Space Travel and Exploration

"Spirit" and "Opportunity". Those two were sent in January, year of 2004.

Before that a small one called "Sojourner". And now "Curiosity", of course.

So that's 4 altogether. That's not counting those that failed.

Jupiter has the most helium of any planet in our solar system, with about 24% of its composition being helium. The high concentration of helium is due to the planet's massive size and gravitational forces, which prevent the gas from escaping into space.

Space probes without crew can be more cost-effective, smaller, and lightweight compared to manned spacecraft. They can gather scientific data in extreme space environments, such as outer reaches of the solar system, where sending humans is currently not feasible. They also eliminate the risks associated with human spaceflight, allowing for longer missions and more sophisticated scientific studies.

The Skylab space mission returned to Earth on July 11, 1979. It re-entered the Earth's atmosphere and broke up over the Indian Ocean and parts of Western Australia.

Astronauts' weight would vary on different planets due to differences in gravity. Their weight is determined by the gravitational pull of the planet they are on, so they would weigh less on a planet with weaker gravity and more on a planet with stronger gravity.

The United States and Russia have sent the most people to space. Russia holds the record for sending the most individuals overall, while the United States has sent the most people on manned missions to space.

Rockets are launched using jet propulsion because it follows Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. The exhaust expelled at high speed propels the rocket in the opposite direction. This allows the rocket to overcome Earth's gravity and achieve the necessary velocity to reach space.

The cost of building a rocket ship can range from tens of millions to several billion dollars, depending on various factors such as size, complexity, technology, and mission objectives. Companies like SpaceX have estimated the cost of building a Falcon 9 rocket at around $62 million.

Space probes typically contain various scientific instruments and sensors to collect data about their target, such as cameras, spectrometers, and magnetometers. They are controlled remotely from Earth and transmit data back to scientists for analysis. Space probes are often designed for specific missions, whether it be exploring a planet, asteroid, or other celestial body.

"Meteoites" seems to be a misspelling of "meteorites." Meteorites are rocks that have fallen to Earth from outer space, surviving the journey through Earth's atmosphere. They provide valuable information about the composition of the universe and the history of our solar system.

Sea rocket is adapted to its coastal habitat by having a deep root system to anchor itself in sandy soil, and by having small, waxy leaves to reduce water loss due to high winds and salt spray. It also produces seeds with a hard coating to protect them from saltwater exposure and allow them to germinate successfully in the sandy environment.

The International Space Station (ISS) is the largest man-made object in space. It orbits Earth and serves as a microgravity and space environment research laboratory where astronauts conduct experiments in various fields.

There is no scientific evidence or proof of the existence of Anunnaki star gates. The concept of Anunnaki star gates is primarily found in ancient Sumerian mythology and speculative theories.

Just like any other wave phenomenon, its frequency is measured in large multiples

of Hertz (Hz), its wavelength is measured in small fractions of a meter (m), and its

speed is measured in meters/second .

The American space program that placed a man on the moon is NASA's Apollo program. In 1969, the Apollo 11 mission successfully landed astronauts Neil Armstrong and Buzz Aldrin on the moon, making Armstrong the first person to walk on the lunar surface.

The senator who went to space at the age of 77 was John Glenn, a former U.S. senator from Ohio. In 1998, he became the oldest person to travel to space at that time when he joined the Space Shuttle Discovery mission.

The answer is very simple: ANY telescope on earth, under the best possible circumstances, is looking through earth's atmosphere. Imagine trying to see the fine detail in anything looking up at it from the bottom of a swimming pool. That's an earthbound telescope. The Hubble does not have any atmosphere affecting it's view - which gives it 20/20 or better vision. Earthbound telescopes? 20/40 on their very best nights, usually more like 20/60.

As it stands now, all objects delivered to space are transferred by way of chemical rockets. Massive amounts of fuel involved in every lift off. Once in space, other drive systems can be invoked, like ion drives or whatever. Escaping the gravitional forces of Earth from the planet surface is the costly step.

What we need are our young scientists working to discover anti-gravity. THAT would be cool.

It's fuel exhaust, like the exhaust from a car.

Like a car the largest component of rocket exhaust (at least from the combustion of its hydrogen fuel) is water, The white "smoke" you see is essentially steam like you get from a hot kettle/.

If you've taken LSD and expose yourself to space without the necessary precautions, then yes.

If you've taken LSD and expose yourself to space in a spacesuit, then no. (unless there are further complications, whose probabilities will have increased due to your intoxicated and hallucinary state)

If you've taken LSD and are inside a space station or another enclosed room within space then no, unless you die by another (un)related cause.

But generally LSD has nothing to do wether or not you die in space; it does not however increase your chances to act correctly in potentially lethal situations. (it does the opposite)

Alan Shepard flew in the Mercury-Redstone 3 spacecraft, which was also known as Freedom 7.

The launch of the Soviet satellite Sputnik in 1957 is often considered the event that sparked the space race between the US and Russia. This was the first artificial satellite to be put into Earth's orbit, signaling the beginning of the space age and prompting a sense of competition between the two superpowers.

The Global Positioning System (GPS) is a technological innovation gained from space exploration that allows someone to find their exact location on Earth. By utilizing a network of satellites orbiting the Earth, GPS receivers can triangulate their position to within a few meters by receiving signals from multiple satellites.

Most space shuttle missions have been to the International Space Station. The correct term would be to dock at the station, not to land there (since it is not located on land, but is floating in space).

John Glenn rode the Mercury-Atlas 6 rocket, also known as Friendship 7, to become the first American to orbit the Earth on February 20, 1962.
