Watching the Deep Impact flyby of Hartley 2
Watch the Deep Impact flyby of Hartley 2 this instant (11:06 AM eastern)! The images are incredible. Update: The fly-by is over, but the live stream is still available (as of 11:30 am Eastern), showing some of the images taken. The comet itself is a peanut-shaped object about two miles long, with a jet of water coming out one end.

Overhaul of NASA’s Deep Space communication system completed
NASA has completed a significant upgrade of its Deep Space communication system. These unheralded antennas and the engineers who maintain them make it possible for scientists to communicate with the far flung planetary probes in orbit around Venus, Mars, and Saturn, as well as the spacecraft visiting comets or traveling beyond the edge of the solar system.
Opportunity’s journey continues
Opportunity’s long journey across the desert plains of Mars to reach Endeavour Crater is now more than half completed. Below is the most recent mosiac of its view heading east towards the crater, with the crater’s rim visible on the distant horizon, still five miles away.
UN conference passes broad ban on “geoengineering”
A UN conference in Japan today approved the extremely broad language that I had noted earlier this week, banning all “climate-related geoengineering activities that may affect biodiversity . . . until there is an adequate scientific basis on which to justify such activities.” You can read some reactions here. Key quote from the ETC group, a Canadian non-profit organization which supports the language:
The agreement, reached during the ministerial portion of the two-week meeting which included 110 environment ministers, asks governments to ensure that no geoengineering activities take place until risks to the environment and biodiversity and associated social, cultural and economic impacts have been appropriately considered. The CBD secretariat was also instructed to report back on various geoengineering proposals and potential intergovernmental regulatory measures.
If the broad language of this policy is accepted by the United States government, it will effectively shut down almost all new construction and development, as practically anything people do “may affect biodiversity.”
