Here is Where Astronauts Might Land on the Moon

In just four days, the inaugural mission of the Artemis Program will lift off from Kennedy Space Center in Florida! Dubbed Artemis I, this mission will see the Space Launch System (SLS) and Orion spacecraft achieve flight together for the first time. The mission will last between 39 and 42 days and consist of the uncrewed Orion flying beyond the Moon, farther than any spaceship has ever traveled, and then looping back around the Moon to return home. This flight, and the crewed Artemis II that will follow, are essentially the dress rehearsal for the long-awaited return to the Moon.

Carbon Monoxide is Plentiful in Nebulae, but Then Disappears When Planets Form. Now we Know Where it Goes!

Protoplanetary disks—those nurseries around young stars where planets form—are filled with gas and dust. In particular, many show a lot of carbon monoxide gas. It’s a handy “tracer” to estimate the mass of a cloud, its composition, and even its temperature. It’s also easy to observe. However, astronomers think there should be more of it than they’re observing in many disks. And that prompted a question: where’s the rest of it?

Godspeed, Uhura: A Bit of Star Trek’s Nichelle Nichols Will Go to Space

Nichelle Nichols, who blazed a trail for Black actors as Lieutenant Uhura on the original “Star Trek,” never got to go to space while she was alive — but her ashes and her DNA are due to reach the final frontier as early as this year.

New Horizons Could Still Have More Adventures Ahead

Remember New Horizons? That plucky little spacecraft that gave us our first up-close looks at Pluto and Arrokoth? Of course, we do! Well, it’s still out there, traveling deeper into the Kuiper Belt. Just because it finished its primary mission doesn’t mean we’re done with it yet.

Want to Live on Mars? Here's Where the Water is

When crewed missions begin to travel to Mars for the first time, they will need to be as self-sufficient as possible. Even when Mars and Earth are at the closest points in their orbits to each other every 26 months (known as “Opposition“), it can take six to nine months for a spacecraft to travel there. This makes resupply missions painfully impractical and means astronauts must pack plenty of supplies for the journey. They will also need to grow some of their food and leverage local resources to meet their needs, a process known as In-Situ Resource Utilization (ISRU).

Colliding Black Holes Provide Another way to Measure Distance in the Universe

We know the universe is expanding, and we have a pretty good idea of how fast it’s expanding, but we don’t know the rate exactly. That’s because of the different methods we have to measure the rate of cosmic expansion keep giving us slightly different results. It’s a nagging problem that bugs astronomers, so while they have worked to ensure current methods are accurate, they have also looked to new ways to measure cosmic expansion. One of these new ways involves gravitational waves.

Astronauts Going to Mars Will Receive Many Lifetimes Worth of Radiation

In a recent study published in Space Physics, an international team of researchers discuss an in-depth study examining the long-term physiological effects of solar radiation on astronauts with emphasis on future astronauts traveling to Mars, to include steps we can take to help mitigate the risk of such solar radiation exposure. The researchers hailed from the United Arab Emirates, New Zealand, India, United States, Italy, Greece, and Germany, and their study helps us better understand the in-depth, long-term health impacts of astronauts during long-term space missions, specifically to Mars and beyond.

Samples From Asteroid Ryugu Contain Bits That Came From Outside the Solar System

Long before our Sun began to form, stars were dying in our part of the galaxy. One of them exploded as a supernova. The catastrophe created minute grains of dust and the force of the explosion blasted through a nearby cloud of gas and dust. That action seeded the cloud with “alien” materials from the dead star. The shock wave from the supernova also caused the cloud to collapse in on itself to create the Sun. The “leftovers” of the cloud became the planets, moons, rings, comets, and asteroids of our solar system.

Gaze Into the Heart of NGC 1365, Captured by Webb

Astrophotographer Judy Schmidt (aka. Geckzilla, SpaceGeck) is at it again! Earlier this month, she released a processed image of the Great Barred Spiral Galaxy (NGC 1365). The James Webb Space Telescope (JWST) recently observed this iconic double-barred spiral galaxy, which resulted in the most-detailed look at this galaxy to date. This time, Schmidt shared a series of images via Twitter that provide a closer look at NGC 1365’s core region, a widefield view that shows the galaxy’s long arms, and lovely animation that shows the galaxy in near- and mid-infrared wavelengths.

The Latest Webb Observations Don’t Disprove The Big Bang, But They Are Interesting

Okay, so let’s start with the obvious. The big bang is not dead. Recent observations by the James Webb Space Telescope have not disproven the big bang, despite certain popular articles claiming otherwise. If that’s all you needed to hear, then have a great day. That said, the latest Webb observations do reveal some strange and unexpected things about the universe, and if you’d like to know more, keep reading.

Rare “Red Sprites” Seen From ESO’s La Silla Observatory in Chile

This new image taken of the skies above Chile’s Atacama Desert near the European Southern Observatory’s (ESO) La Silla Observatory, shows bright red streaks in the sky known as red sprites. Red sprites are large-scale electrical discharges that occur high above thunderstorm clouds, usually triggered by the discharges of positive lightning between an underlying thundercloud and the ground. However, the red sprites appear high in Earth’s atmosphere, sometimes 50-90 km in altitude.

Gravitational Waves Will Give Astronomers a new way to Look Inside Neutron Stars

It’s difficult to study neutron stars. They are light years away and only about 20 kilometers across. They are also made of the most dense material in the universe. So dense that atomic nuclei merge together to become a complex fluid. For years our understanding of the interiors was based on complex physical models and what little data we could gather from optical telescopes. But that’s starting to change.

Were Phobos and Deimos Once a Single Martian Moon That Split up? Not Likely, says New Study

The origin of Phobos and Deimos, the two Martian moons, has been a mystery to astronomers. These two bodies are a fraction of the size and mass of the Moon, measuring just 22.7 km (14 mi) and 12.6 km (7.83 mi) in diameter. Both have a rapid orbital period, taking just 7 hours, 39 minutes, and 12 seconds (Phobos) and 30 hours, 18 minutes, and 43 seconds (Deimos) to complete an orbit around Mars. Both are also irregular in shape, leading many to speculate that they were once asteroids that got kicked out of the Main Belt and were captured by Mars’ gravity.

How Weak Will Astronauts Feel When They First set Foot on Mars After Months in Space?

In the coming decade, in 2033, NASA and China intend to send astronauts to Mars for the first time in history. This presents numerous challenges, ranging from logistical and technical issues to ensuring that astronauts can deal with waste and have enough food and water for the months-long transit to and from Mars. But of course, there’s also the health and safety of the astronauts, who will be spending months traveling through space where they’ll be exposed to cosmic radiation and microgravity. There are even concerns that after months of exposure to microgravity, astronauts will have trouble adapting to Martian gravity.

Mars InSight Doesn’t Find any Water ice Within 300 Meters Under its Feet

Space science doesn’t always go as planned. Sometimes when scientists think they’ve made a remarkable discovery that will make human expansion into the cosmos easier, they are just flat-out wrong. But the beauty of science is that it corrects itself in the presence of new data. The people responsible for planning future Mars missions will have to make just such a correction as new data has come in on the availability of water on the red planet. There’s not as much of it as initially thought. At least not around the equator where InSight landed.

Mars and Moon Dust can be Turned Into Geopolymer Cement. Good Enough for Landing Pads and Other Structures

Materials science has long taken the lead in space exploration research, and it seems to have been getting even more attention than usual lately. That is especially true for building materials. NASA has funded several new research programs to develop new building materials that can do everything from providing structure to future human habs to landing pads for future reusable rocket missions. Now that second goal is one step closer, thanks to researchers at the University of Delaware.

Another of the Lucy Mission’s Asteroids has a Moon

There is still so much we don’t know about the asteroids. Various missions have already been sent to some near Earth and in the asteroid belt, but there are just so many that it is hard to keep track of them all. Lucy, NASA’s mission to the Trojan asteroids, is supposed to help with that, but even it doesn’t know what it is getting into. Apparently, there are even more things to explore than the mission designers initially thought when it launched. Rather than visiting seven asteroids as originally envisioned, the discovery of another asteroid in orbit around Polymede means the mission will be visiting nine asteroids in total.
