#Repost by @nasa ・・・ Summer is in full bloom 🌀☀️ Phytoplankton thrive in the summer season! The plumes of turquoise, green, and light blue hues in these waters are made up of tiny, microscopic plant-like organisms that live in these areas year-round. During late spring through to late summer, the specific combination of water temperature, nutrients, and sunlight cause populations of these plant-like organisms explode into enormous blooms, which can be seen here by our @NASAEarth Landsat 8 satellite. The swirls and shapes of the phytoplankton blooms are stimulated by the oceans’ complex circulation and abundant fronts – where separate water masses with distinct temperatures, salt levels and nutrients meet. 📸 Baltic Sea 📸 Gulf of St. Lawrence 📸 Labrador Sea Credit: NASA/Joshua Stevens/Lauren Dauphin #NASA #NASAEarth #Phytoplankton #landsat8 https://www.instagram.com/p/CRsPHx_Al-IhPRGxcPzQo2s8F3Gh0Bj4EsL5bQ0/?utm_medium=tumblr

So here are two images which I really liked of the Landsat8′s work: First: The west part of the Nile river is so dry—receiving just centimeters of rainfall per year—that researchers describe it as “hyper-arid.” Greenery, however, has been cropping up in the area in recent decades. On February 26, 2017, were these natural-color images of Egypt’s land reclamation project captured. Second: Taken on August 10th, 2013 by the Landsat-8 satellite, this image shows the active fire areas along with burn scars during the Idaho Wildfires.

While imaging the Turkish highlands September 7, the Landsat 7 Earth observation satellite spotted something else - the International Space Station! Although the two spacecraft orbit more than 200 miles apart - the ISS 250 miles above Earth and Landsat 7 at 440 miles - orbital mechanics causes the laboratory to underfly the satellite a few times a year. Multiple Landsat satellites have captured various space objects over their operational lifespans, including the space shuttle, spent rocket stages, and other satellites. In fact, this exact phenomena occurred earlier this year, when the Landsat 8 satellite spotted the station flying in its line of sight.

Landsat 8: Monitoring the Earth's Surface

Landsat 8, also known as the Landsat Data Continuity Mission, is a NASA satellite mission that provides detailed imagery of the earth. The Landsat satellites continuously record the entire land surface of the earth from space. The data from these satellites is used to track changes on the earth’s surface and is used by scientists and people who work in agriculture, education, business, science and government agencies.

Why Landsat 8 Is Important Every day, Landsat 8 provides more than 400 detailed images that scientists, private industry, and resource managers use to monitor changes and make informed decisions. Landsat 8 is used to make decisions that affect everyone on our plant to include: 

Providing detailed images of changes to the earth due to natural disasters such as fire, landslides, and floods. 

Helping farmers analyze the health of their crops & identifying potential diseases. 

Assisting water managers to make decisions by identifying possible pollution, as well as locating clean water for refugees in arid countries.

  How General Dynamics C4S Supports Landsat 8 The General Dynamics C4S team provides the systems engineering and integration services for the ground-based command and control system for the Mission Operations Element (MOE). The team had to ensure that the Landsat 8 ground system and ground communications were tested, verified, and validated. The GDC4S team combined a number of computers and highly specific software to ensure that the Mission Operations Center team could talk to the spacecraft and fluently communicate information needed to keep Landsat 8 operating smoothly after launch. For their outstanding work on the Landsat 8 ground systems, the General Dynamics C4S team received a prestigious Goddard Award for Engineering in 2013 (Team members pictured below). 

Fun Fact about Landsat 8 - The satellite travels over 4 miles every second and only takes 16 days to take images of the over 57 million square miles of land on earth. Great video from NASA on Landsat 8: http://www.youtube.com/watch?v=uvDuBG9KlQU

NASA launches Landsat 8 satellite to better study the skies above, water below - published on: Technology Companies List

NASA’s Landsat program recently turned the big four-oh, and what better way to deal with the mid-life crisis by getting a new satellite as a present? Accordingly, the space agency has just launched Landsat 8 into orbit to give its Earth Science program a new injection of youth. The new vehicle improves the accuracy of existing light and thermal sensors while widening the scope to better reflect modern climate studies — number 8 now tracks aerosols in the atmosphere, high cirrus clouds and the telltale signs of water quality and consumption levels. We won’t get the first USGS-derived results …
