Space weather disturbances can impact communications, navigation signals, and satellite orbits, and induce currents can trigger power outages on Earth — making the region a crucial area of study.GDC is a team of satellites that will study Earth’s upper atmosphere and provide the first direct global measurements of our planet’s dynamic and complex interface with the space environment. Working in tandem with the DYNAMIC spacecraft, scientists will be able paint a fuller picture of how energy transforms and travels throughout the upper atmosphere. GDC will fly at an altitude of 350-400 km.DYNAMIC is a pair of satellites that will work in tandem with GDC to study how changes in Earth’s lower atmosphere influence our planet’s upper atmosphere. Between the multiple spacecraft of GDC and DYNAMIC, simultaneous observations from different locations can give scientists a more complete picture of how atmospheric waves propagate up through this unique part of the atmosphere.

If you peer down on Earth from just 300 miles above the surface, near the orbit of the International Space Station, you can see vibrant swaths of red and green or purple and yellow light emanating from the upper atmosphere. This is airglow. Airglow occurs when atoms and molecules in the upper atmosphere, excited by sunlight, emit light in order to shed their excess energy. Or, it can happen when atoms and molecules that have been ionized by sunlight collide with and capture a free electron. In both cases, they eject a particle of light — called a photon — in order to relax again.

Together, GOLD and another NASA mission, Ionospheric Connection Explorer spacecraft, or ICON, will provide the most comprehensive of Earth’s upper atmosphere we’ve ever had.Above the ozone layer, the ionosphere is a part of Earth’s atmosphere where particles have been cooked into a sea of electrically-charged electrons and ions by the Sun’s radiation. The ionosphere is co-mingled with the very highest — and quite thin — layers of Earth’s neutral upper atmosphere, making this region an area that is constantly in flux undergoing the push-and-pull between Earth’s conditions and those in space. Increasingly, these layers of near-Earth space are part of the human domain, as it’s home not only to astronauts, but to radio signals used to guide airplanes and ships, and satellites that provide our communications and GPS systems. Understanding the fundamental processes that govern our upper atmosphere and ionosphere is crucial to improve situational awareness that helps protect astronauts, spacecraft and humans on the ground.GOLD, in geostationary orbit over the Western Hemisphere, will build up a full-disk view of the ionosphere and upper atmosphere every half hour, providing detailed large-scale measurements of related processes — a cadence which makes it the first mission to be able to monitor the true weather of the upper atmosphere.

The absence of magnetic protection allows the supersonic solar wind flow to directly interact with the Martian ionosphere (an almost fully ionized region of the Mars upper atmosphere). When the velocity of the solar wind increases, the Martian ionosphere is compressed and the ionopause (a boundary layer between the ionosphere and the solar wind) is displaced to lower altitudes. The ions of planetary origin such as O+ and O2+ escape from the upper atmosphere of Mars due to solar wind induced scavenging processes. Many more planetary ions are scavenged when the solar wind velocity increases because a much larger part of the planetary atmosphere is exposed to the solar wind as the ionopause is pushed inwards towards the planetary surface. There are some indications that the solar wind flow, as well as the Sun's x-ray and extreme ultraviolet radiation, were much more intense early in solar system history. It is thought that some 3.5 billion years ago, these extreme interplanetary conditions may have caused a much larger rate of water loss from the Martian atmosphere. We estimate that the solar wind scavenging pictured here under the extreme conditions in the early solar system would have caused the loss of a 10 meter global equivalent ocean layer from Mars over the last 3.5 billion years. This loss is less than one tenth of the 156 m global equivalent ocean layer estimated to have existed on early Mars using the Mars Global Surveyor observations.
