Its primary mission was to survey the entire sky in near-, mid- and far-infrared, through its 68.5cm (27.0in) aperture telescope.
Technical design
Its designed lifespan, of far- and mid-infrared sensors, is 550 days, limited by its liquid helium coolant.
Its telescope mirror is made of silicon carbide to save weight. The budget for the satellite was ¥13,4 billion (~US$110 million).
History
By mid-August 2006, Akari finished around 50 percent of the all sky survey.
By early November 2006, first (phase-1) all-sky survey finished. Second (phase-2) all-sky survey started on 10 November 2006.
Due to the malfunction of sun-sensor after the launch, ejection of telescope aperture lid was delayed, resulting the coolant lifespan estimate to be shortened to about 500 days from launch. However, after JAXA estimated the remaining helium during early March 2007 observation time will be extended at least until 9 September.
In the context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as Earth's Moon.
The world's first artificial satellite, the Sputnik 1, was launched by the Soviet Union in 1957. Since then, thousands of satellites have been launched into orbit around the Earth. Some satellites, notably space stations, have been launched in parts and assembled in orbit. Artificial satellites originate from more than 40 countries and have used the satellite launching capabilities of ten nations. About a thousand satellites are currently operational, whereas thousands of unused satellites and satellite fragments orbit the Earth as space debris. A few space probes have been placed into orbit around other bodies and become artificial satellites to the Moon, Mercury, Venus, Mars, Jupiter, Saturn, Vesta, Eros, Ceres, and the Sun.
On Through the Night is the debut album by English rock band Def Leppard, released in 1980. The album was produced by Tom Allom. It charted at No. 15 on the UK Albums Chart and No. 51 on the Billboard 200. The album features re-recorded versions of "Rocks Off" and "Overture", tracks from the band's original independently released EP, The Def Leppard E.P. Other tracks are re-recorded versions of early demos, some of which appeared on the First Strike and Warchild bootlegs. The album was certified platinum by the RIAA on 9 May 1989.
"Rocks Off", "Wasted", "Hello America" and "Rock Brigade" were released as singles. However, the versions of "Rocks Off" (titled "Getcha Rocks Off") and "Wasted" that appears on the singles is a different recording from that of the LP, as is its B-side, "Hello America". The single "Getcha Rocks Off" included the songs "Ride into the Sun" and "Overture".

Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain
Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

マウナケア上空を飛ぶ「あかり」衛星 "AKARI", the Japanese Infrared Satellite over Maunakea
マウナケアの上空を飛ぶ、日本の赤外線天文衛星「あかり」。
口径70㎝のヘリウム冷却宇宙望遠鏡で、赤外線天文学の分野に極めて大きな足跡を残した偉大な衛星。2006年打ち上げ。太陽同期軌道という、地球の昼夜境界線上を南北に周回する軌道を飛んでいます。
装置寿命を超える5年に渡って観測データを取得し続けたが、バッテリー不安定のために2011年運用を終了。今年の11月24日に運用終了10周年です。
日本の天文学者はみんな「あかり」の事は忘れません。この小さな軌跡に、ほんとに多くの人々の思いが凝縮されています・・・。

Akari All-Sky Map – Check out the full night sky in infrared!
This a full-sky map of the infrared emission detected by the Akari, a JAXA mission to observe the entire sky in infrared light.
The initial zoom starts with the typical oval projection you see of all-sky images (technical term is Mollweide projection), which zooms and stretches to the equirectanglular projection necessary for 360-degree videos.
Want to look around for longer than 30 seconds? Just press pause and then look around for as long as you like.

It was launched on 21 February 2006, at 21:28 UTC (06:28, 22 February JST) by M-V rocket into Earth sun-synchronous orbit. After its launch it was named Akari (明かり), which means light in Japanese. Earlier on, the project was known as IRIS (InfraRed Imaging Surveyor).
Its primary mission was to survey the entire sky in near-, mid- and far-infrared, through its 68.5 cm (27.0 in) aperture telescope.
Its primary mission was to survey the entire sky in near-, mid- and far-infrared, through its 68.5cm (27.0in) aperture telescope.
Technical design
Its designed lifespan, of far- and mid-infrared sensors, is 550 days, limited by its liquid helium coolant.
Its telescope mirror is made of silicon carbide to save weight. The budget for the satellite was ¥13,4 billion (~US$110 million).
History
By mid-August 2006, Akari finished around 50 percent of the all sky survey.
By early November 2006, first (phase-1) all-sky survey finished. Second (phase-2) all-sky survey started on 10 November 2006.
Due to the malfunction of sun-sensor after the launch, ejection of telescope aperture lid was delayed, resulting the coolant lifespan estimate to be shortened to about 500 days from launch. However, after JAXA estimated the remaining helium during early March 2007 observation time will be extended at least until 9 September.
Researchers from the University of Tokyo have used the data from two IR space telescopes, used on the AKARI and WISE satellites, to gain insights into the relationship between the dust of AGB stars and their brightness.
