Updates Herschel & Planck News

[SiberianTiger]

Can anyone post a link to a high-res replay of the launch which would show the Ariane's flight beyond the point the BBC coverage ends, please?

Not what you want I'm afraid, but a bit longer (2.5mins), covers the boosters seperation.

If that was the only video feed available thats probably as good as you'll get, unless some local crew had other cameras there. Unlikely they would let any civilians get close though.

Don't know why they cut back to the control room every time it goes into cloud, very annoying.

Well, but I personally felt, the Arianespace stream was of a better quality than NASA TV, despite the really annoying directing. For the short time they broadcast, they also make a fair deal of effort.

No rocket visible means nothing to look at, I suppose. Or maybe we didn't notice something funny in the control room they tried to show us.

Thanks for the link, Notebook.

Their pictures are good, but they hop all over the place with their direction. At least they got rid of the wobbly web-cam they had nailed to a palm-tree right next to the rocket.

Working on my theory that there is nothing more interesting to a cameraman(tv anyway) than another cameraman, I was suspicous about the control room shot. Yes there's a cameraman, in shot, at the back! Wonder if they get in-shot allowance?

I'm wondering, what kind of elements are necessary to describe position of an object in Lissajous orbit around a Lagrange point?

Cartesian state vectors, I guess. Since the lissajous orbit around L2 is essentially a highly perturbed Heliocentric orbit, you can't really use Keplerian orbit elements.

Wow! That's stunning.

Cheers,

I imagine a set of coefficients to the applicable parametric equations, as well as a value of the free parameter for some epoch would provide a first order approximation: http://en.wikipedia.org/wiki/Lissajous_curve. Beyond that, I expect that a set of state vectors and numerical propagation would be what is actually used for the navigation.

The satellite was transmitting with about 35 W RF power in X-Band via the Low Gain Antenna from a distance of about 280 000 km from Earth.

Europe's new billion-euro Herschel space observatory, launched in May, has achieved a critical milestone.

19 June 2009
Herschel opened its 'eyes' on 14 June and the Photoconductor Array Camera and Spectrometer obtained images of M51, ‘the whirlpool galaxy’ for a first test observation. Scientists obtained images in three colours which clearly demonstrate the superiority of Herschel, the largest infrared space telescope ever flown.

The end of this combined exam? hopefully others will look after these.

5 July 2010
ESA PR-15 2010 ESA’s Planck mission has delivered its first all-sky image. It not only provides new insight into the way stars and galaxies form but also tells us how the Universe itself came to life after the Big Bang.

http://www.esa.int/esaCP/SEMF2FRZ5BG_index_0.html

I've renamed this thread, and suggest it be used for the updates for these two missions. If they start generating a lot of info, then they could be split.
