...vanished eons ago. What happened to them? All the researchers agree that they must have been eroded away - perhaps by swirling dust storms, perhaps by a flow of Martian water. "In any event," conclude Anders and Arnold, "the crater density on Mars no longer precludes the possibility that liquid water and a denser atmosphere were present on Mars during the first 3.5 billion years of its history." If there was water, there may have been life. And if Mars once supported some form of life, it still...
Many CEA scientists now believe the explosion was touched up by liquid hydrogen which spilled while being fed into the experimental hall's bubble chamber. The CEA is considering requesting funds for a separate bubble chamber building on the grounds so that an accident would be much less destructive there than in the present hall. The chamber is now being re-assembled but will not be used by the Harvard-M.I.T. experimenters who being work in November...
...Collins, CEA assistant director and senior research fellow, said Tuesday that the bubble chamber, for safety reasons, probably will not be returned to the CEA experimental hall. The hall was devastated by an explosion July 5. Most observers, Collins said, now believe that the blast was touched off when liquid hydrogen being fed into the bubble chamber spilled onto the floor...
...rips through the experimental hall of the Cambridge Electron Accelerator, injuring eight Harvard and M.I.T. scientists and technicians and causing at least $1 million in damage. The explosion blew the roof off the circular experimental hall and severely damaged the bubble chamber then being filled with 100 gallons of liquid hydrogen...
JULY 7--Preliminary investigation indicates that 95 gallons of liquid hydrogen in the bubble chamber were expelled safely and that hydrogen in the chamber filling system may have caused the explosion...
