Cubesats provide a valuable low-cost research space platform for institutions, universities, laboratories and space agencies, but could their use create a new hazard for the increasingly crowded orbital environment? Continue reading →
Through the analysis of isotopes trapped inside ancient quartz crystals, geochemists have realized that the Earth-shattering cosmic impact that laid waste to our young Earth and formed the moon happened 60 million years earlier than thought.
Billionaire Elon Musk said his private spaceflight company SpaceX has made some progress toward establishing a permanent colony on Mars — a longtime goal in the entrepreneur's push to help make humanity a multiplanet species.
