    What's Solar Conjunction, and Why Does It Matter? Because Mars and Earth will be on opposite sides of the Sun, communications between antennas on Earth and those on spacecraft at Mars are about to get much quieter for a few weeks.

    MAVEN currently has a periapsis (closest) altitude of 152 km and an apoapsis (farthest) altitude of 4,495 km. The orbital period of the spacecraft is 3 hours 39 minutes and the distance from Earth to MAVEN is 2.66 AU (398M km or 247M miles). One way light time is 22 min. 10 sec.
