Mission News and Science

NASA'S Orbiter Nears Red Planet Rendezvous
NASA's Mars Reconnaissance Orbiter (MRO) spacecraft launched August 12, 2005.  Its purposes included to advance human understanding of Mars through detailed observation, to examine potential landing sites for future surface missions, and to provide a high-data-rate communications relay for those missions. It is intended to orbit for four years, and to become Mars' fourth active artificial satellite (joining Mars Express, Mars Odyssey, and Mars Global Surveyor), and its sixth active probe (the satellites plus the two Mars Exploration Rovers), in a historic scientific focus on the Red Planet.

Currently, NASA's MRO is preparing to slow itself to allow the red planet's gravity to grab it into orbit on March 10. Designed to examine the planet in unprecedented detail, the orbiter will return more data than all previous Mars missions combined. Before the orbiter can begin its mission, it will spend approximately six months adjusting its orbit with an adventurous process called aerobraking.

The initial capture by Martian gravity will put the orbiter into an elongated, 35-hour orbit. The planned orbit for science observations is a low-altitude, nearly circular, two-hour loop. Aerobraking will use hundreds of carefully calculated dips into the upper atmosphere, deep enough to slow the spacecraft by atmospheric drag, but not deep enough to overheat the orbiter, to gain the desired orbit.

The orbiter carries six instruments that will produce data for studying Mars from underground layers to the top of the atmosphere. They include the most powerful telescopic camera ever sent to another planet; it will reveal rocks the size of a small desk. An advanced mineral-mapper will be able to identify water-related deposits in areas as small as a baseball infield. Radar will probe for buried ice and water. A weather camera will monitor the entire planet daily. An infrared sounder will monitor atmospheric temperatures and the movement of water vapor. Visit the MRO Web site for more information.
The Tenth Planet
Modified from: http://www.universetoday.com/am/publish/10th_planet_pluto.html?122006
Is there a tenth planet in our solar system? Claims that the solar system has a tenth planet are bolstered by the discovery that this alleged planet, announced last summer and tentatively named 2003 UB313, is bigger than Pluto.

Like Pluto, 2003 UB313 is one of the icy bodies in the Kuiper belt that exists beyond Neptune. It is the most distant object ever seen in the solar system. Its very elongated orbit takes it up to 97 times farther from the Sun than is the Earth — almost twice as far as the most distant point of Pluto's orbit — so that it takes twice as long as Pluto to orbit the Sun. When it was first seen, UB313 appeared to be at least as big as Pluto. But recent evidence suggests that it is decidedly larger. Since UB313 is larger than Pluto why call Pluto a planet? Should scientists call UB313 a planet?

Astronomers have found small planetary objects in the Kuiper belt beyond the orbits of Neptune and Pluto since 1992. UB313 is a member of a ring of some 100,000 objects in the “belt” on the outskirts of the solar system. The Kuiper belt contains objects left from the formation of our planetary system some 4.5 billion years ago. In their distant orbits they were able to survive the gravitational clean-up of similar objects by the large planets in the inner solar system. Some Kuiper Belt objects are still occasionally deflected, then enter the inner solar system and may appear as short period comets.

Mars Fossil Search?
Modified from: http://www.universetoday.com/am/publish/3d_fossil_imaging.html?122006
UCLA paleobiologist J. William Schopf and colleagues have produced 3-D images of ancient fossils — 650 million to 850 million years old - preserved in rocks, an achievement that has never been done before. If a future space mission to Mars brings rocks back to Earth, Schopf said the techniques he has used, called confocal laser scanning microscopy and Raman spectroscopy, could enable scientists to look at microscopic fossils inside the rocks to search for signs of life, such as organic cell walls. These techniques would not destroy the rocks.

These processes allow scientists to look underneath the fossil, see it from the top, from the sides, and rotate it around. In addition, even though the fossils are exceedingly tiny, the images are sharp and crisp.

Schopf is the director of UCLA's Institute of Geophysics and Planetary Physics Center for the Study of Evolution and the Origin of Life. Since his first year as a Harvard graduate student in the 1960s, Schopf had the goal of conducting chemical analysis of an individual microscopic fossil inside a rock, but had no technique to do so, until now.

Deep Impact Update
NASA’s Deep Impact mission was the first to probe beneath the surface of a comet and reveal the secrets of its interior. After spending 172 days in pursuit of comet Temple 1, the Deep Impact spacecraft’s impactor successfully collided with the comet on July 4th, 2005. The spacecraft collected data and relayed images and other information to NASA scientists.

The latest finding reveals that Comet Tempel 1 is covered with a small amount of water ice. These results offer the first definitive evidence of surface ice on any comet. The water ice on the surface of Tempel 1 could offer important insight into understanding a comet’s water cycle and supply which is critical to understanding these bodies as a system and as a possible source that delivered water to Earth. Water and the large organic component in comets equates into two of the key ingredients for life.

The findings help fulfill one of the major goals of the Deep Impact mission: Find out what is on the inside — and outside — of a comet. The Deep Impact team has reported a few other key findings. These include an abundance of organic matter in Tempel 1’s interior as well as its likely origins — the region of the solar system now occupied by Uranus and Neptune. The team arrived at their findings by analyzing data captured by an infrared spectrometer, an optical instrument that uses light to determine the composition of matter. Based on this spectral data, it appears that the surface ice used to be inside Tempel 1 but became exposed over time. The team reports that jets — occasional blasts of dust and vapor — may send this surface ice, as well as interior ice, to the coma, or tail, of Tempel 1. This shows that Tempel 1 is a geologically active body whose surface is changing over time.

Saturn’s Violent Nature
Did you know that Saturn's atmosphere is filled with violent electrical storms and high speed winds? In fact, Saturn is one of the windiest places in the solar system with wind speeds at over 1000 miles per hour at the equator. Occasionally, violent storms break through the cloud layers, each one bigger than Earth. Smaller storms occur as darker spots, and have been shown in recent Cassini-Huygens spacecraft images.

Currently there is an electrical storm larger than the United States — in which the lightning bolts are more than 1,000 times stronger than conventional lightning — brewing on Saturn! This storm is the strongest of its kind ever seen and University of Iowa space scientists have been utilizing data from Cassini to track the storm since January 23.

With Cassini the space scientists have learned that lightning storms on Saturn can emerge suddenly and last for several weeks or even a month. This current storm has varied in intensity, but has continued with some 25 episodes since first noticed on January 23. The origin of such storms is unknown, but may be related to Saturn's warm interior.

The radio sounds of Saturn's lightning can be heard by visiting the Space Audio Web site. Check this site for information on Cassini Radio and Plasma Wave Science. A Podcast of this story and other Cassini mission information is available at the Cassini-Huygens Web site and at Unlocking Saturn's Secrets.
