Is there a risk of an asteroid colliding with Earth?

Published

on

Hypotheses are far away, at least in the near future, but missions are already being carried out, so we can be ready for such a development of events. Every day, small meteorites fall on the planet.

The more, the less likely

History is compulsory knowledge. 66 million years ago, a 16-kilometer asteroid crashed into the Gulf of Mexico, forming the Chicxulub crater and causing gigantic climate changes on Earth, leading to the extinction of more than 70% of the life forms that existed on Earth. planet. Dinosaurs included.

This was not the only case. It is enough to see that even today there are about 160 meteorite craters on the earth’s surface with a diameter of more than one kilometer. Does this mean we have reason to be concerned? Let’s do it step by step.

First, it is important to note that the larger the stony body we are talking about, the less likely it is to hit the Earth’s surface. And vice versa, the less, the more likely. In fact, small meteorites fall in some parts of the world with a daily frequency, often going unnoticed. Larger asteroids tend to hit our planet at much wider time intervals, which can range from many thousands to millions of years.

NEO

They are called NEOs (Near-Earth Objects). It is estimated that 90% of them are known, especially those above 140 meters. Thanks to the progress of planetary science, it is now possible to monitor them and calculate the degree of risk of a future collision with the Earth. NASA even has a center responsible for the continuous monitoring of these bodies. And the good news is that there is only a 0.16% chance of an object larger than 140 meters colliding with the Earth in this or the next century. But we can always encounter a smaller body. Or even one that is not yet known.

Osiris-REx and dart

That is why it is important to be prepared for all possibilities. And that is why several space missions are already underway (or planned) to study these bodies in detail and test technologies that allow them to be deflected aside if the need arises.

This is the case of NASA’s Osiris-REx mission, launched in 2016, targeting the nearly 500-meter asteroid Bennu with a 0.037% chance of hitting Earth between 2175 and 2199. The idea lies in the robotic arm of Osiris. -REx to collect a sample (expected to arrive on Earth in 2023) for further analysis.

Also look out for DART (Double Asteroid Redirection Test), a joint initiative between NASA and Johns Hopkins University whose main mission is to test unprecedented planetary defense technology to repel asteroids that could threaten our planet in the future. One such test was carried out late last month, when NASA deliberately hit the asteroid Dimorphos for the sole purpose of evaluating its ability to change trajectory. As a warning, the US agency emphasized the importance of conducting such experiments to save humanity “before there is a real need for it.” Oh, and the mission was successful.

‘My power is really low’: NASA’s Mars Insight rover prepares to launch from the Red Planet

Published

NASA Lander InSight He has delivered what may be his last message from Mars as he embarks on a historic mission to uncover the secrets of the Red Planet’s interior.

In November, the space agency warned that the probe could be running out of time as dust continued to condense and stifle InSight’s power.

“Spacecraft power generation continues to decline as windblown dust accumulates on solar panels,” NASA said in a statement. Update November 2. “The end is expected to come in the coming weeks.”

message shared NASA The InSight Twitter account tweeted on Monday: “My power is very low so this might be the last photo I can upload. Don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will—but I will.” Subscribe here soon. Thank you for staying with me.”

A geologist robot armed with a hammer and a seismograph first reached the barren expanse of Elysium Planitia in November 2018.

Since then, she has carried out geological excavations, taking the first measurements of earthquakes with a high-tech seismometer placed right on the surface of Mars.

Last month, the solar-powered car released an update to remind us of its time in space.

“I was lucky to live on two planets. Four years ago I made it safely to the second one, much to the joy of my family at first. Thanks to my team for taking me on this journey of discovery. I hope I can be proud of you.”

According to the published mission, Insight has measured more than 1,300 seismic events since it was published, and more than 50 of them had signals clear enough for the team to extract information about their location on Mars. Results.

The probe’s data also provided detailed information about Mars’ interior, liquid core, surprisingly variable remnants beneath the surface of an extinct magnetic field, climate and seismic activity.

old for Its launch in 2018NASA Chief Scientist Jim Green said the mission was “fundamental to understanding the origins of our solar system and how it became what it is today.”

NASA will not declare the mission complete until Insight confirms the arrival of two spacecraft orbiting Mars that are relaying their information back to Earth.

In 2018, the veteran rover announced the capabilities end of his 15 year stay Sending an incomplete photo of the Valley of Perseverance.

A severe dust storm darkened the sky around the solar-powered rover, shattering the sun and leaving behind a dark image with white spots due to camera noise. The transmission is interrupted before the complete image can be transmitted.
