China's Space Program News Thread

[Richard Santos]

No that's definitely not true, there was a microwave on Skylab. In fact wasn't microwave specifically invented for space station use first before it went to become consumer product (and often touted as an example of tech invented for space program but eventually benefiting everyone)?

No, first commercial microwave oven was sold by Raytheon in 1955, 6 years before any men went into space. The first microwave designed for home use was released by Raytheon in 1967, 4 years before the first space station and 6 years before the first American space station.

Raytheon was first inspired to develop the microwave oven for cooking during WWII, when its engineers found standing in front of radar transmitter magnetron during tests can cause chocolate bars in their pockets to melt.

I thought the Germans already used microwave for cooking food back during WW2?

Anyway I think the first guy meant first microwave in space but Skylab apparently had one. What a silly first anyway to be worthy of attention. Imagine claiming being the first to use toilet paper in space or something equally ridiculous. Who cares.

I don’t believe the Skylab had a microwave onboard.

There are several reasons why microwave ovens have not been considered suitable for use on manned space missions. The most important reason is it is (for the inside of a spacecraft) a very powerful source of microwave radiation that must be totally shielded to prevent interference with onboard equipment or experiment, Which leads to the second reason, which is it not weight efficient because of the shielding, cooling requirements and that magnetron. The third is, contrary to how microwaves are advertised on earth, it is not energy efficient for cooking packaged food. Small thermal electric heated forced air convection heater used with matching food packaging is actually significantly more energy efficient for heating foil packaged food.

Hello friends, lately everybody are focused on CSS, Mars... and forgot about Yutu 2 Moon rover. Is there any news about it, last news i saw was from May 12th (traveled 709m by then), so more than 2 months nothing to hear about it. If somebody has any info i would apretiate to share it here.

Personally I wouldn't stand in front of a magnetron that outputs enough power to melt my choc bars.

A friend of my father worked on radars in the navy. It's customary for at least one ship in a navy base to keep their radar on at all times. So while he was working on radars he likely got scanned by near by radars at about the same height (or so I was told). Not sure if that is related to him later developing leukemia and as an after effect had to go on radiotherapy and dialysis. He died a few years ago.

It is still going like the energizer bunny. They are taking things slow because the surface on the back of the

Even those who don’t die usually lose their hair or become infertile at a fairly early age.

Every soldier on the military hates radars, (mil-grade)antennas etc. They know what this kind of stuff do the human body after repeated exposure. Honestly, I am betting that the generals and their buddies also know this but they still stay quiet due to the potential PR disaster with the wider public

I am sorry for your father. The higher up never care for the "grunts" and low level officers, anyone who has been on the military will tell you that

Will go back to topic now

Not my father but one of his friends. My dad also had an accident while he was in the navy. It involved him, his scooter, a poorly lit area of an on-base road and a barrier road block. He lost teeth and woke up in a military hospital bed, also on site. I think the base commander paid him a visit once and he can clearly remember the contrast of what his superior officer promised in front of the base commander and the treatment he received in the end. They did put up lighting around that area afterwards, though.

Anyway last rant and going back on topic.

This is a little fear mongering. Microwave is not ionizing. Therefore microwave does not cause radiation damage to tissues as ultraviolet, X-Ray, or high energy particle radiations would. Sufficiently intense microwave will cause heat burn damage to tissues by a different way, but with similar results, as holding your hand close to a infrared heat lamp, but that does not cause leukemia or hair loss.
