Herschel and Planck
Herschel, the largest telescope ever launched, will study objects within and outside our Galaxy. It will be able to peer through clouds of gas and dust and observe stars as they form. Unlike Herschel, Planck will rotate continuously about its axis, scanning the whole sky to compile the most detailed and complete map ever of the Cosmic Microwave Background, or CMB. This CMB radiation is the relic radiation left over from the Big Bang, which occurred about 14 thousand million years ago. Herschel a...

Food and satellites: Keeping an eye on food production
Data on the climate and vegetation cover collected by ESA’s Earth observation satellites are proving to be an invaluable tool to fight food scarcity. With the aid of Earth observation data, the Food and Agriculture Organisation (FAO) of the United Nations state that, in Ethiopia there has been four successive years of increased cereal production. This shows that Earth observation data is leading to better understanding of the conditions that affect crops and grazing pastures, both fragile but vi...

ESA Science: past and future
Since the very first satellites carrying scientific instruments were launched, our understanding of the cosmos has improved. The Sun is studied to the core and, beyond our star, the Universe is becoming less obscure. Knowledge of the Universe relates directly to humanity’s future. Over decades, ESA’s science programme has been conducted with long-term vision and, on many occasions, in international partnerships. The Cosmic Vision initiative is now paving the way for future missions that will lau...

ATV, the next step
The successful docking of the European Columbus module and the launch of the Automated Transfer Vehicle have opened a new era for Europe’s presence in space with the aspiration to consolidate its independence. Now, ESA is working on a proposed programme to develop new versions of the Automated Transfer Vehicle (ATV). The projects ESA is considering are essentially based on a re-use of the ATV's service module and the replacement of the integrated cargo carrier with a re-entry capsule. This would...

GMES – video news release
Relying largely on satellite data, the Global Monitoring for Environment and Security (GMES) programme will provide accurate and timely data to better manage the environment, understand and mitigate the effects of climate change and ensure civil security. ESA is responsible for the Space Component of GMES. It will provide continuous, accurate satellite data from Earth observation satellites, like Envisat and ERS. As part of the GMES programme, ESA is also developing, building and launching a new...

The European Data Relay Satellite System – EDRS
The European Space Agency is developing a network of satellites – the European Data Relay Satellite System – that will use geostationary satellites to communicate with both ground stations and other satellites – whose lower orbits restrict the time that they can ‘see’ any one ground station. Allowing low-Earth orbit satellites to deliver data continuously, instead of storing it on board for transmission while overflying a ground station, will increase the timeliness with which we receive data im...

IXV: learning to come back from Space
After being launched into space, the IXV - or Intermediate eXperimental Vehicle - will return to earth as if from a low-Earth orbit mission, testing brand-new European atmospheric re-entry technologies during its hypersonic and supersonic flight phases. For ESA, the mission is essential to further develop critical technologies for future robotic or manned spacecraft. In the name Intermediate eXperimental Vehicle, the word intermediate means that the vehicle builds on earlier achievements and per...

SHAR: the Indian launch base
On the island of Sriharikota, 150 kilometres north of Chennai, India has based its launch centre SHAR, the Satish Dhawan Space Centre, named after the research scientist and former president of the ISRO, the Indian Space Research Organisation. At SHAR two launch pads have been built for the two rockets developed by India: the PSLV, a 4-stage launch vehicle using liquid and solid propulsion and able to launch one-tonne craft into geostationary transfer orbit and the GSLV, a 2-tonne capacity launc...

India – Europe cooperation
The first venture between India and Europe took place in the 1980s. In 1981, Europe's Ariane 3 rocket launched into space India's first geostationary satellite Apple. The cooperation continues today with India's lunar mission Chandrayaan-1. India's INSAT satellites were also designed for weather forecasting and Earth observation. Thirteen of them lifted-off with Europe's Ariane launchers. Today India has developed its own launchers at its Sriharikota base in the Bay of Bengal and is about to ent...

The Indian launch vehicle PSLV is now at its launch station at Shriharikota - nowadays Chennai - a small island 100 km from Madras in the Bay of Bengal. It is waiting for its passenger, the Indian spacecraft Chandrayaan-1, currently under preparation in Bangalore. Chandrayaan means ‘journey to the moon’ in Hindi. India has already built and launched many satellites but this is the first time that it will venture beyond the orbit of Earth. Six out of the 11 research instruments on board Chandraya...

GOCE launch campaign at Plesetsk
Since July 2008 the GOCE Earth Explorer satellite has been at the Plesetsk Cosmodrome in northern Russia. ESA’s Gravity field and steady state Ocean Circulation Explorer (GOCE) is a unique satellite that will map the Earth's gravity field for a better understanding of our planet. Although GOCE was due to lift-off in September 2008, launch has been postponed pending a technical issue on the Rockot launcher.ESApod video programme...

Rosetta
Steins is Rosetta's first nominal scientific target. Based upon ground-based observations, it has been classified as an 'E-type' asteroid, composed mainly of silicates and basalts, but its properties are not known in detail. For these reasons, it has been selected as one of the two asteroids that Rosetta will study, from among those that were within reach of the mission. The study of asteroids is extremely important as they represent a sample of Solar System material at different stages of evolu...

Rosetta: rendezvous with an asteroid
Asteroid Steins belongs to the rare, largely unknown intermediate E-class, very bright and probably with a much-weathered surface. Steins' orbit was only known from ground observations, so Rosetta is conducting Europe's first-ever optical tracking campaign, providing highly accurate position data to Flight Dynamics specialists who are planning a series of trajectory corrections for an accurate fly-by. For over a year, Rosetta scientists and leading asteroid experts have been planning this encoun...

Water
The search for water in space has been quite successful; traces of ice have been found on Mars and water vapour has been found in several places in our galaxy. Water vapour was also recently detected on a planet outside our Solar System for the first time. It was an important discovery, although the planet is far too hot to be able to support life. Heavy water, which is also found on comets, poses the question of whether we can trace the origins of the water on earth through the heavy water foun...
