The Large Binocular Telescope consists of two 8.4-meter mirrors which function in tandem to provide resolution greater than that of the Hubble Telescope. The LBT’s first “binocular” images were captured recently, marking the end to a long and laborious construction process. We previously discussed the LBT when images were captured from the first mirror to be installed. Quoting: “The LBT … will combine light to produce the image sharpness equivalent to a single 22.8-meter (75-foot) telescope. ‘To have a fully functioning binocular telescope is not only a time for celebration here at LBT, but also for the entire astronomy community,’ UA Steward Observatory Director, Regents’ Professor and LBT Corp. President Peter A. Strittmatter said. ‘The images that this telescope will produce will be like none seen before. The power and clarity of this machine is in a class of its own. It will provide unmatched ability to peer into history, seeing the birth of the universe.’”

PRB_Ohio takes us to Space.com for a story about NASA’s plutonium shortage, and how it may affect future missions to the far reaches of the solar system. The U.S. hasn’t produced plutonium since 1988, instead preferring to purchase it from Russia. We discussed the U.S. government’s plans to resume production in 2005, but those plans ended up being shelved. If NASA is unable to find an additional source, it could limit missions that take spacecraft too far from the Sun. Quoting: “Alan Stern, NASA associate administrator for science, … said he believed the United States had sufficient plutonium-238 on hand or on order to fuel next year’s Mars Science Lab, an outer planets flagship mission targeted for 2017 and a Discovery-class mission slated to fly a couple years earlier to test a more efficient radioisotope power system NASA and the Energy Department have in development. To help ensure there’s enough plutonium-238 for those missions, NASA notified scientists in January that its next New Frontiers solicitation, due out in June, will seek only missions that do not require a nuclear power source.”

CaptainCarrot writes “Phil Plait, aka The Bad Astronomer has summarized for his readers the new results released by NASA from the Wilkinson Microwave Anisotropy Probe (WMAP), which has been surveying the 3K microwave radiation left over from the Massive Bang. Some of the most interesting results: The age of the universe is now known to unprecedented accuracy: 13.73 billion years old, +/- 120 million. Spacetime is flat to within a 2% error margin. And ordinary matter and energy account for only 4.62% of the universe’s total. Plait’s comment on the age result: ‘Some people might say it doesn’t look a day over 6000 years. They’re wrong.’”

Barrista En Flambe alerts us to a stunt that may reflect the desperate funding crisis in British astronomy: astronomers have agreed to beam a 30-second Doritos ad to a solar system 42 light years from Earth. The transmission is being directed at the solar system of 47 Ursae Majoris, a star similar to the Sun which has planets and may have a habitable zone.

Groucho Marx once remarked that whenever things begin to look really dark, remain calm, don’t panic, and above all, turn on a light.

Given the barrage of financial stresses battering the credit and equity markets these days, consumers, economists and investors alike could use some of Groucho’s levity, and some light. In this case the light may appear in the form of the Federal Housing Administration.

What’s old is suddenly new

The Federal Housing Administration, the once-viewed-as-antiquated, irrelevant Great Depression-era government bureau, is suddenly emerging as the centerpiece of government efforts to bolster the U.S. housing market, reported The Wall Street Journal (subscription required.)

The FHA has become the cheapest, and in many cases, the only substitute for borrowers who can make only a small down payment, and the bureau is rapidly gaining market share.

The FHA does not make loans. It provides insurance - - insurance that covers the danger lenders/investors who own the loan assume. Further, the FHA’s insurance is helping to fill the gap created as both Fannie Mae (NYSE: FNM) and Freddie Mac (NYSE: FRE) add fees and increase down payments as compensation for the higher risks mortgage funders state exists in investing in mortgages in today’s financial environment.

FHA: higher mortgage limits

Historically, the FHA has been a means to help lower-income borrowers, but that’s changing, as banks flee many categories of mortgages, Reuters reported. Further, the 2008 economic stimulus bill passed by Congress is also increasing the FHA’s capability to aid the housing market’s recovery.

The economic-stimulus bill passed by Congress and signed by President Bush last month raises the ceiling on the size of loans the FHA can insure to $729,750 in the highest-cost areas, up from a previous cap of $362,790, The Milwaukee Journal reported Friday. The new limits are due to expire at the end of this year, but Congress is likely to renew them, economist Glen Langan, who specializes in Congressional policy, told BloggingStocks Friday.

Further, as a result of the FHA insurance, home buyer interest rates are lower than prevailing market rates. The Journal, citing FHA data, said the interest rate for an FHA-insured $325,000 30-year fixed rate mortgage would be 6% for a borrower with strong credit. The comparable Fannie Mae and Freddie Mac programs would carry a 6.375% interest rate.

Just as important, the FHA program requires a lower down payment: for the above loan, $9,262.50 or 2.85% for the FHA program, $16,250 or 5% for the Fannie Mae and Freddie Mac programs.

Economic Analysis: A ray of light.: Underscoring that the Federal Housing Administration is by no means a cure-all, the FHA can nevertheless become an essential cog in the housing sector recovery process. The FHA’s insurance will result in increased liquidity for the housing sector, and the new, higher loan limits - - up to $729,750 in high-cost areas - - will only speed this liquidity.

Further, unlike the debacle that was many categories of mortgages in the ‘old era’ (no doc loans, said income loans, teaser-rate loans etc.), these FHA insured loans will contain full documentation, feature full amortization, with a fixed interest rate, and with low or modest fees and closing costs, among other lender (and insurer) safeguards. In sum, for good-credit borrowers, the FHA insurance will result in more, low-cost, fixed-rate loans for home buys and mortgage refinancings, at a time when the housing market and the U.S. economy needs it the most. Finally, the U.S. Congress should extend the FHA’s higher $729,500 mortgage ceiling through at least the end of 2009, as one means to keep liquidity flowing into the housing sector, until the sector’s recovery has been statistically confirmed by the U.S. Federal Reserve.
