Earth Observation Mission News
The world's first space-based system to help identify specific sources of greenhouse gas emissions is now circling the Earth.

On 17 February 2018, the Sentinel-2 mission reached the 5-day global revisit periodicity, thus fully exploiting the two satellite units of the constellation.

Originally designed as a two-year mission and launched on 22 October 2001, Proba-1 is still going strong, providing very valuable hyper-spectral data.

For the last several years, scientists at NASA's Langley Research Center in Hampton, Virginia, have been exploring the secrets of clouds to improve weather predictions — everything from daily forecasts to keeping aircraft clear of dangerous conditions.

NOAA's GOES-S, the second in a new series of four highly advanced geostationary weather satellites, blasted into orbit 01 March at 5:02 p.m. EST from Cape Canaveral, Florida. GOES-S mission managers confirmed that its solar arrays successfully deployed at 8:58 p.m. EST and the spacecraft was operating on its own power.

ICESat-2, or the Ice, Cloud and land Elevation Satellite-2, is slated to launch in September to measure the height of Earth's surface, particularly the changing polar ice. To do that, it uses a laser instrument called the Advanced Topographic Laser Altimeter System, or ATLAS, that precisely times how long it takes light particles to bounce off Earth and return to the satellite.

Mission managers at NASA's Jet Propulsion Laboratory in Pasadena, California, this week lowered the orbit of the nearly 12-year-old CloudSat satellite following the loss of one of its reaction wheels, which control its orientation in orbit. While CloudSat's science mission will continue, it will no longer fly as part of the Afternoon Constellation, or A-Train -- six Earth-monitoring satellites that fly in a coordinated orbit to advance our understanding of how Earth functions as a system.

The Sentinel-1 satellites of Europe's Copernicus Programme are being used to quantify the surface deformation of the disaster area around the Hualien earthquake.

The Spanish Earth observation satellite PAZ was successfully launched on 22 February 2018 at 15:17 CET from Vandenberg Air Force Base in California, United States, on board a Falcon 9 rocket.

With the aim of making the best possible use of existing satellites, ESA and Canada have made a deal that turns Swarm into a four-satellite mission to shed even more light on space weather and features such as the aurora borealis.

A repositioning of Europe's geostationary meteorological satellite fleet currently being undertaken at an altitude of 36,000km reached an important milestone today

The Sun bathes our planet in the light and heat it needs to sustain life, but it also bombards us with dangerous charged particles in solar wind. Our magnetic field largely shields from this onslaught, but like many a relationship, it's somewhat complicated. Thanks to ESA's Swarm mission the nature of this Earth–Sun coupling has been revealed in more detail than ever before.

On 31 January, NASA ended the Tropospheric Emission Spectrometer's (TES) almost 14-year career of discovery. Launched in 2004 on NASA's Aura spacecraft, TES was the first instrument designed to monitor ozone in the lowest layers of the atmosphere directly from space. Its high-resolution observations led to new measurements of atmospheric gases that have altered our understanding of the Earth system.

In its five years in space, the Landsat 8 Earth-observing satellite has racked up some impressive statistics: 26,500 orbits around the planet, 1.1 million "scenes" captured, a motherlode of images that represents 16 percent of all the observations in the 45-year Landsat archive.

The Sentinel-3B satellite scheduled for launch this spring, will be flying 30 seconds apart from its twin, Sentinel-3A, during the commissioning phase. This temporary tandem arrangement is to obtain better cross-calibration between instruments, thus reducing uncertainties in the multi-satellite time series and ensuring an overall high data quality.

ESA's Aeolus satellite has been particularly tricky to build. One of the main stumbling blocks has been getting its lasers to work in a vacuum, but recent tests on the satellite show that the vacuum or temperature of space won't get in the way of Aeolus measuring Earth's winds.

Why is the Arctic warming faster than the rest of the planet? Does mineral dust warm or cool the atmosphere? NASA has selected two new, creative research proposals to develop small, space-based instruments that will tackle these fundamental questions about our home planet and its environment.
A Chinese Long March 2D rocket successfully delivered seven satellites into a 300-mile-high (500-kilometer) orbit Friday 02 February, boosting international missions to measure seismic signals that could help predict future earthquakes, take detailed imagery of planet Earth and test compact camera, propulsion and radio technology.

On 20 January 2018, amateur astronomer Scott Tilley detected an unexpected signal coming from what he later postulated was NASA's long-lost IMAGE satellite, which had not been in contact since 2005. On 30 January, NASA — along with help from a community of IMAGE scientists and engineers — confirmed that the signal was indeed from the IMAGE spacecraft. Whatever the next steps for IMAGE may be, the mission's nearly six years in operation provided robust research about the space around Earth that continue to guide science to this day.

With new space missions come new and improved capabilities. And for those interested in what's happening to the ice on Planet Earth, we have two ventures this year that are going to make a major contribution to our understanding.
