- The Medium-Energy Neutral Atom (MENA) Imager instrument on the IMAGE
spacecraft detects energetic neutral atoms (ENAs) in the energy range 1-30 keV.
Like HENA, MENA provides images of the ring current, near-Earth plasma sheet,
and the nightside injection boundary. In addition, it images the ion
populations of the cusp. The lead investigator for the MENA experiment is Craig
J. Pollock, of Southwest Research Institute.

| Abstract from DBPedia | MENA, an acronym in the English language, refers to a grouping of countries situated in and around the Middle East and North Africa. It is also known as WANA (less commonly as SWANA, or NAWA), which alternatively refers to the Middle East as Western Asia (or as "Southwestern Asia" in the case of "SWANA") and is a way to refer to the geography instead of the political term. As a regional identifier, MENA is often used in academia, military planning, disaster relief, media planning (as a broadcast region), and business writing. Moreover, the region shares a number of cultural, economic, and environmental similarities across its comprising countries; for example, some of the most extreme impacts of climate change will be felt in MENA. Some terms have a wider definition than MENA, such as MENASA, MENAP or Greater Middle East, which extends to South Asia to include the countries of Afghanistan and Pakistan. The term MENAT explicitly includes Turkey, which is usually excluded from some MENA definitions, even though Turkey is almost always considered part of the Middle East.MENA（ミーナッ、アラビア語: الشرق الأوسط وشمال أفريقيا）とは、ポストBRICsとして注目が集まっている中東と北アフリカを合わせた市場。「Middle East（中東）」と「North Africa（北アフリカ）」の頭文字から「MENA」と呼ばれる。類義語にWANA（西アジアと北アフリカ）がある。 (Source: http://dbpedia.org/resource/MENA) |
