MAVEN Spacecraft Takes Off For Mars

This week, a “robotic explorer” left Earth on its way to Mars.

It should get there next September. Mars is more than 700 million kilometres away.

The explorer is going to Mars to try to solve some of the planet’s mysteries.

For instance, why is Mars now a cold, dry planet when it started out warm and wet?

The Associated Press reports that “the early Martian atmosphere was thick enough to hold water and possibly support microbial life.”

Scientists at NASA want to know what happened to change that.

Human Activity Responsible For Global Warming: UN Report

A group of scientists associated with the United Nations has just issued a report on “climate change.”

The Intergovernmental Panel on Climate Change has confirmed that human habits and activity is responsible for global warming and for higher sea levels.

If this continues, according to the report, there will be more dramatic changes in plant and animal life.

Some critics believe that the current situation is more likely due to short-term factors or weather cycles. They believe that the climate situation will change on its own eventually.

But the UN report says the reality is clear and the facts are there.

Luckily, because humans cause the problem, humans can help solve the problem.

First Human Colony Planned For Mars

A Dutch business owner is looking for people who want to live on Mars.

He believes that with proper preparation, a human settlement can exist on the Red Planet.

He said the settlement would provide valuable information for those who support and study life beyond Earth.

The project is called Mars One and nearly 80,000 people–including 35 Canadians–have applied to start a new life on Mars.

Those who are chosen to go would set up a colony, similar to a city.

Supplies for the colony will be sent to Mars beginning in 2016.

The first four settlers are scheduled to be transported to Mars in 2023.

Hadfield Arrives Back On Earth; Videos From His Incredible Journey

In Chris Hadfield’s own words, he is, “safely home—back on Earth, happily readapting to the heavy pull of gravity.”

The Canadian astronaut left Earth to live on the International Space Station (ISS) late last December.

He touched down in Kazakhstan on Monday at 10:31 p.m. (EDT), along with two other astronauts who had been on the ISS.

He will now undergo extensive medical testing to help his body adjust to life on Earth again.

In the five months he was living on the ISS, Chris Hadfield changed the way we all relate to space.

Commander Hadfield’s Son, Evan, Helps Bring Space To Earth

Chris Hadfield is the Canadian astronaut living and working on – and commanding – the International Space Station.

He’s the first astronaut to bring the “space experience” to Earthlings in the form of regular tweets, photos, Facebook posts, videos and even songs.

Hadfield lets us know what experiments he’s working on, what the Earth looks like from his vantage point and what it’s like to live in space.

Hadfield has three children, Kyle (30), Evan (27) and Kristin (26).

Evan lives in Darmstadt, Germany.

He has been helping his father communicate with Earth, via Twitter and other social media websites such as Facebook, tumblr and Soundcloud.

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.

Astronaut Chris Hadfield Debuts Song From Space

Before he left for the International Space Station, Hadfield wrote a song with singer Ed Robertson.

It’s called I.S.S. (Is Somebody Singing?). ISS can also stand for “International Space Station,” which is fitting since the song is about what it’s like to leave the Earth and go into space.

Hadfield has done some incredible things during his time on the ISS. He has made his experience in space accessible to the people on Earth.

He has tweeted messages, conducted live media conferences, sent photos and kept people up-to-date on what the astronauts on the Space Station are doing.

What Hadfield is doing is unique. No astronaut has ever brought space so close to Earth before.

Canadian Astronaut To Take Charge Of Space Station

Canadian astronaut Chris Hadfield will soon become the first Canadian to command the International Space Station.

Hadfield and two other astronauts – Tom Mashburn from the United States and Roman Romanenko from Russia – docked at the ISS on Dec. 21, 2012.

Their Soyuz spacecraft was launched from the Baikonur Cosmodrome in Kazakhstan on Dec. 19.

It took them two days to reach the space station.

The space station is a satellite which orbits the Earth. The size of the crew varies from three to six astronauts at a time.

The crews stay on the space station for up to six months and then are replaced by other astronauts.

Hadfield and his crew will stay for five months.

This mission is Hadfield’s third trip into space and his second visit to the space station.

When he takes over command of the ISS in March, he will become the first Canadian ever to command a spacecraft.

Hadfield can already claim several “firsts” in space.

In 1995, Hadfield was the first Canadian to serve as “mission specialist” on a space shuttle.

He was also the first Canadian to operate the Canadarm while in orbit, and the first Canadian to board the Russian space station, Mir.
