Discovery’s a “Go” for Independence Day

After analysis of available data, the Mission Management Team has given a “go” for Tuesday’s launch of Space Shuttle Discovery to the International Space Station.

During a routine inspection Sunday night after the draining of the external fuel tank, a crack was discovered in the foam near a bracket that holds the liquid oxygen feedline in place. It is believed that the rain experienced during Sunday’s launch attempt caused water to run down the feedline and form ice near the top of the strut next to the feedline bracket. As the tank warmed and expanded, the ice that formed most likely pinched the foam on the top of the strut, causing a crack and eventual loss of the small piece of foam. The Mission Management Team met Monday at 6:30 p.m. EDT to discuss the results of the information before making a final decision regarding Tuesday’s launch attempt.

Extensive analysis showed that the area around the crack is intact and there is no concern for heating as there is adequate foam in place on the strut. Additional borescope inspection of the tank revealed that the bracket has no cracks.

Currently, there is a 60 percent chance of favorable launch weather for Tuesday and a 40 percent chance of favorable weather for Wednesday according to Air Force First Lt. Kaleb Nordgren of the 45th Weather Squadron. If the weather cooperates this will be the first Independence Day launch of a space shuttle!

A Fourth of July Discovery Launch would nicely compliment STS-4 Columbia‘s Fourth of July, 1982 landing at Edwards AFB in California.

SpaceLine.org — July 4, 1982 – 9:09:31 a.m. PDT at Runway 22, Edwards Air Force Base, California. Rollout distance was 9,878 feet. Rollout time was 73 seconds. Mission duration was 7 days, 1 hour, 9 minutes, 31 seconds. Landing occurred during the 113th orbit.

This was the first landing on the 15,000-foot concrete runway at Edwards.

I was lucky enough to have been on Rogers Dry Lake on July 4th, 1982 and witnessed the arrival of STS-4 at Edwards and also to observe NASA’s 747 piggy-back departure with another of the Space Shuttle Fleet in tow that same Day – spectacular! President Reagan was there that day, although I didn’t get close enough to see him.

Spouting More Hot Air than Al Gore

Who are Al Gore and his enviroloons going to blame for this reckless discharge of greenhouse gasses?

An Alaskan Volcano Erupts

What is happening to that volcano? It’s erupting! The first person to note that the Aleutian Cleveland Volcano was spewing ash was astronaut Jeffrey N. Williams aboard the International Space Station. Looking down on the Alaskan Aleutian Islands two weeks ago, Williams noted, photographed, and reported a spectacular ash plume emanating from the Cleveland Volcano. Starting just before this image was taken, the Cleveland Volcano underwent a short eruption lasting only about two hours. The Cleveland stratovolcano is one of the most active in the Aleutian Island chain. The volcano is fueled by magma displaced by the subduction of the northwest-moving tectonic Pacific Plate under the tectonic North America Plate.

Droids in Space

I’m sure there is a purpose in all this besides a science project . . .

NASA – Droids on the ISS

Six years ago, MIT engineering Professor David Miller showed the movie Star Wars to his students on their first day of class. There’s a scene Miller is particularly fond of, the one where Luke Skywalker spars with a floating battle droid. Miller stood up and pointed: “I want you to build me some of those.”

So they did. With support from the Department of Defense and NASA, Miller’s undergraduates built five working droids. And now, one of them is onboard the International Space Station (ISS).

Didn’t NASA Astronauts refer to the reduced gravity aircraft as the “vomit comet?”

Toto, We’re not in Barstow Anymore

Finally! The Mars Rover “Opportunity” returned an image of the Martian Landscape that doesn’t look like it was taken in the Mojave Desert. The eerie textures and coloring lend an other-worldliness appearance to this image, unlike the images that comedian Dennis Miller asserts “Looks like Barstow!”

As NASA’s Mars Exploration Rover Opportunity continues to traverse from “Erebus Crater” toward “Victoria Crater,” the rover navigates along exposures of bedrock between large, wind-blown ripples. Along the way, scientists have been studying fields of cobbles that sometimes appear on trough floors between ripples.

They have also been studying the banding patterns seen in large ripples.This view, obtained by Opportunity’s panoramic camera on the rover’s 802nd Martian day (sol) of exploration (April 27, 2006), is a mosaic spanning about 30 degrees. It shows a field of cobbles nestled among wind-driven ripples that are about 20 centimeters (8 inches) high.

This is a false-color rendering that combines separate images taken through the panoramic camera’s 753-nanometer, 535-nanometer and 432-nanometer filters. The false color is used to enhance differences between types of materials in the rocks and soil.

OK — I admit that this is a “false color” image and isn’t representative of the natural sunlight on Mars, but if you were to pump sunlight up to the amount the Earth gets, you just might get a picture like this.

Space Monkeys

This is sort of a neat little gadget. It would be nice to have one of these handy for help around the house and garden too.

NASA – Limber Robot Might Hitchhike to Space

Lemurs, those wide-eyed, active, monkey-like animals running around the island in the movie “Madagascar,” are known for their ability to leap. A robotic lemur being tested at NASA’s Jet Propulsion Laboratory moves more slowly, but might someday take its own giant leap – by going into space with astronauts.

“Lemur,” short for the Limbed Excursion Mechanical Utility Robot, was originally conceived to help maintain future spacecraft and space stations. It weighs in at just 26 pounds (12 kilograms) and is small enough to hitch a ride on the space shuttle or NASA’s planned crew exploration vehicle.

“Lemur could be an astronaut’s pet monkey,” says JPL engineer Brett Kennedy, principal investigator for the robotic project. “It can perform tasks that are too small for astronauts to do easily. It’s built to get into the nooks and crannies of a structure.”

STS-1 Pilot Crippen Awarded Medal of Honor

I was very fortunate to have been on Rogers Dry Lake at Edwards AFB on the day that Crippen and Young arrived on the lakebed in STS-1. The landing happened so quickly that I was astonished. From the twin sonic booms overhead to the touchdown on the lake seemed almost instantaneous — but I shall never forget it. I purchased a button from a lakebed entrepreneur that said “I SAW A SPACESHIP LAND ON EARTH.”I attached the button to my old cowboy hat that I wore in the desert sun. I still have that button somewhere . . .

Commander John Young received his award in 1981, and Crippen’s award was overdue in my opinion. Congratulations Bob Crippen!

NASA — First Shuttle Pilot Crippen Gets Congressional Space Medal of Honor

Former NASA astronaut Bob Crippen, pilot on the first space shuttle mission in 1981, has been honored with the nation’s highest award for spaceflight achievement, the Congressional Space Medal of Honor.

Yesterday evening, at a gala celebrating the 25th anniversary of the first Space Shuttle mission, Robert Crippen became the 28th astronaut in history to be awarded the Congressional Space Medal of Honor.

The surprise presentation by NASA Administrator Michael Griffin was made before the gathered audience at the National Air and Space Museum, including Crippen’s STS-1 commander and 1981 medal recipient John Young.

“This medal, awarded by the Congress of the United States, commemorates publicly what all of us who know Bob Crippen already understood: he is an authentic American hero,” said Griffin.

“It was such a surprise. I am totally overwhelmed,” said Crippen in a statement released after the ceremony. “Just look at the names of the people who are on the list. They are heroes in the truest sense of the word and I can’t believe someone would think to include me in such distinguished company. I’m so honored.”

The award commends astronauts whose efforts in space exemplify actions of tremendous benefit to mankind. The medal, which has also been given to astronauts who died in the line of duty, was last presented in 2004 to the crew of STS-107. The award was first given in 1978 to astronauts Neil Armstrong, Frank Borman, Pete Conrad, John Glenn, Alan Shepard, and posthumously to Virgil “Gus” Grissom.

Vandenberg Minotaur Lights

Because of rainclouds in our area, we missed this spectacular light show last evening. However, SpaceWeather.Com, published a couple of nice images of the light show.

From Spaceflight Now:

Six tiny satellites sped into space Friday evening aboard an ultra-fast rocket booster, beginning a five-year mission to examine Earth’s atmosphere and the underlying hints of climate change by employing a novel technique.

The $100 million COSMIC mission that partners the U.S. and Taiwan roared away from the wet and foggy Space Launch Complex 8 on the southern end of Vandenberg Air Force Base in California at 6:40 p.m. PDT (9:40 p.m. EDT; 0140 GMT).

The Orbital Sciences Minotaur rocket was gone in a flash, almost instantly disappearing from view of launch pad cameras. The liftoff was delayed an hour-and-a-half after an initial countdown attempt was aborted because of a problem with the system monitoring rocket data.
