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.
How long does it take to get to Mars? NASA's New Horizons probe is the fastest spacecraft launched from Earth as of January 2015. It traveled at 36,000 miles per hour when it was launched in 2006. If it had traveled to Mars during the closest approach to Earth, it could have arrived in as little as 39 days.
