Kometa se u vreme udara nalazi na 134 miliona km od Zemlje, sto znaci da mora postojati zakasnjenje jer signal putuje brzinom svetlosti
(300 000km/s).
Evo ti odgovor zasto NASA nemoze prenositi live video

Q: I gather we'll see the collision in full-motion video (televised) because the event will be near enough. At what point is full-motion video no longer possible, i.e. at what distance from Earth?
We will not be able to observe the impact in "full motion video" (ie., at a rate of 30 frames/sec) because of data rate limitations both in the imaging cameras and in the data link from the spacecraft to Earth. The cameras are designed to make accurate scientific measurements, not primarily to produce video. As such, the imaging detectors are read out relatively slowly in order to keep the noise levels low, and the data are encoded to 14 bits to make the most accurate measurements possible. At their full frame format (1024x1024 pixels), the cameras will output only one frame every 1.7s. At impact and for the following few seconds, we plan to use subframe imaging modes (64x64 pixels in the Medium Resolution Instrument and 256x256 pixels in the High Resolution Instrument). With these formats, the cameras can produce frames at rates of about 20/sec for the MRI and 5/s for the HRI. So we will be able to reconstruct the impact itself with pretty good time resolution. Even if the cameras could produce frames at 30/sec, the data link to Earth at the range of the comet at impact would not allow the data to be returned to Earth fast enough to support full-motion video in real time. The maximum data rate that we expect to use given the spacecraft telecommunications system capabilities and the receiving capabilities of the Deep Space Network stations on Earth is about 300,000 bits/s, which is about 200 times slower than needed for full-motion digital video. The data link could support full-motion video only at ranges less than about 10 million km.

Zasto bi nas vanzemaljci tako zbrisali? Mislio sam da smo im hrana. I sta ce njima razorena planeta koje ce biti u postnuklearnoj zimi sledecih nekoliko stoleca.
Zasto uvek u svemu vidite neke skrivene agende, urote, skrivanja. To vise nije opreznost i svesnot i postaje simptomaticno.
