The Pale Blue Dot is one of the most striking images ever taken of our planet. In 1990, the Voyager 1, already far beyond the outer planets, turned its camera back toward home from about 6 billion kilometers away. Earth appeared not as a world, but as a tiny, almost invisible speck of light.

For Carl Sagan, that speck carried enormous meaning:

“That dot is us. Every person who has ever lived—every story, every triumph, every conflict—unfolded on that single, fragile point. All of human history exists there, suspended in a beam of sunlight.

It’s a humbling perspective. Earth is, for now, the only place we know that can support life. There’s no easy escape, no second home waiting for us. That distant image reminds us how small we are—and how important it is to take care of each other, and the only world we share.”

A Pink Moon in full bloom 🌸

The Moon will appear full this weekend, with its peak on Saturday evening. April's "Pink Moon" is named after the herb moss pink, one of the earliest widespread flowers of spring.

Sunrise, sunset
Swiftly flows the lunar day

Thanks to cameras aboard @fireflyspace's Blue Ghost lander, we've seen the start and end of a day on the Moon. Check out the science we did in between: https://t.co/LhyisPv9Qx

As a reminder, our mission is to accelerate the world’s transition to sustainable energy

Cleaner, more livable cities & a fully renewable economy that benefits all on Earth 💚

#BlueGhost got her first diamond ring! Captured at our landing site in the Moon’s Mare Crisium around 3:30 am CDT, the photo shows the sun about to emerge from totality behind Earth. Hope to have more shots to share soon! #BGM1

Blue Ghost turns red! Our lander downlinked more imagery from the Moon captured around 2:30 am CDT during the totality of the solar eclipse last night. These images - rapidly captured by our top deck camera with different exposure settings - were stitched together in a quick clip. The red hue is the result of sunlight refracting through the Earth's atmosphere as the sun is blocked by our planet, casting a shadow on the lunar surface. The glowing ring of the eclipse is again seen on Blue Ghost’s solar panel. #BGM1

[NASA @NASA]

We've looked at an eclipse from both sides now...
While @NASAGlenn was looking up to see last night's Blood Moon, @fireflyspace's Blue Ghost lunar lander was looking back at the "diamond ring" of a solar eclipse. A reminder that what you see often depends on your point of view.

Our lunar delivery initiative is high risk–with the potential for high reward.

Shortly after landing in a crater near the lunar South Pole, @Int_Machines’ Athena lander collected data and called an early end of mission at 1:15am ET (0615 UTC) March 7. https://t.co/32Vm7LewF1
