What does a NASA researcher do?
A NASA researcher conducts scientific studies and experiments related to space exploration, planetary science, or aeronautics. They may specialize in areas such as astrophysics, planetary geology, or aerospace engineering to further our understanding of the universe and develop technologies for space missions.
What materials are used to make space shuttles?
Space shuttles are primarily made of aluminum alloys, reinforced carbon-carbon (RCC) for the heat shield, and thermal protection tiles. The external fuel tank is made of aluminum and the solid rocket boosters use a combination of aluminum, steel, and composite materials. Various other materials such as titanium, ceramics, and specific polymers are also used in different components of the space shuttle.
What is the first space laboratory?
The first space laboratory was Skylab, launched by NASA in 1973. Skylab was designed to study the effects of long-duration spaceflight on the human body and conduct scientific experiments in microgravity.
What is the largest space shuttle?
The Space Shuttle orbiter, with a length of 122.17 feet and a wingspan of 78.06 feet, was the largest space shuttle. The Space Shuttle program operated a total of five orbiters: Columbia, Challenger, Discovery, Atlantis, and Endeavour.
What is the chronological order of the American space programs Apollo Mercury and Gemini?
Mercury was first, followed by Gemini and Apollo.
When was the first space flight?
The first space flight was in 1981, Columbia was the first to make a space flight. The shuttle was a masterpiece of engineering. After being launched into space it could be flown like a plane.
How does a Saturn V rocket work?
Saturn V lifts off, clears the tower, then when in space, it will separate the bottom, again and again, then the command and service module pop out the top. Form there, the Lunar module (aka: lunar lander) will be picked up from the commend module's top. from there, the service module will boost the space crafts to the moon, and will detach. the Lunar module will land softly on the moon with it's boosters. After being on the moon, the space craft will boost its self up. The lunar module pilot will attach them selves to the command module. Next, the astronauts will command the service module to boost them selves so far. Then they will separate; first, the Lunar module, then the service module, then they will reenter. At the last moment, the astronauts will release the parachutes, finally, they will splash down in the south Pacific. From there, a crane will pick them up and onto a concrete dock. The astronauts come out.
What does condensation create in the atmosphere?
Condensation in the atmosphere creates clouds, which are formed when water vapor in the air cools and condenses into tiny water droplets or ice crystals. These clouds play a critical role in Earth's climate and weather systems by affecting temperature, precipitation, and energy balance.
NASA, the National Aeronautics and Space Administration, was established on July 29, 1958. Its headquarters is located in Washington, D.C., United States.
When was NASA first mission to space?
NASA's first mission to space was the Explorer 1 satellite, which was launched on January 31, 1958. This mission marked the beginning of the United States' participation in the exploration of outer space.
When did NASA launch its Mercury mission?
The first launch in the Mercury Program was on 21 August 1959 and was designated as JL-1 and was called Little Joe. It was designed as a sub-orbital flight and it truly was. The mock-up capsule was fired by an electrical fault 35 seconds before scheduled, flew to an altitude of 0.4 miles and lasted a total of 20 seconds. The mission report read: Failed to meet objectives. More then two years later the MA-5 mission carrying Enos the Chimp made two orbits on his flight and survived. On 5 May 1961 Alan B. Shepard, Jr made his sub-orbital flight to an altitude of 116.5 miles in Freedom Seven in a mission that lasted for 15 minutes and 28 seconds, traveled 303 miles and reached a speed of 5,134 miles per hour.
What fuel does the space shuttle use?
The space shuttle uses liquid hydrogen as the main engine fuel, along with liquid oxygen as an oxidizer. The shuttle uses two solid-fuel boosters (SRBs) that contain a mixture that is mostly aluminum powder, iron oxide, and ammonium perchlorate (the oxidizer
, which is about 70% of the chemical mix).
While in orbit, the space shuttle uses hydrazine (N2H4) and nitrogen tetroxide (N2O4) for thrust, as these chemicals are relatively stable for a long duration in space and provide excellent thrust to weight ratio. However, these chemicals are very poisonous, and after the shuttle lands the crew remains inside for several minutes to allow any remaining reaction gases to dissipate.
What are the names of all of the Apollo crew members?
Some of the Apollo crew members include Neil Armstrong, Buzz Aldrin, and Michael Collins from Apollo 11; Jim Lovell, Fred Haise, and Jack Swigert from Apollo 13; and Gene Cernan, Harrison Schmitt, and Ronald Evans from Apollo 17.
What was the name of NASA first spaceship?
Explorer-I, officially Satellite 1958 Alpha (and sometimes referred to as Explorer 1), was the first Earth satellite of the United States, having been launched at 10:48pm EST on 31 January 1958.
What is the yearly salary for a NASA astronaut?
Q. What is an astronaut's salary?
A. Salaries for civilian Astronaut Candidates are based on the Federal Government's General Schedule pay scale for grades GS-12 through GS-13. Each person's grade is determined according to his/her academic achievements and experience. Currently, a GS-12 starts at $65,140 per year and a GS-13 can earn up to $100,701 per year.
Becoming an astronaut is extremely competitive, with an average of more than 4000 applicants for about 20 openings every two years. Astronaut recruiting occurs periodically. Becoming an astronaut is very difficult, but it has a good salary, and it is fun to become an astronaut, you'll be known world wide.
Alot. More than a teacher's salary.
How many astronauts travel in the Space Shuttle at once?
The shuttles have the capacity to carry 8 astronauts, but usually only 7 are on each mission. Sometimes the extra seat will be taken by the astronaut being returned to earth from the International Space Station.
What is the mass of a Saturn V rocket?
2.75 x 10^6 kg Im doing an AP physics problem on it right now ^^
How do UV rays travel through space?
UV rays are a part of the electromagnetic spectrum, which includes light, radio, x-ray, infrared, and other "waves". All of these travel through space as photons. Photons behave both as particles and as waves. Their particle nature lets them travel through space, where there is nothing to conduct them, as a wave would normally need.
Where was the launch of the Apollo 11 at?
Apollo 11 was launched from the Kennedy Space Center in Florida, from Pad 39A.
What does super 150 mean in a suit fabric?
A fine suit is normally in the upper 80´s, upper 90´s. The numbers refer to the count, or fineness of the yarn used in the cloth.
A Super 120 is a beautiful made suit, but is pricy. A Super 150 is top of the line, and can be very expensive, indeed.
****************here is the correct answer please read******************
super any number means: how much 1 Grams of wool or any of that fabric will extend, means the smaller the number the heaver the fabric is, its not like a carpet thread roles.
# super 100 and below that is a heavy fabric and usually you want to use that suits in north America like Canada and north states in the U.S,
# Super 120 and above is light and you want to use that suits in the Midwest and California weather, don't be fool by the tag look into the shell fabric inside the suits and should tell you whats made of.
When was NASA founded and why?
NASA was founded on July 29, 1958, in response to the Soviet Union's launch of Sputnik, the first artificial satellite. The founding of NASA was part of the United States' efforts to assert its dominance in space exploration during the Cold War era.
What is there to explore in Space?
Space is endless and unbelievably interesting! Within our own solar system alone, there is so much to explore. We hardly know anything about our own planet; statistically, we know more about outer space than the floor of our own ocean. We know hardly anything about any of the other planets in our solar system; what their atmospheres are made of, if any of them harbor life, how old they are, what they're made of. Our sun is a mystery in itself too; the asteroid belt is full of millions of space particles that contain valuable information about the history of the universe. There's also an infinite amount of experiments to do concerning earth-based things in space; tons of potential cures for deadly diseases and opportunities for new inventions.
The stars are endless. There are so many that a pinhead held at arms length would cover billions of stars (not visible to the naked eye). Consider how many there must be in the universe! And then to think, many stars are actually whole galaxies. That means another trillion stars we can't even see on top of that. Every star probably has a dozen or so planets around it.
The numbers make a person feel so small. I don't think we're ever going to run out of things to study in outer space. Not for a long time.
How long a rocket takes to fly to outer space?
It takes a rocket about 15-20 minutes to reach outer space, which begins at the Kármán line located 62 miles (100 kilometers) above Earth's surface. The exact time can vary depending on the rocket's speed and trajectory.
Rather than using a pencil, astronauts needed a pen that would write while they were in space. So the pen was invented. On earth, they will write regardless of whether you are upside down or rightside up.
