<\/a><\/p>\nCela lui donne un peu de l\u00e9g\u00e8ret\u00e9, d\u2019autant que j\u2019embarque le lecteur dans un v\u00e9ritable voyage virtuel vers la plan\u00e8te rouge, d\u00e9taillant chaque \u00e9tape comme la s\u00e9lection des astronautes, l\u2019architecture du vaisseau spatial, le vol, la vie et la survie \u00e0 bord, et le type d\u2019exploration que l\u2019on conduira une fois arriv\u00e9 sur Mars. Petit extrait\u00a0:<\/p>\n
L\u2019instant du d\u00e9part nous a rattrap\u00e9s. Les dix derni\u00e8res secondes r\u00e9sonnent dans les \u00e9couteurs. Un bruit sourd se double d\u2019une secousse subite, comme si un g\u00e9ant nous secouait par-derri\u00e8re. Une force sournoise nous repousse au fond de nos couchettes. L\u2019acc\u00e9l\u00e9ration augmente implacablement, et les vibrations montent en fr\u00e9quence.<\/i><\/p>\n
Depuis l\u2019aire des visiteurs \u00e0 Merritt Island, et tout le long de la c\u00f4te, nous devons pr\u00e9senter un magnifique spectacle, chevauchant une aveuglante flamme jaune, presque blanche, prolong\u00e9e par les volutes d\u2019une dense fum\u00e9e beige. [\u2026]<\/i><\/p>\n
En \u00e9crivant un livre, on doit rechercher ce que l\u2019on ne sait pas (c\u2019est-\u00e0-dire beaucoup de choses en g\u00e9n\u00e9ral) et ce fut l\u2019occasion pour moi de creuser des sujets sur lesquels je n\u2019avais pas eu le temps de me pencher, comme la psychologie des astronautes, ou encore la gestion d\u2019une serre sur Mars qui m\u2019a ouvert les yeux sur les contraintes \u00e9nerg\u00e9tiques et temporelles (c\u2019est tr\u00e8s chronophage) d\u2019une telle annexe. Extrait\u00a0:<\/p>\n
Si des panneaux transparents, opaques aux UV, sont envisageables, ne serait-ce que pour la vue et l\u2019\u00e9clairage d\u2019ambiance, il est clair que la solution id\u00e9ale est l\u2019\u00e9clairage \u00e9lectrique des plantes, le niveau d\u2019illumination et les longueurs d\u2019onde pouvant \u00eatre modul\u00e9s en fonction de chaque esp\u00e8ce. On sait par exemple que les laitues ne n\u00e9cessitent que de la lumi\u00e8re bleue et rouge pour leur croissance (c\u2019est pour cela qu\u2019elles sont vertes\u00a0: elles r\u00e9fl\u00e9chissent cette partie de la lumi\u00e8re, dont elles n\u2019ont pas besoin). On peut ainsi limiter la consommation \u00e9lectrique et r\u00e9duire la chaleur d\u00e9gag\u00e9e par les longueurs d\u2019onde inutiles. [\u2026]<\/i><\/p>\n
Ce livre n\u2019a pas pris une ride, et je l\u2019utilise toujours comme r\u00e9f\u00e9rence dans mes cours, car nous n\u2019avons h\u00e9las pas beaucoup progress\u00e9 dans les projets d\u2019envoi d\u2019\u00e9quipages sur Mars.<\/p>\n","protected":false},"excerpt":{"rendered":"
