NASA has created a map showing how water is distributed on Mars. The water is frozen under the surface of the planet, and some of it is only 30 cm (12 inches) deep. At that depth, astronauts won’t need a machine to access it: just a shovel.Continue reading “NASA Maps Out the Water On Mars. Some Will Be So Easy to Get, You Could Dig it Out With a Shovel”
According to the most widely accepted theory of planet formation (the Nebular Hypothesis), the Solar System began roughly 4.6 billion years ago from a massive cloud of dust and gas (aka. a nebula). After the cloud experienced gravitational collapse at the center, forming the Sun, the remaining gas and dust fell into a disk that orbited it. The planets gradually accreted from this disk over time, creating the system we know today.
However, until now, scientists have wondered how dust could come together in microgravity to form everything from stars and planets to asteroids. However, a new study by a team of German researchers (and co-authored by Rutgers University) found that matter in microgravity spontaneously develops strong electrical charges and stick together. These findings could resolve the long mystery of how planets formed.Continue reading “Planets Started Out From Dust Clumping Together. Here’s How”
Beginning in 2017, the Experimental Sounding Rocket Association (ESRA) and Spaceport America came together to launch a competition known as the Spaceport America Cup. This annual event sees academics and industry experts from around the world gather at the world’s first purpose-built spaceport to collaborate, compete, and inspire young people to become the next generation of aerospace engineers.
At the heart of the competition is the Intercollegiate Rocket Engineering Competition (IREC), where commercial and student teams build and launch-test rockets of their own design. This year’s competition is expected to be very exciting and will see 1,500 international students from over 70 institutions converge on Southern New Mexico this summer to ply their talents and compete for the prestigious Spaceport America Cup!Continue reading “The Spaceport America Cup Joins Crowdsourcing Platform HeroX to Propel Student Innovation!”
NASA has chosen the sampling site for its OSIRIS-REx spacecraft. After narrowing it down to four potential sites and examining them in detail, they’ve settled on one location. Their choice? Nightingale.Continue reading “The Site Has Been Chosen! Here’s Where OSIRIS-REx is Going To Take a Sample from Bennu”
Along with all of their space-exploration, planet-hunting, and astronomy-based endeavours, NASA also keeps a very keen eye on Earth. In fact, they have 18 satellites whose job it is to look only at Earth. And those 18 advanced satellites are helping us understand Earth in unprecedented scientific detail.
And they take pretty pictures, too.Continue reading “North and South America, At Night”
By the time a rocket actually launches, it’s components have been through a ton of rigorous testing. That’s certainly true of NASA’s SLS (Space Launch System) which is the most powerful rocket ever built. That’s right, something is finally going to surpass the Saturn V, the rocket that took Apollo astronauts to the Moon.Continue reading “Watch NASA Test an SLS Tank to Destruction”
There’s a lot of mysterious goings-on at the center of the Milky Way. The supermassive black hole that resides there is chief among them. But there’s another intriguing puzzle there: an unexpected spherical region of intense gamma ray emissions.
A new study suggests that dark matter could be behind those emissions.Continue reading “Dark Matter Could Be A Source of Gamma Rays Coming from the Center of the Milky Way”
While working at the NASA Johnson Space Center during the 1970s, astrophysicist Donald Kessler predicted that collisions between space debris would become increasingly common as the density of space debris increases in orbit around the Earth – creating a cascading effect. Since 2005, the amount of debris in orbit has followed an exponential growth curve, confirming Kessler’s prediction.
Given that the problem is only going to get worse in the coming years, there is a growing demand for technologies that can remove space debris. Following a competitive process, the ESA recently contracted the Swiss startup ClearSpace Today to create the world’s first debris-removing space mission. This mission, known as ClearSpace-1, is expected to launch by 2025 and will help pave the way for more debris removal missions.Continue reading “An Upcoming ESA Mission is Going to Remove one Piece of Space Junk From Orbit”
Spiral galaxies are an iconic form. They’re used in product logos and all sorts of other places. We even live in one. And though it may seem kind of obvious how they get their shape, by rotating, that’s not the case.Continue reading “How Spiral Galaxies Get Their Shape”
