The Advanced Land Observing Satellite-4 (ALOS-4) is a satellite to observe the Earth's surface using its onboard phased array type L-band synthetic aperture radar (PALSAR-3). The L-band radar technology has continuously been developed in Japan. With further improved observation performance compared to the predecessor PALSAR-2 aboard the DAICHI-2 (ALOS-2), JAXA and its prime contractor, Mitsubishi Electric Corporation, are developing the satellite aiming at achieving both high resolution and a broader observation swath.
Unlike observations by an optical sensor, radar images can be acquired day and night as it does not require sunlight. Moreover, since radio waves can penetrate cloud, the images can be obtained regardless of weather condition. The ALOS-4 will leverage these merits for observing and monitoring disaster-hit areas, forests, and sea ice. In addition, it will also challenge new areas such as monitoring infrastructure displacement.
The ALOS-4 will be equipped...

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.

PRISMA (Hyperspectral Precursor of the Application Mission), mission fully funded by Italian Space Agency (ASI), is an Earth Observation system with innovative, electro-optical instrumentation that combine a hyperspectral sensor with a medium-resolution panchromatic camera. The advantages of this combination are that in addition to the usual capability of observation based on recognising the geometric characteristics of the scene there are hyperspectral sensors which determine the chemical-physical composition of the objects present on the scene. This offers the scientific community and users many applications in the field of environmental monitoring, resource management, crop classification, pollution control and other things.

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).
