date	01.12.2005
description	Erupting from the flames and smoke beneath it, NASA's Deep Impact spacecraft lifts off at 1:47 p.m. EST today from Launch Pad 17-B, Cape Canaveral Air Force Station, Fla. A NASA Discovery mission, Deep Impact is heading for space and a rendezvous 83 million miles from Earth with Comet Tempel 1. After releasing a 3- by 3-foot projectile (impactor) to crash onto the surface July 4, 2005, Deep Impact's flyby spacecraft will reveal the secrets of the comet's interior by collecting pictures and data of how the crater forms, measuring the crater's depth and diameter as well as the composition of the interior of the crater and any material thrown out, and determining the changes in natural outgassing produced by the impact. It will send the data back to Earth through the antennas of the Deep Space Network. Image Credit: NASA

Date of Image	2005-07-04
Full Description	After 172 days and 268 million miles of deep space travel, the NASA Deep Impact spacecraft successfully reached out and touched comet Tempel 1. The collision between the coffee table-sized space probe and city-sized comet occurred July 4, 2005 at 12:52 a.m. CDT. Comprised of images taken by the targeting sensor aboard the impactor probe, this movie shows the spacecraft approaching the comet up to just seconds before impact. Mission scientists expect Deep Impact to provide answers to basic questions about the formation of the solar system. Principal investigator for Deep Impact, Dr. Michael A?Hearn of the University of Maryland in College Park, is responsible for the mission, and project management is handled by the Jet Propulsion Laboratory in Pasadena, California. The program office at the Marshall Space Flight Center (MSFC) in Huntsville, Alabama assisted the Science Mission Directorate at NASA Headquarters in Washington with program management, technology planning, systems assessment, flight assurance and public outreach. The spacecraft was built for NASA by Ball Aerospace & Technologies Corporation of Boulder, Colorado. (NASA/JPL-Caltech/UMD)

Deep Impact Spacecraft Hurtles Toward Comet

Title	Deep Impact Spacecraft Hurtles Toward Comet
Explanation	What happens when you crash into a comet? That was a question considered by astronomers [ http://deepimpact.jpl.nasa.gov/mission/bios.html ] when they designed the Deep Impact mission [ http://deepimpact.jpl.nasa.gov/index.html ], launched in January. This coming July 4, the Deep Impact spaceship will reach its target - Comet Tempel 1 [ http://antwrp.gsfc.nasa.gov/apod/ap050512.html ] -- and release an impactor over five times the mass of a person toward its surface. The mothership will photograph the result. The remaining crater [ http://www.planetary.org/deepimpact/di_crater.html ] may tell how Tempel 1 is constructed. If, for example, Comet Tempel 1 [ http://deepimpact.jpl.nasa.gov/science/tempel1.html ] is an extremely loose pile of debris, the impactor may leave little or no discernable crater. On the other hand, if the comet's surface is relatively firm, the impactor's ripple may leave quite a large crater. A contest is even being held [ http://www.planetary.org/deepimpact/contest_enter.html ] to predict the size of the resulting crater. Pictured above [ http://www.planetary.org/deepimpact/di.html ] is an artist's impression of the initial encounter between the spacecraft and the comet.

Thirteen Million Kilometers from Comet Tempel 1

Thirteen Million Kilometers …

Title	Thirteen Million Kilometers from Comet Tempel 1
Explanation	The Deep Impact spacecraft continues to close on Comet Tempel 1, a comet roughly the size of Manhattan. Early on July 3 (EDT), the Deep Impact [ http://deepimpact.jpl.nasa.gov/home/index.html ] spacecraft will separate [ http://www.space.com/businesstechnology/technology/050615_deepimpact_tech.html ] in to two individual robotic spaceships, one called Flyby and the other called Impactor. During the next 24 hours, both Flyby and Impactor will fire rockets and undergo complex maneuvers in preparation for Impactor's planned collision [ http://antwrp.gsfc.nasa.gov/apod/ap050516.html ] with Comet Tempel 1 [ http://deepimpact.jpl.nasa.gov/science/tempel1.html ]. On July 4 (1:52 am EDT) if everything goes as scheduled, the 370-kilogram Impactor will strike Tempel 1 [ http://cometography.com/pcomets/009p.html ]'s surface at over 14,000 kilometers per hour. Impactor will attempt to photograph the oncoming comet right up to the time of collision, while Flyby photographs the result from nearby. The above image [ http://deepimpact.jpl.nasa.gov/gallery/DI_T1_doy171.html ] was taken on 19 June from about 13 million kilometers out and used to help identify the central nucleus [ http://deepimpact.jpl.nasa.gov/press/050621umd.html ] of the comet inside the diffuse coma [ http://www.windows.ucar.edu/tour/link=/comets/coma.html ]. Telescopes around the Earth, including the Hubble Space Telescope, will also be closely watching [ http://hubblesite.org/newscenter/newsdesk/ archive/releases/2005/16/ ] the distant silent space ballet [ http://www.ebertfest.com/three/32001.htm ]. The result may give crucial information about the structure of comets [ http://antwrp.gsfc.nasa.gov/apod/ap040319.html ] and the early history of our Solar System [ http://www.bbc.co.uk/science/space/origins/building/index.shtml ].

The Landscape on Comet Tempe …

Title	The Landscape on Comet Tempel 1
Explanation	This diverse landscape is the surface of comet Temple 1's [ http://antwrp.gsfc.nasa.gov/apod/ap050512.html ] nucleus as seen by the Deep Impact probe's Impactor Targeting Sensor [ http://deepimpact.jpl.nasa.gov/tech/impactor.html ]. Within minutes of recording the rugged view [ http://photojournal.jpl.nasa.gov/catalog/PIA02135 ], the landscape had changed dramatically though, as the impactor smashed into the surface near the two large, half kilometer-sized craters at picture center. Indications [ http://photojournal.jpl.nasa.gov/catalog/ PIA02131 ] are that the probe penetrated well below the surface before vaporizing, sending a relatively narrow plume of debris blasting back into space. Researchers are still speculating on the final size of the crater [ http://www.deepimpact.umd.edu/science/ cratering.html ] produced by the July 4th comet crash [ http://www.deepimpact.umd.edu/press/ 050704a-jpl.html ], but material continues to spew from the impact site and has caused the faint comet [ http://deepimpact.umd.edu/collab_pub/imagep.shtml ] to brighten significantly. Determining the crater dimensions and analyzing the debris ejected from the comet's interior will provide premier insights into the formation of comet Tempel 1 [ http://www.deepimpact.umd.edu/science/tempel1.html ], a primordial chunk of our own solar system.

A Swift Look at Tempel 1

Title	A Swift Look at Tempel 1
Explanation	Comet Tempel 1 is targeted for a collision [ http://antwrp.gsfc.nasa.gov/apod/ap050516.html ] with the impactor probe from NASA's Deep Impact Spacecraft at about 1:52am EDT on July 4th (other time zones [ http://deepimpact.jpl.nasa.gov/faq5.html#q1 ]). Cameras on the impactor probe and the flyby spacecraft will capture close-up images of the event - expected to produce [ http://deepimpact.jpl.nasa.gov/mission/wwws.html ] a crater on the surface of the comet's nucleus. Of course, Earth-orbiting [ http://hubblesite.org/newscenter/newsdesk/archive/ releases/2005/16/ ] and ground-based telescopes will be watching too, including instruments on the Swift satellite normally used to spot gamma-ray bursts [ http://swift.gsfc.nasa.gov/docs/swift/swiftsc.html ] in the distant universe. Swift's ultraviolet telescope recorded this picture of Tempel 1 [ http://swift.gsfc.nasa.gov/docs/swift/results/releases/ images/9P_Tempel1/ ] on June 29th. Because the image is registered on the comet, the background stars appear as short trails. Want to follow the encounter? Media coverage chronicling the event, and the possibilities for viewing the comet [ http://deepimpact.umd.edu/amateur/ ] with small telescopes can be found through the Deep Impact website [ http://deepimpact.jpl.nasa.gov/home/index.html ]. Updated images will also be available from the Kitt Peak National Observatory [ http://www.noao.edu/news/deep-impact/ ].

Title	The Road to Tempel (Artist's Concept)
Original Caption Released with Image	"" Quick Time Movie for PIA02106 The Road to Tempel This animation chronicles the travels of NASA's Deep Impact spacecraft, from its launch in January of 2005 to its dramatic impact 172 days later with comet Tempel 1. The times listed below were updated on July 2, 2005, and differ from those referred to in the animation. The final phase of the mission, called the encounter phase, includes two targeting maneuvers, the last of which occurs at 5:07 p.m. Pacific time (8:07 p.m. Eastern time), July 2. Six hours later, the spacecraft releases an impactor into the path of the charging comet. Twelve minutes later, the remaining craft, called the flyby, steers itself away from the comet's path. The free impactor then autonomously fine-tunes its trajectory, with the goal of hitting the sunlit side of Tempel 1. Impact is scheduled to occur at 10:52 p.m. Pacific time, July 3 (1:52 a.m. Eastern time, July 4). The flyby spacecraft will watch the collision from the sidelines, snapping pictures up to 13 minutes after impact. At that point, the craft stops taking images and enters a protective mode, in which its shields block dust from the comet's inner coma. Fifty-nine minutes after impact, the flyby turns around for one last photo opportunity.

It Happens in a Flash

PIA02108

Title	It Happens in a Flash
Original Caption Released with Image	This image shows a flash produced in a laboratory by a high-velocity bead slamming into dust. Though the flash itself can't be resolved, its brilliant effects can be seen in this three-second time exposure. Scientists say that the collision between Deep Impact's impactor and comet Tempel 1 may produce a similar flash. This flash occurred when a quarter-inch sphere smashed into powdered dust at a speed of 6.4 kilometers per second (4 miles per second). Even though the actual flash lasted less than 50 millionths of a second, the camera recorded the hot debris in the impact crater (center) and the streaking ejecta. This experiment was performed at NASA's Ames Research Center, Moffett Field, Calif.

Original Caption Released with Image	Figure 1: X-ray Eyes on Tempel This false-color image shows comet Tempel 1 as seen by Chandra X-ray Observatory on June 30, 2005, Universal Time. The comet was bright and condensed. The X-rays observed from comets are caused by an interaction between highly charged oxygen in the solar wind and neutral gases from the comet. The observatory detected X-rays with an energy of 0.3 to 1.0 kilo electron Volts. The bulk of the X-rays were between 0.5 and 0.7 kilo electron Volts. Chandra will observe the comet for 18 hours during and after the time when NASA's Deep Impact impactor probe collides with Tempel 1 at 10:52 p.m. Pacific time, July 3 (1:52 a.m. Eastern time, July 4). The material ejected from the crater could cause the interaction region, and thus the X-ray emission, to move toward the Sun.

Moment of Impact

PIA02131

Sol (our sun)

Impactor Targeting Sensor

Title	Moment of Impact
Original Caption Released with Image	When NASA's Deep Impact probe collided with Tempel 1, a bright, small flash was created, which rapidly expanded above the surface of the comet. This flash lasted for more than a second. Its overall brightness is close to that predicted by several models. After the initial flash, there was a pause before a bright plume quickly extended above the comet surface. The debris from the impact eventually cast a long shadow across the surface, indicating a narrow plume of ejected material, rather than a wide cone. The Deep Impact probe appears to have struck deep, before gases were heated and explosively released. The impact crater was observed to grow in size over time. A preliminary interpretation of these data indicate that the upper surface of the comet may be fluffy, or highly porous. The observed sequence of impact events is similar to laboratory experiments using highly porous targets, especially those that are rich in volatile substances. The duration of the hot, luminous gas phase, as well as the continued growth of the crater over time, all point to a model consistent with a large crater. This image was taken by Deep Impact's medium-resolution camera.

Original Caption Released with Image	This image of the surface of comet Tempel 1 was taken about 20 seconds before Deep Impact's probe crashed into the comet at 10:52 p.m. Pacific time, July 3. This particular region contains the impact site. The bright patches in the image may consist of very smooth and reflective material, the composition of which will be determined by Deep Impact's spectrometer. Dark areas are in shadow and provide information about surface topography. Higher terrain appears rough relative to lower areas that appear very smooth. Is this a layered surface? And how did the smooth regions form? These are some of the questions the science team plans to address. This image was taken by the probe's impactor targeting sensor.

Original Caption Released with Image	This image shows how Deep Impact's impactor targeted comet Tempel 1 as the spacecraft made its final approach in the early morning hours of July 4, Eastern time. The autonomous navigation system on the probe was designed to make as many as three impactor targeting maneuvers, identified as ITMs in this picture, to correct its course to the comet. The upper left dot indicates where the probe would have passed the comet's nucleus if no maneuvers were performed. The dot below the nucleus shows where the probe would have flown past the comet if only the first maneuver was made. The leftmost dot on the nucleus marks the spot where the probe would have crunched the comet if only the first two maneuvers had been performed. The lower dot on the nucleus indicates the vicinity where, once the third maneuver was performed, the probe met its final reward and collided with the comet.

Title	Tempel Alive with Light
Original Caption Released with Image	This spectacular image of comet Tempel 1 was taken 67 seconds after it obliterated Deep Impact's impactor spacecraft. The image was taken by the high-resolution camera on the mission's flyby craft. Scattered light from the collision saturated the camera's detector, creating the bright splash seen here. Linear spokes of light radiate away from the impact site, while reflected sunlight illuminates most of the comet surface. The image reveals topographic features, including ridges, scalloped edges and possibly impact craters formed long ago.

When this 820-pound ?impactor? hits the surface of the comet at nearly 23,000 miles per hour, the 3- by 3-foot projectile will create a crater hundreds of feet in size. Deep Impact?s flyby spacecraft will collect pictures and data of how the crater forms, measuring the crater?s depth and diameter, as well as the composition of the interior of the crater and any material thrown out, and determining the changes in natural outgassing produced by the impact. It will send the data back to Earth through the antennas of the Deep Space Network. The spacecraft is scheduled to launch Dec. 30, 2004, aboard a Boeing Delta II rocket from Launch Complex 17 at Cape Canaveral Air Force Station, Fla.
