Things are getting challenging for the Ingenuity helicopter on Mars. The latest news from Håvard Grip, its chief pilot, is that the “Little Chopper that Could” has lost its sense of direction thanks to a failed instrument. Never mind that it was designed to make only a few flights, mostly in Mars spring. Or that it’s having a hard time staying warm now that winter is coming. Now, one of its navigation sensors, called an inclinometer, has stopped working. It’s not the end of the world, though. “A nonworking navigation sensor sounds like a big deal – and it is – but it’s not necessarily an end to our flying at Mars,” Grip wrote on the Mars Helicopter blog on June 6. It turns out that the controllers have options.

On May 23, 2022, the Juno spacecraft made another close pass of Jupiter, with its suite of scientific instruments collecting data and its JunoCam visible light camera snapping photos all the while. This close pass, called a perijove, is the 42nd time the spacecraft has swung past Jupiter since Juno’s arrival in 2016.

Few things in life captivate us more than looking at images from other planets, no matter how dull these images might seem. This is especially true for Mars, as it’s where we’ve sent the most robots to explore its cold and dry surface. The very first image from the surface of Mars in July 1976 was nothing more than the Viking 1 lander’s footpad and some rocks, but no one cared about these mundane details because we were looking at an image from Mars. We were looking at the surface of another world for the first time in human history, and not only were we captivated by it, but we wanted more.

In and around our planet, there are thousands of comets and asteroids known as Near-Earth Objects (NEOs). Multiple space agencies and government affiliates are responsible for tracking them, especially those known as Potentially Hazardous Asteroids (PHA). These objects are so-designated because they will cross Earth’s orbit and may even collide with it someday. Considering how impacts in the past have caused mass extinctions (like the Chicxulub Impact Event that killed the dinosaurs), future impacts are something we would like to avoid!

While the Mars InSight lander is still waiting for a passing dust devil to clean off its solar panels, it appears the Perseverance rover sees dust devils several times a day.

We’re about to reach a milestone that many thought we would never reach. After years of wrangling, cost overruns, threats of cancellation, and lobbying by the science community, the James Webb Space Telescope is only weeks away from its first images.

We’ve been keeping close track of Ingeniuity’s progress here at Universe Today. Following the little helicopter that could hasn’t always been easy – with almost 30 flights logged covering over 7 kilometers and consistently breaking its own record for longest controlled power flight on another planet, Ingenuity has lived up to every expectation so far. But it’s been hard to understand just what it must feel like to fly through the Martian atmosphere – until now. 

The idea of a mirror universe is a common trope in science fiction. A world similar to ours where we might find our evil doppelganger or a version of us who actually asked out our high school crush. But the concept of a mirror universe has been often studied in theoretical cosmology, and as a new study shows, it might help us solve problems with the cosmological constant.

Are we alone in the Universe? Could there be countless sentient life forms out there just waiting to be found? Will we meet them someday and be able to exchange knowledge? Will we even recognize them as intelligent life forms if and when we see them? Or worse, will they recognize us as intelligent life? When it comes to astrobiology, the search for life in the Universe, we don’t know what to expect. Hence, the speculation and theoretical studies into these questions are so rich and varied!

When stars die they’re often not alone, and for the first time astronomers have found a companion to a supernova, lingering long after its sibling destroyed itself.

The planet Mars is calling to us. At least, that is the impression one gets when examining all the planned and proposed missions to the Red Planet in the coming decade. With so many space agencies currently sending missions there to characterize its environment, atmosphere, and geological history, it seems likely that crewed missions are right around the corner. In fact, both NASA and China have made it clear that they intend to send missions to Mars by the early 2030s that will culminate in the creation of surface habitats.

There’s no question that young solar systems are chaotic places. Cascading collisions defined our young Solar System as rocks, boulders, and planetesimals repeatedly collided. A new study based on chunks of asteroids that crashed into Earth puts a timeline to some of that chaos.

June 2022 offers early risers the chance to trace out the naked eye planets, from Mercury to Saturn.

What do two guys from Ohio, the GAIA mission, a worldwide network of ground-based telescopes, machine learning, and citizen scientists all have to do with each other? Thanks to this interesting combo of people and computers, astronomers now have more than 116,000 new variable stars to study. Until now, they knew of about 46,000 of these stars in the Milky Way Galaxy. They had observed maybe 10,000 or so in other galaxies. The discovery gives astronomers even more chances to study variables and understand why they behave the way they do.

“Where are all the Trojans” is a question valid in both the study of ancient history and the study of exoplanets. Trojan bodies, which share orbital paths with other, larger planets, are prevalent in our solar system – most obviously in the Trojan asteroids that follow Jupiter around on its orbital path. However, they seem absent from any star system found with exoplanets. Now, a team of researchers from the SETI Institute and NASA’s Ames Research Center thinks they have found a reason why.

Astronomy is progressing rapidly these days, thanks in part to how advances in one area can contribute to progress in another. For instance, improved optics, instruments, and data processing methods have allowed astronomers to push the boundaries of optical and infrared to gravitational wave (GW) astronomy. Radio astronomy is also advancing considerably thanks to arrays like the MeerKAT radio telescope in South Africa, which will join with observatories in Australia in the near future to create the Square Kilometer Array (SKA).

How many of what kinds of stars live in other galaxies? It seems like a simple question, but it’s notoriously hard to pin down, because astronomers have such a difficult time estimating stellar populations in remote galaxies. Now a team of astronomers has completed a census of over 140,000 galaxies and found that distant galaxies tend to have heavier stars.

Auroras are some of Earth’s most spectacular natural phenomena. Travelers come from far and wide to see the incredible Northern Lights and wonder at their beauty. Once thought to be magical in nature, most science fans understand that the lights are formed by the solar wind interacting with our magnetosphere. But did you know they also make sounds?

NASA has struck deals with two commercial teams to provide the spacesuits destined for use when astronauts return to the moon by as early as 2025 — and there’s an extra twist that might have sounded alien to the Apollo moonwalkers more than a half-century ago. This time, NASA won’t own the suits.

Dark matter doesn’t really do much of anything in the present-day universe. But in the early days of the cosmos there may have been pockets of dark matter with high enough density that they provided a source of heat for newly forming stars. Welcome to the strange and wonderful world of “dark stars.”

One of the most interesting things we can learn from studying the planets and bodies of our Solar System is how much they have in common. Mars has polar ice caps and features that formed in the presence of water. Venus is similar to Earth in size, mass, and composition and may have once been covered in oceans. And countless icy bodies in the Solar System experience volcanism and have active plate tectonics, except with ice and water instead of hot silicate magma. Another thing they have in common, which may surprise you, is sand dunes!
