Voyager 2: mawasiliano kamili yamerejeshwa na kusitishwa  

NASA mission update on 05^th Agosti 2023 ilisema mawasiliano ya Voyager 2 yamesitishwa. Mawasiliano yanapaswa kuanza tena pindi antena ya chombo hicho itakaporatibiwa upya na Dunia katikati ya Oktoba 2023.  

On 4^th Agosti 2023, NASA had reestablished full communications with Voyager 2 following an interstellar “shout” from agency’s Deep Nafasi Network (DSN) facility in Canberra, instructing the spacecraft to reorient itself and turn its antenna back to Earth. The spacecraft responded and began returning science and telemetry data, indicating it is operating normally and that it remains on its expected trajectory.

Voyager 2 kwa sasa iko katika umbali wa saa 18.5 za mwanga (maili bilioni 12.3 au kilomita bilioni 19.9) kutoka duniani. Ilichukua saa 37 kwa wasimamizi wa misheni kujua kama amri hiyo ilifanya kazi.  

Hapo awali 01^st Agosti 2023, NASA Deep Nafasi Network (DSN) was able to detect a carrier signal from Voyager 2 which confirmed that the spacecraft is still operating. Commands sent on 21^st Julai 2023 ilikuwa imesababisha antena kuelekeza kwa digrii 2 kutoka kwa Dunia bila kukusudia. Kwa hivyo, Voyager 2 haikuweza kupokea amri au kusambaza data duniani.  

Voyager 2 imepangwa kuweka upya mwelekeo wake mara nyingi kila mwaka ili kuweka antena yake ikielekeza Ardhi; uwekaji upya unaofuata utafanyika tarehe 15^th Oktoba 2023 ambayo inapaswa kuwezesha mawasiliano kuanza tena.  

Voyager 2 ilizinduliwa kwanza, tarehe 20^th Agosti 1977; Voyager 1 ilizinduliwa kwa mwendo wa kasi na mfupi zaidi tarehe 5^th September 1977. Since their launches, Voyager 1 and 2 spacecrafts are continuing on their over-40-year journey and are now exploring interstellar nafasi where nothing from Earth has flown before. 

Voyager 1 kwa sasa iko katika umbali wa takriban saa 22.3 za mwanga (maili bilioni 15 au kilomita bilioni 24) kutoka duniani na inaendelea kufanya kazi kama kawaida. Ilichukua maarufu Dot ya rangi ya samawati photograph of Earth on 14 February 1990, from a record distance of about 6 billion kilometers before leaving the solar system. On 25th August 2012, Voyager 1 made history when it entered into interstellar nafasi.   

Voyager Interstellar Mission (VIM) inachunguza ukingo wa nje wa kikoa cha Jua. Na zaidi.
