0 a small spacecraft, with no one travelling in it, sent into space to make measurements and send back information to scientists on earth --
He has taken part in several high profile space probe missions and is an expert on space debris, space dust and impacts.
The best way to illustrate it is by describing the launching and directive of this space probe.
This is a direct medical consequence of the space probe.
It is suggested that this exosphere must contain many other molecular species, which should be detectable, by a future space probe.
It should be relatively easy to detect life on the surface of planets even from a fly-by space probe.
This on the spot investigation is obviously impossible if radio signals are sent out instead of a space probe.
If viruses or spores had been found on those heavenly bodies already visited by space probes, the case for extraterrestrial life would be strengthened, but they have not.
It was the first demonstration that artificially-created signals could penetrate the ionosphere, opening the possibility of radio communications beyond the earth for space probes and human explorers.
