How do scientists on communicate with spacecraft in space?
Scientists communicate with spacecraft in space using radio waves. Ground stations on Earth send commands to the spacecraft and receive data from it through radio signals. These signals travel through the vacuum of space to maintain communication with spacecraft regardless of their location in the solar system.
What is a way to make a homemade compass?
for this you need an iron pin, a magnet and a plastic cap that can float on water. Magnetize the iron pin by rubbing a magnet on it continuously in one direction for about 15 minutes. Now place the needle in the centre of the plastic cap and hold it in position with cello tape. take a container containing water and put the cap in it such that it floats on it. The pin will always point in north south direction. but the compass can be confused by a magnet placed near it.
How has the weather barometer changed?
The weather barometer has evolved from simple glass tube mercury models to digital and electronic versions that provide more accurate and detailed readings. Modern barometers offer features like trend indicators, historical data tracking, and connectivity to online weather services for more in-depth analysis. Overall, the advancement in technology has made barometers more user-friendly and reliable for forecasting changes in atmospheric pressure.
Why was the projector invented?
The projector was invented to display images or videos on a larger screen for a group of people to see simultaneously. It allowed for presentations, movies, and other visual content to be shared in an easily viewable format, making it a useful tool for education, entertainment, and business purposes.
How does the kaleidoscope work?
A kaleidoscope works by reflecting multiple mirrors and colorful objects inside a tube. When the objects shift, they create unique and symmetrical patterns due to the reflections. The patterns change as you rotate the tube, creating endless variations of colorful designs.
Plane mirrors are used in periscopes to enable viewing around obstacles, in optical instruments like microscopes and telescopes to direct and reflect light, and in security systems to monitor areas without being detected. They are also used in architecture and interior design to enhance lighting and create an illusion of more space.
Space technology is technology that is related to entering, and retrieving objects or life forms from space.
"Every day" technologies such as weather forecasting, remote sensing, GPS systems, satellite television, and some long distance communications systems critically rely on space infrastructure. Of sciences astronomy and Earth sciences (via remote sensing) most notably benefit from space technology.
Computers and telemetry were once leading edge technologies that might have been considered "space technology" because of their criticality to boosters and spacecraft. They existed prior to the Space Race of the Cold War (between the USSR and the USA.) but their development was vastly accelerated to meet the needs of the two major superpowers' space programs. While still used today in spacecraft and missiles, the more prosaic applications such as remote monitoring (via telemetry) of patients, water plants, highway conditions, etc. and the widespread use of computers far surpasses their space applications in quantity and variety of application.
Space is such an alien environment that attempting to work in it requires new techniques and knowledge. New technologies originating with or accelerated by space-related endeavors are often subsequently exploited in other economic activities. This has been widely pointed to as beneficial by space advocates and enthusiasts favoring the investment of public funds in space activities and programs. Political opponents counter that it would be far cheaper to develop specific technologies directly if they are beneficial and scoff at this justification for public expenditures on space-related research.
Do some rocket parts come off when the go it to space?
Yes, the booster rockets. This usually happens after their fuel has been spent, and they merely drop back to earth and land in the ocean where they are retrieved and used again for another flight.
Is there a Shadow the hedgehog movie being made?
So far there is no sign of that happening anytime soon.
The first satellite from earth name is?
The first satellite from Earth is named Sputnik 1, launched by the Soviet Union on October 4, 1957.
How do you install a standard sundial in the Southern hemisphere?
There is no such thing as a standard sundial.
For every different latitude (degrees north or south) the gnomon (the triangular shadow making bit) has to be cut differently.
If you live 30 degrees south, cut the gnomon to a 30 degree angle. Set up the sundial so the sharp end of the gnomon is pointing exactly North. The easiest way is to just twist the assembled sundial until it shows the right time.
If you want to be as accurate as possible you need to take longitude and time of year into consideration as well, but as most sundials are simply ornaments, that detail is not given.
"Award equator" does not have a standard or commonly recognized meaning in English. It is possible that this term is a typo or a specific term used in a particular context that is not widely known. Additional context or clarification would be needed to provide a more accurate explanation.
WHAT went into space on August 20 1977?
On August 20, 1977, the Voyager 2 spacecraft was launched into space by NASA. Voyager 2 was designed to study the outer planets in our solar system, and it has since gone on to become the only spacecraft to visit Uranus and Neptune. It continues to send data back to Earth as it travels into interstellar space.
What is the biography of jay miner?

How much does it cost to send something into space?
The cost of sending something into space can vary greatly depending on the size of the payload, the destination, and the method of transportation. On average, it can range from tens of millions to hundreds of millions of dollars for a single mission.
Where does data go after you delete it from the recycle bin?
When you delete data from the recycle bin, the operating system marks the space occupied by that data as available to be overwritten. However, until new data is written in that space, the "deleted" data may still be recoverable using specialized software.
The space race was fueled by the competition and fear between the U.S. and the Soviet Union during the Cold War. Both wanted to outdo each other in the field of space exploration to show their superiority and to ensure that they were more technologically advanced in case of an actual war.
