TITLE: Asteroid probe snaps rare images of Martian Moon


March 13, 2025 3:29 PM

By Agence France-Press


Paris -
On the way to investigate the scene of a historic asteroid collision, a European spacecraft swung by Mars and captured rare images of the red planet's mysterious small moon Deimos, the European Space Agency said Thursday.

Europe's HERA mission is aiming to find out how much of an impact a NASA spacecraft made when it deliberately smashed into an asteroid in 2022 in the first test of our planetary defenses.

But HERA will not reach the asteroid - which is 11 million kilometers from Earth in the asteroid belt between Mars and Jupiter - until late 2026.

On the long voyage there, the spacecraft swung around Mars on Wednesday.

The spacecraft used the planet's gravity to get a "kick" that also changed its direction and saved fuel, mission analyst Pablo Munoz told a press conference.

For an hour, HERA flew as close as 5,600 kilometers from the Martian surface, at a speed of 33,480 kilometers an hour.

It used the opportunity to test some of its scientific instruments, snapping around 600 pictures, including rare ones of Deimos.

The lumpy, 12.5-kilometer-wide moon is the smaller and less well-known of the two moons of Mars.

Exactly how Deimos and the bigger Phobos were formed remains a matter of debate.

Some scientists believe they were once asteroids that were captured in the gravity of Mars, while others thinkthey could have been shot from a massive impact on the surface.

The new images add "another piece of the puzzle" to efforts to determine their origin, Marcel Popescu of the Astronomical Institute of the Romanian Academy said.

There are hopes that data from HERA's "HyperScout" and thermal infrared imagers which observe colors beyond the limits of the human eye - will shed light on this mystery by discovering more about the moon's composition.

Those infrared imagers are why the red planet appears blue in some of the photos.

Next, HERA will turn its focus back to asteroid Dimorphos. When NASA's DART mission smashed into Dimorphos in 2022, it shortened the 160-meter-wide asteroid's orbit around its big brother Didymos by 33 minutes.

Although Dimorphos itself posed no threat to Earth, HERA intends to discover whether this technique could be an effective way for Earth to defend itself against possibly existence-threatening asteroids in the future.

Space agencies have been working to ramp up Earth's planetary defences, monitoring for potential threats so they can be dealt with as soon as possible.

Earlier this year, a newly discovered asteroid capable of destroying a city was briefly given a more than 3% chance of hitting Earth in 2032.

However further observations sent the chances of a direct hit back down to nearly zero.

Richard Moissl, head of the ESA's planetary defense office, said that asteroid, 2024 YR, followed a pattern that will become more common.

As we get better at scanning the skies, "we will discover asteroids at a higher rate," he said.

The ESA is developing a secondary planetary defense mission to observe the 350-meter-wide asteroid Apophis, which will fly just 32,000 kilometers from Earth on April 13, 2029.

If approved by the ESA's ministerial council, the Ramses mission will launch in 2028, reaching the asteroid two months before it approaches Earth.

    Nesta questão, o foco está na compreensão de um trecho do texto em inglês, especificamente a frase 'The spacecraft used the planet's gravity to get a 'kick'.'

    Essa expressão quer dizer que a espaçonave utilizou a gravidade do planeta para obter um impulso ou uma aceleração. Esse tipo de manobra é conhecida como assistência gravitacional, onde a gravidade de um corpo celeste é aproveitada para aumentar a velocidade ou mudar a trajetória de uma nave espacial, economizando combustível.

    Agora vamos analisar as opções:

    a) 'Is being used' indica uma ação no presente contínuo, que não condiz com o tempo passado narrado no texto.

    b) 'Was used' está no passado, concordando com o tempo da ação descrita no texto. Essa opção significa que a gravidade do planeta foi usada pela espaçonave para obter um impulso, o que é o mesmo sentido do trecho original.

    c) e d) estão invertendo os sujeitos e objetos, estão incorretas porque a nave não está 'chutando' a gravidade, nem o planeta está chutando a gravidade da nave (que sequer existe).

    e) 'was used for the spacecraft to get a 'kick'' está errada por causa da preposição 'for', que não é adequada nesse contexto e torna a frase estranha.

    Portanto, a única opção correta é a letra b.

    Gabarito: b
