(5)Having just departed the reddish-looking dwarf planet Pluto, NASA’s New Horizons spacecraft is en route to another object that is similarly colored, officials at the US space agency announced earlier this week.
(6)In fact, 2014 MU69—one of 11 Kuiper Belt objects that the probe is scheduled to study over the next several years—is "even redder than Pluto" but "not quite as red as Mars" , according to New Horizons team member Amanda Zangari.
Zangari presented her team’s findings at the AAS Division for Planetary Sciences and European Planetary Science Congress on Tuesday.(7)They determined its color using observations collected by the Hubble Space Telescope, Space, com said, and while the exact size of the estimated 13-25 mile(21-40 km)wide object is not yet determined, it is now the tiniest Kuiper Belt object to have its color determined in this way, the SwRI-led team revealed.
Knowing that 2014 MU69 is reddish in color is more than a novelty, Zangari explained during the conference—it "tells us the type of Kuiper Belt object 2014 MU69". This newfound data "confirms" that when New Horizons completes a flyby of the object on January 1, 2019, it "will be looking at one of the ancient building blocks of the planets".
Questions 5 to 7 are based on the news report you have just heard.
5. What is the news report mainly about?
6. What do we know about the color of 2014 MU69?
7. How did the New Horizons determine the color of 2014 MU69?
