This Olympics has been watched from all over the world – and beyond. Benefiting from a cloudless sky, this view of Londons Olympic Park was captured by the smallest imager aboard ESAs smallest mission: the High Resolution Camera on the Proba-1 microsatellite.

The Olympic Park, dominated by the circular Olympic Stadium, is visible towards the base of this 5 m-resolution image, with Victoria Park to its west and Hackney Marsh to the northwest.
This image was acquired by the High Resolution Camera (HRC). This black and white digital camera incorporates a Cassegrain telescope miniaturised to fit aboard Proba-1. Orbiting Earth at 720 km altitude, the entire satellites volume is less than a cubic metre.

HRC operates alongside Proba-1s larger CHRIS (Compact High Resolution Imaging Spectrometer) hyperspectral imager, which takes 15 m-resolution scenes across a programmable selection of up to 62 spectral bands, from a variety of viewing angles. This HRC image was acquired on 11 August.

About Proba-1

Operational for more than a decade, Proba-1 was the first in ESAs series of satellites aimed at providing in-orbit testing of new space technologies. Smaller than a cubic metre, Proba-1s many experiments include the compact HRC that acquires monochromatic images with an area of 25 sq km.

Proba stands for ‘Project for Onboard Autonomy – both cameras are largely autonomous. Controllers at ESAs Redu station in Belgium send up the location to be imaged – latitude, longitude and altitude – then the satellite itself does the rest, lining up its instruments with its target on the ground.

Proba-1 was launched in October 2001 as an experimental mission but is still going strong, having since been reassigned to ESAs Earth observation team. This year a software fix returned its radiation-damaged star trackers to full operations.

In November 2009 Proba-1 was joined in orbit by Proba-2, focused on solar monitoring. Proba-V, to monitor global vegetation, is due to launch next year.

LSNN is an independent editor which relies on reader support. We disclose the reality of the facts, after careful observations of the contents rigorously taken from direct sources, we work in the direction of freedom of expression and for human rights , in an oppressed society that struggles more and more in differentiating. Collecting contributions allows us to continue giving reliable information that takes many hours of work. LSNN is in continuous development and offers its own platform, to give space to authors, who fully exploit its potential. Your help is also needed now more than ever!

In a world, where disinformation is the main strategy, adopted to be able to act sometimes to the detriment of human rights by increasingly reducing freedom of expression , You can make a difference by helping us to keep disclosure alive. This project was born in June 1999 and has become a real mission, which we carry out with dedication and always independently "this is a fact: we have never made use of funds or contributions of any kind, we have always self-financed every single operation and dissemination project ". Give your hard-earned cash to sites or channels that change flags every time the wind blows , LSNN is proof that you don't change flags you were born for! We have seen the birth of realities that die after a few months at most after two years. Those who continue in the nurturing reality of which there is no history, in some way contribute in taking more and more freedom of expression from people who, like You , have decided and want to live in a more ethical world, in which existing is not a right to be conquered, L or it is because you already exist and were born with these rights! The ability to distinguish and decide intelligently is a fact, which allows us to continue . An important fact is the time that «LSNN takes» and it is remarkable! Countless hours in source research and control, development, security, public relations, is the foundation of our basic and day-to-day tasks. We do not schedule releases and publications, everything happens spontaneously and at all hours of the day or night, in the instant in which the single author or whoever writes or curates the contents makes them public. LSNN has made this popular project pure love, in the direction of the right of expression and always on the side of human rights. Thanks, contribute now click here this is the wallet to contribute
