New Space Mission Will Study Asteroid In 2018

A new joint project between the Canadian and U.S. space agencies will bring a piece of the universe to Earth.

The goal of the mission, known as OSIRIS-REx*, is to study an asteroid.

NASA, working with the Canadian Space Agency, will send a spacecraft to Asteroid 1999 RQ36. A robotic arm will grab pieces of the asteroid.

The spacecraft will be launched in Sept. 2016 and it will reach the asteroid in 2018.

The asteroid will be studied and mapped for about six months in space and then the sample will be brought to Earth in 2023.

Meteorite Lands In Russia

Hundreds of people can walk by your front door every day.

The only time you may notice someone, however, is when they knock. Last week, the universe knocked on Earth’s door.

Thousands of asteroids and meteoroids streak pass planet Earth every year. Some of them enter Earth’s atmosphere where most of them simply burn up—those are called meteors. Any that land on Earth are called meteorites.

When a meteorite landed in the city of Chelyabinsk, Russia last Friday, the world took notice. That’s because it was a particularly large meteorite; one chunk was about the size of a van.

No Signs Of Life On Mars… Yet

Scientists have not found any signs of life on Mars yet, but they say a robotic vehicle called “Curiosity” is helping them learn a lot about the planet’s history and climate.

Curiosity landed on Mars in August 2012 after travelling through space for more than eight months.

It was sent to Mars by scientists from NASA in the United States.

Curiosity is a motorized vehicle called a “rover” which is controlled by scientists back on Earth.

It is about the size of a car and has six wheels that allow it to travel across the planet’s surface and climb over sand and rocks.

It also has a robotic arm, cameras, and instruments such as a scoop, drill and microscope that allow it to examine things it finds on the surface.

Then it transmits the information back to Earth.

The main purpose of Curiosity’s mission is to find out if anything could live on Mars, either now or in the past.

On Nov. 2, NASA scientists held a press conference to discuss what Curiosity had found in its first two months on Mars.

Neil Armstrong, First Man On The Moon, Will Long Be Remembered

Neil Armstrong, the first man to walk on the moon, has died. He was 82 years old.

Armstrong was an American astronaut and the commander of the Apollo 11 spacecraft on its mission to put men on the moon.

Apollo 11 was launched on July 16, 1969, and began orbiting the moon three days later. On July 20, Armstrong and his co-pilot, astronaut Edwin E. “Buzz” Aldrin, took off from Apollo 11 in a small landing craft called Eagle. A third astronaut, Michael Collins, remained in the main ship, orbiting the moon until they returned.

Hundreds of millions of people around the world watched on TV as the Eagle landed on the moon. When Armstrong stepped out of the ship and onto the moon’s surface, he said, “That’s one small step for (a) man, one giant leap for mankind.”*

Armstrong and Aldrin explored the moon for more than two hours and collected about 50 pounds of moon rocks. They left behind a plaque which said: “Here men from the planet Earth first set foot upon the moon. July 1969 A.D. We came in peace for all mankind.”

The Eagle remained on the moon for about 21 hours and then rejoined Apollo 11 for the return trip to Earth. Once the astronauts were back on Earth, they spent 16 days in quarantine to make sure they had not brought back any germs from space.

Two Earth-Sized Planets Discovered

Two planets have been discovered, about 1,000 light years away from Earth.

Both of the planets are about the size of Earth. Kepler-20e is slightly smaller, and Kepler-20f is slighty larger than Earth.

The surface of the planets are too hot for water to exist on them; it would not be possible for life to exist on them either. They are hot because they orbit close to a star very much like our sun.

Kepler-20e has a termperature of about 760 degrees Celcius. (In contrast, Earth’s average surface temperature is 14 degrees Celsius.)

The planets were discovered during a mission by NASA using the Kepler space telescope. They have been combing the skies searching for planets since about 2009.

Space Junk Re-Enters Earth’s Atmosphere

A bus-sized chunk of space trash fell out of the sky on Friday or Saturday, and NASA isn’t quite sure where it landed.

They say it likely landed in the Pacific Ocean off the west coast of the United States. They are fairly certain that it didn’t cause any injuries.

The space junk was made up of fragments of a 6.3 tonne satellite that is no longer in use.

The Upper Atmosphere Research Satellite (UARS) was sent into space in 1991 and hasn’t been used since 2005. Its job was to collect information about chemicals in the atmosphere.

As many as 26 pieces of the satellite weighing up to 135 kilograms likely survived re-entry into Earth’s atmosphere. Most fragments burned up before reaching earth.

Scientists Discover Water On The Moon

Scientists recently found out there is 100 times more water on the moon than they thought there was.

Scientists discovered the water when they looked at some pieces of moon rock.

They found water in tiny samples of magma, which was trapped in crystal. Magma is a rock made from cooled lava.

Canadian Astronaut Chris Hadfield told Teaching Kids the News that the water is a very valuable discovery.

“It’s like finding diamonds or gold in a remote frontier,” Hadfield said.
