Because you are moving with an enormous speed, your mission from the previous problem A.1 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 afer 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?

Captin Babena , depart the NASA Launch pad in a space shuttle that orbits Earth. As space shuttle accelerates to relativistic speeds, Captin Babena's thoughts turn to her twin sister, Saiena, who has never left Earth. They were born at exactly the same time. Will they still be the same age when babena returns from her triple?
Two radar pulses sent from the earth at 6:00 am and 8:00 am one day bounce off an alien spaceship and are detected on earth at 3:00 pm and 4:00 pm (but you aren’t sure which reflected pulse corresponds to which emitted pulse). Is the spaceship moving toward earth or away? If its speed is constant (but less than c), when will it (or did it) pass by the earth? (please draw a spacetime diagram.)
