Space Travel and Exploration

Edward Cunning in 1920-1940

Werner von Braun during the war developed rockets as a weapon which enabled later developments.

1950s the Russians launched Sputnik 1 in competition with the USA during the Cold War. The USA responded and later so did other nations

A space probe carries various equipment such as cameras, spectrometers, magnetometers, and instruments for analyzing particles, radiation, and temperature. It also includes communication devices for sending data back to Earth and propulsion systems for navigating through space.

Gamma radiation can have both positive and negative effects on seeds. Low doses can stimulate seed germination, increase growth rates, and improve crop yield. However, high doses can cause mutations, cell damage, and even death to the seed, leading to reduced germination rates and poor growth. It is important to carefully control the dosage of gamma radiation to harness its benefits without causing harm.

Galaxies are important because they are the building blocks of the universe and contain stars, planets, gas, and dust. Studying galaxies helps us understand the formation and evolution of the universe, as well as the fundamental processes that govern how galaxies interact and evolve over time. Additionally, galaxies are where most of the visible matter in the universe is concentrated, making them crucial for understanding the structure and dynamics of the cosmos.

World War 2 started it with the German V1 and V2 rocket program. After that it was the start of the Cold War, but the real trigger was the launch of Sputnik 1 by the USSR in 1957. The US feared Soviet domination of space and the ability to launch nuclear weapons from the rockets and space. The Soviets beat the US to launch a living being (Laika the dog) and then a human being into space.

Determined not to left behind, the US launched a massive catchup program and then President John. F. Kennedy made a speech setting the goal of putting a man on the moon by the end of the 60s decade.

In the 70s and 80s, the American Military used the shuttle program to put GPS satellites and other in orbit. A key element of this was to give huge accuracy to its ballistic missiles.

After the fall of the Berlin Wall, cooperation with the Russians and other countries increasingly shaped the program.

A rocket is aerodynamic due to its streamlined design, which helps reduce air resistance and drag during flight. The shape of the rocket, such as its pointed nose cone and tapered body, allows air to flow smoothly around it, improving its efficiency and speed through the atmosphere. Additionally, fins and stabilizers are often used to help maintain stability and control its trajectory.

None. All 12 astronauts that landed there got out and walked around, mostly picking up rocks.

There were 9 manned missions that reached lunar orbit: Apollo 8, 10, 11, 12, 13, 14, 15, 16, and 17.

Apollo 8 just orbited, Apollo 10 just tested the Lunar Lander in lunar orbit (dress rehearsal), and Apollo 13 had a severe malfunction that meant they could not land on the Moon. The other six missions landed 2 astronauts each.

This question can be answered by considering law of consrevation of momentum, m1v1=m2v2. If a person pushes an object double his weight he will be sent with double the velocity in the opposite direction. on earth the person transfers the shoch to the ground so he doesnt move. that's why its hard to move heavy objects in space.

Since 1969, there have been numerous advancements in space exploration, including the development of reusable spacecraft like the Space Shuttle, the launch of rovers to explore Mars, the construction and operation of the International Space Station, the landing of probes on asteroids and comets, and the successful flyby and exploration of Pluto by the New Horizons spacecraft. Additionally, private companies like SpaceX have emerged as key players in the industry, revolutionizing space travel with innovations such as reusable rocket technology.

Radiation will occur, we cant really decrease this - aside from diluting the source. We can put up barriers to block the radiation however. There are three main radiation types of radiation, with varying amounts of penetrative power;

Alpha radiation - which can be stopped with paper or a few cm of air.

Beta radiation - which can effectively be blocked with thin aluminum sheet

Gamma radiation - Which has the most penetrating power, and will take several mm of lead or several feet of concrete to effectively block.

Creating a sleep routine on a spaceship can help the baby adjust to the environment. Ensure the cabin is quiet, dark, and has a stable temperature to mimic their usual sleep conditions. Comforting routines like gentle rocking or white noise can also help lull them to sleep.

Astronauts control the temperature in their space suits using a liquid cooling and ventilation garment (LCVG) system. This system circulates water through tubes in the suit to regulate temperature. Astronauts can adjust the flow of water to maintain a comfortable temperature.

On November 17, 1998, Voyager 1 overtook Pioneer 10 as the most distant man-made object from Earth. As of January 2011, it is around 116 AU from earth, where 1 AU (Astronomical Unit) is 93 million miles (distance of earth to sun).

There are plenty of reasons

1. to learn more about the earth - by studying other bodies in the universe we can put into context what we think we know about earth

2. to challenge our fundamental understanding of physics - by exploring extreme environments we test our understanding of how the universe works to the limits.

3. to satisfy the human desire to learn, explore and discover new things as part of human curiosity

4. Now some companies are exploring space to find means of making a profit - some companies are looking into mining on the moon or asteroids which require exploration to determine if it is worth it.

EVA stands for Extravehicular Activity. It refers to any activity conducted by an astronaut outside of their spacecraft while in space. During an EVA, astronauts often perform tasks such as repairs, maintenance, or scientific experiments.

Nothing man-made has left our solar system yet. The furthest thing is Voyager 1, which is now about 116AU away from Earth, around 10.8 billion miles - at the edge of our solar system.

space probes can search space with cool awesome sweet thrusters, that look cool, answer by dakota

actually space probes search space by orbiting around planets answer by nick jeese dakopta your dumb

No, astronauts do not lose their memory when they are weightless in space. However, some astronauts may experience temporary cognitive changes due to factors such as radiation exposure, sleep deprivation, or stress, which could affect their memory.

Chris Hadfield has been to space three times. He flew on two Space Shuttle missions and commanded the International Space Station during Expedition 35 in 2013.

Yes, the Hubble Space Telescope is still in operation and continues to provide valuable observations about the universe. It has made numerous groundbreaking discoveries and contributed to our understanding of planets, stars, galaxies, and more.

Your weight would be different on the moon compared to Earth due to the moon's weaker gravitational pull. Since gravity is weaker on the moon, you would weigh approximately one-sixth of what you weigh on Earth.

Use of unmanned space craft eliminates the years of training needed for astronauts. It allows for missions of much longer durations, as well as increased distances beyond where humans can safely travel.
