the iPhone 14 Pro models received plaudits for the fancy new Dynamic Island last year, the standard iPhone 14 models left a lot to be desired. But things could change this year as Apple is reportedly planning to bring Dynamic Island and USB Type-C to even the vanilla iPhone 15 variants. Amidst reports of a smartphone slump, it could be just what Apple needs to persuade more people to buy these devices.
