Anyone who thinks that raw science, such as studying fruit flies is sadly mistaken.

Lika The first dog and the First Animal in Space.

I would argue the

The Soviet Union stunned the world on Nov. 3, 1957, with the launch of Sputnik 2. On board the small satellite was a little dog, Laika, the first animal to orbit Earth. However, Laika was not the first animal in space. The United States and the U.S.S.R. had been putting animals atop rockets since 1947.

In the early days of rocket science, no one knew what the effects of weightlessness would be. Animals — mainly dogs, monkeys and chimps — were used to test the safety and feasibility of launching a living being into space and bringing it back unharmed.

Since then, animals have continued to play an important role in understanding the impact of microgravity on many biological functions. Astronauts have studied all kinds of animals — wasps, beetles, tortoises, flies, worms, fish, spiders, rabbits, bees, ants, frogs, mice, crickets, rats, newts, snails, urchins, moths, brine shrimp, jellyfish, guinea pigs, butterflies, scorpions and cockroaches.

Sputnik and Muttnik

Laika was a young, mostly-Siberian husky. She was rescued from the streets of Moscow. Soviet scientists assumed that a stray dog would have already learned to endure harsh conditions of hunger and cold temperatures. Laika and two other dogs were trained for space travel by being kept in small cages and learning to eat a nutritious gel that would be their food in space.

The dog's name was originally Kudryavka, or Little Curly, but she became known internationally as Laika, a Russian word for several breeds of dog similar to a husky. American reporters dubbed her Muttnik as a pun on Sputnik.

Unfortunately, Laika's trip into space was one-way only. A re-entry strategy could not be worked out in time for the launch. It is unknown exactly how long Laika lived in orbit — perhaps a few hours or a few days — until the power to her life-support system gave out. Sputnik 2 burned up in the upper atmosphere in April 1958.

The first animal astronauts

Although there is no distinct boundary between the atmosphere and space, an imaginary line about 68 miles (110 kilometers) from the surface, called the Karman line, is usually where scientists say Earth's atmosphere meets outer space.

The first animals to reach space — not counting any bacteria that may have hitched a ride on previous rockets — were fruit flies. On Feb. 20, 1947, the United States put fruit flies aboard captured German V-2 rockets to study radiation exposure at high altitudes. In 3 minutes and 10 seconds, the fruit flies reached a distance of 68 miles.

The first mammal in space was Albert II, a Rhesus monkey. Albert I's mission had been unsuccessful, but the second Albert reached a distance of 83 miles on June 14, 1949. Albert was anesthetized during flight and implanted with sensors to measure his vital signs. Unfortunately, Albert II died upon impact at re-entry.

Yeah, it should not have been a competition in the first place.

When Gagarin became the first person in space I wasn't worried like a lot of Americans were, they couldn't understand how the US came in second. I was inspired by such a feat.

They were all heroes to me.

I was 22, & was sitting on the sofa with my first baby just 4 days short of 3 months old, watching it on tv.

I was just fourteen when the moon landing took place and I wasn't a fan of American foreign policy but for the time Armstrong and Aldrin were on the moon I was an American too.

And Canada was a big part of that, which is little known.

Russian spacecraft landed on moon hours before Americans

A previously unheard recording of a Russian spacecraft attempting to beat NASA's Apollo 11 in 1969's race to the moon has been released.

In July 1969, the telescopes at the Jodrell Bank Observatory, in Cheshire, were tracking the Americans' Eagle Lander carrying astronauts towards the moon's surface.

Russian spacecraft out of control and hurtling towards Earth

Sir Bernard Lovell, the astronomer, was among the team listening to transmissions coming from the area of space and began tracking the unmanned Soviet spacecraft Luna 15, which was trying to collect samples of lunar soil and rock and then return to Earth before the US mission.

The recordings from Jodrell's Lovell radio telescope, which were hidden in archives until researchers found them, show the Russian craft orbited the Moon and crash-landed onto its surface at 15:50 on July 21 – just a few hours before the Americans lifted off.

In the newly released recordings, which were made over three days, Sir Bernard, the founder of Jodrell Bank, can be heard narrating events with conversation from the Apollo 11 astronauts in the background.

Sir Bernard notes a change in the orbit of Luna 15 to take it closer to the US landing site and later reports a rumour from a "well-informed source in Moscow" that the craft is about to land.

People in Jodrell's control room can then be heard shouting "it's landing" and "it's going down much too fast" as they track Luna 15's final moments before it crashes.

A voice is later heard saying: "I say, this has really been drama of the highest order."

The recordings have been released by The University of Manchester's Jodrell Bank Centre for Astrophysics to celebrate the 40th anniversary of the Moon landings.

Having written the previous fortunately the space shuttle is a joint venture.
