Ko te Whakamātautau Asteroid Asteroid Redirection Test (DART) a NASA, te misioni tuatahi o te ao ki te whakamatautau i te hangarau mo te tiaki i te Ao ki nga aitua asteroid, comet ranei, i whakarewahia i te Wenerei i te 1:21 am EST i runga i te SpaceX Falcon 9 roketi mai i Space Launch Complex 4 East i Vandenberg Space Force Base i California.

Kotahi noa te waahanga NASAKo te rautaki whakamarumaru aorangi nui ake a DART – he mea hanga, he mea whakahaere e te Johns Hopkins Applied Physics Laboratory (APL) i Laurel, Maryland – ka pa ki tetahi asteroid e mohiotia ana ehara i te whakatuma mo te Ao. Ko tana whainga he whakarereke paku i te nekehanga a te asteroid kia tika ai te ine ma te whakamahi i nga karu-a-papa.

Ka whakaatu a DART ka taea e te waka mokowhiti te whakatere motuhake ki te asteroid i whainga, ka tukituki ki a ia - he tikanga whakapohehe e kiia nei ko te paheketanga kinetic. Ko te whakamatautau ka whakarato i nga raraunga nui hei awhina i te whakarite mo te asteroid tera pea ka pa ki te whenua, mena ka kitea. Ko te LICIACube, he CubeSat e eke ana me te DART e whakaratohia ana e te Italian Space Agency (ASI), ka tukuna i mua i te paanga o DART ki te hopu whakaahua o te paanga me te kapua o nga mea kua peia. Tata ki te wha tau i muri mai i te paanga o DART, ka whakahaerehia e te kaupapa Hera a ESA (European Space Agency) nga rangahau mo nga asteroids e rua, me te aro nui ki te rua i mahue mai i te tukinga a DART me te whakatau tika o te papatipu o Dimorphos.

"Kei te huri a DART i te pakimaero putaiao hei meka putaiao, a he tohu mo te kaha me te mahi auaha a NASA hei painga mo te katoa," ko ta te DART. NASA Kaiwhakahaere Bill Nelson. "I tua atu i nga huarahi katoa e ako ana a NASA i to tatou ao me to tatou ao whenua, kei te mahi ano tatou ki te tiaki i taua kainga, a ka awhina tenei whakamatautau ki te whakamatau i tetahi huarahi pai hei tiaki i to tatou ao mai i te asteroid kino mena ka kitea e tetahi. kei te anga ki te whenua.”

I te 2:17 i te ata, ka wehe a DART i te wahanga tuarua o te roketi. He meneti i muri mai, ka whiwhi nga kaiwhakahaere miihana i nga raraunga waea mokowhiti tuatahi me te tiimata i te huarahi ki te whakatakoto i te waka mokowhiti ki tetahi waahi haumaru mo te tuku i ana raupapa solar. Tata ki te rua haora i muri mai, ka oti i te waka mokowhiti te whakatuwheratanga angitu o ana huinga ra e rua, 28-putu te roa, kua hurihia ki waho. Ka whakakahangia e raua te waka mokowhiti me te Evolutionary Xenon Thruster a NASA - Te miihini katote hokohoko, tetahi o nga hangarau maha e whakamatautauria ana i runga i te DART mo te tono a meake nei mo nga misioni mokowhiti.
