Following the spectacular achievement of the first soft landing of a space probe on a comet on Wednesday, worries emerged about the actual safety of the lander due to glitches during touch-down.
On Wednesday, the European Space Agency achieved a historic space success when its Rosetta Mission launched the Philae lander 500 million kilometres away from Earth, which landed on Comet Comet 67P Churyumov-Gerasimenko.
However, the lander could not attach itself securely to the surface of the comet as its harpoons failed to fire, the space agency said.
The agency also soon found that the lander had in fact bounced twice off the speeding comet's surface.
"@Philae_ROMAP magnetic field analysis revealed 3 landings at 15:33, 17:26 and 17:33 UTC," the agency said on twitter.
Scientists worried that the first bounce could have sent the lander almost one kilometre high in space, and it would have taken two hours for it to land again.
However, the Philae lander, which has been talking to earthlings through an agency-controlled Twitter account, finally sent out a message on Thursday saying it had landed safely.
"Now that I'm safely on the ground, here is what my new home #67P looks like from where I am. #CometLanding," the Philae Lander tweeted.
