From a small group of rocket pioneers in 1936 to missions exploring Earth, Mars, the outer planets, and beyond, JPL has helped shape humanity’s understanding of the universe. 90 years later, and we’re still exploring.

Another successful fix ⏤ after 49 years and 16 billion miles! 🔧 Engineers recently turned off devices on Voyager 1 and substituted them with lower-power alternatives. Nicknamed the “Big Bang,” the energy-saving effort will allow the remaining instruments to operate longer.  ½

The Orionid meteor shower, created by tiny pieces of debris from Halley's Comet, peaks on the night of Oct. 21 - 22. Your best chance to see them comes a few hours before dawn, after the bright Moon sets. Find a dark location, give your eyes time to adjust, and look up.

Early risers, you deserve something beautiful. 🌘 On Tuesday, Oct. 6, catch the thin crescent Moon high in the eastern sky before dawn. Just above the Moon, you’ll see the planet Jupiter. Below the Moon, the bright star Regulus will be shining. 1/2

As of Sept. 22, it's officially fall in the Northern Hemisphere…while spring begins in the Southern Hemisphere. 🍁 🌎 💐 That's the September equinox, when the Sun is directly above Earth's equator and day and night are close to equal in length around the world.

What's so cool about the Roman Coronagraph? Well, it's the first *active* coronagraph in space, meaning that it can adjust itself on the fly to help scientists get the clearest glare-free images. The @NASARoman Space Telescope is set to launch on Sunday, Aug. 30!

Tonight, don’t miss the partial lunar eclipse! The Eastern U.S., Canada and South America will get the most complete view, with up to 93% of the Moon in shadow. The eclipse will be partially visible from other areas of North America, Europe, and Africa.
