When the two voyager spacecraft launched in 1977,they had a tough job ahead, their mission was to explore Jupiter and Saturn, two giant planets in the outer solar system, the journey would be wrong and difficult. If something broke, the space probes...
April: In the US, Hugo Gernsback, an engineer and businessman, publishes first issue of Amazing Stories, an early sci-fi magazine, which would make big contribution into popularization of space flight. A new and expanded edition of the "Exploration of the Outer Space with Reactive Vehicles" ...
Although an infinite conductivity is probably a good approximation in most of space the nature of the wind depends critically on many small, self-consistently determined, non-ideal domains, e.g. the conductivity of vacuum in polar and outer wind gaps, and the anomalous resistivity in regions of...

All told, I have enough stories to fill up an entire book as an eyewitness to NASA’s educational programs from 1998 through today, a 25-year history as missions have come and gone and we’ve learned so much more about space. Here I am posing by the Saturn V rocket at Johnson Space...
Growing stem cells on Earth is very challenging and limited to a few population doublings. The standard two-dimensional (2D) culture environment is an unnatural condition for cell growth. Therefore, culturing stem cells aboard the International Space Sta

Space weather effects arise from the dynamic conditions in the Earth’s space environment driven by processes on the Sun. While some effects are influenced neither by the properties of nor the processes within the Earth’s magnetosphere, others are critically dependent on the interaction of the imp...
