Asteroid 2004 MN4 will strike the Earth in April 2029.
Astronomers have now ruled out the possibility that asteroid 2004 MN4 will strike the Earth in April 2029. scientists from the Spacewatch Observatory near Tuscon, Arizona searched back through older observations to find some images of 2004 MN4 that were captured in March, 2004. This gave them enough data to recalculate the asteroid's path, and see that it doesn't pose a threat to the planet.
NASA's Opportunity rover has reunited itself with the heat shield that protected its entry into the Martian atmosphere almost a year ago, when it first arrived at Mars. After it was ejected, the shield crashed to the surface nearly 2 km away from Opportunity's landing spot. The rover will study both the heat shield, and its impact mark - now the freshest crater on Mars. Engineers will have an opportunity to understand how the heat shield performed during atmospheric entry, and scientists will get a chance to see what's beneath the surface of Mars.
