With one of its twin satellites almost out of fuel after more than 15 years of chasing each other around our planet to measure Earth's ever-changing gravity field, the operations team for the U.S./German Gravity Recovery and Climate Experiment (GRACE) mission is making plans for an anticipated final science collection.

With lift-off set for 13 October, engineers at Russia's Plesetsk launch site are steaming ahead with the task of getting Europe's next Copernicus satellite ready for its journey into orbit.

Today, EUMETSAT and Arianespace announced the signature of a contract entrusting Arianespace with the launch of the first two Metop-SG satellites of the EUMETSAT Polar System of Second Generation plus an option for the launch of a third satellite.

NASA-NOAA's Suomi NPP satellite captured night-time look at Hurricane Irma as it weakened to a large tropical storm and the GOES East satellite provided a daytime view as the large storm continued moving north over Florida.

The Sentinel-5P satellite has arrived in Plesetsk in northern Russia to be prepared for liftoff on 13 October. Built to deliver global maps of air pollutants every day and in more detail than ever before, this latest Copernicus mission will set a new standard for monitoring air quality.

The launch of JPSS-1, the first in a series of NOAA's four next-generation operational polar-orbiting weather satellites that will give scientists the most advanced tools to aid in weather forecasting and earth observations, is scheduled for 10 November at 1:47 a.m. PST from Vandenberg Air Force Base in California.

High resolution optical imaging Earth Observation Satellite (EOS) systems such as CARTOSAT provide multi-spectral remote sensing data in the visible and near-infrared (VNIR) wavelengths of the order of sub-meter to few-meters.

Flying with an exceptionally lightweight payload, a Falcon 9 rocket delivered a multipurpose research satellite into a nearly 450-mile-high orbit on 24 August for Taiwan following a smooth countdown and liftoff from California's Central Coast.

Lasers that will fly on NASA's Ice, Cloud and land Elevation Satellite-2, or ICESat-2, are about to be put to the test at the agency's Goddard Space Flight Center in Greenbelt, Maryland.

The TOPEX-Posiedon satellite ascended into orbit in 1992, and ushered a new era of oceanography with the first highly accurate, global measurements of sea levels.

A feat 19 years in the making, NOAA-15 recently made its 100,000th trip around the Earth!

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

An ozone-measuring instrument that launched to the International Space Station in February has completed commissioning and is now collecting atmospheric data.

A magnitude 6.6 earthquake occurred in the Aegean Sea on 20 July 2017, affecting the Greek island of Kos and Bodrum in south-west Turkey. Images from the Copernicus Sentinel-1 mission were used to map the ground deformation, providing valuable data for analysis.

A new instrument that will monitor our planet's biggest power source, the Sun, arrived at NASA's Kennedy Space Center in Florida. It has a targeted November 2017 launch on a SpaceX Falcon 9 rocket to the International Space Station.

Progress continues on the development of NOAA's GOES-S and GOES-T spacecraft that will follow the successful launch of GOES-R, renamed GOES-16 upon reaching geostationary orbit.

Launched on the morning of 23 June from India, the Aalto-1 satellite's first month in space has gone according to plan.

The European Union's Copernicus Sentinel-1 mission is providing far more images than previous generations of synthetic aperture radar satellites, bringing many significant advantages. One of them is determining the difference between naturally-occurring and polluting oil on the ocean surface.

With Sentinel-5 Precursor about to be packed up and shipped to Russia for lift-off in late September, media representatives, members of the UK Space Agency and National Centre for Earth Observation had the chance to see this Copernicus air-pollution monitoring satellite standing proud in the cleanroom.

A Russian Soyuz booster lifted off Friday from Kazakhstan on a complex mission to deploy 73 satellites into three different orbits, including a Russian spacecraft to locate forest fires, 48 CubeSats for Planet's global Earth observation fleet, and eight nanosatellites for Spire Global's commercial weather network.
