Although space travel exposes astronauts to forms of radiation that are uncommon on Earth, and that are linked to cancers and heart problems, a U.S. study suggests this doesn’t significantly shorten their lives.

When SpaceX launches Japanese billionaire Yusaku Maezawa and his eight traveling companions for a trip around the Moon in 2023, the company will be undertaking an unprecedented step toward the future of civilian space flight. But with being the first to attempt this feat comes a number of technical and safety challenges that less ambitious expeditions, like Blue Origin's treks to the Karman Line, won't have to face. So, just how will SpaceX ensure that its first trip to the Moon doesn't turn into a real-life Gravity?

New research from scientists at the University of Nevada, Las Vegas (UNLV) shows that the cancer risk for astronauts undertaking long-term missions to Mars or any other destination beyond Earth’s magnetic field is actually twice what we previously thought.

The cancer risk for a human mission to Mars has effectively doubled following a UNLV study predicting a dramatic increase in the disease for astronauts traveling to the red planet or on long-term missions outside the protection of Earth's magnetic field.

We welcomed Dr. Francis (Frank) Cucinotta to the show to discuss the radiation risks for astronauts going to Mars and even living on Mars. Please note that Dr. Cucinotta has provided us with four .pdf papers you might want to review. These papers have been uploaded to the archives for this show.

Since the year 2000, humanity has maintained a continuous presence in space aboard the International Space Station (ISS).

Four new names will soon be added to the periodic table as scientists have put forth their recommendations for the names of elements 113, 115, 117 and 118. The names proposed for the new elements are in honor of Japan, Moscow, Tennessee, and a Russian scientist.

Question: What would taking a leisurely trip to Mars do to an astronaut’s brain? Answer: Nothing good.

People have long imbued gold with mystical powers of immortality. Ancient alchemists ate it in search of longevity.
