Envisat prepares to start work

06.03.2002


Envisat’s ASAR fully deployed


Since its successful launch into sun synchronous orbit on the morning of the first of March, Envisat has been getting ready to start observing the Earth.

Its 70 m2 of solar arrays are fully deployed, thus enabling it to obtain power from the Sun, and the ASAR antenna is now extending to its full 10 m, ready for its deployment in space. This will bring to an end the Launch and Early Orbit Phase.

The next step is the Switch on and Data Acquisition Phase that starts today. One by one, each of the 10 instruments on board will be turned on during the next few days, the instruments calibrated and a first verification of the data carried out. These activities are essential to guarantee the quality of the data that ESA will provide to Envisat users.



This phase will involve more than 200 people, including ESA staff and scientists all over the world, and entail the use of ground calibrators, ships, buoys, planes or balloons. As soon as the calibration and validation activities are completed, the delivery of data to Envisat users will start, a process expected to commence in September this year.

Tonight it is the turn of the Ka-band antenna to be released. This antenna will be used to transmit data, via Artemis, to a ground station located at ESA/ESRIN in Frascati, Italy, to ensure that data will arrive in near-real time.

Would you like to know more about how the data supplied by the 10 state-of-the-art instruments on board Envisat will help to protect the Earth and how the instruments work? Do you know exactly where Envisat is at present?

Our new site Envisat Expected Results contains text, photos and videos. All this information should help to answer your questions as well as explain why scientists all over the world are eagerly awaiting the data that Envisat, ESA’s new Earth observation satellite, will soon provide.

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

What does it look like below the ice shelf of the calved massive iceberg A68?

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...

Im Focus: Coping with errors in the quantum age

Physicists at ETH Zurich demonstrate how errors that occur during the manipulation of quantum system can be monitored and corrected on the fly

The field of quantum computation has seen tremendous progress in recent years. Bit by bit, quantum devices start to challenge conventional computers, at least...
