Why should you stop spending money on space exploration?
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 you live in a vacuum?
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
What were the first American space missions called?
The first American space missions were called Mercury missions. These missions aimed to put astronauts into space, gather data on human spaceflight, and pave the way for more ambitious missions. The Mercury program ran from 1960 to 1963.
What rocket carried Gene Rodenberrys ashes into space?
Gene Roddenberry's ashes were carried into space aboard a Pegasus XL rocket in 1997. The rocket was launched by the company Celestis, which offers memorial spaceflights for cremated remains.
Which dog was sent in space in 1975?
The dog that was sent into space in 1975 was a Russian dog named Bars. Bars was one of the dogs involved in the Soviet space program's experiments testing the effects of space travel on living organisms.
How much space is needed around a foosball table?
A good rule of thumb is to have at least 3-4 feet of space around all sides of a foosball table to allow players to move freely and comfortably during gameplay. This extra space helps prevent collisions and ensures the game is enjoyed without feeling cramped.
Why do stars appear to be at rest though they are moving very fast?
Simply because they are so far away from you.
When you see a passenger airliner cruising at 35,000 feet over your neighborhood,
it doesn't look like what you'd expect from an object moving at 500 miles per hour.
Even the nearest astronomical body ... the moon ... is moving in its orbit at more than
2,200 miles per hour, and you can't actually see it moving.
Every star in the night sky is many millions of times farther away from you than
the moon is.
Items that can be brought to space include food, water, clothing, tools, scientific equipment, and personal hygiene products. Advanced planning and engineering are required to ensure that objects are safe for use in the unique conditions of space.
How can a rocket lift off the ground using action reaction forces?
A rocket lifts off the ground by expelling high-speed exhaust gases downward through its engine nozzle. This action creates a reaction force (thrust) in the opposite direction, pushing the rocket upwards. This follows Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
Is space exploration a good thing and why?
Yes, space exploration is a good thing. It is very exciting, and it is something that
everybody is interested in, and we can learn a lot of things from it about how space
and even our Earth work, and where they came from, and where they are going.
These are subjects that everybody is curious about. If we learn about them from
space exploration, then we will know some answers to our questions.
How long does it take to travel from one galixy to another?
At the speed of light, it takes millions of years. For example, the Andromeda galaxy, which is the closest galaxy to our Milky Way galaxy, is about 2.5 million light years away, that is, traveling at light speed it would take 2.5 million years to get there.
What is the spectroscopes furture in space exploration?
Spectroscopes will continue to play a crucial role in space exploration by helping scientists analyze the composition, temperature, and density of celestial objects. They will be used to study exoplanet atmospheres, identify planetary compositions, and explore the origins of the universe. Advances in spectroscopic technology will enable researchers to gather more detailed and accurate data from distant objects in the universe.
No, it is a red-orange color due to the deposition of iron (or, due to the high iron content of the soil), hence the name "The Red Planet"
A rocket moves through space by pushing exhaust gases out of its engine in the opposite direction with great force, according to Newton's Third Law of Motion. This generates thrust that propels the rocket forward. By continuously firing its engines and adjusting its trajectory, a rocket can navigate through space to reach its destination.
Why are humans concerned about removal of trees?
Because the atmosphere of the Earth is what it is largely as a result of millions of
years of the existence of vast forests of trees and ... coincidentally and perhaps
inconveniently ... humans depend on that atmosphere for breathing purposes.
One way to divide the planets could be by classifying them as terrestrial planets (Mercury, Venus, Earth, Mars) and gas giants (Jupiter, Saturn, Uranus, Neptune). Terrestrial planets are small, rocky, and have solid surfaces, while gas giants are much larger, composed mainly of gases and liquids, and lack a solid surface.
The first thing that will have to improve is cost.
Once the cost starts to come down you can afford to improve comfort and speed, those two things are what keeps the average person from traveling from planet to planet.
So when the cost comes down you can afford to make the process comfortable enough that the average person could endure the trip, making it faster will make it cheaper again, making space travel more available to everyone.
What is the difference about the rainforest and Arctic?
The main difference between the rainforest and the Arctic is the climate and ecosystem. Rainforests are characterized by high temperatures, abundant rainfall, and dense vegetation, while the Arctic has cold temperatures, frozen land and water, and minimal vegetation. The biodiversity and species in each region are adapted to thrive in those specific environments.
Scientists are concerned that static electricity will be a bigger problem for astronauts because in space there is no atmosphere to dissipate built-up charge, leading to higher levels of static electricity. This can create issues with sensitive equipment, affect communication systems, and even pose a risk of sparks in a high-oxygen environment. Astronauts in spacesuits can build up static charges that may interfere with electronic devices or even pose a risk to the astronauts themselves.
What is a US space explorer called?
He or she is called an 'astronaut' regardless of his or her
gender identification, affiliation, history, or preference.
What was Sally rides route to the moon?
Sally Ride did not travel to the moon during her time as an astronaut. She was the first American woman in space, flying aboard the Space Shuttle Challenger in 1983. The moon missions were part of the Apollo program in the late 1960s and early 1970s.
That would depend on the intensity of the incoming solar radiation ... essentially
the planet's distance from the sun ... as well as on the size of the planet, which
determines its total absorption area.
Mercury doesn't have to absorb sunshine as effectively as Pluto does, in order to
maintain any given surface temperature.
(You didn't say the "freezing point" of what ?)
Who is the first man that went into space?
The first man to go into space was Yuri Gagarin, a Soviet astronaut who orbited Earth aboard the Vostok 1 spacecraft on April 12, 1961.
