What about the fact that the B 612 Foundation, for several hundred million dollars received from sponsors, several years ago ordered to the Ball Aerospace company the corresponding space telescope, which received name Sentinel, which was completely manufactured? It was practically ready to be...

This is not surprising given my comments on the articles in Nature: https://www.nature.com/articles/s41586-023-05805-2 https://www.nature.com/articles/s41586-023-05878-z

It will be respectfully noted that taking into account additional observational data casts doubt on the declared change in the Dimorphos`s orbital period. In particular, data obtained using the ATLAS-STH telescope (see the second part of the video, around the 50th second: View...

In general, I agree with you. But the answers to your questions require computer simulations for the «many-body problem». This can be done by colleagues who, unlike me, have access to all routine observational data. As for using data of the same type of eclipses or occultations, it seems that it...

Familiarity with the articles recently published in Nature and arXiv, which discuss the results of the DART mission, reveals the following. Firstly, the key data interpretations and the validity of the conclusions are not convincing without taking into account the results of direct ground-based...

So far, the question about the "success of NASA's DART mission" remains open. At least until the publication of three articles in Nature, which were announced as "submitted" in references to reports at the expected conference https://www.hou.usra.edu/meetings/lpsc2023/technical_program/#20230314...

Dear colleague, if you do not know which methods of disclosure regarding scientific or technological results are evidence-based and credible (see my first post), do not agree with the experimentally established internal structure of NEAs (which excludes the use of any "pulse" approaches and...

I agree with your assessment of the gravitractor method efficiency . For the sake of brevity, I have given only one of its shortcomings, which has manifested itself recently, thanks to an understanding of the NEAs internal structure. To illustrate it, one can do (or imagine) the following simple...

It seems that avoiding collisions with the help of an extremely risky and contrary to international law nuclear explosion, alas, remains popular ... However, more optimal options are needed, in addition to sci-fi (for example, laser with the PRACTICAL impossibility of cooling powerful lasers in...

Dear colleague, unfortunately your statements “you argue that the rubble pile is not monolithic, then seem to argue as if it is, except for the ejecta. And you argue that the heavy ejecta does not rotate with the main body" are wrong. First, looseness (rubble pile) for NEAs is currently well...

These are additional details needed to understand. Please see this video RIGHT after 50th second ignoring the relatively far-flung and expanding "cloud". It shows that Dimorphos`s image has approximately doubled in size, which leads to an estimate of the photometric center displacement by...

Regarding the «DART mission having been declared a resounding success». Briefings, emotional interviews, impressive photos, PR-type publications - all this can be important for discussions and conclusions in politics, but not in science. Before the appearance of publications in peer-reviewed...
