After ChandraYaan mission Isro become very popular among youngsters. I have received lots of email regarding this.
Isro ( Indian space research organization ) does come for campus placements to Indian Institute of Technology , so if you crack IIT and opt aerospace engineering from there , you can wait for Placement to come.
For others Isro has well updated Isro website which has complete information and pdf files about job opportunities.
