The Secrets Minerva And Its Two Moons
2011-10-06 08:30:47

Since the discovery of its two moons, the triple asteroid Minerva has been the focus of space and ground-based telescope studies that have attempted to unravel the secrets of this intriguing system. A multiple-telescope campaign has now revealed that Minerva is unusually round for an asteroid, and has a possibly unique structure.  The campaign to “weigh” the asteroid and derive its density and other characteristics was undertaken by an international team of planetary...

Data collected during MESSENGER´s first two months in orbit around Mercury have been released to the public by the Planetary Data System (PDS), an organization that archives and distributes all of NASA´s planetary mission data. Calibrated data from all seven of MESSENGER´s science instruments, plus radio science data from the spacecraft telecommunications system, are included in this release. “It's a real milestone for the first data ever obtained from orbit around...

Water ice on asteroids may be more common than expected, according to a new study that was presented October 7 at the world's largest gathering of planetary scientists. Two teams of researchers who made national headlines in April for showing the first evidence of water ice and organic molecules on an asteroid have now discovered that asteroid 65 Cybele contains the same material. "This discovery suggests that this region of our solar system contains more water ice than anticipated," said...

A huge asteroid visited by Europe's Rosetta probe is encased in a thick, dusty layer of debris at least 2,000 ft. deep, created by eons of impacts that have left the shattered surface with a texture similar to the Earth's Moon. The findings are among the first to emerge from the plethora of data collected by Rosetta during its close flyby of Lutetia 282 million miles from Earth, beyond the orbit of Mars. Details of the encounter are being presented at a conference this week of the Division...

Asteroid Lutetia has been revealed as a battered world of many craters. ESA's Rosetta mission has returned the first close-up images of the asteroid showing it is most probably a primitive survivor from the violent birth of the Solar System. The flyby has been a spectacular success with Rosetta performing faultlessly. Closest approach took place at 18:10 CEST, at a distance of 3162 km. The images show that Lutetia is heavily cratered, having suffered many impacts during its 4.5 billion years...

On its way to a 2014 rendezvous with comet 67P/Churyumov-Gerasimenko, the European Space Agency's Rosetta spacecraft, with NASA instruments aboard, will fly past asteroid Lutetia today (July 10). The instruments aboard Rosetta will record the first close-up image of a metal asteroid. They will also make measurements to help scientists derive the mass of the object, understand the properties of the asteroid's surface crust, record the solar wind in the vicinity and look for evidence of an...

The media are invited to ESA's Space Operations Centre in Darmstadt, Germany to follow Rosetta's encounter with asteroid Lutetia on July 10, 18:00"“23:00. The first images of the asteroid will be released before midnight, with experts available for interview. ESA's Rosetta comet-chaser is en route to its main target, comet 67P/ Churyumov-Gerasimenko, arriving in 2014. On Saturday, July 10 it will fly past the previously unvisited asteroid Lutetia. This is an important milestone in...

The Rosetta Orbiter, a European Space Agency spacecraft heading for a 2014 encounter with a comet, will be flying close to asteroid Lutetia on Saturday, July 10. Classes and clubs are invited to NASA's Jet Propulsion Laboratory from 2 to 4 p.m. that day to see first-ever, close-up images of Lutetia, talk to a NASA/JPL Rosetta project manager and participate in educational activities. Lutetia is a large metal-rich asteroid and part of the main asteroid belt between Mars and Jupiter. Rosetta...

ESA's comet-chaser Rosetta is heading for a blind date with asteroid Lutetia. Rosetta does not yet know what Lutetia looks like but beautiful or otherwise the two will meet on July 10th. Like many first dates, Rosetta will meet Lutetia on a Saturday night, flying to within 3200 km of the space rock. Rosetta started taking navigational sightings of Lutetia at the end of May so that ground controllers can determine any course corrections required to achieve their intended flyby distance. The...

Close-up images of asteroid (2867) Steins, obtained with the OSIRIS cameras on Rosetta, have provided extensive new measurements of the physical properties of this main-belt asteroid. Steins is revealed to be a loosely-bound 'rubble pile' whose diamond shape has been honed by the YORP effect. This is the first time this effect has been seen in a main-belt asteroid. The results are reported by H. Uwe Keller and colleagues in the January 8 issue of Science magazine. Most models of Solar System...

Ernst Wilhelm Leberecht Tempel was born on December 4, 1821 in Germany and died March 16, 1889. Tempel worked in Marseille until the onset of the Franco Prussian War in 1870 at which time he relocated to Italy. Tempel discovered or assisted in discovering 21 comets. The Tempel asteroid 3808 and lunar crater Tempel are named in his honor. His most notable discoveries include the following asteroids 564 Angelina, 65 Cybele, 74 Galatea, 81 Terpsichore and 97 Klotho.

Maximilian Franz Joseph Cornelius Wolf (June 21, 1863 - October 3, 1932) was a German astronomer and pioneer of astrophotography. He is accredited with the discovery of a large quantity of asteroids. Heidelberg, Germany was his birthplace. He received his PhD at the University of Heidelberg in 1888, and in 1890 he took employment in that institution. Beginning in 1891, Wolf discovered more than 200 asteroids with the Bruce double-astrograph, while working at the Landessternwarte...

La Silla Observatory -- La Silla is a 2400-m mountain, bordering the southern extremity of the Atacama desert in Chile. It is located about 160 Km north of La Serena. Its geographical coordinates are: Latitude 29 15' south & Longitude 70 44' west. Originally known as Cinchado, the mountain was renamed La Silla (the saddle) after its shape. It rises quite isolated and remote from any artificial light and dust sources (astronomy's worst enemies). La Silla was the first ESO...
