Space Technology Grand Challenges - NASA

Space Technology Grand Challenges The Space Technology Grand Challenges are an open call for cutting-edge technological solutions that solve important Space -related problems, radically improve existing capabilities or deliver new Space capabilities altogether. The Challenges are centered on three key themes: (1) Expand human presence in Space , (2) Manage in- Space resources, and (3) Enable transformational Space exploration and scientific discovery. These Challenges are designed to initiate thought and discussion among our nation s innovators about future NASA missions and related national needs.

asteroids that pass within 45 million kilometers of the Earth’s orbit. Some near earth objects are potentially large enough to be hazardous to the Earth in the event of a direct collision. Although impact with large objects is rare, the history of Earth indicates that such events do occur. A better understanding of the likelihood

Earth Timeline - NASA

How often do asteroids hit Earth? In the beginning of Earth's history, asteroids were constantly hitting the Earth. This was called the Heavy Bombardment Phase and ended 3.8 billion years ago, allowing a more stable environment for life to form. In Earth's recent history, there are fewer impacts, but they do still happen.
