People launch a rocket. They launch it from Kazakhstan. It is a Russian rocket. It carries two probes into space.
The probes are European. This is the ExoMars mission. The European Space Agency organises it.
The probes are going to Mars. That takes seven months. When they are close to Mars, the probes separate. One probe goes down to Mars. The other one moves around the planet. It gets information about the atmosphere.
Difficult words: launch (to go up), probe (a spacecraft which gets information about something; there are no people on the spacecraft), separate (to go apart).

People launched a rocket from the Baikonur Cosmodrome in Kazakhstan. The Russian rocket carried up two robotic probes which will travel to Mars. This is the European Space Agency’s ExoMars mission.
If all goes to plan, the journey to Mars should take seven months – the probes will reach the planet in October. When they get close to the Red Planet, they will separate. One probe will land on Mars and the other will orbit around the planet.
It will collect information about the atmosphere. Scientists are especially interested in the methane gas there because this is a sign of life.
Difficult words: launch (to go up), probe (an unmanned spacecraft which collects information), separate (to go apart), orbit (to move in a circle).

Baikonur Cosmodrome, Kazakhstan. A Proton rocket stands ready for launch. Inside, two robotic probes destined for the Red Planet. Together they make up the European Space Agency’s ExoMars mission.
The rocket will launch at 3:31 p.m. local time on Monday or 9:31 a.m. GMT. Around 10 hours later, the rocket will separate and the probes will continue their journey towards Mars. If all goes to plan, that journey should take seven months, reaching the planet in October.
Three days out from the edge of the Martian atmosphere, the two probes will separate. An entry, descent and landing demonstrator module known as Schiaparelli will drop towards the surface. There, it will test technology for future missions and make environmental observations for a short period of time before its batteries die.
The Trace Gas Orbiter, meanwhile, will enter the planet’s orbit, spending a year making manoeuvres to lower its altitude to 400 kilometres. By December 2017, it will be ready to begin analysing the make-up of the Martian atmosphere. In particular, scientists want to understand the presence of methane gas, a sign that life may once have existed on the Red Planet.
Difficult words: Proton (a Russian rocket type), launch (to go up), probe (an unmanned spacecraft which collects information), destined (going to a place), GMT (Greenwich Mean Time), entry (entering the atmosphere of Mars), descent (to fall), demonstrator (a thing that shows how things work), altitude (the height of the object).
