Daylilies from Canada…

Date of Issue : March 1, 2012

Two brilliant, colourful and exquisite daylilies (Hemerocallis) grace the seventh issue in Canada Post’s beloved flower series.

Daylilies

The Daylily (Hemerocallis) was long placed in the Lily family (Liliaceae), but is now considered to belong in the plant family Hemerocallidaceae. This term, from the Greek words meaning “beauty” and “day,” alludes to the fact that each flower lasts for just one day. Since there are many flower buds on each flower stalk and many stalks in each cluster, the overall flowering period is usually several weeks long. The flowers of most species open at sunrise and wither atsunset, often replaced by another on the same stalk the next day. Although not commonly used for arrangements, daylilies make good cut flowers, as new blossoms continue to open over several days.

Originally, daylilies could be found only in yellow, orange, and reddish-brown. Today, colours range from near-white, to yellow, orange, pink, red, purple, blue and more. While the roadside yellow or orange daylilies—known to hybridizers as Hemerocallis fulva (or Hemerocallis fulva Europa)—are forms of the cultivated types that ‘escaped’ and now grow wild, all modern daylilies have evolved through a complicated history of hybridization.

Search continues for secret stamp honoring John Glenn's historic spaceflight 

 

image

The 1962 4-cent "Project Mercury" stamp marked the first time that the U.S. issued a previously unannounced commemorative stamp at the same time as the event it was issued to honor: John Glenn’s historic Friendship 7 spaceflight.

 

4-cent 'Project Mercury' postage stamp sold in 1962 was a surprise

2/20/2012 10:43:38 AM ET

Fifty years ago today (Feb. 20), John Glenn, the first American to orbit the Earth, relied on ground stations located across the planet to communicate with his control team. But after his Mercury spacecraft, Friendship 7, safely splashed down, it was another type of station that took over tracking his historic mission: U.S. post offices.

For the first and only time in the country's postal history, the United States Post Office Department — since 1971, the U.S. Postal Service — surprised the public with the release of a secret stamp celebrating Glenn's successful mission. The 4-cent "Project Mercury" postage stamp was revealed and immediately put on sale in 305 post offices within an hour of Glenn's triumphant return to Earth at 2:43 p.m. EST (1943 GMT) on Feb. 20, 1962.

Half a century later, collectors are still searching for those first-day-of-issue stamps.

"The U.S. Post Office Department signaled the first orbital flight of a United States astronaut today with the issuance of a commemorative stamp, placed on sale throughout the country on the exact hour Astronaut John Glenn's historic flight was officially completed," the department stated. "It is the first time in history that a previously unannounced commemorative stamp was issued simultaneously with the event it memorializes."

As news of the stamp spread over radio and television, the public began lining up at their closest post offices that had stock of the now no longer secret issue. Collectors in particular drove many miles to have their blank envelopes postmarked with the surprise stamp, creating a collectible for that first day's release and the historic space flight it honored.

Without a way to coordinate nationwide, collectors couldn't know however if such "first day covers" existed for all 305 stations. To this day, 50 years later, as many as 20 cities are still missing examples.  Read More…

Fraunhofer lines : The Rainbow lines

 

225th Birthday Joseph von Fraunhofer

Dater of Issue : 2 January 2012

Fraunhofer lines

Solar spectrum with Fraunhofer lines as it appears visually.

In physics (optics) , the Fraunhofer lines are a set of spectral lines named after the German physicist Joseph von Fraunhofer (1787–1826). The lines were originally observed as dark features (absorption lines) in the optical spectrum of the Sun.

The Fraunhofer lines are typical spectral absorption lines. These dark lines are produced whenever a cold gas is between a broad spectrum photon source and the detector. In this case a decrease in the intensity of light in the frequency of the incident photon is seen as the photons are absorbed, then re-emitted in random directions, which are mostly in directions different from the original one. This results in an absorption line, since the narrow frequency band of light initially traveling toward the detector, has been effectively scattered in other directions. Absorption lines are produced even during reflection from an illuminated cold gas, since after reflection there is still the opportunity for a selective absorption (and re-scatter) between the point of reflection and the detector. By contrast, if the detector sees photons emitted directly from a glowing gas, then the detector often sees photons emitted in a narrow frequency range by quantum emission processes in atoms in the hot gas, resulting in an emission line. In the Sun, Fraunhofer lines are seen from gas in the outer regions of the Sun, which are too cold to directly produce emission lines of the elements they represent.

Philatelic Tributes to the great scientist, Madam  Curie !! More news for coin collectors……This is all for  today… Have a nice time !!

Space Post Office

In this era of Facebook, email, Twitter and other social media, getting a postcard from someone's travels has a certain appeal.China's mail service looks to be taking that tourist postcard to a whole new level.


To celebrate  docking of the
Shenzhou-8 unmanned spacecraft with space lab module Tiangong-1, China's post authority has opened a new branch office outside the country and out of this world -- 343 kilometers above the Earth, to be exact.

Opening for business on the same day, the China Post Space Office has two venues -- one on-the-ground base inside the Beijing Aerospace Command and Control Center (BACCC) and one "virtual office" aboard the Shenzhou-8 spacecraft. There is also a new designated post code -- 901001.

China Post Group’s general manager Li Guohua told China Daily the post office will be able to deliver mail from the public to astronauts in future. The office will also issue postal souvenirs, such as stamps and envelopes that depict China's major space program events.

Chukha Hydel Project

Bhutan 1988

Indian President Shri. R. Venkatraman inaugurated this project in October 1988

Cementing A Friendship

The inauguration of Chukha was notable in other respects as well. Its sheer size and logistical complexity dwarfed all other public works projects in Bhutan combined.

untitled

It was also a milestone in the regional co-operation, with an amicable deal worked out to share the renewable hydropower resource for the benefit of both countries.At the inauguration, President Venkataraman said the Project symbolized the firm friendship between India and Bhutan. With Chukha, the Bhutanese economy took a leap forward.

chukha

The 336MW Chukha hydel project, which harnesses the waters of the Wong Chhu or Raidak River, was historically one of the largest single investments undertaken in Bhutan, and it represented a major step toward exploiting the country's huge hydroelectric potential. It was built by India on a turnkey basis, with India providing 60% of the capital in a grant and 40% in a loan at highly concessional terms and conditions. In the arrangement, India receives in turn all the electricity generated from the project in excess of Bhutan’s demand at much cheaper prices than India’s generation cost from alternative sources. Located between Thimphu and the Indian border, a 40 metres (130 ft) diversion dam was built at Chimakoti village, 1.6 kilometres (0.99 mi) upstream of the confluence of the Ti Chhu and Wong Chhu rivers. From the dam water was diverted through 6.5 kilometres (4.0 mi) long tunnels to a fall of more than 300 metres (980 ft) to Chukha power house for generation of electricity. Construction started in 1974 and completed in 1986-88.

The construction of Bhutan’s first mega power project, the 336 MW Chhukha hydro-electric project on Wangchu river began in the 70s. The Nu. 2,460 million turnkey power plant was funded by the Government of India which provided a 60 percent grants and 40 percent loan at 5 percent per annum repayable in 15 years in equated annual installments. The first repayment was to be made 3 years after each withdrawal of the loan.

The project was successfully commissioned in 1986 but the project was handed over to Bhutanese management only in June 1991. The beneficiaries of the hydro plant outside Bhutan are West Bengal, Bihar, Jharkhand, Orissa, Sikkim and Damodar Valley Corporation (DVC) of India. A large portion of the power generated is exported to India. Till Tala hydropower project was commissioned Chhukha was the biggest contributor to Bhutan’s exchequer.
