Laika, a three-year-old stray dog from the streets of Moscow, Russia, was sent up to space in Sputnik 2. Scientists believed animals could help understand the effect of space flight on humans. However, since they hadn’t yet, at the time, figured out the technology to de-orbit, it was a one-way flight. Laika died soon after her flight, possibly from overheating caused by a malfunctioning spacecraft.

American satellite Explorer 6 transmitted crude pictures of a sunlit area of the Central Pacific Ocean and its cloud cover while it was crossing Mexico. 

NASA launched the Pioneer 5 space probe, via a Thor-Able 4 rocket, to investigate the interplanetary space between Earth and Venus. The probe was designed to provide information on solar flares, radiation and interplanetary magnetic fields.

Soviet cosmonaut Yuri Gagarin completed an orbit of the Earth on the Vostok 1. This was Gagarin’s first and only spaceflight. The flight lasted 108 minutes and Gagarin parachuted out of the capsule when it was 4.3 miles (seven kilometers) from the planet’s surface. However, he didn’t man the mission – it was controlled either by an auto-pilot mechanism or from the ground.

American astronaut Alan Shepard piloted the Mercury-Redstone 3 (also called Freedom 7) to demonstrate humans could withstand the high gravitational forces of launch and landing. He completed a 15-minute suborbital flight before landing in the North Atlantic, off the coast of the Bahamas.

Scottish spaceport set for blast-off after £2m boost

Plans that would see a remote island in the far north of Scotland become home to the UK’s first spaceport have come a step closer to fruition after a major funding boost. Unst in Shetland, the most northerly inhabited island in the UK, has been selected as the ideal spot to construct a commercial satellite launch pad as the nation bids to join the new and rapidly growing global space sector.Now Shetland Space Centre (SSC) is set to benefit from investment of more than £2 million from private equity firm Leonne International, which will own a 20 per cent stake in the venture.

A mysterious deep space radio burst is sending signals to Earth every 16 days . A mysterious object in a galaxy 500 million light-years away is confusing scientists with its signals . It appears to be transmitting signals that reach Earth in a repeating, 16 - day pattern, but researchers have no idea why.

Fast radio bursts last only a few milliseconds, which makes it difficult to accurately determine where they have come from . The fast radio burst that repeats every 16 days was detected by the Canadian Hydrogen Intensity Mapping Experiment, a radio telescope designed and built by several

Apollo 8 departed from Earth's orbit at 6:10:17 UTC, going into lunar orbit and circling it 10 times. Commander Frank Borman, Command Module Pilot James Lovell and Lunar Module Pilot William Anders marked a list of firsts that include: first humans to see the Earth as a whole, enter the gravitational force of another celestial object, to photograph Earth from space, see the far side of the moon and see an Earthrise.

Apollo 11 Mission Commander Neil Armstrong made history when he set foot on the moon. Along with astronaut Buzz Aldrin (pictured), Armstrong landed the lunar module at 20:18 UTC and, six hours later, stepped outside. He was joined by Aldrin some 20 minutes later. Armstrong and Aldrin also became the first humans to take pictures on and off the moon.

Lunokhod 1 was the first of two unmanned rovers launched by the Soviet Union. Weighing 1,667 pounds (756 kilograms), it landed in the Mare Imbrium (also called Sea of Showers or Sea of Rains).

The Soviets launched the first space station of any kind, the Salyut 1 (R), to conduct tests and scientific research in low-Earth orbit. An accident on Soyuz 11 forced the Soviets to halt their space missions as their capsules had to be redesigned. This took too long and it was decided to terminate the Salyut 1 after 175 days.

They met on a dating app, but he was really looking for a getaway driver in a bank robbery

When a 40-year-old Massachusetts woman agreed to meet up with a man she’d matched with on a dating app, she couldn’t have imagined how badly their first date would go.But moments later, Christopher Castillo came sprinting back to her car, sweating profusely and clutching a gun, hat, sunglasses and $1,000 in cash. He urged the woman to speed away. And their first date quickly turned into a slow-motion disaster as Castillo tangled with police officers and the woman unwittingly found herself becoming a suspected accessory to a bank heist.

Mir’s Base Block was launched into orbit by a Soviet Proton launcher, becoming the world’s first modular space station – assembled over the 10 years it was orbiting Earth. During its 15 years of service, it remained the largest artificial satellite in orbit.

The Voyager 1, launched in 1977, took the first ever "family portrait" of the solar system. It was a mosaic of 60 images that only showed six planets since Mercury was too close to the sun to be seen, Mars could not be detected by the camera and Pluto was too small. The sun was seen in the center as just a point of light.

Cosmonaut Valeri Polyakov lived aboard Mir Space Station for just over 437 days continuously. His combined space time, over multiple missions, is more than 22 months. His residency was helpful for scientists to study biomedical effects of long-term spaceflight. 

Mars Pathfinder took four minutes to enter the Martian atmosphere and land in the Ares Vallis region. It deployed the Sojourner Rover soon after, which conducted experiments to analyze the atmosphere, climate and geology of the planet.

The first module of the International Space Station (ISS) was launched by a Russian Proton rocket. The world's first multinational space station would continue to grow over subsequent missions until it became the largest man-made object in Earth's orbit and the largest satellite of Earth. The station has also been continuously occupied for more than 16 years, making it the longest continuous human presence in space.

A Delta II rocket carried Kepler, NASA’s first planet-hunting spacecraft, on its mission to look for Earth-like exoplanets. It would orbit the Sun every 372 days, observing an area and selecting stars for further study.

SpaceX sent a previously used Falcon 9 into space, carrying communication satellites. The first stage of the rocket had been used in an April 2016 NASA mission. It successfully returned to Earth and landed on a drone ship in the Atlantic Ocean. 

The private space company successfully completed the flight of the Falcon Heavy that can lift up to 141,000 pounds (64 metric tons) – a mass greater than a 737 fully-loaded jetliner. During its demo flight, the huge rocket launched Elon Musk’s cherry-red Tesla Roadster and its dummy astronaut, "Starman" (pictured), into orbit around the sun. 

The Parker Solar Probe became the closest ever man-made object to the sun. The record of 26.55 million miles (42.73 million kilometers) was previously held by the Helios 2 spacecraft, which was launched jointly by NASA and Germany’s DFVLR. The Parker probe is expected to approach within 4.3 million miles (6.9 million kilometers) from the center of the sun and the mission goals include understanding the flow of energy around the corona (outer layer of the sun’s atmosphere).

NASA spacecraft New Horizons traveled to Ultima Thule, a trans-Neptunian object located four billion miles (6.5 billion kilometers) from Earth. The journey, which was made in six hours and eight minutes, marks the furthest point in space humanity has explored to date. Photographs sent back from the flyby – the space craft was 2,200 miles (3,500 kilometers) away – show two sphere-like objects fused together. The largest is believed to be 21 miles (33 kilometers) long.

(Pictured) This image made available by NASA on Jan. 2, 2019, shows the size and shape of the object Ultima Thule. 

On this day, the Chinese government claimed to have successfully landed a space probe on the far side of the moon. The probe – Chang’e-4 – landed in the South Pole-Aitken Basin, according to a statement issued by country's space agency. The event now means China is one of only three countries in the world to have made soft-landings on the moon – the other two are the U.S. and the former Soviet Union.

On Jan. 15, 2019, China National Space Administration revealed that seeds taken up to the moon by Chang'e-4 have sprouted, marking the first time any biological matter has grown there. "Learning about these plants' growth in a low-gravity environment would allow us to lay the foundation for our future establishment of space base," said Professor Xie Gengxin, the experiment's chief designer.
