Rosetta close to Comet 67P: Gas jets finally slowing down comet slightly, says ESA
This is going to be a very exciting news for many space enthusiasts. Rosetta seems to be not just enriching our knowledge about space and comets, it is also keeping us guessing about its travel and the mystery that it can unravel.
Rosetta is behind a comet in the outer space and the whole thought of trying to nab an icy comet is so much enthusing for space enthusiasts that they are not tiring while talking about this comet or the Rosetta probe.
The comet in question is none other than the slow paced Comet 67P and the space enthusiasts are excited by this whole spectacle of the Rosetta probe approaching the Comet 67P and revealing more details about it.
Astronomers claim that the Comet 67P, would take 12.4 hours to complete one rotation in the circular path itâ€™s moving in. Meanwhile Andrea Accomazzo who is the flight director of Rosetta while talking about it says, â€œThe gas jets coming out of the comet, are acting like thrusters and are slowing down the comet.â€ European Space Agency gave some very interesting details about the Comet 67P. It is not a huge comet and it weighs around 10-billion tons and is 4-km size in width.
Astronomers and the people who control the Rosetta spaceship actually use the landmark-method on the comet to know exact details of its rotation. Late last year the controllers of the spaceship were very sure that cometâ€™s rotation period lengthen by 33 milliseconds per day. At present, the comet is approaching the Sun. Researchers claim that as much as it closes in on the sun, the amount of gas and dust being released by it is also going up substantially.
In the meantime while talking about the latest development Andrea Accomazzo says that the Comet 67P is not going to slow down in the near future. Nonetheless he hastens to add that the cometâ€™s current speed allows them achieve the great magnitude of accuracy in navigating the spacecraft around the comet. Astronomers claim that the spaceship has enriched their knowledge substantially and add that it moves like an orbit within 30 km distance from the comet. But now it has retreated from the comet as the gas and dust are being released. â€œThe aerodynamic effects are now more and more important. The jets are getting stronger and strongerâ€¦ To give you an idea, these gases come out of the comet for a few kilometers and are moving at 800 meters per second. We definitely have to take this into account. We are a big spacecraft with 64 square meter s of solar panels. Weâ€™re like a big sailâ€ adds Andrea Accomazzo.
