d. None of the above

ANSWER: Sentinel IB, Microscope
 
Europe is set to launch two satellites on Friday with very important missions: one will track environmental damage to Earth, while the other will test a mainstay of physics theory.
  • Setting off on a Russian Soyuz rocket will be Sentinel-1B with its Earth surveillance radar, and Microscope, a French-built orbiter seeking to poke a hole in Einstein's theory of general relativity.
  • They will be hoisted from Europe's launch pad in Kourou, French Guiana, at 2102 GMT on April 22.
  • The Soyuz will also boost into orbit three so-called "CubeSats", tiny orbiters built by European science students.
