Landsat 9 was successfully launched on Monday, Sept. 27, 2021 from Vandenberg Space Force Base in California. Landsat 9 data is publicly available from USGS.

Landsat 9—a partnership between NASA and the U.S. Geological Survey— continues the Landsat program’s critical role in monitoring, understanding and managing the land resources needed to sustain human life.

Today’s increased rates of global land cover and land use change have profound consequences for weather and climate change, ecosystem function and services, carbon cycling and sequestration, resource management, the national and global economy, human health, and society.

Landsat is the only U.S. satellite system designed and operated to repeatedly observe the global land surface at a moderate scale that shows both natural and human-induced change.

Since reducing the risk of a Landsat data gap is a high priority of the U.S. Sustainable Land Imaging Program, Landsat 9 has a design very similar...

Amazônia-1 is the first Earth Observation satellite completely designed, integrated, tested and operated by Brazil. It features the optical Advanced Wide Field Imager (AWFI), with swath width 850 km and 60 m resolution, capturing images in 3 visible bands and 1 near-infrared (NIR) band. It has a high revisit period of 5 days, which is important for increasing the probability of capturing useful images over frequently overcast areas including the Amazon region. The data will be accessible to the scientific community, government agencies, and to users interested in a better understanding of the terrestrial environment. The Amazon mission is planned to have three remote sensing satellites: Amazonia-1, followed by Amazonia-1B and Amazonia-2.

The Argentinean Microwaves Observation Satellite 1B (SAOCOM 1B) was launched into orbit on August 30, 2020 from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida, United States of America. Developed by the National Argentinean Space Commission (CONAE) in corporation with the Italian Space Agency (ASI), this new satellite joined SAOCOM 1A and four Italian COSMO-SkyMed to complete the Italian-Argentinean Satellite System for Emergency Management (SIASGE). The SAOCOM 1B satellite orbits at 620 km above the earth's surface and is fitted with a Synthetic Aperture Radar (SAR) sensor that makes use of microwaves in the electromagnetic L-band. The spatial resolution of its imagery ranges between 10 and 100 meters. The data collected by SAOCOM 1B helps monitor climatological disasters (forest fires, glacial lake outbursts, droughts) and hydrological disasters (landslides and floods).

Cartosat-3 satellite is a third generation agile advanced satellite having high resolution imaging capability. Cartosat-3 will address the increased user’s demands for large scale urban planning, rural resource and infrastructure development, coastal land use and land cover etc.

MetOp-C is the third and last satellite of the MetOp series that forms the space segment of the EUMETSAT Polar System (EPS).
MetOp (Meteorological Operational) is Europe's first polar-orbiting operational meteorological satellite. It is the European contribution to the Initial Joint Polar System (IJPS), a co-operative agreement between Eumetsat and the US National Oceanic and Atmospheric Administration (NOAA) to provide data for climate and environmental monitoring and improved weather forecasting.
MetOp-A (launched on 19 October 2006), MetOp-B (launched on 17 September 2012) and MetOp-C (launched 7 November 2018) are in a lower polar orbit, at an altitude of 817 kilometres, to provide more detailed observations of the global atmosphere, oceans and continents. The three satellites will operate in unison for as long as Metop-A's available capacities bring benefits to users. NOAA still continues to operate its mid-afternoon orbit satellite service as part of the...

NovaSAR-1 was launched into orbit on September 16, 2018 from Satish Dhawan Space Centre in Sriharikota, India. It was developed by the United Kingdom Space Agency (UKSA) in cooperation with the Indian Space Research Organisation (ISRO), the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Department of Science and Technology-Advanced Science and Technology Institute (DOST-ASTI) of the Republic of the Philipines. NovaSAR-1 orbits at 583 km above the earth's surface and is fitted with a Synthetic Aperture Radar (SAR) sensor that makes use of microwaves in the electromagnetic S-band. The spatial resolution of its imagery ranges between 6 and 30 metres. The data collected by NovaSAR-1 helps monitor climatological disasters (forest fires and droughts) and hydrological disasters (floods).

The ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) mission measures the temperature of plants to better understand how much water plants need and how they respond to stress. ECOSTRESS is attached to the International Space Station (ISS) and collects data over the conterminous United States (CONUS) as well as key biomes and agricultural zones around the world and selected FLUXNET (http://fluxnet.fluxdata.org/about/) validation sites. A map of the acquisition coverage can be found on the ECOSTRESS website (https://ecostress.jpl.nasa.gov/science).

Carrying a suite of cutting-edge instruments, Sentinel-3 will measure systematically Earth’s oceans, land, ice and atmosphere to monitor and understand large-scale global dynamics. It will provide essential information in near-real time for ocean and weather forecasting.
The mission is based on two identical satellites orbiting in constellation for optimum global coverage and data delivery. For example, with a swath width of 1270 km, the ocean and land colour instrument will provide global coverage every two days. Sentinel-3B was launched on 25 April 2018.
With a focus towards our oceans, Sentinel-3 measures the temperature, colour and height of the sea surface as well as the thickness of sea ice. These measurements will be used, for example, to monitor changes in sea level, marine pollution and biological productivity.
Over land, this innovative mission will provide a bigger picture by monitoring wildfires, mapping the way land is used, provide indices of...
