SVT's Lilla Aktuellt has spoken to the Wandt family before father Marcus's departure.

For the past two weeks, he has been in quarantine before the trip.

- We are ready to go and it will be great fun.

I haven't gotten nervous yet, but we'll see, says Marcus Wandt.

The children have been able to meet him twice in the past few days, but only from a distance.

And once in space, they will be able to talk to each other during two video calls.

- I'm proud of dad.

It feels surreal, soon he will go up into space, says Benjamin Wandt.
