At 8 pm EDT today, MAVEN will be at a distance of 205,304,736 km (127,570,449 miles) from Earth with an Earth-centered velocity of 27.95 km/s (17.37 mi/s or 62,532 mph) and a Sun-centered velocity of 22.29 km/s (13.58 mi/s or 48,892 mph). We are now just 17 days from Mars orbit insertion on September 21st.
The spacecraft is currently at a distance of 4,705,429 km (2,923,818 mi) from Mars, and 215,446,454 km (133,872,220 mi) from the Sun. One-way light time to the #MAVEN spacecraft from Earth is 11 minutes and 24 seconds.
All navigation solutions continue to produce trajectory arrival predictions that ensure a successful transition to MAVEN’s required science orbit.
This is the sort of thing that we ought to be getting excited about. The MAVEN mission is awesome.
