Why is the SpaceIL Lunar Lander doing a one-way trip? Is that a common project to do nowadays, to send landers to Mars and the Moon without returning them?

    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.

$begingroup$

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.
