Blue Origin has taken some serious steps of late to stay in the commercial space game! Ever since founder Jeff Bezos decided to step down as CEO of Amazon to focus on this brainchild of his, the company has been shaking things up and forging on ahead, hoping to become one of the most competitive and lucrative privately-owned launch services in the world. From the launchpad to the courtroom, they are making their presence felt.
Our solar system is filled with everything from planets to rocky asteroids to small icy bodies beyond Pluto, but surrounding all of it is a diffuse halo of objects known as the Oort cloud. We haven’t directly observed the Oort cloud, but we’re pretty sure it’s there by observing the distribution of comet in our solar system. They can appear from any direction in the sky rather than just along the common plane of known solar system bodies.
Black holes are more than just massive objects that swallow everything around them – they’re also one of the universe’s biggest and most stable energy sources. That would make them invaluable to the type of civilization that needs huge amounts of power, such as a Type II Kardashev civilization. But to harness all of that power, the civilization would have to encircle the entire black hole with something that could capture the power it is emitting.
At the heart of most massive galaxies in our Universe, there are supermassive black holes (SMBH) that are on the order of millions to billions of times the mass of the Sun. As these behemoths slowly consume gas and dust that is slowly fed into their maws, they release tremendous amounts of energy. This leads to what is known as an Active Galactic Nucleus (AGN) – aka. a quasar – which can sometimes send hypervelocity jets of material for light-years.
Three months after touching down on the Martian surface, China’s Zhurong rover has completed its primary mission and is still going strong.
The search for Martian life has been ongoing for decades. Various landers and rovers have searched for biosignatures or other hints that life existed either currently or in the past on the Red Planet. But so far, results have been inconclusive. That might be about to change, though, with a slew of missions planned to collect even more samples for testing. Mars itself isn’t the only place they are looking, though. Some scientists think the best place to find evidence of life is one of Mars’ moons.
Astronomers have spotted the fastest-ever asteroid orbiting Sun — and at times, it gets closer to the Sun than the planet Mercury.
Despite decades of exploration and study, Mars still has its fair share of mysteries. In particular, scientists are still trying to ascertain what happened to the water that once flowed on Mars’ surface. Unfortunately, billions of years ago, the Martian atmosphere began to be stripped away by solar wind, which also resulted in the loss of its surface water over time – although it was not entirely clear where it went and what mechanisms were involved.
It’s no secret that a new Space Race has been brewing over the past few years. This time, rather than being a competition between two federal space agencies, the race has more competitors and is more complicated. In addition to more state competitors, there are also commercial space entities vying for positions and lucrative contracts. Add to that a network of public-private partnerships, and you have Space Race 2.0!

The Milky Way galaxy is our home, and yet in some ways, it is the least understood galaxy. One of the biggest challenges astronomers have is in understanding its large-scale structure. Because we’re in the midst of it all, mapping our galaxy is a bit like trying to map the size and shape of a wooded park while standing in the middle of it.
In November (or early December) of this year, after many excruciating delays, NASA’s James Webb Space Telescope (JWST) will finally launch to space. As the most advanced and complex observatory ever deployed, the James Webb will use its advanced suite of instruments to observe stars, exoplanets, and galaxies in the near and mid-infrared spectrum. In the process, it will address some of the most enduring mysteries about the nature of the Universe.

Japan’s space agency (JAXA) is gearing up for its Martian Moons eXploration (MMX) mission, with plans to have a sample from Mars’ moon Phobos return to Earth by 2029. Mission scientists say they hope to find clues to the origins of Mars two moons, as well as Mars itself, and possibly even traces of past life.
In January of 2021, Elon Musk announced SpaceX’s latest plan to increase the number of flights they can mount by drastically reducing turnaround time. The key to this was a new launch tower that would “catch” first stage boosters after they return to Earth. This would forego the need to install landing legs on future Super Heavy boosters and potentially future Starship returning to Earth.

The Ingenuity helicopter on Mars has now completed its 12th flight, where it acted as a scout, looking ahead for dangerous terrain for it’s partner in crime, the Perseverance rover.
Mars is a lifeless wasteland for more than one reason. Not only are the temperatures and lack of water difficult for life to deal with, the lack of a magnetic field means radiation constantly pummels the surface. If humans ever plan to spend prolonged periods of time on the red planet, they’ll need to support an additional type of life – crops. However, it appears that even greenhouses on the surface won’t do enough to protect their plants from the deadly radiation of the Martian surface, at least according to a new paper published by researchers at Wageningen University and the Delft University of Technology.
The fight over who gets to take the Artemis astronauts back to the Moon continues! It all began when NASA announced that they had awarded the contract for its Human Landing System (HLS), the reusable lunar lander that would ferry the Artemis III astronauts to the lunar surface. This decision did not sit well with the other two finalists, Blue Origin and Dynetics, who appealed the decision because NASA was showing “favoritism.”
