B Voyager 1: How Long Can We Communicate?

AI Thread Summary
Voyager 1 is expected to lose its ability to communicate with Earth by around 2025 to 2030 due to diminishing power from its nuclear reactors, which lose approximately 4 watts of power annually. NASA's Suzanne Dodd indicates that the spacecraft will have enough power to transmit until 2022 or possibly 2025. Currently, it takes over 33 hours for a round-trip message between Voyager 1 and Earth, and communication is limited to 6 to 8 hours daily on the Deep Space Network. As power decreases, the likelihood of maintaining contact will diminish significantly. The discussion highlights the urgency of understanding Voyager 1's impending communication limitations.

For how long will we still be able to communicate with the amazing Voyager 1?

If you click on the ≡ symbol at the top right of your screen you will find the PF SEARCH facility where a search on titles can discover discussions on the Voyagers. There is sure to be a recent discussion where you can learn much, and ask questions.

Good luck!

According to wikipedia, around 2025-2030 Voyager 1 will no longer be able to power any instrument. I assume that includes the transmitter, but I'm not sure.

Suzanne Dodd, the Voyager project manager at NASA's Jet Propulsion Laboratory, says the Voyager spacecraft are powered by a couple of nuclear reactors sitting on the back of the probe, but they will soon run out of steam. "The nuclear power sources lose about 4 watts of power a year," she says. At this rate, Dodd says, Voyager should have enough power to communicate with Earth until 2022 or maybe 2025.

At it current distance, a round-trip message from Voyager I to Earth and back again takes a little more than 33 hours. And Voyager scientists are allotted only 6 to 8 hours per day on the Deep Space Network, meaning there may not be somebody listening when Voyager is talking

Thank you! I am new here.
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
I am attempting to use a Raman TruScan with a 785 nm laser to read a material for identification purposes. The material causes too much fluorescence and doesn’t not produce a good signal. However another lab is able to produce a good signal consistently using the same Raman model and sample material. What would be the reason for the different results between instruments?
