'''''Deep Impact''''' is a [[NASA]] [[space probe]] designed to study the composition of the interior of a [[comet]]'s nucleus. On [[July 4]], [[2005]], one section of the Deep Impact probe will smash into [[Comet Tempel 1]]'s nucleus and excavate a crater that will reveal the comet's interior.
 
Revision: 1.0 (Last updated on 14th November 2005) - Changelog
Previous space missions to comets, such as [[Giotto mission|Giotto]] and [[Stardust (spacecraft)|Stardust]], were merely fly-by missions, only able to photograph and examine the surfaces of cometary nuclei. The Deep Impact mission will be the first to examine a cometary interior, and thus, scientists hope, reveal new secrets about these small frozen bodies.

==Mission profile==
Following its launch on [[January 12]], [[2005]], the ''Deep Impact'' spacecraft is currently en-route to Comet Tempel 1. The journey will take 174 days at a cruising speed of 103,000 kilometers per hour (64,000 miles per hour). Once the spacecraft reaches the vicinity of the comet on [[July 3]], [[2005]], it will separate into two portions, an impactor and a flyby probe. The impactor will use its thrusters to move into the path of the comet, impacting 24 hours later at a relative speed of 37,000 kilometers per hour. The impactor has a mass of 370 [[kilogram]]s and will approach Tempel 1 with a relative speed of 10.2 kilometers per second (6.3 miles per second), thus delivering 1.9 &times; 10<sup>10</sup> [[joule]]s of [[kinetic energy]], the equivalent of 4.8 [[ton]]s of [[Trinitrotoluene|TNT]]. Scientists believe that the energy of this high-velocity collision will be sufficient to excavate a crater up to 100 meters wide (larger than the bowl of the Roman [[Colosseum]]), although the exact size is difficult to predict.
 
Just minutes after the impact, the flyby probe will pass by the nucleus at a close distance of 500 km, taking pictures of the crater, the ejecta plume, and the entire cometary nucleus. The entire event will also be photographed by Earth-based and orbital telescopes, such as the [[Hubble Space Telescope|Hubble]]. In addition, the impact will be observed by cameras and spectroscopes on board Europe's [[Rosetta space probe|Rosetta]] spacecraft, which will be about 80 million km from the comet at the time of impact. Rosetta should determine the composition of the gas and dust cloud kicked up by the impact. [http://www.esa.int/esaCP/SEMCOZ1DU8E_index_0.html]

==Scientific goals==
The Deep Impact mission will help answer fundamental questions about comets, such as:
*Is the composition of a cometary nucleus the same throughout, or has some physical process caused the interior to become differentiated from the surface? In other words, is the nucleus layered?
*Are cometary nuclei highly cohesive and tightly-packed, or porous conglomerates?
*Do any parts of a cometary nucleus contain pristine material that have been untouched since the creation of the comet during the [[Solar System]]'s early history?
Scientists hope that these questions will be answered, at least in part, by data from the Deep Impact mission. For example, the size and shape of the crater produced by the impact will tell scientists how well-packed the cometary material is.

==Spacecraft design and instrumentation==
[[Image:90855main_dispcrft.jpg|right||thumb|Spacecraft overview]]The spacecraft consists of two main sections, the 370 kg "Smart Impactor" which will impact the comet, and the "Flyby" section, which will image the crater created by the impactor.
 
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
The flyby section carries two cameras, the High Resolution Imager (HRI) and the Medium Resolution Imager (MRI). The HRI is an imaging device that combines a visible-light [[camera]], [[infrared]] [[spectrometer]], and an imaging module. It has been optimized for observing the comet's nucleus. The MRI is the backup device, and will primarily be used for navigation during the final 10-day approach.
 
== General Notes ==
The impactor section of the spacecraft contains an instrument that is nearly identical to the MRI. As the impactor nears the comet's surface, this camera will take high-resolution pictures of the nucleus (as good as 0.2 meters per pixel) to be transmitted in real-time to the flyby spacecraft before the impactor is destroyed.

==Mission events==
===Before launch===
A comet-impact mission was first proposed to NASA in [[1996]]. However, NASA engineers were skeptical that the target could be hit. [http://deepimpact.jpl.nasa.gov/mission/di-name.html] In [[1999]], a revised and technologically-upgraded mission proposal, dubbed Deep Impact, was accepted and funded as part of NASA's [[Discovery Program]] of low-cost space spacecraft. The name of the mission is shared with the ''[[Deep Impact (movie)| Deep Impact]]'' movie, in which a comet strikes the Earth, but this is coincidental, as both the scientists behind the mission and the creators of the movie devised the name independently of each other, at around the same time. [http://abcnews.go.com/US/wireStory?id=410785&CMP=OTC-RSSFeeds0312]
 
2. Guide is tested on a full installation of the Ubuntu 5.10 x86 Install CD (Breezy Badger).
===Launch and commissioning phase===
The probe was originally scheduled for launch on [[December 30]], [[2004]], but NASA officials delayed its launch, in order to allow more time for testing the [[software]]. It was successfully launched from [[Cape Canaveral]] on [[January 12]], [[2005]] at 1:47 p.m. EST (1847 UTC) by a [[Delta 2]] rocket.
 
3. If you see black box, means you have to execute the commands in Terminal mode (Applications -> System Tools -> Terminal).
''Deep Impact'''s state of health was uncertain during the first day after launch. Shortly after entering orbit around the Sun and deploying its solar panels, the probe switched itself to emergency backup mode. The exact cause and extent of the problem is not yet known, but NASA indicated that the on-board monitoring system detected an overheat problem. NASA subsequently announced that the probe was out of safe mode and healthy.
[http://www.nasa.gov/mission_pages/deepimpact/media/2005-016.html]
 
4. To reduce typo mistakes, copy and paste the commands into Terminal mode (right click on the commands -> "Copy" or "Paste").
On [[February 11]], ''Deep Impact'''s rockets were fired as planned to correct the spacecraft's course. This correction was so precise that the next planned maneuver for [[March 31]] was cancelled. During the "commissioning phase" all instruments were activated and checked out. During these tests it was found that the HRI images are not in focus after it underwent a bake-out period [http://www.spaceflightnow.com/news/n0503/25deepimpact/]. Mission members are investigating the problem. On [[June 9]], as part of a mission briefing, it was announced that by using image processing software and the mathematical technique of [[deconvolution#Optics| deconvolution]], the HRI images could be corrected to provide the resolution anticipated. [http://www.space.com/missionlaunches/050609_impact_camera.html]

===Cruise phase===
[[Image:PIA07879.jpg|right|thumb|[[Comet Tempel 1]] imaged on [[25 April]] by the Deep Impact spacecraft]]
The "cruise phase" began on [[March 25]], immediately after the commissioning phase was completed. This phase continued until about 60 days before the encounter with comet Tempel 1. On [[April 25]] the probe acquired the first image of its target at a distance of 64 million [[kilometre|km]] (39.7 million miles).
 
6. If you are tired of typing "sudo" all the time, switch to root user by issuing "sudo -s -H" followed by user password.
On [[May 4]] it executed its second trajectory correction maneuver. Burning its rocket engine for 95 seconds the spacecraft speed was changed by 18.2 kilometers per hour (11.3 miles per hour).
 
7. If you are tired of typing "apt-get" all the time, Read How to apt-get the easy way (Synaptic)?
===Approach phase===
The approach phase extends from 60 days before encounter until five days before
encounter. Sixty days out is about the earliest time that the Deep Impact spacecraft is expected to detect the comet with its MRI camera. In fact, the comet was spotted ahead of schedule, sixty-nine days before impact (see [[#Cruise phase|Cruise phase]] above). This milestone marks the beginning of an intensive period of observations to refine knowledge of the comet's orbit and study the comet's rotation, activity and dust environment. Impact is currently scheduled for 05:52 GMT on the morning of July 4.
 
8. "apt-get" and "wget" requires Internet connection to install/update/download programs.
On [[June 23]], the third trajectory correct maneuver was successfully executed. A 6 m/s (13.4 mph) velocity change was needed to adjust the flight path towards the comet.

==Contributions from amateur astronomers==
Since observing time on large, professional telescopes such as [[Keck telescopes|Keck]] or [[Hubble Space Telescope|Hubble]] is always scarce, the Deep Impact scientists have called on "advanced amateur, student, and professional astronomers" to use small telescopes to make long-term observations of the target comet before and after impact. The purpose of these observations is to look for "volatile outgassing, dust coma development and dust production rates, dust tail development, and jet activity and outbursts." Since 2000, amateur astronomers have submitted over a thousand [[CCD]] images of the comet. [http://deepimpact.umd.edu/stsp/]
 
10. Some multimedia applications may not load/produce sound, Read How to configure sound to work properly in GNOME?
The comet is currently too dim to be seen with anything smaller than a large backyard telescope, but it is possible that the impact on July 4th will brighten the comet substantially, making it visible through binoculars. [http://www.griffithobs.org/comettempel.html]
 
11. For any feedbacks, suggestions, discussions and bugs report to the author, please post comments: Here
==Controversy==
The mission has raised concerns among a small minority that believe that comets are made of [[antimatter]] and that the mission would cause a massive explosion, and among [[astrologers]], who believe that damaging a comet would disrupt their "system of spiritual values". One astrologer has even sued NASA over the mission. NASA has responded to the antimatter issue, which it does not find credible, but has not yet responded to the lawsuit, which was dismissed and then appealed in Russian courts.
 
12. May the "humanity to others" spirit be with you always...
The [[Planetary Society]], a space advocacy group, has responded to the astrologers by pointing out that the mission will merely "put a fresh hole on a comet with very many old holes from prior impacts." Overall, NASA spokeswoman Dolores Beasley says that the mission is "very popular".
