NASA internal emails indicate that the space agency was unaware of the 2019 OK asteroid described as an "urban killer" until the last moment on July 24.
The giant space rock the size of a football field was not discovered by researchers until 24 hours before it was set to turn along the Earth at a distance of only 48,000 miles, traveling at 55,000 miles per hour.
"Because there may be media coverage tomorrow, I warn you that in about 30 minutes an asteroid measuring 57-130 meters will travel the Earth only 0.19 lunar distances (~ 48,000 miles)," an email from July 24 Lindley Johnson, NASA's planetary defense officer, adding that the asteroid "was spotted about 24 hours ago. "[
NASA'S HEAD WARNS ASTEROID SEARCH TRUE: "WHY WE PROTECT ON A SINGLE PLANET, WE KNOW THAT WE WILL BE7" freedom of information and has also been confirmed by Fox News.
Swinburne University astronomy professor Alan Duffy describes the 2019 asteroid as an "urban killer" and an asteroid that "would have targeted more than 30 times the energy of the Hiroshima explosion" by the Sydney Morning Herald3
. NASA officials, including Johnson, were confused by the terminology used by Duffy and another Australian astronomer, quoted in the newsletter, saying "it would be helpful to ask them to think before Johnson also says that Australia" is essentially not nothing in support of planetary defense ana "according to internal emails.
The first emails received from Buzzfeed also indicate that NASA needs better detection of asteroids, specifically if it mentions that the ATLAS telescope and the PAN-STARRS Observatory "must detect slower objects."  Following media reports about the upcoming 2019 OK meeting, CNEOS issued a statement on August 6th that space rock damage could have been alarming.
"If the OK in 2019 had invaded and disturbed the Earth's atmosphere over land, the blast could have created local devastation to an area of about 50 miles," CNEOS wrote. "If the asteroid had entered the ocean, it would have been a bad day for any vessel in the area, but the sea would have absorbed most of the impact energy and it is doubtful that a tsunami would have been created. "
In a statement provided to Fox News, NASA public relations officer Alard Butel stated that NASA and other US agencies are directing international efforts to respond to possible near-ground impact  "In 2018, the White House released a National Strategy and Action Plan for the Preparation of Near-Earth Objects, which identifies key steps that US agencies need to take to better prepare the US – and the world – for discovery and response of potential impact, " ishe Beutel in an email to Fox News.
He added that NASA is geared to monitor all NEOs 140 meters and larger, noting that they are 35 percent full of NEOs of this size and "approximately 96 percent complete" for those 1 miles and more. "Strategic investments in our space programs will bring benefits to all of humanity as we continue to catalog all NEOs that pose a potential threat. One such investment is the planetary protection test administered by the Double Asteroid Redirect Test (DART), scheduled to launch in 2021 to demonstrate the possibility of using kinetic effects to alter the movement of an asteroid in space. "
NASA GAMES FOR MASSIVE ASTEROID STRIPS
The Space Agency will launch its first 20AA missionAnd22AndA22 awarded a $ 69 million contract to SpaceX, a space exploration company led by Ilon Musk, to assist with DART.
The next time such an asteroid will approach this close to Earth is a decade from now. Asteroid 99942 Apophis (named Egyptian god of chaos) will come within 19,000 miles of Earth on April 13, 2029, Fox News previously reported.
Asteroids entering within 0.05 astronomical units measuring 460 feet in diameter are known as "potentially dangerous" NEOs, according to NASA. These are being monitored by NASA's Center for Near-Earth Object Research (CNEOS). According to a 2018 report compiled by Planetary.org, there are more than 18,000 NEOs.
Last month, Musk said on a podcast that Apophis is not something to worry about, but eventually a "big rock" will hit Earth, and there is nothing we can do about it right now.
NASA has been preparing for planetary protection against asteroid impacts for years. A recent study has shown that Americans prefer a space program that focuses on the potential asteroid effects of sending humans back to the moon or Mars.
THE KILLER'S ASTEROID Comes – WE DON'T KNOW WHEN (BECAUSE TO BE DONE), BILL NYE SAYS
In 2016, NASA formalized its previous discovery agency program in its Science Mission Directorate. Last June, NASA unveiled a 20-page plan detailing the steps the US needs to take to be better prepared for NEOs – such as asteroids and comets – that come 30 miles from the planet.
In addition to enhancing the discovery of NEOs, tracking and characterizing capabilities and improving model forecasting, the plan also aims to develop technologies for diversion of NEOs, enhancing international cooperation, and establishing new emergency procedures and protocols for action.
Separately in April, NASA Administrator Jim Bridenstein said that an asteroid impact is not something that should be taken lightly and is perhaps the greatest threat on Earth.
"We need to make sure that people understand that this is not Hollywood, it is not about movies," Bridenstein said at the 2019 International Academy of Cosmonautics Planetary Defense Conference in College Park, Md., According to Space. com. "This is about protecting the only planet we currently know to host life, and this is planet Earth."
