November 2021 competition: a logic puzzle

Five entrepreneurs are planning missions to the solar system with the companies they've set up, to set off in consecutive years (the planets are listed in order of distance from the sun - or just remember that My Very Educated Mother Just Served Us Noodles).

Given the information below, see if you can work out who is going where, and when:

  1. Beryl is going further out from the sun than Green Shoots are, and setting off later than them.
  2. Bill's company is going one planet further out from the sun than Galactic Greyhounds.
  3. Neither Bob nor Bharat run companies with animals in their names.
  4. The mission to Uranus leaves 3 years before Bea's company Verging in Space sets off.
  5. Space Z aren't going to Mars, aren't run by Bharat and aren't setting off in an even-numbered year.
  6. Bea will set off before Bob, and travel further.
