A difference is that Jeff hates paying taxes. There are shells around shells that were created to ensure exactly that. Or, when margins started to climb, he would call Jassy and tell him to cut pricing so that they didn't profit from AWS. Any time they had profit was money the government would tax,...
Jump to postSpaceX told their satellites can naturally deorbit themselves and burn in the Earth's atmosphere. Do they have another deorbiting system?
Jump to postThe ISS recently suffered a clash with a piece of space junk that hit its robotic arb. Isn't it an important signal for us to start doing something with it...
Jump to postI guess it`s impossible to decrease the number of launches. I heard that some space agencies are going to make some ``cleaning`` missions. I guess the easiest way to cope with space junk is to make them burn down in the atmosphere. However, it depends on the size of some space debris. It can be so ...
Jump to postThe most obvious decision we can take is to reduce the number of launches. However, we all understand that it's impossible now and will hardly ever be possible. That's why space agencies work on numerous projects that aim to clean the orbit. Some of them presuppose the use of satellites, and they s...
Jump to postGuys! Chinese rover took its first drive on Mars and made China the second nation that managed to drive a rover on Mars. It happened 3 days ago. That`s interesting! looking forward to getting to know something interesting from this Chinese rover. This is a great achievement for the Chinese space ex...

Jump to postPracticality is important, all aviation requires the highest reliability from its engines. Why fool around with anything other than virgin fuels to ensure that reliability. There are plenty of processes - like cement kilns, marine freighters, large boilers, even on land stationary gas turbines wher...
Jump to postAnd what about 3d printing for satellite manufacturing? Can smallsats or CubeSats be made using this technology? I think it would help satellite launchers to reduce production costs and equip their sats with high-quality payloads, such as these CubeSat cameras that can be used for high-resolution re...
Jump to postWhen they plan to finish this space station? Also, I want to know how it will differ from the existing ISS? This amateur but well informed Channel has a good overview, made before the whole booster incident; https://www.youtube.com/watch?v=06GUEkc4EEA Interesting to note that even though a search f...

Jump to postDoes this machine print the elements of coating for the spacecraft or something more important? I heard about the use of 3d printing in aerospace engineering but never went into details.
Jump to postWhat if we launch a satellite to SSO? Can it be used for Earth observation? I recently explored one company called Dragonfly Aerospace; it produces imagers and cameras for various types of satellites. Here you may learn more about the,=m https://dragonflyaerospace.com/mantis/.
Jump to postI consider this kind of fuel a good invention, however as I have already said it is only useful for some small launches and it is not good for some long space journeys. Also, according to the words of scientists who worked on ecosence fuel, this fuel is eco friendly, so this fact makes it even bett...
Jump to postOn April 25, Ingenuity took its third flight. The altitude was the same, but the speed and distance significantly increased.

You've already mentioned the problem of space debris, so I want to emphasize the fact that the government and private enterprises spend huge amounts of money on launches every year. I understand that building rockets and launch vehicles can't be cheap, but I think there are certain ways to save some...
Jump to postWow, rocket fuel made from plastic waste is something really new for me. I don't understand why people negatively perceive everything. Our aerospace industry develops, and it's amazing. It's too early for me to make any conclusions about the effectiveness of this fuel, I need to spend time finding m...
Jump to postWe have that since a veeeeeeeeeeery long time. It's basically photography at various wavelengths. Also, satellite-based radar is nowadays good enough to register soil erosion / deposition at centimeter precision. Observing Global Desertification with the Assistance of Space Technology is a very use...
Jump to postDragonfly Aerospace. It's a satellite imager manufacturer from South Africa. This company was established not so long ago, but it had already launched its own satellite and imager. The cameras they produce have good characteristics and help scientists obtain a lot of useful information about our env...
Jump to postI don't think any similarity between Black Arrow and Skyrora rockets. Did you want to tell that Skyrora XL is a copy of Black Arrow? I'm afraid you're completely wrong. Users above tried to emphasize that all modern rockets are environmentally friendly, but it's not so. If that were the case, so-cal...
Jump to postPerhaps, NASA gives a chance to private companies to test their spacecraft and lunar landers. It's a good way to identify a forward-looking and promising company that can become NASA's partner in the future. I agree with you: it may be an attempt to set ownership or create a marketplace of space res...
Jump to postMany experts tell the SLS project is a failure, but I don't want it to be true. I see how much money was spent on this project, and I don't want it to fail. I hope NASA will solve all problems and send at least an uncrewed mission this or next year.
Jump to postGuys, I want to ask your opinion. What do you think about countries that frankly copy SpaceX's concepts? Is it good or bad for the company and the reputation of this country?
Jump to postCongrats to everyone! 2021 starts well enough. I'm glad that lockdown didn't prevent space agencies from achieving their aim and making another contribution to Mars exploration. The number of instruments these rovers use lets us obtain more detailed information about its climate, soil, radiation lev...
Jump to postI was also surprised by this because this country has a doubtful reputation; however, its location explains everything. As you know, the best location for a spaceport is the equator. It lets spacecraft take the most out of the rotational energy of Earth. So, why not save fuel when there's a possibil...
