RT @NASA_LSP: 🚀Happy Launch-iversary SWOT!

#OTD in 2022, the Surface Water and Ocean Topography spacecraft became LSP’s 101st primary mission when it lifted off from Vandenberg Space Force Base on a SpaceX Falcon 9 rocket.

Did you know that SWOT recently collected data on a tsunami in Greenland that generated a seismic rumble which reverberated around the world for nine days!

RT @NASAhistory: Here's to 25 Terra-ific years! 🥂

#OTD in 1999, Terra, the flagship satellite of the @NASAEarth Observing System, was launched into space. It has been continuously collecting data ever since to help us understand how Earth is changing over time.

Happy launchiversary Terra!! https://t.co/wtIb4NISGh

#OTD in 2004, a massive 9.1 magnitude #Earthquake struck off the coast of northern Sumatra, #Indonesia. The event unleashed a devastating #Tsunami, caused widespread destruction, and became one of the deadliest disasters in modern history.

#OTD in 1975, @NASA announced that the Earth Resources Technology Satellite (ERTS) program had been renamed #LANDSAT. ERTS-1 was renamed Landsat 1. ERTS-B, the second satellite in the program, would be called Landsat 2 upon launch just eight days later, on January 22, 1975. https://t.co/weuiS6gzdr

Happy launch anniversary to Jason-3! 🚀
The ocean altimetry satellite was launched #OTD in 2016. Jason-3 carries a radar altimeter to monitor global sea level, wind speed at the ocean surface and significant wave height from 1,336 km above Earth 🛰️🌊: https://t.co/0GSTLcKc9A https://t.co/qYr8s2f0Js

#OTD in 2013, #Landsat 8—originally known as the Landsat Data Continuity Mission—was launched into space from #Vandenberg Space Force Base. Since then, it has made over 63,000 orbits and added more than 3 million Level-1 products to the archive. More here: https://t.co/Ibtd8iTBu1 https://t.co/1ZRf9R78jy

Alaska’s Glacier Bay was established as a national monument #OTD in 1925 and later designated as a national park and preserve in 1980. 🏔️

Scientists rely on #Landsat data to track glacial retreat, assess changes in vegetation, and monitor ecosystems.

#OTD in 1984, #Landsat 5 was launched into space. Far exceeding its three-year design life, Landsat 5 set a #GuinnessWorldRecord for the “Longest-operating #EarthObservation satellite.” Its longevity ensured a continuous stream of data that kept the Landsat archive intact. 🛰️🌎⭐ https://t.co/Ewjy82lguJ

Launched #OTD in 1984, #Landsat 5 transformed how we study our planet. 🛰🌍

Operating for 28 years and 10 months, it holds a Guinness World Record as the longest-operating Earth observation satellite.

What’s your favorite Landsat 5 image? 🤔

RT @NASAhistory: The lunar rover is put through its paces

Astronaut John Young took the Apollo 16 rover on a "Grand Prix" across the uneven dusty lunar surface #OTD in 1972. It was a planned experiment to test the performance of the lunar rover at "high" speeds—about 6 mph (10 km/h). https://t.co/J6GwAjN8I4
