What are some examples of rocket fuel?
Some examples of rocket fuels include liquid hydrogen, kerosene, liquid oxygen, and solid propellants such as ammonium perchlorate composite propellant (APCP) or solid rocket boosters. The choice of rocket fuel depends on factors like the specific mission requirements, efficiency, and safety considerations.
Is the only part of electromagnetic spectrum that the human eye detect?
No, the human eye can detect only a small portion of the electromagnetic spectrum, known as visible light. This spectrum ranges from wavelengths of approximately 400-700 nanometers, with colors like red, green, and blue falling within this range. Other parts of the electromagnetic spectrum, such as ultraviolet and infrared light, are invisible to the human eye.
How far does the exosphere reach?
The exosphere can extend up to around 10,000 km (6,200 miles) above Earth's surface. It gradually transitions into outer space and contains extremely low densities of gas molecules. The exosphere is where satellites orbit Earth.
How did apollo11 communicate with people on earth?
Apollo 11 communicated with people on Earth using a system of radio signals. The spacecraft transmitted signals to antennas on Earth, which were then decoded and relayed to mission control. This allowed astronauts to communicate with ground control and the world during the mission.
Who and when was the first living being on orbit?
The first living being in orbit was Laika, a Soviet space dog, who was launched on November 3, 1957, aboard the spacecraft Sputnik 2. Unfortunately, Laika's mission was one-way, as technology at the time did not allow for successful recovery of living organisms from orbit.
How much fuel does a rocket need to take off?
The amount of fuel a rocket needs to take off depends on its size, payload, and destination. However, rockets are designed to be as fuel-efficient as possible to maximize payload capacity and range. The fuel needed for a rocket launch is carefully calculated by engineers to ensure a successful mission.
How can you contact isro chief dr radhakrishnan?
You can contact ISRO through their official website or through their public relations office. It is unlikely that you can directly contact Dr. Radhakrishnan as he may have moved on from his role as ISRO chief.
Where did the first rockets come from?
The first rockets were likely developed in China around the 9th century AD. They were initially used for fireworks and signaling purposes before being adapted for military use. The technology then spread to other parts of the world through trade and warfare.
Robotic spacecraft are unmanned vehicles sent into space to explore celestial bodies, perform scientific research, or gather data. They are controlled remotely from Earth and equipped with various instruments and cameras to carry out their missions. Robotic spacecraft have been used to study planets, moons, asteroids, and other objects in our solar system.
Why has the antarctic region not been explored?
the climate of this region is very dangerous with hurricanes and blizzards blowing people who travel here can not bear the cold and often get the frost bite can be so sever los there limbs becaus of their extrme weather
There are more space technology spinoffs than people realize, and though most are used in Engineering, Industrial, and Scientific applications, but a few consumer applications that are more well known are:
Lithium Ion Batteries - not originally developed for NASA, but NASA funded further development to power the HST / ISS Pistol Grip Tool. The technology has found its way into the global marketplace.
Solid State Devices (SSD) - SSD technology was developed for the Hubble program. The original recording device on Hubble actually had magnetic recording tapes; the Solid State Recorder, developed in the early 90's and deployed on HST on the 1st Servicing/Repair mission, replaced the old recorder and is the foreunner of SSD devices. SSD technology is widely used today in Flash drives, SSD disk drives, etc.
Tempurpedic Foam (Memory Foam) - The Tempurpedic company is the only one that used NASA's technology for memory foam, using the patented NASA technology through NASA's partnership program. The material was specifically designed for use on Astronaut seats in the Shuttle.
Imaging Technology - CMOS sensor technology, widely used in digital cameras, medical scanners, and many other applications, was further developed for use on the Hubble Telescope. Imaging technology continues to advance as a result.
MARCbot - The MARCbot, currently used by thousands of soldiers in Iraq to locate IED's, was significantly upgraded by NASA engineers, improving its capability, mobility, and cost per unit.
You can view many of the hundreds of spinoffs at NASA's Spinoff site - the link is below.
When was the first cipher sent?
The first known use of a cipher dates back to the time of Julius Caesar in around 58-50 BCE. This cipher, now known as the Caesar cipher, involved shifting each letter in the alphabet by a fixed number to encode messages.
How far into space has the sent unmanned spacecraft?
The furthest unmanned spacecraft is Voyager 1, which has reached the edge of the heliosphere, the outer boundary of the Sun's influence. It is currently more than 14 billion miles (22 billion kilometers) away from Earth.
Well, once you get in space, all you see is a MILLION of stars. You would also see just a dark, black sky that stretches a long way in space. You might see Earth, too, plus the Moon probably. I would be really scared if I went up in space. But it's pretty amazing just to stare at all the stars and planets around you. :)
Has anyone seen silver balls in the sky?
Why yes, yes I have, funny uh? On several different occasions from around 1996 to around 2008. Only one each time and around in the same coordinates during the day moving like it knows I notice its presence. Never staying visual long enough to study much and almost always vanishes within it self. So.... ? yeah I would like to know more about this unusual phenomenon that perplexes my very being, anytime I think of it.
Why is Dr Robert Thirsk well known?
Dr. Robert Thirsk is well known for being a Canadian astronaut who made history by becoming the first Canadian to fly two space missions. He has spent a total of 206 days in space across his missions on the Space Shuttle and the International Space Station. Thirsk's contributions to space exploration and science have made him a respected figure in the field.
Should space exploration be justified?
Yes, space exploration is justified for several reasons. It can lead to scientific advancements, technological innovations, economic benefits, and a better understanding of the universe. Additionally, it can inspire people and serve as a symbol of human curiosity and ingenuity.
What year was Gemini 6 and 7 launched?
Gemini 6 was launched on December 15, 1965, and Gemini 7 was launched on December 4, 1965. Gemini 6 famously performed a rendezvous with Gemini 7 in space.
Is it possible to get parts for a mit18 space heater?
It may be possible to find parts for a MIt18 space heater, but availability will depend on the manufacturer and age of the unit. You can try contacting the manufacturer directly or searching online for retailers that sell replacement parts for this specific model.
What is the first spaceship to be launched into space?
The first spaceship to be launched into space was Vostok 1, which was a Soviet spacecraft that carried Yuri Gagarin, the first human to travel into space, in 1961.
What do you know about space exploration?
Space exploration is the investigation of outer space using spacecraft like satellites, telescopes, and probes. It aims to study celestial bodies, phenomena, and the universe's origins to expand human knowledge and understanding. Agencies like NASA, ESA, and private companies like SpaceX are actively engaged in space exploration missions.
What is the name of the first space capsule in space?
The name of the first space capsule in space was Vostok 1, which was piloted by Yuri Gagarin on April 12, 1961.
What provides power to spacecrafts?
While in earths atmosphere, chemical rocketry provides the propulsion. Once the space craft is aloft and free from earth's gravity, it course and trajectory is powered by chemical reaction directed through nozzles. The internal power is provided by "fuel cell's" which is a different type of chemical reaction that provides a steady flow of electrical power for use in life support ,communications, computers, etc.
