Hi Clay - I expect that impactor detection and deflection will become important issues to the states of Florida and Alabama. NASA launches its rockets from...
Your last sentence indicates that you may have misread my message; I am sure that the Russian scientists remember the events...or at least have it historically...
Good morning and happy new year. Is there a authoritative work on the frequency of impacts and a standard way of assessing threat. Someone has said a Tunguska...
Hi Terry - That "someone" was most likely me. I began reporting on NASA and NEOs in 1997, and began limited historical research at that time. This work...
Interesting. In 2000 I published a taxonomy on conflict prevention - that study path led me to the realization that man's future presents many known potential...

... 200,000 million years? Wow! That's older than the age of the universe. The folks working on the Hubble constant must have gotten it wrong again. Has...

Some months ago we had some lengthy debates about the accuracy of the UCAC3 catalogue. I have just completed an assessment of asteroidal occultations observed...
Remember that in asteroidal occultations we are working at the full precision of the catalogues. The observation requires us to relate the position of the...

Greetings MPML, We are attempting to schedule time at Goldstone for radar observations of 2010 AL30 early on January 13. The pointing uncertainties are...
... Unlikely to be artificial, it's orbit doesn't resemble any useful spacecraft trajectory, and its encounter velocity with the Earth is not unusually low,...

Since this object is almost on an impact trajectory, this is a great example of how much warning time we have for an object with H = 27.0 Andrea The Catalina...
Indeed.....visitors frequently ask me if I worry about the NEOs that I measure; my response: "I don't worry about those that we keep up with....I am more...
And also a great example of most objects coming from the solar or anti-solar (opposition) direction. This one is only 15 deg off of the exact anti-solar...
Richard, Cheers and good to hear of this! Is there a place for us newcomers to find the ephemeris for this object? Those of us that can do video astrometry...
Hello all, here is my page with local data but also a video animation of 2010 AL30 near Earth fly by. http://www.dangl.at/2010/2010_al30/2010_al30.htm ...
Does anyone have access to any CCD images of 2008 TC3, taken during its swan-dive into Sudan? I am interested in studying the refinement of the uncertainty...
I managed to get a few images of 2010 AL30 tonight which measured as follows: K10A30L C2010 01 12.27905 07 39 05.14 +09 31 49.8 17.0 718 ...
