The European Space Agency's Philae lander provides made space history by successfully reaching the surface regarding comet 67P/Churyumov-Gerasimenko.The landing, which took position at 11: 03 a. m. ET, was combined with rapturous scenes at the particular ESA’s control room within Darmstadt, Germany.
Philae may be the first probe to land over a comet.
"This is really a big step for the human civilization, " said ESA Director General Jean-Jacques Dordain, on a press conference inside the Darmstadt control room.
Right before 1 p. m. ET ESA released a picture of the comet taken simply by Philae during its descent, once the lander was about 2 miles above this surface of 67P/Churyumov-Gerasimenko.
Earlier upon Wednesday, the ESA released the primary image of its Philae lander separating from your Rosetta mothership on it's ambitious mission toward this surface of comet 67P/Churyumov-Gerasimenko.
The separation, which took position around 4 a. m. ET, marked the start of the 7-hour journey to this comet’s surface. The Rosetta spacecraft and its particular Philae lander have been over a decade-long mission through the particular solar system to rendezvous with this comet.
The comet, which is all about 2. 5 miles wide, travels at increases to 84, 000 miles hourly.
The washing machine-sized lander was built to drift down to the comet in addition to latch on using harpoons in addition to screws. During the descent, scientists were powerless to accomplish anything but watch, because the vast distance toward Earth — 311 million miles — created it impossible to send instructions instantly.
“The harpoon is going decrease, we’re sitting on the surface area, ” said an ESA official from the agency’s control room, shortly soon after 11 a. m. ET.
Afterwards, however, Philae's telemetry data suggested which the probe experienced something of the bumpy landing.
Indications were which the spacecraft touched down nearly perfectly, save for an unplanned bounce, said Stephan Ulamec, head from the lander operation.
Thrusters that were used to push the lander onto the comet's surface, and harpoons that could have anchored it to the comet didn't deploy properly. Initial data from the spacecraft indicated that it removed off again, turned and then found rest.
"Today most of us didn't just land once; we maybe actually landed twice, " said Ulamac.
Scientists were still trying to totally understand what happened but so far most of the instruments are working fine as well as sending back data as anticipated, he added.
The plan is that Rosetta as well as Philae will accompany the comet because it hurtles toward the sun and becomes increasingly active because it heats up. Using 21 different tools, they will acquire data that scientists hope can help explain the origins of comets and also other celestial bodies.
The $1. 6 billion dollars mission launched in 2004.
