Image Schématique du Soleil

Schematic Image of the Sun and its Environment

This postcard from my space related collection shows the schematic image of the Sun and its environment. It provides a blue print showing the wide range of phenomena studied by the various experiments on board the spacecraft Ulysses.

Ulysses, decommissioned on June 30, 2009, was a joint robotic space probe to study the Sun by NASA and the European Space Agency (ESA). The launch of Ulysses was delayed until October 6, 1990 aboard Discovery (mission STS-41) due to the loss of its initially assigned carrier Challenger. It studied the Sun at all latitudes, breaking the limitation that the Sun had been only observed from low solar latitudes due to the Earth's orbit confined on the ecliptic plane. The mission was managed by JPL.

Today in History: The first American in space

Space Shuttle Challenger on Mission STS-8

On May 5, 1961, Navy Commander Alan Bartlett Shepard Jr. became the first American to travel into space on the Freedom 7 space capsule.

On this 52nd anniversary, I found a NASA postcard among my early postcard collections, sent from the Kennedy Space Center, Cape Canaveral, Florida, on December, 19, 1999. We sent the card to ourselves when we went to see the Space Shuttle Discovery launch for the 3rd Hubble Space Telescope Servicing Mission STS-103. It was launched from Pad: 39B on December 19, 1999, 7:50 p.m. EST. It was a night time launch since the sunset that day was 5:32 PM. It was our second attempt to drive 300 miles round trip from West Palm Beach to see the Discovery launch in two days. The previous day launch attempt on December 18 was scrubbed due to the weather. There were two more canceled launch attemps on December 6 and December 16, 1999 for technical reasons. We were debating whether to go again on December 19 as the forecast had 40% chance for bad weather. However, our determination paid off for an once-in-a-life-time experience.

Interestingly, the Challenger mission, STS-8 shown on the card, was the first night launch of the space shuttle. The nose of the shuttle was positioned away from the sun in order to test the flight deck's performance in extreme cold temperature. Night time launches were banned after the Shuttle Columbia accident in order to better monitor the foam falling off.

Pictorial Postmark at the Kennedy Space Center

The pictorial postmark had a space shuttle image with the text "Benefits on Earth". The stamp was a non-denominated 'H' stamps issued at the 'birthplace' of Uncle Sam in Troy, New York on November 9, 1988. The "H-series" stamp features Uncle Sam's Top Hat with stars and stripes on a white background. The stamp was valued at 33 cents for the First-Class, 1 ounce, letter rate effective January 10, 1999.

Space Day: the First Friday in May

STS-41C Mission Insignia for the Space Shuttle Challenger

The Space Day was first introduced in 1997. It is the first day in May every year. Space themed postcards are among my favorites. I would like to highlight this US-1999692 card to mark the Space Day for 2013 on May 3rd. The postcard shows the STS-41C mission insignia. Originally numbered as STS-13, it was NASA's 11th Space Shuttle flight, and the 5th for the Shuttle Challenger. It was launched on April 6, 1984 from the  Kennedy Space Center, and landed at Edwards Air Force Base on April 13, 1984.

I found quite a few space themed postcards in the Planetarium gift shop at the College of Southern Nevada. Programs are presented on the domed screen very Friday at 6:00 pm, 7:00 pm and 8:00 pm and every Saturday at 3:30 pm, 6:00 pm, 7:00 pm & 8:00 pm. Check their Event Calendar for the current line up. Weather permitting, the telescopes at the Student Observatory will be open for viewing After the 8pm presentation.

Clare has a blog post on the 10 Stamps for the Space Day. Hope I can collect them all some day.
