SULIS Solar Science Mission

#1

Post by Graeme1858 »


Some interesting science here. Named after a Celtic goddess of the Sun, SULIS is a UK-led solar science mission, designed to answer fundamental questions about the physics of solar storms. The mission consists of a cluster of small satellites and will carefully monitor solar storms using state-of-the-art UK technology.

Yes indeed, to quote:

"Precision manoeuvring in formation-flying is a challenge for satellite constellations and is crucial for maintaining a functioning coronagraph in space. The coronagraph is essentially an artificial eclipse created by one satellite in a pair eclipsing the Sun with respect to the view of the other satellite. This eclipsing is required in order to block out the bright light of the Sun surface in order to detect and measure the properties of the faint light coming only from the corona."

and

"On the SULIS mission, one of the satellites in the formation-flying pair will be shadowed by the other, meaning that the partially eclipsed satellite will require some additional power. This will be done through a laser power exchange with the satellite that is in permanent sunlight in order to carry out all its functions."

Regards

Graeme

Very interesting and increasingly important to out satellite dependent communication and remote sensing operations.
