How to stop an asteroid from hitting Earth

Science Voice: Bringer of chaos By Terry Mejdrich Freelance writer & former science teacher Apr 24, 2022 In ancient Egypt, Apophis was a mythological deity and the enemy of the sun god, Ra.  The deity was sometimes referred to as the Great Serpent. The sun was thought to be like a flaming ship or barge that Ra rode across the sky every day.  Ra represented life and light; Apophis represented darkness and chaos.  Every night when Ra descended into the underworld he would have to battle with Apophis and win in order to rise again in the next day. Apophis and Ra died with […]

OSIRIS-REx mission to be extended beyond initial plan limits By Greg Hahne Published: Tuesday, May 3, 2022 – 3:06pm NASA has green-lit the OSIRIS-REx mission to visit another asteroid that was once feared to hit Earth. The space agency extended the mission led by University of Arizona and renamed it OSIRIS-APEX. After dropping off its samples from a previous mission, the craft will be sent to study the near-Earth asteroid Apophis for 18 months, which will make close approach with Earth in 2029. Daniella DellaGiustina is the principal investigator for that mission. “We took a step back as a team and […]

  Unexpected Asteroid Smacks into Earth With Little Warning – Should We Be Concerned? 03-18-2022 Talia Wise An asteroid took astronomers by surprise recently, hitting Earth’s atmosphere just two hours after it was first detected by scientists. Thankfully, the stone wasn’t big enough to cause a major catastrophe on Earth. The refrigerator-sized cosmic rock, named 2022 EB5, is only the fifth asteroid spotted right before hitting the planet and is the first sighting of its kind since 2019. Last week, astronomer Krisztian Sarneczky noticed the asteroid while viewing space from the Piszkéstető Mountain Station in Northern Hungary. Sarneczky reported the […]

NASA: This huge asteroid could destroy our satellites in 2029 Published on March 4, 2022 at 11:34 AM by Maya Lou In a few years, a sizeable asteroid will come so close to Earth that it may impact our planet’s satellites. According to NASA scientists, one of the largest asteroids ever recorded will graze past Earth in 2019. The asteroid, named 99942 Apophis, is thought to be the size of the Eiffel Tower and its effects could be devastating for our planet’s satellites.

This ‘Space Shotgun’ Could Destroy Asteroids Hours Before They Hit The Earth Jannat Un NisaMarch 11, 2022 Asteroids may present a major risk to Earth, and therefore, NASA is working on a technology that may kill a space rock hours before it collides with the Earth. Scientists may now check the skies for potentially dangerous asteroids. Nearly 28,000 objects close to the Earth have been discovered by NASA’s Near-Earth Object Observations (NEOO) Program. This, however, is not enough. There should be a mechanism to defend ourselves if we identify a dangerous asteroid hanging over our heads. Fortunately, NASA’s Dart mission is on its […]

Near Earth Objects Cover-Up What’s Wrong with NEOWISE Nathan Myhrvold In a 2016 preprint and two papers published online in December 2017 titled “Asteroid thermal modeling in the presence of reflected sunlight” and June 2018, “An empirical examination of WISE/NEOWISE asteroid analysis and results” in the journal Icarus, I raised a number of scientific, methodological, and ethical problems with the NEOWISE asteroid research project and its published papers and results. In this article, I summarize the problems in a less formal way than the papers, and I explain how the scientific misconduct that I found can be verified by anyone. Unlike a formal research paper I […]

What Are Potentially Hazardous Asteroids and Is an Asteroid Predicted to Hit Earth? BY ROBERT LEA ON 1/13/22 AT 5:40 AM EST An asteroid over twice the size of the Empire State Building will make a close approach to Earth on January 18. The asteroid, 7482 (1994 PC1), will pass within around 1.2 million miles of Earth. This means that the asteroid is both close enough and large enough, with a diameter of around 1,000 meters, to be defined as a Potentially Hazardous Asteroid (PHA)by NASA‘s Center of Near-Earth Object Studies (CNEOS). This is despite the fact that there is no risk of 7482 (1994 […]

(Photo : MasterTux on Pixabay) Gigantic Asteroid Will Pass By Earth in 7 Years, Do We Have Defense Against Such Threats? By Rain Jordan Jan 07, 2022 11:23 PM EST A minor chance of striking Earth in 2068 was supposed to exist for the near-Earth asteroid, but radar measurements have ruled that out. Asteroid 99942 Apophis was recognized as one of the most dangerous asteroids that might hit Earth after its detection in 2004. As astronomers followed Apophis and its orbit became more known, that impact assessment altered. According to the findings of a new radar monitoring campaign combined with accurate orbit analysis, […]

A model of the Apophis asteroid. Image credits: Astronomical Institute of the Charles University: Josef Ďurech, Vojtěch Sidorin. The asteroid Apophis will pass close to Earth in 2029. Here’s why this is a good thing Earth’s gravity and Sun’s radiation can change its surface. by Paula Ferreira  January 5, 2022 The asteroid 99942 Apophis, first discovered in 2004, caused a bit of a panic and was briefly considered a risk-impact object. In 2021, the risk was ruled out by new observations — although the asteroid will pass close to Earth, it won’t cause any real problems. But it could give us a good […]

Will an asteroid hit the Earth? What are the chances of that and can such an object hit Poland? Alex Marcell The film caused a lot of questions – people are looking for information on the Internet whether the threat from outer space is really close to us. We clarify all doubts with an expert, prof. Tomasz Kwiatkowski from the Adam Mickiewicz University in Poznań, who has been studying asteroids approaching the Earth for many years, and Dawid with a fighter from the “Attention! Scientific Bełkot” channel. An asteroid hitting Earth is not only possible, but … it happens frequently. In […]

PI-Terminal Planetary Defense Terminal Planetary Defense   PI is a practical and effective method of planetary defense that allows for extremely short mitigation time scales as well as general use for longer warning time cases . The method involves an array of small hypervelocity kinetic penetrators that pulverize and disassemble an asteroid or small comet. This effectively mitigates the threat using the Earth’s atmosphere to dissipate the fragment cloud where the atmosphere acts as a “bullet proof vest” or “body armor”.  The effects of doing so are remarkable in their effectiveness. The key is to de-correlate the resulting acoustic blast […]

What Are Your Options When you’ve Only Got Hours or Days to Prevent an Asteroid Impact? OCTOBER 19, 2021 BY EVAN GOUGH Imagine a scenario where we detect an asteroid heading straight for Earth. Imagine that it will arrive in a couple of days, or worse, only a few hours. What could be done to stop it? It might be possible to protect ourselves and the planet on such short notice. But we’d have to test and build the right infrastructure to do it. When it comes to asteroids, humanity is engaged in a process of discovery. We send spacecraft out to […]
