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.
It took 228 days to reach Mars, and took a number of photographs when it arrived. Mariner 6 was next, in 1969. It took slightly less time: only 156 days. Mariner 7 took 131 days, and Mariner 9 took 167 days. Mariner 9 was the first spacecraft to orbit around Mars. The spacecraft that was launched from Earth the fastest was NASAâs New Horizons, which left Earth in 2006 at a speed of 36,000 miles per hour (58,000 km per hour).
