3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Getty Images NASA has selected two more university student teams to help address real-world aviation challenges, through projects aimed at using drones for hurricane relief and improved protection of air traffic systems from cyber threats. The research awards were made through NASA’s University Student Research Challenge (USRC), which provides student-led teams with opportunities to contribute their novel ideas to advance NASA’s Aeronautics research priorities. As part of USRC, students participate in real-world aspects of innovative aeronautics research both in and out of the l…

NASA/JPL-Caltech NASA’s Perseverance rover captured this view of Deimos, the smaller of Mars’ two moons, shining in the sky at 4:27 a.m. local time on March 1, 2025, the 1,433rd Martian day, or sol, of the mission. In the dark before dawn, the rover’s left navigation camera used its maximum long-exposure time of 3.28 seconds for each of 16 individual shots, all of which were combined onboard the camera into a single image that was later sent to Earth. In total, the image represents an exposure time of about 52 seconds. The low light and long exposures add digital noise, making the image hazy. Many of the white specks seen in the sky are likely noise; some may be cos…

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Sunlight reflects off the ocean surface near Norfolk, Virginia, in this 1991 space shuttle image, highlighting swirling patterns created by features such as internal waves, which are produced when the tide moves over underwater features. Data from the international SWOT mission is revealing the role of smaller-scale waves and eddies.NASA The international mission collects two-dimensional views of smaller waves and currents that are bringing into focus the ocean’s role in supporting life on Earth. Small things matter, at least when it comes to ocean features like waves and eddies. A rece…

2 min read Space Cloud Watch Needs Your Photos of Night-Shining Clouds Noctilucent Clouds observed from Bozeman, MT on 16 July 2009 at 4:29 MDT. The Space Cloud Watch project needs more photos like this one to diagnose changes in our atmosphere! Photo credit: Dr. Joseph A Shaw Noctilucent or night-shining clouds are rare, high-altitude clouds that glow with a blue silvery hue at dusk or dawn when the sun shines on them from below the horizon. These ice clouds typically occur near the north and south poles but are increasingly being reported at mid- and low latitudes. Observing them helps scientists better understand how human activities may affect our atmosph…

Will the Sun Ever Burn Out? We Asked a NASA Expert: Episode 60

1 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Will the Sun ever burn out? Well, the Sun, just like the stars we see at night, is a star. It’s a giant ball of super hot hydrogen. Gravity squeezes it in and it creates energy, which is what makes the Sun shine. Eventually, it will use up all of that hydrogen. But in the process, it’s creating helium. So it will then use the helium. And it will continue to use larger and larger elements until it can’t do this anymore. And when that happens, it will start to expand into a red giant about the size of the inner planets. Then it will shrink back down into a very…
