Asteroid impact drill uncovered: Fictitious press releases reveal government’s April 29 doomsday role-play

A 2019 asteroid deflection exercise just so happened to begin on April 29... there's that date again!

(INTELLIHUB) — A high-level government spawned role-player event uncovered by Intellihub reveals a top-down drill in which national interagency working for groups and select participants in 2019 acted out a fictitious scenario that’s based around a hypothetical asteroid impact and how various nations of the earth would plant to mitigate the damage.

The 2019 PDC Hypothetical Asteroid Impact Scenario was presented for the first time at the 6th International Academy of Astronautics Planetary Defense Conference which took place between the dates of April 29 – May 3, 2019. (There’s that April 29 date again)

A similar hypothetical NEO/Earth impact event scenario had been presented at previous conferences but none as detailed as this. This was a whole new animal per se.

For the first time, a rather detailed working plan was submitted in front of 281 conference attendees which included people from all walks of life–space agencies, government agencies, news agencies, non-profits, universities, etc, etc. All cream of the crop.

The 5-day planetary defense exercise was based on a single track sequential link method of wargaming “meaning that all presentations were sequential, and all were presented in a plenary session,” as the original conference paperwork points out. “The goal was that all attendees would receive the latest information on all aspects of planetary defense, including what we know about asteroids and comets; how a threatening object might be deflected or otherwise mitigated; designs of deflection missions and campaigns; and consequences if an asteroid were to strike our planet and how a disaster might be managed.”

The 2019 PDC Hypothetical Asteroid Impact Scenario

A hypothetical asteroid impact scenario will be presented at the 2019 IAA Planetary Defense Conference (PDC), to be held in College Park, Maryland, USA, April 29 – May 3, 2019. Although this scenario is realistic in many ways, it is completely fictional and does NOT describe an actual potential asteroid impact. The scenario begins as follows:

  • An asteroid is discovered on March 26, 2019, at magnitude 21.1, and confirmed the following day. It is assigned the designation “2019 PDC” by the Minor Planet Center. (To reinforce the fact that this is not a real asteroid, we are using three letters in the designation, something that would never be done for an actual asteroid.)
  • Initial calculations indicate that the orbit of 2019 PDC approaches well within 0.05 au of the Earth’s orbit. (The unit “au” stands for “astronomical unit”, which is the mean distance of the Earth from the Sun, 149,597,870.7 km, or 92,955,807 miles.) Since the initial estimate of the asteroid’s absolute (intrinsic) magnitude H is 21.7, it qualifies as a Potentially Hazardous Asteroid (PHA).
  • The asteroid’s orbit is eccentric, extending from a distance of 0.89 au from the Sun at its closest point to 2.94 au at its farthest point in the middle of the main asteroid belt. Its orbital period is 971 days (2.66 years), and its orbital plane is inclined 18 degrees to the Earth’s orbital plane.
  • The day after 2019 PDC is discovered, JPL’s Sentry impact monitoring system, as well as ESA’s similar CLOMON system, both identify several future dates when this asteroid could potentially impact the Earth. Both systems agree that the most likely potential impact occurs on April 29, 2027 – over eight years away – but the probability of that impact is very low, about 1 chance in 50,000. With only two days of tracking this object, no more definitive statement can be made.
  • When first detected, the asteroid is about 0.38 au (57 million kilometers or 35 million miles) from Earth, approaching our planet at about 14 km/s (8.5 mi/s or 31,000 mph), and slowly getting brighter. 2019 PDC is observed extensively for a few weeks after discovery, and as the observational dataset grows, the impact probability for 2027 increases. Three weeks after discovery, when observations pause during full moon, the impact probability has risen to nearly 0.4 percent, or about 1 chance in 250. The asteroid continues to brighten somewhat as it approaches, but it reaches a peak brightness of only 20.3 at the end of April.
  • Very little is known about the asteroid’s physical properties. Based on the apparent visual magnitude, its absolute (intrinsic) magnitude is estimated to be about H = 21.7 +/- 0.4. Since its albedo (reflectivity) is unknown, however, the asteroid’s mean size could be anywhere from roughly 100 meters to over 300 meters.
  • 2019 PDC approaches the Earth for well over a month after discovery, and it reaches its closest point of about 0.13 au on May 13. Unfortunately, the asteroid is too far away to be detected by radar, and it is not expected to pass close to the Earth again, until 2027.
  • Astronomers continue to track the asteroid almost every night, and the impact probability for 2027 continues to rise. As of April 29, 2019, the first day of the 2019 Planetary Defense Conference, the probability of impact has climbed to about 1%. The rest of the scenario will be played out at the conference.

Here are additional details on what we know about 2019 PDC on the first day of the conference:

  • The following diagram shows the orbits of 2019 PDC and Earth, along with their positions when the asteroid was discovered on March 26, 2019, and the point at which the orbits intersect. The asteroid makes just over 3 orbits of the Sun between discovery and the potential impact.
Orbit of Asteroid 2019 PDC
  • The following diagram zooms in on the intersection point of the orbits of 2019 PDC and the Earth, and shows the current uncertainty in the predicted position of the asteroid when the Earth crosses through the intersection point on April 29, 2027. The uncertainty region is several times longer than the diameter of the Moon’s orbit. As the asteroid is observed over subsequent months in 2019, its orbit will become better defined and the uncertainty region in 2027 will shrink in size.
Position uncertainty of asteroid 2019 PDC on April 29, 2027 (based on observations through April 29, 2019)
  • The asteroid’s uncertainty region at the time of the potential impact is much longer than the diameter of the Earth, but its width is only about 70 kilometers (45 miles). The intersection of the uncertainty region with the Earth creates a so-called “risk corridor” across the surface of the Earth. The corridor wraps more than halfway around the globe, spanning from the Hawaii on the western end, across the U.S. and Atlantic Ocean, and all the way to central and southern Africa on the eastern end. The red dots on the following two Google Earth images are Monte Carlo points that trace the risk corridor:
Risk corridor of 2019 PDC – image 1
Risk corridor of 2019 PDC – image 2

A Google Earth kml file for these impact points is available here.

  • A table of the impact circumstances of impact points along the central axis of this corridor can be found here. The columns of this table are as follows:
    • xi & zeta are the Opik b-plane coordinates of the trajectory, in kilometers
    • Lat & ELon are the latitude and East longitude of the impact point, in degrees
    • Vel is the velocity at impact, in km/s
    • Az & El are the azimuth (measured eastwards from North) and elevation of the incoming velocity vector, in degrees
    • Time is the UTC time of the impact on the impact date, 2027-Apr-29.
  • The red dots in the risk corridor are Monte Carlo points, which are all essentially equally likely. While there are gaps between the points shown here, the risk corridor is really a continuum, with the impact probability proportional to the average density of the points. Note that the points become more widely spaced towards the ends of the corridor because the asteroid enters at shallower and shallower elevation angles.
  • The asteroid should remain continuously observable over the remaining months of 2019, although it gets difficult to observe in late May, when it moves as close as 50 deg from the Sun. It will also slowly fade as it recedes from the Earth, requiring fairly large (2-meter-class) telescopes to see it. The asteroid continues to fade during late 2019, reaching 23rd magnitude in October, 24th magnitude in November, and 25th magnitude in December. During that time, observers will require very large aperture telescopes such as the 4- and 8-meter class facilities of CFHT, Keck, Gemini, Subaru, VLT, etc., to track the object. By February 2020, the asteroid will approach 27th magnitude and become essentially unobservable for almost a year, until late 2020.
  • A special version of the JPL orbit viewer has been created for this object and can be accessed here.
  • The orbit for the central point of the risk corridor for 2019 PDC has been loaded into JPL’s HORIZONS system, and can be accessed via the name “2019 PDC”. HORIZONS can be accessed with this object preloaded via this web-interface here.
  • For those familiar with the SPICE Toolkit software, an SPK file for this same orbit has been created and is available here:ftp://ssd.jpl.nasa.gov/pub/xfr/2019-PDC/2019_PDC-merged-DE431.bspThe SPK file is consistent with and contains additional DE431 planetary ephemeris information over the time-span 1998-Jan-01 though impact on 2027-Apr-29, permitting retrieval of object state vectors at any arbitrary instant within that timespan.
  • The orbit for the central point of the risk corridor for 2019 PDC has been loaded into the JPL/Aerospace Corp. NEO Deflection App. This on-line tool allows users to study the velocity change (delta-v) required to deflect the 2019 PDC trajectory away from the Earth, as a function of deflection time. Specific amounts of impulsive velocity change can be applied at specific times before impact and the resulting deflection in the impact b-plane is shown. The App can also be configured to calculate kinetic impactor spacecraft trajectories, as well as the spacecraft masses that can be launched onto those trajectories by various launch vehicles. The App calculates the delta-v applied to the asteroid when the kinetic impactor hits it, and determines the Opik b-plane coordinates, xi and zeta, of the deflected trajectory. Using these coordinates, you can roughly determine the impact point of the deflected trajectory by interpolating in the table of impact circumstances given above. A complete description of the app is available here.The 2017 PDC trajectory is also loaded into the App along with trajectories of many other simulated Earth impactors.

A 5-day barrage of fake news reports discovered in exercise documents

Fake daily press briefings from the 2019 exercise reveal a slow government rollout of information pertaining to such an event. It makes me wonder if they would even warn the general public ahead of any impending disaster in which they had foreknowledge.

Check out the following scripted press releases from the drill labeled “NOT A REAL-WORLD EVENT.”

The exercise potential impact zone map looks similar to the Johns Hopkins University COVID-19 case map. Keep in mind that the Johns Hopkins University is also heavily involved with NASA’s DART program in which they can control the trajectory of near-earth-earth-bound objects using several methods which include but are not limited to kinetic impaction and nuclear deflection.

It is also important to make clear that on April 29, 2020, NEO asteroid 1998 OR2 safely passed the earth.
