NASA and the Indian Space Research Organisation (ISRO) have joint hands to build an Earth observation satellite called NISAR (NASA-ISRO Synthetic Aperture Radar (SAR) Mission). The space artifact will be in charge of measuring changes in the Earth’s surface related to motions of the crust and ice surface, and its launch is scheduled for 2021.

Its mission will comprise snow and glacier studies in the Himalayas, monitoring of agricultural biomass over India, Indian coastal and near-shore ocean studies, and disaster monitoring and management.

NASA’s Earth observation Aqua satellite spotted the wildfires burning throughout California, Oregon, Washington, Idaho and Montana states on August 23. One of the most important blazes was reported in the Okanogan Complex, in Washington State. It has burned 287,704 acres (116,000 hectares) and killed three firefighters. More than 1,774 fire personnel from 33 states are currently fighting it or working to support the firefighting effort.

NASA’s Goddard Space Flight Center has released a high-resolution video that simulates Hurricane Katrina’s movement across the Atlantic Ocean, then the Gulf of Mexico, and its final collision with the southern part of the United States. It combines observational data with a high-resolution model of Earth, called GEOS-5, and reflects scientists’ better understanding of heavy storms.

Stunning images of the Atsani typhoon have been captured by CloudSat and Aqua satellites on August 19. The first space artifact passed near its eye and collected information about the inside of the typhoon through its cloud-penetrating radar. For its part, the MODIS web on the Aqua satellite passed above Atsani capturing an image of the storm's eyewall where the the red line is the north-to-south track that CloudSat took.

NASA has began to build its new satellite mission focused on predicting hurricanes, called Cyclone Global Navigation Satellite System (CYGNSS), with the collaboration of the University of Michigan. It will comprise eight Earth observation (EO) microsatellites which will be able to measure ocean surface winds associated with tropical cyclones, typhoons and hurricanes throughout their life cycle. Their launch is expected in late 2016 from Cape Canaveral in Florida.

Scientists at NASA’s Jet Propulsion Laboratory have found that the ocean levels in Central and Eastern Pacific have increased between March and July 2015, which bears a resemblance to the conditions of the potent El Niño event of 1997-98. The research was carried out through altimetry measurements captured by the OSTM/Jason-2 satellite.

NASA has funded a new satellite-based fire detection tool in operation now at the U.S. Department of Agriculture (USDA) Forest Service (USFS).

The new tool uses high-resolution data from the Suomi National Polar-orbiting Partnership (NPP) satellite with a cutting-edge computer model to predict how a fire will change direction based on weather and land conditions. It will allow detecting smaller fires with precise detail and will help firefighters developing their tasks.

Ball Aerospace & Technologies Corp. is teaming up with NASA in the development of the Joint Polar Satellite System (JPSS-1), USA’s next environmental spacecraft, which will presumably be launched in 2017.

This polar-orbiting artifact’s mission will consist of collecting science-quality atmospheric, oceanographic, and land surface measurements that are crucial for the country's weather mission. It will work in conjunction with the Suomi National Polar-Orbiting Partnership Satellite (Suomi-NPP), another environmental spacecraft launched in 2011 and also built by Ball.

The Aquarius/Satélite de Aplicaciones Científicas (SAC)-D satellite observatory, a joint project between NASA and Argentina’s Space Agency (CONAE), with participation from Brazil, Canada, France and Italy, has ended its activity after nearly four years.

The international Earth-observing mission, launched in 2011 to study the salinity of the ocean surface, has been brought to an end due to the shut down of an essential part of the power and attitude control system for the SAC-D spacecraft.
