Challenger and crew clear the tower

Where do I start? Seven amazing, wonderful, smart people lost their lives today. None of us can come to terms with the reality of what happened.

The morning was cold. We opened the water valves on Launch Pad 39B overnight to keep the lines from freezing and ice was all over the pad. Still, that should have not been a problem, nor caused a disaster. We had a delay of two hours because of an equipment failure on the pad, but the fuel and crew were loaded normally and Challenger launched at 11:38 AM.

There were no warnings, no alarms, no indication of a problem. At 73 seconds after liftoff a massive cloud surrounded the vehicle and we lost sight of it. Then the Solid Rocket Boosters (SRBs) emerged at the top of the cloud and continued on followed by pieces of debris. We knew that something had happened but it was over a minute before it became apparent that the Orbiter had not survived.

The impact on everyone was a wall of emotions. The feeling of loss because the seven astronauts were our family. The feeling of empathy for the astronaut’s families for their loss. The feeling of anxiety as to if there was something we did that caused this tragedy and the need to find answers as quickly as possible. The loss was made even harder as we all watched helplessly seeing the remains of STS-51L fall into the ocean. Many of us held out hope of the miracle until it became apparent there would not be one.

Much of what happened does not make sense. Any rocket-based vehicle is a flying explosion waiting to happen, but everything possible is done to keep the volatile chemicals from interacting until they reach the nozzle. The cloud was apparently the result of a sudden burn of fuel from the External Tank, which doesn’t necessarily mean it was a violent explosion. If there was an explosion, why did the Solid Rocket Boosters (SRBs) escape, seemingly untouched. Challenger has been cursed with Main Engine problems, so some wonder if one of them failed causing the External Tank (ET) to breach and the fuel to burn, but again, why didn’t the SRBs also explode? 

There has been discussion that the cold might have caused a problem with the seal around the joint of a SRB, but why would that destroy the External Tank (ET) and Orbiter, but have seemingly little or no impact on the SRBs? It is apparent that the ET is key to explaining what happened. A joint could fail and hot gas escape that is aimed directly at the ET, which could cause an explosion, but a joint is 360°around and less than 25% of a joint faces at or near the ET. Odds of a first time failure of a joint facing the ET after 25 missions are ridiculously low.

The biggest question on everyone’s mind is the one no one wants to discuss. What happened to the crew? The Orbiter and ET emerged from the cloud in fragments and some were large enough to be the area where the crew sat during launch. Most of us believe that they were killed instantly, but no one will rest peacefully until we know what happened to them. 

The scope and breadth of this tragedy is far beyond what I could have imagined. Somehow we all have to move forward, but we’re all trying to deal with what happened. Moving forward doesn’t seem possible, right now. The first step in moving forward will be to understand what happened.

Teacher in Zero G - Christa McAuliffe trains for STS-51L

The launch of STS-51L is now scheduled for Monday. We were scheduled for a liftoff Sunday morning, but tomorrow’s weather is predicted to be as bad or worse than today’s, which was foggy until about noon. Hopefully, we can get Challenger off the ground on the 27th and then focus on Columbia’s next launch in March.

The seven astronauts going up with Challenger on Monday include our first teacher. The Teacher in Space Project was announced by President Ronald Reagan in the Fall of 1984. Last Summer Vice President George Bush announced that Sharon Christa McAuliffe was selected as the first Teacher in Space from 11,000 applicants. Christa teaches in Concord, New Hampshire and submitted her application on the last day they were being accepted.

Mrs. McAuliffe, as she is known in the classroom, has always dreamed of being part of the space program and is pleased to have the chance to take her classroom skills into space. Christa talked about the opportunity she has been given, saying:

Imagine me teaching from space, all over the world, touching so many people’s lives. That’s a teacher’s dream! I have a vision of the world as a global village, a world without boundaries. Imagine a history teacher making history!

In addition to Mrs. McAuliffe will be four members of the ‘Class of 1978.’ Commander Francis R.’Dick’ Scobee, Mission Specialists Ellison ‘El’ S. Onizuka, Judith ‘Judy’ A. Resnik, and Ronald ‘Ron’ E. McNair were all selected as astronaut candidates in January of 1978. The other two crew members are Pilot Michael J. Smith and Payload Specialist Gregory Jarvis.

Commander Dick Scobee noted the opportunity of the Teacher in Space Project when he said:

“My perception is the real significance of it, and especially a teacher, is that it will get people in this country, especially the young people, expecting to fly in space. That’s the best thing that can happen to our program. The short-term gain is a publicity gain. The long term gain is getting expectations of the young people in this country to the point where they expect to fly in space, they expect to go there, they expect this country to pursue a program that allows it to be in space permanently to work and live there, to explore the planets.”

The Teacher in Space Project is just one more part in keeping America a world leader by bringing space down to Earth. On Monday we will take the next step with the beginning of mission STS-51L…assuming the weather cooperates!

TDRS satellite to be launched by Challenger STS-51L

This afternoon’s launch had to be scrubbed. The weather here was cool and damp, but the real problem was the weather at one of the abort landing sites. We have an alternate abort site but they cannot handle a nighttime landing (an abort on this side of the world would be a night landing there,) so the launch was rescheduled for tomorrow morning in case we have to activate the alternate abort site. That would allow Challenger to land in daylight at the alternate site if they have to abort.

The launch was then pushed back another day because of the morning versus afternoon liftoff. The problem is that we have a set amount of work to do and it was quickly determined that we would not be ready for launch by Saturday morning. Mission Control then moved the launch to Sunday morning. 

SPARTAN 203 satellite to have its eye on Halley's Comet

Once we finally do get Challenger in orbit, the STS-51L mission has several goals. One will be to launch the TDRS-2 satellite, which is a communications relay station for analog and digital signals. These satellites are the next generation in communication technology allowing information to be transmitted around the world in seconds. Another small satellite called SPARTAN 203 is being deployed to observe Halley’s Comet, which will reach its perihelion (closest approach to the Sun) on February 9, 1986.

In addition, this mission will send our first “Teacher in Space.” More about that tomorrow.

High Temp: 75° F Low Temp: 53° F

Earth looking out through Challenger cargo bay

Tomorrow we should launch Challenger on its 10th mission. Temperatures were seasonal today; however, the weather is questionable as another cold front is moving through tomorrow. We won’t know if the launch is a go or not until a few hours or less before liftoff.

Beyond weather considerations, there are thousands of things that have to be perfect before a mission is given a “go for launch.” It’s a wonder we ever get a Space Shuttle off the ground. Every individual component of the Orbiter, the External Tank (ET), and the Solid Rocket Boosters (SRBs) is rated in one of five categories of impact on the mission, vehicle, and/or crew if the part fails. The ratings are as follows:

  • Criticality 1 (C1) – Loss of vehicle or crew if the component fails
  • Criticality 2 (C2) – Loss of mission
  • Criticality 3 (C3) – Component will not have fatal impact on crew, vehicle, or mission if it alone fails
  • Criticality 1R (C 1R) – Redundant component, but loss of vehicle or crew if both primary and redundant components fail
  • Criticality 2R (C 2R) – Redundant component, but loss of mission if both primary and redundant components fail

Any component that is not rated C3 and has a known issue not only stops the countdown, but the entire program, until resolved. When trying to put seven people and tons of cargo into Earth orbit, there are a lot of components that fall into the C1, C2, C 1R, or C 2R categories. Safety can be annoying, but it save lives.

Crew of Challenger STS-7 mission working in space

That said, it is impossible for any human, regardless of how careful, intelligent or well-educated, to be able to anticipate every possible problem. Exploration of uncharted territory comes with a price and that price is the loss of human life. Over 700 people died trying to reach the North Pole and even there we have air to breathe, water, and survivable temperatures if properly dressed. In space there is no air, no water, and a human dies if directly exposed to the vacuum of space.

Space travel is risky on the best of days. Astronauts are put in a ship that is designed to be as light-weight as possible with no significant armor or shielding around them. They are attached to two highly explosive solid rocket boosters that would flatten a small city if they exploded, connected to a massive tank filled with hydrogen and oxygen that has a nasty tendency to flash burn if it comes in contact to even a small flame or spark.

In addition, the speeds and the pressures that astronauts experience are unlike any other reality most humans can imagine. There is no doubt that human life will be lost in the pursuit of space exploration. We will do everything we can to safeguard our astronauts, but at some point we will discover what we did not anticipate. At some point an accident will occur on the ground or in flight. We will investigate, learn where we failed and moved forward again.

For centuries humans sailed near the coastline because no one knew what lie out across the sea. Staying close to shore taught us how to sail, while minimizing the risk. Even then ships sank and people died. The Space Shuttle program is our way of sailing near the coastline. We send people up into low Earth orbit and learn how to ‘sail’ in space. After a few decades we will be ready to go out into open space, just as ships were ready to cross open seas.

There are some who ask why should we reach out into space. That is probably what some people asked sailors who went off to explore the new world. But those brave men sailed off into uncharted waters and everything we now enjoy in the United States of America is due to those who took the risks to leave behind the safety of ‘the known’ in order to explore the unknown.

The answer to those people who want to know ‘why’ is simply this: we don’t know why…YET. After we get there we will know why it was so important we went. That is the way it has always been when exploring the unknown. That is the way it will always be.

(NOTE: The following is a fictionalized account of the 15 days in January 1986 leading up to the Challenger Space Shuttle Disaster. The character’s account is fictional; however, the details of weather and Space Shuttle events are based on known historical facts.)

Titusville, Florida
Thursday, January 16, 1986
High Temp: 69° F  Low Temp: 52° F

They waved off the Columbia landing today. Weather conditions here and at the backup landing site at Edwards AFB were unacceptable. It was drizzly here today and cloudy in California. Personally, I think that landing at Edwards should only be an emergency. When an Orbiter lands at Edwards it costs over $1.5 million dollars to get it back here and we lose a week in turnaround time. If we can’t land because the weather at Kennedy Space Center we could wait for several days and still save money and time on the recovery of the Orbiter.

Atlantis (STS-61-B) was the last mission and it landed at Edwards on October 7th and it was October 12th before it was back here. Once it got back here we had the fastest turn around in the history of the program. Atlantis was out to the launch pad by November 12th. Had it landed here at Kennedy Space Center (KSC) it would have been ready to go by November 7th. The only reason to land at Edwards is if the next launch for that vehicle will be from Vandenberg AFB, and our first launch from there isn’t going to happen until July.

STS-61-B Atlantis landing at Edwards on October, 7, 1985

Of course, delays have their costs, too. Every time we scrub a landing or launch we are wasting money because we all get paid whether the Orbiter comes or goes,…or doesn’t. Still, if we are going to prove the value of the program we need to be able to get the Orbiters back in the air as quickly as possible, and that means landing at KSC.

Fortunately, tomorrow will be warmer and hopefully dryer. It should be a good day for a landing. Columbia has been a pain in the neck. It should have been up and down by Christmas and now were almost a month later and still waiting for it to land. Once Columbia is back home we are scheduled to launch Challenger next week.
