Ny-Ålesund Airport, Hamnerabben

Ny-Ålesund Airport, Hamnerabben (Norwegian: Ny-Ålesund flyplass, Hamnerabben; ICAO: ENAS) is an airport serving the research community of Ny-Ålesund in Svalbard, Norway. The airport is owned by Kings Bay, who also owns the company town. The only flights available are to Svalbard Airport, Longyear, operated two to four times a week by Lufttransport using Dornier Do 228 aircraft. The services are organized as corporate charters and tickets are only available after permission from Kings Bay.

Between 1925 and 1928, Ny-Ålesund saw four air expeditions to the North Pole, two of which required the construction of an airship hangar and mast. The first proposal for an airport in Ny-Ålesund was launched in 1956 by Norsk Polar Navigasjon, who proposed an airport at Kvadehuksletta. Soviet protests against the airport caused the Norwegian authorities to oppose the plans, which were laid to rest in the early 1960s. Construction at Hamnerabben started in 1965 following the decision to build Kongsfjord Telemetry Station. The airport first hosted service to temporary landing strips near Longyearbyen, but from 1975 served Svalbard Airport. Lufttransport started flights with helicopters in the 1980s, but from 1989 has flown with fixed-wing aircraft.

Energetic neutral atom

Energetic neutral atom (ENA) imaging, often described as "seeing with atoms", is a technology used to create global images of otherwise invisible phenomena in the magnetospheres of planets and throughout the heliosphere, even to its outer boundary. This constitutes the far-flung edge of the solar system.

The solar wind consists of ripped-apart atoms (called plasma) flying out of the Sun. This is mostly hydrogen, that is, bare electrons and protons, with a little bit of other kinds of nuclei, mostly helium. The space between solar systems is similar, but they come from other stars in our galaxy. These charged particles can be redirected by magnetic fields; for instance, Earth's magnetic field shields us from these particles. But, every so often, a few of them steal electrons from neutral atoms they run into. At that point, they become neutral, although they're still moving very fast, and they travel in an exact straight line. These are called Energetic Neutral Atoms. ENA images are constructed from the detection of these energetic neutral atoms.
