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.

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.  

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.

There’s more than one way to produce oxygen on Mars. Or at least there is now. After the success of the MOXIE experiment that rode along with Perseverance to the red planet in 2021, another idea to produce one of the most useful gases in the universe has been experimentally proven by an international team of researchers. And they could potentially do it on Mars itself.

Two fundamental factors affect all astrophotography – timing and location. If a camera happens to be at the right place at the right time, it can capture images that have never been seen before. And with the proliferation of cameras throughout the solar system, more and more novel photos will be captured at an ever-increasing frequency. China’s Tianwen-1 probe added to that novel collection to celebrate its second anniversary by taking a shot of Mars’ moon Phobos.

One of the beauties of modern-day space telescopes is that the data they produce, which is eventually wholly released to the public, contains useful information about much more than their primary mission objective. Other astronomers can then sift through the data using their own ideas, and in many cases, their own algorithms. Recently, a team from Poland turned a flare-searching algorithm on TESS’s planet-hunting data, and found an astonishing 25,229 stars with solar flares in the data set.

Within the next decade, several space agencies and commercial space partners will send crewed missions to the Moon. Unlike the “footprints and flags” missions of the Apollo Era, these missions are aimed at creating a “sustained program of lunar exploration.” In other words, we’re going back to the Moon with the intent to stay, which means that infrastructure needs to be created. This includes spacecraft, landers, habitats, landing and launch pads, transportation, food, water, and power systems. As always, space agencies are looking for ways to leverage local resources to meet these needs.
