The apogee/ perigee of 2019-006A, the object likely shot down, was 260- 282 km, pretty low. Some of that debris could be quite a bit higher, but most of it will be lower, and all of it will have a new perigee/ apogee in that range, which will likely be shrinking quickly. It is expected that it will be similar to the debris cloud from USA-193 (Operation Burnt ...

At this time, it is not yet known. There are some 250 objects observed, but it takes time to catalog them all. The object destroyed was most likely MICROSAT-R (TLE catalog number 43947, which is in a 294 x 265 km orbit at 96 degrees inclination. Due to the nature of the event, it's likely some of the objects have apogees well above ISS orbit. At this ...

If you listen patiently to the first video in the answer to your question What did India's recently tested ASAT vehicle really look like?, you'll hear that this was a one-off. It took 2 years of R & D plus integration to produce a single vehicle. This means that India does not, yet, have the capability to produce this vehicle in a series, which argues ...

At what altitude range is the resulting debris field? Update: CNN: India anti-satellite missile test a 'terrible thing,' NASA chief says India's anti-satellite missile test created at least 400 pieces of orbital debris, the head of NASA says -- placing the International Space Station (ISS) and its astronauts at risk. NASA administrator Jim Bridenstine said ...

I'll just follow up a bit on the collision. Per tweet and tweet and answer and answer and post: launch 5:40 UT (27 March 2019) MICROSAT-r 43947, 2019-006A over Abdul Kalam Island 5:42 UT I've put a recent TLE into Skyfield and we can see that the satellite was moving north from the equator towards Abdul Kalam Island, India. According to the image in India'...

You need 2 items to evade a missile: a means of detecting an incoming missile. There are specialized satellites that are used to monitor ICBM launches, IDK how well the technology scales down. enough maneuvering capability to evade a missile - while the missile is maneuvering to follow you. ASAT missiles can already maneuver to make sure they hit their ...

The following is not based on any authoritative information. Note that the goal is to hit the target. To do that, you want to guide onto a constant bearing, decreasing range situation. If the target is sitting at a constant point on the image plane, you're going to hit it. If it's moving in any direction and you don't take corrective action, that motion ...

Thanks to @Ohsin's comment I have plotted the propagated orbits of 57 tracked debris objects with published TLEs as well as the TLE for (whatever is left of) the original spacecraft and the original rocket body, as well as for the ISS. You can see that most of the debris still has a low periapsis where it was created, but a lot of it has aopapsis of 1000 to ...
