Exploring Mars with Next-Generation Helicopters

How can scientists and engineers build off the success of NASA’s Ingenuity Mars helicopter to better explore the Red Planet? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as an aerospace executive with more than two decades of research and engineering experience investigated how a next-generation Mars helicopter could conduct groundbreaking science while delivering peak efficiency and performance. This study has the potential to help scientists and engineers develop new methods for exploring Mars with cost-effective and efficient methods. from Universe Today https://ift.tt/63qCfBV via IFTTT

Uranus’ Moons Could Have Cryovolcanism from Potential Interior Oceans

What can cryovolcanism on the dwarf planet Ceres teach us about potential cryovolcanism on Uranus’ five largest moons, which include Oberon, Umbriel, Ariel, Titania, and Miranda? This is what two studies recently presented at the 56th Lunar and Planetary Science Conference hopes to address, as a team of researchers investigated using Ceres as an analog for the potential ocean moons, Umbriel and Oberon, and the likelihood of an impact crater on Umbriel showing evidence of cryovolcanism. These studies have the potential to help researchers better understand the formation and evolution of ocean worlds in the outer solar system and whether they could potentially have life as we know it. from Universe Today https://ift.tt/A2ftP1S via IFTTT

Are Nuclear Propulsion Systems the Future of Space Exploration?

Efforts are underway to develop advanced propulsion systems that can reduce transit times to Mars and other locations in the Solar System. These include nuclear propulsion concepts, which NASA began researching again in 2016 for its proposed "Moon to Mars" mission architecture. In a recent paper, two aerospace innovators reviewed some key nuclear-electric propulsion concepts, their respective advantages, and challenges. In the end, they conclude that nuclear propulsion has the potential to revolutionize space exploration and make humanity "multiplanetary." from Universe Today https://ift.tt/ozp8JKt via IFTTT

How To Power CubeSats Using Deep Learning

Deciding how to power a CubeSat is one of the greatest challenges when designing a modular spacecraft. Tradeoffs in solar panel size, battery size, and power consumption levels are all key considerations when selecting parts and mission architecture. To help with those design choices, a paper from researchers in Ethiopia and Korea describes a new machine-learning algorithm that helps CubeSat designers optimize their power consumption, ensuring these little satellites have a better chance of fulfilling their purpose. from Universe Today https://ift.tt/ejXudxp via IFTTT

Revealing Proxima Centauri's Extreme Flares

In this age of exoplanet discovery, the flaring of red dwarf stars (M-dwarfs) has taken on new importance. M-dwarfs are known to host many terrestrial planets in their putative habitable zones. The problem is the flaring could make their habitable zones uninhabitable. from Universe Today https://ift.tt/ef7LJAP via IFTTT

Its Mission Over, Gaia Rides Off Into the Sunset

No matter where on Earth you stand, if you have a view of the night sky, and if it is dark enough, you can see the Milky Way. The Milky Way is our home, and its faint clouds of light and shadow have inspired human cultures across the globe. And yet, our view of the Milky Way is limited by our perspective. In many ways, we have learned more from other galaxies than from our own. But when the Gaia spacecraft launched in 2013, all of that changed. from Universe Today https://ift.tt/A6fdsq0 via IFTTT

Dark Matter Could Make Planets Spin Faster

Dark matter is a confounding concept that teeters on the leading edges of cosmology and physics. We don't know what it is or how exactly it fits into the Standard Cosmological Model. We only know that its unseen mass is a critical part of the Universe. from Universe Today https://ift.tt/vKWjTx7 via IFTTT

Webb Sees a Young Star Create a Cosmic Tornado

Way back in 2006, the Spitzer Space Telescope (SST) took an infrared look at a strange object called Herbig-Haro 49/50. It's a jet flowing away from a hot young star. The Spitzer image showed a fuzzy blob at the end of the jet. Was it part of the jet, or something more distant? Recently, the James Webb Space Telescope (JWST) focused its infrared eye on the same object and sent home a fantastic snapshot of this cosmic tornado. It also answered the question about the blob: it turns out to be a distant galaxy, itself bursting with hot young stars. from Universe Today https://ift.tt/c8ZXGl6 via IFTTT

When Glaciers Roamed Mars

Mars is cold and dry, but long ago, it was warmer and wetter. Today, its geology is driven by wind and sand, but it was also shaped by water and maybe even glaciers. Glacial activity on Mars was long assumed to be dry, with glaciers frozen right to their beds, scouring the landscape of the Red Planet. But now, researchers think they've found evidence of subglacial melting, where a layer of water forms under the glacier, helping to form various features on Mars. from Universe Today https://ift.tt/ahIiJV7 via IFTTT

Could Venus Host Life? The Venus Life Equation Can Help Us Find Out

What drives us to send probes throughout the Solar System and rovers and landers to Mars? It's not cheap, and it's not easy. It's because we live inside a big, natural puzzle, and we want to understand it. That's one reason. But the main reason for space exploration is to search for life beyond Earth. That our planet could be the only planet to host life is a disquieting thought. from Universe Today https://ift.tt/0N1EaCP via IFTTT

Long-chain Hydrocarbons Found on Mars

The search for evidence of life on Mars just got a little more interesting with the discovery of large organic molecules in a rock sample. The Mars Curiosity Rover, which is digging in the Martian rock beds as it goes along, tested pieces of its haul and found interesting organic compounds inside them. from Universe Today https://ift.tt/it3Ah8G via IFTTT

One Day We Might Seed the Universe With Life. But Should We?

Suppose humanity was faced with an extinction-level event. Not just high odds, but certain-sure. A nearby supernova will explode and irradiate all life, a black hole will engulf the Earth, a Mars-sized interstellar asteroid with our name on it. A cataclysm that will end all life on Earth. We could accept our fate and face our ultimate extinction together. We could gather the archives from libraries across the world and launch them into space in the hopes that another civilization will find them. Or we could build a fleet of arks containing life from Earth. Not people, but bacteria, fungi and other simple organisms. Seed the Universe with our genetic heritage. Of all of these, the last option has the greatest chance of continuing our story. It's an idea known as directed panspermia, and we will soon have the ability to undertake it. But should we? from Universe Today https://ift.tt/5Qwk901 via IFTTT

The Europa Clipper Can Find the Best Landing Sites on the Ocean Moon

There's a well-established paradigm in planetary body exploration. It begins with a flyby, then later an orbiter, and then, if possible, a lander. Previous spacecraft have performed single flybys of Europa, and the Europa Clipper orbiter is on its way to Jupiter's moon Europa for a more detailed orbital study of the frozen moon. Hopefully, a lander will follow. A presentation at the recent Lunar and Planetary Science Conference showed how the Europa Clipper can help find the best landing sites on the icy ocean moon for a future Europa lander. from Universe Today https://ift.tt/te9plwZ via IFTTT

Researchers are Continuing to Scale Up Lightsails That Could Explore the Cosmos

It’s been almost 10 years since Breakthrough Starshot began funding research into interstellar missions. Back then, state of the art meant a tiny lightsail just 0.25mm across, skip forward to today and, following their funded research, a new prototype has been revealed measuring 60mm x 60mm and just 200 nanometres thick! We are not quite able to use it to hop to Proxima Centauri but the technology keeps advancing until that day arrives. from Universe Today https://ift.tt/boLZEJe via IFTTT

There are Space Tornadoes Surrounding the Core of the Milky Way

What happens when you mix clouds of gas and dust, strong outflows, and energetic shock waves at the core of the Milky Way Galaxy? Space tornadoes.

New Insights Into Little Red Dots. An Early Phase of Black Hole Growth

The James Webb Space Telescope has given us a view of the earliest moments of galaxy formation in the Universe. It's also revealed a few surprises.

We aren't entirely sure what they are, but a new study points to an answer. from Universe Today https://ift.tt/sva9j7e via IFTTT

Valkyrie: Exploring Venus With Multiple Small Landers

Shrouded in thick clouds, our erstwhile sister planet Venus is rife with mysteries. Among the Solar System's rocky planets, Venus is the one begging for more exploration.

A New Theory Explains the Surprising Origin of the Planet Mercury

Compared to the other terrestrial planets, Mercury has always been a bit of a mysterious one. It’s internal structure is very different from its planetary siblings with its core accounting for 70% of its overall mass and an unusually thin mantle composed of silicates. One theory suggests a head-on collision between a larger proto-Mercury and a smaller object while another suggests Mercury sideswiped an Earth-mass object. It may be something completely different and a new paper suggests that a grazing collision between two similarly sized bodies led to the formation of the planet we see today. from Universe Today https://ift.tt/EcP3CIr via IFTTT

Researchers Test a Completely Flat Telescope Lens

Telescope optics can be made of mirrors or lenses, but in both cases, they're bulky and need to follow a strict mathematical curve to focus light. Researchers have shown that it's possible to make a completely flat lens that focuses light. Traditionally, this has been done with Fresnel lenses, but they distort colors. Their new technique carves tiny concentric rings into a substrate that matches the wavelengths of different colors, allowing a full-color, in-focus image. from Universe Today https://ift.tt/W9oE1zt via IFTTT

Lunar Samples Identify Exactly When the Moon's Largest Crater Formed

China’s Chang’e-6 mission has been exploring the largest crater on the Moon. It’s known as Aitken Basin and is found at the South Pole of the Moon where craters are permanently shadowed. The crater is a whopping 2,500 km across and measures 10km deep and Chang’e-6 data has revealed that a giant asteroid smashed into the Moon about 4.25 billion years ago. from Universe Today https://ift.tt/eXUGWmE via IFTTT

Europe is Considering a Metal Asteroid Mission of its Own

The European Space Agency is considering a mission to a metal-rich asteroid. The target is Kleopatra, an M-type asteroid with two moons.

The Most Distant Known Galaxy Already Had Oxygen

One of the surprising discoveries of the James Webb Space Telescope (JWST) is that galaxies formed very early in the Universe. JWST has discovered about two dozen galaxies at a redshift of around z = 14, meaning that we see them at a time when the cosmos was just 300-500 million years old. The most distant galaxy, JADES-GS-z14-0, is seen at an age of less than 300 million years. All of these galaxies are rich with stars and have a basic structure similar to what we see in more modern galaxies. This discovery challenged our understanding of galactic evolution. Now a new discovery challenges it even further. from Universe Today https://ift.tt/fiKonzT via IFTTT

The Star Grinder: A Cloud of Black Holes at the Center of the Milky Way

There is a supermassive black hole at the center of our galaxy. There is also a lot of other stuff there as well. Young stars, gas, dust, and stellar-mass black holes. It's a happening place. It is also surrounded by a veil of interstellar gas and dust, which means we can't observe the region in visible light. We can observe stars in the region through infrared and radio, and some of the gas there emits radio light, but the stellar-mass black holes remain mostly a mystery. from Universe Today https://ift.tt/7FI9Y0x via IFTTT

JWST Cycle 4 Spotlight, Part 5: Solar System Astronomy

Welcome back to our five-part examination of Webb's Cycle 4 General Observations program.

LIGO Has Seen Several Intermediate Mass Black Hole Mergers

There are three known types of black holes: supermassive black holes that lurk in the hearts of galaxies, stellar mass black holes formed from stars that die as supernovae, and intermediate mass black holes with masses between the two extremes. It's generally thought that the intermediate ones form from the mergers of stellar mass black holes. If that is true, there should be a forbidden range between stellar and intermediate masses. A range where the mass is too large to have formed from a star but too small to be the sum of mergers. But a new study of data from LIGO suggests that there are black holes in that forbidden range. from Universe Today https://ift.tt/lAJHsnG via IFTTT

How Warp Drives Actually (Might) Work

The World's Oldest Impact Crater Has Been Found in Australia

The surfaces of the Moon, Mercury, and Mars are easily visible and are littered with crater impacts. Earth has been subjected to the same bombardment, but geological activity and weathering have eliminated most of the craters. The ones that remain are mostly only faint outlines or remnants. However, researchers in Australia have succeeded in finding what they think is the oldest impact crater on Earth. from Universe Today https://ift.tt/tv9KeCr via IFTTT

Dust Obscures Our View of the Cosmos. Now it's Mapped Out in the Milky Way

We see the Universe through a glass darkly, or more accurately, through a dusty window. Interstellar dust is scattered throughout the Milky Way, which limits our view depending on where we look. In some directions, the effects of dust are small, but in other regions the view is so dusty it's called the Zone of Avoidance. Dust biases our view of the heavens, but fortunately a new study has created a detailed map of cosmic dust so we can better account for it. from Universe Today https://ift.tt/IzMdCWA via IFTTT

Giant Exoplanets Have Elliptical Orbits. Smaller Planets Follow Circular Orbits

We are so familiar with our solar system that we often presume it is generally how star systems are built. Four little planets close to the star, four large gas planets farther away, and all with roughly circular orbits. But as we have found ever more exoplanets, we've come to understand just how unusual the solar system is. Large planets often orbit close to their star, small planets are much more common than larger ones, and as a new study shows, orbits aren't always circular. from Universe Today https://ift.tt/ucREf2d via IFTTT

Hera Swings Past Mars, Sees Deimos From a New Angle

Gravitational slingshots are now a common part of space missions where the trajectory of a spacecraft is altered using the gravity of another body.

Pallas Has a Very Blue Family

Despite their overall similarities, asteroids are usually pretty distinct from one another. Vesta has a very different spectroscopic profile than Psyche, for example. So it might come as no surprise that another of the main asteroids - Pallas - is in a class all its own except for the 300 or so members of its "family" with similar orbital profiles and spectroscopic lines. A new paper from researchers who were then Visiting Astronomers at NASA's Infrared Telescope Facility (IRTF) in Haiwi'i took a look at members of that family in the infrared for the first time and compared them to a particular Near-Earth object that might have a similar make-up. from Universe Today https://ift.tt/nVvkySF via IFTTT

Galaxies in the Early Universe Seen Rotating in the Same Direction

Astronomers using the James Webb Space Telescope (JWST) have completed a survey of galaxies that reveals their rotation directions with unprecedented clarity. Contrary to expectations that galaxy rotations would be randomly distributed, they discovered a surprising pattern, that most galaxies appear to rotate in a similar direction! One hypothesis suggests the universe itself might have an overall rotation, researchers believe a more plausible explanation though is that Earth's motion through space creates an observational bias, making galaxies rotating in certain directions more detectable than others. from Universe Today https://ift.tt/qGUzJIM via IFTTT
