Astronomers scramble to use INTEGRAL
The Call for Proposals to use guest observer time on ESA's forthcoming gamma-ray observatory has resulted in 291 individual proposals. These represent approximately 323 million seconds - more than 10 years - of observing time! This is 19 times greater than all the open time available during the first half of the nominal two-year mission.

INTEGRAL project forges ahead despite problems
With 460 days before the launch set for April next year, members ofthe INTEGRAL Science Working Team have met to review all issues ofESA's gamma-ray mission. Integration of the spacecraft is proceedingat Alenia, construction of the Proton rocket has started in Russiaand the science teams with instruments still to deliver are doingtheir utmost to overcome development difficulties and meet theschedule.

Olé! Spain delivers Integral's first science instrument
At a formal handover in Madrid on 10 October, ESA's Integral project has taken delivery the flight-model of the gamma-ray observatory's Optical Monitor Camera (OMC) from Spain's Instituto Nacional de Técnica Aerospacial (INTA). In two weeks, prime contractor Alenia will start installing the camera on the spacecraft. Integral's Proton launch is set for April 2002.

Observing with Integral
More than 80 astrophysicists from all over the world travelled to the small town of Les Diablerets in the Swiss Alps to learn how to use ESA's Integral satellite, once it is in orbit, to gather powerful gamma-radiation coming from distant objects in the Universe. A gamma-ray telescope is very different from a normal optical telescope. Thus special data analysis is needed to transform the signals measured by the scientific instruments on board Integral to fundamental physical units and images that describe the properties of the radiation entering the telescope

Integral ground control system successfully tested
How do you know that a satellite in space does exactly what you want it to do? You can't have a close look at the spacecraft once it has been launched. A thorough and systematic series of tests must therefore be carried out before launch to make sure that the commands will have the desired effect and that the data sent by the satellite are correctly interpreted. This is what experts at the European Space Operations Centre (ESOC) at Darmstadt are now doing with Integral, ESA's gamma-ray observatory.

Integral and Rosetta on show in Turin
In Turin today the Italian satellite builder Alenia Aerospazio presented two ESA spacecraft that will explore the near and far Universe: Integral, the gamma-ray observatory, will gather the most energetic radiation coming from distant objects. Rosetta, the comet chaser, will bring new insights in the formation of our solar system.

Integral Engineering Model test campaign successfully completed
On 23 August 1999 ESA's new gamma-ray observatory, Integral, has passed a most important milestone in its development. The Engineering Model tests, which lasted more than a year and which were to verify that all satellite subsystems and instruments interface well and function as a system, were successfully completed.
