The longstanding mystery of Mars' moons—and the mission that could solve it

The two small moons of Mars, Phobos (about 22km in diameter) and Deimos (about 13km in diameter), have been puzzling scientists for decades, with their origin remaining a matter of debate. Some have proposed that they may be made up of residual debris produced from a planet or large asteroid smashing into the surface of Mars (#TeamImpact).
An opposing hypothesis (#TeamCapture), however, suggests the moons are asteroids that were captured by Mars's gravitational pull and were trapped in orbit.
To solve the mystery, we'll need material from the moons' surfaces for analytical analyses on Earth. Luckily, the Japan Aerospace Exploration Agency (Jaxa) will launch a mission, named "Martian Moon eXploration" (MMX), to Phobos and Deimos in September 2024. The mission will be carried by a newly designed rocket, the H-3, which is still under development.
The spacecraft is expected to reach Martian orbit in 2025, after which it will orbit Phobos and finally collect material from its surface before returning to Earth by 2029.
This will make it the next in a series of recent missions bringing material from space back to Earth, following on from Jaxa's successful mission to asteroid Ryugu (Hayabusa2), as well as Nasa's Osiris-Rex mission to asteroid Bennu and the Chinese Space Agency's Chang'e 5 mission to the Moon.
Was going to space a good idea?

In 1963, six years after the first satellite was launched, editors from the Encyclopedia Britannica posed a question to five eminent thinkers of the day: "Has man's conquest of space increased or diminished his stature?" The respondents were philosopher Hannah Arendt, writer Aldous Huxley, theologian Paul Tillich, nuclear scientist Harrison Brown and historian Herbert J. Muller.
Sixty years later, as the rush to space accelerates, what can we learn from these 20th-century luminaries writing at the dawn of the space age?
The state of space 60 years on
Much has happened since. Spacecraft have landed on planets, moons, comets, and asteroids across the solar system. The two Voyager deep space probes, launched in 1977, are in interstellar space.
A handful of people are living in two Earth-orbiting space stations. Humans are getting ready to return to the moon after more than 50 years, this time to establish a permanent base and mine the deep ice lakes at the south pole.
There were only 57 satellites in Earth orbit in 1963. Now there are around 10,000, with tens of thousands more planned.
