The key point about aerosols is that they float about in the air for hours, meaning you could theoretically catch the virus despite having no contact with an infected person if you walk into a train carriage where an infected person was standing several hours ago, for example. The bacterium that causes tuberculosis and the viruses that cause measles and chickenpox are all commonly spread through aerosols. Last spring, most of the scientific community was sceptical that airborne transmission played any meaningful role in the spread of Covid.
India did take this into account and mostly minimized debris:According to Jonathan McDowell, an astrophysicist at Harvard Smithsonian Center for Astrophysics, some debris might persist for a year, but most should burn up in the atmosphere within several weeks. Brian Weeden of Secure World Foundation agreed, but warned about the possibility of some fragments getting boosted to higher orbits. US Air Force Space Command said that it was tracking 270 pieces of debris from the test, although as of 26 September only 125 objects have been catalogued. A Dutch Space Situational Awareness consultant Marco Langbroek disputed DRDO claim that the test was responsible. He said that the intercept was not “head on”, which would have minimized debris ejection to higher altitudes, but was instead conducted at an upwards angle. He added that most of the debris would be cleared within days, but some might last a year or two.But I do agree that any debris added is bad.Compared to the India test, though, the China one was much worse:This event was the second largest creation of space debris in history after Project West Ford, with more than 2,000 pieces of trackable size (golf ball size and larger) officially catalogued in the immediate aftermath, and an estimated 150,000 debris particles.
