NASA has sent robotic probes to other planets in our solar system, and helped astronomers gaze into the depths of the universe. Beyond all that, NASA also has used its satellites and scientists to help us to
No financial help could be accepted from any government -- this means no government grants, no government subsidies, no NASA ships and no NASA parts. There was no lack of private donors, however. The star-studded list of contributors include Microsoft co-founder Paul Allen (Scaled Composites'...

NASA wants to change that. This would mean the end to throwing away lots of dirty clothes every year. Up to now, they simply had to put them with other waste in old supply ships to burn up in the atmosphere. NASA is working with the US company, Procter Gamble (P&G), to learn how...
(Image credit: NASA) What does this mean for us now? Human activity — through the emission of greenhouse gases into the atmosphere and the destruction of highly biodiverse environments, such as coral reefs and rainforests — represents a modern example of living systems imposing stress on ...
PureVPN does have one of the best interfaces with a separate tab for Netflix. It's also compatible with Amazon Prime Video, so if you've run out of content on Netflix, you can always look elsewhere for your fix. The Good The Bad ...
In November 2011, NASA launched the Mars Science Laboratory to study soil and rock for organic compounds or conditions that could help us understand if Mars is — or ever was — able to support the "habitability" of life on the planet. The Mars Science Laboratory is actually a function of...
