The Cube Method. If you have a little bit of time on your hands, you can cut the stick(s) of butter into fourths and then cube into small pieces. The smaller the cubes, the quicker the butter will soften. Just leave them at room temperature for about an hour or until soft to the touch.
The first successful Venus flyby was NASAâs Mariner 2. This spacecraft was launched on August 8th, 1962 and made a successful flyby on December 14, 1962. So that calculates to 110 days from launch to arrival at Venus. The most recent spacecraft to fly to Venus was ESAâs Venus Express. It was launched on November 9th, 2005, and took 153 days to make the journey to Venus.
Artist's conception of Venus Express. Image credit: ESA. The first spacecraft ever launched towards Venus was the Soviet Venera 1 spacecraft. It was launched on February 12, 1961 on course to Venus. Unfortunately, scientists lost contact with the spacecraft on February 17th.ission controllers didnât get a chance to put in a course correction that would have directed it closer to Venus, so itâs thought to have passed within 100,000 km of the planet on May 19th. Thatâs a total time of 97 days; just over 3 months. The first successful Venus flyby was NASAâs Mariner 2.
