Planetary exploration, specifically within our own Solar System, has provided a lifetime of scientific knowledge about the many worlds beyond Earth. However, this exploration, thus far, has primarily been limited to orbiters and landers/rovers designed for surface exploration of the celestial bodies they visit. But what if we could explore subsurface environments just as easily as we’ve been able to explore the surface, and could some of these subsurface dwellings not only shelter future astronauts, but host life, as well?Continue reading “Exploring Lava Tubes on Other Worlds Will Need Rovers That Can Work Together”
Musk Suggests That Starship Will Probably Make an Orbital Flight in November
SpaceX Founder and CEO Elon Musk recently took to Twitter and hinted that the much-anticipated Starship—currently undergoing upgrades in preparation for its upcoming maiden flight—could launch as soon as November.
Responding to a question from a curious Twitter account asking about updates for Starship’s orbital flight date, Musk responded, “Late next month maybe, but November seems highly likely. We will have two boosters & ships ready for orbital flight by then, with full stack production at roughly one every two months.” As usual, his tweet garnered thousands of likes and hundreds of retweets.Continue reading “Musk Suggests That Starship Will Probably Make an Orbital Flight in November”

Space Diamonds are Even Harder Than Earth Diamonds
In a recent study published in the Proceedings of the National Academy of Sciences, an international team of researchers led by Monash University in Australia have verified the existence of a rare hexagonal structure of diamond called lonsdaleite, within ureilite meteorites from the inside of a dwarf planet that formed approximately 4.5 billion years ago.
Lonsdaleite is named after Dame Kathleen Lonsdale, a famous British pioneering crystallographer responsible for developing several X-ray methods for studying crystal structures, and was the first woman elected as a Fellow to the Royal Society in 1945. This study holds the potential for further unlocking the secrets of the formation of our solar system, and was conducted with collaboration from RMIT University, the Australian Synchrotron and Plymouth University, and CSIRO.Continue reading “Space Diamonds are Even Harder Than Earth Diamonds”
Flying to (Hypothetical) Planet 9: Why visit it, how could we get there, and would it surprise us like Pluto?
In a recent study submitted to Earth and Planetary Astrophysics, an international team of researchers discuss the various mission design options for reaching a hypothetical Planet 9, also known as “Planet X”, which state-of-the-art models currently estimate to possess a semi-major axis of approximately 400 astronomical units (AU). The researchers postulate that sending a spacecraft to Planet 9 could pose scientific benefits much like when NASA’s New Horizons spacecraft visited Pluto in 2015. But does Planet 9 actually exist?Continue reading “Flying to (Hypothetical) Planet 9: Why visit it, how could we get there, and would it surprise us like Pluto?”
New Animation Shows how the Artemis Missions Will use the Lunar Gateway and a Starship to put Humans Back onto the Moon
A recent YouTube video made by YouTube account, Hazegrayart, combines awesome computer animation, great music, and crisp archived audio recordings to show how NASA’s future Lunar Gateway will function for the upcoming Artemis missions. The archived audio recordings encompass only about a third of the short four and a half minutes of video, with almost the entire length being filled with a very relaxing soundtrack as the viewer is left fixated watching a slow and methodical ballet of spaceships come together at Gateway.Continue reading “New Animation Shows how the Artemis Missions Will use the Lunar Gateway and a Starship to put Humans Back onto the Moon”
What is ISRU, and How Will it Help Human Space Exploration?
As Artemis 1 prepares for its maiden launch with the goal of putting astronauts back on the Moon’s surface within the next few years, the next question is how will astronauts live and survive its surface? Will we constantly ferry all the necessary supplies such as water and food from Earth, or could astronauts learn to survive on their own? These are questions that a discipline known as ISRU hopes to answer both now and in the years to come. But what is ISRU, and how will it help advance human space exploration as we begin to slowly venture farther away from the only home we’ve ever known?Continue reading “What is ISRU, and How Will it Help Human Space Exploration?”
Rocket Lab is Sending its own Mission to Venus to Search for Life
In a recent study published in Instrumentation and Methods for Astrophysics, the private space company, Rocket Lab, outlines a plan to send their high-energy Photon spacecraft to Venus in May 2023 with the primary goal of searching for life within the Venusian atmosphere. The planet Venus has become a recent hot topic in the field of astrobiology, which makes the high-energy Photon mission that much more exciting.
Rocket Lab hopes to build off their recent successful launch of the CAPSTONE mission using its Photon satellite bus, and consists of a CubeSat designed to study the near rectilinear halo orbit (NRHO) around the Moon and its applications for long-term missions such as Gateway.Continue reading “Rocket Lab is Sending its own Mission to Venus to Search for Life”
Another Amazing Image from Webb, This Time it’s Galaxy IC 5332
The James Webb Space Telescope (JWST) continues to both dazzle and amaze with its latest image, this time of Galaxy IC 5332, also known as PGC 71775, which is an intermediate spiral galaxy located approximately 30 million light years away. This comes after JWST released its first images at its full power, which includes the Carina Nebula, Stephan’s Quintet, Southern Ring Nebula, and SMACS 0723, the last of which was the deepest and sharpest image of the distant universe to date.Continue reading “Another Amazing Image from Webb, This Time it’s Galaxy IC 5332”
We’ll be Building Self-Replicating Probes to Explore the Milky Way Sooner Than you Think. Why Haven’t ETIs?
The future can arrive in sudden bursts. What seems a long way off can suddenly jump into view, especially when technology is involved. That might be true of self-replicating machines. Will we combine 3D printing with in-situ resource utilization to build self-replicating space probes?
One aerospace engineer with expertise in space robotics thinks it could happen sooner rather than later. And that has implications for SETI.Continue reading “We’ll be Building Self-Replicating Probes to Explore the Milky Way Sooner Than you Think. Why Haven’t ETIs?”
The Moon Could Have Gathered Some of its Water from the Earth’s Atmosphere
Our Moon is a fascinating world that has captivated us since time immemorial. Long before the first telescope was invented, ancient humans used the Moon as a calendar in the sky, with evidence that lunar timekeeping was around as early as 25,000, 30,000, and even 35,000 years before the present. Long before humanity had written language, lived in organized cities, and worshipped structured religions, the Moon was one of humanity’s first timepieces. It wasn’t until the telescope was invented that our Moon became an object of scientific curiosity, with the sketches by Galileo Galilei giving us a new perspective on our nearest celestial neighbor. As science advanced, so did our understanding of the Moon. While the Apollo missions were successful in teaching us about the geology of the Moon, it wasn’t until 2009 when the LCROSS impact probe onboard the Lunar Reconnaissance Orbiter deliberately crashed into a dark crater on the Moon’s south pole and detected 155 kilograms of water as it flew through the ejecta plume before ultimately crashing into the lunar surface.Continue reading “The Moon Could Have Gathered Some of its Water from the Earth’s Atmosphere”
