NASA: Claims of Life on Mars Positively False


	_______________________

This story was updated at 5:56 p.m. ET.

Despite new media reports that NASA found justification forlife on Mars, the U.S. space group says explanation that we are not alone is still aways off.

A Wednesday essay in the U.K.s The Sunnewspaper entitled, NASA: Evidence of Life on Mars, reported thatthey group had denounced constrained justification for Martianorganisms. But NASA officials and maestro Mars mission scientists sayno.

This title is intensely misleading, pronounced DwayneBrown, a orator for NASA shaped at the agencys domicile in Washington,D.C. This creates it receptive to advice similar to we voiced that we found hold up on Mars,and that is absolutely, definitely false.

The square claimed that the MarsExploration Rovers Spirit and Opportunity, that have been wheeling aroundthe aspect of the red world given Jan 2004, found pool scum, that thepaper calls the construction blocks of hold up as we know it.

I think they have taken this things out ofcontext, Brown said.

Such a find would indeed have been groundbreaking, sincepond scum, scientifically well known as cyanobacteria, are essentially a form of lifethemselves, not usually construction blocks for it.

I can usually pretence that the Sun reportermisunderstood, pronounced Cornell University heavenly scientist Steve Squyres,principal questioner of the Mars Exploration Rover project, who was quoted inthe story. What Spirit and Opportunity have found is sulfate minerals...not organic materials, not pool scum, and not the construction blocks of hold up as weknow it.

Water = life?

The article, that has been at large quoted opposite the Web,appeared after NASA scientists spoke to reporters from an astrobiologyconference celebrating the 50th anniversary of investigate directed toward searchingfor lifebeyond Earth.

The square claims, The new missions have gatheredevidence of sulphates on Mars, a clever denote there is H2O on the planetand thus life.

But usually since there competence be H2O does not meant thatlife follows.

Evidence of H2O does NOT meant that there waslife, Squyres wrote in an email. We hold that H2O isnecessary for life, but not that it is enough to assure life. The...and thus hold up piece of the matter thus is simplywrong.

While scientists have not nonetheless detected explanation of livingthings anywhere in the star over Earth, they are removing closer toknowing where to see and how to commend the signs of hold up if they arepresent.

And Brown pronounced that NASAs assorted Mars missions, includingthe rovers and booster such as the Mars Reconnaissance Orbiter and the 2001Mars Odyssey � both now in circuit around the red world � are divulgence awealth of clues about the probability of hold up there. Its usually as well shortly to knowfor certain.

Past hold up controversies

Claims of anticipating hold up on Mars are not new.

In Aug 1996 NASA researchers presented a Martian rockthat they pronounced showed transparent signs of being influenced by life. The rock, whichhad landed in Antarctica, contained holes and markings that appeared to havebeen shaped by bacterial colonies vital on it.

The proclamation done a outrageous splash, but in the decade thatfollowed, majority researchers have discharged the claims of life, and foundnonliving explanations for the rocks markings.

There has further been debate over pronouncements thatMars could not presumably bay life. In 1976, NASAs Viking 1 and 2 landerstouched down on the Martian aspect and achieved 3 apart experiments tosearch for signs of life. Despite carrying sensitivities to acknowledge organicmolecules of a couple of tools per billion, no organic compounds were ever detectedby possibly lander. Many scientists spoken that Mars thus contingency not havemicrobial organisms on the surface.

Yet a morerecent investigate found that maybe the Viking experiments were not sosensitive after all, and expel disbelief on the end that microbes aren"tthere.

Besides Mars, a little quite earnest spots in the solarsystem embody the Saturnianmoons Titan � with the lakes of methane and ethane � and Enceladus, withits plumes of H2O vapor, and Jupiters moon Europa, that is thought toharbor an subterraneous ocean.

Experimental X37B Robot Space Plane to Launch Thursday


	_______________________

TheUnited States Air Force plans to launch the initial robotic X37B space craft Thursdayon a mission that is a foregoer of things to come. A second minispace planeis already underneath stipulate and is projected to be launched subsequent year.

Newdetails per the minispaceplane and the arriving Thursday liftoff atop an Atlas 5 upholder werediscussed currently during a U.S. Air Forceheld media press briefing.

TheX37B vehicles story stretches behind to the late 90s, with NASA kickstartingthe project. It was after picked up by the Defense Advanced Research ProjectsAgency (DARPA) and in conclusion found a home inside of the Air Force. The plan isnow underneath the wing of the Air Force Rapid Capabilities Office. [X37Bspacecraft photos.]

"Aftera scattered story of sponsorship, the good to see the X37 eventually get tothe launch desk pad and get in to space," pronounced Gary Payton, U.S. Air Force DeputyUnder Secretary for Space Programs in a media press lecture today.

Autopilotmode

Thesmall X37B booster resembles a tiny space convey and is versed withits own cargo brook about the distance of a pickup lorry bed � plenty space to holda integrate of small satellites that are a couple of hundred kilograms each, Payton noted.

Accordingto expelled specifications, the X37Bspace craft weighs about 11,000 pounds and is usually over twenty-nine feet in length.It stands somewhat some-more than 9 1/2 feet in tallness and has a wingspan usually over14 feet across.

Theinitial X37B moody is created to loaf in space up to 270 days. Afterretracting the solar form and shutting cargo doors, the space craft would reenterin programmed mode.

"It"son autopilot, literally, the complete time the rest of the approach in," Payton told, adding that the Air Force is ready in box the spacecraftmalfunctions. "We"ll be tracking it over the Pacific...and it does have adestruct resource on it.

TheX37B is created to have an unconstrained alighting at Vandenberg Air Force Base inCalifornia, or at adjacent Edwards Air Force Base as backup.

"Similarto the shuttle, it"ll take halftheworld to come home," promissory note on redundantdigital moody carry out systems on the vehicle, Payton said. I"ve got alot of certainty in the capacity of this bird to come behind home autonomously.

Onorder: second space plane

Paytonsaid the X37B space craft provides a new approach for the Air Force to conductonorbit experiments. More critical is experience gained in discerning turnaroundof the returned vehicle, the honing of lowcost operations and maintenanceexpertise, as well as heightening cargo changeout skills, he added

Fastturnaround of X37B, Payton told , could be totalled in multiform daysto 10 to fifteen days or less. "I"d similar to to see this X37 rubbed most some-more similar to anairplane," he said, contrast that capacity to the SR71, an advanced, longrange,Mach 3 and faster vital reconnaissanceaircraft.

Thenew unmanned space craft will exam a new collection of reusable technologies,including new silica reentry tiles, as well as "other technologies that aresort of one era over the shuttle," Payton said.

Alreadyon sequence is a second minispace plane.

"Wedo have a second tail series on contract. Currently, we"re seeking at a 2011launch for that second tail number. That assumes all goes scrupulously aspredicted on this initial flight," Payton said.

Additionalcopies of the minispace craft "depends on success of these initial dual birds," hetold , and if operations and upkeep costs are low and fastturnaround times are achieved.

Classifiedbudget

TheX37B beginning leverages endless and early NASA, DARPA, Air Force, as wellas investments by the builder � Boeing Phantom Works. The appropriation turn for theoverall plan is inside of the Air Forces personal budget, explained AngieBlair, an Air Force mouthpiece for the plan in an progressing interview.

According toinformation expelled by the U.S. Air Force, the X37BOrbital Test Vehicle (OTV) will yield a stretchable space exam height toconduct assorted experiments and concede heavenly body sensors, subsystems, componentsand compared record to be well ecstatic to and from the spaceenvironment where it will need to function.

The X37B will alsoprove new record and components prior to they are committed to operationalsatellites.

The OTV is the initial car given NASAs convey orbiter that has the abilityto lapse experiments to Earth for serve investigation and analysis.

Experimental testplatform

"The X37B is the usually selfcontained bid dictated to be an economicallyviable initial exam height onorbit for months at a time and thenreturn," pronounced David Hamilton Jr., the Air Force Rapid Capabilities officedirector in a not long ago expelled essay by the Air Force.

Hamilton explained the X37B is a risk rebate car for spaceexperimentation that explores concepts of operation for a longduration,reusable space vehicle.

Hamilton explained that the OTV has the intensity "to change how the AirForce operates in space by creation space operations some-more aircraft similar to andadding in the capacity for returnable plugandplay experiments."

A association orator said: This investment builds on the prolonged tenure plans for the UK as we need to use intensity clients who need hit centre imagination in the UK.

Middlesbrough Mayor Ray Mallon said: It is good headlines that Firstsource has recognized Middlesbrough as the preferred place for the ultimate proviso in their expansion. The origination of 300 jobs in the initial instance, and a serve 200 jobs in the destiny will have a poignant stroke on the town.

Ian Williams, of informal growth group One North East, that has since a accede to of �1.9 million for the project, said: This is a genuine opinion of certainty by Firstsource in the North East economy. They recognize the capability of the Tees Valleys workforce to yield glorious services for their clients.

I am gay that One North East has been means to await this plan with financial as well as a good understanding of superintendence and await from the investment and aftercare team.

We need to speak about reticent well read awards


	_______________________

When Lionel Shriver won the Orange Prize for Fiction, she thanked organisers unreservedly for the approval that had eluded her for decades; she had created 7 catastrophic novels and her eighth had been deserted by thirty publishers prior to apropos a word-of-mouth hit.

Nowadays, her attribute to the esteem is far some-more critical. Having scooped the main esteem in 2005 for her novel about demure motherhood, We Need To Talk About Kevin, she has now won an additional fame for the same book by being voted by the open as their prime Waterstones/Orange leader of winners over the past fifteen years. But, rather than purgation onward thanks, she complained that the mixed inlet of the Orange Prize was reticent and widely separated the stroke of winning.

Speaking to The Independent about the shortcomings of the edition industry and mixed prizes by the same organisers, she said: I"m vicious of the Orange people on this front. The some-more prizes you give, the some-more incomprehensible they become. Its a foolish thing to have some-more than one winner; the diluting and it equates to nobody wins.

To symbol the 15th anniversary of the Orange Prize, a girl row picked Anne Michaels" Fugitive Pieces as the prime winner. This years Orange Prize for Fiction and Award for New Writers winners are voiced tonight.

Shriver additionally dismissed a handbill opposite the edition industry, observant she was ripped about recommending essay as a career to determined novelists.

I"m really sensitive to competitor writers. Its really formidable and there are no guarantees that thickk thickk cream will ever climb to the top, she said.

It"d be all false to daunt people from fasten my profession, that was great to me in the end, but I have qualms about being encouraging. The contingency are built opposite you. I wish to give people sufficient of an thought of the capriciousness of the industry.

She went on to expel aspersions on the successes of a little best-selling authors whose essay was simply not really good, she thought, but whose books were aided by the great of the absolute edition broadside appurtenance citing Bret Easton Ellis" ultimate book, Imperial Bedrooms, as one such example.

There are a lot of books that finish up offered that arent really good. I"ve only examination Bret Easton Ellis" new book and the horrible but the had a big broadside campaign.

I"m essay a 1,500 word examination of it the distance of that alone will intimidate what I say. Its not a box of thickk thickk cream rising to the tip but skimmed divert rising of the "no fat" kind. The book doesnt merit the attention. Its ghastly. In the meantime, there are lots of books that will not be reviewed, she said.

Shrivers Orange Prize-winning novel has left on to sell over 600,000 copies in Britain given announcement and is now being blending as a movie starring Tilda Swinton.

The book dramatises a Columbine-style high-school electrocute committed by a derelict son who kills his classmates and clergyman with a crossbow. It is told by a array of letters created by his mother, Eva Khatchadourian, a New York career lady and demure primogenitor whose attribute with her son is stretched when she does not experience a pour out of umbrella love for him after his birth.

Reflecting behind to the primary success of the book, Shriver said: I had done no income and I was a edition pariah. I had no clout. The book came inside of a hair of not being published. My former representative hated it and referred to I rewrite it as a humerous entertainment or but the propagandize massacre.

Kate Mosse, co-founder of the Orange Prize, whose prior winners embody Zadie Smith and Rose Tremain, pronounced the reason there were a series of unchanging and one-off awards was to await women writers in all stages of their careers.

To revive or not to restore? One would be hard-pressed to gawk on the fanciful easy Tintoretto at Kingston Lacy and interpretation that it would have been improved left as the grubby board that William Bankes brought to Britain 160 years ago.

But the actuality is that not all inventive replacement jobs are so unambiguously beneficial. When Leonardo Da Vincis Last Supper in Milan was easy there were a little areas of the fresco that were over repair. The restorers motionless to re-paint these tools in resigned watercolours to prove they were not strange work. The outcome was not what Leonardo intended.

And if replacement is desirable, because stop at paintings? Why not reconstruct the Parthenon? Or the Colloseum? The answer is that we see nobleness and pathos in hull and we recognize that a buildings infirmity tells us something about the history. But is there not nobleness and pathos in a used old master too? And doesnt a paintings repairs additionally discuss it us something critical about the history? After all, Vasari spoken the Last Supper already "ruined" when he was essay his Lives. And that was in the 1550s. We benefit something when we restore. But we need to be aware of what we infrequently lose too.
