Ships passing in the night used Morse code sent with lanterns and shutters to communicate. That same basic principle has allowed NASA to communicate with Psyche, its mission to a metal-rich asteroid in the main belt. However, the “light” was a version of heat, and instead of being able to see each other, Psyche is 240 million miles away from Earth. Oh, and the upload rate of the data it sent is still better than old dial-up internet connections that were prevalent not so long ago.

Testing the equipment on an interstellar mission is one of the first things operators do when the spacecraft successfully launches. In some cases, those tests show the future troubles the mission will face, such as what happened to NASA’s Lucy mission a few years ago. However, in some cases, the mission provides us with perspectives we might never have seen before, which was the case for Hera, ESA’s mission to Dimorphos. This asteroid was deflected successfully during NASA’s DART test in 2022.

Cosmology has had several ground-breaking discoveries over the last 100+ years since Einstein developed his theory of relativity. Two of the most prominent were the discovery of the Cosmic Microwave Background (CMB) in 1968 and the confirmation of gravitational waves in 2015. Each utilized different tools, but both lent credence to the Big Bang Theory, which relates to the universe’s formation. However, we still don’t understand a vital part of that formation, and a new review paper by Rishav Roshan and Graham White at the University of Southampton suggests that we might be able to make some headway on our one-second “gap” in knowledge by using our newfound understanding of gravitational waves.

Mining the Moon to extract its resources is a critical step on humanity’s path into the solar system. One of the most common resources on the Moon is considered relatively valuable here on Earth – titanium. At $10,000 a ton, it is one of the more valuable metals used in various industries, such as aerospace and nanotechnology. So, could we utilize titanium from the Moon to supply Earth’s economy with more of this valuable material? That question is the focus of a paper from researchers at Uppsala University in Finland.

Physical infrastructure on the Moon will be critical to any long-term human presence there as both America and China gear up for a sustained human lunar presence. Increasingly, a self-deploying tower is one of the most essential parts of that physical infrastructure. These towers can hold numerous pieces of equipment, from solar panels to communications arrays, and the more weight they can hold in the lunar gravity, the more capable they become. So it’s essential to understand the best structural set-up for these towers, which is the purpose of a recent paper by researchers at North Carolina State University and NASA’s Langley Research Center.

Americans are famously fond of their guns. So it should come as no surprise that a team of NASA scientists has devised a way to “shoot” a modified type of sensor into the soil of an otherworldly body and determine what it is made out of. That is precisely what Sang Choi and Robert Moses from NASA’s Langley Research Center did, though their bullets are miniaturized spectrometers rather than hollow metal casings.

Mission concepts to the outer solar system are relatively common, as planetary scientists are increasingly frustrated by our lack of knowledge of the farthest planets. Neptune, the farthest known planet, was last visited by Voyager 2 in the 1980s. Technologies have advanced a lot since that probe was launched in 1977. But to utilize that better technology, we first need to have a mission arrive in the system – and one such mission is being developed over a series of papers by ConEx Research and University College London.

Continuous human habitation of the Moon is the state aim of many major space-faring nations in the coming decades. Reaching that aim requires many tasks, but one of the most fundamental is feeding those humans. Shipping food consistently from Earth will likely be prohibitively expensive shortly, so DLR, Germany’s space agency, is working on an alternative. This semi-autonomous greenhouse can be used to at least partially feed the astronauts in residence on the Moon. To support that goal, a team of researchers from DLR released a paper about EVE, a robotic arm intended to help automate the operations of the first lunar greenhouse, at the IEEE Aerospace conference in March.

We’ve officially entered a new era of private spaceflight. Yesterday, the crew of Polaris Dawn, a privately funded mission managed by SpaceX, officially performed the first private extra-vehicular activity, commonly known as a spacewalk. The spacewalk was a success, along with the rest of the mission so far. But it’s attracted detractors as well as supporters. Let’s take a look at the mission objectives and why some pundits are opposed to it.

Ask any property inspector, and they’ll tell you one of the maxims of their profession – where there’s moisture, there’s mold. That relationship also holds true for the International Space Station. The interior climate on the ISS is carefully controlled, but if thrown out of whack, potentially dangerous mold could sprout overnight. A new paper by researchers at The Ohio State University explains why – and provides some insights into how we might prevent it if it does happen.
