NASA to explore divergent fate of Earth's mysterious twin with Goddard's DAVINCI+
Although Earth and Venus are similar in size and location, they are very different worlds today. While Earth has oceans of water and abundant life, Venus is dry and fiercely inhospitable. Although it's somewhat closer to the Sun - about 70 percent of Earth's distance - Venus is much hotter, with temperatures at the surface high enough to melt lead. The scorched landscape is obscured by clouds of NASA selects 2 missions to study Venus
NASA has selected two new missions to Venus, Earth's nearest planetary neighbor. Part of NASA's Discovery Program, the missions aim to understand how Venus became an inferno-like world when it has so many other characteristics similar to ours - and may have been the first habitable world in the solar system, complete with an ocean and Earth-like climate.
These investigations are the final A new dimension in the quest to understand dark matter
As its name suggests, dark matter - material which makes up about 85% of the mass in the universe - emits no light, eluding easy detection. Its properties, too, remain fairly obscure.
Now, a theoretical particle physicist at the University of California, Riverside, and colleagues have published a research paper in the Journal of High Energy Physics that shows how theories positing the exis Trashing space begins in low earth orbit
When we think of space, we think big and empty but when it comes to Earth's orbit, it's cluttered with millions of pieces of garbage that we call space junk.
The junk - or space debris - is made up of uncontrollable human-made items that remain in orbit long after they've served their original purpose. The scale of debris ranges from the very large including discarded stages from rocket an Axiom Space signs with SpaceX for 3 more private crew missions to ISS
Axiom Space revealed Wednesday that it has finalized a deal with SpaceX for three additional Dragon flights, on which Axiom would fly its proposed private crews on its next three fully commercial missions to the International Space Station. The landmark agreement between the industry leaders in human spaceflight as well as orbital services and launch, respectively, ensures the nascent commercial Russians end 7-hour spacewalk at International Space Station

Space junk: Houston, we have a problem
When we think of space, we think big and empty but when it comes to Earth's orbit, it's cluttered with millions of pieces of garbage that we call space junk.
The junk—or space debris—is made up of uncontrollable human-made items that remain in orbit long after they've served their original purpose. The scale of debris ranges from the very large including discarded stages from rocket and satellite launches, through to smaller metal pieces such as nuts and bolts, all the way down to particles such as paint flakes.
At its smallest, the space junk may only be one millimeter in size, but there are thousands of pieces bigger than a pizza box causing problems.
According to the latest European Space Agency statistical modeling, there are approximately 34,000 objects greater than 10 centimeters in orbit, but up to 128 million items between one millimeter and one centimeter floating around.
