Welcome to Spotlight 1. I’m Dianna Anderson.
Voice 2
And I’m Liz Waid. Spotlight uses a special English method of broadcasting. It is easier for people to understand, no matter where in the world they live.
Voice 1
It was early in the morning on August 6th, 2012. A room full of scientists were gathered together. They were watching their computers screens and waiting for news. Just after twelve in the morning, the scientists began cheering. They were celebrating. They had done it! They had landed a large piece of scientific equipment – or a rover - on the planet 2 Mars 3.
Voice 2
The scientists named this Mars Rover, “Curiosity 4.” Curiosity is a desire to learn or know about something. And this is exactly what the rover “Curiosity” represents. Curiosity will explore the surface of Mars. It will study its rocks. It will take clear, high quality pictures of the planet. And it will help scientists learn more than ever about Mars. Today’s Spotlight is on the Mars Rover, “Curiosity.”
Voice 1
People have long been curious about the planet Mars. Interest in the possibility of life on Mars has filled our imaginations. For over a century, people have written hundreds of stories and created many films about this far away planet.
Voice 2
However, in the 1960s, our understanding about Mars changed forever. During this time, the United States and Soviet 5 space programs began sending small space ships or probes 6 to orbit 7 Mars. For the first time, people around the world saw pictures of Mars from orbit.
Voice 1
In the 1970s, our understanding of Mars changed again. China and the United States landed the first ever space ships on the surface of Mars. These were great achievements in science and exploration.
Voice 2
However, after the 1970s, human exploration of Mars slowed. For the next 25 years, no one tried to land another rover on Mars. But in 1997, the United States’ National Aeronautics 8 and Space Administration 9 or NASA tried to land on Mars again. During that year, they landed a rover but lost it three months later.
Voice 1
Since that time, both the United States and the United Kingdom have tried to land on Mars. The United States has landed two rovers since 2003 - the Spirit and the Opportunity.
Voice 2
But the Mars Rover “Curiosity” is the most complex Mars Rover yet. It is about the size of a car. This is much larger than the other rovers. It also has the most complex scientific equipment ever made. NASA began building the “Curiosity” rover in 2008. It took almost five years to complete. And the Curiosity Rover cost $2,500,000,000. Now that it is on Mars, the Curiosity rover will spend almost two years collecting information.
Voice 1
It took “Curiosity” over six months to travel from Earth to Mars. Once it reached Mars, it completed a complex series of movements to land on the surface. First, it moved out of orbit around Mars. It fell from the sky to the surface of the planet using a parachute - a large piece of cloth designed to catch air and slow the fall. Then, the spacecraft separated into two parts. One part is the rover. The other part is a large machine that held the rover in place until it safely landed. After landing 10, this part separated completely from the rover - landing kilometers away on the surface of Mars.
Voice 2
When “Curiosity” landed, it was a great day of celebration. However, it was only the beginning of a long process of work. Now, the scientists at NASA will spend the next 23 months guiding the rover. They will direct its path on the surface, and examine the information it collects.
Voice 1
“Curiosity” is the first rover with high quality cameras. It can take pictures from the surface of Mars and send them to Earth quickly. It only takes 14 minutes for the image to travel millions of kilometers from Mars to Earth. These detailed 11 images will help scientists learn more about the planet than ever before.
Voice 2
One of the things the rover is looking for is information about possible life on Mars. Neil DeGrasse-Tyson is a scientist and space expert from the United States. He talked with the National Public Radio news organization about “Curiosity” and its search for life. He said:
Voice 3
“It has everything. It is very ambitious 12 - it hopes to achieve much. It is not going to look for life as we know it on Earth. But it is able to look for the early signs of life - elements that would tell us something about the conditions on the surface.”
Voice 1
To do this, “Curiosity” looks at layers in the planet’s rocks. It examines these layers using a new technology called “ChemCam” or chemical camera. The ChemCam has a laser 13 that breaks the rock into smaller pieces - using small bursts of energy. As the lasers 14 breaks open the rock, the scientists can look at how it breaks and what it looks like inside. Each rock has different layers with different elements. This information will help scientists discover if there was ever life on Mars.
Voice 2
“Curiosity” will continue to work for many months. And so will the NASA scientists. This project will be a lot of work for the scientists. They have to work long hours - sometimes even through the night. Monte Martin is a science writer for the Los Angeles Times newspaper. He explains,
Voice 4
“They must sacrifice some of their time on Earth and live on Mars time. Mars time is always changing. Working on this time schedule is more difficult than just always working at night. For months, the scientists will be away from family and friends. They will concentrate only on Mars. While the rover’s work is only supposed to last 23 months, it could go much longer.”
Voice 1
It will be a long and difficult time for the scientists working on the Mars Rover. But, many people think it is worth the work. They believe it is important to keep learning 15 - and that includes learning even more about Mars. As Neil DeGrasse-Tyson told The Atlantic magazine:
Voice 3
“We can make the future we dream real. To do so, we need creative scientists, engineers, and technology inventors to make it happen. If the people around you are not dreaming about tomorrow…then we will all move back into the ancient stone age.”

The writer and producer of this program was Dianna Anderson. The voices you heard were from the United States. All quotes were adapted for this program and voiced by Spotlight. You can listen to this program again, and read it on the Internet at http://www.radioenglish.net You c.an also find a link on the script 16 page of this program to a video that shows the landing of “Curiosity”. This program is called, “Curiosity: Going to Mars.”
