Interstellar Mission You are on an interstellar mission from the Earth to the 8.7 light-years distant star Sirius. Your spaceship can travel with 70% the speed of light and has a cylindrical shape with a diameter of 6 m at the front surface and a length of 25 m. You have to cross the interstellar medium with an hydrogen atom/m3. (a)Calculate the time it takes your spaceship to reach sirius. (b)determine the mass of interstellar gas that collides with your spaceship during the mission. Note: Use 1.673 x 10-27 kg as proton mass. Problem A.2: Time Dilation Because you are moving with an enormous speed, your mission from the previous problem Al will be influenced by the effects of time dilation described by special relativity: Your spaceship launches in June 2020 and returns back to Earth directly after arriving at Sirius. (a) How many years will have passed from your perspective? (b) At which Earth date (year and month) will you arrive back to Earth?
