Contract signed for Rosetta deep space communications
Returning a stream of data while flying alongside a comet almost 900million km from Earth requires a particularly sensitive and reliablecommunications network. The European Space Agency has recently signed acontract which should ensure that the vital information returned by theRosetta spacecraft during its long journey through the Solar System willsafely reach the eagerly waiting scientists.

PR 33-1998: SOHO pointing at the Sun again
The SOHO solar spacecraft yesterday, 16 September 1998, obeyed commands that turned its face fully towards the Sun. For the first time since 25 June, when SOHO spun out of control and communication was lost, it points the right way. The SOHO flight operations team reported success in the manoeuvre, which is called attitude recovery, at 18:30 UT on 16 September 1998.

INFO 30-1998: ESA presents INTEGRAL
Deciphering the processes of the Universe's alchemy which fabricate the elements of stars and galaxies, as well as theendpoints of stellar life, will be the tasks of ESA's INTEGRAL satellite, the INTErnational Gamma-Ray AstrophysicsLaboratory. Gamma-rays are a million times more energetic than visible light and bring us information from stupendousphysical events that made the universe habitable.A unique opportunity for journalists and cameramen to view INTEGRAL will be provided at ESA/ESTEC, Noordwijk,The Netherlands on Tuesday 22 September.

PR 30-1998: SOHO: on the road to recovery
Six days after receiving the first signal from the dormant SOHO Spacecraft, several blocks of telemetry data giving the spacecraft's on-board status were acquired late Saturday night, 8 August, at 23:15 hrs GMT. Further data acquisitions took place on Sunday 9 August and will continue in the following days."This is the best news I've heard since we lost contact with SOHO on 25 June" said Roger Bonnet, ESA's Director of Science. "I never gave up hope of some recovery of this fantastic mission. We should just hope that the damage sustained by SOHO's enforced period of deep freeze does not affect the scientific payload too much."
