                  NASA dicit:

                  Landsat 9 is the latest satellite to continue the legacy of global observations of Earth's land surface. With unmatched longevity, accuracy, and coverage, the Landsat program has been the cornerstone of global land imaging since 1972. Landsat 9 continues this tradition, and will carry us into the next 50 years of Earth observations. The two instruments aboard will make the most advanced measurements of any Landsat satellite.

                  The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey (USGS). Landsat satellites have been consistently gathering data about our planet since 1972. They continue to improve and expand this unparalleled record of Earth's changing landscapes for the benefit of all.

                  蚂蚁加速app官网下载地址 The complexity of aerospace systems is increasing exponentially. Both hardware and software subsystems are becoming more complex and encompassing systems' behaviour becomes difficult to model due to the dependencies, relationships, and other interactions between their components. Predictable behaviour of complex aerospace systems translates into the reliability of each of their subsystems.

                  Posted on September 21, 2018
                  Journalists present their findings about fraudulent pseudo-academic conferences and journals. There are fake science factories that are cashing in on millions of dollars every year, while giving studies scientific credibility. We should not underestimate the damage these pseudo-academic conferences can do to society.

                  Cryptocurrencies are here to stay and it is quite plausible that future human colonists spread across the solar system and beyond will use a decentralized cryptocurrency as opposed to a fiat currency issued by a central authority. The low transaction fees, the ubiquitous access, not being bound by exchange rates or interest rates, not being controlled by financial institutions who are serving foreign interests -- these are some of the advantages cryptocurrencies will enjoy in the thriving exo-economy.

                  Disruptive Technologies In The Space Industry
                  Posted on May 17, 2012
                  Disruptive technology is a very bizarre (and scary) concept, but it is not a bizarre or scary idea. The concept was introduced by Clayton Christensen. In one of his books, The Innovator’s Dilemma, The Revolutionary Book That Will Change the Way You Do Business, Christensen proves that, under certain circumstances, companies that do things right can lose their market share or even get out of business. He also presents a set of rules that can help companies capitalizing on disruptive innovation. While I am not trying to give a lecture on economics, I would like to understand how to apply (if possible) the principles of disruptive technologies to the space industry. A very good example is quite at hand… SpaceX.
