If you walk across the open yard in front of the Physics, Math and Astronomy building at the University of Texas at Austin, you’ll see a 17-story tower and a huge L-shaped building. What you won’t see is what’s underneath you. Two floors below ground, behind heavy double doors stamped with a logo that most students have never noticed, sits one of the most powerful lasers in the United States.

This shimmering region of star-formation, a close-up of the Trifid Nebula about 5,000 light-years from Earth, was captured in intricate detail by NASA’s Hubble Space Telescope. The colors in Hubble’s visible light image, which marks the 36th anniversary of the mission’s launch on April 24, are reminiscent of an underwater scene filled with fine-grained sediments fluttering through the ocean’s depths.

On Earth, people grip objects to ensure they don’t fall. In space, this process changes: When astronauts hold an object without moving it and then let go, the object doesn’t fall because there is no gravity. But when astronauts move the object any which way, inertia takes the object up, down, left, or right if the hand grip is not steady.

Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein’s theory of relativity, time is not absolute: its passage depends on motion and gravity. But when combined with quantum physics, this relativistic form of time becomes even more counterintuitive.

On April 17, engineers at NASA’s Jet Propulsion Laboratory (JPL) in Southern California sent commands to shut down an instrument aboard Voyager 1 called the Low-energy Charged Particles experiment, or LECP. The nuclear-powered spacecraft is running low on power, and turning off the LECP is considered the best way to keep humanity’s first interstellar explorer going.

Between the Artemis Program, the ESA’s Moon Village, and the Sino-Russian International Lunar Research Station (ILRS), the next step in space exploration is clear: we’re going back to the moon, and this time, to stay! This plan requires significant investment, research, development, and strategies adapted to lunar conditions. In particular, mission planners are concerned about the hazard posed by lunar regolith (aka “moon dust”). In addition to being electrostatically charged, causing it to stick to literally any surface, it is incredibly fine and easily kicked up by rovers and spacecraft as they land and take off.

Scientists have long known that fungi are resilient, but a new study suggests that some strains might survive every step of the long, brutal trip to Mars. In a paper published in Applied and Environmental Microbiology, researchers isolated fungal microbes from NASA cleanrooms—facilities used in the assembly, testing, and launch of spacecraft—that had persisted after decontamination.
