Space Travel and Exploration

Some notable space probes and achievements include:

• Voyager 1 and 2, which have left our solar system and are now in interstellar space.
• The Mars Curiosity rover, which has been exploring the surface of Mars since 2012.
• The New Horizons probe, which provided the first close-up images of Pluto and its moons.
• The Cassini spacecraft, which studied Saturn and its moons for over a decade before plunging into the planet's atmosphere.

As of August 2021, there have been over 580 human spaceflights into space, with multiple trips made by some astronauts. This includes missions to the International Space Station, as well as previous spaceflights conducted by various space agencies around the world.

Space shuttle Columbia broke apart on reentry on February 1, 2003.

If a flying piece of debris were to rip a hole in a spacesuit during a spacewalk, it could lead to a rapid loss of air pressure. The astronaut would experience decompression sickness and could potentially lose consciousness. Immediate actions would be needed to prevent further harm, such as quickly locating and repairing the hole or returning to the spacecraft.

The speed of a rocket on takeoff from Earth varies depending on the rocket design and mission requirements. Typically, rockets reach speeds of around 17,500 mph (28,000 km/h) in order to overcome Earth's gravitational pull and enter orbit.

Yuri Gagarin went to space once, on April 12, 1961, becoming the first human to travel into space.

Yuri Gagarin was the first Russian to orbit the Earth. He accomplished this feat on April 12, 1961, aboard the spacecraft Vostok 1.

There are the usual things that could potentially happen, which may involve mechanical and electrical failure. The life support system could go down for example, or a stray meteor might rip through part of the vehicle. There is also thought to be a lot more radiation, that would make the pilots I'll or even kill them if they are insufficiently protected from it. It would be a very long journey in a small space, so the astronauts may have psychological problems also, and may struggle to get on with each other.

Privatizing space exploration can drive innovation and efficiency, but removing American taxpayer funding entirely could limit access to space for scientific purposes and national security interests. A balanced approach that includes both public and private partnerships may be the most effective way to advance space exploration.

It was a 'race' between the two superpowers during the cold war era, USA and the USSR. Both countries can claim different victories, USSR sending the first man into space, who made one complete orbit of the earth. The USA were the first to land a man on the moon in June 1969.

The Hubble space telescope has no interfering forces and it's design enables it to capture more things also the people at NASA take a tiny sand grain size dot of the picture it took and they enlarge it which shows even more stuff!

1. all of the gasses in your body would collect and violently diffuse out of your body. Its kind of like getting the bends but a thousand times worse and a bit more explosive. you not only need air to breath but you need the pressure to be maintained outside to keep your insides inside. IOW you die within seconds.

2. if you are in a matterless part of space you would be susbjected to an immediate deep freeze. 0 Kelvin cold, like really, really, really cold. cold enough to slow your molecules to a crawl and then grind them to a halt.

2.5 if you are say near a nice friendly star you could be half baked, the part facing the star would be bombarded with a nice spectrum of stellar radiation and cooked at thousands if not millions of degree depending on how close you are. while the other side not faceing the star would remain frozen, in space no atmosphere, so molecules only move if there is an energy source to move them.

3. your corpse will float on in the world indefinately, breaking down very slowly over billions of years via contact with various matters and energies eventually being broken down to its base elements or even subatomic particles and becoming part of the creation of some star or planet of some other thing.

circle of life baby...

conclusion: you would die and become space dust.

Astronauts have landed on the Moon, which is not a planet but a natural satellite of Earth. Humans have not yet landed on any other planets in our solar system.

In 2001, the first module of the International Space Station (ISS) was launched and connected in orbit. The first space tourist, Dennis Tito, also traveled to the ISS aboard a Russian spacecraft. It was a significant year for international cooperation and space exploration.

It was Gemini 3. The first two in the Gemini program were unmanned.

Some notable space probes sent by the US include Voyager 1 and 2, Pioneer 10 and 11, and Mars rovers like Curiosity and Perseverance. The USSR launched space probes like Venera 7, Luna 2, and Mars 3.

The Baikonur Cosmodrome, also called Tyuratam. It is the world's first and largest operational space launch facility. It is located in Kazakhstan, about 200 kilometers (124 mi) east of the Aral Sea.

The number of people a rocket can carry depends on its design and purpose. Some rockets, like the SpaceX Crew Dragon, are designed to carry up to 7 astronauts while others are used for cargo missions and do not carry any people.

Rockets are affected by thrust (produced by engines), drag (air resistance), gravity (pulling the rocket down), and mass (the rocket's weight and payload). These factors impact the rocket's ability to overcome gravity and travel through the atmosphere.

The eccentricity of an ellipse is a number related to how "egg-shaped" it is ... the

difference between the distance through the fat part and the distance through the

skinny part. That's also related to the distance between the 'foci' (focuses) of the

ellipse.

The farther apart the foci are, the higher the eccentricity is, and the flatter the ellipse is.

Comets have very eccentric orbits.

When the two foci are at the same point, the eccentricity is zero, all of the diameters

of the ellipse have the same length, and the ellipse is a circle. All of the planets have

orbits with small eccentricities.

The total amount that NASA has been budgeted from 1958 to 2008 comes to around $416 billion dollars, an average of $8.2 billion per year.

When measured in real terms (adjusted for inflation), it is closer to $790 billion, or an average of $15.8 billion dollars per year over its fifty year history (According to the Office of Management and Budget and the Air Force Almanac).

As of now, the latest spacecraft sent to outer space is the James Webb Space Telescope (JWST), which was launched in December 2021. It is an advanced observatory that will help astronomers study the universe in infrared wavelengths.

Space officially begins at the Kármán line, which is located approximately 62 miles (100 kilometers) above sea level. This boundary demarcates the edge of Earth's atmosphere and the beginning of outer space.

After years of sampling the conditions in space, some genius mentioned to them

that if they were going to send a human person out there, then in order to avoid

having him inflate like a balloon, become angry and uncomfortable due to being

unable to breathe, have every chromosome and gene in his body toasted by

solar x-rays and gamma rays, freeze solid in the earth's shadow, be unable to

communicate in any way, and burn up in the direct sun, it would be wise to

provide him with a shell that could simulate all the conditions to which he's

become accustomed during a million years on earth, and which he could take

along with him wherever he goes in space.
