What is the greatest challenge facing humans as we prepare for the first crewed missions to Mars? Solar and cosmic radiation? Atrophying bone and muscle? Growing food? How about laundry? It’s strange but true, right now we don’t have a way to clean laundry in space.

This interesting image from the HiRISE camera on the Mars Reconnaissance Orbiter shows a field of fascinating dunes called barchan dunes. These dunes have formed along a cliff in Chasma Boreale, in the North Pole of Mars.

A memorial spaceflight paying tribute to the cast and crew of the original “Star Trek” TV show has just added another star to the passenger list.

Earlier today Apple announced that its new generation of phones, iPhone 14 and iPhone 14 Pro, will have the Emergency SOS feature. It will allow sending distress messages and sharing location by connecting directly to satellites. So, how exactly it will work?

One of the biggest questions facing astronomers today concerns star formation and its role in the evolution of galaxies. In particular, astronomers are curious whether the process began in the central regions of galaxies, where stars are more tightly bound. Previous observations have shown that numerous galaxies experienced intense periods of star formation in their centers roughly one billion years after the Big Bang. For some time, astronomers have wanted to conduct similar observations of the Milky Way’s Galactic Center to study rapid star formation more closely.

Here’s the Tarantula Nebula like we’ve never seen it before. The James Webb Space Telescope turned its detectors towards the Large Magellanic Cloud about 161,000 lightyears away to take a look at 30 Doradus, more commonly known as the Tarantula Nebula. JWST’s exceptional infrared view has now revealed thousands of never-before-seen young stars in this stellar nursery, as well incredible views of the wispy, dusty filaments and the impressive collection of massive older stars.

Asteroids are commonly thought of as solid balls of rock and metal – a place where Bruce Willis can land and stick a nuke into the middle of it. But as we learn more about them, it is becoming more evident that many asteroids are just piles of rubble held loosely together by gravity. So it might not be too big of a surprise when some of those pieces of rubble fly off of the asteroid itself. But it surprised scientists who first observed the phenomena on the asteroid Bennu when OSIRIS-REx visited it in 2019. Now a team led by researchers at the field museum found a meteorite that shows signs it underwent the same process.

In a joint effort between NASA’s MAVEN spacecraft and the United Arab Emirates’ Emirates Mars mission (EMM), scientists have observed an uncommonly chaotic interaction between the solar wind and Mars’ upper atmosphere, creating a unique ultraviolet aurora. The phenomenon represents an unusual occurrence in Martian space weather, and scientists are excited to take advantage of future collaborations between spacecraft to keep an eye out for repeat events.

In 1982, author James Michener published his sprawling Space Race novel, Space. In it, he describes a fictional Apollo 18 mission to the Moon. While the astronauts are on the surface, the Sun unleashes a huge storm, trapping them outside of their protective capsule. The two men get blasted by lethal amounts of radiation before they can get to safety.

Rice is one of the world’s staple crops. It is regularly eaten by more than half the world’s population. And now, it’s been grown in microgravity, on board the newly launched Chinese Wentian space laboratory.

Green sand might sound like a strange thing to find on the Red Planet, but that is exactly what a new paper from researchers led by a team at Purdue found in images from Perseverance.

Private spaceflight is taking off, though some are going faster than others. As SpaceX preps for its sixth crewed launch on a NASA contract, their rival Boeing has announced that they will be delaying the first crewed flight of their Starliner spacecraft until February 2023.

Reusable rocket engines have become all the rage lately, even as NASA’s continually delayed Artemis I mission attempts to launch with non-reusable technology. Realistically the only way to significantly lower launch costs is to reuse the engines rather than build them from scratch every time. Which is why every fan of space exploration should rejoice that another small start-up company, RocketLab, has successfully retested a rocket that has flown in space.

Sometimes, space probes that have long since ceased sending back data can still usher in new discoveries. That was the case recently when scientists used data from Rosetta, a probe that eventually crashed into comet 67P/Churyumov-Gerasimenko in 2016, to understand what changes occur on a comet’s surface as it continues its spin around the Sun.

Spaceflight can be dangerous – and not just because astronauts are strapped to an ongoing massive explosion for their ascent into orbit. Its long-term effects on the human body are starting to come more clearly into focus, and so far, none of the answers have been good. Now a new study from Mount Sinai Medical Hospital has found that, even on relatively short duration spaceflights, astronauts suffer potentially damaging DNS mutations.

Life on Venus, or the possibility thereof, has been a hot topic as of late. There’s also been plenty of controversies, including the (still disputed) discovery of phosphine, a potential biomarker in the atmosphere. The best way to lay that controversy to rest would be to go there and actually take samples, which at the very least, would help constrain the existence of life in Venus’ cloud layers. And a wide-ranging team from academia and industry hopes to do just that.

Student teams are an underappreciated resource in much of the scientific community. Joining a team working toward a goal while at university, whether for racing solar-powered cars or digging fish ponds in Africa, is an excellent way to sharpen technical and project skills while improving communication and teamwork. The space industry is starting to catch on to these strengths, with student teams developing exciting projects all over the world. A recent entry comes from students at the Delft University of Technology in the Netherlands – a six-legged robot called Lunar Zebro with a unique take on wheels.

The future of satellite communications is almost upon us. SpaceX has signed a deal with T-Mobile to provide the carrier’s customers with text services from its Starlink satellites anywhere in the US starting next year. 

Artemis 1 delayed yet again, a direct image of an exoplanet from Webb, how Starlink will connect directly to phones, Voyager 1 is fixed, and the Crisis in Cosmology continues.

Legendary astronomer Frank Drake has passed away at the age of 92. Known primarily for his Drake Equation — an estimate of the probability of intelligent extraterrestrial life — he pioneered the field of SETI, the Search for Extraterrestrial Intelligence, and was a noted astronomer and astrophysicist. His work and life have left an indelible mark on humanity and given hope and wonder to all our hearts.

We are living in an exciting time, where next-generation instruments and improved methods are leading to discoveries in astronomy, astrophysics, planetary science, and cosmology. As we look farther and in greater detail into the cosmos, some of the most enduring mysteries are finally being answered. Of particular interest are cosmic rays, the tiny particles consisting of protons, atomic nuclei, or stray electrons that have been accelerated to near the speed of light. These particles represent a major hazard for astronauts venturing beyond Earth’s protective magnetic field.
