    405E-446-Asteroid Homestead

    08/09/2026 | 2 mins.
    In the future one can envision a space mining family boarding a descendent of the SpaceX Falcon Heavy Launch Vehicle for a trip into low Earth orbit. A few hundred miles above the Earth's surface they would rendezvous with their asteroid mining spacecraft which will be their home for the next five years or so.

    915-Raining Comets

    04/09/2026 | 2 mins.
    The comets we observe generally start out as icy dirty snowballs of frozen gases like water and frozen carbon dioxide in the Oort cloud. If recent scientific analysis is correct, we are now witnessing a parade of comets produced by the passage of a star when our first ancestors began to roam the Earth in Africa.

    914-Deep Synoptic Array

    28/08/2026 | 2 mins.
    Looking into the sky at night with radio eyes you would not see the points of starlight forming the constellations instead you would see a very bright, colorful and wildly changing scene. In a desert valley near the Great Basin National Park Caltech is building the world’s largest radio telescope called the Deep Synoptic Array or DSA for short.

    403E-444-Near Comets

    25/08/2026 | 2 mins.
    Although no comet nucleus impact on the Earth has been conclusively identified, there is some evidence that suggests the 1908 Tunguska event in Russia, which knocked down trees over a 770 square mile area, could have been caused by a fragment of Comet Encke. However there is no doubt that the Earth's collision with dust and small debris left trailing from comets produces some of the meteor showers we enjoy so much.
