NASA, FEMA Hold Asteroid Emergency Planning Exercise

NASA, FEMA Hold Asteroid Emergency Planning Exercise
NASA/JPL press release Nov. 5, 2016

What would we do if we discovered a large asteroid on course to impact
Earth? While highly unlikely, that was the high-consequence scenario
discussed by attendees at an Oct. 25 NASA-FEMA tabletop exercise in El
Segundo, California.

The third in a series of exercises hosted jointly by NASA and FEMA --
the Federal Emergency Management Agency -- the simulation was designed
to strengthen the collaboration between the two agencies, which have
Administration direction to lead the U.S. response. "It's not a matter
of if -- but when -- we will deal with such a situation," said Thomas
Zurbuchen, Associate Administrator for NASA's Science Mission
Directorate in Washington. "But unlike any other time in our history, we
now have the ability to respond to an impact threat through continued
observations, predictions, response planning and mitigation."

The exercise provided a forum for the planetary science community to
show how it would collect, analyze and share data about a hypothetical
asteroid predicted to impact Earth. Emergency managers discussed how
that data would be used to consider some of the unique challenges an
asteroid impact would present-for preparedness, response and public warning.

"It is critical to exercise these kinds of low-probability but
high-consequence disaster scenarios," FEMA Administrator Craig Fugate
said. "By working through our emergency response plans now, we will be
better prepared if and when we need to respond to such an event."

Exercise attendees included representatives from NASA, FEMA, NASA's Jet
Propulsion Laboratory, the Department of Energy's National Laboratories,
the U.S. Air Force, and the California Governor's Office of Emergency
Services.

The exercise simulated a possible impact four years from now -- a
fictitious asteroid imagined to have been discovered this fall with a 2
percent probability of impact with Earth on Sept. 20, 2020. The
simulated asteroid was initially estimated to be between 300 and 800
feet (100 and 250 meters) in size, with a possibility of making impact
anywhere along a long swath of Earth, including a narrow band of area
that crossed the entire United States.

In the fictitious scenario, observers continued to track the asteroid
for three months using ground-based telescope observations, and the
probability of impact climbed to 65 percent. Then the next observations
had to wait until four months later, due to the asteroid's position
relative to the sun. Once observations could resume in May of 2017, the
impact probability jumped to 100 percent. By November of 2017, it was
simulated that the predicted impact would occur somewhere in a narrow
band across Southern California or just off the coast in the Pacific Ocean.

While mounting a deflection mission to move the asteroid off its
collision course had been simulated in previous tabletop exercises, this
particular exercise was designed so that the time to impact was too
short for a deflection mission to be feasible -- to pose a great future
challenge to emergency managers faced with a mass evacuation of the
metropolitan Los Angeles area.

Scientists from JPL, Lawrence Livermore National Laboratory, Sandia
National Laboratories, and The Aerospace Corporation presented predicted
impact footprint models, population displacement estimates, information
on infrastructure that would be affected, as well as other data that
could realistically be known at various points throughout the exercise
scenario.

"The high degree of initial uncertainty coupled with the relatively long
impact warning time made this scenario unique and especially challenging
for emergency managers," said FEMA National Response Coordination Branch
Chief Leviticus A. Lewis. "It's quite different from preparing for an
event with a much shorter timeline, such as a hurricane."

Attendees considered ways to provide accurate, timely and useful
information to the public, while also addressing how to refute rumors
and false information that could emerge in the years leading up to the
hypothetical impact.

"These exercises are invaluable for those of us in the asteroid science
community responsible for engaging with FEMA on this natural hazard,"
said NASA Planetary Defense Officer Lindley Johnson. "We receive
valuable feedback from emergency managers at these exercises about what
information is critical for their decision making, and we take that into
account when we exercise how we would provide information to FEMA about
a predicted impact."

NASA provides expert input to FEMA about the asteroid impact hazard
through the Planetary Defense Coordination Office
<https://www.nasa.gov/planetarydefense>. NASA and FEMA will continue to
conduct asteroid impact exercises and intend to expand participation in
future exercises to include additional representatives from local and
state emergency management agencies and the private sector.

New asteroid discovery 2016 EF195: 15,000 miles from Earth's surface

reported by  meteordetective

Things seem to be picking-up rapidly!

NASA NEOP has just posted details of asteroid 2016 EF195 which made its close-approach at just 15,558 miles from Earth's surface on 11-Mar-2016 at 03Z52.

2016 EF195 is estimated to be 20m - 50m in diameter (based on magnitude) and travelling at 10km/s  or 6.25 mi/s.  It's close-approach brought it beneath geo-stationary satellite altitude of ~22,236 miles.  It was not detected until 4 days after its close-approach.

It is the 4,881st asteroid (within 0.5 AU) to be discovered in the first two weeks of March 2016 (NASA period "E") and the 34th asteroid discovery of 2016 period "E" to approach within 10LD or less.

2016 EF195 is the 2nd asteroid within a month (the other was 2016 DY30) to make its close-approach below geo-stationary satellite altitude.

Keep your cameras ready and your eyes on the skies (when it's safe to do so).

New asteroid made close-approach less than 5,000 miles from Earth's surface

New asteroid made close-approach less than 5,000 miles from Earth's surface
reported by  meteordetective

NASA have published data of a very close-approach which occurred on Feb-25 at 19:49Z (note that the asteroid was not discovered until the following day).

The asteroid in question is 2016 DY30 (the 774th <0.5 AU asteroid to be discovered since March 01 2016).

Its nominal (expected) close-approach distance was just 4933.546 miles from Earth's surface.  Although small (estimated to be 2-5m in diameter), it was travelling at just over 17km/s (relative to Earth) at the time of its close-approach.

2016 DY30 entered NASA's all-time close-approaches table at position #5.  It is the 6th asteroid, this year, which has found its way on to the 'top 100' table. There were 13 new entries in this 'top 100' table last year (2015) and 12 entries during 2014.

8 asteroids have made / will make their close-approach of less than 1LD (average distance from Earth to the Moon) during the current +/- 30 days period.  2016 DY30 was the only one of these which was (well) below geo-stationary altitude of 22,236 miles.

Asteroid news: NASA's update on 2013 TX68

Asteroid news: NASA's update on 2013 TX68
reported by  meteordetective
Link to article which was updated on Thu 25-Feb-2016 at 14:40 Pacific Time (22:40Z) and was originally posted on Tue 02-Feb-2016.

NASA have refined their "earlier flyby and distance predictions, reconfirming that the asteroid poses no threat to Earth."

But, the 'plot' thickens, as NASA has additionally "..identified an extremely remote chance that this small asteroid could impact on Sep. 28, 2017, with odds of no more than 1-in-250-million. Flybys in 2046 and 2097 have an even lower probability of impact."

I thought I'd investigate further and used Telnet to 'talk' to JPL's "Horizons" system.  However, as you can see (from the copy/paste below), there is no close-approach listed for 2017.  To be clear and specific, I instructed Horizons to show me all the known approaches from 01-Jan-2000 to 01-Jan-2200.

If you access the asteroid's entry in JPL's SBDB, you'll see the following Close-Approach dates & times listed, which barely correspond to the Telnet session results (above).

2016-Mar-08 00:06, 2056-Sep-18 13:29, 2071-Sep-30 14:02, 2074-Feb-17 05:44, 2084-Oct-20 19:33, 2086-Oct-16 07:11, 2089-Feb-07 09:03, 2089-Mar-14 21:35.

Is something out of sync?

I'd initially intended to comment on the wide variance of 2013 TX68's potential close-approach distances (all relative to Earth's surface), which are remarkable and summarised below:

Nominal (the expected or 'should be' distance): 13.06 LD = 3,099,296.455 miles
Minimum: 0.08LD = 15,282.762 miles
Maxium: 45.09LD = 10,714,428.346 miles

(For reference, 1 LD --aka 1 Lunar Distance-- is equivalent to 382,500 kilometers / 239,062.5 miles (NASA)).

The difference between minimum and maximum values is 7,615,132 miles or 8.19% of the distance from Earth to the Sun...or also equivalent to 3,185.42% the distance from Earth to the Moon....which is a rather large value.

To add a further variable in to this situation, MPC have assigned 2013 TX68 a condition code of 8 for  its orbit uncertainty (10=highly uncertain and 0 = "good"), which is due to the fact that 2013 TX68 was only tracked for 3 days when it was initially discovered/observed - before it was 'lost' again.

Let me make myself perfectly clear:  I'm not suggesting 2013 TX68 will hit Earth, inferring it or stirring-up 'fear-porn'.  I'm just a little perplexed by the apparent of confusion --regarding when it will make its close-approaches to Earth-- and mentioning that there's a very wide margin of 'error' between the distances NASA are reporting for its 08-March-2016 close-approach.

Stay tuned!

  Asteroid 2003 SD220 will safely fly past Earth on Dec. 24 at a distance of 6.8 million miles (11 million kilometers). Scientists at NASA's Jet Propulsion Laboratory in Pasadena, California, have generated the highest-resolution images to date of this asteroid using the Deep Space Network's 230-foot (70-meter) antenna at Goldstone, California. The radar images were acquired between Dec. 17 and Dec. 22, when the distance to this near-Earth object (NEO) was narrowing from 7.3 million miles (12 million kilometers) to almost the flyby distance. ... morehttp://www.jpl.nasa.gov/news/news.php?release=2015-387&rn=news.xml&rst=4807

Meteoroids Associated with the Halloween Asteroid '2015 TB145' Could Put on a Spooky Meteor Shower
Posted to YouTube by nemesis maturity 3,401 views

All eyes are on the "Great Pumpkin" asteroid ahead of its Halloween close approach. Asteroid 2015 TB145 still poses no threat to Earth, but it does continue to deliver some surprises. The latest observations reveal meteoroids associated with the asteroid are unlikely to hit Earth, but, if anything changes, they could put on a show for some skywatchers, particularly in Asia.

The 1,300-foot-wide asteroid 2015 TB145 was discovered less than three weeks ago and will be zoom past Earth at a completely safe distance of approximately 310,000 miles. Without any fear of impact, the asteroid provides an ample opportunity for scientific research, according to NASA. The latest observations indicate asteroid 2015 TB145 may be a dormant comet complete with meteoroids.http://www.ibtimes.com/halloween-aste...

Posted to YouTube by nemesis maturity 222 views
Published on Jan 26, 2015
  BRIGHT ASTEROID FLYBY--TONIGHT: A mountain-sized space rock is approaching Earth for a harmless but eye-catching close encounter on Monday night, Jan. 26-27. The incoming asteroid, named 2004 BL86, will be just 740,000 miles away (3.1 times farther from us than the Moon) and visible in ordinary binoculars.
  At closest approach, sunlight reflected from the surface of 2004 BL86 will make it glow like a 9th magnitude star. Amateur astronomers with even small backyard telescopes can see it zipping among the stars of the constellation Cancer.

ALERT: "Small Mountain" Asteroid 2004 BL86 Very Close Encounter Jan. 26
Asteroids sweep by Earth all the time but one is particularly attracting attention, given its size and how close it will be flying by the planet.
Called 2004 BL86, the asteroid is estimated to be about 650 m - 950 m in size.
Coming in as close as 745,000 miles from Earth, equivalent to around three times the distance of the moon to the planet, 2004 BL86 will be making the closest flyby for an asteroid this large.
The asteroid is expected to be observable to amateur astronomers with small telescopes and strong binoculars.
"Monday, January 26 will be the closest asteroid 2004 BL86 will get to Earth for at least the next 200 years. And while it poses no threat to Earth for the foreseeable future, it's a relatively close approach by a relatively large asteroid, so it provides us a unique opportunity to observe and learn more," said Don Yeomans, former Near Earth Object Program Office manager from the Jet Propulsion Laboratory in California. Yeomans retired last Jan. 9.

Scientists have calculated that 2014 UR116 asteroid will fly in dangerous proximity to Earth every three years. If it collides with the planet the energy of the explosion could be a thousand times greater than the impact of the Chelyabinsk meteorite.  Vladimir Lipunov, a leading scientist on the team which discovered the asteroid this October, says the scientists now know its orbit and its period which is 3 years, but they cannot say precisely when the asteroid will approach the Earth....

Posted to YouTube by nemesis maturity 25 views
Published 04SEP2014
This week provides another reminder of the reality of that threat, not that Earth’s history doesn’t already provide plenty of warnings.

The record of history, as written in the many impact craters on Earth and the moon, demonstrate that it is just a matter of time before astronomers discover a near Earth object (NEO) headed toward a collision with Earth.

The asteroid 2014 rc will pass below the Earth and the geosynchronous ring of communications and weather satellites orbiting 35,890 km (22,300 miles) above our planet's surface.

Asteroid 2014 RC was initially discovered on the night of 31 August by the Catalina Sky Survey near Tucson AZ, and independently detected the next night by the Pan-STARRS 1 telescope, located on the summit of Haleakala on Maui, Hawaii. Both reported their observations to the Minor Planet Center in Cambridge, MA. Additional follow-up observations by the Catalina Sky Survey and the University of Hawaii 88-inch on Mauna Kea confirmed the orbit of 2014 RC. From its brightness, astronomers estimate that the asteroid is about 20 meters (60 feet) in size.

While 2014 RC will not impact the Earth, its orbit will bring it back to the Earth's neighborhood in the future. Its future motion will be closely monitored but no future threatening Earth encounters have been identified. http://neo.jpl.nasa.gov/news/news184....
