The first critical engine burn, on March 18, lasted 1,200 seconds. It raised their apogee from 134,000 to 240,000 kilometers. What followed, as detailed in earlier reporting, was the DRO-A and DRO-B satellites carrying out four further orbital maneuvers, gravity assists and additional trajectory corrections over the next four months to get the spacecraft on course for their intended lunar orbit.
The efforts ended on July 15, 2024, with the satellites safely in their predetermined orbits, having traveled around 8.5 million kilometers. The satellites appear to have traveled as far as over one million km from the Earth, allowing a low-energy capture and insertion into lunar orbit.
With the satellites in a lower orbit than expected and limited delta-V, they calculated a new trajectory to get the sats to the intended orbit, and it worked.
This some kerbal level spaceflight
It really is!
