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.

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.

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.

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?

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

In August of 2014, the European Space Agency Rosetta probe reached the comet 67/P. This mission allowed for the collection of a great deal of data about comets. In fact, in this episode, a comet will be fashioned out of fairly common ingredients in a normal kitchen. That's pretty exciting.

Ugo and Nora are very much in love, and that's where this story starts. The story of this two-episode mini-series is set in the port city of Trieste in northern Italy. Sposami means "marry me."

The exasperated lawyer comes up with a plan for the dog who happens to be named Uno (one). As they are taking care of this, they each get a phone call and have to hurry off.

Neither Ugo nor Nora has any desire to take Aunt Clo up on her offer, but then reality kicks in.

Aunt Clo shows Ugo and Nora around the shop and house and leaves after giving them a few rules to follow. They run off to the attorney to make sure they can go ahead with their separation.

Nora and Ugo are living in close quarters, and there is a list of eight rules nailed to the back of the door that they are already arguing about.

Nora is having trouble forgetting what Ugo did to her but gets down to work, or tries to. Uno comes back.

As Ugo walks Uno, he goes by his old bookshop. He meets someone he knows, which sets off a little chain of events, giving him a new outlook on things. Meanwhile, Nora is up to her neck in paperwork.

Aunt Clo calls to make sure things are OK with Nora and Ugo, but has a favor to ask. A future bride comes to try on her dress and it looks like she might be getting cold feet.

Ugo has good intentions, but he unwittingly puts the business in a tricky position. Nora rallies but feels Ugo is never around when she needs him.
