. The Hayabusa mission profile has been modified several times, both before and after launch. Gibson is also the surname of several notable people:. Second, since it was the first-ever soft contact with the surface of an asteroid it has enormous influence on further asteroid missions. In Australia:. First it will help JAXA to further test its technologies in the fields of ion engines, autonomous and optical navigation, deep space communication, and close movement on objects with low gravity among others. In the United States:. The Hayabusa mission has a very deep engineering importance for JAXA, too.

Gibson may refer to:. 1 Also in comparing the data from the onboard instruments of the Hayabusa with the data from the Near Shoemaker mission will put the knowledge on a wider level. . Accordingly, Hayabusa "will bridge the gap between ground observation data of asteroids and laboratory analysis of meteorite and cosmic dust collections," says mission scientist Hajime Yano. William Gibson (Catholic martyr). Hayabusa will solve this problem by bringing back pristine samples from a specific, well-characterized asteroid. William Gibson (novelist), the science fiction, cyberpunk novelist, author of Neuromancer. Scientists' current understanding of asteroids depends greatly on meteorite samples, but it is very difficult to match up meteorite samples with the exact asteroids from which they came.

William Gibson (playwright), author of 'The Miracle Worker. The United States space agency NASA had originally planned to build a miniature rover as part of the Hayabusa mission, but the project, developed by JPL and called Muses-CN, was cancelled in November, 2000, for budgeting reasons. Wilfrid Wilson Gibson. Instead, it joins ranks with the hoppers carried on the failed Soviet Phobos missions, which also never saw use. Thomas Milner Gibson. Had it been successful, MINERVA would have been the first 'space hopper' to see action. Steve Gibson, of Gibson Research, makers of SpinRite. [2] [3] [4].

Gibson. Instead, it escaped Itokawa's gravitational pull and tumbled into space. Robert L. Early inspection of data suggests that mission control is in contact with MINERVA but that it was not successfully dropped onto the asteroid's surface. Gibson. As a result, when the MINERVA release command arrived, MINERVA was released while the probe was ascending and at a higher altitude than intended. Randall L. The lander release command was sent from Earth, but before the command could arrive, Hayabusa's altimeter measured its distance from Itokawa to be 44m and thus started an automatic altitude keeping sequence.

Mel Gibson, film actor, director and producer. MINERVA was deployed on November 12, 2005. Kirk Gibson. This solar-powered, box-shaped vehicle was designed to take advantage of Itokawa's very low gravity by hopping great distances across the surface of the asteroid, relaying images from its cameras to Hayabusa whenever the two spacecraft were in sight of one another.[1]. Jon Gibson (minimalist musician). Unfortunately, an error during deployment resulted in the craft's failure. John Gibson (Indiana). Hayabusa carried a tiny mini-spacecraft (weighing only 591 g) named MINERVA (short for MIcro/Nano Experimental Robot Vehicle for Asteroid).

John Gibson (media host). It will land via parachute near Woomera, Australia. Jill Gibson. The capsule will experience peak deceleration of about 25 G and heating rates approximately 30 times those experienced by the Apollo spacecraft. Jabbar Gibson. This is currently planned for June 2010. Gibson, the American psychologist influential in the field of visual perception. Once it is on its return trajectory, the re-entry capsule will be detached from the main spacecraft at a distance of about 300,000 to 400,000 km from the Earth, and the capsule will coast on a ballistic trajectory, re-entering the Earth's atmosphere.

J. This maneuver was delayed due to problems with attitude control and the thrusters of the craft. J. After a few months in close proximity to the asteroid, the spacecraft was scheduled to fire its engines to begin its cruise back to Earth. Ian Gibson (artist). However, it is currently uncertain whether the metal projectiles were fired during contact. Hutton Gibson. Any samples that were collected are now held inside a separate re-entry capsule.

Hoot Gibson. At the second Hayabusa touchdown with its deployable collection horn, the spacecraft was programmed to fire tiny projectiles at the surface and then collect the resulting spray. Guy Gibson. Autonomous optical navigation was employed extensively during this period because the long communication delay prohibits Earth-based real-time commanding. Gordon Gibson. Afterwards, the spacecraft moved closer to the surface ("home position"), and then approached the asteroid for a series of soft landings and collection of samples at the safest site. Edward Gibson. Hayabusa surveyed the asteroid surface from a distance of about 20 km, the "gate position".

Edmund Gibson. As it arrived, the spacecraft did not go into orbit around the asteroid, but remained in a station-keeping heliocentric orbit close by. Don Gibson. The spacecraft's xenon ion engines (two separate units, each with two exhausts) have been operating near-continuously for the last two years, slowly moving Hayabusa toward a September 2005 rendezvous with Itokawa. Deborah Gibson, is a singer, Broadway performer and former teen idol, credited as Debbie Gibson during her Teen Idol days. Following launch, the spacecraft's name was changed from the original MUSES-C to Hayabusa, the Japanese word for falcon). Colin Gibson. The Hayabusa spacecraft was launched on 9 May 2003 at 04:29:25 UTC on an M-5 rocket from the Uchinoura Space Center (still called Kagoshima Space Center at that time).

Christopher Burke Gibson.
. Chris Gibson (game), fictional race driver. Despite its designer's intention, Hayabusa did land and sit on the asteroid surface for about 30 minutes (see the November 19 entry in the recent events section below). Chris Gibson (Tasmania), Australian politician. However, it is the first craft designed from the onset to make contact with the surface of an asteroid. Gibson. Technically, Hayabusa is not designed to 'land': it simply touches the surface with its sample capturing device and then moves away.

Charles H. In addition, Hayabusa is the first spacecraft designed to deliberately land on an asteroid and then take off again (NEAR Shoemaker made a controlled descent to the surface of 433 Eros in 2000, but it was not designed as a lander and was eventually deactivated after it arrived). Charles Dana Gibson is a famous American graphic artist. Other spacecraft, notably Galileo and NEAR Shoemaker, have visited asteroids before, but the Hayabusa mission, if successful, will mark the first time that an asteroid sample is returned to Earth for analysis. Charles Gibson. . Bob Gibson (musician) was an American folksinger. The spacecraft also carried a detachable mini-lander but it failed to reach the surface (see Minerva mini-lander below).

Bob Gibson was a baseball player. In November 2005, it successfully landed on the asteroid to collect samples, and after technical difficulties with the spacecraft, it is slated to return those samples to Earth by June 2010. Althea Gibson. Having arrived at Itokawa, Hayabusa is studying the asteroid's shape, spin, topography, color, composition, density, and history. Alfred Gibson. The Hayabusa spacecraft, formerly known as MUSES-C (ミューゼスC), was launched on 9 May 2003 and rendezvoused with Itokawa in mid-September 2005. Alexander Gibson. Hayabusa (はやぶさ - peregrine falcon) is an unmanned space mission led by the Japan Aerospace Exploration Agency to collect a sample of material from a small near-Earth asteroid named 25143 Itokawa (dimensions 540 meters by 270 meters by 210 meters) and return the sample to Earth for analysis.

Gibson Desert. June 2010: Hayabusa will release its samples to return to Earth in a re-entry capsule. Gibson, Western Australia – a small village. February 2007: Hayabusa will begin its return to Earth. Gibson, Wisconsin. If it stabilizes to the opposite direction, we'll have to wait longer so that the probe goes around and the sun is then on the other side. Gibson County, Tennessee. If it stabilizes so that the solar cell and the antenna are directed to an appropriate direction, the probe will be powered up and communication will be recovered.

Gibson, Tennessee. January 2006: Precession movement stabilizes to pure rotation around Z-axis. Gibson Township, Michigan. [25] [26]. Gibson, Louisiana. The probability of this is 60% by December 2006, 70% by spring 2007. Gibson County, Indiana. After the stabilization, the rotation axis must be directed toward the Sun and Earth within specific angular range.

Gibson Martini, see Martini cocktail. It will take a month or two to wait for stabilization by conversion of precession to pure rotation. Gibson, to Hack. It is estimated that the turbulence was caused by evaporation of 8 or 10cc of leaked fuel. Gibson Amphitheatre. On December 8, sudden altitude change was observed, and the communication with Hayabusa was lost. Gibson Girl. Due to the power outage, the telemetry log data is faulty, and still needs investigation.

Gibson Appliance. As the result of telemetry analysis, it was found that there is a strong possibility of the projectile of sampler not penetrated when it landed on November 25. Gibson Guitar Corporation. Telemetry was obtained and analyzed. On December 5, attitude was corrected enough to regain communication through the medium gain antenna. Attitude control was commanded using the xenon gas.

On December 4, as an emergency measure, xenon propellant from the ion engines was blown to correct the spin, and it was confirmed successful. On December 3, the probe's Z-axis was found to be 20 to 30 degrees from the sun direction and increasing. On December 2, an attitude correction was tried, but the thruster did not generate enough force. [23] [24] On November 27, the probe experienced a power outage when trying attitude correction, probably due to a fuel leakage.

JAXA held a press conference about the situation so far. On December 6, Hayabusa was 550km from Itokawa. [22]. Mission control is working to resolve the problem before the craft's upcoming launch window for return to Earth.

On November 30, JAXA announced that control and communication with Hayabusa had been restored, but a problem remains with the craft's reaction control system, perhaps involving a frozen pipe. [21]. However, due to a leak in the thruster system, the probe was put in a safe hold mode. This time, the sampling device was activated [20].

On November 25, a second touchdown attempt was performed. This mode did not permit a sample to be taken, but there is a high probability that some dust may have whirled up into the sampling horn when it touched the asteroid, so the sample canister currently attached to the sampling horn was sealed. [19] Unfortunately, the sampling sequence was not triggered since a sensor detected an obstacle during descent; the probe tried to abort the landing, but since its attitude was not appropriate for ascent, it chose instead a safe descent mode. The probe had entered into a safe mode, slowly spinning to stabilize altitude.[17] [18] However, after regaining control and communication with the probe, the data from the landing attempt were downloaded and analyzed, and on November 23, JAXA announced that the probe had indeed landed on the asteroid surface.

Ground control sent a command to abort and ascend, and by the time the communication was regained, the probe had moved 100 km away from the asteroid. It was initially reported that Hayabusa had stopped at approximately 10 meters from the surface, hovering for 30 minutes for unknown reasons. There was considerable confusion during and after the manoeuvre about precisely what had happened, due to the fact that the high-gain antenna of the probe cannot be used during final phase of touch-down, as well as the blackout during handover of ground station antenna from DSN to Usuda station. On November 19, Hayabusa landed on the asteroid.

MINERVA was released but due to an error failed to reach the surface (see above). On November 12, Hayabusa closed in to 55m from the asteroid's surface. [16]. From analysis of the closeup images, the Woomera Desert site (Point B) was found to be too rocky to be suitable for landing so that a landing will now be performed only at the Muses Sea site (Point A) even if the landing is to be performed twice.

After that, Hayabusa backed off to a higher position, then descended again to 500m and released one of the target markers into space to test the craft's ability to track it (this was confirmed). On November 9, Hayabusa performed a descent to 70m to test the landing navigation and the laser altimeter. On November 7, Hayabusa was 7.5 km from Itokawa. [14] [15].

It will take a few days to evaluate the situation and set new schedule. [13] The project manager, Jun-ichiro Kawaguchi, explained that the optical navigation system was not tracking the asteroid very well, probably caused by the complex shape of Itokawa. However, at 1:50 am UTC (10:50 am JST) on November 4, it was announced that due to a detection of an anomalous signal at the Go/NoGo decision, the descent, including release of Minerva and the target marker had been canceled. The descent went well initially, and navigation images with wide-angle cameras were been obtained.

On November 3, Hayabusa began its descent which was to have included delivery of a target marker, and release of the Minerva mini-lander. On November 3, Hayabusa was 3.0 km from Itokawa. [12]. On November 2, JAXA held a press conference about scientific and engineering achievements during proximity operations around Itokawa.

However, it was also announced that the spacecraft's second reaction wheel, governing the Y-axis, had failed, and that it is now being pointed by the craft's rotation thrusters.[11]. Closeup pictures were released. On October 4, JAXA announced that the spacecraft had successfully moved to its 'Home Position' 7 km from Itokawa. On September 15, a 'colour' image of the asteroid was released (which is, however, grey in colouring) [10].

[9]. On September 12, Hayabusa was 20 km from Itokawa and JAXA scientists announced that Hayabusa had officially 'arrived'. [8]. From September 11, individual hills could be discerned on the asteroid.

[7]. From September 4, Hayabusa's cameras were able to confirm Itokawa's elongated shape. On August 28, the orbit maneuver of Hayabusa was handed over from the ion engines to the bi-propellant thrusters. [6].

[5] Other images were taken from August 22 to August 24. The picture was taken by the star tracker and shows a point of light, believed to be the asteroid, moving across the starfield. On August 14, Hayabusa 's first image of Itokawa was released. On July 31, 2005, the X-axis reaction wheel failed.

The November 12 release of the MINERVA mini-probe ended in failure. The original decision to sample two different sites on the asteroid was changed when one of the sites, Woomera Desert, was found to be too rocky for a safe landing. The November 4 'rehearsal' landing on Itokawa failed, and was rescheduled. JAXA claims that since global mapping of Itokawa has been completed, this is not a major problem, but the mission plan was altered.

After the latter failure, the spacecraft is now being turned on the X and Y axes with its thrusters. Two reaction wheels that govern the attitude movement of Hayabusa failed in 2005; the X-axis wheel failed on July 31, and the Y-axis on October 2. Since orbital mechanics dictate that the spacecraft must still leave the asteroid by November, the amount of the time it was able to spend at Itokawa was greatly reduced and the number of landings on the asteroid were reduced from three to two. This reduction in electrical power reduced the efficiency of the ion engines, thus delaying the arrival at Itokawa from June to September 2005.

In 2003, while Hayabusa was en-route to Itokawa, a large solar flare damaged the solar cells aboard the spacecraft. Hayabusa was to deploy a small rover supplied by NASA, called Muses-CN, onto the surface of the asteroid, but the rover was cancelled by NASA in November 2000 due to budget constraints. As a result, the target asteroid was changed from Nereus to Itokawa. However, a July 2000 failure of Japan's M-5 rocket forced a delay in the launch, putting Nereus out of reach.

The spacecraft was originally intended to launch in July 2002 to the asteroid 4660 Nereus.
