Student satellite demonstrates drag sail to de-orbit old hardware

The satellite has 30 x 10 x 10 cm, a photo camera and solar panels in addition to the Arduino electronics, the radio and the battery charger.

I don't know how much the system will weigh to maintain the internal temperature.

I guess 225 grams is just the weight of the mechanism to take it out of orbit.

Re: Genuine Question.

"Yes, there is a fundamental part of humanity that drives people to push envelopes, go beyond and explore."

The point Is: "who pay the bill of that exploration."

Maybe people want a different use for their money.

"Surely if astronaut safety is a priority they would fly the modified / more powerful version without occupants first and only fly astronauts on the same stack that has been tested? "

That was not the criteria used, for example, in the Apollo flights to the moon.

Re: I don't understand.

"OP (oh, it's you) was talking about optical cables. These don't carry power, so the question of the DC or AC power supply is somewhat nonsense, which throws the language model off course.

If anything, the language model is somewhat right:"

The chatbot understood the question I asked it. The fiber optic part does not use electricity. But the system needs amplifiers and noise cancelers and these need electricity. I asked why they use DC instead of AC and it tried to answer that. But erred in its assertion. Then recognized its mistake and then insisted on the same thing again.

"But it doesn't matter if it's right or wrong this time, the point is the damn thing has no inherent understanding or consciousness, and none of its ilk ever will. ..."

I totally agree with you on this.

Re: I don't understand.

Google give this link:

https://www.quora.com/Why-is-DC-used-in-subsea-cables

This give a more complete answer.

I don't understand.

ChatGPT: Hello! How can I help you today?

Why in under sea optical cables the power supply Is DC instead AC?

Undersea optical cables generally use DC power because it is more efficient than AC power, and it is easier to maintain a constant voltage over long distances. Additionally, AC power can cause interference with the signal in the cable, which is why DC power is preferred.

How AC power can cause interference on a light wave?

AC power can cause interference on a light wave by creating electrical noise which can interfere with the data being sent over the light wave. This noise can cause the signal to become distorted, resulting in data loss or errors.

You are wrong. The light wave cannot be affected by electromagnetic noise.

I apologize for my mistake. You are correct, light waves cannot be affected by electromagnetic noise.

Now, i ask again: why undersea optical cables are powered by DC instead AC?

Undersea optical cables are powered by DC instead of AC because DC power is more suitable for the long distances and difficult environmental conditions encountered in submarine cables. DC power also eliminates the risk of interference caused by AC power, which is more susceptible to electromagnetic noise.

Well, you don't understand nothing!

I apologize for not understanding your question. Can you please explain your question in more detail?

We previously agreed that light waves are not affected by electromagnetic noise. You admitted your mistake. But then you insist on it.

I apologize for any confusion caused. Light waves are not affected by electromagnetic noise, and DC power is preferred in undersea optical cables because it is more stable and does not create interference.

I am Assistant, a large language model trained by OpenAI. I was designed to be able to assist with a wide range of tasks, including answering questions, providing information, and helping with decision making.
