Challenger Disaster 25 years Ago Today

I was driving to work that morning with the radio on and heard a news report that the space shuttle Challenger exploded 73 seconds after launch that morning. Later, I was able to see the video. I was sad for the families, but more so for the American spirit.

Then there was the President - Ronald W. Reagan whos speech tried to make things right again. We would later discover the reasons why the Challenger Disaster took place and tried to correct those mistakes.

On Michelle Malkin's website today, she ran President Reagan's video of his speech. She also posted the transcript of that speech.

Also included in that post is the most beautiful poem (my opionion) I have ever heard in my life... High Flight by John Gillespie Magee, Jr. I'm going to copy and paste that poem here into this post. But please use the link info below to go to her site to read President Reagan's speech. Searching on YouTube, I have randomly selected a link to view the explosion and here it is: http://www.youtube.com/watch?v=EaKSrOpLJPo .



High Flight — John Gillespie Magee, Jr

Oh! I have slipped the surly bonds of Earth
And danced the skies on laughter-silvered wings;
Sunward I’ve climbed, and joined the tumbling mirth
Of sun-split clouds, — and done a hundred things
You have not dreamed of — wheeled and soared and swung
High in the sunlit silence. Hov’ring there,
I’ve chased the shouting wind along, and flung
My eager craft through footless halls of air. . . .

Up, up the long, delirious burning blue
I’ve topped the wind-swept heights with easy grace
Where never lark, or ever eagle flew —
And, while with silent, lifting mind I’ve trod
The high untrespassed sanctity of space,
Put out my hand, and touched the face of God.

Orbital Sciences Corp Offers Up Shuttle Replacement



The Dulles, Viginia, based Orbital Scien
ces Corp. announced on Tuesday, that it had
officially submitted a proposal to the National Aeronautics and Space Administration to build a winged space vehicle for astronaut transportation to and from earth orbit once NASA’s space shuttle is retired.

The design is of the "blended lifting body" type. Its design history goes back to 2002/2003 when Orbital did a study for NASA back then. The vehicle is designed with four seats allowing room for commercial passengers.

This new vehicle would normally use the Atlas V rocket as its booster and return for a conventional landing on a runway after its mission was completed.

Lockheed Martin Corp however, is going along with a capsule sim
ilar to Apollo/Orion with parachute landing.

My personal opinion on this matter is that I hope Orbital beats the pants off of the Lochkeed Martin proposal. Does anybody remember VentureStar? I personally do not want to see our nation just turns its back to the idea of a winged spacecraft that is able to land on a regular runway.


UPDATE December 18, 2010: At the NASA Dryden space center, a 15% scale model of Sierra Nevada Corporation's Dream Chaser spacecraft design was test dropped from a helicopter.
The company's full size version is based upon NASA's HL-20 lifting body. The Sierra Nevada Corporation's (SNC) Dream Chaser is designed to carry up to seven people to the ISS and back. It will be launched vertically on a Atlas V rocket and recover horizontally on conventional runways.

Using a Bell 206B3 Jet Ranger helicopter, the model was attached to a 100-foot long cable and dropped from an altitude of 14,000 feet. Landing this time was done via a parachute. The scale model was built by a team of experts from SNC and the Research and Engineering Center for Unmanned Vehicles at the University of Colorado at Boulder (CU).

The NASA Authorization Act of 2010

The following is copied entirely from the Commerce, Science, & Transportation website. Senator Kay Bailey Hutchison (Ranking Member) and Senator John D. Rockefeller IV (Chairman).

Begin quote.

The bill would authorize NASA appropriations for FY 2011-2013 with the same top-line budget values as the President’s request to Congress. The bill would support an overall growth in science, aeronautics, and space technology and define a long-term goal for human space flight to expand a permanent human presence beyond low-Earth orbit. Key objectives of this goal would include full utilization of the International Space Station (ISS), determining the ability of humans to live in space for extended periods of time, maximizing the role of space exploration and technology in current and future missions, advancing knowledge and inspiring young people into higher education, and building upon international partnerships.

Human Space Flight. The bill would:

*Couple human space flight efforts to national and global needs and challenges;
Provide a sustainable exploration program to incorporate new technologies and in-space capabilities;

*Require immediate development of a heavy-lift capability and continued support of an exploration crew vehicle to be capable of supporting missions beyond low-Earth orbit starting in 2016; and

*Support a sound performance and cost framework by maximizing use, where possible, of the workforce, assets, and capabilities of the Space Shuttle, Constellation, and other NASA programs.

Space Technology. The bill would:

*Invest in exploration technologies and robotic capabilities that are tied to the overall exploration framework and support U.S. innovation and competitiveness.

Commercial Cargo and Crew. The bill would:

*Continue to support commercial cargo development and provide additional funds to meet launch infrastructure requirements and accelerate development activity; and

*Expand the Commercial Crew Development Program in 2011 for concept development and supporting activities, while requiring a number of studies to ensure effective oversight of the potential initiation of a commercial crew capability procurement program no earlier than 2012.
International Space Station. The bill would:

*Extend the ISS to at least 2020 to support international and commercial collaboration and growth, research, and technology development to maximize the scientific return on the significant investment in the ISS;

*Establish an independent non-profit to work with NASA to fully develop the ISS U.S. segment as a National Laboratory; and

*Require an assessment of ISS requirements for parts and equipment needed to ensure its full functionality through 2020.

Shuttle Retirement and final “Launch on Need” Mission. The bill would:

*Authorize an additional Shuttle flight, contingent on a safety review, to provide necessary support for the extension of the ISS.

Science and Aeronautics. The bill would:

*Protect a balanced portfolio for NASA, including full funding of aeronautics and Earth and space science.

Education. The bill would:

*Support new education initiatives, such as teacher training programs, to reinforce NASA’s role in developing a workforce with strong science, technology, engineering, and mathematics skills; and

*Increase the investment in NASA EPSCoR (Experimental Program to Stimulate Competitive Research) and NASA Space Grant program.

Rescoping and Revitalizing Institutional Capabilities. The bill would:

*Require NASA to examine alternative management models for NASA’s workforce, centers, and capabilities, while enforcing short-term prohibitions on major center displacements and reductions-in-force until the study is completed.

Forty-One Years Ago...

Forty-One Years Ago...

Forty-one years ago humans took their first step on another world and our universe changed. I was NINE years old when this took place. I am FIFTY years old today as I write this blog. And I feel like we have not done a damn thing since.

There was the space truck (i.e the Space Shuttle). Then EVENTUALLY, there was a orbital space station for the space truck to go too. Along the way, we lost two of those dump trucks and on the last one, I lost a former Air Force ROTC classmate who was the commander of that ill-fated mission. I remember I was in a light sleep that morning when I heard the sonic booms and I thought, "Uh oh. Some poor SOB out of Clovis (New Mexico) is going to get their ass chewed out when they return to base.

Forty-One years have passed...and I feel like we still haven't done a damn thing but spin our wheels so to speak. One study after another study. Just enough for the politicians to get through another election cycle and NASA not to do anything really important as far as Manned Space Flight goes.

I fear now that I will not live long enough to see Man land on Mars. I really, really hate that feeling. I really hope that I am wrong on that.

Forty-One Years Ago...

Will the Shuttle ever launch again - maybe?

NASA will once again try to launch space shuttle Discovery on the latest construction trip to the ISS(International Space Station) 220 miles above Earth. Lift-off is set for 7:43pm Sunday evening from the Kennedy Space Center in Florida. The meteorologist as predicting that there will be a 80 percent chance that the weather will be suitable for launch tonight.

Problems have been plaguing this launch. One was the satellite collision last month and they had to check the debris orbits to see if it would be safe for a launch. Engineers also had to replace seals in fuel vent line. Hydrogen gas began to leak from the shuttle's fuel tank which is a potential fire hazard. While the seals were replaced, the cause for the leak is still unknown according to the reuters.com news article posted by Irene Klotz (March 15, 2009, 11:36am EDT).

NASA is up against a time schedule to avoid a conflict with a Russian Soyuz mission that will replace the station's primary crew on April 7, 2009.

This mission's cargo is the fourth and final solar power module for the U.S. section of the station. That solar panel module weighs in at 16 tones and is to complete the 11-segment exterior backbone or spine of the space station. This is to be the first of five missions to the space station this year for the space shuttle.
UPDATE: Well- Discovery managed to lift-off after all.
