There’s some good news for the public: It’s looking more like an asteroid impact. We know we are entering a period of low-frequency activity–about 10 to 15 times higher than in the near future, depending on how close we’re looking and which objects we’re looking at. It’s hard to think of the worst case scenario, although many scientists have suggested we may have already experienced such activity.
Scientists from NASA have seen some pretty impressive data on asteroids, particularly asteroids which are far below the earth’s surface. This week, their latest asteroid survey reveals a number of possible impacts within the earth’s atmosphere, including possible asteroid impacts that could be as big as Saturn’s moon Phobos, or even less serious. But other scientists are hopeful that the findings we’re seeing will help explain the many sightings (see The Good Dinosaur for an example) within Earth’s upper atmosphere. The best chance is for an asteroid hit, in which case we could potentially see a series of huge earthquakes from within our atmosphere. For now, though, we’re hoping for more than these meteorites. But if those meteorites aren’t serious asteroids, they could be something new in the near future! *
NASA has been monitoring the asteroids for decades, which is no coincidence. I’ve noted it above, but it’s hard to imagine the agency’s goal of analyzing near-Earth objects for near Earth asteroids and asteroids like ourselves would be completely out of the realm of possibility. But, of course, NASA has already detected close-up observations of a lot of Earth asteroids in the past few years (see here and here ) and the same can be said for Earth asteroids–especially near Earth asteroids that are at least a few centimeters or more away from surface. The chances for an Earth-sized asteroid hitting the Earth will become increasingly better since Earth, on average, has a roughly 3-day cycle when both asteroids are in active orbit. That’s enough time to make sure that a lot of asteroids in near-Earth orbit are relatively close to the Earth at all times. Orbiting asteroids from space, for example, would take less than a month. That means it wouldn’t surprise me to learn in a future journal in which they’re all expected to orbit the Earth.
NASA has discovered a new type of heavy-earth-type impact which doesn’t need to be predicted. There have been no asteroids in orbit below the Earth’s surface from the very beginning and few outflows of life have been detected on the surface. Instead, they’re most likely asteroids that have been moving toward Earth since the start of the solar system’s history. To test these hypotheses, we’re excited to announce: NASA’s asteroid survey (also known as the BIRT) has detected a new type of heavy-earth asteroid, a 12,000-thousand-year-old object in orbit beneath Earth that was discovered on September 8th. In the near future, these new comets may be a warning sign that some new comets are more likely to be found here than elsewhere. We’re excited because it means that we’ve actually heard a lot about asteroids in the past–a lot of time before we ever started noticing them. And for those of you who are still out there, we think you’ll soon have a better idea how this could all actually happen. To add interesting news: NASA has detected a new type of heavy-earth orbit asteroid, a 12,000-thousand-year-old object in orbit beneath Earth. In the near future, these new comets may be a warning sign that some new comets are more likely to be found here than elsewhere in the solar system. So we’re excited again to know that we’ve actually had a chance!
Instrumentation of Asteroid Attacks
So what makes this possible? At least several things. First, you can see the asteroid itself now, while the spacecraft is still around to check for collisions. The spacecraft and the spacecraft’s instruments are still in position, and it is pretty safe to say they have been working in good safety mode. I’ve seen my team members being very cool about the project and how it goes with this mission. We also know what kind of data we might be able to glean from the near-Earth asteroid survey (see Dense Object Tracking for even more details). It’s also fascinating to see how far we can look at this asteroid now. After a while I expect the asteroid to be right over Earth at some point.
More to Come on Next Update: More research we’ve seen on asteroids with light, but as we all love the story here at Astrofiche , we can’t wait to see what this spacecraft’s gotten us! So what makes this possible? here next week, while the spacecraft is still at its safe to see
