Introduction to text about spacecraft measurements

Hi! I'm having some problems getting a good flow in my text. This is what I want to write. How can I give it a better flow?

Cassini is the first spacecraft dedicated to extensive and longterm in situ and remote measurements of the Saturnian system. The Cassini spacecraft has been orbiting Saturn since July 2004. The Cassini Langmuir probe, part of the RPWS instrument package, is still, to the date of writing, in a good state of health. This means that more than 12 years of RPWS/LP measurements of Saturn's space environment are available for analysis.

I tried many versions but it just doesn't sound good. =( Thankful for any help.

Hi Madelen,
Welcome to EssayForum :)

I would like to try to give my best in rephrasing or creating a good flow from the text that you have provided. I hope that this would be helpful for the development of your essay. You can see my alternative version below.

The first spacecraft called Cassini is dedicated to have extensive and long-term in situ including remote measurements of the Saturnian system. Moreover, this spacecraft has been orbiting Saturn since July 2004. It is fortunate that the Cassini Langmuir probe, part of the RPWS instrument package, is still in a good state of health up to now. Thus, it can be seen that more than 12 years of RPWS/LP measurements of Saturn's space environment had been available for further analysis.

Cheers :)
