Rolling coverage: Brace for hypothetical asteroid impact

Challenging questions need to now be asked. How do we deflect the asteroid?
Designs suggest the asteroid might affect anywhere within a threat passage going from Southern to Western Africa, across the Atlantic and approximately North America.

More details are can be found in on the final twitter thread from ESA Operations:.

** This post explains a completely theoretical asteroid impact situation, that played out throughout this years Planetary Defense Conference **.
Conference wrap-up.
Take house messages:.
— Asteroid impacts are the only natural disaster we can avoid.
— Fortunately, we do not get much practise in reacting to large asteroid impacts. This suggests hypothetical impact circumstances are an essential tool in preparing for a range of worst case situations. (This year, much of the imaginary asteroid 2019 PDC was deflected using multiple kinetic impactors, however the head of this contact binary remained on an accident course with Earth, set to ruin New York. Questions about reconnaissance missions, nuclear alternatives and evacuation and emergency readiness became essential to the international reaction. See below for a day-to-day break down of what occurred.).
— ESAs Near-Earth Object Coordination Centre (among others) is continuously figuring out the paths of near-Earth asteroids, and computing their threat. All this information is publically available! Subscribe to the monthly asteroid newsletter and inspect out the site, here.
— Asteroids move in specified orbits– they are predictable! When weve discovered an asteroid and observed it over a period, we can figure out where it will be at any point in the future and therefore comprehend if it will ever pass near Earth.
— With excellent observations, we can have years– decades or even centuries– to get ready for a potential asteroid impact.
— Asteroid deflection is a reality– an international cooperation will see NASA fly their DART, Double Asteroid Redirection Test, spacecraft into the Didymoon asteroid, with the objective of modifying its orbit. ESAs Hera objective will follow up and observe the effect– an essential part of understanding the impacts of a kinetic impact. Discover out more, here.
— Astronomers, amateur-astronomers, space firms and observatories are continuously monitoring our skies. ESAs upcoming Flyeye telescope will play an important function in the search for risky area rocks.

— Asteroid deflection is a truth– a global cooperation will see NASA fly their DART, Double Asteroid Redirection Test, spacecraft into the Didymoon asteroid, with the goal of altering its orbit.– Fortunately, we dont get much practise in responding to large asteroid effects. (This year, much of the imaginary asteroid 2019 PDC was deflected utilizing numerous kinetic impactors, however the head of this contact binary remained on an accident course with Earth, set to damage New York. In reaction to theoretical asteroid # 2019PDC– set to effect Denver, Colorado– 3 kinetic impactor missions were sent out to crash into the space rock and push its orbit away from Earth.– 2019 PDC is travelling in an eccentric orbit, extending 2.94 AU at its farthest point from the Sun (in the middle of the primary asteroid belt), and 0.94 AU at its closest.

Monday 29 April: Day one.
First press release on the detection of asteroid 2019 PDC, comparable to what would be released needs to a real harmful asteroid be discovered.
ESAs Head of Planetary Defence reacts to the stressing discovery:.
” 1 in 100 might not seem like a lot, however considering the damage an asteroid of this size might cause– this is something we would need to take very, very seriously.”.
Paul Chodas, creator of this years effect circumstance broadens on the complexities of the case:.

Setting the scene: Planetary Defense Conference 2019.
Every 2 years, asteroid experts from around the world come together to pretend an asteroid impact looms. Throughout these week-long impact scenarios, participants do not understand how the circumstance will develop know from one day to the next however should make plans based on the day-to-day updates they are given.
For the very first time, ESA will be live tweeting the theoretical impact scenario from the heart of the Planetary Defense Conference (PDC) in Washington DC– so youll learn the news as the experts do. What will they do? What would you do?

This years asteroid– 2019 PDC.
The scene has actually been set for this years theoretical impact situation. Sensible, is it is entirely imaginary and does NOT explain a real asteroid effect.
— An asteroid was discovered on 26 March 2019 and has actually been provided the name “2019 PDC” by the IAUs Minor Planet.
— Initial computations recommend the orbit of 2019 PDC will bring it within 7.5 million km of Earths orbit. (Or, within 0.05 AU of Earths orbit. One AU is the mean range between the Sun and Earth, equal to 149 597 870.7 km).– 2019 PDC is taking a trip in an eccentric orbit, extending 2.94 AU at its farthest point from the Sun (in the middle of the primary asteroid belt), and 0.94 AU at its closest. It finishes one complete orbit around the Sun every 971 days (2.66 years). See its orbit in more information here.
— The day after 2019 PDC is discovered, ESA and NASAs effect tracking systems recognize numerous future dates when the asteroid could strike Earth. Both systems agree that the asteroid is most likely to strike on 29 April 2027– more than eight years away– with a very low possibility of effect of about 1 in 50 000.
— When it was very first discovered, asteroid 2019 PDC was about 57 million km from Earth, equal to 0.38 Astronomical Units. It was travelling about 14 km/s, and slowly getting brighter.
— Very little is understood about the asteroids physical residential or commercial properties. From its brightness, professionals identify that the asteroids mean size could be anywhere from 100-300 meters.
— Asteroid # 2019PDC continued to approach Earth for more than a month after discovery, reaching its closest point on 13 May. The asteroid was too far away to be identified, and it is not anticipated to pass close to Earth until 2027– the year of effect.
— Astronomers continued to keep an eye on the asteroid for a month after its preliminary detection, which offered them with more details about the items trajectory, and have actually now found that the chance of effect is rapidly increasing. By 29 April 2019, (the very first day of the Planetary Defence Conference), the likelihood of effect has actually increased to 1 in 100.

Friday 3 May: Day 5.
Ground-based observations, including ranging measurements by the Arecibo Observatory in Puerto Rico, have actually narrowed down the effect area. 2019 PDC is forecasted with certainty to effect over the Central Park area in New York City– simply 10 days from now.
The U.S. Federal Emergency Management Agency has asked for daily updates from the International Asteroid Warning Network on the anticipated effect location and damage quotes, in order to settle their evacuation of residents and crucial facilities and to get ready for any casualties and eventually recovery efforts.

Take a look at the current Twitter thread with highlights from todays statement:.

#FictionalEvent ☄ Three more months of observations from around the globe have actually fine-tuned our understanding of asteroid # 2019PDCs orbit, which now has a 10% opportunity of striking Earth.

Thursday 2 May: Day four.
3 September 2024.
In action to hypothetical asteroid # 2019PDC– set to impact Denver, Colorado– three kinetic impactor objectives were sent out to crash into the space rock and nudge its orbit far from Earth. The objectives effectively deflected its primary body, however, a 50-80-metre fragment is presently still certain to clash with Earth. The new impact website is unknown, however the Eastern United States and Atlantic ocean are presently at risk.

Wednesday 1 May: Day three.
30 December 2021:.
It was chosen that a reconnaissance mission was needed to comprehend more about imaginary asteroid 2019 PDCs size, orbit and composition. More than 2 years after the asteroid was discovered, the reconnaissance objective has now found is that the 200-m asteroid is on a certain clash with Denver, Colorado in the United States of America.
Here is the 3rd (imaginary) press release:.

Tuesday 30 April: Day two.
29 July 2019.
The second news release on imaginary asteroid 2019PDC is out, and its not looking great. Four months after asteroid # 2019PDC is identified, observations now show the possibility of Earth effect has actually increased to 1 in 10.

” If asteroid # 2019PDC is headed directly at Earth, we wont know for sure up until the year 2020. How do we make a decision? What do we do now?”.
Additional updates will be provided every day of the Planetary Defense Conference– remain tuned!

As soon as informed on the most recent information, participants to the Planetary Defense Conference split into groups to go over the recommendations they will put to the “Asteroid 2019 PDC Mitigation Task Force”.
