The two types of aerospace engineers include aeronautical engineers (They work with aircraft that stay within the earth's atmosphere such as airplanes and helicopters.) and astronautical engineers (They work with aircraft that operate outside of the earth's atmosphere such as rockets, satellites, and other and spacecraft.) A degree in aerospace engineering should cover them both. As for the future, it is hard to say.  According to the US Occupational Outlook Handbook, employment for aerospace engineers is expected to grow about 5% from 2010 to 2012 which is a little slower than average.
