New Images of Mars From China’s Rover

On May 14^th, 2021, the China National Space Agency (CNSA) achieved another major milestone when the Tianwen-1 lander successfully soft-landed on Mars, making China the second nation in the world to land a mission on Mars and establish communications from the surface. Shortly thereafter, China National Space Agency (CNSA) shared the first images taken by the Tianwen-1 lander.

By May 22^nd, 2021, the Zhurong rover descended from its lander and drove on the Martian surface for the first time. Since then, the rover has spent 63 Earth days conducting science operations on the surface of Mars and has traveled over 450 meters (1475 feet). On Friday, July 9th, and again on July 15th, the CNSA released new images of the Red Planet that were taken by the rover as it made its way across the surface.

WIMPS vs. Axions: What is dark matter?

Dark matter rules every galaxy. But what exactly is it? Astronomers believe it to be some kind of new, exotic particle. You may have heard some terms tossed around, like WIMPs or axions. Let’s explore what those terms actually mean.

Is the Universe a Fractal?

We find examples of fractals everywhere in nature. Tree branches, snowflakes, river deltas, cloud formations, and more. So it’s natural to ask the ultimate question: is the entire universe one giant fractal? The answer is…no, but sorta yes.

Ingenuity is now Mapping the Terrain Around Perseverance

Having eyes in the sky is useful for a variety of activities. Everything from farming to military operations has benefited from the boom in drone usage, as the small aircraft track the progress of crop disease, enemy movements, or how awesome a professor skier looks going down a mountain. Now the benefits of aerial surveillance has spread to other worlds as Perseverance is starting to map out its path with help from Ingenuity.

Don’t Be Surprised if EmDrive Experiments Never Work

Every few years the “EmDrive”, a proposed method of generating rocket thrust without any exhaust, hits the news. Each time, everyone asks: could this be it? Could this be the technological leap to revolutionize spaceflight?

Don’t hold your breath.

Shanghai is About to Open the World’s Largest Astronomy Museum

China has certainly been making its growing power and influence felt in recent years, especially when it comes to the realm of space exploration and science. In the past ten years alone, China has deployed the three space stations with their Tiangong (“Heavenly Palace”) program, unveiled the Long March 5 heavy launch rocket, and sent robotic missions to the far side of the Moon and the surface of Mars.

Here on Earth, facilities like the Five hundred meter Aperture Space Telescope (FAST) illustrate China’s growing accomplishments in space and astronomy. And on Friday (July 16^th), the largest museum in the world dedicated to the study of space – the Shanghai Astronomy Museum – will open its doors. The purpose and design of this museum is to highlight China’s accomplishments in space and astronomy, as well as the country’s future ambitions in space.

Here’s SpaceX’s new Drone Ship: “A Shortfall of Gravitas”

At this point, SpaceX could claim to be both a rocket company and also a maritime shipping company. The company owns a fleet of drone ships for the purposes of providing their rockets with a safe place to retrograde land in the ocean without having to splash down. In the past, they actually had additional ships for fairing catching, Dragon Capsule recovery, and other support efforts. But now, the company welcomed its newest drone landing ship with an announcement by Elon Musk on Twitter. Welcome to the SpaceX: A Shortfall of Gravitas.

How did Supermassive Black Holes Form? Collapsing Dark Matter Halos can Explain Them

We don’t quite understand how the first supermassive black holes formed so quickly in the young universe. So a team of physicists are proposing a radical idea. Instead of forming black holes through the usual death-of-a-massive-start route, instead giant dark matter halos directly collapsed, forming the seeds of the first great black holes.

From the way These Stars Look, a Supernova is Inevitable

Sometimes loud explosions are easier to deal with when you know they’re coming. They are also easier to watch out for. So when astronomers from the University of Warwick found a rare tear-drop shaped star, known as HD265435, they knew they were looking at a potential new supernova waiting to happen. The only caveat – it might not actually happen until 70 million years from now.

According to Elon, Starship Could Chomp up Space Junk

At their South Texas Launch Facility, just outside of the village of Boca Chica, SpaceX is gearing up to test the Super Heavy, the booster element of their Starship launch system. This massive reusable first stage rocket will be responsible for sending the Starship orbital vehicle to space, where it will deliver satellites to orbit, payloads and people to the Moon, and (if all goes as planned) the first human settlers to Mars.

According to a recent statement issued by SpaceX founder Musk Musk, the Starship could also be used to “chomp up debris” in Earth orbit. As usual, the statement was issued via Twitter, where Musk was once again addressing questions posted by followers and fans. The topic arose after Musk shared the latest updates about Starlink, one of a handful of satellite constellations that are bringing broadband internet services to every corner of the planet.
