Mission News and Science

Deep Impact Update

Adapted from:
NASA Press Release: 05-177 – NASA'S Deep Impact Tells a Tale of the Comet
NASA Press Release: 05-251 – NASA'S Deep Impact Generates its own Spectacular Photo Flash
NASA Press Release: 05-250 – Deep Impact Kicks off 4th of July with Deep Space Fireworks

Deep Impact, a NASA Discovery Mission, was the first mission to probe beneath the surface of a comet and reveal the secrets of its interior. After spending 172 days and 268 million miles in pursuit of comet Temple 1, the Deep Impact spacecraft released its 820 pound impactor, which successfully collided with the comet. The collision between the coffee-table-sized impactor and city-sized comet occurred at 1:52 am EDT on July 4th. As the impactor struck the comet, the spacecraft collected data and relayed images and other information to eagerly waiting NASA scientists.

The impactor struck the comet at 6.3 miles per second, creating a bright flash of light, sending a plume of material into space, and leaving behind a crater. Scientists are analyzing data to determine the size of the crater, which may approach 250 meters across. They believe the impactor vaporized deep below the comet's surface during collision.

One surprise to scientists was the dense cloud of fine powdery material thrown up by the impact. This was not the icy debris that some people anticipated. The Deep Impact science team continues to look at data to determine more about the plume. The dust and light given off at impact suggest that the comet's surface is covered by extremely fine material – like talcum powder.

The Deep Impact mission will provide a glimpse beneath the surface of a comet, where material from our solar system's formation - four and a half billion years ago — remains relatively unchanged. Mission scientists hope to answer questions about the formation of the solar system by providing an in-depth picture of the nature and composition of comets.

Mars Reconnaissance Orbiter (MRO) - NASA's next mission to Mars!
NASA's scientists are excited about the next step in our exploration of the Red Planet — the Mars Reconnaissance Orbiter — due to launch beginning on August 10. The spacecraft will arrive at Mars in March 2006. It will occupy a low orbit above the Martian surface, providing immense detail about the features of this planet from the upper atmosphere to layers beneath the surface. Mission results will help scientists better understand how the Martian environment has changed through time, providing further insights into the history of water on Mars. The detailed data also will be used to identify possible future landing sites.

Possible Earth-like Planet Discovered
Modified from: Sky and Telescope
A planet that may be Earth-like — but too hot for life as we know it — has been discovered orbiting a nearby star. After three years of collecting evidence, a team of astronomers recently announced finding an entirely new type of planet orbiting a dim star 15 light-years away. The object is the lightest known extrasolar planet orbiting a normal star, with a mass between 6 and 9 Earths and an estimated radius about twice that of Earth .

The researchers have no direct proof that the new planet is rocky, but its mass suggests it is not a giant gas planet like Jupiter. The most probable composition of the planet is similar to inner planets of this solar system and it could even have a dense steamy water layer. Steamy is the right description — the estimated surface temperature on the planet is believed to be between 400 degrees and 750 degrees Fahrenheit!

Unprecedented Close Encounter with Mars? NOT This Year!!
Modified from: Approaching Mars
Space.com
Mars Watch 2003
Snopes.com
According to a forwarded email circulating for the past month or so, the planet Mars will have an unprecedented close encounter with Earth in August when its orbit brings it closer to Earth than it has been for thousands of years. Beware! This email is a recycled message from 2003 .

However, it's not entirely false. Earth and Mars will be close to one another again in the fall of 2005 ( October 30th at 0319 Greenwich Mean Time — a little after 10 pm Eastern Standard Time on the 29th) at which time their orbits will be a mere 43 million miles apart. While not the closest ever (35 million miles in August 2003), the approach is worth the look — Mars will outshine every object in the night sky except Venus and the Moon. 

Did You Know?
Modified from: Exploring Mars
Seasons change on Mars just as they do on Earth. Mars' orbit is more elliptical than Earth's so the distance between the Sun and Mars varies greatly over a Martian year — which is 687 days long. This large variation, combined with an axial tilt slightly greater than Earth's, causes greater seasonal changes than those on Earth.

When Mars is closest to the Sun in its orbit, its southern hemisphere is tilted toward the Sun, giving the southern hemisphere a short, very hot summer (the northern hemisphere is tilted away at this time, resulting in a short winter). When Mars is farthest from the Sun , the northern hemisphere is tilted toward the Sun; the northern region experiences a long, mild summer. At this time, the southern hemisphere is, of course, tilted away from the Sun, and so it experiences a long, cold winter. Seasonal changes can be seen in the surface features of Mars. The polar ice caps diminish in size as winter turns to spring in each of the hemispheres. For more information on seasons on Mars, check out Seasons and Climate on Mars.
