Tomorrow on “Two Way Street,” we’re talking to astronaut Scott Kelly, who holds the American record for most consecutive days in space.

President Trump has formally told NASA to send U.S. astronauts back to the moon.

"The directive I'm signing today will refocus America's space program on human exploration and discovery," he said.

Standing at the president's side as he signed "Space Policy Directive 1" on Monday was Apollo 17 astronaut Harrison Schmitt, one of the last two humans to ever walk on the moon, in a mission that took place 45 years ago this week.

Georgia Tech is not just looking at interstellar space, it’s also traveling through it. Georgia Tech student Michael Staab is a spacecraft flight controller for NASA. He piloted the Cassini spacecraft, which traveled around Saturn and nearby moons collecting data.

The terms “alt-right,” “far-right,” and “radical right” get thrown around a lot these days. But there’s actually very little research on what those terms mean and who the people are identifying with them. Cas Mudde, Professor in the Department of International Affairs at UGA, is looking to change that. His new book is “The Far-Right in America.” He joins us to analyze the movement and its many subsets.

South Korea faces a chronic dirty air problem that makes it one of the most polluted countries in the world. It's common to hear that neighboring China is to blame, but a joint study by NASA and the Korean government has found there's a lot South Korea can do on its own to cut the smog.

President Trump's pick for the next leader of NASA is a fighter pilot who wants Americans to return to the moon but doesn't believe that humans are causing climate change.

The Pentagon is considering pulling out of a deal it made with thousands of noncitizen recruits with specialized skills: Join the military and we'll put you on the fast track to citizenship.

The proposal to dismantle the program would cancel enlistment contracts for many of the foreign-born recruits, leaving about 1,000 of them without legal protection from deportation.

NASA announced last month it will recruit a team of Georgia Tech researchers for a new project. The team, called REVEALS, will study radiation on other planets and build radiation proof space suits. What can this technology do for us in space exploration?

We ask the team leader, Thomas Orlando, a Director in the Center for Space Technology and Research at Georgia Tech.
