Living Jewish on Mars
You're probably asking yourself, "are there enough passerbys on Mars who I can get to shake Lulav?", or "will I be able to put a menorah on my Martian rover for Chanukah?". Unfortunately, life on Mars will indeed be different from on Earth, but that doesn't mean the quality of Chabad-ness needs to go down. Early on there may not be as many people as there are in Times Square who can shake Lulav, but in the long term there might be. Until then, there is much other work to be done.
