| Herschel Status Report - April 2010 |
Report for period 21 March to 21 April 2010 Mission operations of the Herschel space observatory continued nominally during the reporting period, with the spacecraft and subsystems all performing as expected. |

| No. 132 - Mission Operations Update |
Report for Period 27 March to 16 April 2010 The reporting period covers three weeks of Rosetta mission operations. Few instrument tests were performed in preparation of the active payload check-out (PC12), which will start in the next reporting period. The MIRO instrument was activated on 6 April for a validation of new on-board control procedures (OBCP) that apply a software patch. The ultra-stable oscillator (USO) of the Radio Science Investigation (RSI) was un-muted for a short period of time on 14 April. |

| Mars Express Status Report - March 2010 |
Main events and Activities On 3 March, Mars Express performed the closest ever flyby of Phobos, the larger of the two Martian moons. The spacecraft passed Phobos at an altitude of about 67 kilometres. The flyby was part of the Phobos flyby campaign, which started on 16 February and concluded on 26 March. The campaign, with a total of twelve flybys, provided a unique opportunity for scientific investigations of the small moon. Near the end of the campaign, on 21 and 22 March, spacecraft manoeuvres changed the Mars Express orbit to its planned final 88:25 resonance. This orbit resonance is more favourable for Mars observations by the optical instruments over the next few years of the mission. |

| No. 219 - Mission operations update |
| Report for Period 28 February to 27 March 2010 (week 9 - week 12)
The Venus Express spacecraft and instruments performed nominally during the reporting period. The atmospheric drag experiment (ADE) campaign #3a concluded on 28 February. On 20 March the regular DDOR measurements were performed. A solar array tilt experiment was carried out on 25 March around the pericentre passage. |

| No. 131 - Asteroid Lutetia flyby test |
Report for Period 27 February to 26 March 2010 The reporting period covers four weeks of Rosetta mission operations. These were dedicated to further payload maintenance activities and a rehearsal of the flyby of asteroid Lutetia. The rehearsal of the asteroid flyby dynamics went very smoothly and gives good confidence in the spacecraft behaviour for the actual flyby in July 2010. |
