宇宙飛行士の訓練は月面そっくりの火山島で　スペイン

　ここはアフリカ大陸の北西沖、スペイン領カナリア諸島のランサローテ島にあるロス・ボルカネス自然公園だ。
　黒ずんだ溶岩原やクレーター、溶岩洞を有するランサローテ島の地質は、月や火星と驚くほど似ている。そのため欧州宇宙機関（ＥＳＡ）や米航空宇宙局（ＮＡＳＡ）は長年、この島で宇宙飛行士の訓練を行ってきた。
　「この島の溶岩は月と非常によく似ています」と国際宇宙ステーション（ＩＳＳ）で二つのミッションを経験したゲルスト氏は言う。
　独特の地形は、１７３０年から６年続いた火山噴火に由来している。吐き出された火山灰と溶岩で、島の広大な部分が覆われた。
　ここで行われるＥＳＡの訓練プログラムは、古代の超大陸にちなんで「パンゲア」と名付けられた。宇宙飛行士の他、宇宙工学エンジニアや地質学者も参加する。岩石サンプルの特定・採集方法や微生物のＤＮＡの現場解析を学び、調査結果を宇宙管制センターへ送信する。
　パンゲアのプロジェクトリーダー、ロレダナ・ベッソーネ氏は「ランサローテ島には異なる種類の火山岩が多く、それが露出しています。樹木はありません」と語った。「はるか遠くまで見渡せます。まるで月面にいるみたいに」【翻訳編集ＡＦＰＢＢＮｅｗｓ】

Kneeling on the edge of a deep crater, astronaut Alexander Gerst uses a chisel to collect a sample of volcanic rock which he carefully puts inside a white plastic bag.
Gerst is not on the Moon, even if it looks like it. He is in the middle of Los Volcanes Natural Park on the island of Lanzarote in Spain's Canary Islands, off the northwest coast of Africa.
With its blackened lava fields, craters and volcanic tubes, Lanzarote's geology can be uncannily similar to that of the Moon and Mars -- so much so that the European Space Agency (ESA) and NASA have for years been sending astronauts to the island to train.
This place has lavas that are very, very similar to the ones that we find on the Moon, Gerst, a 46-year-old German astronaut with the ESA, told AFP.
He said the island was a unique training ground.
Gerst, who has completed two missions on the International Space Station, is one of about a dozen astronauts who have taken part in the ESA's Pangaea training course in Lanzarote over the past decade.
Named after the ancient supercontinent, Pangaea seeks to give astronauts as well as space engineers and geologists the skills needed for expeditions to other planets.
Trainees learn how to identify rock samples and collect them, do on-the-spot DNA analysis of microorganisms, and communicate their findings back to mission control.
Here, they are put into the field to experience the exploration of a terrain, which is something they will have to do on the Moon, said Francesco Sauro, the technical director of the course.
- Six-year eruption -
Gerst said the Pangaea training course, which he has just completed, helps prepare astronauts to work in a remote setting on their own.
If we run into a problem, we have to solve it ourselves, he said.
He completed the Pangaea training along with Stephanie Wilson, one of NASA's most senior astronauts. Both are possible candidates for NASA's next crewed Moon missions.
Named for the goddess who was Apollo's twin sister in ancient Greek mythology, NASA's Artemis programme aims to return astronauts to the Moon's surface as early as 2025, though many experts believe that time frame might slip.
Twelve astronauts walked on the Moon during six Apollo missions from 1969 to 1972, the only spaceflights yet to place humans on the lunar surface.
NASA and the ESA also regularly use Lanzarote's landscape of twisted mounds of solidified lava to test Mars Rovers -- remote controlled vehicles designed to travel on the surface of the Red Planet.
Lanzarote's unique geography stems from a volcanic eruption that began in 1730 and lasted six years, spewing ash and lava over large swathes of land.
Considered one of the greatest volcanic cataclysms in recorded history, the eruption devastated over 200 square kilometres (77 square miles) of terrain -- about a quarter of the island which is currently home to around 156,000 people.
- 'See far away' -
While there are other volcanic areas such as Hawaii that could also be used for astronaut training, Lanzarote has the advantage that it has little vegetation due to its desert-like climate.
You have a lot of different types of volcanic rocks in Lanzarote. And they are exposed. You don't have trees, said Pangaea project leader Loredana Bessone.
You can see far away, as if you were on the Moon, she told AFP.
The Canary Islands is making a big contribution to space exploration in another way too. The island of La Palma is home to one of the world's largest optical telescopes.
Located on a peak, the Great Canary Telescope is able to spot some of the faintest, most distant objects in the Universe.
La Palma was selected as the site for the telescope because of its cloud-free skies and relatively low light pollution.
