And what if they fail and divert it to the earth
 Quoting: Anonymous Coward 41173011


Ye.

That could make it WORSE.
 Quoting: Anonymous Coward 80659637

Not going to happen. The maximum delta V it could impart would be utterly incapable of diverting it to earth. It won't even break orbit from Didymos.
 Quoting: Astromut


How much of an effect would 20+ Chinese rockets have on stopping or diverting a large asteroid? Is it even possible with current technology?

What are your thoughts about repurposing communications satelites to effect this?

Thanks Astromut
 Quoting: StellaBlue


I don't think repurposing communications satellites will do much, they don't have enough fuel to get very far from their geostationary orbits. If you use dozens of China's largest rocket, yeah you could probably impart much more delta-V than the DART mission could.

It's a great test, actually. The weak gravity of Didymos means it's relatively easy to alter the smaller asteroid's orbit in a way that is measurable to verify the exact delta-V imparted, and it provides a test on a real but very small asteroid of just how effective a kinetic impactor will be. Will it even hold together or break up? If it breaks up, a kinetic impactor may not be a good option in case of a large threatening rock. Breaking up a real impact threat would lead to smaller asteroids potentially hitting earth regardless.

The Double Asteroid Redirection Test (DART) mission is directed by NASA to the Johns Hopkins Applied Physics Laboratory (APL) with support from several NASA centers: the Jet Propulsion Laboratory (JPL), Goddard Space Flight Center (GSFC), Johnson Space Center (JSC), Glenn Research Center (GRC), and Langley Research Center (LaRC).

DART is a planetary defense-driven test of technologies for preventing an impact of Earth by a hazardous asteroid. DART will be the first demonstration of the kinetic impactor technique to change the motion of an asteroid in space. The DART mission is in Phase C, led by APL and managed under NASA’s Solar System Exploration Program at Marshall Space Flight Center for NASA’s Planetary Defense Coordination Office and the Science Mission Directorate’s Planetary Science Division at NASA Headquarters in Washington, DC.

The binary near-Earth asteroid (65803) Didymos is the target for the DART demonstration. While the Didymos primary body is approximately 780 meters across, its secondary body (or “moonlet”) is about 160-meters in size, which is more typical of the size of asteroids that could pose the most likely significant threat to Earth. The Didymos binary is being intensely observed using telescopes on Earth to precisely measure its properties before DART arrives.

Ok yes NASA definitely doesn't always tell the whole truth.

But of course there are tons out there lurking, that we don't know about. NASA readily admits they are not aware of anywhere near all of the debris lurking about.

We have a very tiny view of space, we can't see most of it.

That's the point of these tests. To see if they could divert one that they actually DO see.

11 And the name of the star is called "wormwood": therefore the third part of the waters became wormwood, and many men died of the waters, because they were made bitter.
