Whakarāpopototia te tuhinga:  Ahakoa he aha te take i kohikohi ai ngā toka ā-ao iti i ngā piriona tau ki muri, kāore pea te ā-papa i te take. I kii nga kaiputaiao i tenei ra ko nga inenga i mahia e te kairangahau mokowhiti a Europi a Philae, i tau ki runga i te komete 67P i te marama o Noema, e whakaatu ana ko te uara o te komete kaore i te magnetized. Kua whakaaro ētahi kairangahau o te ao, tērā pea ko te āheinga te kawenga mō te whakarōpū, kātahi ka herea ngā toka ki roto i ngā toka nui ake i ngā wā o mua o te hanganga o te aorangi. He whakakotahitanga o ngā whakaahua e 18 e whakaatu ana i te mahi a te komete 67P/Churyumov-Gerasimenko mai i ngā koki rerekē i kitea i waenganui i te 31 o Hānuere (mō runga maui) me te 25 o Maehe (mō raro matau), i te wā i tawhiti ai te waka ā-ao ki te 30 ki te 100 km mai i te komete. Engari i roto i tētahi pepa i tāngia tuihono e te niupepa Science, ko te rōpū i arahina e Hans-Ulrich Auster i te Whare Wānanga Hangarau o Braunschweig, Tiamana, i mea ko ā rātou raraunga - i whai hua mai i ngā peke ohorere e toru i āhei ai a Philae ki te kohikohi i ētahi atu hua i whakaritea - kāore i te tautoko i tēnei ariā. 'Mēnā kua āta āta āta āta a te mata, ka tūmanako mātou kia kite i tētahi pikinga mārama i roto i ngā pānuitanga o te āpure ā-ira i a mātou e whakatata atu ana ki te mata,' e ai ki a Auster. "Mēnā he tohu a te kometa 67P/Churyumov-Gerasimenko mō ngā karihi kometa katoa, ka whakaaro mātou kāore pea ngā kaha ā-manatō i whai wāhi ki te kohinga o ngā kōhatu hanga aorangi nui ake i te kotahi mita te rahi". Ko Allan H. Treiman, he kairangahau matua i te Lunar and Planetary Institute i Houston, Texas, kaore i uru ki te rangahau, i kii ko nga hua e tohu ana ko etahi atu kaha te kawenga. Ko nga raraunga autō i mua (i runga) me muri (i raro) i te tukinga o te toka i waenga i te tuatahi me te tuarua o nga paanga. Ko te teitei i runga ake i te mata ka whakairohia ki runga i te tuaka x me te kaha o te mara aorangi i runga i te tuaka y. Ka whakatauritea ngā inenga (kaitiaki) ki tētahi tauira whakapae (raina mārō) e whakaaro ana he mata iti noa iho te ārai.
I whakaarohia ko te magnetism te kawenga mo te whakatikatika me te here i nga toka. Tērā pea i arahi tēnei ki ngā wāhanga tōmua o te hanganga o te aorangi, e ai ki ngā pūtaiao. Kaore nga hua a Rosetta e tautoko i te ariā na te mea kaore i te magnetized te pokapū o 67P.
