Israeli technology enables images beamed from Mars

Fixed it now. In summary, the conversation discusses the use of advanced compression technology from three scientists at Haifa Technion to transmit high-quality images from NASA's explorer "Spirit" on Mars. This technology was developed by Technion graduates and has been praised for its efficiency and ability to maintain image quality despite the long distance between Earth and Mars. The article also mentions the use of a compression algorithm developed by the graduates' predecessors, which is currently the only space-qualified hardware for lossless compression.

It seems that Israel is again repaying US loans and grants with the lastest technologies.

Research by three scientists from the Haifa Technion made the transmission of video pictures from Mars by the NASA explorer "Spirit" possible, according to HP (Hewlett Packard) Labs, which was responsible for the image transmissions.

The ability to transmit the images was feasible thanks to a unique algorithm developed by Technion graduates living in the US as a continuation of work launched by two other Technion professors a quarter of a century ago.

Shortly after landing on the surface of the red planet earlier in the week, NASA's explorer began sending black-and-white photographs of Mars' rocky surface back to Earth, 106 million miles away. The sparkling clear images have been called "remarkable" by NASA officials and amateur astronomers.

The achievement was made possible by highly efficient data compression. "Because of the great distance between Earth and Mars, the signals are very weak, thus data can be transferred very slowly. Thus the way to speed it up is to compress the data and translate it into another form with many fewer bits without harming the quality of the image," Ziv explained. "NASA adopted the algorithm originally developed by our graduates, who are the second generation of our original work."

Didn't read the link, any info on how long a single pic takes with this data compression tech?

You should read the article which states the efficacy of their algorithms over the standard Rice algorithm.

The compression speed achievedis 1.33 Mpixels/second. Our algorithm yields about 15 percent better compressionthan the Rice algorithm. Currently, the only available space-qualified hardware designed forlossless compression is based on the Rice compression algorithm

Israel compression technology

Nice article, Onycho.
However, we also have some good American 'compression' technology right here on this forum. It's called the delete/edit button and allows you to compress two identical posts into one. :wink:

Thanks for the advice. I didn't realize that I had reposted by accident.
 

1. How does Israeli technology enable images to be beamed from Mars?

The Israeli technology used for this process is called a "compact spectrometer". It is a small, lightweight device that is able to analyze light and break it down into its different wavelengths. This allows it to capture images and data from Mars and transmit them back to Earth.

2. What makes Israeli technology different from other technologies used for space exploration?

The compact spectrometer developed by Israel is unique in its size and weight. It is small enough to be sent on space missions, making it more cost-effective and practical for space exploration. Additionally, it is able to collect a wide range of data, making it a versatile and efficient tool for studying other planets.

3. How long does it take for the images to be beamed from Mars to Earth using Israeli technology?

The time it takes for the images to be transmitted depends on the distance between Mars and Earth, which varies depending on the positions of the two planets. On average, it takes about 20 minutes for images to be beamed from Mars to Earth using Israeli technology.

4. What are the potential applications of Israeli technology for space exploration?

The compact spectrometer developed by Israel has a wide range of potential applications for space exploration. It can be used to analyze the composition of other planets, search for signs of life, and study the atmosphere of other celestial bodies. It can also be used for future missions to other planets, such as Mars, to gather more data and potentially even aid in human colonization efforts.

5. Is Israeli technology being used for any other space missions?

Yes, Israeli technology has been used for other space missions, including the Beresheet lunar lander mission in 2019. It has also been used for satellite missions to study other planets and for Earth observation. The compact spectrometer technology has proven to be a valuable tool for space exploration and is expected to be used for many more missions in the future.
