Status update: I've reached the rim of Jezero Crater! The ascent took 3.5 months and included 1,640 feet (500 m) of vertical climb. It was steep and slippery — but I'm built to do hard things. Next up? My 5th science campaign, the Northern Rim. go.nasa.gov/49Bn4xr

Today, Bishop Mariann Edgar Budde boldly called out Donald Trump for his hatred and bigotry at the National Cathedral Prayer Service. Now, the GOP is attacking her for speaking truth to power. RETWEET if you stand with Bishop Budde against Trump!

If your Christianity causes you to be offended by someone asking the most powerful person in the country to be merciful towards the powerless, then you have deeply, deeply misunderstood the teachings of Jesus Christ.

Now that I've completed my climb out of Jezero Crater, I'm back to #SamplingMars! My 26th sample, known as "Silver Mountain," has textures unlike anything we've seen before. I've sealed the rock core in a sample tube so it can be analyzed in labs on Earth in the future.

I do not see how Trump can be allowed to come to the G7 in Canada in June. Never mind that we don't generally let convicted felons enter the country: how on earth do we "welcome" on our soil someone who is committed to wiping us off the map? I'm not sure there's much point in

The Planetary Society strongly opposes the sudden, indiscriminate dismissal of more than 1,000 scientists, engineers, and explorers at NASA — the largest involuntary workforce reduction since the end of the Apollo program. Read more on our stance. planetary.org/press-releases…

Today marks four years of exploring, discovering, and collecting Mars’ treasures for our NASA's Perseverance Mars Rover rover. We’re incredibly proud this mission and the amazing team behind the rover. I look forward to the day that the samples Perseverance is collecting reshape what we know

Elon Musk attacked democracy defender and superstar court lawyer Marc Elias as “undermining civilization,” taunting him by asking if he suffered “generational trauma.” Elias’s response was brilliant and worth amplifying: Mr. Musk, You recently criticized me and another prominent

And would effectively remove the ability for American citizens living outside the US from voting. It would violate the inalienable right of every American citizen to vote no matter where they live.

I came to Mars to search for ancient microscopic life – but I’m also helping future explorers! These spacesuit material swatches have been exposed to the harsh Martian environment for the past four years to help inform the design of future suits. go.nasa.gov/4hOIMke
