Preston Dyches, NASA Jet Propulsion Laboratory Twenty years ago, human and robotic eyes observed the first recorded impact between cosmic bodies in the solar system, as fragments of comet Shoemaker-Levy 9 slammed into the atmosphere of Jupiter. Between July 16 and July 22, 1994, space- and Earth-based assets managed by NASA's Jet Propulsion Laboratory in Pasadena, California, joined an armada of other NASA and international telescopes, straining to get a glimpse of the historic event: -...

Engaged couple to recite vows before the gun fires at 35th Annual Lilac Bloomsday Run May 1, 2011 in Spokane, Wash. Spokane, WA (PRWEB) March 24, 2011 Spokane's Lilac Bloomsday Run, held every year on the first Sunday of May, is the world's largest timed 12k race with upwards of 60,000 participants each year. But what makes this 35th Anniversary run especially unique is it will likely be the largest wedding ceremony of the decade. When planning their upcoming nuptials, Bloomsday veterans...

British scientists have identified a new candidate for the biggest comet measured to date. Dr Geraint Jones of UCL's Mullard Space Science Laboratory will be presenting the results at the RAS National Astronomy Meeting in Glasgow on Tuesday April 13th. Instead of using the length of the tail to measure the scale of the comet, the group has used data from the ESA/NASA Ulysses spacecraft to gauge the size of the region of space disturbed by the comet's presence. Analysis of magnetometer data...

The Ulysses spacecraft, a joint NASA-European Space Agency mission, has officially ceased operations, officials said. The end-of-mission command was transmitted Tuesday to the spacecraft that operated for more than 18 years, charting the unexplored regions of space above the poles of the sun. When space shuttle Discovery launched Ulysses on Oct. 6, 1990, it had an expected lifetime of five years, NASA said. This has been a remarkable scientific endeavor, said Richard Marsden, Ulysses mission...

Scientists said goodbye to the Ulysses solar probe on Tuesday, following 18 years of activity. "Ulysses has taught us more than we ever expected about the sun and the way it interacts with the space surrounding it," said Richard Marsden, Ulysses project manager with the European Space Agency (ESA). Named for the Latin translation of Odysseus, after Dante's Inferno, the veteran solar probe has been retrieving data for more than 18 and 1/2 years - four times longer than scientists had...

Upon receipt of the last command from Earth, the transmitter on Ulysses will switch off on 30 June, bringing one of the most successful and longest missions in spaceflight history to an end. After 18.6 years in space and defying several earlier expectations of its demise, the joint ESA/NASA solar orbiter Ulysses will achieve 'end of mission' on 30 June 2009. The final communication pass with a ground station will start at 17:35 CEST and run until 22:20 CEST (15:35-20:20 UTC) or until the...

Data from the Ulysses spacecraft, a joint NASA-European Space Agency mission, show the sun has reduced its output of solar wind to the lowest levels since accurate readings became available. The sun's current state could reduce the natural shielding that envelops our solar system. "The sun's million mile-per-hour solar wind inflates a protective bubble, or heliosphere, around the solar system. It influences how things work here on Earth and even out at the boundary of our solar system where...

The Ulysses spacecraft, whose mission was expected to end on July 1, 2008, is hanging on valiantly as spacecraft controllers wait for a sign of the fuel freeze that would end the mission. This could happen any time now. Controllers will know that the fuel needed to keep the antenna pointing towards Earth has started to freeze when Earth-pointing manoeuvres become less efficient and the radio signals from the spacecraft grow weaker.  In the meantime, Ulysses is still providing...

After more than 17 years of pioneering solar science, a joint NASA and European Space Agency mission to study the sun will end on or about July 1.The Ulysses spacecraft has endured for almost four times its expected lifespan. However, the spacecraft will cease operations because of a decline in power produced by its onboard generators. Ulysses forever has changed the way scientists view the sun and its effect on the surrounding space. Mission results and the science legacy it leaves behind...

Standard microscopy and visible light imaging techniques cannot peer into the dark and murky centers of dense-liquid jets, which has hindered scientists in their quest for a full understanding of liquid breakup in devices such as automobile fuel injectors. Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory have developed a technique to peer through high-speed dense liquids using high-energy X-rays from Argonne's Advanced Photon Source (APS). "The imaging contrast...

Discovery launched from Kennedy Space Center on October 6, 1990 at 6:57 AM PDT and landed at Edwards Air Force Base on October 10 at 6:57 AM PDT. The shuttle orbited 66 times at an inclination of 28.45 degrees at an altitude of 160 nautical miles and travelled 1.7 million miles. The mission lasted 4 days, 2 hours, 10 minutes, and 4 seconds. This mission launched the Ulysses probe to study the polar regions of the Sun. Two upper stages of Ulysses, the Inertial Upper Stage (IUS) and a...
