NASA scientists have concluded that even a nuclear bomb will not be able to prevent a giant asteroid from destroying a large part of the Earth. A million miles away, this shocking result turned out.
According to the British newspaper “Daily Mail”, the study was conducted over a period of four days, from April 26 to April 29, and astronomers used radar systems, data imaging and other technologies such as the largest telescope in the world.
Scientists decided that six months is not enough time to prepare a spacecraft to destroy the asteroid, and that a nuclear bomb will not destroy the monstrous space rock.
In the exercise, called “ Space Mission Options for a Hypothetical Asteroid Impact Scenario, ” nine NASA scientists spent four days looking at how such an event would occur over a six-month period as if it were a true emergency.
Day 1 of Simulations – April 19, 2021:
The asteroid, named 2021, was discoveredPDCThrough the NEO Survey project run by the University of Hawaii for NASA’s Planetary Defense Program, the simulated asteroid was found 35 million miles away, and at this time it only had a 5% chance of affecting Earth on October 20.
Day Two of Simulations – May 2, 2021:
Astronomers analyzed the data they collected to improve the 2021 orbitPDC And the possibility of its impact, and the team used image data collected in 2014 for the asteroid’s previous approach to Earth.
This data allowed astronomers to reduce the uncertainty in orbit and conclude that the simulated asteroid has a 100% probability of hitting Earth in Europe or North Africa, and this is when the team quickly began to work on how to prevent 2021.PDC Impact on the ground.
Participants said space mission designers were looking to disrupt the asteroid before collision, but concluded that the short time period did not allow for a credible space mission, given the current state of technology.
Scientists also suggested shooting the asteroid with nuclear weapons, but the team found hidden hurdles. The simulations showed that in the event of a nuclear device contact, space rocks could be reduced to a less destructive size.
The simulation suggested a size of 2021PDC From 114 feet to half a mile, it’s not clear if a giant bomb could drop the asteroid.
Day Three of Simulations – 30th June 2021:
Astronomers around the world continued to track 2021PDC Every night, using the largest telescopes in the world, by doing this they improved the asteroid’s orbit and drastically reduced its projected area of influence to fall within Germany, the Czech Republic, Austria, Slovenia and Croatia.
Fourth day of simulation – October 14, 2021:
Just six days before collision, it was 2021PDC It’s now roughly 3.9 million miles from Earth, and it’s close enough to a radar Goldstone Solar System Lact Discovery and Analysis 2021PDC And greatly improve the asteroid’s size and physical properties.
This showed that the asteroid was much smaller than previously thought, reducing the area expected for damage from the collision.
Astronomers at this stage were able to narrow the region of impact to be centered near the borders of Germany, the Czech Republic, and Austria, and they determined that the asteroid has a 99% probability of impacting within this region.
“Every time we participate in an exercise of this kind, we learn more about who are the main players in a catastrophic event, and who needs to know the information,” said Lindley Johnson, NASA’s planetary defense officer.
“Ultimately these exercises help the global defense community communicate with each other and with our governments to ensure we all coordinate in the event that a potential future impact threat is identified,” Johnson added.
NASA has participated in seven impact scenarios, four at previous Planetary Defense conferences (2013, 2015, 2017, and 2019) and three jointly with the Federal Emergency Management Agency (FEMA).FEMA).
The joint exercises between NASA and the Federal Emergency Management Agency included (FEMARepresentatives from several other federal agencies, including the Ministries of Defense and State.
