The Challenger seven remembered 30 years after STS-51L

no alt

Today marks the 30th anniversary of the loss of the Space Shuttle Challenger and her seven crewmembers in the skies over Florida. As the world memorializes the tragic event of January 28, 1986, we pause to honor the Challenger crew and the reasons they chose to fly aboard Challenger thirty year ago today.


The Space Shuttle Program allowed more people to venture into space than any other program was capable of. It furthered our ability to maintain a permanent, international human presence in space.

2016-01-28-045824But above all, it enabled steady, progressive, and sometimes huge advancements in scientific, medical, astrophysical, and educational knowledge.

For the seven crewmembers of STS-51L and the Shuttle Challenger, this was the reason they flew. This was the cause for which they all climbed aboard Challenger.

STS-51L was, after numerous manifest realignments, the 25th flight of the Space Shuttle Program and the 10th flight of Orbiter Challenger.

Like many missions before it, STS-51L was a multi-disciplinary flight, designed to conduct astrophysical, biomedical, educational experiments and deploy two satellites (one permanent, one recapture) over the course of a seven flight day (six calendar day) mission.

Screen Shot 2016-01-27 at 10.26.28Unique to STS-51L, however, was the planned first-ever direct human observations of Halley’s comet from space.

Like all Shuttle missions, STS-51L was tightly choreographed to maximize the efficiency of its mission objectives while ensuring that all critical operations which required direct communication with the ground were performed during active comm passes.

Following liftoff from the Kennedy Space Center, Flight Day 1 (FD-1) was scheduled to see the STS-51L crew arrive in orbit and immediately begin two periods of scheduled high activity.

First, the crew was to check the readiness of the TDRS-B (Tracking and Data Relay Satellite – B) communications satellite inside the Shuttle’s payload bay.

A10This would have been followed by lunch and then deployment of TDRS-B and its Inertial Upper Stage booster.

The crew was then scheduled to perform a series of separation maneuvers from TDRS-B followed by the commencement of the first sleep period about 12 hours after liftoff.

On FD-2, the Comet Halley Active Monitoring Program (CHAMP) experiment was scheduled to begin.

The crew was also scheduled to tape the initial “teacher in space” recordings before firing the orbital maneuvering engines to place their Shuttle orbiter into the correct 152-mile orbital altitude from which the SPARTAN-203 satellite would be deployed the next day.

2016-01-28-045341FD-3 was then to see the crew begin pre-deployment preparations on the SPARTAN-203 satellite (also called the Halley’s Comet Experiment Deployable).

SPARTAN-203 was scheduled to be deployed using the Remote Manipulator System (RMS) arm, after which the crew would back their Shuttle Orbiter away from SPARTAN to a distance of 90 miles.

On Flight Day 4, the crew was then to begin closing the distance between the Shuttle and SPARTAN-203 while fluid dynamics experiments, started on FDs 2 and 3, continued on the mid-deck.

Live telecasts were also planned with numerous schools around the United States for FD-4.

Screen Shot 2016-01-27 at 10.36.39FD-5 was subsequently scheduled to have the crew rendezvous with SPARTAN, grab it with the RMS, and stow it safely in their Shuttle’s payload bay.

This was to occur simultaneous to the continuation of numerous experiments on the mid-deck.

On Flight Day 6, the crew was scheduled to spend the majority of their day closing out the various experiments on the mid-deck while at the same time running through a series of re-entry preparations, including flight control checks, test firings of maneuvering jets needed for re-entry, and cabin stowage.

Crew news conferences were scheduled following the lunch period.

2016-01-28-045718Then, on FD-7, assuming good weather at Kennedy, the crew was to make final preparations for deorbit and entry into the atmosphere.

After a successful mission, the STS-51L crew was scheduled to land at the Kennedy Space Center 144 hours and 34 minutes (six days and thirty-four minutes) after launch.

With this mission framework, STS-51L needed a seven-member crew.

Ultimately, veteran Shuttle astronaut Lt. Col. Francis R. Scobee was selected to command the mission, with rookie Capt. Michael J. Smith chosen as pilot.

Veteran fliers Dr. Judith A. Resnik, Dr. Ronald  E. McNair, and Lt. Col. Ellison S. Onizuka were selected as mission specialists.

Also ultimately selected for the flight were Capt. Gregory Jarvis and civilian teacher S. Christa McAuliffe – both to serve as payload specialists.

Honoring The Crew:

Francis R. “Dick” Scobee (Lt. Col., U.S. Air Force, Ret.)

Francis R. Scobee was born on 19 May 1939 in Cle Elum, Washington.

In 1983, she was selected to fly her first mission on the maiden voyage of Discovery on the STS-41D mission.

During the initial launch campaign for STS-41D in June 1984, a post-main engine start pad abort occurred, resulting in an emergency shutdown of Discovery’s engines and the subsequent delay of the launch for two months.

Resnik’s first flight lifted off from the Kennedy Space Center on the morning of 30 August 1984, making her the second American woman to fly in space and the first American-Jewish astronaut.

During STS-41D, Resnik participated in the activation of the OAST-1 solar cell wing experiment, deployment of three satellites, operation of the CFES-III experiment as well as the student crystal growth experiment, and photography experiments using the IMAX motion picture camera.

Screen Shot 2016-01-27 at 14.10.28Resnik and her crewmembers also used Discovery’s RMS arm to successfully remove hazardous ice particles from the Orbiter.

Resnik and the STS-41D crew landed safely with Discovery at Edwards Air Force Base on 5 September 1984 after 144 hours and 57 minutes in orbit, after which Resnik returned to non-flight duties within the astronaut office.

In 1985, Resnik was then assigned as a Mission Specialist and Flight Engineer for STS-51L.

Resnik was posthumously awarded the Congressional Space Medal of Honor on 23 July 2004 along with her fellow Challenger crewmembers.
