On this episode of "This Week in Space," we're seeing busy times at the Kennedy Space Center! Axiom Space is set for the first launch of an all-private crew to the International Space Station from Pad 39A, the Space Launch System is testing over on Pad 39B, and SpaceX's Crew 4 mission is set to depart Pad 39A soon thereafter. Axiom's all-private flight to the ISS comes just two years after the first SpaceX crew launch to the station—and Axiom is also working on modules for the first all-private space station. Also, Hubble spies the most distant star ever, the Mars Helicopter aces another record-setting flight, and Apollo astronaut Tom Stafford tutors NASA on cooperation in space with Russia.

NASA rolled its massive megarocket, the SLS, to the pad last week. It's the first moon rocket to emerge from the VAB in 50 years. What's next? Also, the Webb telescope beats expectations, another lunar lander is coming, and Blue Origin rides again!

Rod Pyle and Tariq Malik take a look at space junk—what is it, where did it come from, and what can be done about it. The sheer amount of debris orbiting Earth is a serious threat to ongoing missions and must be addressed, or we may find ourselves permanently earthbound. Also, the SLS rolls out, astronauts and cosmonauts stay friends, and the Mars helicopter flies on. All on this episode of This Week in Space.

On this episode of This Week in Space, we'll tell you everything you need to know to fly your own rockets (mostly responsibly)--it's fun, it's safe, and it's a great hobby for a family to do together. Also, Virgin Orbit to launch from Old Blighty, tugboats headed for orbit, and astronaut Scott Kelly, who has flown on the Russian Soyuz, returns his Russian-awarded spaceflight medal in protest. Join us!

We talk atomic rockets and nuclear power sources (RTGs) in space. In "The Martian," Watney used a surplus Radioisotope Thermoelectric Generator to heat his rover but real spacecraft, like the Galileo and Cassini probes to Jupiter and Saturn, have used nuclear isotopes to power their vast arrays of instruments. And, the amazing Voyager spacecraft still talk to us from beyond the solar system powered by a small plutonium pellet.
