November 2010: The Odin satellite observes water in comet 103P/Hartley 2
 
The Comet Hartley 2 orbits the Sun with a period of 6.5 years. This year, it passed closest to the Sun on 28 October at 1.059 AU (Astronomical Unit = distance Sun-Earth = 150 millions km) and on 20 October, it was only at 0.121 AU from the Earth! An international team, with astronomers from Paris Observatory, took this opportunity to observe the fundamental line of water at 557 GHz with the satellite Odin. The comet produces 180 to 300 kg of water per second, and this production varies in time, certainly in phase with the rotation of the comet's nucleus.

February 2005: 4th anniversary of the ODIN satellite launch
 
You can see some of the scientific results obtained in aeronomy and in astronomy. You can also see the publications made about these two themes.
On the occasion of this fourth anniversary of the satellite launch, a press release has been written.
 
ODIN First Scientific Results
 

 

February 2001: First AOS spectrum in orbite.

Here's the first spectrum obtained with the AOS which shows the H2O spectra in the Earth's atmosphere.

Be careful, it's not a "scientific" spectrum because the telescope was pointing roughly in direction of the Earth's atmosphere and the amplitude measurement ("(ON-OFF)/OFF" ratio) haven't actual signification. The frequency calibration is also incomplete, because it lacks of orbital information.

Thus the spectrum shows that all works very well, with a base line very clean. The AOS is in excellent environmental conditions and the temperature regulation works well. The internal calibrations (frequency comb) show that the optical alignment is nominal.

Note that the rest of the radiometer works also very satisfyingly and that the satellite should provide very high quality Aeronomy and Astronomy measurements.
