India’s Mangalyan was sent to the Mars by launching it into a transfer orbit EOM around the sun. It leaves the earth at $\mathrm{E}$ and meets Mars at $\mathrm{M}$. If the semi-major axis of Earth’s orbit is $\mathrm{a}_{\mathrm{e}}=1.5 \times 10^{11} \mathrm{~m}$, that of Mars orbit $\mathrm{a}_{\mathrm{m}}=$ $2.28 \times 10^{11} \mathrm{~m}$, taken Kepler’s laws give the estimate of time for Mangalyan to reach Mars from Earth to be close to:
