Herschel and Planck
[LESS INFO] 30 VIEWS | ADDED 14:00:00 12/11/08
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.

Food and satellites: Keeping an eye on food production
[LESS INFO] 9 VIEWS | ADDED 12:00:00 12/02/08
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.

ESA Science: past and future
[LESS INFO] 11 VIEWS | ADDED 06:00:00 11/21/08
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.

ATV, the next step
[LESS INFO] 6 VIEWS | ADDED 15:00:00 11/20/08
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.

GMES – video news release
[LESS INFO] 12 VIEWS | ADDED 08:00:00 11/18/08
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.

The European Data Relay Satellite System – EDRS
[LESS INFO] 11 VIEWS | ADDED 13:00:00 11/07/08
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.

IXV: learning to come back from Space
[LESS INFO] 11 VIEWS | ADDED 08:00:00 11/05/08
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.

SHAR: the Indian launch base
[LESS INFO] 9 VIEWS | ADDED 11:00:00 10/21/08
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.

India – Europe cooperation
[LESS INFO] 7 VIEWS | ADDED 14:00:00 10/20/08
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 enter a new stage with its first lunar mission Chandrayaan-1. The large antenna designed by the Indian Space Agency and specially installed outside Bangalore to monitor the Chandrayaan-1 mission forms part of India's deep space network and is a good illustration of India's desire to play a role in the conquest of space and to offer its services to other countries. India is also interested in other forms of cooperation that go beyond lunar discovery and astronomical missions.

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 Chandrayaan are the result of international cooperative efforts, three of them with the European Space Agency (ESA). For ESA, Chandrayaan also represents an opportunity to re-use improved versions of the instruments which studied the moon on its SMART-1 lunar mission, and also a chance to send in orbit new instruments which will be used in upcoming ESA missions, such as the BepiColombo mission to Mercury.

Rosetta: rendezvous with an asteroid
[LESS INFO] 8 VIEWS | ADDED 11:00:00 09/04/08
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 encounter, and all the probe's science instruments will be active at some point in the fly-by. Reception of the first images is expected at the European Space Operations Centre some two hours after the encounter on 5 September 2008.

GOCE
[LESS INFO] 15 VIEWS | ADDED 09:00:00 09/01/08
ESA's GOCE mission is dedicated to measuring the Earth's gravity field and modelling the geoid with unprecedented accuracy and spatial resolution. GOCE is the first in a series of research missions known as Earth Explorers. Driven by the needs of the scientific community, Earth Explorers will provide the data to help understand critical Earth system variables and put Europe in pole position on Earth observation in the coming years. GOCE is due for launch in September 2008 on a Russian Rockot vehicle – a converted SS-19 Russian Intercontinental Ballistic Missile – from the Plesetsk Cosmodrome in northern Russia. All the data collected by GOCE will go towards creating a global gravity-field map with a level of accuracy never before available. ESA has developed an internet interface that will make these data easily and quickly available to scientists and researchers.
