The purpose of the Taranis mission is to study the transient luminous events that form over the clouds during thunderstorms around the globe. These TLE's, discovered in the years 90, are studied by the satellite Taranis orbiting at 700km altitude. Crédits : CNES. https://cnes.fr

NASA Langley scientists discuss how we're currently monitoring ozone recovery with an instrument on the International Space Station, and a future concept that would continue those measurements using innovative cubesats.

At the Airbus Defence and Space facility in Toulouse, France, ESA’s Aeolus wind satellite has been prepared for its launch on top of a Vega rocket from Kourou in French Guiana. Liftoff is currently scheduled for August. The development of this latest Earth Explorer started 16 years ago and has now finished. From orbit Aeolus will measure wind profiles on a global scale using a pioneering laser technology. These measurements will greatly benefit existing meteorological models and fill a gap in the observations of wind. ★ Subscribe: http://bit.ly/ESAsubscribe Learn more about Aeolus: http://bit.ly/AeolusESA

PACE's advanced technologies will provide unprecedented insight into Earth's ocean and atmosphere, which impact our everyday lives by regulating climate and making our planet habitable. Our oceans teem with life, supporting many of Earth's economies. New discoveries in Earth's living ocean will be revealed with PACE's global observations, such as the diversity of organisms fueling marine food webs and how ecosystems respond to environmental change. PACE will observe our atmosphere to study clouds along with the tiny airborne particles known as aerosols. Looking at the ocean, clouds, and aerosols together will improve our knowledge of the roles each plays in our changing planet. Red tides can come from harmful algal blooms near shore for a variety of reasons. PACE will help scientists monitor red tides.

On February 17, 2007, NASA launched a quintet of satellites to figure out the science behind Earth's most colorful auroras. The mission was titled THEMIS, which stands for Time History of Events and Macroscale Interactions during Substorms. Substorms happen when Earth's magnetosphere is disrupted by solar wind, or energetic particles flowing from the sun. This causes auroras to brighten and undulate in the sky. THEMIS helped scientists understand what triggers these substorms. All five THEMIS satellites launched on the same Delta II rocket before splitting up to orbit Earth in formation.

Night Sky Network members joined us to hear NASA's Theresa Arvidson share the history of the ongoing Landsat program, and update us about the upcoming Landsat 9 mission. Conceived in the 1960s, the Landsat program launched its first satellite in 1972. Landsat has gathered more than 45 years of information about Earth’s land surface, chronicling how it has changed over time, pioneering global land monitoring and making breakthroughs in assessments of natural resources, especially agriculture, forestry, and geology. The technical aspects of remote sensing advanced as the Landsat program proceeded to accumulate an unprecedented global data archive. This talk combines a little history, some technology, and a fair amount of science with lots of beautiful images of our Earth’s surface.

This animation shows IMERG rainfall accumulation estimates along Gita's track during the period from February 9 to13, 2018 when the tropical cyclone was moving over the southern Pacific Ocean area east of the International Date Line. This IMERG rainfall analysis indicates that tropical cyclone Gita frequently produced rainfall totals greater than 200 mm (7.9 inches) along its track. In some locations IMERG indicated that rainfall totals were close to 400 mm (15.7 inches). Credit: NASA/JAXA, Hal Pierce

Global sea level rise is accelerating incrementally over time rather than increasing at a steady rate, as previously thought, according to a new study based on 25 years of NASA and European satellite data. If the rate of ocean rise continues to change at this pace, sea level will rise 26 inches (65 centimeters) by 2100--enough to cause significant problems for coastal cities.

This is a visualization of the Equatorial Fountain process in the ionosphere, whereby ions are driven away from the equator forming ion density enhancements above and below the equator. This visualization is depicted near 50 degrees west longitude, where the magnetic equator crosses the geographic equator. Magnetic field lines near Earth are represented by the gold lines. Particles appear in a blue-white flash, representing the point where atoms are ionized, becoming positively charged and releasing an electron. Now these charged particles can 'feel' the near-Earth electric and magnetic fields. Their motion becomes a combination of circular gyromotion due to the magnetic field and E-cross-B drift. At higher altitudes, the electric field is weaker, reducing the vertical motion, and the ion motion becomes dominated by the magnetic field and gravity, allowing the ion to 'slide' down the magnetic field line back to Earth. At lower altitudes, the ions combine with free electrons in a process called recombination, represented by a red flash and fading of the particle trail. A slice of data from the IRI (International Reference Ionosphere) model represents the density of singly-ionized oxygen atoms is faded-in to compare to the particle motion. Red represents high ion density, green represents low ion density. The camera finally pulls out from Earth, providing an overview of the enhanced ion density (red) above and below the magnetic equator on the dayside of Earth. This enhancement was discovered by Edward Appleton in 1946. The Fountain effect is just one of the many of complex processes which occur in the layer of thinning atmosphere that forms Earth's interface to the space environment.

GOLD is a new NASA science mission that launches in January 2018 to explore Earth’s interface to space! GOLD stands for Global-scale Observations of the Limb and Disk. It will inspect the dynamic region of near-Earth space where space and Earth’s uppermost atmosphere meet. Historically difficult to observe, this is a little understood region that responds both to the lower atmosphere below and the tumult of space weather from above. GOLD is a hosted instrument roughly the size of a mini-fridge that will fly aboard a commercial communications satellite, SES-14 — and it’s the first NASA science mission to do so. Joining us are NASA scientists Sarah Jones and Alex Young and SES director of hosted payloads, Todd Gossett. They will share details of GOLD’s mission and why they’re excited about this particular launch. Learn more: https://www.nasa.gov/gold

Atmospheric carbon dioxide is the most important human-made greenhouse gas responsible for global warming. Oceans assist in removing carbon dioxide from the atmosphere: phytoplankton accumulate carbon dioxide through photosynthesis and their chlorophyll colours the ocean’s waters. Satellites use this colour to measure chlorophyll, which helps scientists to calculate how much carbon dioxide is absorbed or emitted.

The ozone layer protects life on Earth from ultraviolet radiation but it is also a powerful greenhouse gas. Satellites can provide measurements of atmospheric ozone and monitor distribution changes with the seasons. Credit: ESA/CCI Ozone and Aerosol teams/Planetary Visions

This timelapse video shows Sentinel-5P satellite, from final preparations to liftoff on a Rockot launcher, from the Plesetsk Cosmodrome in northern Russia, on 13 October 2017. The Sentinels are a fleet of satellites designed to deliver the wealth of data and imagery that are central to the European Commission’s Copernicus programme. This unique environmental monitoring programme is providing a step change in the way we view and manage our environment, understand and tackle the effects of climate change and safeguard everyday lives. Sentinel-5 Precursor – also known as Sentinel-5P – is the first Copernicus mission dedicated to monitoring our atmosphere. The satellite carries the state-of-the-art Tropomi instrument to map a multitude of trace gases such as nitrogen dioxide, ozone, formaldehyde, sulphur dioxide, methane, carbon monoxide and aerosols – all of which affect the air we breathe and therefore our health, and our climate. With a swath width of 2600 km, it will map the entire planet every day. Information from this new mission will be used through the Copernicus Atmosphere Monitoring Service for air quality forecasts and for decision-making. The mission will also contribute to services such as volcanic ash monitoring for aviation safety and for services that warn of high levels of UV radiation, which can cause skin damage. In addition, scientists will also use the data to improve our knowledge of important processes in the atmosphere related to the climate and to the formation of holes in the ozone layer. Sentinel-5P was developed to reduce data gaps between the Envisat satellite – in particular the Sciamachy instrument – and the launch of Sentinel-5, and to complement GOME-2 on MetOp. In the future, both the geostationary Sentinel-4 and polar-orbiting Sentinel-5 missions will monitor the composition of the atmosphere for Copernicus Atmosphere Services. Both missions will be carried on meteorological satellites operated by Eumetsat. Until then, the Sentinel-5P mission will play a key role in monitoring and tracking air pollution. Sentinel-5P is the result of close collaboration between ESA, the European Commission, the Netherlands Space Office, industry, data users and scientists. The mission has been designed and built by a consortium of 30 companies led by Airbus Defence and Space UK and NL.

ESA’s CryoSat and the Copernicus Sentinel-1 missions have been used to measure subtle changes in the elevation and flow of ice shelves that, in turn, reveals how huge canyons are forming underneath. Warm bottom ocean water is entering the cavity under Antarctica’s Dotson ice shelf and is stirred by Earth’s rotation. This is causing one side of the ice shelf to melt. The canyon, which has formed over 25 years, is now 200 m deep in places and the ice just above it is heavily crevassed, affecting the shelf’s future ability to buttress the ice on land.

Sentinel-5P has been fuelled and is now ready for launch from the Plesetsk Cosmodrome in Russia. Soon the satellite will join the rest of the Sentinel satellites in orbit as part of the Copernicus programme. Sentinel-5P’s purpose is to collect data on Earth’s atmosphere. It is an intermediary satellite which fills the gap between the past generation of atmospheric monitoring satellites, such as Envisat, and the future generation comprised of Sentinel-4 and -5. The raw data from Sentinel-5P will be sent to the DLR German Aerospace Center where it will be processed and archived. After processing, the data will be distributed to users worldwide.

Sentinel-5P will soon join the other Copernicus Sentinel satellites in orbit. Copernicus is the world’s largest environmental monitoring programme, and is operated by ESA and the European Commission. With Sentinel-5P, Copernicus will have its first satellite dedicated to the monitoring of atmospheric chemistry. These measurements are important to observe air pollution and climate change.

On 26 September 2017, the Mission Control Team worked 'on-console' in the Main Control Room at ESA's ESOC mission control centre in Darmstadt, Germany, in a long day of simulation training as part of preparations for Sentinel-5P launch, set for 13 October. By 12 October, the team will have conducted 26 day-long simulation sessions. Each runs for a full day, and employs sophisticated software to replicate the satellite and ground systems. Trainers can inject faults, errors and breakdowns into the simulation, testing the skill and knowledge of even the most experienced engineers and the teamwork and problem-solving abilities of everyone. “The human factor is the one that determines the success of the mission. There is no single responsibility, and it is great to see our teams working together,” says spacecraft operations manager Daniel Mesples. Why does everyone abandon the room at one point? This was an evacuation exercise ordered by ESOC Safety & Security, to simulate what to do if a fire or other hazard were to occur unexpectedly.

Having detailed knowledge of the shape of the seafloor is essential for generating nautical charts for navigation. It is also needed for exploration, fishing, coastal management and for understanding ocean currents that transport heat, nutrients and pollutants. While mapping the seafloor was traditionally carried out using sonar on ships, optical satellite data provide global, high-resolution maps that show ridges, valleys and sediments.
