Designed to complete only 16,000 orbits, Landsat 5 continued to deliver images of our ever-changing planet daily well past the expected lifespan. Today, Landsat 8 & 9 continue to orbit and image Earth.

[NOAA Satellites @NOAASatellites]

It's #WhereInTheWorld Wednesday!

We’re still giddy after yesterday's launch of @NOAA's geostationary satellite, #GOEST, so we’re featuring a special spot here in Florida. Seen by #GOESEast, this wildlife refuge is home to nearly 2,000 different species—and to @NASAKennedy.

Launched in December 2021 on an Ariane 5 rocket, #Webb is designed and built to offer scientists the capabilities needed to push the frontiers of knowledge in many areas of astronomy. Learn about #Webb from our 📖 #HubbleWordBank: https://t.co/XGg2Nozaal

Many engineers participate in every step of a #Landsat's lifespan: from creation to ground systems to calibration to data access. Without them, the program would not be possible. Enjoy the final day of #EngineersWeek!

Just putting this out there. @Buccaneers, I’ve never officially retired and did well the last time I stepped in for @TomBrady. 🤷‍♂️

A tale of two moons - tiny Epimetheus and cloudy Titan, as seen from Cassini.

Here are Saturn's rings in a new light.

NASA's @CassiniSaturn spacecraft took this image of Saturn's C and B rings (from left to right) on June 30, 2004, using an Ultraviolet Imaging Spectrograph.

Good morning San Francisco! Looking forward to #photonicswest for the first time in two years.

[Materion Corporation @MaterionCorp]

Materion's high-reliability #hermetic lids protect #photonic devices for smart glasses, LIDAR, autonomous vehicles, MEMS devices, and more. Your source for #microelectronic packaging, visit our team at #PhotonicsWest booth #1359 next week to find your custom solution!

Every winter The Black Hills community hosts the Burning Beetle celebration, bringing awareness to a local infestation. Pine beetles are about the size of a grain of rice, too small to view in Landsat images. What is visible is what the beetles can do to a pine forest. 🛰️🪲

In 2007, #Landsat 7 brought the coldest continent to life with high resolution satellite imagery. An international collaboration, Landsat Image Mosaic of Antarctica (LIMA) increases access to this southernmost environment.

Secondary mirror deployed! ☑

[HUBBLE @HUBBLE_space]

. @ESA_Webb follows Hubble in the line of great space observatories. The #BFFinSpace 🤜🤛 series will look at Hubble & Webb, how they compare, differ and complement each other.

Next Year, the Landsat program is celebrating 50 years of satellite observation, holding images from each of the seven orbiting satellites. With Landsat 9, we add not only another satellite but also to the legacy the program has created.

Congratulations @NASA on the launch of the Webb Space Telescope! We’re proud to have played a part in this new chapter in space exploration and can't wait to see what happens next. See the steps to get the telescope fully deployed: https://t.co/ksr52cZy96 #UnfoldTheUniverse

Speed is an important consideration in engineering design because kinetic energy can impact the failure process of materials. Learn how speed affects the interaction between materials and environmental forces in our latest “In Our Element” blog post: https://t.co/xiVJ6fWZAF

[USGS Landsat @USGSLandsat]

On the Ninth Day of Landsat the USGS gave to me: a newly launched Landsat-9! Landsat-9 has up-to-date sensors to provide top-notch science, made available in early 2022 via EarthExplorer.
