What Happened to those CubeSats that were Launched with Artemis I?

NASA made history on November 16th when the Artemis I mission took off from Launch Complex 39B at Cape Canaveral, Florida, on its way to the Moon. This uncrewed mission is testing the capabilities of the Space Launch System (SLS) and Orion spacecraft in preparation for the long-awaited return to the Moon in 2025 (the Artemis III mission). Rather than astronauts, this mission carries a group of mannequins with sensors and has a primary payload consisting of the Callisto technology demonstrator (a human-machine video interface system).

If We’re Going to Get Under the Ice on Europa, How Will We Send a Signal Back to the Surface?

If we send some type of nuclear-powered tunnelbot to Europa to seek life under its icy shield, how will we know what it finds? How can a probe immersed in water under all that ice communicate with Earth? We only have hints about the nature of that ice, what layers it has and what pockets of water it might hold.

Mars Once had Enough Water for a Planet-Wide Ocean 300 Meters Deep

Today, Mars is colloquially known as the “Red Planet” on a count of how its dry, dusty landscape is rich in iron oxide (aka. “rust”). In addition, the atmosphere is extremely thin and cold, and no water can exist on the surface in any form other than ice. But as the Martian landscape and other lines of evidence attest, Mars was once a very different place, with a warmer, denser atmosphere and flowing water on its surface. For years, scientists have attempted to determine how long natural bodies existed on Mars and whether or not they were intermittent or persistent.

What’s the Best Mix of Oceans to Land for a Habitable Planet?

Earth is about 29% land and 71% oceans. How significant is that mix for habitability? What does it tell us about exoplanet habitability?

With JWST Fully Operational Again, we get Images Like This: Saturn’s Moon Titan

On August 24th, a vital instrument aboard the James Webb Space Telescope (JWST) experienced a malfunction that prompted the mission team to take it offline. The problem occurred when the Mid-Infrared Instrument (MIRI) experienced increased friction in one of its wheels while in Medium-Resolution Spectroscopy (MRS) mode. The mission team took MIRI offline while they attempted to diagnose the problem, leaving the observatory to continue making observations in other modes.

A New Instrument Gives the Very Large Telescope an Even Sharper View of the Cosmos

The Very Large Telescope (VLT) at Cerro Paranal in northern Chile, is undoubtedly one of the premier ground-based observatories. But a new infrared instrument recently installed on the telescope has made the VLT even better.

NASA's Report Details a Dark Time in American History but Finds no Direct Evidence That Webb Fired People for Their Sexual Orientation

NASA has announced the release of the James Webb History Report, a document detailing their investigation into the namesake of the next-generation space telescope that took to space on December 25th, 2021. Months before it launched, the observatory became the subject of controversy when it was revealed that Webb was involved in the so-called “Lavender Scare.” After reviewing the relevant documents and collections located by their historians, NASA decided not to rename its flagship observatory.

JWST Detects Signs of Active Chemistry and Clouds in the Atmosphere of Exoplanet WASP-39 b

NASA’s JWST data just keeps on delivering amazing discoveries. Back in July, it observed the exoplanet WASP-39 b and found fingerprints of atoms and molecules and active chemical reactions in its clouds. Now, a team of scientists extends that discovery with a much deeper analysis of the data.

The Milky Way’s Stellar Halo Isn’t a Sphere After All

Our galaxy’s stellar halo is giving astronomers some new food for thought. It turns out everyone thought the halo was spherical. But, it’s not. That’s news to everyone who said it was spherical. According to a new measurement done by a team at Harvard-Smithsonian Center for Astrophysics, it has a tilted, oblong football shape. This all tells astronomers an interesting tale about our galaxy’s ancient history.

Volcanoes are the worst. They’ve caused extinctions on Earth, and probably killed Venus

Is there anything good about volcanoes? They can be violent, dangerous, and unpredictable. For modern humans, volcanoes are mostly an inconvenience, sometimes an intriguing visual display, and occasionally deadly.

A Mission to Venus Could Sample its Atmosphere Directly, Searching for Life

We’ve reported in the past about the Venus Life Finder (VLF) mission, which is currently in the proposal stage but could potentially one day explore the Venusian clouds for signs of life. What exactly that life would look like is anyone’s guess. Therefore, the instrumentation the mission will use to find that life will be critical. Enter Fluid-Screen (FS), a technology developed by a start-up company spun out of Yale by Dr. Monika Weber. It could potentially directly detect life in the Venusian atmosphere – if only it could deal with the sulfuric acid.

Hubble Sees a Dense Cloud of Gas and Dust That’s About to Become a Star

The process of star birth begins in a shroud of gas and dust. Hubble Space Telescope (HST) excels in showing detailed views of these stellar crêches because there’s still a lot to learn about them. Its latest image shows an object called a “dense core”, where a stellar embryo could already exist.

Artemis I has Completed its First Flyby of the Moon

The Orion spacecraft made its first close flyby of the Moon on Monday, November 21, coming as close as 81 statute miles (130 km) from the lunar surface. As the Artemis 1 mission’s uncrewed spacecraft flew past the far side of the Moon, Orion’s orbital maneuvering system engine fired for 2 minutes and 30 seconds to successfully put the capsule into the desired orbit for the mission, called a distant retrograde orbit around the Moon.

Einstein's Predictions for Gravity Have Been Tested at the Largest Possible Scale

According to the Standard Model of Particle Physics, the Universe is governed by four fundamental forces: electromagnetism, the weak nuclear force, the strong nuclear force, and gravity. Whereas the first three are described by Quantum Mechanics, gravity is described by Einstein’s Theory of General Relativity. Surprisingly, gravity is the one that presents the biggest challenges to physicists. While the theory accurately describes how gravity works for planets, stars, galaxies, and clusters, it does not apply perfectly at all scales.

Scroll Through the Universe with This Cool Interactive Map

Johns Hopkins University (JHU) continues to pad its space community résumé with their interactive map, “The map of the observable Universe”, that takes viewers on a 13.7-billion-year-old tour of the cosmos from the present to the moments after the Big Bang. While JHU is responsible for creating the site, additional contributions were made by NASA, the European Space Agency, the National Science Foundation, and the Sloan Foundation.

Many Next-Generation Telescopes are Carried on Balloons. Here's What the Next Decade Holds in Balloon Astronomy

NASA’s Balloon Program Analysis Group recently presented a roadmap to NASA, to guide them on how to plan and fund future balloon astronomy programs. Balloons have been used for over a century to conduct physics experiments, astronomical observations and Earth observing work, but remain relatively unknown to the general public. Balloon astronomy share many advantages with space telescopes, but at a fraction of the cost.

Perseverance has Found a Nice Patch of Sandstone on Mars

NASA’s rolling geology robot shared a great image of sandstone that it found on Mars in Jezero Crater. It’s in a region called “Yori Pass”, which is part of an ancient river delta. Perseverance will take rock samples there for the upcoming Sample Return Mission. They should tell more about what happened with water in this region. And maybe they’ll show evidence of life.

There’s a Cloud of Space Debris Around Earth. Here’s how we Could get a Better Picture of it

As we’ve reported here more than a few times – space debris is becoming more and more of a real problem. We’re not quite at Kessler syndrome levels yet, but with the increased interest in getting things into space, there is a real possibility that might happen in the not-too-distant future. Plenty of potential solutions have been put forward to deal with the problem, but they all face a similar problem at the first step – how to track the debris they’re attempting to eliminate. Enter a new idea from researchers in Iran – using a novel type of radar to detect and track space debris before it becomes a danger.
