![]() ![]() Will NASA Ignore it or embrace it? Its presence will be globally ubiquitous with versions simultaneously released in 160 languages (the Voyager interstellar message record only had 55). The sequel, “Avatar: The Way Of Water” will descend upon our world in December. In the 13 years since its release real science has shown the sheer immensity of possible planets in the universe – and how many of them could be habitable. These days you hear people at NASA – starting with the Administrator – talking about Astrobiology – searching for life elsewhere. The image was taken in a clean room at NASAs Jet Propulsion Laboratory in Southern California on January 15, 2020. Swatch nasa series#Inspired by NASA and its iconic spacesuits is the new Space Collection, a series of five watches, three of which feature elements of their bio-sourced material - two-thirds ceramic and one-third bio-sourced plastic. The swatch of material from the Wright brothers first airplane was obtained from the Carillon Historical Park, in Dayton, Ohio home to the Wright Brothers National Museum. Avatar portrayed the wonders of an alien biosphere on an extrasolar planet orbiting tha star in the system closest to Earth. This month, Swatch has taken the material and line to the next level. Cartographic accuracy of 12 m or better (including compensation for terrain effects) is required of Landsat 8 data products.Keith’s note: When “Avatar” first came out in 2009 NASA almost completely ignored it (see “ Avatar: A Stunning New World That NASA Continues to Ignore” from 2010 ). The nominal spacecraft altitude is 705 km. The Landsat 8 scene size is 185-km-cross-track-by-180-km-along-track. ![]() This increases the probability of capturing cloud-free scenes for the global landmass. Landsat 8 has been regularly acquiring 725 scenes per day (and Landsat 7 is acquiring 438 scenes per day). Swatch nasa archive#Landsat 8 is required to return 400 scenes per day to the USGS data archive (150 more than Landsat 7 is required to capture). The 100 m TIRS data is registered to the OLI data to create radiometrically, geometrically, and terrain-corrected 12-bit data products. TIRS collects data for two more narrow spectral bands in the thermal region formerly covered by one wide spectral band on Landsats 4–7. Note: atmospheric transmission values for this graphic were calculated using MODTRAN for a summertime mid-latitude hazy atmosphere (circa 5 km visibility).Graphic created by L.Rocchio & J.Barsi. The Thermal Instrument (TIRS) carries two additional thermal infrared bands. Additionally, the bandwidth has been refined for six of the heritage bands. The OLI collects data for two new bands, a coastal/aerosol band (band 1) and a cirrus band (band 9), as well as the heritage Landsat multispectral bands. OLI provides two new spectral bands, one tailored especially for detecting cirrus clouds and the other for coastal zone observations. The graphic below compares the OLI spectral bands to Landsat 7′s ETM+ bands. OLI collects data for visible, near infrared, and short wave infrared spectral bands as well as a panchromatic band. OLI is a push-broom sensor with a four-mirror telescope and 12-bit quantization. ![]() OLI improves on past Landsat sensors using a technical approach demonstrated by a sensor flown on NASA’s experimental EO-1 satellite. Landsat 8 instruments represent an evolutionary advance in technology. ERTS - 1, orbiting 14 times a day, scans a swatch 185 km ( 115 miles ) wide in four bands of the spectrum to produce images that reveal much about Earth's. USGS leads post-launch calibration activities, satellite operations, data product generation, and data archiving at the Earth Resources Observation and Science (EROS) center. On May 30, 2013, USGS took over routine operations and the satellite became Landsat 8. NASA led the design, construction, launch, and on-orbit calibration phases, during which time the satellite was called the Landsat Data Continuity Mission (LDCM). Landsat 8 was developed as a collaboration between NASA and the U.S. These two sensors provide seasonal coverage of the global landmass at a spatial resolution of 30 meters (visible, NIR, SWIR) 100 meters (thermal) and 15 meters (panchromatic). ( The Landsat 8 Launch in Quotes.) The Landsat 8 satellite payload consists of two science instruments-the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). Landsat 8 launched on February 11, 2013, from Vandenberg Air Force Base, California, on an Atlas-V 401 rocket, with the extended payload fairing (EPF) from United Launch Alliance, LLC. ![]()
