This update sent in this morning by LISA Pathfinder Spacecraft Operations Manager Ian Harrison at ESOC:

The evaluation of this morning’s main engine burn conducted by LPF – the first of the so-called apogee-raising manoeuvres (ARMs) – showed an error of less than 1% on the predicted ‘deltaV’ (change in speed). This is well within the expected performance of these ARM burns.

Five more ARMs before Escape to L1!
