  Maybe because of the smaller budget that drove to have a lighter payload which did not allow for extra fuel?

  This is a "show" mission more than a scientific mission, and a successful landing and walkabout it sufficient to make it a spectacular success for a first time deep space mission for this agency. Returning to Earth is just an opportunity to fail, whereas success may bring interest in a follow-on mission.

  It is very common for Mars landers not to return. In fact, it is ubiquitous.

  One way trips are and have always been the norm in space exploration. The few sample return missions (mentioned by @Hobbes) are very much the exceptions.

A one-way trip is much simpler and much cheaper than a return mission.

• a return mission is more complicated because it has to do more


• a return mission is much heavier (because of the extra systems, and the fuel needed for the return capsule) which means it needs a bigger launcher which is more expensive

We have had no sample return missions from any planet. There were a few from the Moon (Apollo and Luna), and a few from objects like asteroids and comets (e.g. Hayabusa).

The SpaceIL mission is a small, low-cost mission done as a technology demonstration. A return mission would have cost 10x more.
