Mars Expressi pardal salvestatud andmete abil on v\u00f5imalik kuulda, kuidas Phoenix punase planeedi pinnale laskub. P\u00e4rast Mars Expressi lennujuhtimismeeskonna poolt t\u00f6\u00f6tlemist on Phoenixi laskumise helid selgelt ja valjult kuuldavad.<\/p>\n

<\/a>Kuula kohe<\/a><\/p>\n<\/div>\n

Andmed Mars Expressi maandumismooduli sides\u00fcsteemist (MELACOM), mis j\u00e4lgis Phoenixi, saabusid Maale varsti p\u00e4rast Phoenixi maandumist.<\/p>\n

Kui Mars Express lendas \u00fcle<\/h2>\n

See animatsioon n\u00e4itab Phoenixi laskumise signaali, mille salvestas MELACOM.<\/p>\n

Animatsioonil n\u00e4htav piik sagedusvahemikus 7\u20138 kilohertsit n\u00e4itab Phoenixi enda poolt edastatavat signaali.
Maandumismoodulit on animatsioonis n\u00e4ha alates umbes 342 sekundist p\u00e4rast algust ja see kaob umbes 1085 sekundil. See n\u00e4itab, kuidas Mars Express v\u00f5tab vastu Phoenixi signaali ja j\u00e4lgib seda, samal ajal kui ta maandumismoodulile l\u00e4heneb; Mars Express j\u00f5udis Phoenixile k\u00f5ige l\u00e4hemale 1550 km kaugusele.
Kui Mars Express eemale lendas, avas maandumismoodul langevarju, eraldus kosmoselaevast ja maandus; seej\u00e4rel katkes maandumismoodulilt tulev signaal.<\/p>\n

Animatsioonis n\u00e4htav piigi nihkumine on tingitud niinimetatud Doppleri efektist, mis on v\u00e4ga sarnane sellega, mida kuuleme m\u00f6\u00f6duva rongi vilet kuuldes.<\/p>\n

Signaali j\u00e4lgimine \u00f5nnestus isegi laskumise ajal eeldatava \u00fclekande katkemise perioodi jooksul, kuni maandumismoodul kadus Mars Expressi vaatev\u00e4ljast. \u00dclekande katkemise periood on tingitud sondi \u00fcmbruses tekkivast ionisatsioonist, mis tugevneb, kui maandumismoodul laskub atmosf\u00e4\u00e4ri kaudu alla, ning sel ajal j\u00f5uavad l\u00e4bi vaid v\u00e4ga n\u00f5rgad signaalid.<\/p>\n

Salvestuse \u00fclej\u00e4\u00e4nud osa \u2013 algus ja l\u00f5pp \u2013 sisaldab taustm\u00fcra, mille tekitab Mars Express ise.<\/p>\n
