Five down, five to go, as I lay down my backup set of 10 samples.

In this tube: a core sample from a rock that formed from magma, then was altered by water several times. It could help scientists understand the early history of this area, when life may have been present. 🔎🪨

Why put them down? The wind could bury them in sand by the time you go to pick them up. Wouldn’t they be easier to find if they’re in/on the rover?
Doesn’t Percy have a trunk?


Meanwhile, here’s more on what my team learned from early studies of this rock and others like it: go.nasa.gov/3s848ml

An atmospheric river drenched California on Jan. 4 and 5, 2023. 🌧️

A plume of moisture from the tropical Pacific interacted with a low-pressure system that rapidly strengthened over the northeast Pacific, producing an intense storm.

The map above shows how much potential liquid water is in the atmosphere on Jan. 4, 2023. The dark green swoop on the map indicates moisture flowing from the tropical Pacific toward California.

As of today, I’ve ridden the Red Planet around our Sun one whole time. Highlights from my first Mars year:

✅Explore vast crater floor
✅Collect 18 samples
✅Examine ancient river delta
✅Start laying down samples for #MarsSampleReturn

Many adventures still ahead, so...onward!

Percy, did you lose some spare part in the 3rd picture?


25 years ago today, NASA's Lunar Prospector spacecraft was successfully launched, and went on to orbit the Moon for almost 19 months to map its surface composition and to look for polar ice. This image from Lunar Prospector data shows thorium concentrations on the Moon's surface.

What methods were used to map composition? Are there maps for all the other elements?


Lunar Prospector was one of the missions of NASA’s Discovery Program, a series of lower cost, competed missions to explore the solar system.

I've always thought of a science fiction story where Venus developed intelligent life before us, but they polluted their atmosphere so much that they turned into the toxic hellhole that Venus is. Imagine someday a probe landing there and finding the ruins of civilization. 😳

Hello I have questions like if that star cluster was contained in a sphere, what's its radius? How many stars are there? What is the average distance between stars? What happens to star clusters over time?

I'll take me answers off the air, thanks.

We talk habitable zones a lot. It's the distance from a star where orbiting planets *could* have surface water, but it doesn't guarantee they do. It is a very handy way to target planets for further observations! exoplanets.nasa.gov/search-for…

Heads up! @NOAASatellites' GOES-18, launched in March 2022, is now #GOESWest. Miles above Earth, it’ll observe the Western Hemisphere, helping weather forecasters, emergency managers, and all who want to know more about our changing planet.

Take a look: go.nasa.gov/3Ggz2OS
#NASA

in reply to NASA

This is awesome, of course. But, how does a satellite observe *only* one hemisphere? Whether North, East, South, or West, does not a satellite always observe them all, even if partially? Edit: OK, I acknowledge that a geostationary orbit will observe only one hemisphere, and if placed in a perfectly positioned location, will only ever observe one hemisphere. At 90°W, there we have it. Mea culpa

can the distance from their sun be estimated? One solar orbit in 6 days seems would place a huge gravitational strain on the planet.

Heavy rain on New Year’s Eve 2022 flooded California near San Francisco and Sacramento.

Flooding is visible in the false-color satellite image from Jan. 1, 2023 (right), with water in blue, compared to the image from Dec. 16, 2022 (left).

Looks like Sacramento and Stockton are more vulnerable to storm surges and flooding than coastal areas on these maps.
in reply to NASA

We’re not close now, but shades of the 1861 Central Valley floods that inundated Sacramento and Stockton and pretty much everything else.


Our space science can also benefit life on Earth, contributing to better understanding of diseases like Alzheimer's, improved agricultural techniques & advanced tech developed via quantum science. That's just the beginning.
