The most accurate and comprehensive stellar catalogues ever produced, the Hipparcos and Tycho Catalogues, were published in June 1997. Since June 1997 professional and amateur astronomers have been able to make use of this enormously rich resource on line.

ESA and NASA engineers, reasoning that over thenext two-to-three months the spacecraft's solar panels will increasinglyface the Sun and generate power, are continuing their efforts to contactthe Solar and Heliospheric Observatory (SOHO) spacecraft.Meanwhile, the ESA/NASA investigation board concentrates its inquiry onthree errors that appear to have led to the interruption ofcommunications with SOHO on June 25. Officials remain hopeful that,based on ESA's successful recovery of the Olympus spacecraft after fourweeks under similar conditions in 1991, recovery of SOHO may bepossible.

On 3 July the ESA Executive, the FIRST and Planck Principal Investigators (PIs), and the SPCdelegations met in ESA HQ. This was the first opportunity after the May SPC meeting to discuss sciencepayload and ground segment issues in the light of the decisions taken in that SPC meeting and therecommendations given by the FIRST and Planck science (instrument proposal) evaluation committees.

A more detailed report on the Huygens Automatic Gain Control (AGC) testis now available. The results of the test confirm that the Huygens Probehardware is in good health and that the depressed AGC values detectedduring the first two in-flight checkouts were the result of solar noise.

Rosetta Experiment Intermediate Design Reviews (EIDR) started at the beginning of July and will be finished in October. At the EIDRs the design of the individual experiments of the Rosetta payload are reviewed by ESA.

Engineers are continuing efforts to reestablish contact with the ESA/NASA Solar and Heliospheric Observatory (SOHO) spacecraft using NASA's Deep SpaceNetwork (DSN). Contact with SOHO was lost on 25 June (CEST) during maintenance operations.

At 01:16 CEST 25 June 1998 (23:16 UT 24 June), during routine maintenance operations, ground controllers lost contact with the SOHO (Solar and Heliosopheric Observatory) spacecraft and the satellite went into Emergency Sun Reacquisition (ESR) mode. The ESR mode is activatedwhen an anomaly occurs and the spacecraft loses its orientation towards the Sun. When this happens, the spacecraft automatically tries to pointitself towards the Sun again by firing its attitude control thrusters under the guidance of an onboard Sun sensor.

Following the ESA's Science Programme (SPC) meeting of 28/29 May "the coupled FIRST/Planck missions will now enter a detailed study phase, encompassing the selected instruments, with the objective of refining a joint mission scenario within reach of a stringent target cost", states Brian Taylor, Head of the Astrophysics Division of the Space Science Department of ESA, in ESA's Astronews No. 35.

Any scientists wanting to send instruments to the surface of the planet Mars have until 3 July to offer a small lander that might be carried aboard the European Space Agency mission Mars Express. The selection of a lander, if any, will then be the last stage in defining the scientific payload of Mars Express, which is intended to go into orbit around the Red Planet at the end of 2003. The choice of instruments for the orbiting spacecraft was recently ratified by ESA's Science Programme Committee. This month ESA is inviting tenders to build the spacecraft from three industrial competitors, Alenia/Aerospatiale, Dornier and Matra-Marconi, who have already studied the mission. The project must be fully defined in time for the Science Programme Committee to finally confirm Mars Express.

In a rare celestial spectacle, two comets have been observed plunging into the Sun's atmosphere in close succession, on June 1 and 2. This unusual event on Earth's own star was followed on June 2 by a likely unrelated but also dramatic ejection of solar gas and magnetic fields on the southwest (or lower right) limb of the Sun.
