海外TECH	Engadget	NASA's John Mather keeps redefining our understanding of the cosmos	https://www.engadget.com/inside-the-star-factory-chris-gunn-christopher-wanjek-mit-press-143046496.html?src=rss	Space isn t hard only on account of the rocket science The task of taking a NASA mission from development and funding through construction and launch ーall before we even use the thing for science ーcan span decades Entire careers have been spent putting a single satellite into space Nobel winning NASA physicist John Mather mind you has already helped send up two In their new book Inside the Star Factory The Creation of the James Webb Space Telescope NASA s Largest and Most Powerful Space Observatory author Christopher Wanjek and photographer Chris Gunn take readers on a behind the scenes tour of the James Webb Space Telescope s own journey from inception to orbit Weaving examinations of the radical imaging technology that enables us to peer deeper into the early universe than ever before with profiles of the researchers advisors managers engineers and technicians that made it possible through three decades of effort In this week s Hitting the Books excerpt a look at JWST project scientist John Mather and his own improbable journey from rural New Jersey to NASA nbsp MIT PressExcerpted from Inside the Star Factory The Creation of the James Webb Space Telescope NASA s Largest and Most Powerful Space Observatory Copyright by Chris Gunn and Christopher Wanjek Used with permission of the publisher MIT Press John Mather Project Scientist nbsp ーThe steady hand in control nbsp John Mather is a patient man His Nobel Prize in Physics was thirty years in the making That award for unswerving evidence of the Big Bang was based on a bus sized machine called COBE ーyet another NASA mission that almost didn t happen Design drama Been there Navigate unforeseen delays Done that For NASA to choose Mather as JWST Project Scientist was pure prescience nbsp Like Webb COBE ーthe Cosmic Background Explorer ーwas to be a time machine to reveal a snapshot of the early universe The target era was just years after the Big Bang when the universe was still a fog of elementary particles with no discernable structure This is called the epoch of recombination when the hot universe cooled to a point to allow protons to bind with electrons to form the very first atoms mostly hydrogen with a sprinkling of helium and lithium As the atoms formed the fog lifted and the universe became clear Light broke through That ancient light from the Big Bang itself is with us today as remnant microwave radiation called the cosmic microwave background nbsp Tall but never imposing demanding but never mean Mather is a study in contrasts His childhood was spent just a mile from the Appalachian Trail in rural Sussex County New Jersey where his friends were consumed by earthly matters such as farm chores Yet Mather whose father was a specialist in animal husbandry and statistics was more intrigued by science and math At age six he grasped the concept of infinity when he filled up a page in his notebook with a very large number and realized he could go on forever He loaded himself up with books from a mobile library that visited the farms every couple of weeks His dad worked for Rutgers University Agriculture Experiment Station and had a laboratory on the farm with radioisotope equipment for studying metabolism and liquid nitrogen tanks with frozen bull semen His dad also was one of the earliest users of computers in the area circa maintaining milk production records of cows on punched IBM cards His mother an elementary school teacher was quite learned as well and fostered young John s interest in science A chance for some warm year round weather ultimately brought Mather in to University of California Berkeley for graduate studies in physics He would fall in with a crowd intrigued by the newly detected cosmic microwave background discovered by accident in by radio astronomers Arno Penzias and Robert Wilson His thesis advisor devised a balloon experiment to measure the spectrum or color of this radiation to see if it really came from the Big Bang It does The next obvious thing was to make a map of this light to see as theory suggested whether the temperature varied ever so slightly across the sky And years later that s just what he and his COBE team found anisotropy an unequal distribution of energy These micro degree temperature fluctuations imply matter density fluctuations sufficient to stop the expansion at least locally Through the influence of gravity matter would pool into cosmic lakes to form stars and galaxies hundreds of millions of years later In essence Mather and his team captured a sonogram of the infant universe nbsp Yet the COBE mission like Webb was plagued with setbacks Mather and the team proposed the mission concept for a second time in NASA accepted the proposal but that year declared that this satellite and most others from then on would be delivered to orbit by the Space Shuttle which itself was still in development History would reveal the foolishness of such a plan Mather understood immediately This wedded the design of COBE to the cargo bay of the unbuilt Shuttle Engineers would need to meet precise mass and volume requirements of a vessel not yet flown More troublesome COBE required a polar orbit difficult for the Space Shuttle to deliver The COBE team was next saddled with budget cuts and compromises in COBE s design as a result of cost overruns of another pioneering space science mission the Infrared Astronomical Satellite or IRAS Still the tedious work continued of designing instruments sensitive enough to detect variations of temperatures just a few degrees above absolute zero about C From onward Mather was consumed by the creation of COBE all day every day The team needed to cut corners and make risky decisions to stay within budget News came that COBE was to be launched on the Space Shuttle mission STS B in from Vandenberg Air Force Base All systems go Then the Space Shuttle Challenger exploded in killing all seven of its crew NASA grounded Shuttle flights indefinitely COBE now locked to Shuttle specifications couldn t launch on just any other rocket system COBE was too large for a Delta rocket at this point ironically Mather had the Delta in mind in his first sketch in The team looked to Europe for a launch vehicle but this was hardly an option for NASA Instead the project managers led a redesign to shave off hundreds of pounds to slim down to a pound launch mass with fuel which would just make it within the limits of a Delta by a few pounds Oh and McDonnell Douglas had to build a Delta rocket from spare parts having been forced to discontinue the series in favor of the Space Shuttle nbsp The team worked around the clock over the next two years The final design challenge was wait for it a sunshield that now needed to be folded into the rocket and spring released once in orbit a novel approach COBE got the greenlight to launch from Vandenberg Air Force Base in California the originally desired site because it would provide easier access to a polar orbit compared to launching a Shuttle from Florida Launch was set for November COBE was delivered several months before nbsp Then on October the California ground shook hard A magnitude earthquake struck Santa Cruz County causing widespread damage to structures Vandenberg some miles south felt the jolt As pure luck would have it COBE was securely fastened only because two of the engineers minding it secured it that day before going off to get married The instrument suffered no damage and launched successfully on November More drama came with the high winds on launch day Myriad worries followed in the first weeks of operation the cryostat cooled too quickly sunlight reflecting off of Antarctic ice played havoc with the power system trapped electrons and protons in the Van Allen belts disrupted the functioning of the electronics and so on nbsp All the delays all the drama faded into a distant memory for Mather as the results of the COBE experiment came in Data would take four years to compile But the results were mind blowing The first result came weeks after launch when Mather showed the spectrum to the American Astronomical Society and received a standing ovation The Big Bang was safe as a theory Two years later at an April meeting of the American Physical Society the team showed their first map Data matched theory perfectly This was the afterglow of the Big Bang revealing the seeds that would grow into stars and galaxies Physicist Stephen Hawking called it the most important discovery of the century if not of all time nbsp Mather spoke humbly of the discovery at his Nobel acceptance speech in fully crediting his remarkable team and his colleague George Smoot who shared the prize with him that year But he didn t downplay the achievement He noted that he was thrilled with the now broader recognition that our work was as important as people in the professional astronomy world have known for so long nbsp Mather maintains that realism today While concerned about delays threats of cancellation cost overruns and not too subtle animosity in the broader science community over the telescope that ate astronomy he didn t let this consume him or his team There s no point in trying to manage other people s feelings he said Quite a lot of the community opinion is well if it were my nickel I d spend it differently But it isn t their nickel and the reason why we have the nickel in the first place is because NASA takes on incredibly great challenges Congress approved of us taking on great challenges And great challenges aren t free My feeling is that the only reason why we have an astronomy program at NASA for anyone to enjoy ーor complain about ーis that we do astonishingly difficult projects We are pushing to the edge of what is possible nbsp Webb isn t just a little better than the Hubble Space Telescope Mather added it s a hundred times more powerful Yet his biggest worry through mission design was not the advanced astronomy instruments but rather the massive sunshield which needed to unfold All instruments and all the deployment mechanisms had redundancy engineered into them there are two or more ways to make them work if the primary method fails But that s not the only issue with a sunshield It would either work or not work nbsp Now Mather can focus completely on the science to be had He expects surprises he d be surprised if there were no surprises Just about everything in astronomy comes as a surprise he said When you have new equipment you will get a surprise His hunch is that Webb might reveal something weird about the early universe perhaps an abundance of short lived objects never before seen that say something about dark energy the mysterious force that seems to be accelerating the expansion of the universe or the equally mysterious dark matter He also can t wait until Webb turns its cameras to Alpha Centauri the closest star system to Earth What if there s a planet there suitable for life Webb should have the sensitivity to detect molecules in its atmosphere if present nbsp That would be cool Mather said Hints of life from the closest star system Yes cool indeed This article originally appeared on Engadget at	2023-10-22
