It is difficult to let your partner leave you forever, but it was true love of Dr. Leila Zucker's husband who sent her an email last spring pointing to a one-way trip to Mars. Zucker was thrilled after receiving the email from her husband about Mars One, a non-profit organization aiming at sending four people to the Red Planet in 2024 and more groups later on.

Zucker was one of 200,000 applicants who applied to participate in the mission. But now, she is among 705 candidates who made it through successive interviews and tests. The group was reduced from 1,058 people after some prospective astronauts had to be dropped because of personal and medical reasons.

Mars One selection committee will interview all of the remaining candidates now. However, only four best suitable candidates will be given the green signal to be the part of the mission. But it must not be forgotten that the trip is not meant to take candidates to Mars on a picnic, but it is to set up a platform for human colonization in Mars. Due to technological and financial limitations, it would probably never be possible for Mars One Astronauts to come back home.

Mars One CEO Bas Lansdorp has said that the company is trying its best to raise enough funds to make the mission a success. Zucker, 46, an emergency medicine physician in Washington, said that it is very less likely for the company to organize a trip to Mars at all. However, if it happens, she will be on board for sure.

Zucker and her husband are married for 21 years, but they do not have any kid from their marriage. She said that if she goes to Mars then she will offer a divorce to her husband but she will never take off her wedding ring.

She said, "Both of us are space enthusiasts. Humanity needs to expand off Earth if we expect the human race to succeed in any way beyond just basic survival".
