「超小型衛星」というものが今、熱い。本当に熱いのだ。何と言っても、一辺わずか35cmの立方体、大学が開発したこのサイズの人工衛星が、地球を飛び出し、金星に向かうような時代なのだ―――。 注:衛星の世界では、数百kgのものでも「小型」と呼ばれるため、それ以下のものを「超小型衛星」として区別する。しかし、明確な定義があるわけではない この衛星――地球を周回するわけではないので厳密に言えば"人工衛星"ではなく"人工惑星"になるが、慣例として"衛星"と表現する――を開発しているのは大学宇宙工学コンソーシアム(UNISEC)。2002年に設立されたNPO法人で、この団体には40を超える大学・高等専門学校(高専)の研究室が参加している。 これまでに、実際に10機を超える衛星が、UNISEC所属の大学・高専によって開発され、軌道上に打ち上げられた。もともとは教育から始まった取り組みであるが、大学発の衛星

「「プロジェクトが小さいうちに失敗を経験しておくべきなんですよ」と中須賀教授。大型衛星のコストは数百億円で、失敗したら取り返しが付かない。それに比べ、超小型衛星はケタがいくつも小さくダメージは少ない」- pm
