Space Travel and Exploration

It is unlikely that anyone could live on planet HD 181433 b as it is a gas giant with extreme temperatures and no solid surface. Additionally, it is located over 200 light-years away from Earth, making it incredibly difficult to reach and sustain human life.

The New Moon occurred at about 1:00 AM Eastern Time on December 25, so

it's not likely to be visible anywhere in the world at any time on that date, as

it will be too close to the sun (visually).

I assume you are talking about the external tank. I'd say it's more rust colored than brown but no matter . . .

The insulation used on the outside of the tank just happens to be that color naturally.

Your mass is a measure of the amount of stuff you're made of. It doesn't change.

It's like the amount of money in your pocket. You can carry it around anywhere,

and no matter where you are, it doesn't change.

Your weight is a force between you and something else, caused by gravity. The

strength of it depends on both masses ... yours and the other thing, and it also

depends on how far apart you and the other thing are. If the other thing is the

Earth, the force has a certain strength. If the other thing is the moon and you're

on it, then the force has less strength, because the moon has less mass than the

Earth has. And if you're in a space capsule on the way from the Earth to the moon,

then you're pretty far away from anything with much mass, so the force is very tiny.

Plus you're "falling" toward the moon, and you never feel any gravitational force

at all when you're falling.

So ... mass is how much stuff you have. Weight is how your stuff behaves around

other masses.

Yes, astronauts need time to adjust to gravity upon returning from space. Referred to as "space adaptation syndrome," it can include issues with balance and muscle strength. Through rehabilitation and physical conditioning, astronauts gradually regain their ability to walk.

I'm not sure about all of the inventions but some of the most useful ones include the smoke detector (originally used to detect toxic vapors), satelite TV dishes (developed to reduce noise interference), various fire proof materials and the development of medical internal imaging and of course velcro.

Hope it helps.

Space exploration in the US has seen progress with the development of new spacecraft like SpaceX's Crew Dragon and NASA's Artemis program aiming to return humans to the Moon. Additionally, commercial companies like Blue Origin and SpaceX are expanding their capabilities for space tourism and exploration. The US government remains committed to supporting space exploration through initiatives like the Space Force and continued funding for NASA.

Given current technology, whilst orbiting the moon one fires a chemical propellant rocket to begin trans-terrestrial injection. This rocket adds enough speed to escape the moons gravity. If the TTI burn had the proper impulse and was executed at the proper time, the matter of returning to Earth is all about gravity.

A spacecraft can travel forever in space because there is no air resistance or friction to slow it down. Once a spacecraft achieves a certain speed, it will continue to travel at that speed unless acted upon by another force, such as gravity or propulsion systems.

Surrounding space refers to the environment or area that surrounds a particular object or location. It can include the atmosphere, other objects in proximity, or anything that is around the specified area.

The spacecraft that Yuri Gagarin flew in for the first human space flight in 1961 was called Vostok 1.

It was launched on August 8, 2001 and returned September 8, 2004. Crash landing due to a fault in the parachute.

It collected samples of the solar wind.

Launching a golf tee into orbit from 100,000 feet would require a small rocket, potentially a sounding rocket or a suborbital rocket. These rockets are typically between 20-70 feet in length and range in weight from a few hundred to several thousand pounds. The specific size of the rocket would depend on factors such as payload weight, desired trajectory, and propulsion system.

People who travel into space are typically referred to as astronauts.

Petroleum products are less commonly used in rockets because they are heavier and less energy-dense compared to other rocket fuels like liquid hydrogen or hydrazine. These other fuels provide better performance in terms of thrust and efficiency, making them more suitable for rocket propulsion. Additionally, the combustion of petroleum products can produce more harmful emissions and residues compared to other fuels.

American human flight programs were; Mercury, Gemini, Apollo, Shuttle, the recently nixed Orion, and the up and coming SpaceX Falcon series. The last of which is the largest private space venture in history.

Three from the Apollo missions and two from the Soviet Unions Moon Walker program, so five total.

if moon is formed like fission theory i.e. "moon is the part of the earth"

so the drawback is that how centripetal force is greater like that it eject some mass.and if we agree this that moon is formed due to centrifugal force of earth so the point is that the centrifugal force is maximum near the equator and moon should lies on the equatorial plane but it is not.

Yuri Gagarin of the Soviet Union was the first person in space in 1961. The first Asian person in space was Japanese astronaut Toyohiro Akiyama, who flew aboard the Soviet Soyuz TM-11 mission in 1990.

Rockets are able to carry heavy payloads into space, making them ideal for launching satellites, spacecraft, and cargo. They offer a quick and direct path to space with high speed, enabling efficient travel to other planets or celestial bodies. They are versatile and can be used for various missions, such as satellite deployment, crewed missions, and scientific research.

Historical discoveries such as Newton's laws of motion, Kepler's laws of planetary motion, and understanding of gravity paved the way for space exploration. The development of rocket technology by individuals like Konstantin Tsiolkovsky and Robert Goddard also significantly advanced mankind's ability to venture into space. Additionally, the discovery of cosmic microwave background radiation provided evidence for the Big Bang theory, further shaping our understanding of the universe and its origins.

Though many accepted the geocentric model of the universe, it was designed by the famous astronomer Ptolemy.

there were 9 Apollo trips to the moon:

A-8, A-10, A-11, A-12, A-13, A-14, A-15, A-16 and A-17.

Each Apollo mission carried three men, so 9 x 3 =27.

BUT, 3 of those 27 went twice, so 27 - 3 = 24 individual men.

As far as landings on the moon, there were only 6 landings, which carried 2 men each time, so 6 x 2= 12 people who've walked on the moon (so far).

I already have. The space program wasn't getting anywhere as long as it depended

on me for its funding. I was truly gratified, thrilled, and delighted when the US created

the National Aeronautics and Space Agency (NASA) at the federal level to take over

the job of not only paying for it, but also planning and operating the space program.

They have the time, money, and all the other necessary resources to do it right, and

it's a really important program that must be continued and adequately supported.

How long can a man survive in an airtight room that has a volume of ? Assume that his surface area is 1.70m^2.

Vol=27m^3

SA=1.70 m^3

(27M^3)(0.2094E10) =

5653.8 liters O2

= (4.83cal)(5653.8 liters O2)

(1.7m^2)(35cal/M^3*liters) =

= 59.5 cal/hr

(27307.854 cal/M^2 ) / (59.5 Cal/air)=

= 458.95 Hr
