How power companies make it hard to save with solar

High energy bills are a persistent monthly burden for everyone, but they weigh especially heavily on disadvantaged communities. Between recent utility rate increases and volatile natural gas prices, the financial drain on already challenged household budgets shows no sign of easing.

To lower costs and take control of their own energy consumption, some members of minority and low- to moderate-income communities have turned to solar power. However, the state’s monopoly utilities are leading an attack on this cost-saving energy option by pushing for unfair changes to the state’s solar net metering policies.

Net metering is a billing system that allows homeowners who have installed solar to send any extra power their panels produce back to the energy grid, in exchange for credits that lower their bills. This fair system benefits both homeowners and utilities by letting homeowners cut down on energy costs and utilities resell the excess power for a profit.

Unfortunately, big utilities are bent on furthering their monopolies and expanding their record-breaking profits even more – all at the expense of consumers. They are pushing the Florida Legislature to essentially do away with net metering and the benefits it brings to homeowners.

They also have a history of using front-line communities and people of color to shield their greedy intentions, going so far as claiming that net metering actually increases these groups’ utility rates.

This simply isn’t the case. Solar homeowners make investments in solar themselves and provide power that adds a net benefit to the energy grid. This reduces costs for everyone, and that’s especially important for disadvantaged customers suffering under skyrocketing energy costs.

Power companies have a history of profiting off low-income and minority communities. They recently pushed for rate increases that will add up to billions of dollars over the next few years, and customers will be socked with the bill. The worst effects will be felt by poor communities, where too many residents already live without consistent access to electricity.

Utilities already left these vulnerable groups in the dark during the COVID-19 pandemic. They shut the lights and air conditioning off on over 500,000 Floridians at the height of the public health and economic crisis. While too many of our neighbors struggled to pay their utility bills, they brought in record earnings in 2020.

Power companies’ attack on home-based solar energy demonstrates their continued insistence that their customers rely on outdated, dangerous sources of energy that put Florida closer to the devastating consequences of climate change. That poses an even greater threat to minorities and disadvantaged communities, as they will experience the first and worst damage from the warming climate.

For the sake of these vulnerable communities, Florida must ensure that important clean energy policies are preserved and advanced. The Legislature should stop this unfair, unwanted attack on net metering and the Florida communities who benefit from it.

PG&E may slash credits to homes with excess solar power. Where do MID and TID stand?


John Holland, Dale Kasler
Thu, December 23, 2021

Pacific Gas & Electric Co. seeks to cut by about half its payments for surplus power from solar panels on homes.

The proposal would affect Stanislaus County residents who don’t get electricity from the Modesto or Turlock irrigation districts. It would apply in most of San Joaquin and Merced counties and all of Tuolumne and its mountain neighbors.

The solar industry blasted the plan, released Dec. 13 by the California Public Utilities Commission. Critics say it would hamper the state’s effort to reduce the emissions behind climate change.

The appointed commission plans to vote on the staff proposal Jan. 27. It would apply to the three major investor-owned utilities in California: PG&E, Southern California Edison and San Diego Gas & Electric.

These companies argue that the solar industry has matured enough to allow much smaller credits each month for surplus power. They also say nonsolar customers pay more because of the breaks for the panel owners.

The solar defenders include Alex Williams, a founding partner with Solar Energy Partners, a Turlock-based company that helps homeowners arrange for panels.

“By shifting the economics so drastically in the direction of the utility, it essentially eliminates the benefit the customers currently receive from choosing to go solar,” Williams said in an email to The Modesto Bee. “If California is going to reach the (climate) goals and targets set forth in SB 100, then we have to do it together and there has to be a sharing of benefits between all stakeholders.”

The changes would not apply to the 200,000-plus customers served by MID and TID, because they are not under PUC oversight. Their elected boards set their own policies for crediting surplus solar power.

MID pays 7.6 cents per kilowatt-hour for output that exceeds a solar customer’s own needs, Public Affairs Specialist Samantha Wookey said by email. The district serves part of Stanislaus County and a few areas in San Joaquin.

TID’s rate averages about 5 cents per kilowatt-hour, Communications Division Manager Constance Anderson said by email. The figure varies monthly with the overall power market.

PUC plan would affect 1.3 million

The PUC staff released the plan for investor-owned utilities after more than a year of study. It would affect about 1.3 million rooftop solar customers.

The staff said the current system generates an overly generous subsidy, worth a combined $3 billion a year, that helps mostly upper-income homeowners.

By contrast, the commission said the new pricing system will help California’s power grid cope with its most pressing need: the summertime demand for electricity after the sun goes down and solar generation fades. California endured two nights of rolling blackouts in August 2020 and narrowly avoided blackouts during a July heat wave.

Martha Guzman Aceves, the PUC commissioner who’s tracking the issue most closely, said the staff’s plan includes rebates for existing solar customers to purchase battery-storage units, which can cost several thousand dollars.

Aceves said the state wants the solar industry to keep growing but “it needs to evolve to what the grid really needs, and that involves storage.” The rebates would come to $3,200 apiece under the commission’s plan.

Subsidies have helped solar spread

The plan likely would scramble the economics of solar energy, which accounts for 25% of the state’s energy use in daytime. Rooftop solar costs about $20,000 to install, and the subsidized rate has helped popularize the technology.

PG&E’s solar customers, for example, currently get an average of more than 20 cents for every kilowatt-hour they don’t use and deliver to the grid. The new rate would be based on a complicated “time of use” system and would amount to 10 cents or less for many PG&E customers, Aceves said.

The state’s largest utility, PG&E called the proposal “a step in the right direction to modernize California’s outdated rooftop solar program.”

Advocates for solar energy said reducing the credits would slow the adoption of a renewable energy source that has become a key element in California’s battle against climate change.

“The only winners today are the utilities, which will make more profits at the expense of their ratepayers,” said Abigail Ross Hopper, president and CEO of the Solar Energy Industries Association, in a prepared statement. “We urge Gov. Newsom to act quickly to change this decision — at risk are 65,000 solar jobs, the security of our electricity grid, and the health of California residents and our planet.”
Homes face a monthly grid charge

Not only would the subsidy fall, but solar customers would pay considerably more during those hours when they’re drawing electricity from the grid. They also would have to begin paying the utilities a “grid participation charge” to connect to the power grid.

The grid charge would phase in over four years, to an average of $40 a month for the average solar customer. Aceves said the fee is needed to help pay for programs for low-income customers.

The big utilities, as well as some consumer advocacy groups, have been pushing the state for more than a year to reduce the credit they pay solar customers for excess power. PG&E says its fee of more than 20 cents is considerably more than the true cost of solar.

PG&E officials say the subsidy gets lumped onto the backs of nonsolar customers, who tend to have lower incomes, to the tune of $170 a year in higher bills.

Solar advocates, however, say the rooftop panels aren’t limited to the wealthy. A study by the Lawrence Berkeley National Laboratory said “solar adoption skews toward high-income households,” but added that 42% of installations in California in 2019 were at households with less than $100,000 in annual income.

“Solar right now is increasingly affordable for low- and moderate-income families,” said Bernadette Del Chiarro, head of the California Solar and Storage Association.” The commission’s plan “is going to put it out of reach for working and middle-class families.”

And she said the “grid participation charge,” which would total $480 a year for most customers, would further damage the attractiveness of solar. “It’s going to be pretty hard to make a solar system pay for itself,” she said.
$600 million for lower-income people

The commission’s plan includes the creation of a $600 million “equity fund” to help disadvantaged families. But Del Chiarro said that won’t be nearly big enough.

The plan wouldn’t change solar economics overnight. Customers without solar would have another four months to install rooftop panels and qualify for the current rates, and existing customers would have a “glide path” of several years to transition to the system.

The California Legislature mandated the subsidies in 1995, when solar was in its infancy. Even as the industry has grown, attempts to tweak the credits have aroused controversy.

US became 'arrogant' after fall of Soviet Union: Gorbachev


Gorbachev resigned as president of the Soviet Union on December 25, 1991, days after the leaders of Belarus, Russia and Ukraine said the USSR no longer existed (AFP/VITALY ARMAND)


Fri, December 24, 2021, 

The United States grew "arrogant and self-confident" after the collapse of the Soviet Union, leading to the expansion of the NATO military alliance, former leader Mikhail Gorbachev said on Friday.

In recent years President Vladimir Putin has grown increasingly insistent that NATO is encroaching close to Russia's borders, and Moscow last week demanded "legal guarantees" that the US-led alliance halt its eastward expansion.

Gorbachev resigned as president of the Soviet Union on December 25, 1991, days after the leaders of Belarus, Russia and Ukraine said the USSR no longer existed.

"How can one count on equal relations with the United States and the West in such a position," Gorbachev told state news agency RIA Novosti on the eve of the anniversary of his resignation as the leader of the USSR.

He said there was a "triumphant mood in the West, especially in the United States" after the fall of the Soviet Union in 1991.

"They grew arrogant and self-confident. They declared victory in the Cold War," said the 90-year-old.

He insisted Moscow and Washington were "together" in pulling the world out of confrontation and the nuclear race.

"No, the 'winners' decided to build a new empire. Hence the idea of NATO expansion," Gorbachev added.

However, he welcomed forthcoming security talks between Moscow and Washington.

"I hope there will be a result," he said.

Last week Moscow presented the West with sweeping security demands, saying NATO must not admit new members and seeking to bar the US from establishing new bases in former Soviet countries.

Putin said Thursday that Washington had been willing to discuss the proposals and talks could happen at the start of next year in Geneva.

A senior US official said Washington was ready for talks "as soon as early January".

Putin, a former KGB agent and loyal servant of the Soviet Union, was dismayed when it fell apart, once calling the collapse "the greatest geopolitical disaster of the 20th century".

Many Russians remember the end of the Soviet era for the economic and political crisis that followed and credit Putin with returning the country to the international arena.

Valentina Shmeleva labelled the leaders immediately preceding Putin as "traitors", particularly Russia's first president Boris Yeltsin.

"Gorbachev destroyed the Soviet Union and the drunkard Yeltsin helped," said the 84-year-old.

Evgeny Dotsenko, 46, said it was a "pity" that the USSR fell apart.

"I was born and grew up in the Soviet Union and I liked living then. Everything was free: education, medicine, everything," Dotsenko, who works as a metro electrician, told AFP.

Putin Loses His Cool When Confronted Over Ukraine, Claims It Belongs to Lenin Anyway

Allison Quinn
Thu, December 23, 2021

Reuters

Vladimir Putin’s normally predictable annual press conference briefly veered off the rails Thursday when the Russian president appeared to lose his cool after being questioned about Moscow’s aggression in Ukraine.

When a reporter for Sky News asked whether Moscow could give security guarantees and promise not to invade its neighbor, Putin exploded: “You are demanding guarantees from us? It’s you who should give us guarantees. Immediately. Right now. And not talk it over for decades.”

His comments came as Ukraine released satellite images it said showed more Russian forces building up at its border, and the Russian Defense Ministry announced massive “attack” drills in Crimea.


Moscow has repeatedly claimed the moves are in response to what it sees as the threat of an expanding NATO, while Western officials view the Kremlin’s saber-rattling as a form of coercive diplomacy through which it hopes to keep its grip on Ukraine.

Putin repeatedly portrayed Russia as the victim at his press conference, claiming Moscow had been dragged into the Ukraine conflict when it is really just a “mediator.”

“They want to make us a party to the conflict, and it’s not like that,” he said. (Apparently in his view it was not the Russian forces seizing Crimea in 2014, the years of Kremlin propaganda, Russian support for separatists, and the reported weapons supplies that made Russia a party to the conflict.)

He accused NATO of being the true aggressor, appearing to briefly seethe as he suggested the West has always sought to destroy Russia.

“They tricked us. Just cheated us. Five waves of NATO enlargement,” he said.

“And on top of that—no matter what we did, you always expressed ‘concerns.’ Get out of here with your ‘concerns.’ We will do what we consider necessary. We want to ensure our safety,” he said.

Later in the conference, Putin said there was an overall “positive response” from the U.S. to the Kremlin’s “red line” proposals on NATO.

“Our American partners say they’re ready to start discussions early next year in Geneva. Both sides have named representatives and I hope that things will continue along the same path,” he said.

“Our actions will depend on the situation in the sphere of security. We made clear that the further expansion of NATO in the East is not acceptable. We’re not the ones who came to the States with missiles. They’re the ones setting up missiles right on our doorstep,” he said.

“And what if we set up missiles on the border of the U.S. and Canada? Or Mexico?”

Visibly angry, he went on to vent frustration over the idea of a sovereign Ukraine, suggesting the country actually belongs to Vladimir Lenin.

“And who did California belong to?” he asked, apparently referring to California being part of Mexico prior to the Mexican-American War.

“And Texas? Did they forget that or something? Well okay, everyone has forgotten, and they don’t remember the way they now remember about Crimea. We also don’t remember who created Ukraine–Lenin Vladimir Ilyich, when he created the Soviet Union.”

Moscow court fines Google nearly $100 million for failing to delete 'illegal' content
Fri, 24 December 2021


A Moscow court slapped Google with an unprecedented hefty fine of nearly $100 million on Friday as Russia ramps up its pressure on foreign tech giants.

Moscow has piled fines on the world's biggest internet platforms, accusing them of not moderating their content properly and interfering in the country's affairs.

But so far fines on Facebook parent company Meta, Twitter, and Google have stretched into the tens of millions of rubles, not billions.

However on Friday a Moscow court fined Google a record 7.2 billion rubles, ($98 million, 86 million euros), the court's press service said on Telegram, for repeatedly failing to delete illegal content.

The content was not specified, but Russia regularly takes legal action for not removing content it labels illegal, such as pornographic material or posts condoning drugs and suicide.

"We'll study the court documents and then decide on next steps," Google's press service told AFP.

Interfax news agency said that the massive fine was calculated as a percentage of Google's annual earnings and was the maximum penalty for a repeated violation.

Meta -- which has a hearing in court later today on the same charges -- has also been threatened with a revenue-based fine.

On Thursday, Twitter was handed its latest fine of three million rubles ($40,000) after authorities started throttling its services in the spring.

In the past few years, the Russian government has used the pretext of protecting minors and fighting extremism to control the Russian segment of the web and began developing a so-called sovereign internet.
Fines and threats

Ahead of parliamentary elections in September, Russia's media watchdog blocked dozes of websites linked to jailed Kremlin critic Alexei Navalny, whose organisations have been banned in Russia as "extremist".

The regulator also ordered Google and Apple to remove an app dedicated to Navalny's "Smart Voting" campaign which advised supporters who to vote for to unseat Kremlin-aligned politicians.

The Silicon Valley giants complied, with sources telling AFP the decisions came after authorities threatened to arrest local staff.

Russia's media regulator has also blocked dozens of websites linked to Navalny.

Earlier, during protests in January in support of Navalny, authorities accused platforms including Google's YouTube and Twitter of meddling in Russia's domestic affairs by not deleting posts calling for people to join the rallies.

President Vladimir Putin that same month complained that large technology companies were competing with states.

Russia has already blocked a number of websites that have refused to cooperate with authorities, such as the video platform Dailymotion and LinkedIn.

As part of broad efforts to bend foreign tech under its control, Russia in September banned six major VPN providers including Nord VPN and Express VPN.

Russia also introduced a new law demanding that smartphones, computers and other gadgets sold in the country come with pre-installed domestic software and apps.

Russia's opposition accuses the Kremlin of using such regulations to further stifle freedom of speech and clamp down on online dissent.

Argentina battling Patagonian forest fires

Fri, December 24, 2021

Some 250 firefighters and national park employees battled blazes Friday in Argentina's Patagonia region which have destroyed thousands of hectares of forest, authorities said.

Fires are raging in high-altitude, little populated forest areas of the southern provinces of Rio Negro, Chubut and Neuquen.

Some are as much as 300 kilometers (200 miles) apart. No casualties have been reported, and no evacuations ordered.

Argentina's environment ministry said the firefighting effort was complicated by difficult terrain, distances between blazes, wind, high temperatures and dry vegetation in the midst of a drought.

Fires in the Patagonian summer are a common occurrence.

Last year, tens of thousands of hectares of forest were destroyed in fires in Argentina.
Senegal railway opening overshadowed by compensation protest

Fri, December 24, 2021,

After five years' work and at a cost of more than a billion dollars, Senegal's capital city next Monday will finally welcome a new commuter railway line.

Politicians are lining up to extol the benefits of slashing journey times and decongesting Dakar once the gleaming TER regional express trains start to roll.

But thousands of residents claim they have not been properly compensated for homes and businesses that were demolished to make way for the much-trumpeted line.


"We plan to block the start of the TER on the day of the inauguration to demand satisfaction for our grievances," said Ibrahima Cisse, who leads a group of some 16,000 people who say they are owed money.

Many are also furious that the rehousing they were promised has not yet been completed.

The government says that almost everyone who is owed compensation has received it, but accepts that some resettlements have not yet happened.

- 'Record-breaking' works -

Travelling at up 160 kilometres (100 miles) per hour, the trains will ply the 36-kilometre (22-mile) route between Dakar and the new city of Diamniadio in about 20 minutes.

Supporters of the project say it will carry 115,000 people per day, saving them hours otherwise spent in the capital's monstrous traffic jams.

The time it took to build "may seem long, but we have broken records for the speed of construction, and despite Covid," Stephane Volant of Seter, the railway's operating company, told AFP.

Critics say the true cost of the project is more than a thousand trillion CFA francs ($1.7 billion 1.5 billion euros), compared with its budget of 780 billion francs.

Seter will use 15 four-car dual-mode trains with diesel and electric power, built by Alstom, one of several French companies, including Seter, that have had a leading role in the project.

Tickets for the Dakar-Diamniadio stretch will cost 1,500 CFA francs ($2.5) in second class, and 2,500 francs ($4.3) in first.

The railway line, which is owned by the Senegalese state, is a centre piece of President Macky Sall's plan to overhaul the nation's infrastructure by 2035.

Improving the situation in Dakar is one of Sall's pet themes.

The city's five million inhabitants make up almost one-third of Senegal's population and account for nearly all of the country's economic activity.

Traffic jams cost the city the equivalent of $172 million per year, according to official figures.

The TER stations will hook up with express buses which will operate on reserved lanes on a toll highway that has been operating for the last decade.

In the project's second phase, the line will be extended another 19 kms to the Blaise Diagne International Airport, which opened in 2017. Travel time to downtown Dakar from the airport would take less than 50 minutes.

- 'Living dead' -

Behind these impressive figures, those battling for compensation say their lives have been wrecked by the train line.

"The TER has impoverished us. It's a project that has created the living dead," said Amina Bayo, a member of Cisse's campaign group, called the Collective of People Affected by the TER.

Some 2,000 individuals and businesses have filed complaints with Apix, the state-owned agency that has overseen the project, claiming 50 billion CFA francs ($86 million/76 million euros).

They say that in many cases, assessors badly under-valued their property.

But Yatma Dieye of Apix told AFP that "98.8 percent of people affected by the project have been compensated."

"Payments began in February 2017. Everything was transparent and done according to international standards," he said.

But he conceded that the state was "still working" on resettlement, a point that can be seen clearly in one Dakar suburb intended to house the evicted.

Unfinished market stalls with electric wires hanging down to the ground sit in a stretch of weeds near a disused lot close to a motorway.

"The construction site was supposed to be completed in April 2018 for more than 2,000 evicted traders," said one of them, Ngagne Amar.

Many compensation claimants face an uphill battle, especially those lacking documentation.

Dieye said much of the evidence received by Apix "was generally weak."

Flying squirrels found living on University of Nebraska campus

Dec. 23 (UPI) -- A crew working to cut down a dying oak tree on the University of Nebraska's East Campus made an unexpected discovery in a hollow limb -- a family of flying squirrels.

Brian Dieterman, assistant manager for the university's landscape services, said his crew was baffled when a creature poked its head out from a hole in a hollow limb of the tree.

"We're used to seeing squirrels in trees, but this didn't look like a squirrel," Dieterman told the Lincoln Journal Star.

Dieterman said the workers figured out what animals they were dealing with when they started gliding to a nearby tree.

The university shared a video to Facebook showing the flying squirrels in flight.

Larkin Powell, a professor of conservation biology at the school, said Nebraska's last-known population of flying squirrels is about 90 miles away in the area around Indian Cave State Park.

Powell said it's hard to say how long the gliding mammals have been on campus, as they are nocturnal and notoriously elusive.

"It's among the species that's harder to document because they're not out when people are around," he said. "And they're little dudes."

Powell said there haven't been any reported sightings between the animals' natural habitat and Lincoln, and it would have been difficult for them to make the journey on their own. He said they may have hitched a ride on a truck or with someone's camping supplies.

"As a biologist, I've seen crazy things that animals can do. But it's very unlikely they made it here on their own," he said.


 

Postcards from Yosemite and beyond: Winter snowfall blankets the Sierra

After nearly two years of focusing on COVID-19 and working inside 13 different hospitals for the Los Angeles Times, it was finally time to go outside, away from crowds, and take a break from the pandemic.

First stop: the General Grant Tree in snow — sometimes called the nation's Christmas tree — located in Grant Grove in Kings Canyon National Park.

I was attempting to make my way to General Sherman and other sequoias affected by the KNP Complex fire, but the road between Sequoia National Park and Kings Canyon National Park remains closed due to inclement weather.

General Grant did not disappoint. The tree is about 268 feet high, and the circumference of the trunk is 107 feet, second in size only to General Sherman.

The crowd was minimal and the path slow due to ice, allowing me to focus both on the details of the icicles dripping from moss and the giant Sequoia in the snow.

Yosemite took my breath away. My first visit. Ancient giant granite cliffs. Snow-covered meadows. Ice weighing down the pine needles. The rush of the waterfalls breaking the silent air. I am already planning my second visit.

And lastly, a brief stop to photograph trees affected by the Caldor fire near Martin Meadows, about 35 miles south of Lake Tahoe. The Caldor fire burned 221,835 acres in the fall of 2021. Recent storms have dropped multiple feet of snow, with more on the way.

My spirit feels rejuvenated having a few days void of focusing on COVID-19.

During winter’s solstice, I took the long drive home through fog on icy roads. It gave me time to reflect on the impermanence of life, the inevitability of death and the continuum of hope during my brief excursion from the city.

General Grant is about 3,000 years old. El Capitan in Yosemite Valley was formed roughly 200 million years ago. And one day children will again play in the forests scarred by fire. We will get past the pandemic in time. And I felt at peace having spent time in nature.

Don't ask astronomers to choose between the Hubble Space Telescope and the new kid on the cosmic block, the James Webb Space Telescope.

"Comparing Hubble and Webb is like asking if you will love your second child as much as your first," said Susan Mullally, Webb's deputy project scientist at the Space Telescope Science Institute in Baltimore.

"Hubble will always be loved for its awe-inspiring images of our universe and will continue to collect important data for astronomers. Webb gives us new and unique eyes of places that we have never been able to reach."

With NASA and the European Space Agency's Hubble pushing 32 years in orbit, the bigger, 100 times more powerful Webb is widely viewed as its successor even though the two are vastly different. Its liftoff is slated for Saturday morning from the coast of South America.

The lowdown on Hubble versus Webb:

ROCKET RIDES

Hubble caught a lift to orbit tucked inside NASA's space shuttle Discovery in 1990. It quickly ran into trouble: one of the telescope's solar wings jammed as it was unfurling. Astronauts suited up for an emergency spacewalk, but commands from Earth freed the panel. Within weeks, Hubble's blurry vision was detected. Spacewalking astronauts fixed it three years later. Soaring from South America on a European Ariane rocket, Webb won't be reachable by astronauts at its destination 1 million miles (1.6 million kilometers) away. Bigger and more intricate than Hubble, Webb will be a goner if its foldout mirror and sunshield snarl.

LET THERE BE LIGHT

Webb is expected to behold light from the universe's  and galaxies, beyond Hubble's range. This light will reveal how the original stars looked 13.7 billion years ago. Hubble has stared as far back as 13.4 billion years, disclosing a clumpy runt of a galaxy that is currently the oldest and farthest object ever observed. Astronomers are eager to close the 300 million year gap with Webb and draw ever closer in time to the Big Bang, the moment the universe formed 13.8 billion years ago. "It's like looking at the picture book of my kids and missing the first two years, right? Trying to figure out where they come from," said NASA science chief Thomas Zurbuchen.

Hubble sees what we see—with a little ultraviolet and infrared thrown in. Webb has infrared vision, allowing it to pierce cosmic clouds of dust. The shorter visible and ultraviolet wavelengths emitted by the first stars and galaxies have been stretched as the universe expands, so Webb will see them in their elongated, heat-emitting infrared form. That's why Webb's detectors need to run at minus 400 degrees Fahrenheit (minus 240 degrees Celsius). To stay chilled, Webb carries a parasol the size of a tennis court. Between each of the sunshield's five layers is a gap so heat can escape out the sides. Multiple layers also better protect against micrometeorite hits.

SIZE MATTERS

To discern the universe's first, faint stars, Webb requires the largest mirror ever launched for astronomy. The mirror spans more than 21 feet (6.5 meters), yet is lighter than Hubble's, which is 8 feet (2.4 meters) across. That's because Webb's mirror is made of beryllium, a strong but lightweight metal. It's also segmented, allowing it to fold like a drop-leaf table for launch. Each of the 18 hexagonal segments are the size of a coffee table and coated with ultra-thin gold, an ideal reflector of infrared light.

LOCATION, LOCATION, LOCATION

Hubble circles 330 miles (530 kilometers) overhead. The altitude was dictated by the capabilities of NASA's space shuttles, which delivered Hubble to orbit and then made five service calls. Webb is bound for more a more distant spot—1 million miles (1.6 million kilometers) away at what's called the second Lagrange point. This is where the gravitational forces of the Earth and sun balance, requiring minimal fuel for a spacecraft to stay put. Webb will constantly face the nightside of Earth as the spacecraft and planet swoop around the sun in unison.

GROWING PAINS

Hubble was years late and millions over budget by the time it rocketed into orbit in 1990. Webb also is years late with huge cost overruns. NASA's tab for Hubble from its 1970s development until now: $16 billion, adjusted for inflation. That doesn't include all the shuttle flights for launch and repairs. Webb's price tag is an estimated $10 billion; that includes the first five years of operation. The European Space Agency is picking up the launch costs, with a French-built Ariane rocket providing Webb's lift from French Guiana.

HUBBLE AND WEBB NAMESAKES:

Astronomer Edwin Hubble confirmed a century ago that countless galaxies exist beyond our Milky Way and the universe is constantly expanding. James Webb led NASA from 1961 to 1968, presiding over Projects Mercury and Gemini, and the early phase of Apollo's moon-landing program. In 2002, a decade after Webb's death, NASA chose his name for the new telescope. But now some scientists and others want a new name, given Webb's State Department and NASA leadership during the Truman administration, when government workers were fired for being gay. NASA's historian conducted an archival search of Webb this year, but found no evidence warranting a name change, said Administrator Bill Nelson
