Rosetta - ESA comet orbiter and lander

Euler · 2004-03-18 01:16:35

On March 2, the ESA launched [http://en.wikipedia.org/wiki/Rosetta_space_probe]Rosetta space probe. Its itinerary looks very impressive with 3 Earth fly-bys, 2 asteroid fly-bys, a Mars fly-by, and ending with a landing on a comet.

I had been reading about this one before. It uses a new drive system and has non-reflective silicon cells, it also has harpoons with internal ice screws.They have used a plan to use new types of propellant in these mission. I wonder if such robotics or these types of probe could be used for a mars mission, maybe also to explore phobos?

I think that this sort of tech is most useful in exploring the moons of Mars. It's a way to land on an object with minimal gravity where the probe is likely to float away unless anchored down.
I'd love to see a probed investigate the moons of Mars directly. There's all sorts of potential uses for the moons that would be made possible by a better understanding of them.

Cameras double as imaging cameras and star sensors.

A very long journey ahead...

http://www.spaceref.com/news/viewpr.html?pid=14850]Hey. THIS is the kind of "E-Z Bake Oven" I wanted as a little girl. :-\

*Is a Ptolemy instrument, "Evolved Gas Analyzer." Will also "smell" the comet for different substances. Weighs 4.5 kg and is about the size of a shoe box.

"One of the ingenious instruments on board Rosetta is designed to 'smell' the comet for different substances, analysing samples that have been 'cooked' in a set of miniature ovens."

I love this stuff.

At the end of the last New Norcia pass in the reporting period (DOY 324) Rosetta was at 49.8 million kilometres from the Earth. The one-way signal travel time was 2 minutes 46 seconds.

small Trajectory Correction Manoeuver of about 9 cms-1 on 25 November

Rosetta continues to fly in cruise mode which it entered 17 October. The AOCS gyro-less estimator was activated on 4 November and has been running since, outside the control loop for validation. This activity required an AOCMS patch in RAM to prevent incorrect use of gyro-less estimator output by the FDIR when the gyro-less and gyro-stellar estimators are ON in parallel. So far, the performance of the gyro-less estimator is good.

-YLR - Thanks for the link to the flash animation, at the end it says that in December 2015 Rosetta's journey will come to an end. However as it'll still be attached to the comet it's journey will be ongoing - we'll just miss it all! Amazing how many fly-bys its going to have though.

Info on the comet
http://www.esa.int/SPECIALS/Rosetta/ESA … 08D_0.html
67P/Churyumov-Gerasimenko is a large dirty snowball that orbits the Sun once every 6.6 years. Discovered by K. Churyumov, University of Kiev, Ukraine
& S. Gerasimenko, Institute of Astrophysics, Dushanbe, Tajikistan

During this time, it commutes between the orbits of Jupiter and the Earth. However, little is known about it, despite its regular visits to the inner Solar System.

Last report has it 6.73 million km from us. They're reporting a problem:

The boresight calibration of VIRTIS-H (VIRTIS - High resolution optical subsystem) on 16 March, for the third time did not succeed in determining the instrument boresight.
The PI Team is investigating the problem.

Hmmmmm. Otherwise Rosetta in excellent shape.

Interesting about the "Near Sun Hibernation Mode."

Status report
http://sci.esa.int/science-e/www/object … ctid=37699

18 Jul 2005 16:09
Report for period 24 June to 15 July 2005
The spacecraft is in active cruise mode. The reporting period covers the first active science phase of the mission, dedicated to the observation of the NASA Deep Impact probe's encounter with comet Tempel-1.
The spacecraft was slewed to point its remote sensing payload instruments towards comet Tempel-1 on 28 June. The comet was constantly tracked until 14 July, following a complex profile designed to satisfy the observation requirements of the four active instruments, ALICE, MIRO, OSIRIS and VIRTIS. Three of the remote sensing instruments were active continuously from 29 June to 14 July. VIRTIS was operated only for a few hours around the predicted time of encounter of Deep Impact with the comet, on 4 July. Daily passes were taken with the New Norcia station throughout the reporting period, to downlink the scientific data collected during the observations. An average of 60 Mbytes of data were produced and downlinked every day.
The observation campaign was very successful. All instruments operated very well and their science data were collected as planned and are undergoing the first analyses. A few problems occurred with the commanding timing of OSIRIS and with the MIRO instrument but could be recovered in both cases within about 24 hours, with minor impact on the overall instrument operations and data return. The exercise was the first scientific planning and operations scenario over large scale and an extended period of time for the Rosetta mission. It provided an important experience and a wealth of lessons learned which will be very useful to design the spacecraft operations around Rosetta's target comet 67 P/Churyumov-Gerasimenko.

*That's good to know. I especially liked the photo I kept in the quote box.

Must be fabulous to be part of the actual construction of a probe, though I'd rather be part of the monitoring team once it's launched and underway. :;):
