On December 25, 2003, a British-built lander dropped to the Martian surface and disappeared without a trace. Now we know what happened to it. It's hard to overstate how valuable the main camera aboard the Mars Reconnaissance Orbiter has been. The craft's High-Resolution Imaging Science Experiment, or HiRISE, uses a 20-inch (0.5-m) f/24 telescope to record details on the Martian surface as small as 0.3 m (about 10 inches).
Primarily it's a powerful tool for studying Martian geology at the smallest scales, and NASA scientists sometimes use it to track the progress (and even the arrivals) of their rovers. Beagle 2 on Mars The clamshell-like Beagle 2 lander weighed just 30 kg, but it was well equipped to study Martian rocks and dust — and even to search for life. Beagle 2 consortium But the HiRISE team has also been on a years-long quest to find the remains of Beagle 2, a small lander that had hitchhiked to the Red Planet with the European Space Agency's Mars Express orbiter. It descended to the Martian surface on Christmas Day in 2003 and was never heard from again. Space aficionados have debated its fate ever since. Did parachute failure lead to a crash landing? Did strong surface winds flip the saucer-shaped craft upside down? Did the Martians take it hostage? Now, thanks to HiRISE, we know more of the story.
Images taken in February 2013 and June 2014 of the landing area in Isidis Planitia showed promising blips near the edge of each frame. A follow-up color view, acquired on December 15th and released three days ago, show a bright spot consistent with Beagle 2. The fully-opened lander would have been less than 2 m (6½ feet) across, so the craft is only barely resolved. Apparently the spacecraft made it to the surface intact, opened its clamshell cover, and had partially deployed its four petal-shaped solar-cell panels before something went awry.

One encouraging clue is that the bright reflection changes position slightly from image to image, consistent with sunlight reflecting off different lander panels. Two other unusual spots a few hundred meters away appears to be the lander's parachute and part of the cover that served as a shield during the 5½-km-per-second atmospheric descent...

The initial images didn't just show up. They'd been requested and searched by Michael Croon of Trier, Germany, who'd served on the Mars Express operations team. Croon had asked for specific camera targeting through a program called HiWish, through which anyone can submit suggestions for HiRISE images. Read more about this fascinating sleuthing story.
"Not knowing what happened to Beagle 2 remained a nagging worry," comments Rudolf Schmidt in an ESA press release about the find. "Understanding now that Beagle 2 made it all the way down to the surface is excellent news." Schmidt served as the Mars Express project manager at the time.
Built by a consortium of organizations, Beagle 2 was the United Kingdom's first interplanetary spacecraft. The 32-kg (73-pound) lander carried six instruments to study geochemical characteristics of the Martian surface and to test for the presence of life using assays of carbon isotopes. It was named for HMS Beagle, the ship that carried a crew of 73 (including Charles Darwin) on an epic voyage of discovery in 1831–36.

NASA’s Dawn spacecraft is approaching the dwarf planet Ceres and new images released Monday show a closer view of the planet’s surface.
"We know so much about the solar system and yet so little about dwarf planet Ceres. Now, Dawn is ready to change that," said Marc Rayman, Dawn's chief engineer and mission director, according to a news release from NASA's Jet Propulsion Laboratory.
The NASA spacecraft is scheduled to conduct a 16-month study of Ceres and will send increasingly better and better images as it gets closer to the planet. It is the first time a spacecraft has ever visited a dwarf planet.
"Already, the [latest] images hint at first surface structures such as craters," said Andreas Nathues, lead investigator for the framing camera team at the Max Planck Institute for Solar System Research, Gottingen, Germany.
The images, taken by Dawn 238,000 miles from Ceres on January 13, are at about 80 percent the resolution of Hubble Space Telescope images taken in 2003 and 2004. The next set of images to be released by Dawn – at the end of January – will be the clearest yet, NASA says.
Ceres, which lies between Mars and Jupiter, has an average diameter of 590 miles and is the largest body in the main asteroid belt. It is believed to contain a large amount of ice and scientists say the surface of the planet could be concealing an ocean.
"The team is very excited to examine the surface of Ceres in never-before-seen detail," said Chris Russell, principal investigator for the Dawn mission. "We look forward to the surprises this mysterious world may bring."
The Dawn spacecraft has already delivered more than 30,000 images of Vesta – the second largest body in the main asteroid belt – during an orbit in 2011 and 2012.

Researchers have decoded ancient recordings from fragments of an asteroid dating back billions of years to the start of the Solar System.
Like the data recorded on the surface of a computer hard drive, the magnetic signals written in the space rock reveal how Earth's own metallic core and magnetic field may one day die.
The work appears in Nature journal.
Using a giant X-ray microscope, called a synchrotron, the team was able to read the signals that formed more than four-and-a-half billion years ago, soon after the birth of the Solar System.
It's like a cosmic archaeological mission”Dr James Bryson University of Cambridge
The meteorites are pieces of a parent asteroid that originally came from asteroid belt, between Mars and Jupiter.They represents the left-over fragments of a planet that failed to form. The magnetic recording within it traps a signal of the precise moments when an iron-rich core formed in the asteroid as well as when it froze, killing its magnetic field.
The new picture of metallic core solidification in the asteroid provide clues about the magnetic field and iron-rich core of Earth.
Core values "Ideas about how the Earth's core evolved through [our planet's] history are really changing at the moment," lead researcher Dr Richard Harrison, from the University of Cambridge, told BBC News.
"We believe that Earth's magnetic field is linked to core solidification. Earth's solid inner core may have started to form at very interesting time in terms of the evolution of life on Earth.
"By studying an asteroid we get to see this in fast forward. We can see the start of core solidification in the magnetic records as well as its end, and start to think about how these processes work on Earth."
Tiny particles, smaller than one thousandth the width of a human hair, trapped within the metal have retained the magnetic signature of the parent asteroid from its birth in the early Solar System.
"We're taking ancient magnetic field measurements in nano-scale materials to the highest ever resolution in order to piece together the magnetic history of asteroids - it's like a cosmic archaeological mission," said Dr James Bryson, the paper's lead author.
"Since asteroids are much smaller than Earth, they cooled much more quickly, so these processes occur on a shorter timescales, enabling us to study the whole process of core solidification."
Prof Wyn William, from the University of Edinburgh, who was not involved in the study, commented: "To be able to get a time stamp on these recordings, to get a cooling rate and the time of solidification, is fantastic. It's a very nice piece of work."
The key to the long-lived stability of the recording is the atomic-scale structure of the iron-nickel particles that grew slowly in the asteroid core and survived in the meteorites.
Making a final comment on the results, Dr Harrison said: "In our meteorites we've been able to capture both the beginning and end of core freezing, which will help us understand how these processes affected the Earth in the past and provide a possible glimpse of what might happen in the future."

The following statement has been posted by Tedstaff at blog.ted.com: "After due diligence, including a survey of published scientific research and recommendations from our Science Board and our community, we have decided that Graham Hancock’s and Rupert Sheldrake’s talks from TEDxWhitechapel should be removed from distribution on the TEDx YouTube channel... All talks on the TEDxTalks channel represent the opinion of the speaker, not of TED or TEDx, but we feel a responsibility not to provide a platform for talks which appear to have crossed the line into pseudoscience.
Response to the TED Scientific Board’s Statement
March 18, 2013
I would like to respond to TED’s claims that my TEDx talk “crossed the line into pseudoscience”, contains ”serious factual errors” and makes “many misleading statements.”
This discussion is taking place because the militant atheist bloggers Jerry Coyne and P.Z. Myers denounced me, and attacked TED for giving my talk a platform. I was invited to give my talk as part of a TEDx event in Whitechapel, London, called “Challenging Existing Paradigms.” That’s where the problem lies: my talk explicitly challenges the materialist belief system. It summarized some of the main themes of my recent book Science Set Free (in the UK called The Science Delusion). Unfortunately, the TED administrators have publically aligned themselves with the old paradigm of materialism, which has dominated science since the late nineteenth century.
TED say they removed my talk from their website on the advice of their Scientific Board, who also condemned Graham Hancock’s talk. Hancock and I are now facing anonymous accusations made by a body on whose authority TED relies, on whose advice they act, and behind whom they shelter, but whose names they have not revealed.
TED’s anonymous Scientific Board made three specific accusations:
Accusation 1:“he suggests that scientists reject the notion that animals have consciousness, despite the fact that it’s generally accepted that animals have some form of consciousness, and there’s much research and literature exploring the idea.”
I characterized the materialist dogma as follows: “Matter is unconscious: the whole universe is made up of unconscious matter. There’s no consciousness in stars in galaxies, in planets, in animals, in plants and there ought not to be any in us either, if this theory’s true. So a lot of the philosophy of mind over the last 100 years has been trying to prove that we are not really conscious at all.” Certainly some biologists, including myself, accept that animals are conscious. In August, 2012, a group of scientists came out with an endorsement of animal consciousness in “The Cambridge Declaration on Consciousness”. As Discovery News reported, “While it might not sound like much for scientists to declare that many nonhuman animals possess conscious states, it’s the open acknowledgement that’s the big news here.” (http://news.discovery.com/
But materialist philosophers and scientists are still in the majority, and they argue that consciousness does nothing – it is either an illusion or an ”epiphenomenon” of brain activity. It might as well not exist in animals – or even in humans. That is why in the philosophy of mind, the very existence of consciousness is often called “the hard problem”.http://en.wikipedia.
Accusation 2:“He also argues that scientists have ignored variations in the measurements of natural constants, using as his primary example the dogmatic assumption that a constant must be constant and uses the speed of light as example.… Physicist Sean Carroll wrote a careful rebuttal of this point.”
TED’s Scientific Board refers to a Scientific American article that makes my point very clearly: “Physicists routinely assume that quantities such as the speed of light are constant.”
In my talk I said that the published values of the speed of light dropped by about 20 km/sec between 1928 and 1945. Carroll’s “careful rebuttal” consisted of a table copied from Wikipedia showing the speed of light at different dates, with a gap between 1926 and 1950, omitting the very period I referred to. His other reference (http://micro.magnet.fsu.edu/
In my talk I suggest how a re-examination of existing data could resolve whether large continuing variations in the Universal Gravitational Constant, G, are merely errors, as usually assumed, or whether they show correlations between different labs that might have important scientific implications hitherto ignored. Jerry Coyne and TED’s Scientific Board regard this as an exercise in pseudoscience. I think their attitude reveals a remarkable lack of curiosity.
Accusation 3:“Sheldrake claims to have “evidence” of morphic resonance in crystal formation and rat behavior. The research has never appeared in a peer-reviewed journal, despite attempts by other scientists eager to replicate the work.”
I said, “There is in fact good evidence that new compounds get easier to crystallize all around the world.” For example, turanose, a kind of sugar, was considered to be a liquid for decades, until it first crystallized in the 1920s. Thereafter it formed crystals everyehere. (Woodard and McCrone Journal of Applied Crystallography (1975). 8, 342). The American chemist C. P. Saylor, remarked it was as though “the seeds of crystallization, as dust, were carried upon the winds from end to end of the earth” (quoted by Woodard and McCrone).
The research on rat behavior I referred to was carried out at Harvard and the Universities of Melbourne and Edinburgh and was published in peer-reviewed journals, including the British Journal of Psychology and the Journal of Experimental Biology. For a fuller account and detailed references see Chapter 11 of my book Morphic Resonance (in the US) / A New Science of Life (in the UK). The relevant passage is online here: http://sciencesetfree.tumblr.
The TED Scientific Board refers to ”attempts by other scientists eager to replicate the work” on morphic resonance. I would be happy to work with these eager scientists if the Scientific Board can reveal who they are.
This is a good opportunity to correct an oversimplification in my talk. In relation to the dogma that mechanistic medicine is the only kind that really works, I said, “that’s why governments only fund mechanistic medicine and ignore complementary and alternative therapies.” This is true of most governments, but the US is a notable exception. The US National Center for Complementary and Alternative Medicine receives about $130 million a year, about 0.4% of the National Institutes of Health (NIH) total annual budget of $31 billion.
Obviously I could not spell out all the details of my arguments in an 18-minute talk, but TED’s claims that it contains “serious factual errors,” “many misleading statements” and that it crosses the line into “pseudoscience” are defamatory and false.
