Early this morning, from their Launch Site One facility in West Texas, Blue Origin made history as it conducted the first crewed flight of its New Shepard launch vehicle. The crew consisted of four commercial astronauts: Blue Origin and Amazon founder Jeff Bezos, his brother Mark Bezos, aerospace pioneer Wally Funk, and 18-year old student from The Netherlands Oliver Daemon.Continue reading “What’s Next for Blue Origin After Today’s Successful Flight?”
On the anniversary of the first Moon landing, Blue Origin became the second commercial space company in just nine days to send people just past the edge of space. During the seemingly flawless 10 minute and 10 second flight, the four passengers on board the New Shepard rocket whooped with glee and exhilaration. The crew included Blue Origin and Amazon founder Jeff Bezos, his brother Mark, and the oldest and youngest people to ever fly to space.
Wally Funk, an 82-year-old pioneering female aviator and member of the so-called “Mercury 13” women astronaut-hopefuls made the flight, along with Oliver Daemen, an 18-year-old Dutch physics student.Continue reading “Blue Origin Successfully Launches the Oldest and Youngest Person to Ever go to Space (oh, and Jeff Bezos too)”
Update: Hubble took its first picture since it went into safe mode on June 13th! More info here.
On Sunday, June 13th, the Hubble Space Telescope gave the astronomical community a fright when its payload computer suddenly stopped working. This prompted the main computer to put the telescope and its scientific instruments into safe mode. What followed was many tense weeks as the operations team for the HST tried to figure out what the source of the problem was and come up with a strategy for turning Hubble back on.
On Friday, July 17th, after more than a month of checking, re-checking, and attempted restarts, the operations team for Hubble identified the root of the problem and restored power to the telescope’s hardware and all of its instruments. Science operations can now resume, and the pioneering space telescope that gave us over thirty years of dedicated astronomy, cosmology, and astrophysics, still has some life in her!Continue reading “Good News! NASA Announces that they have Fixed Hubble!”
Ever since the announcement last September that astronomers found evidence of phosphine in the clouds of Venus, the planet has been getting a lot of attention. It’s not surprising. Phosphine is a potential biosignature: On Earth, it is produced by microbial life. Might a similar biological process be taking place in the skies of our sister planet? It’s a tantalizing prospect, and is definitely worth examining closely, but it’s too early to be sure. Microbes aren’t the only way to get phosphine. A new paper published on July 12th in the Proceedings of the National Academy of Science suggests that volcanism might instead be to blame for the strange chemistry in the Venusian cloud tops.Continue reading “Volcanic Activity on Venus Could Explain Phosphine”
We know of four fundamental forces of nature, with no signs of a fifth. But dark matter and dark energy make up over 90% of all the contents of the universe. So the question remains: could there be a fifth force hiding in the “dark sector” of our universe?Continue reading “Where can we find a fifth force of nature?”
As of 2020, there were over 19,000 pieces of individually tracked space junk in orbit above the Earth. Of those, a mere 2,200 were operational satellites. As more and more satellites go up, the risk of collisions increases. And what are governments doing to stop it? Basically, nothing.Continue reading “We Need to Fix Space Junk Before It’s Too Late”
Summertime means it’s time to play ball! But what would it be like to play ball on various locations across our Solar System? Planetary scientist Dr. James O’Donoghue has put together a fun animation of how quickly an object falls on to the surfaces of places like the Sun, Earth, Ceres, Jupiter, the Moon, and Pluto.Continue reading “Fantastic Visualization Shows What Would Happen if you Dropped a Ball Across the Solar System”
On May 14th, 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 22nd, 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.Continue reading “New Images of Mars From China’s Rover”
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.Continue reading “WIMPS vs. Axions: What is dark matter?”
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.Continue reading “Is the Universe a Fractal?”
