NASA's Artemis deep space lunar mission to include Canadian astronaut

Space Exploration Continues: NASA's Artemis deep space lunar mission to include Canadian astronaut.

Interesting Space Facts:

A Van Allen radiation belt is a zone of energetic charged particles, most of which originate from the solar wind, that are captured by and held around a planet by that planet's magnetic field. Earth has two such belts and sometimes others may be temporarily created. The "belts" were a hazard for the Apollo (Moon) missions. The astronauts had low exposure in "belts" due to the short period of time spent flying through them. Apollo flight trajectories tried to avoid "belts" when possible.

Artemis, in Greek religion, is the goddess of wild animals, the hunt, and vegetation and of chastity and childbirth; she was identified by the Romans with Diana. Artemis was the daughter of Zeus and Leto and the twin sister of Apollo.

If Earth had two moons, it would be catastrophic. An extra moon would lead to larger tides and wipe out major cities like New York and Singapore.

Besides the 2019 Chinese rover Yutu-2, the only artificial objects on the Moon that are still in use are the retroreflectors for the lunar laser ranging experiments left there by the Apollo 11, 14, and 15 astronauts, and by the Soviet Union's Lunokhod 1 and Lunokhod 2 missions.

The Outer Space Treaty says that no matter whose national flags are planted on the lunar surface - no nation can 'own' the Moon. As of 2019, 109 nations are bound by the Treaty, and another 23 have signed the agreement but have yet to be officially recognised. In the future, different countries could be parts of the moon.

The Outer Space Treaty says that astronauts shall be regarded as the envoys of mankind; States shall be responsible for national space activities whether carried out by governmental or non-governmental entities; States shall be liable for damage caused by their space objects; and. States shall avoid harmful contamination of space and celestial bodies.

With the NASA Artemis program, NASA will land the first woman and next man on the Moon by 2024, using innovative technologies to explore more of the lunar surface than ever before.

It will take some time for Artemis to get to the moon. While the journey to the Moon takes 3 days, reaching Mars is a far lengthier and more complicated goal.

The USA space agency (NASA) has formally outlined its $28bn (£22bn) plan to return to the Moon by 2024. NASA is still aiming for human missions to Mars in the 2030s.

The Moon's gravity at the surface is only 17% that of Earth's. Using the same force of a jump on Earth, you could rise about 3 metres (10 feet) off the ground and stay in the air for about 4 seconds.

Gravity on Mars is only about 38% of Earth's. So, if you weighed 100 pounds on Earth, you would only weigh about 38 pounds on Mars. And if you can jump one meter (3.3 feet) high on Earth, you would be able to jump 2.64 meters (almost 9 feet) high on Mars.

Outer space can be deadly. The most immediate threat in the cosmic vacuum is oxygen deprivation. Assuming that you don't hold your breath during decompression, it will take about 15 seconds for your O2 deprived blood to get to your brain. When this happens, you'll pass out - and then you will die.

Innovation Minister Navdeep Bains announced Wednesday that the Canadian and American governments have signed a new treaty outlining Canadian participation in the Artemis missions and locking in a seat for a Canadian astronaut on the 2023 launch.

The Moon is really Earth's only permanent natural satellite.

The Moon always shows Earth the same face.

The Moon's surface is actually dark.

The Moon is drifting away from the Earth. The moon is slowly moving away from Earth at a rate of 3.8 centimeters (1.5 inches) per year, but the speed of its retreat has varied over time.

The Lunar Gateway, or simply the Gateway, is certainly a planned small space station in lunar orbit intended to serve as a solar-powered communication hub, science laboratory, short-term habitation module, and holding area for rovers and other useful robots.

The Moon is really an astronomical body that orbits the Earth as its only permanent natural satellite. Basically, the Moon is neither a star nor a planet, though it is always by the Earth's side and rotates with us synchronically as a satellite.

The Moon is made of rock and metal (just like the Earth and the other rocky planets) (Mercury, Venus and Mars). The crust, the Moon's outer shell, is covered by lunar soil, also called regolith: a blanket of fine rock particles, varying between three and 20 metres (10 to 65 feet) deep.

The moon is the brightest and largest object in our night sky. The Moon makes Earth a more livable planet by moderating our home planet's wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years.

A Moon landing is really the arrival of a spacecraft on the surface of the Moon. This includes both crewed and robotic missions. The first human-made object to touch the Moon was the Soviet Union's Luna 2, on 13 September 1959. The United States' Apollo 11 was the first crewed mission to land on the Moon, on 20 July 1969.

India has announced plans for a third lunar mission, months after its last one crash landed on the Moon's surface.

China moon landings were on near side of Moon until 3 January 2019, when the Chinese Chang'e 4 spacecraft made the first landing on far side of Moon.

Main countries with space agencies are: the United States, Russia, Europe, Japan, and Canada. The ISS has been the most politically complex space exploration program ever undertaken. Facilities around the world support the operation and management of the International Space Station.

While a number of countries have built satellites, as of 2019, eleven countries have had the capability to send objects into orbit using their own launch vehicles. Russia and Ukraine inherited the space launchers and satellites capability from the Soviet Union, following its dissolution in 1991.
