20 Years of Uranus Observations by Hubble Show a Changing Planet
In 1986, the Voyager 2 spacecraft made a flyby of Uranus. It gave us the first detailed images of the distant world. What was once only seen as a featureless pale blue orb was revealed to be...well, a mostly featureless pale blue orb. The flyby gave astronomers plenty of data, but the images Voyager 2 returned were uninspiring. That's because Voyager only viewed Uranus for a moment in time. Things change slowly on the ice giant world, and to study them you need to take a longer view.

A New Graduate Project Plans to Make Martian Water Drinkable
Mars exploration technology has seen a lot of recent successes. MOXIE successfully made oxygen from the atmosphere, while Ingenuity soared above the red planet 72 times. However, to date, no one has ever achieved one thing that will be absolutely critical to any long-term presence on Mars - making drinkable water. There have been plenty of ideas on how to do that. Still, NASA recently started funding a Worcester Polytechnic Institute (WPI) graduate student named Lydia Ellen Tonani-Penha to look into the problem under their Space Technology Graduate Research Opportunities (NSTGRO) funding program. Her Project Tethys will examine ways to purify the frozen or liquid brine that Mars is infused with.
Perseverance Watched a Dust Devil Eat Another
NASA's Perseverance was scanning the rim of Jezero Crater when it spotted a Martian dust devil overtake and consume another smaller one. The rover was about a kilometer away from the larger dust devil, which was about 65 meters wide. The smaller one was about 5 meters wide. This isn't Perseverance's first encounter with dust devils. It's seen clusters dancing around it and even captured audio of a dust devil on Mars for the first time.
