Rest in Peace Jim Lovell. 😢
I remember an exciting talk he gave about his Apollo 13 experience at Georgia Tech, which was truly inspirational.

Today, it has been 6 months since Europa Clipper launched from Kennedy Space Center, shortly after hurricane Milton caused havoc in the region.
The spacecraft has been doing great ever since!

Today we are five years away from Europa Clipper’s arrival at Jupiter on April 11, 2030.
Are you ready for exciting discoveries about Europa, an icy moon that might harbor life in its subsurface ocean? 🤩

Now that the Mars flyby of Europa Clipper was successful, the team is starting the preparations for a “cleanup maneuver” scheduled later this month, which will put the spacecraft in a good trajectory to fly by the Earth next year!

Four years ago, our fierce #Perseverance rover landed on Mars. In the midst of an unprecedented pandemic, we were all reminded - even if temporarily - of what can be accomplished when we all work together. Here’s to many more years of exploration and discovery on the Red Planet. Merci! 🤩🎂

I don’t know who took this shocking picture, but it shows how close the fire got to JPL. 😱

Things are very scary here in Pasadena. And the winds are only gonna get worse.
I’m using the app Watch Duty to check the fire map and get evacuation orders info. Stay safe everyone.

Before the “skycrane”, Martian rovers from JPL used airbags to stop the vehicle upon touchdown. Pathfinder was the first mission to use this technique, tested here in New-Mexico in 1993.
