Luna 1960B (E-3 series) was the third Soviet attempt to photograph the far side of the Moon. The first being the highly successful Luna 3 mission and the second being the unsuccessful Luna 1960A. It was launched on April 16, 1960. Luna 1960B was designed to duplicate the Luna 3 mission, but with higher resolution cameras and a closer approach to the Moon. Bulk silicate composition (estimated wt%) SiO2 44. ... Luna 3, an automatic interplanetary station of the Luna program, was the third spacecraft successfully launched to the Moon and the first to return images of the lunar far side. ... Luna 1960A (E-3 series) was the second Soviet attempt to photograph the far side of the Moon. ...
The mission was a failure. At lift-off the four strap-on boosters of the rocket ignited incorrectly, broke loose, and fired in random directions. The accident also caused damage to the launch pad. The launch pad refers to the facilities where rockets or spacecrafts liftoff. ...

The mission of the Soviet spacecraft Sputnik 25 was an attempted lunar soft landing, with the purpose of returning data on the mechanical characteristics of the lunar surface, the hazards presented by the topology such as craters, rocks, and other obstructions, and radiation, in preparation for future manned landings. ...
Luna 2 was the second of the Soviet Union's Luna program spacecraft launched in the direction of the Moon.
Luna 2 was similar in design to Luna 1, a spherical spacecraft with protruding antennae and instrument parts.
Luna 2 was instrumented with a three component fluxgate magnetometer, similar to that used on Luna 1, but with the dynamic range reduced by a factor of 4 to -750 to +750 nanoteslas (gammas) so that the quantization uncertainty was -12 to +12 nT.
