In short:
Japan has launched a space rocket to study one of Mars's moons for the first time.
asserted
Japan → launch → time
The five-year mission hopes to better understand the origin of water and organic matter on Mars.
What's next?
At the end of the mission, the capsule containing moon samples is expected to land in South Australia.
asserted
capsule → hop → Australia
Japan has launched an international space mission to collect sand and rock from one of Mars's moons for the first time.
asserted
Japan → launch → time
When the sample is brought back to Earth, it will land in Australia.
asserted
it → bring → Australia
The mission, led by the Japan Aerospace Exploration Agency (JAXA), will largely focus on Phobos, a Martian moon that has never been explored, to study how Mars and its moons formed.
asserted
Mars → lead → Phobos
A rocket carrying the Martian Moons eXploration (MMX) spacecraft was launched this morning from Japan's Tanegashima Space Centre.
asserted
rocket → carry → Centre
The MMX spacecraft will spend a year travelling to the Martian sphere, where it is set to arrive in 2027.
asserted
it → spend → 2027
It will then enter a quasi-satellite orbit around the moon, Phobos.
asserted
It → enter → moon
It is hoped the mission will provide new insights about the origin of water and organic materials on Mars and will be a stepping stone for potential human exploration in the future.
asserted
mission → hop → future
Once it has arrived, the MMX spacecraft will conduct observations of the moon and attempt two "soft landings".
asserted
spacecraft → arrive → landings
That is when a rover will be sent to the surface of Phobos to collect at least 10 grams of sand, at a depth of about 2 centimetres.
asserted
rover → send → centimetres
"One reason why collecting samples from Phobos is extremely difficult is that its gravity is very weak," Yaji Kentaro from the MMX project team said.
asserted
Kentaro → collect → team
"Because the surface gravity is so low, there were concerns that the rover might tip over upon landing."
To try to counteract that, the "landing legs" on the rover have been designed with special features to ensure a stable landing.
uncertain
legs → be → landing
The MMX spacecraft will also be taking photographs.
asserted
spacecraft → take → photographs
"I'm really looking forward to seeing what kind of images MMX will send back as it gets closer and closer to Mars, and as it captures views of both Mars and Phobos — our final destination."
asserted
it → look → Mars
After completing the sample collections on Phobos, the spacecraft will then observe Mars's second moon, Deimos, before beginning its year-long journey back to Earth.
asserted
spacecraft → complete → Earth
What could we learn from the 'potato-shaped' moon?
uncertain
we → learn → moon
The surface of Mars is described as a cold desert, and the planet has a thin atmosphere, but scientists believe it once had a similar environment to Earth.
There are traces of water on Mars and suggestions that life could have once developed there.
uncertain
life → describe → Mars
"While Earth is home to many living organisms, including humans like us, the question remains where the water and organic matter necessary for life came from," Mr Yaji said.
asserted
Yaji → live → life
"It is hoped that the answer to this question may be hidden within the samples."
uncertain
answer → hop → samples
The MMX project team said Phobos, the "potato-shaped" moon orbiting Mars, had not undergone the same geologic evolution of planets and so should have preserved evidence of the early development of Mars.
asserted
Phobos → say → Mars
That could provide information about the processes required for the formation of a habitable planet.
uncertain
That → provide → planet
There are conflicting theories about how Mars's moons formed.
asserted
moons → be → ?
The first is that there was a huge collision with Mars; the second is that they started as asteroids and were pulled into Mars's gravity.
asserted
they → be → gravity
The MMX project hopes its observations and analysis of the sample it collects will help identify where the moons originated from, which could help explain the formation of the solar system and the movement of material through it.
uncertain
which → hop → it
Mars's strong gravity means landing and collecting samples from the planet itself would be difficult, but the mission is seen as a stepping stone for further exploration.
asserted
mission → mean → exploration
Australia will play a role
asserted
Australia → play → role
Australia's ambassador to Japan, Andrew Shearer, was among several international dignitaries who travelled to the remote Tanegashima island to watch the rocket launch.
asserted
who → travel → launch
France and Germany's ambassadors were also there, along with the deputy ambassador from the United States and representatives from other space agencies, including NASA.
asserted
ambassadors → include → NASA
Australia will play an essential role in the final stages of the mission.
asserted
Australia → play → mission
After the spacecraft travels back from the Martian system, a re-entry capsule containing the sand and rock samples from the Moon will separate and re-enter the atmosphere.
The capsule is expected to land in Woomera, in remote South Australia, where the sand sample will be retrieved.
asserted
sample → travel → Australia
