The Terrestial Planet Finder gets the axe, now...
(Basic translation) "Don't even THINK about it, we want someone to play golf on Mars by 2030, damn it!". --- Water Discovery May Not Spur Space Mission LOS ANGELES - To scientists scanning the cosmos for signs of life, the stunning discovery of what appears to be water on an obscure moon orbiting Saturn couldn't come at a more pivotal time. With a fresh focus on returning astronauts to Earth's own moon, NASA has squashed several missions that over the next decade were to have continued the search for extraterrestrial life. Can images from Enceladus, an icy moon located more than 800 million miles from Earth, supercharge interest and funding for life-finding missions? Probably not any time soon. Missions take years to launch and what enthusiasm NASA has for finding otherworldly life already is focused on Mars and the Jupiter moon Europa, where promising leads have been studied for years. Even those missions aren't on the fast track. Budget woes last year scrapped a NASA project to send a nuclear-powered spacecraft to Europa, which may hide vast oceans of water under thick ice sheets. The cancellation of a trip to a moon more accessible and hundreds of millions of miles closer than Enceladus doesn't bode well for new projects. "Anyone who thinks they can squeeze an Enceladus mission into the budget planning is awfully naive," said Bruce Jakosky, an astrobiologist at the University of Colorado, Boulder. Still, scientists were abuzz over a report last week in the journal Science that showed what seem to be water geysers shooting miles above Enceladus' warm southern pole region. Along with a stable heat source and organic substances, water is believed essential to life. The tantalizing Enceladus images were snapped by the Cassini spacecraft, an international project managed by NASA's Jet Propulsion Laboratory in Pasadena. Cassini plans at least one more pass by Enceladus, in 2008, which could reveal further details of the moon's potential to harbor life - though not the presence of life itself. The space agency hasn't ruled out extending that mission, said Andrew Dantzler, director of NASA's solar system division. But any future mission to Enceladus would come after a Europa trip, he said. "I believe all these great missions that we want to do, we will do," he said. "We just have to space them out." Extraterrestrial organisms likely would be simple microbes capable of surviving extreme conditions. Not the stuff of movies, but enough to keep some NASA space prospecting programs alive amid the agency's goal of revisiting the moon by 2018. NASA's proposed budget for fiscal year 2007 would give science projects $5.3 billion, but plans are to limit growth over the next four years to compensate for a $3 billion shortfall in the space shuttle program. Two programs to search for planets beyond the solar system capable of supporting life have been delayed until the middle of next decade. While unmanned missions are facing a "tough time," the Enceladus discovery should spur interest in the hunt for alien life, said Bruce Runnegar, director of the NASA Astrobiology Institute. "This is the sort of thing that will help the astrobiology field get stronger and hopefully survive," Runnegar said. NASA does plan to land two more robotic probes on Mars this decade to search for ancient water and will launch the Kepler spacecraft to look for Earth-sized planets circling other stars. Astrobiologist Neville Woolf of the University of Arizona would like to see another mission answer whether Enceladus is life-friendly. "At some point, someone will have the courage and money to look at Enceladus," Woolf said. "As to when that will be, I'm no wiser than anyone else." |

We want the gigabucks to go to OUR program! Not YOUR program." Water Discovery May Not Spur Space Mission LOS ANGELES - To scientists scanning the cosmos for signs of life, the stunning discovery of what appears to be water on an obscure moon orbiting Saturn couldn't come at a more pivotal time. The science community is starting to whine about "no more flagship missions, fund a bunch of smaller missions instead" and an Enceladus mission is most certainly going to be in the flagship class, just like the cancelled Jupiter Icy Moons Orbiter and the now-off-the-radar Mars Sample Return Mission. And TPF just doesn't much excite me anyhow. "Woo hoo! We got a blurry itty bitty image of a mega-Jupiter orbiting Epsilon Eridanus..." Cool, I guess, but the fury over its cancellation seems way over the top to me. Brian |

You may wish to look at the distribution of funds being spent on science in this section of the budget. You also may wish to look at the amount of funds being spent on science in this section of the budget and compare that magnitude to other things such as the entire ESA budget. I find it interesting that articles such as that one mention Cassini but do not talk about the cost over runs there, the descoping of the mission, and a discussion about CR/AF. Then let's talk golf. -- rk, Just an OldEngineer "The number of people having any connection with the project must be restricted in an almost vicious manner.
