Hubble's solar arrays - behind the scenes [heic0203]
The power for Hubble's scientific discoveries comes from solar cells. Designing and constructing Hubble's first two sets of solar cell arrays constituted a huge technological achievement for the European Space Agency and European industry. After an in-orbit life of more than 8 years, this example of pioneering space technology was this morning (European time) replaced by new, more powerful arrays.

Student experiences fantastic start to Hubble Servicing Mission 3B
Amongst the assembled guests watching the launch of Space Shuttle Columbia this morning (11:22 UT) was one lucky Norwegian student. 17-year-old Arnt Ove Fordal won a trip to experience the earth-shaking launch of the Space Shuttle marking the beginning of Hubble Servicing Mission 3B.

European astronomers get their first chance to detect rocky planets around other worlds
Astronomers from ESA's Member States are preparing to take part in a French-led mission to be the first to search for rocky planets around other stars. The mission, COROT, is an important stepping stone in the European effort to find habitable, Earth-like planets around other stars.

Top class images help ESA's Rosetta prepare to ride on a cosmic bullet
Chase a fast-moving comet, land on it and 'ride' it while it speeds up towards the Sun: not the script of a science-fiction movie, but the very real task of ESA's Rosetta spacecraft. New observations with the European Southern Observatory's (ESO) Very Large Telescope (VLT) provide vital information about Comet Wirtanen - Rosetta's target - to help ESA reduce uncertainties in the mission, one of the most difficult ever to be performed.

Critical thermal tests begin for Rosetta comet chaser
With less than 11 months to launch, the most advanced spacecraft ever to visit a comet is about to begin a critical series of thermal tests at the European Space Research and Technology Centre (ESTEC) in Noordwijk, the Netherlands. These tests will play a vital role in ensuring the success of ESA's Rosetta mission to unravel the mysteries of Comet Wirtanen.

ESA scientist discovers a way to shortlist stars that might have planets
Markus Landgraf of the European Space Agency and colleagues (*) have found the first direct evidence that a bright disc of dust surrounds our Solar System, starting beyond the orbit of Saturn. Remarkably, their discovery gives astronomers a way to determine which other stars in the Galaxy are most likely to harbour planets and allows mission planners to draw up a 'short-list' of stars to be observed by ESA's future planet-search missions, Eddington and Darwin.

Hubble gets revitalised in new Servicing Mission for more and better science! [heic0202]
After nearly 12 years of incredible scientific discoveries, the ESA/NASA Hubble Space Telescope orbiting Earth is about to have another service visit. The purpose is to upgrade Hubble's systems and to install newer and more powerful instruments that will astoundingly increase Hubbles discovery capabilities and extend the longevity of the observatory.

First view of a newborn millisecond pulsar? [heic 0201]
Combining Hubble Space Telescope images with radio observations has revealed a highly unusual system consisting of a fast spinning pulsar and a bloated red companion star. The existence of the system is something of a mystery - the best explanation so far is thatwe have our first view of a millisecond pulsar just after it has been 'spun up' by its red companion star.

ESA Director of Science visits Applied Physics Laboratory
Following the disappointing outcome, for science funding, of the recent ESA Council of Ministers, the ESA Executive is exploring all avenues of increasing the science throughput of the ESA Science Programme against a continually declining budget.

Europeans invited to participate in Solar Dynamics Observatory
The European Space Agency (ESA) and NASA are collaborating on the 'International Living with a Star' (ILWS) programme that will study the behaviour of the Sun and its effect on our planet. European involvement is now solicited, in particular at payload level, for the first NASA contribution to the LWS programme: the Solar Dynamics Observatory. Notice of Intent is due by 20 February 2002, with proposals due by 24 April 2002.

When did liquid water fill the planets? Maybe not as early as was thought...
Planet-like bodies with liquid water formed very early in the history of the Solar System, or so scientists used to think. That scenario may now be due for revision after a finding with ESA's Infrared Space Observatory, ISO.

A New Year message from the Director of the Science Programme of ESA
Dear Colleagues,The year 2001 has been a transition year in the real meaning of the word. There were no launches this year. However four missions (INTEGRAL, Rosetta, SMART-1, Mars Express) are currently being prepared and will be launched within the next 18 months. The industrial contract for Herschel-Planck was signed. At the same time we started preparatory work on several missions selected in late 2000, Gaia, Solar Orbiter, BepiColombo, NGST, LISA and Eddington, as well as a crash exercise to look at a re-use of the Mars Express bus, (Venus Express).

ESA's new camera will revolutionise the way astronomers observe the Universe
Scientists at the European Space Agency have developed a new camera that is poised to revolutionise the way astronomers observe the Universe. Called S-Cam, the new device's capabilities read like an astronomer's wish list. From now on, astronomers will know almost everything about starlight from one simple observation.

Inter-Agency Consultative Group returns to its birthplace for twentieth anniversary celebrations
From 10-12 January, the Inter-Agency Consultative Group for Space Science (IACG) will celebrate its 20th anniversary in Padua, Italy. Founded in September 1981 with the aim of coordinating research activities for the four main space science programmes - those of Europe (ESA), the United States of America (NASA), Russia (Rosaviakosmos) and Japan (ISAS) - this 21st IACG meeting will discuss the coordination of projects related to Solar System exploration.

SOHO's private view of a sunbathing comet
You could see it easily with your unaided eye (but don't try!) if only Comet Machholz 1 were not so very close to the Sun. This unusual comet, reputed to flare up a lot, is today sweltering only 18 million kilometres from the Sun. This is its closest approach on an orbit that brings it back to the solar vicinity every 63 months. The best and perhaps the only view of it at this time comes from the ESA-NASA sunwatching spacecraft SOHO.

SOHO sees dazzling eruption from the Sun
The New Year got off to a striking start for scientists at SOHO's operations centre who were treated to a dazzling display from the Sun on 4 January. Images of an unusually beautiful ejection of solar material were captured by several instruments on the ESA-NASA spacecraft.

2003 missions will go to Mars with Christmas spirit
In two year's time, the planet Mars will receive a Christmas present from planet Earth - a flotilla of spacecraft. Gifts from different nations, the spacecraft will share communications channels to solve a problem which will intensify as Mars exploration gathers pace: how to relay the data gathered by so many missions back to Earth.
