Voyager 1 goes silent for two days, then restores contact on its own

وائجر 1 دو دن خاموش رہا، پھر خود ہی رابطہ بحال کر لیا

वॉयेजर 1 दो दिन चुप रहा, फिर खुद ही संपर्क बहाल कर लिया

Voyager 1 goes silent for two days, then restores contact on its own

Key points

اہم نکات

मुख्य बातें

  • NASA's Voyager 1, launched in 1977 and now more than 25 billion kilometres from Earth, stopped responding during scheduled contacts on 18 and 19 October.
  • Its signal returned on 20 October before controllers could send a fix.
  • Engineers found that one group of thrusters, which keep the probe's antenna pointed at Earth, had gone offline and backup thrusters had taken over.
  • ناسا کا وائجر 1، جو 1977 میں لانچ ہوا تھا اور اب زمین سے 25 ارب کلومیٹر سے زیادہ دور ہے، 18 اور 19 اکتوبر کو مقررہ رابطوں میں جواب دینا بند کر گیا۔ اس کا سگنل 20 اکتوبر کو واپس آ گیا، اس سے پہلے کہ کنٹرولرز کوئی حل بھیج سکیں۔ انجینئرز کو معلوم ہوا کہ تھرسٹرز کا ایک گروپ، جو پروب کے اینٹینا کو زمین کی طرف رکھتا ہے، بند ہو گیا تھا اور بیک اپ تھرسٹرز نے کام سنبھال لیا تھا۔ وجہ کی ابھی تحقیقات جاری ہے، اور مشن ٹیم نے کہا کہ یہ پہلی بار ہے جب انہوں نے ایسا رویہ دیکھا ہے۔ یہ پروب 18 نومبر کو زمین سے ایک لائٹ ڈے کی دوری پر پہنچنے والا ہے۔
  • नासा का वॉयेजर 1, जो 1977 में लॉन्च हुआ था और अब पृथ्वी से 25 अरब किलोमीटर से ज़्यादा दूर है, 18 और 19 अक्टूबर को तय संपर्कों में जवाब देना बंद कर गया। इसका सिग्नल 20 अक्टूबर को वापस आ गया, इससे पहले कि नियंत्रक कोई हल भेज सकें। इंजीनियरों को पता चला कि थ्रस्टर्स का एक समूह, जो प्रोब के एंटीना को पृथ्वी की ओर रखता है, बंद हो गया था और बैकअप थ्रस्टर्स ने काम संभाल लिया था। वजह की अभी जांच जारी है, और मिशन टीम ने कहा कि यह पहली बार है जब उन्होंने ऐसा व्यवहार देखा है। यह प्रोब 18 नवंबर को पृथ्वी से एक लाइट-डे की दूरी पर पहुंचने वाला है।

NASA's Voyager 1, launched in 1977 and now more than 25 billion kilometres from Earth, stopped responding during scheduled contacts on 18 and 19 October. Its signal returned on 20 October before controllers could send a fix. Engineers found that one group of thrusters, which keep the probe's antenna pointed at Earth, had gone offline and backup thrusters had taken over. The cause is still under investigation, and the mission team said it was the first time they had seen this behaviour. The probe is due to reach one light-day from Earth on 18 November.
