問題詳情:
NASA-s New Horizons probe(宇宙探測器)flew by Pluto(冥王星)this morning,
sending back history's first up-close looks at the vast freezing-cold world. Closest
approach came at 7:49 a.m. EDT. To celebrate, NASA gave out the latest photo of
Pluto. It showed a reddish world with an amazing heart-shaped feature on its surface.
After today's close encounter, all the nine solar system's traditionally recognized
planets have now been visited by a spaceship-a huge project begun in 1962 when NASA's
Mariner 2 probe flew past Venus, a planet in the solar system. More than l,200
scientists, NASA guests and important persons, including 200 reporters, watched the
flyby live at New Horizons' mission control center.
That close encounter has been a long time coming. The$723 million New Horizons
mission launched in January 2006 but began taking shape in *. "New Horizons is'a
capstone mission'," Glen Fountain, mission project manager told Space, com. "It is the
first completion of the observations of our solar system. It-s giving us a new idea about
how we human beings fit into the universe."
New Horizons "faced a crazy number of challenges," Stern, a driving force behind
New Horizons said, "So many people stuck with this for so long. They got knocked
down; they stood up. They got knocked down again; they stood up again.”
In a coincidence, today's close approach falls on the 50th anniversary of the first flyby
of Mars, another planet, which was completed by NASA-s Mariner 4 spaceship.
There are no longer nine officially recognized planets, of course. The International
Astronomical Union regarded Pluto as “a dwarf planet" in 2006 in a decision that remains
controversial(有爭議的)today.
h statement is TRUE according to the passage?
A. Ideas still vary in the identity of Pluto.
B. Only scientists could watch the flyby live.
C. Mars is the first planet visited by a spaceship.
D. New Horizons mission aimed to observe the solar system.
Fountain may probably agree that _____________________.
A. it is the most difficult to land on Pluto in the solar system
B. New Horizons mission is a long and troublesome project
C. their strong determination leads to the successful flyby
D. people are likely to find new ways to fit into space
h is the best title for the passage?
A.A New Horizons Probe B. NASA's Huge Project
C. Pluto,a Controversial Planet D. A Close Approach to Pluto
