NASA is back with its monthly roundup on what to look out for in the skies over the coming weeks. And there’s plenty to enjoy.
The planets take center stage this month, with July offering a great chance to view Mercury, Mars, Saturn, Venus, and Jupiter.
You’ll be able to see Mercury for a brief period following sunset during the first week of July. Cast your gaze very low in the west 30 to 45 minutes after sundown. Mercury sets within the hour after that, so be sure to carefully pinpoint it before it vanishes from view.
Next up, Mars. The red planet will be visible for the first hour or two after it gets dark. “You’ll find it sinking lower in the sky each day and looking a bit dimmer over the course of the month, as our two planets’ orbits carry them farther apart,” NASA says in its latest roundup video (top), adding that the crescent moon will appear right next to Mars on July 28.
The space agency also notes that July marks the 60th anniversary of the first successful flyby of Mars, by NASA’s Mariner 4 spacecraft. During the mission, Mariner 4 also became the first spacecraft to beam back photos of another planet.
Saturn — the sixth planet from the sun and the second largest planet in our solar system — rises late in the evening this month, and by dawn appears high overhead to the south.
Meanwhile, Venus — our brightest planet — will be shining brightly throughout the month, making it easy to spot. However, you’ll have to wake up early as it’s only viewable a couple of hours before sunrise, toward the east.
Last but not least, Jupiter — the largest planet in our solar system — will be rising in the hour before sunrise and appearing a little higher with each passing day.
NASA also points out that July and August is an excellent chance to view the constellation Aquila, also known as the eagle as its star pattern resembles an eagle in flight.
“This time of year, it soars high into the sky in the first half of the night,” NASA says. adding that to find it, first locate its brightest star, Altair. “It’s one of the three bright stars in the Summer Triangle, which is super easy to pick out during summer months in the Northern Hemisphere. Altair is the second brightest of the three, and sits at the southernmost corner of the triangle.”

After 13 suborbital test flights and more than $15 billion in development costs, SpaceX's Starship has finally reached orbit. The 407-foot megarocket, the most powerful ever built, lifted off from Starbase, Texas, on Monday and delivered its first real payload on it's 14th attempt. The celebration came with an asterisk, though, since SpaceX had to cut the planned 10-hour mission to roughly three hours.

SpaceX is finally ready to give Starship its biggest test yet. The company says the massive rocket's 14th test flight is scheduled for September 22, when it will attempt to put the upper stage into Earth orbit for the first time. The launch is currently pending regulatory approval, with a 75-minute window opening at 7:15 a.m. CT.
Starship has 26 Starlink satellites to deliver
For decades, humanity has looked up at the Moon and wondered what it would be like to live on it. Think sprawling cities, factories, research centers, and permanent human settlements. Unfortunately, there is one fairly fundamental problem with that vision.
A new study published in Frontiers in Space Technologies argues that even the Moon's potentially enormous reserves of frozen water may be nowhere near enough to support city-sized populations sustainably. Researchers Martin Elvis and Jonathan McDowell estimate that the permanently shadowed regions near the lunar poles could contain roughly one billion tons of water. It sounds like an extraordinary amount until you put a million thirsty humans next to it.
