Envisat prepares to start work


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: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
