Astronomers and Cosmologists are not Rocket Scientists; they are Space Scientists, and most Rocket Scientists are Chartered Engineers or their equivalents. Let me also add, that the engineering courses in the western world for chartered engineers and their equivalents, for which I have experience of, for over 50 years, including at Russell Group universities & at ex-Polytechnic universities, etc., at both undergraduate and postgraduate levels; do not, in general, stifle the imagination of the engineer; whereas this may not be true of some of the equivalent courses in some of the other parts of the world. Thus, do not worry  too much, about the number of engineers that are being produced by the  universities of some of the other parts of the World! The imagination of Chartered Engineers or their equivalents, helped humankind to set foot on the Moon, and remember what  Einstein said about imagination; he said, "Imagination is more important than knowledge, because knowledge is limited, but imagination encircles the world". Moreover, the Chartered Engineers and their equivalents, who helped put humankind on our Moon, did not get a Nobel Prize for this feat, because they do not have Nobel Prizes in Engineering! In case any artisan engineers read my blog, and they are fearful of their job prospects, and they have not got enough money to enroll for a full-time degree in chartered engineering, I suggest to them that they may consider enrolling for a foundation degree in engineering; while still working for a living. They can enroll for a part-time foundation degree in engineering at their local college or their local ex-Polytechnic University for a relatively small fee. For many of these courses, they need only attend the educational establishment for about 1/2 a day per week; during term time, for a few years. After they have got their foundation degree, they can then enroll for a one year full-time engineering degree; which may lead them to becoming a Chartered Engineer and hopefully, a more secure career! In my opinion the combined qualifications of an artisan engineer, together with the qualifications of that of a Chartered Engineer, are a "Winner"; Planet Earth needs this combination badly!
