This segment talks about the difference between an asteroid and a comet. Important work is being done with the Hera and Dart missions to study how to deviate an asteroid, thus avoiding possible great damage to our beloved planet

This segment is all about so-called "Near-Earth Objects," called "NEOs" for short. They are comets, asteroids, metors and man-made objects, as well. What have they done in the past, and what might they do in the future?

Astronaut Luca Parmitano talks to us from the Columbus European Space Laboratory. He explains why tadpoles can help us learn a lot about the weightless conditions of outer space.

A simple experiment with a bicycle pump shows us how rocket launchers work. Even though rockets were invented for war and for fireworks, they are also used for peaceful purposes.

Observing what happens when the air comes out of a balloon will help us understand how the launcher of a spacecraft works. An electrical propulsion engineer from ESA explains about different kinds of propulsion used in space exploration.

To reach outer space, the force of gravity has to be overcome, and that requires a certain "escape" velocity. That's where launchers come in.

One way to tell if there might be life on another planet is through light. Special telescopes, by way of prisms, analyze and break down the light from distant galaxies into parts. Luca Parmitano, an astronaut of the European Space Agency, speaks to us from the Columbus International Space Station.

Luisella Giulicchi, the system manager for the ESA Copernicus Sentinel six mission, explains what an exoplanet is. Two young researchers do a simple experiment to show us how infrared rays work.

Luisella Giulicchi, manager of the European Space Agency ESA, answers questions about light, infrared rays, and lightyears.

What is light? We use it every day, but where does it actually come from? The host suggests doing a little experiment. See if you can follow the instructions in Italian and try it yourself.

The Columbus laboratory is the first permanent European research facility in space. There, astronauts carry out experiments and applications in space science, Earth observation and technology. Columbus offers European scientists full access to a weightless environment that cannot possibly be duplicated on Earth.

Some simple experiments with various materials help us understand what goes into planning the construction of a spacecraft. And then we wonder how we would go about making a planet inhabitable to humans.

3D printing is going to be a huge factor in conducting the safe exploration of the Moon and Mars. Experiments carried out on the "nearby" Moon will be crucial for later trips to Mars, a much more complicated, long-term enterprise.

The International Space Station has the goal of developing and testing technologies for space exploration that are capable of keeping a crew alive on long-term missions in lunar and Martian orbits. To do this, preliminary work is being done on the Gateway platform: a space station beyond Earth's orbit.

It was a tough 72 days, but, as the title suggests, the family recovered, luckily. They think back on their time in isolation and what it felt like to come out the other side. Their story even made it into a local newspaper.
