Scientists at European Space Agency set for historic comet landing attempt

Scientists at European Space Agency set for historic comet landing attempt:

 A historic plan to land a space vehicle on a estraterrestrial body is poised to be set in motion Wed by scientists at the eu house Agency, despite a unpunctual drawback with the landing system.
It would be the climax of a decade-long mission to review a four kilometre (2.5 mile) wide lump of mud and ice referred to as 67P/Churyumov-Gerasimenko. it'll even be the top of the decade-long, 6.4 billion-kilometer (4 billion-mile) journey that Rosetta and its crony lander Philae traveled along to succeed in the estraterrestrial body.

ESA proclaimed late weekday that the active descent system, that uses thrust to stop the craft from bouncing off the surface, couldn't be activated. Instead, the agency is hoping on ice screws and a harpoon system to secure the lander.
"The cold gas thruster on high of the lander doesn't seem to be operating therefore we are going to need to believe totally on the harpoons at touchdown," same Stephan Ulamec, Philae Lander Manager at the DLR German part Center.
"We'll want some luck to not land on a boulder or a steep slope."

If all goes to set up, the laundry machine-sized lander can cut loose Rosetta at 0835 Greenwich Mean Time (3:35 a.m.) and drift right down to the estraterrestrial body, wherever it'll latch on mistreatment harpoons and screws. throughout the descent scientists are going to be overcome to try and do something however watch, as a result of the large distance to Earth — five hundred million kilometers (311 million miles) — makes it not possible to send directions in real time.
Confirmation of a landing, if victorious, ought to reach Earth by regarding 1603 Greenwich Mean Time (11:03 a.m. EST).

The set up is that Rosetta and Philae can then accompany the estraterrestrial body because it hurtles toward the sun and becomes progressively active because it heats up. mistreatment twenty one completely different instruments {they can|they're going to|they'll} collect knowledge that scientists hope will facilitate justify the origins of comets and different celestial bodies.
The European house Agency says that although the landing does not succeed, the 1.3 billion monetary unit ($1.62 billion) mission launched in 2004 will not be a failure. Rosetta are going to be able to perform eighty p.c of the mission on its own.
