00:00Europe's space agency has been collaborating with China for over 25 years

00:05and now there's a project to collaborate on a rocket which will probe space weather.

00:12Philippe Escoubert is Project Scientist with the European Space Agency.

00:17Certainly we have started this collaboration with China since a very long time.

00:21In the cluster's time we started already to collaborate.

00:25At that time cluster was a European mission

00:29but Chinese got interested and we started to collaborate by exchange of students.

00:34Then a few years later the Chinese Academy of Science proposed a double star mission

00:40where we collaborate and they led the program.

00:43And now with mine it's about 50-50% on each of the missions.

00:48So 50% ISA, 50% CAS.

00:50For the future we have to see.

00:53Nothing is decided yet but certainly we have a long collaboration with China.

00:58What is the objective of this SMILE collaboration?

01:03SMILE is a collaboration between the European Space Agency and the Chinese Academy of Science

01:09and we want to make the invisible visible.

01:13We want to study in particular the Sun-Earth relation and the solar storm.

01:18How the solar storm and the Sun which are big eruption of plasma

01:23sometime directed towards Earth and how do they interact with Earth.

01:28So what we look at is this big cloud when they arrive around the Earth

01:33they make a compression and a big change in the Earth's magnetic field.

01:38And with SMILE we will measure this interaction in x-ray.

01:43And this is the first time we do that in x-ray.

01:46It's like when you do a body scan in x-ray to see the bones in your body.

01:52We do the same with the metrosphere and we have this region of interaction

01:57between the Sun and the Earth appearing and being bright in x-ray.

02:02How does solar weather affect us here on Earth?

02:06And what are some of the questions that you are hoping to answer?

02:10I mean they can affect in various ways.

02:13The main thing which are a bit critical when we have this big aura and big currents

02:19flowing in the Earth's magnetic field, this could affect power lines.

02:24Big power lines that give current to many countries

02:28where they can be affected by this current in the metrosphere

02:32and sometimes they can be disrupted.

02:34You can have also effect on GPS satellites which may be less precise

02:39because of this Sun-Earth interaction.

02:42And there are various also other effects that space weather is trying to study.

02:46SMALI is not a space weather mission but we study the science which is behind space weather

02:51to better understand space weather.
