Nanosatellites are now the future of satellites because they are cost-efficient, smaller, and can be developed in a shorter period. Their smaller size does not limit the impact they can do to observe Earth's surface.
As scientists at various institutions are directly focusing on shark conservation, the Earth-observing satellites of NASA collect important information about the habitat of sharks, the ocean, in particular.
As SpaceX grows its constellation of Starlink satellites for global Internet access, more and more of these space objects can be spotted across the night sky - and a superfan has developed a portal to help everyone track these satellites.
Scientific evidence so far suggests that VLF radio waves interact with the charged particles in that region and could drain the belts after lightning storms have filled them up, creating an impenetrable barrier against radiation that protect spacecraft.
The United Launch Alliance (ULA) is forced to abort its mission again to launch a US spy satellite atop its powerful Delta IV Heavy Rocket, just a few seconds before lift-off on Wednesday, September 30.
