Gawo limodzi chabe la njira zazikulu zodzitetezera ku mapulaneti a NASA, DART idzakhudza asteroid yodziwika yomwe siili yowopsa padziko lapansi.

NASA's Double Asteroid Redirection Test (DART), ntchito yoyamba padziko lonse lapansi yoyesa ukadaulo woteteza Dziko Lapansi ku zoopsa za asteroid kapena comet, idakhazikitsidwa Lachitatu nthawi ya 1:21 am EST. SpaceX Falcon 9 rocket yochokera ku Space Launch Complex 4 East ku Vandenberg Space Force Base ku California.

Gawo limodzi chabe la NASANjira yayikulu yodzitetezera ku mapulaneti, DART - yomangidwa ndikuyendetsedwa ndi Johns Hopkins Applied Physics Laboratory (APL) ku Laurel, Maryland - idzakhudza asteroid yodziwika yomwe siili yowopsa padziko lapansi. Cholinga chake ndikusintha pang'ono kayendedwe ka asteroid m'njira yomwe ingayesedwe molondola pogwiritsa ntchito makina oonera zakuthambo.

DART iwonetsa kuti chombo cha m'mlengalenga chimatha kuyenda mokha kupita kumalo omwe chandamale cha asteroid ndikugundana nawo mwadala - njira yopatuka yotchedwa kinetic impact. Mayesowa apereka chidziwitso chofunikira chothandizira kukonzekera bwino zamlengalenga zomwe zitha kuwononga dziko lapansi, ngati zitapezeka. LICIACube, CubeSat yokwera ndi DART yoperekedwa ndi Italy Space Agency (ASI), idzatulutsidwa DART isanachitepo kanthu kuti ijambule zithunzi zakukhudzidwa ndi mtambo wotuluka wa zinthu zomwe zatulutsidwa. Pafupifupi zaka zinayi pambuyo pa kugunda kwa DART, pulojekiti ya ESA (European Space Agency) Hera idzafufuza mwatsatanetsatane ma asteroids onsewa, makamaka pa chigwa chomwe chinasiyidwa ndi kugunda kwa DART komanso kutsimikiza kwatsatanetsatane kwa kuchuluka kwa Dimorphos.

"DART ikusintha zopeka za sayansi kukhala zowona za sayansi ndipo ndi umboni waukadaulo wa NASA komanso luso lake kuti apindule onse," adatero. NASA Administrator Bill Nelson. "Kuphatikiza pa njira zonse zomwe NASA imaphunzirira chilengedwe chathu ndi dziko lathu, tikuyesetsanso kuteteza nyumbayo, ndipo mayesowa athandizira kutsimikizira njira imodzi yotetezera dziko lathu ku asteroid yowopsa ngati atapezeka kuti ali ndi kachilomboka. ikupita ku Dziko Lapansi.”

Nthawi ya 2:17 am, DART idasiyanitsidwa ndi gawo lachiwiri la rocket. Patangopita mphindi zochepa, oyendetsa mishoni adalandira chidziwitso choyamba cha telemetry ya ndege ndikuyamba njira yolozera chombocho kuti chikhale chotetezeka kuti chikayike zida zake zadzuwa. Pafupifupi maola awiri pambuyo pake, chombocho chinamaliza kutulutsa bwino kwa zida zake ziwiri, zautali wa mapazi 28, zotulutsa dzuwa. Adzapatsa mphamvu mumlengalenga ndi injini ya NASA ya Evolutionary Xenon Thruster - Commercial ion injini, imodzi mwamaukadaulo angapo omwe akuyesedwa pa DART kuti adzagwiritse ntchito mtsogolo paulendo wapamlengalenga.
