Who made nomad desert explorer?
The Nomad Desert Explorer was made by the Australian company Bruder EXP-6. Its innovative design allows for easy off-road exploration and camping in remote desert areas.
How did they get the Space Station in space?
The International Space Station (or ISS for short) is like a puzzle or legos. It is put together, 1 piece at a time. In all, there are 100 major peices that the ISS is built of. The ISS is expected to be finished in 2011.
Why does the International Space Station require ammonia coolant?
Anhydrous Ammonia is used in passive cooling systems aboard the ISS, primarily in Ammonia Heat Pipes.
Liquid AA, when heated, turns to a gaseous state and draws heat along with it. It is put into a sealed aluminum pipe that has internal ridge veins running its length; as one end of the pipe is heated (e.g., by a power unit or computer), using a process of capillary action, it turns to a gas and moves to the other (cool) end of the pipe, drawing the heat with it. Once it gets to the cool end, it changes back to a liquid state and returns along the ridges to the hot end, completing the cycle.
Liquid AA is also used for air-conditioning, and its system is similar to the Ammonia Boiler System aboard the Shuttles. It's the same process, just a different type of system; ammonia is heated, turned to a gas, drawing the heat from the area and thus cooling the air.
The ISS uses ammonia heat pipe cooling systems for electronic systems, power units, internal cooling, etc. Systems are installed both inside and outside the station as well. The Hubble Telescope also uses ammonia heat pipes for electronics cooling, using a different method called a Capillary Pumped Loop. The system was designed to compensate for extra heat from new electronic systems that were installed on HST Servicing Mission 3A, used to save the NICMOS Camera experiment.
If you go to my bio page and scroll down toward the middle, you can see one of the large cooling panels (the largest in the world at the time) built for the ISS that I was responsible for, as well as the CPL panel for HST. The picture of the ISS Radiator panel has many yellow lines going across it - those are the heat pipes. The yellow tint is due to the adhesive glue sheets that were added prior to the top panel being installed. After that, the whole panel is covered in heavy mats and sealed, then put under extreme vacuum for pressure to keep everything together while being baked for many hours in a large oven. The ISS Radiator required an extremely large oven; the one that was eventually used was previously used for baking enamel finishes on cars.
Much smaller versions (essentially mounting plates with several pipes underneath) are used for electronic systems aboard the station.
The pictures of the smaller white panel being worked on, installed in the Shuttle Bay, and finally attached to the Hubble is HST's CPL Radiator Panel. It was installed during Servicing Mission 3A to help dissipate heat from new electronic systems that were installed at the time.
The ISS Radiator was eventually coated on one side with a diffused silver tape (literally silver), that covered one side, or 100 square feet. A diffusion pattern, etched into the tape, helps to diffuse reflected sunlight off of the panel to prevent blinding any astronauts working in space.
Each 25' roll of tape cost just over $4,000 in 1998; I'll let you do the math on how much it was per foot then, and contemplate how much it would be today with the increase in silver prices.
What is the most recent space mission that explored Saturn?
The most recent space mission to explore Saturn was the Cassini-Huygens mission, which ended in 2017. Cassini was a spacecraft that orbited Saturn for over 13 years, studying the planet and its moons in great detail. The mission provided valuable insights into the planet's atmosphere, rings, and moons.
What does a international space station look like from earth?
The International Space Station (ISS) appears as a bright, fast-moving dot in the sky when viewed from Earth. It resembles a fast-moving airplane but does not have blinking lights. The ISS orbits the Earth approximately every 90 minutes, so it can often be seen during evening or early morning hours.
What are the 2 space shuttle disasters?
The two space shuttle disasters were the Challenger disaster in 1986, when the shuttle broke apart 73 seconds after launch, and the Columbia disaster in 2003, when the shuttle disintegrated upon re-entry into the Earth's atmosphere. Both tragedies resulted in the loss of all crew members on board.
What country launch the skylab in 1973?
The United States launched Skylab, its first space station, in 1973. Skylab was launched by NASA atop a Saturn V rocket.
Can Space shuttle launching cause earthquakes?
No, there is no way for a shuttle launch to cause an earthquake. They are very loud, but while they are close to the ground, a huge amount of water is poured under the flame. The white you see is steam, not smoke! This water keeps the rocket from destroying its pad, let alone causing earthquakes!
What moves faster a spaceship or a space station?
A spaceship typically moves faster than a space station. Spaceships are designed for interstellar travel and can reach high speeds to explore different regions of space, while space stations are usually in orbit around a celestial body and travel at a slower, consistent pace.
Why NASA's space program should be funded by the government?
NASA was created by Congress and and operates under a Federal Statute (law). A common misconception is that it is a large agency and its operations are performed by NASA employees. In fact, NASA is a relatively small organization, and the bulk of its centers and operations are performed by civilian Aerospace contractors. The debate on "privatizing" NASA is ridiculous, since private companies essentially run the space program anyway. NASA just administers it.
The Space Program is only one of NASA's functions; by law, its mandate is to oversee the space program, as well as aeronautics and aerospace research.
In 1998 to continue photographing the moon collecting data nasa launched?
The Lunar Prospector was launched by NASA in 1998 to study the moon's surface composition, gravity, and magnetic fields. It helped gather valuable data on the presence of water ice on the moon's poles and provided insights into its geological characteristics.
NASA is planning to send humans back to the Moon through the Artemis program, with the goal of establishing a sustainable presence by 2024. They are also working on developing new technologies for robotic exploration of Mars and beyond, with the long-term goal of sending astronauts to Mars.
How is space technology used on earth?
Space technology is used on Earth for various purposes, including weather forecasting, communication (satellite phones, GPS), monitoring natural disasters, agricultural management (crop monitoring), environmental monitoring (climate change), and scientific research. Space technology also enables us to explore and understand our planet better.
Where is NASA's Marshall space flight center?
NASA's George C. Marshall Space Flight Center is located in Huntsville, Alabama. It is NASA's Center of Excellence for research in civilian rocketry and spacecraft propulsion.
What countries where involved in building of the ISS?
The countries involved in building the International Space Station (ISS) include the United States, Russia, Japan, Canada, and 11 countries from the European Space Agency. Each country contributes different components and expertise to the construction and maintenance of the ISS.
How does the space station not run out of air?
The International Space Station generates oxygen through electrolysis, which splits water into oxygen and hydrogen. Carbon dioxide is removed from the air by a system called the Carbon Dioxide Removal Assembly, which uses a chemical sorbent to trap carbon dioxide. These systems work together to maintain the air supply on the space station.
How many times has the space shuttle launched from earth?
As of the 10th of April 2010, there have been 131 space shuttle launches.
What was the name of the first shuttle launched after challenger?
The first shuttle launched after the Challenger disaster was the Discovery shuttle, which returned to space on September 29, 1988. Discovery's mission, STS-26, was considered a success and marked the resumption of shuttle flights after a 32-month hiatus.
How long will a foot print last on the moon?
We can't be absolutely sure how long a footprint will last on the moon since it might or might not be struck by a meteoroid or other cosmic debris, but potentially it could last for billions of years. It is also possible (although I am not expecting it) that the moon will someday be colonized by people, who will then disturb the existing footprints. But then again, they might want to preserve them as monuments.
What are scratch resistant lenses used for in space?
They're not - DLC (Diamond-like Carbon) coatings are used as spacecraft coatings to make them more resistant to the harshness of space environments. The DLC technology was further developed by Diamonex Corp. into scratch resistant lenses and other similar spinoff technology.
Were there any tragedies in the shuttle program?
Yes the Shuttle Columbia, suffered a great tragedy in 2003 and the Shuttle Challenger was lost to an explosion after launch in 1988. Columbia was one of the first shuttles and made over 20 trips to space. She was a great ship. R.I.P Cosmonauts.
