On its journey to the solar, the Parker Photo voltaic Probe has a deliberate flyby of Venus. However to take action, a short, unplanned maneuver was required. Right here’s extra from NASA:
Working on preprogrammed instructions from mission management on the Johns Hopkins Utilized Physics Laboratory (APL) in Laurel, Maryland, Parker fired its small thrusters for 4.5 seconds, sufficient to regulate its trajectory by 77 miles and pace up – by 1.4 seconds – its closest strategy to Venus. The exact timing and place are crucial to that flyby, the sixth of seven approaches through which Parker makes use of the planet’s gravity to tighten its orbit across the Solar.
“Parker’s velocity is about 8.7 miles per second, so when it comes to altering the spacecraft’s pace and route, this trajectory correction maneuver could seem insignificant,” stated Yanping Guo, mission design and navigation supervisor at APL. “Nevertheless, the maneuver is crucial to get us the specified gravity help at Venus, which can considerably change Parker’s pace and distance to the Solar”.
