Hubble's Wide Field Camera 3 (WFC3) and Space Telescope Imaging Spectrograph (STIS) were pointed just off the southern limb of the moon to look for a cloud of vaporized material blasted into space by the successive impacts of the rocket booster and spacecraft. The WFC3 images do not show any evidence for a temporary exosphere resulting from the impacts.
Hubble's ultraviolet sensitivity allowed astronomers to look specifically for hydroxyl (OH) that would have been produced by vaporized material from the impact. The STIS and WFC3 looked for emission from OH which would have formed if water molecules had been thrown into sunlight and broken apart by ultraviolet radiation into hydrogen and hydroxyl.
"A preliminary analysis of the STIS spectra do not show any clear evidence for hydroxyl, but further analysis is needed," said Hubble co-investigator Alex Storrs. The Hubble team plans on further analysis of their data.
The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. Goddard manages the telescope. The Space Telescope Science Institute conducts Hubble science operations. The institute is operated for NASA by the Association of Universities for Research in Astronomy, Inc. in Washington, and is an International Year of Astronomy 2009 program partner.
