    NASA Aims at an Asteroid Holding Clues to the Solar System´s Roots
                                                       (Kenneth Chang, Sept. 5, 2016)

For the next two years, NASA’s latest robotic spacecraft will be chasing down an asteroid near Earth in the hopes of scooping up some of the most primordial bits of the solar system.
 The premise of the mission for the spacecraft, Osiris-Rex, is simple: Fly to an asteroid, grab some of the rock and bring it back to Earth, where scientists will study some of the pristine ingredients that went into the making of the solar system, including possibly the building blocks of life.
 “What was that beginning organic material like?” James L. Green, the director of NASA’s planetary science division, said in an interview. “That’s what’s really exciting about this. This is what we want.”
 “It’s 500 meters or so in size, about the height of the Empire State Building,” Dr. Green said. Discovered in 1999, Bennu is a carbon-rich, almost black asteroid. Data from NASA’s Spitzer Space Telescope and radar measurements by ground-based radio telescopes suggest it is a “rubble pile” with pebbles about half an inch wide on the surface. 
 “It’s a time capsule from the earliest stages of solar system formation,” said Dante Lauretta, a professor of planetary science and cosmochemistry at the University of Arizona who is the mission’s principal investigator.
 Osiris-Rex will survey Bennu for more than a year to select the site where it will grab the sample of rock. In July 2020, the spacecraft, about the size of a sport utility vehicle, is to slowly descend and bounce off the surface like a pogo stick at a gentle pace of a quartermile per hour. A sampling head, which looks like an automobile air filter, will shoot a burst of nitrogen to kick up dirt and small rocks during the three to five seconds it is in contact with the surface. 
 The goal is to collect at least a couple of ounces of material and possibly as much as 4.4 pounds. The spacecraft carries enough nitrogen to attempt to extract material three times if necessary.
 After departing Bennu in 2021, Osiris-Rex will pass by Earth in September 2023, dropping off a capsule with the samples that will land via parachute in a Utah desert.
 Studying this asteroid could also come in handy if it is ever on a collision course with Earth. With about a 14-month orbit, Bennu passes fairly close once every six years. 
In 2035, it will make a particularly close approach, passing within the orbit of the moon, and Earth will give enough of a gravitational kick that astronomers cannot precisely predict where the asteroid will go after that.(...)

" With about a 14-month orbit, Bennu passes fairly close once every six years. " 


Se você comparar com as demais corretas, isto é, 01, 02 e 04, verá claramente que esta sentença transmite a ideia, no contexto do texto, de frequência ou ocorrência cíclica, mas não de algo projetado ou planejado para ocorrer no futuro, como ocorre nos demais casos:


01 - "For the next two years, NASA’s latest robotic spacecraft WILL be chasing down an asteroid near Earth in the hopes of scooping up some of the most primordial bits of the solar system."


02  e 04- "Osiris-Rex WILL survey Bennu for more than a year to select the site where it will grab the sample of rock. In July 2020, the spacecraft, about the size of a sport utility vehicle, is to slowly descend and bounce off the surface like a pogo stick at a gentle pace of a quartermile per hour. "
