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 and Planck will be launched together atop an Ariane 5 rocket in spring 2009.ESApod video programme

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 vital components in African food production. At the FAO Headquarters in Rome, Italy, satellite data are used to follow vegetation coverage and weather conditions virtually in real-time. That gives scientists a valuable forecasting tool and to some degree, an early-warning system. In addition, at ESA's Centre for Earth Observation just outside Rome, satellite data are being used to map vegetation coverage on an unprecedented scale. This map provides the FAO and the UN with a precise and up-to-date view of global vegetation coverage.ESApod video programme

On 25 and 26 November in The Hague, Ministers in charge of space activities within the now 18 ESA Member States and Canada meet to define the role of space in delivering Europe's global objectives. In a dedicated interview, ESA Director General Jean-Jacques Dordain explains the situation in space today and tomorrow and what ESA proposes in front of the current context of economical crisis. Jean-Jacques Dordain defines the priorities for Europe in space, talks about new programmes and how ESA will evolve.ESApod video programme

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 launch starting in 2015. Understanding the nature of dark matter, bringing back samples of an asteroid, returning to the moons of Saturn or Jupiter, and establishing whether life existed on Mars, are difficult choices with budgets that are not indefinitely expandable. Priorities have to be set, responsibilities shared, and work must be done in international teams. In pursuing its Space Science effort, Europe is consolidating its technological know-how in many, often unrelated disciplines. The spirit of adventure and exploration also fires the imagination of youngsters, prompting their interest in science.ESApod video programme

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 allow for atmospheric re-entry, bringing down to the Earth first some cargo and then in the future a complete crew. ESA and its industrial partners will have to develop new technologies to satisfy other crucial requirements, such as the ejection system to ensure the absolute safety of a space capsule’s crew in case of an anomaly on the launch pad or during its ascent phase.ESApod video programme

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 series of Earth monitoring satellites called Sentinels. The Sentinels are five families of satellites that will monitor the land, oceans, ice and atmosphere for markers of environmental change. Data from the Sentinel satellites as well as other ESA and non-ESA missions contributing to GMES will be combined with measurements taken on Earth. As changes in parameters such as air quality and ocean height are recorded over time, legislation can be put in place to tackle issues such as flooding, deforestation and drought.ESApod video programme

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 improving global communications, navigation and Earth observation. By developing this satellite infrastructure, ESA will improve many key services, such as the monitoring of earthquakes, forest fires and floods, aircraft navigation and the observation of sea-ice zones. On-demand satellite data will be available at the right place and at the right time – improving and even saving lives.ESApod video programme

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 performs the step that forms the bridge to future developments. The two-hour IXV mission is scheduled for launch in 2012 on board Vega, Europe's new, small launcher.ESApod video programme

In May 2009, Belgian ESA astronaut Frank De Winne will fly together with Russian cosmonaut Roman Romanenko and Canadian Space Agency astronaut Robert Thirsk on a Russian Soyuz spacecraft to the ISS. His back-up for the trip will be Dutch ESA astronaut André Kuipers. De Winne’s role on board the ISS will be to carry out experiments for an extensive scientific European programme. He will also be operating the Station’s robotic arm and the Japanese robotic arm after the docking of HTV, the cargo module from Japan. In preparation for these activities De Winne has been going through an intensive and long period of training aimed at preparing him physically and practising the experiments he will have to carry out on board the ISS in microgravity.ESApod video programme

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 launcher for geostationary transfer orbit. PSLV has the performance level required to launch Chandrayaan-1 on its way to the moon. Sriharikota is like a real town. About 2000 employees are living on the island with their families.ESApod video programme
