When unmanned spacecraft take
detailed photos of Mars, for example, the photos are transmitted through space
back to earth. These spacecraft produce low power transmissions that need to be
received on earth which is a long distance away, thus receiving such signals
requires farms of satellite dish antennas to make sure the signal, which is
only sent once, it received correctly and completely. The larger the image, the
more bandwidth and thus more antennas are required to receive the signals from
millions of miles away.
In an effort to best
compress the transmissions so no data is lost while at the same time requiring
less bandwidth and receiver antennas, NASA adopted algorithms developed by
graduate students at Israel's prestigious Technion, a university in Haifa,
which allows large photos to be sent in less time while using less resources,
thus allowing much higher resolution photos to be send back to earth than ever,
and more of them in the same time frame.
This
technology developed by Israeli students has enhanced science and saved NASA
billions of dollars while enhancing the scientific value of space
missions. |
