Re: Rosetta - ESA comet orbiter and lander

Rosetta report


for Period 9 December 2005 - 6 January 2006

http://sci.esa.int/science-e/www/obj...objectid=38558
...At the end of the reporting period (DOY 006) Rosetta was at 360 million km from the Earth (2.40 AU; one-way signal travel time was 20m 00 s). The distance to Sun was 262 million Km (1.75 AU).
Future Milestones
Preparation for the first Solar Conjunction continues. The spacecraft will be at an angular distance from the Sun below 5 degrees between mid March and mid May 2006, with a minimum separation angle of about 0.3 degrees on the 13 April.
Just before the start of the Solar Conjunction the third Payload Passive Checkout (PC2) will take place in March 2006.
After the Solar Conjunction the spacecraft will be configured into Near Sun Hibernation Mode for a period of about 2 months, from end May to end July 2006.
Operations for the Mars swing-by (February 2007) will start in August 2006....

Re: Rosetta - ESA comet orbiter and lander

Beautiful photo!

*Moon and Earth.  Taken during March 4 flyby of course.  Photo taken just 3 minutes prior to its closest approach to Earth.  Over Pacific Ocean west of Mexico.

Stunning.  smile 

Will fly past Mars in February 2007, and two more Earth flybys:  November 2007 and November 2009.

--Cindy

the Mars fly-by will be great !

Re: Rosetta - ESA comet orbiter and lander

First Solar Conjunction

19 Apr 2006 14:35
Report for period 10 March - 7 April 2006

The reporting period covers four weeks of cruise, in which the spacecraft was gradually entering the first solar conjunction of the mission. At the end of the reporting period the angular separation from the Sun was down to 1.04°.


http://sci.esa.int/science-e/www/object … ctid=39113


On 15 March the spacecraft was configured for solar conjunction, including the activation of the S-band transmitter in parallel to the nominal X-band link. On 30 March the telemetry bit-rate was reduced as planned to 3.5 kbps, to cope with the increasing signal disturbance from the Sun. On 6 April a telecommand link test was successfully performed, all commands were successfully decoded on-board, although the uplink signal as received by the spacecraft was significantly disturbed by the Sun.

Re: Rosetta - ESA comet orbiter and lander

Rosetta warms up for Mars swing-by

Rosetta will make its closest approach to Mars on 25 February when it will be just 250 km above its surface.

Close vicinity to the planet is essential for the spacecraft to make the most efficient use of the swing-by, however, this also makes the manoeuvre complex. This is why mission controllers at ESA's European Space Operations Centre (ESOC) in Germany are carefully monitoring the spacecraft's path in space and preparing to perform trajectory correction manoeuvres 16 and 7 days before Rosetta makes its closest approach to Mars.

Rosetta's close vicinity to Mars will also provide an excellent opportunity to take a close look at the planet. Using the on-board instruments both on the orbiter and the Philae lander, the Rosetta scientists will be able to calibrate their instruments and complement ESA's Mars Express data by carrying out a 'mini' observation campaign in the weeks around the Mars swing-by. Science operations will start at the beginning of January 2007 and be 'formally' concluded at the end of March.

Re: Rosetta - ESA comet orbiter and lander

Rosetta space probe just a stone’s throw away from Mars
The ESA-led unmanned Rosetta spacecraft launched to study two asteroids and one comet will do a Mars fly-by on February 25, 2007. Later, the spacecraft will do fly-bys of asteroid 2867 Šteins and asteroid 21 Luetia, and its lander Philae will land on comet 67P/Churyumov-Gerasimenko.

Media event at ESOC: closest encounter between ESA's comet chaser Rosetta and Mars
On Sunday 25 February, ESA's probe Rosetta, currently on a ten-year journey to comet Churyumov-Gerasimenko, will make its closest approach to the planet Mars, coming within 250 kilometres of its surface.

Re: Rosetta - ESA comet orbiter and lander

250 kms is very low, must be a fine balance between minimizing atmospheric drag and maximizing gravity assist.

Re: Rosetta - ESA comet orbiter and lander

Rosetta successfully swings-by Mars – next target: Earth

25 February 2007
At 03:57 CET today, mission controllers at ESOC, ESA's Space Operations Centre in Germany, confirmed Rosetta's successful swingby of Mars, a key milestone in the 7.1-thousand-million km journey of this unique spacecraft to its target comet in 2014.

The gravitational energy of Mars helped Rosetta change direction, while the spacecraft was decelerated with respect to the Sun by an estimated 7887 km/hour. The spacecraft is now on the correct track towards Earth - its next destination planet whose gravitational energy Rosetta will exploit in November this year to gain acceleration and continue on its trek.

Re: Rosetta - ESA comet orbiter and lander

Oh definetely - feels like something out of 2010 even.

Its not often we get to see spacecraft imagery like this save of the space shuttle/ISS, Apollo, or the various Mars landers.

I hope little Philiae will be able to give us some information on Mars.

Boosting The Accuracy Of Rosetta's Earth Approach
http://www.sciencedaily.com/releases/20 … 102623.htm
ScienceDaily (Oct. 19, 2007) — On October 18 at 18:06 CEST, the thrusters of ESA’s comet chaser, Rosetta, were fired in a planned, 42-second trajectory correction manoeuvre designed to 'fine tune' the spacecraft's approach to Earth. Rosetta is now approaching Earth for its second planetary swing-by of 2007.

Rosetta is going to be the first spacecraft to visit planet Mars and then planet Earth again

Could comets have brought water and organic materials to Earth?

Europe's Rosetta mission is on route to find out. The spacecraft swings by the Earth this month, gaining speed on its 10- year quest.

Thanks for the link Eurolauncher. One of the biggest problems with this mission is saying the name of the comet that will be visited smile

Re: Rosetta - ESA comet orbiter and lander

NASA fans should look out for the Alice, a spectrometer on ESA Rosetta's Orbiter. It was paid for by NASA is a derivative of the Pluto UV that NASA will use on NewHorizons. There were already joint campaigns between Rosetta and New Horizons. Using the instrument NASA should be able to see composition of Pluto's atmosphere, it has a pinhole aperture to shut down the intensity of sunlight without blinding NH's detectors.
