<I know alot of us post when we see nasa/space stuff if its a bulltin is it possible we can sign up to this service here and be E-mailed availablity of news bulletings available at or maybe a extra button on the left saying whats happening today.

I think that the magic is having all those eyes extracting information from all the different sources out there. The 'up-to-the-minute' information that everyone here gathers and posts here has been well thought out and has been very valuable. I know that there are message board programs that will e-mail the original poster if there was a response, but I don't know how or if Robert is able to do that here.

just that from time to time i miss live feeds from nasa.com as i,m in uk and the only available nasa feed is from there site :(

NASA has an email service for their latest news that you can sign up for (see sample below). You can also get e-mail service for certain missions (Cassini, etc.). Of course, your email box could be stuffed in no time if you don't check it often.

launch flashes etc.. would be nice

That would be nice. It may be possible for Robert to 'make an icon flash' ;) lol.
It may be a while before the next actual launch. Hopefully, very soon.

NASA SOLVES HALF-CENTURY OLD MOON MYSTERY

In the early morning hours of Nov. 15, 1953, an amateur astronomer in Oklahoma photographed what he believed to be a massive, white-hot fireball of vaporized rock rising from the center of the moon's face. If his theory was right, Dr. Leon Stuart would be the first and only human in history to witness and document the impact of an asteroid sized body impacting the moon's scarred exterior.

Almost a half-century, numerous space probes and six manned lunar landings later, what had become known in astronomy circles, as "Stuart's Event" was still an unproven, controversial theory. Skeptics dismissed Stuart's data as inconclusive and claimed the flash was a result of a meteorite entering Earth's atmosphere. That is, until Dr. Bonnie J. Buratti, a scientist at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, and Lane Johnson of Pomona College, Claremont, Calif., took a fresh look at the 50-year-old lunar mystery.

"Stuart's remarkable photograph of the collision gave us an excellent starting point in our search," said Buratti. "We were able to estimate the energy produced by the collision. But we calculated that any crater resulting from the collision would have been too small to be seen by even the best Earth-based telescopes, so we looked elsewhere for proof."

Buratti and Lane's reconnaissance of the 35-kilometer (21.75-mile) wide region where the impact likely occurred led them to observations made by spacecraft orbiting the moon. First, they dusted off photographs taken from the Lunar Orbiter spacecraft back in 1967, but none of the craters appeared a likely candidate. Then they consulted the more detailed imagery taken from the Clementine spacecraft in 1994.

"Using Stuart's photograph of the lunar flash, we estimated the object that hit the moon was approximately 20 meters
(65.6 feet) across, and the resulting crater would be in the range of one to two kilometers (.62 to 1.24 miles) across. We were looking for fresh craters with a non-eroded appearance," Buratti said.

Part of what makes a moon crater look "fresh" is the appearance of a bluish tinge to the surface. This bluish tinge indicates lunar soil that is relatively untouched by a process called "space weathering," which reddens the soil. Another indicator of a fresh crater is that it reflects distinctly more light than the surrounding area.

Buratti and Lane's search of images from the Clementine mission revealed a 1.5 kilometer (0.93 mile) wide crater. It had a bright blue, fresh-appearing layer of material surrounding the impact site, and it was located in the middle of Stuart's photograph of the 1953 flash. The crater's size is consistent with the energy produced by the observed flash;
it has the right color and reflectance, and it is the right shape.

Having the vital statistics of Stuart's crater, Buratti and Lane calculated the energy released at impact was about .5
megatons (35 times more powerful than the Hiroshima atomic bomb). They estimate such events occur on the lunar surface once every half-century.

"To me this is the celestial equivalent of observing a once-in-a-century hurricane," observed Buratti. "We're taught the moon is geologically dead, but this proves that it is not. Here we can actually see weather on the moon," she said.

While Dr. Stuart passed on in 1968, his son Jerry Stuart offered some thoughts about Buratti and Lane's findings. "Astronomy is all about investigation and discovery. It was my father's passion, and I know he would be quite pleased," he said.

Buratti and Lane's study appears in the latest issue of the space journal, Icarus.

The NASA Planetary Geology and Planetary Astronomy Programs and the National Science Foundation funded Buratti's work. The California Institute of Technology manages JPL for NASA.
