Apollo 11

November 15, 2008

“That’s one small step for man, one giant leap for mankind.” The words uttered by Neil Armstrong when he took the first step on the surface of the Moon on 20th July 1969. As part of a 3-man team, the other two astronauts were Michael Collins and Buzz Aldrin, the spacecraft Apollo 11 landed on the Moon and made history.

From this historical feat, toy manufacturers created toys of the spacecraft Apollo 11, which is a bit of history by now.

^ Apollo 11, battery powered.

^ Measuring about 50cm, powering up Apollo 11 with 4AA size batteries will see the spacecraft travel horizontally for about 2 feet before coming to a halt. A lever slowly raises the nose of the spacecraft pointing upwards adopting the take-off position. Red lights will start to flash and some whirring noises can be heard that simulate take-off. It will last for about 15 seconds before the lever retracts that brings the spacecraft back to a horizontal position. It will make an about turn, travel for about 2 feet, and the take-off process begins again.

^ Not manufactured nor designed by NASA. Rather, it is from a Japanese toy manufacturer.

If you have thinking of becoming an astronaut, perhaps this link to NASA homepage will provide an insight to realising your dream of that spacewalk.

Solar eclipse on the internet

Wondering when will you will have the opportunity to watch the solar eclipse unless you make a trip to the area where it can be seen? Perhaps, it could just be right in the comfort of your home in front of your PC.

Here’s the article about Friday’s remote solar eclipse will be on Internet.

International Space StationOrbital Tracking Information in real time
About the Space Station (as of Dec. 2006)
Weight : 471,444 pounds
Habitable Volume : 15,000 cubic feet
Dimensions Span of Solar Arrays : 240 feet Length : 146 feet from Destiny Lab to Zvezda; 171 feet with a Progress docked Truss 191 feet. Height : 90 feet
Computers at Johnson Space Center in Houston, Texas, receive International Space Station telemetry data via satellite downlink, process the data and make it available through the Information Sharing Protocol (ISP). The Advanced International Space Station Tracking Monitor uses ISPresso, a Java version of the ISP client library which allows Java-enabled browsers to tap directly into ISP telemetry streams. Using ISPresso, your browser will receive the ISP data directly from the ISP stream delivered to the Human Space Flight Web server from the Mission Control Center. What information can be obtained from the tracking monitor?

The blue line tracks the International Space Station’s path over the ground.
The red circle around the International Space Station represents its horizon — the area on the ground from which the orbiter is visible.
Header Information : GMT and Houston and Moscow times are displayed in DAYS/HOURS:MIN:SEC format.
Footer Information : The footer contains information about the vehicles. Parameters include latitude, longitude, phase, signal, altitude, speed, roll, pitch, yaw, temperature, humidity and air pressure. Also included is a Zoom feature. This feature can be toggled on (+) or off (-). Turning this feature on will open a window that shows a view of the selected vehicle over a zoomed, detailed view of the Earth (mountains, rivers, etc.)

1. New Moon.
2. Waxing Crescent.
3. First Quarter.
4. Waxing Gibbous.
5. Full Moon.
6. Waning Gibbous.
7. Last Quarter.
8. Waning Crescent.

The phases of the moon are caused by the relative positions of the earth, sun, and moon. The moon goes around the earth, on average, in 27 days 7 hours 43 minutes. The sun always illuminates the half of the moon facing the sun (except during lunar eclipses, when the moon passes thru the earth’s shadow). When the sun and moon are on opposite sides of the earth, the moon appears “full” to us, a bright, round disk. When the moon is between the earth and the sun, it appears dark, a “new” moon. In between, the moon’s illuminated surface appears to grow (wax) to full, then decreases (wanes) to the next new moon. The edge of the shadow (the terminator) is always curved, being an oblique view of a circle, giving the moon its familiar crescent shape. Because the “horns” of the moon at the ends of the crescent are always facing away from the setting or rising sun, they always point upward in the sky. It is fun to watch for paintings and pictures which show an “impossible moon” with the horns pointed downwards.Images & Contents Credit : NASA
