What's up in the night sky this August?   

On Aug. 9, Mars appears close to the Moon before dawn. Look toward the south, high in the sky, and you can't miss it. On Aug. 12, catch the peak of the annual Perseid meteor shower. When & where to look up: https://t.co/gShGniqN1q https://t.co/5buykpoDLh

RT @NASA_Johnson: It’s Episode 4 of our Mars Monthly series on first Fridays! The ride to Mars will be long, and the vehicle carrying humans will need many features. Listen to what we’ve learned and what to consider for deep space transport on “Houston, We Have a Podcast.” https://t.co/HbQLP7SfMI https://t.co/ftY6OIPaoK

Our #Artemis rocket that will take astronauts to the Moon is close to hot firing all four main engines for the first time. 

As part of the Green Run series of tests, teams finished checking out the @NASA_SLS core stage propulsion elements on Aug. 5: https://t.co/4p0L2OgxTN https://t.co/zgg7eM4WUL

Near, far, wherever you are... @NASAHubble will get the shot! 📸

NGC 4907 glows from 270 million light-years away & shining brightly below the galaxy is a star within the Milky Way. This star seems much brighter as it is 100,000 times closer. Read more: https://t.co/rM6wtQOYB4 https://t.co/TSi8zjdpxE

A @NASAJPL team, in collaboration with @EOS_SG, used satellite-derived data to map the likely extent of damage from the Aug. 4 explosion in Beirut. Maps like this one can help identify badly damaged areas where people may need assistance: https://t.co/osF7y1tOQ3 https://t.co/mamSfRGK4Q
