Prive\u0219te \u00een jur. Pare evident c\u0103 totul este alc\u0103tuit din solide, lichide \u0219i gaze. Cu toate acestea, ochii t\u0103i sunt indu\u0219i \u00een eroare. Cea mai mare parte a Universului nu este alc\u0103tuit\u0103 din materie obi\u0219nuit\u0103. \u00cen schimb, se pare c\u0103 este alc\u0103tuit \u00een mare parte din misterioasa materie \u00eentunecat\u0103 \u0219i din \u0219i mai misterioasa energie \u00eentunecat\u0103. Pentru a afla mai multe despre acest Univers invizibil, un nou instrument puternic, cunoscut sub numele de Spectrometrul Magnetic Alpha (AMS-02), urmeaz\u0103 s\u0103 fie livrat la Sta\u021bia Spa\u021bial\u0103 Interna\u021bional\u0103 (ISS).<\/p>\n<\/div>\n

AMS-02 va fi transportat la Sta\u021bie la sf\u00e2r\u0219itul lunii aprilie, \u00een cadrul ultimului zbor al navetei spa\u021biale Endeavour. La bord se vor afla, de asemenea, astronautul ESA Roberto Vittori \u0219i cinci colegi ai s\u0103i. Roberto este primul astronaut ESA care va zbura de trei ori c\u0103tre Sta\u021bie. El va fi, de asemenea, ultimul european \u2013 \u0219i ultimul non-american \u2013 care va zbura cu naveta spa\u021bial\u0103.<\/p>\n

Una dintre sarcinile sale va fi aceea de a folosi bra\u021bul robotic al navei Endeavour pentru a ridica detectorul de particule AMS-02 din compartimentul de marf\u0103 \u0219i a-l fixa pe Sta\u021bia Spa\u021bial\u0103 Interna\u021bional\u0103 (ISS). Instrumentul, care c\u00e2nt\u0103re\u0219te \u0219apte tone, va func\u021biona timp de cel pu\u021bin trei ani. Acesta va m\u0103sura ce se \u00eent\u00e2mpl\u0103 atunci c\u00e2nd particule de mare energie, cunoscute sub numele de raze cosmice, ajung din galaxii \u00eendep\u0103rtate. Orice particule ciudate create de impactul acestor raze cosmice ar putea furniza dovezi privind existen\u021ba antimateriei sau a materiei \u00eentunecate.<\/p>\n

Se consider\u0103 c\u0103 \u00een timpul Big Bang-ului s-au creat cantit\u0103\u021bi egale de materie \u0219i antimaterie, dar antimateria pare s\u0103 fi disp\u0103rut din Universul actual. Se consider\u0103 c\u0103 materia \u00eentunecat\u0103 este mult mai r\u0103sp\u00e2ndit\u0103 dec\u00e2t materia obi\u0219nuit\u0103, dar aceasta nu a fost \u00eenc\u0103 detectat\u0103 direct. Denumirea \u2018DAMA\u2019, atribuit\u0103 misiunii lui Roberto Vittori, reflect\u0103 aceast\u0103 c\u0103utare a materiei \u00eentunecate.<\/p>","protected":false},"excerpt":{"rendered":"
