ESA selects targets for asteroid-deflecting mission Don Quijote
ESA Homepage ^ | 26 September 2005 | Andrés Gálvez

Posted on 09/26/2005 12:17:31 PM PDT by MHalblaub

Don Quijote is an asteroid investigation , geophysical characterisation and deflection technological experiment mission. The mission will contain the following elements:

* Two spacecraft which are to be launched in separate interplanetary trajectories.

* One spacecraft, which will be referred to as Hidalgo, will impact an asteroid of approximately 500 m diameter at a relative speed of at least 10 km/s.

* The other spacecraft, called Sancho, will arrive earlier at the same asteroid along a very different route, perform a rendez-vous and remain in orbit around the asteroid for several months before and after the impact.

* Sancho will also deliver a number of penetrators to form a seismometernetwork on the asteroid.

* At the time of the impact, Sancho will retreat to a safe distance to observe the impact without taking unnecessary risk (with an attitude appropriate to its name)

* It will later return to a close orbit, to observe the changes in the asteroid internal structure, shape, orbit and rotation state of the asteroid.

Only thing is Quiote was off his rocker and couldn't hit the side of a windmill. Doesn't give much confidence in this mission.

Don Quixote... Sancho and Hidalgo... LOL!

It's nice to know that at least a few Europeans still have a sense of humor.

It's the ESA, so I won't offend too many Freepers if I say that "Hidalgo" and "Sancho" sound like wussy names chosen by committee.

"Don Quijote" - pah! I think a mission to a huge mass of nickel/iron moving at Mach 10 should be called something cool like "Nostromo" or "Heart of Darkness" - they shoul d have used Conrad rather than Cervantes.

Newsday | 4/4/02 | Paul Recer
WASHINGTON -- A new look at an asteroid orbiting the sun shows it could possibly smash into the Earth with the explosive force of millions of tons of TNT. But experts say the potential impact is still 878 years away, time enough for the speeding space rock to alter its course. Named 1950 DA, the asteroid -- six-tenths of a mile wide -- is the most threatening to the Earth of all of the known large asteroids, but the odds are only about one in 300 that it would impact the planet, researchers said Thursday in the journal Science.

Scientists say asteroids' bigger belt is nothing to worry about Astronomers who found there are twice as many asteroids near Mars as previously thought say there is still little chance of one colliding with Earth. The latest estimates show there are up to 1.9 million asteroids within the main asteroid belt. Scientists haven't worked out the orbit of every rock but believe they rarely change direction and so are unlikely to hit us. Astronomers used the European Space Agency's Infrared Space Observatory to look at part of the asteroid belt and then estimated the total number there. Edward Tedesco of...

LONDON (Reuters) - A massive asteroid could hit Earth in just 17 years' time, destroying life as we know it, a British space expert said Wednesday. The asteroid -- the most threatening object ever detected in space -- is 1.2 miles wide and apparently on a direct collision course with Earth.

Sydney Morning Herald | July 25 2002
An asteroid which could hit the Earth in 17 years time should be blown away with a nuclear weapon, an Australian astronomer said today. If left untouched the asteroid could plummet to Earth, causing tidal waves and mayhem. The best way to ensure it was diverted was to put a nuclear weapon beside it and blow it out of orbit, Stromlo Observatory astronomer Vince Ford said. Scientists are still trying to determine whether the asteroid, known by NASA as 2002 NT7, will hit the Earth in 2019. NASA says it is still too early to tell whether the remote possibility...

Next month a newly discovered asteroid will pass close enough to Earth to be easily spotted in small telescopes and even binoculars. According to calculations by Gareth V. Williams, associate director of the Minor Planet Center in Cambridge, Massachusetts, the asteroid's August 18th flyby should bring it to within 530,000 kilometers (330,000 miles) of Earth, just outside the Moon's orbital distance. Astronomers first detected this object, designated 2002 NY40, on July 14th with the 1-meter LINEAR telescope in New Mexico. Thus it was picked up a full month before brushing by Earth, unlike asteroid 2002 MN, whose pass well inside...

Hollywood dispatched Bruce Willis and an arsenal of nuclear bombs, but the simplest way to save Earth from a monster asteroid may be to inflate a giant air bag and nudge the killer rock out of the way, an American scientist says. Dr. Hermann Burchard suggests an air pillow as much as a few kilometres wide, inflated in space and steered by a spacecraft, could apply enough pressure to push an asteroid or comet out of Earth's path and prevent mass death and destruction. Experts have lately been warning that a cataclysmic collision by cosmic debris, obliterating a whole continent...

A metallic asteroid may have coincided with the fall of Rome, says Duncan Steel Thursday February 6, 2003 The Guardian In the early fifth century, rampaging Goths swept through Italy. Inviolate for 1,100 years, Rome was sacked by the hordes in 410 AD. St Augustine's apologia, the City of God, set the tone for Christians for the next 16 centuries. But the Rome of that era came close to suffering a far worse calamity. A small metallic asteroid descended from the sky, making a hypervelocity impact in an Apennine valley just 60 miles east of the city. This bus-sized lump...

Suppose a giant asteroid is heading toward Earth right now. Impact is certain. The consequences are expected to be globally devastating, with the human race among the casualties. The chances of doing anything about it are zero, the government decides. Would you want to know? Or would you prefer the Feds keep the information secret and spare you and your neighbors a bunch of pointless worrying? In essence, the question concerns whether you'd prefer to die in ignorant bliss, or if you'd like some options. The alternatives might include dying in a panic, calmly making peace with your Maker, finally...

ODD ASTEROID: On April 7th, astronomers discovered a near-Earth asteroid following a curious path around the Sun. The orbit of 2003 GQ22 is nestled almost entirely inside Earth's own. "2003 GQ22 is nearly a member of the elusive inner-Earth object group, for which there is thought to be several members, but only one discovered to date (2003 CP20)," says Donald Yeomans, the manager of JPL's Near Earth Object Program. Inner-Earth asteroids start out like most space rocks--orbiting the Sun in the asteroid belt beyond Mars. But over the course of time, perhaps hundreds of millions of years or longer, they...

Astronomers have been so horrified by press scares over asteroids that they are toning down the scale they use to rate the threat posed in an attempt to discourage journalists from covering potential collisions. The most prominent recent furore involved asteroid QQ47, which briefly had a one-in-a-million chance of crashing into our planet in 2014. Some astronomers even want the way asteroids are assessed to be completely overhauled. The Torino scale, developed in 1999 by Rick Binzel of the Massachusetts Institute of Technology, is used to inform the public about potential impacts. It rates an asteroid's threat on a scale...

The good news is that its next fly-by, on 4 November, will miss the Earth by a relatively comfortable seven million kilometres. Asteroid 1937 UB, later dubbed Hermes, set a record for closest recorded approach to the Earth on 30 October 1937. The record lasted for 50 years. Hermes is one to two kilometres in diameter and would cause global devastation if it hit the planet. So, given...

Astronomers have apparently discovered an interesting twist to one of the greatest asteroid mysteries of all time. Hermes, a space rock lost to science for 66 years and recently rediscovered, could actually be a pair of orbiting asteroids, new radar observations suggest. Hermes had not been seen since its 1937 discovery until found anew in a collaborative effort last week. Once Hermes was recovered, astronomers around the world began observing it to take advantage of its relative proximity. The latest look at Hermes, also named 1937 UB, comes from the Arecibo Observatory in Puerto Rico. The radar observations were made...

Washington-AP -- New research casts doubt on the theory that a single asteroid wiped out the dinosaurs. Scientists have often pointed to a crater in Mexico as the asteroid's impact point. But Princeton University researchers say the impact that caused the crater occurred 300-thousand years before the dinosaurs were wiped out 65 (m) million years ago. A report appears in this week's online edition of Proceedings of the National Academy of Sciences. At least one scientist doubts the group's findings. Richard Norris of the Scripps Institution of Oceanography says the Princeton researchers were working with incorrect site data.

Reuters | Mon Mar 1, 2004 | Maggie Fox
Scientists probing a vast crater off Mexico's Yucatan peninsula questioned a popular theory about dinosaurs on Monday, saying the collision that formed the crater happened too far back in time to have caused their extinction by itself. Much evidence points to the idea that an asteroid or comet gouged the Earth around 65 million years ago, triggering volcanic and climate changes that eventually wiped out the dinosaurs. When the huge, mostly underwater crater was found off Yucatan, it seemed the perfect candidate. "Since the early 1990s the Chicxulub crater on Yucatan, Mexico, has been hailed as the smoking gun that...

Dino impact gave Earth the chill A cloud of sulphate particles may have blocked out the sun's warmth Evidence has been found for a global winter following the asteroid impact that is thought to have killed off the dinosaurs 65 million years ago. Rocks in Tunisia reveal microscopic cold-water creatures invaded a warm sea just after the space rock struck Earth. The global winter was probably caused by a pollutant cloud of sulphate particles released when the asteroid vapourised rocks at Chicxulub, Mexico. The results are reported in the latest issue of the journal Geology. Italian, US and Dutch...

According to new research led by a University of Colorado at Boulder geophysicist, a giant asteroid that hit the coast of Mexico 65 million years ago probably incinerated all the large dinosaurs that were alive at the time in only a few hours, and only those organisms already sheltered in burrows or in water were left alive. The six-mile-in-diameter asteroid is thought to have hit Chicxulub in the Yucatan, striking with the energy of 100 million megatons of TNT, said chief author and Researcher Doug Robertson of the department of geological sciences and the Cooperative Institute for Research in Environmental...

The craters may have either come from an asteroid between 5 and 11km across that broke up in the atmosphere, a swarm of comets or comet fragments. The space impacts created multiple craters over an area of 2,092km (1,300 miles) by 3,862km (2,400 miles).

http://neo.jpl.nasa.gov Impact Probability The calculation of impact probability involves the disciplines of orbital dynamics, estimation theory, and numerical analysis. The orbit of a comet or asteroid is determined from a set of observations (right ascension/declination coordinates). The observations are typically accurate to 0.5 arc-sec, although this can vary somewhat according to the pixel size used in the CCD detectors: some observatories have only 1.0 arc-sec accuracy. Because there are some errors in the observations, there will be uncertainties in the orbital determination for the object. The uncertainty in the orbital elements also depends on the number of observations and the...

Humans live in a vast solar system where 2,000 feet seems a razor-thin distance. Yet it's just wide enough to trigger concerns that an asteroid due to buzz Earth on April 13, 2029 may shift its orbit enough to return and strike the planet seven years later. The concern: Within the object's range of possible fly-by distances lie a handful of gravitational "sweet spots," areas some 2,000 feet across that are also known as keyholes. The physics may sound complex, but the potential ramifications are plain enough. If the asteroid passes through the most probable keyhole, its new orbit would...

The orbit maneuver of HAYABUSA spacecraft was handed over from the ion engines to the bi-propellant thrusters on August 28 JST. After the solar conjunction the microwave discharge ion engines were turned on again at the end of July and accelerated with their full throttling so as to approach to the target. At the end of August HAYABUSA stays 4,800km (3,000 mi.) apart from Asteroid ITOKAWA and is still closing it at 32km/h (20 mph) velocity with the ion engines off. HAYABUSA asteroid explorer, launched on May 9 2003, has executed the orbit maneuver using the microwave discharge ion engines,...

What a powerful telescope had picked up as it stretched towards the night sky over Antarctica was the trail of dust left in the wake of the death of an asteroid... "What he didn't know at the time was that seven hours earlier an asteroid had crashed to Earth in another part of Antarctica, about 1500 kms west of Davis. The closest it got to human habitation was around 900 kms west of Japan's Syowa station," Dr Klekociuk said... Dr Klekociuk said that it was thought that the asteroid had come from what is known as the Aten group somewhere...

Government officials are evaluating and revising disaster plans around the United States in the wake of Hurricane Katrina, just as they did after the Sept. 11 terrorist attacks. While war and automobiles kill more people than nature, find out what natural disasters top scientists’ worry lists. #10 Pacific Northwest Megathrust Earthquake Geologists know it’s just a matter of time before another 9.0 or larger earthquake strikes somewhere between Northern California and Canada. The shaking would be locally catastrophic, but the biggest threat is the tsunami that would ensue from a fault line that’s seismically identical to the one that...

Icy world found inside asteroid Ron Cowen New observations of Ceres, the largest known asteroid, suggest that frozen water may account for as much as 25 percent of its interior. If this is true, the volume of ice on Ceres would be greater than that of all the fresh water on Earth. CERES SERIES. This sequence of Hubble images reveals a bright spot of unknown origin on Ceres during a quarter-turn of the asteroid's 9-hour rotation. Thomas, et al., NASA The evidence comes from Hubble Space Telescope images showing that the 930-kilometer-wide asteroid is smooth and almost perfectly round. Simulations...

An asteroid the size of two football fields could wipe out a large city or set off a series of tsunamis across the world. The threat of such an Earth-smashing asteroid has lead scientists to dream up several methods of defending the planet against such a catastrophe. Solutions have ranged from pushing the asteroid with a spacecraft to mounting a thruster on its surface. But pushing it would require too much fuel and could break up the asteroid. Also, asteroids rotate, which could complicate the firing of a surface thruster. Now, two NASA astronauts have presented a plan for an...

Japan's Hayabusa spacecraft is on track to attempt a sampling of asteroid Itokawa on November 19. In a rescheduled practice run on November 9, the craft has approached within 230 feet (70 meters) of the asteroid during a descent test that verified the probe's guidance and navigation functions. Engineers handling the Hayabusa spacecraft have clarified the issues that led to the cancellation of a November 4 landing rehearsal. An onboard navigation computer detected anomalous information during the practice run. The problem resulted in an abort command being transmitted to the probe by Earth controllers, thereby stopping the rehearsal. Subsequently, the...

Japanese space probe Hayabusa may have failed to land on the asteroid Itokawa, located about 290 million kilometers away from the Earth, Japan's space agency said Sunday. The Japan Aerospace Exploration Agency said it is uncertain whether Hayabusa has landed on the asteroid, adding the probe is apparently moving upward after hovering around 10 meters away from the small celestial body. The agency said the spacecraft, which temporarily lost contact with it, may have faced some sort of operational trouble. The probe dropped a ball with a reflecting plate as a landing target from about 40 meters above the...

TOKYO - A Japanese space probe is heading back toward an asteroid for a second landing attempt after failing to touch down over the weekend, space agency officials said Monday. Communications between the Hayabusa probe and Japan's space agency, JAXA, have returned to normal after the vessel inexplicably stopped just yards from the asteroid Itokawa on Sunday. The probe, which also botched a rehearsal earlier this month, is on a mission to briefly land on the asteroid, collect material, then bring it back to Earth. Officials will analyze data from the probe Tuesday to find out what went wrong in...

In Egyptian myth, Apophis was the ancient spirit of evil and destruction, a demon that was determined to plunge the world into eternal darkness. A fitting name, astronomers reasoned, for a menace now hurtling towards Earth from outerspace. Scientists are monitoring the progress of a 390-metre wide asteroid discovered last year that is potentially on a collision course with the planet, and are imploring governments to decide on a strategy for dealing with it.

Asteroid sampling mission probably failed 16:01 07 December 2005 NewScientist.com news service Maggie McKee and AFP The Japanese spacecraft Hayabusa is likely to have failed in its landmark mission to collect the first-ever samples from an asteroid, mission officials said on Wednesday. It also faces trouble returning to Earth. The Japan Aerospace Exploration Agency (JAXA) had earlier said the Hayabusa probe "most probably" succeeded in gathering material from the Itokawa asteroid, 290 million kilometres from Earth, on 26 November. The spacecraft was thought to have landed on the space rock for just one second, firing two metal pellets to throw...

LONDON — Scientists are monitoring the progress of a 390m-wide asteroid discovered last year that is potentially on a collision course with the planet, and are imploring governments to decide on a strategy for dealing with it. The National Aeronautics and Space Administration has estimated that an impact from Apophis, which has an outside chance of hitting the Earth in 2036, would release more than 100,000 times the energy released in the nuclear blast over Hiroshima. Thousands of square kilometres would be directly affected by the blast but the whole of the Earth would see the effects of the dust...

Any action that might possibly be taken to divert a 390m-wide asteroid from colliding with Earth is likely to be opposed by environmentalists. The reasons range from reluctance to tampering with Mother Nature to the belief that anything that might destroy civilization would be good for the environment. The asteroid in question is Apophis, which has an outside chance of hitting the Earth in 2036. The impact would release more than 100,000 times the energy released in the nuclear blast over Hiroshima. The Earth would see massive cooling effects from the dust released into the atmosphere. There has been some...
