You may think that space technology is very advanced, but the truth is that both Voyagers 1 and 2

You might think that space technology is very advanced, but the truth is that the Voyagers, both launched since 1977, are exploring Interstellar Space using computer systems that are less powerful than your smartphone in your pocket! 📱💥

🛠️ What's the endurance trick? NASA engineers designed the system to be highly reliable (s) and have been closely supervising it from Earth for decades. (Careful mission management) The panels and components are built to withstand extreme environments in deep space.

🔋, despite their limited memory, they constantly send back invaluable scientific data. Currently, both craft are powered by RTG nuclear generators, which are gradually deteriorating. Engineers have to decide to shut down unnecessary systems to prolong the mission as long as possible.

✨ This is a testament to the determination and genius of human engineering design...Even old technology can explore the vast universe!

💬 What do your friends think? Durable technology and cutting-edge technology. Which is more important?

... Read moreจากประสบการณ์ที่ติดตามภารกิจของยานโวเยเจอร์ ผมรู้สึกทึ่งมากกับความสามารถของเทคโนโลยีที่แทบจะล้าสมัย แต่กลับอึดถึกทนเกินคาด การที่ระบบคอมพิวเตอร์ที่ติดตั้งบนยานในปี 1977 มีประสิทธิภาพต่ำกว่าโทรศัพท์มือถือในปัจจุบันนั้น แสดงให้เห็นว่าแรงบันดาลใจและความคิดสร้างสรรค์ของวิศวกร NASA มีบทบาทสำคัญในการออกแบบให้มีความน่าเชื่อถือสูงสุด (robust design) รวมถึงการบริหารจัดการภารกิจอย่างใกล้ชิดตลอดระยะเวลาหลายสิบปีช่วยให้การปฏิบัติภารกิจประสบความสำเร็จอย่างต่อเนื่อง อีกหนึ่งจุดที่ผมชื่นชมคือการใช้พลังงานจากเครื่องกำเนิดไฟฟ้านิวเคลียร์ RTG ที่แม้จะค่อยๆ เสื่อมสภาพ แต่ทีมวิศวกรก็หาวิธีในการประหยัดพลังงาน เช่น ปิดระบบที่ไม่ได้ใช้งาน เพื่อยืดอายุภารกิจให้ได้นานที่สุดในสภาวะอวกาศระหว่างดาวที่ท้าทาย ทั้งนี้ยังช่วยส่งข้อมูลทางวิทยาศาสตร์ที่ล้ำค่าเกี่ยวกับสภาพแวดล้อมนอกระบบสุริยะกลับมายังโลกได้ตลอดเวลา ประเด็นที่น่าสนใจคือ การออกแบบระบบที่เน้นความทนทานและความเรียบง่าย (durability and simplicity) กลับเป็นประเด็นที่เหนือกว่าการมุ่งเน้นแค่เทคโนโลยีล้ำสมัยเพียงอย่างเดียว เพราะสำหรับภารกิจในอวกาศที่ยาวนานมาก ความเสี่ยงของการเกิดความผิดพลาดในระบบสูงมาก การมีระบบที่วางใจได้ช่วยให้ภารกิจดำเนินต่อไปได้ถึงแม้เทคโนโลยีจะเก่าก็ตาม ดังนั้นสำหรับผม คำถามที่ว่าเทคโนโลยีที่ทนทานกับเทคโนโลยีล้ำสมัยอย่างไหนสำคัญกว่ากัน คงตอบได้ว่า "ทั้งสองอย่างต้องสมดุล" เทคโนโลยีสมัยใหม่ช่วยผลักดันขีดความสามารถใหม่ๆ แต่ความทนทานและการบริหารจัดการที่ดีจะเป็นตัวทำให้ภารกิจนั้นสำเร็จในระยะยาว โดยเฉพาะในสภาพแวดล้อมรุนแรงอย่างอวกาศระหว่างดาว สุดท้ายนี้ ยานโวเยเจอร์จึงไม่ได้เป็นแค่ยานอวกาศเท่านั้น แต่เป็นเครื่องพิสูจน์ความยิ่งใหญ่ของมนุษย์ที่สร้างสรรค์เทคโนโลยีด้วยความรอบคอบและความอดทน ทิ้งมรดกแห่งการสำรวจที่ทรงคุณค่าให้กับโลกและมนุษยชาติ
