Billions of years ago, a river coursed through the area where @NASAPersevere is now. The rocks it brought in hold stories not only of where they came from, but how they got there. What could they reveal about possible ancient life on Mars? Read more: go.nasa.gov/3K5IXJA

A large wildfire broke out on La Palma, the most northwesterly of the Canary Islands.

Fires here are common in the summer due to the island’s dry climate. @nasa's Aqua satellite captured the stream of smoke on July 15. go.nasa.gov/46S2hEb

What's going on with the hole in the ozone layer?

Thanks to a global effort to regulate ozone-depleting substances, the ozone hole is showing signs of recovery and is projected to return to a healthy level by mid-century. nasa.gov/esnt/2022/ozone-hole-…

Nice.

Just on time for humans to finally cop on to the fact that we have killed ourselves with our carbon excesses.

in reply to NASA

We could have done that with CO2, if we had wanted to.


Today’s students are tomorrow’s rocket scientists!

One of our #Artemis Student Challenges recently put undergraduate students’ skills to the test during the 14th First Nations Launch High-Power Rocket Competition.

Congratulations to all the competitors: go.nasa.gov/3XW3Z3f

Rock nerds rejoice! From big boulders to tiny pebbles, the ancient riverbed I’m exploring right now has it all. Washed in from upstream, these fragments can help my team uncover the river’s past and its potential for supporting ancient life. Read more: go.nasa.gov/3K5IXJA

Rogue planets – worlds that drift through space untethered to a star – may far outnumber planets that orbit stars. @NASARoman, set to launch in 2027, could help us find Earth-sized rogues, which would help us better understand planet formation. go.nasa.gov/43snphm

No, but... I did make sure the whole ciclops.org website didn't disappear from the Internet. So I got all... The photos.

50 years ago, Skylab's prime spider, Arabella, was preparing for launch. From over 3,400 proposals from high school students across the country, the "Web Formation" experiment was one of 25 chosen to fly on Skylab. #Skylab50

📸 Dr. Ray Gause feeds Arabella a fly in July 1973
#NASAhistory



Judith Miles, a high school student from Lexington, Mass. (shown here discussing her project), proposed the “Web Formation in Zero Gravity” experiment to determine how well spiders adapt to microgravity.

These students were the first ever to have experiments flown in space, but they weren't the last. Student experiments have been conducted on the @Space_Station over the last 20+ years.

📸 The 25 students whose Skylab experiments were chosen meet at @NASA_Marshall in May 1972

I proposed an experiment for one of the space shuttle missions that flew science “cans” when I was a kid. My idea didn’t make the cut, but I didn’t mind when I saw how amazing the winning projects were.

(Bonus pointless fact: I applied for the astronaut program when I was a grownup. I didn’t make the cut, but I didn’t mind when I saw how amazing the people who were selected turned out to be.)

10 years ago today the Cassini spacecraft peered past Saturn's rings and captured this image of a distant bluish planet and its moon. That's Earth, seen from over 900 million miles away! #SmileYoureOnCassiniCamera

Image description

The dark side of Saturn, its bright limb, the main rings, the F ring, and the G and E rings are clearly seen; the limb of Saturn and the F ring are overexposed. The "breaks" in the brightness of Saturn's limb are due to the shadows of the rings on the globe of Saturn, preventing sunlight from shining through the atmosphere in those regions. The E and G rings have been brightened for better visibility.

This one was too easy but thanks to all who played along. Chile is correct!!

Why does the exhaust plume look so...toxic? Is it the association of yellow-brown clouds with smog?

The future is full of questions for us earthly life-forms. How far can we take our search for life elsewhere? Which new technologies are best for detecting life? Could we ever visit planets beyond our solar system? @nasa is looking for answers.

Geo-quiz time! 🤔

Launched just before Y2K in Dec. 1999, NASA's Terra satellite has provided a continuous view of Earth over its 23 years of operation.

This is one of the very first images Terra took with its MODIS instrument on Feb. 24, 2000. What country's coastline is this?

#OTD in 1966, John Young and Michael Collins launched for the 3-day Gemini X mission. The astronauts rendezvoused with 2 Agena target vehicles, set a record altitude for humans in space, and performed a spacewalk from one spacecraft to another.
