A human error in the commands sent to her caused her antenna to tilt at an angle of two degrees from the Earth. The radio antenna engineers of the deep space network in Australia will try to contact her

Engineers have solved the data problem on NASA's Voyager 1 - but there are still glitches

  • One response
It turns out that the fault lies in the fact that a certain device that is still working tried to transfer the data through the spacecraft's main computer, which has been malfunctioning for many years. The engineers found a way around this

They are powerful, they are the size of Australia and no one imagined them until a few years ago - what is the secret of the storms at the poles of the largest planet in the solar system?

For the past five years it has been circling Tzedek and transmitting to Israel a huge amount of photographs and information related to Tzedek. Since it has a large supply of fuel left, there are those who are thinking of extending its stay around Tedek. The intention is to study the large moons of the planet Io, Europa and Ganymede as well as the rings of Jupiter
Close-up of Arrokoth by New Horizons. You can see that the "snowman" consists of two separate objects connected by a thin neck. An accidental collision of two such objects would shatter them rather than join them; The new study explains how the said connection was made. Photo courtesy of NASA

Saturn's moon Enceladus. At the bottom of the picture is its south pole with the tiger stripes from which the water jets come out, arising from an ocean of liquid water hiding under an outer layer of ice. The new study indicates that this ice layer is much thinner than previously thought in the South Pole region, which could greatly aid a future research mission to the Moon.
