Venus’ greatest elongation is now visible!
When a planet is at its greatest elongation, we observe the greatest visual separation between the planet and the Sun, as seen from Earth – making it an ideal time for viewing.
This weekend is a great time to catch Venus, especially through a telescope!

In its 14 years on Mars, the Curiosity rover has taken more than 700,000 images, but this one is special – because it was one of the first.
Happy landiversary, Curiosity!
JPL engineers have freed up power on Voyager 2 by simultaneously turning off certain devices and substituting them with lower-power alternatives.

We're taking your questions now!
Our spacecraft have been on the surface and in the skies of Mars for more than 50 years. What would you ask NASA Mars scientists about the past, present, and future of exploration?
Join us on Wednesday, Aug. 5, from 11:00am-12:30pm PT for a @Reddit AMA:

What’s up for August?
A solar eclipse, one of the year's best meteor showers, Venus at its brightest, and a lunar eclipse!
Now through the end of the month, Saturn’s rings are on view – but you might notice something a little bit odd about them through your telescope. 🪐
The rings look thinner than normal because of the way that Saturn is tilted in relation to the Earth.

@voyagertech_’s Griffin-1 lunar lander is hot to go... through environmental testing.
The lander has arrived at @NASAJPL, where it will undergo testing to help verify it can withstand launch, landing, and the harsh conditions of space before its commercial mission supporting development of @NASAMoonBase.
