If you were able to witness the lunar eclipse on May 15-16, 2022, the view of the dark red Moon was stunning. But what would such an eclipse look like from space?
Wonder no longer. ESA/Italian astronaut Samantha Cristoforetti captured a series of photos of the lunar eclipse from her unique vantage point aboard the International Space Station (ISS).

Be sure to watch the skies on the last morning of May, for a possible Tau Herculid meteor outburst.
If predictions hold true, we may be in for a rare meteor outburst from an obscure meteor shower on May 31st topping a thousand meteors per hour… or we may see nothing at all. Welcome to the wonderful world of meteor shower predictions and prognostications.

Any project manager will tell you that a phased review project system is the way to go. Whether or not you agree with that statement, the process has been widely adopted by space exploration organizations across the globe. They form the basis of many of the best-known projects, and the completion of their phases are events to be celebrated by both the people working on them and the public at large. Now LISA, ESA’s attempt to build a 2.5 million kilometers long interferometer in space, has passed its Feasibility Phase, and is moving on to actually building some prototype technologies.

The InSight Mars lander will cease science operations sometime in the next few months due to a decreasing power supply, mission managers said at a news conference on May 17. Martian dust covering the solar panels has reduced the amount of power to roughly 500 watt-hours per Mars day or sol. When InSight landed in November of 2018, the solar panels produced around 5,000 watt-hours each sol.
“At the end of the calendar year, we do anticipate having to conclude all InSight operations,” said Kathya Zamora Garcia, InSight’s deputy project manager said at the briefing, “not because we want to turn it off but unfortunately we don’t have the energy to run it.”

How will humanity meet its end?
That’s only a depressing question if you think that humanity will go on forever. Alas, nothing lasts forever, and if something could last forever, it probably wouldn’t be our struggling primate species.
But we’ll likely be around for a while yet, pondering things as we do. One of the things we love to ponder is: why don’t we hear from any other alien civilizations?

When Sicilian astronomer Giuseppe Piazzi spotted Ceres in 1801, he thought it was a planet. Astronomers didn’t know about asteroids at that time. Now we know there’s an enormous quantity of them, primarily residing in the main asteroid belt between Mars and Jupiter.
Ceres is about 1,000 km in diameter and accounts for a third of the mass in the main asteroid belt. It dwarfs most of the other bodies in the belt. Now we know that it’s a planet—albeit a dwarf one—even though its neighbours are mostly asteroids.
But what’s a dwarf planet doing in the asteroid belt?

The China National Space Agency (CNSA) has advanced considerably since the turn of the century, boasting new launch vehicles, robotic missions to the Moon and Mars, and a modular space station in orbit (Tiangong). According to various sources, they plan to advance even further in the coming years and decades. Given the tight-lipped nature of the Chinese government and its agencies, much of what we periodically hear is based on snippets of information, gossip, and speculation.
However, in a recent interview with the state-owned CCTV new network, chief designer Huang Zhen confirmed that China’s space agency has established the Crewed Lunar Program Office. This program will consist of additional robotic missions to explore the Moon, followed by crewed missions and the creation of a base camp. Zhen also confirmed that he and his team at the China Association for Science and Technology (CAST) are currently developing the key technologies that will make this happen.

The planet Mars has a lot of intriguing geological features, but a doorway in the side of some sedimentary rock on the flank of Mount Sharp (Aeolis Mons) isn’t one of them. In fact, no such doorway on Mars (supposedly created by aliens) exists. But, there is a break in the rock that really, really does look like one. The fact that it isn’t a real doorway hasn’t stopped a lot of speculation over its appearance in an image snapped by the MastCam on the Curiosity rover on Sol 3466 (May 7, 2022). The plain truth is that the odd-looking feature is really a fracture in ancient layers of sand that have hardened into rock over millions of years. A combination of light, shadow and viewing angle makes it look like a door. But, it’s not.

For the first time in more than half a century, Congress conducted a public hearing into the state of the Pentagon’s study of unidentified aerial phenomena — which is the new name for mysteries once known as unidentified flying objects, or UFOs.
Scott Bray, deputy director of naval intelligence, told a hearing organized by the House Intelligence subcommittee on counterterrorism, counterintelligence and counterproliferation that military reports about UFOs — sorry, I mean UAPs — have been “frequent and continuing.”
Today’s hearing follows up on a Pentagon report that was issued last year and listed 144 UAP sightings that have been reported since 2004. The report pledged to take such sightings more seriously than in the past. “Since the release of that preliminary report, the UAP task force database has now grown to contain approximately 400 reports,” Bray said. “The stigma has been reduced.”
However, the hearing also made clear that the Department of Defense is still keeping mum about the detailed workings of its UAP detection and assessment process due to national security concerns. Bray and the hearing’s other witness — Ronald Moultrie, the under secretary of defense for intelligence and security — deferred a fair number of lawmakers’ questions to the closed session that followed the open hearing.

Each of us is, as it says in Max Ehrmann’s famous poem “Desiderata”, a child of the universe. It speaks metaphorically about our place in the cosmos, but it turns out to be a very literal truth. Our bodies contain the stuff of stars and galaxies, and that makes us children of the cosmos. To be more precise, we are carbon-based life forms. All life on Earth is based on the element carbon-12. It turns out this stuff is a critical gateway to life. So, how did the universe come up with enough of it to make you and me and all the life on our planet? Astrophysicists and nuclear physicists think they have an answer by using a supercomputer simulation of what happens to create carbon. As it turns out, it’s not very easy.
