Every now and then, news about Mars become the talk of the town, especially those that talk about new discoveries on the Red Planet and updates on NASA's planetary missions. Just recently, word about discoveries of "alien" life forms and bodies of water on Mars have fed on people's curiosities.

But what, really, is on Mars? Why are NASA's scientists so interested in searching and exploring the Red Planet? Do alien life forms exist there? The space agency's latest findngs show that ithe chance of having "life forms" on the Red Planet is now higher.

Daily Caller sat down with Dr. Penelope Boston, NASA's Astrobiology Institute director, to get an idea on the probability that microbes exist in other parts of the solar system. Dr. Boston pointed to Mars as the planet where extraterrestrial life can most likely exist.

Dr. Boston said her team has been working in a "holistic way" to find life on Mars. However, limited resources made the task too demanding for them. That's why NASA now considers launching a space station above Mars' orbit an option in 2028, the report said. Dr. Boston said the mission will be "most cost-effective" as questions about life on the Red Planet will be answered in a " sensible and systematic fashion".

Last February, Mirror.co.uk reported footage of alien life on Mars captured by conspiracy theorists. They think that they discovered a "military-style base" of aliens on the Red Planet. The video footage was uploaded to YouTube by Secure Team 10, showing a "large base that looks like a military installation".

The video divided opinion upon its release. Some viewers weren't convinced, saying that it's only a "blurry image of a rock," but others said "the truth cannot be hidden" - pertaining to NASA's plan to hide the "aliens" from people.

Still, there's no concrete proof of life on Mars, but with the use of highly-sophisticated equipment nowadays and plans of NASA's mission to the Red Planet in the coming years, it won't be surprised if "life forms" or "aliens" do exist not only within our solar system, but in other parts of the cosmos, too.
