As scientists continue to explore the possibility that water once existed on Mars, new evidence suggests that an asteroid strike may have once caused tsunamis on the red planet. For tsunamis to have taken place, water must have been present, so if this theory plays out, it could further the thinking that bodies of water once existed on the planet.
The research centers on a spot called the “Lomonosov crater,” long connected to debris having slid over the spot during a geographical shift. However, new thinking presents the theory that the crater was created by the impact of the asteroid hitting the planet, causing 150-mile waves.
Action movies have depicted what might happen if we learned an asteroid was heading toward Earth. As we prepared for mass destruction, what could we possibly do to save ourselves?
FEMA and NASA recently met to discuss that very scenario. Although participants believe it is unlikely to happen in our lifetime, they conducted a tabletop exercise on October 25th in El Segundo, California. This was the third in a group of exercises on the issue.
For the first time in history, officials say we have the ability to combat an approaching asteroid, but it’s important to continue to monitor, predict, and prepare for it. With the exercise, participants demonstrated the unique challenges that an asteroid would bring to emergency responders.
Scientists in Hawaii have discovered a new asteroid that may be a second companion to Earth. Like the moon, the 2016 HO3 always remains close to the Earth’s surface, leading scientists to label it a “quasi-satellite.”
This isn’t the first time scientists have pinpointed an asteroid that seemed to be an Earth companion. In 2003, the Lincoln Near Earth Asteroid Research (LINEAR) system spotted a near-Earth object that was later named 2003 YN107. However, the asteroid only remained in Earth’s orbit from 1997 to 2006 before moving away from our planet.
