De\u0219eurile spa\u021biale reprezint\u0103 o problem\u0103 major\u0103. Unele dintre ele sunt foarte mari, cum ar fi etapele de rachet\u0103 epuizate, navele spa\u021biale scoase din func\u021biune \u0219i c\u00e2teva unelte pierdute \u00een timpul ie\u0219irilor \u00een spa\u021biu. Cu toate acestea, majoritatea sunt mult mai mici.<\/p>\n<\/div>\n

Coliziunile cu resturi spa\u021biale de dimensiuni mari pot avaria sau chiar distruge o nav\u0103 spa\u021bial\u0103, a\u0219a cum s-a \u00eent\u00e2mplat \u00een cazul navei spa\u021biale franceze \u201eCerise\u201d \u00een 1996. Chiar \u0219i resturile mai mici pot provoca daune grave sau pot pune \u00een pericol un astronaut care efectueaz\u0103 o ie\u0219ire \u00een spa\u021biu.<\/p>\n

C\u00e2nd panourile solare ale Telescopului Spa\u021bial Hubble au fost aduse \u00eenapoi pe P\u0103m\u00e2nt \u00een 2002, acestea erau acoperite de cratere de impact cu diametrul de p\u00e2n\u0103 la 8 mm.<\/p>\n

\u00cen prezent, telescoapele \u0219i radarele monitorizeaz\u0103 peste 12.000 de fragmente de de\u0219euri cu dimensiuni de p\u00e2n\u0103 la 10 cm. Multe milioane de fragmente sunt prea mici pentru a fi \u00eenregistrate, cum ar fi particule de vopsea \u0219i praf.<\/p>\n

\u00cen mod normal, acestea nu ar reprezenta o amenin\u021bare, dar \u00een spa\u021biu, resturile se deplaseaz\u0103 cu vitez\u0103 mare. Chiar \u0219i particulele de praf se comport\u0103 ca ni\u0219te gloan\u021be minuscule. ESA abordeaz\u0103 problema resturilor spa\u021biale \u00een diverse moduri. Laboratorul Columbus de pe Sta\u021bia Spa\u021bial\u0103 Interna\u021bional\u0103 este protejat de un scut special.<\/p>\n

Centrul European de Opera\u021biuni Spa\u021biale (ESOC) monitorizeaz\u0103 cu mare aten\u021bie de\u0219eurile spa\u021biale. Acesta utilizeaz\u0103 un telescop de 1 metru situat \u00een Insulele Canare \u0219i un sistem radar amplasat \u00een Germania. De\u0219eurile microscopice sunt monitorizate, de asemenea, de satelitul Proba-1 al ESA \u0219i de un experiment al ESA desf\u0103\u0219urat pe Sta\u021bia Spa\u021bial\u0103 Interna\u021bional\u0103.
Aceste informa\u021bii permit ESOC s\u0103 ofere recomand\u0103ri cu privire la momentul \u00een care o nav\u0103 spa\u021bial\u0103 ar trebui mutat\u0103 pe o orbit\u0103 mai sigur\u0103. De asemenea, ele asigur\u0103 o avertizare timpurie cu privire la obiectele de mari dimensiuni care sunt pe punctul de a reintra \u00een atmosfer\u0103.<\/p>","protected":false},"excerpt":{"rendered":"
