L+25 Years: STS-1's Young and Crippen

April 10, 2006 — Twenty-five years ago this week, two men embarked upon an unprecedented mission. Aboard the world's first spacecraft designed to be reusable, the experienced commander and rookie pilot would set many firsts over the two day space flight, setting the stage for the next chapter in U.S. space activities after the Apollo lunar program had come to an end. First however, STS-1 needed to prove that the winged Space Shuttle Columbia could safely launch into space as a rocket and return as an engine-less glider.

collectSPACE.com recently spoke with STS-1 Commander John Young and Pilot Robert Crippen via the phone about the 25th anniversary of their mission, their memories of the flight and its legacy. Although their conversations were separate, the following combines both of their comments:

Your mission has been described as "the boldest test flight in history." What made it such?

John Young (JY): "I think if you look at all the things we had to do, flying a winged launch vehicle into space without any previous unmanned test, it probably was very bold and we thought we knew a lot more than we did."

Did you realize it was "the boldest" at the time?

Robert Crippen (RC): "Some of my test pilot friends might challenge it — because there have been lots of important test flights — however the Space Shuttle was a unique test flight and both John and I knew that.

"It was the first that we had ever flown on a vehicle that hadn't been launched unmanned before into space, so that was truly unique. And then we were flying with the first solid rockets that had ever been used for human space flight. We were flying on a winged vehicle that would do reentry different than we had ever done before and come back in and land on a runway. So all of those were firsts — and test pilots truly love firsts — so it was a big deal for both John and I."

Pamiętam ten pierwszy start Columbii 12 kwietnia 1981 r. - pierwszy start wahadłowca w ogóle i od razu pełny sukces. Niebywałą odwagę i profesjonalność tych ludzi podziwiam do dziś. Weteran lotów orbitalnych John Young poleciał z astronautą nowicjuszem - Robertem Crippenem nowym ogromny statkiem kosmicznym. Wtedy to było niesamowite osiągnięcie, wielka chwila.  ;D

Sukces tym większy, że jak potem przeanalizowano dane po locie, to oceniono prawdopodobieństwo utraty załogi jak 1 do 12.
Ciekawe czy Bob Crippen, mimo pandemii, będzie obecny przy starcie Crew Dragon ?

Ciekawe jakie czynniki tak wysoko wywindowały ryzyko tego lotu? Są może dostępne jakieś przystępne analizy? Swoją drogą rzeczywisty wskaźnik ryzyka – ok. 1:67 też okazał się niemały.

Several media people have asked me about how risky STS-1 was. There were a lot of uninformed guesses circulating in 1981. Thirty years later, based on everything we knew, we back calculated the probability of loss of crew and vehicle to be 1 in 9. That is pretty risky.

Biorąc pod uwagę jak dużo elementów zostało uszkodzonych w trakcie startu oraz misji STS-1, to wcale nie takie dziwne, że ta misja była naprawdę ryzykowna. Kolejne w latach 80. - w zasadzie wcale wyraźnie bezpieczniejsze nie były...

40 Years Ago: Preparations Continue for STS-1
Aug. 25, 2020


Employees and their families view Columbia’s main engines during KSC’s Open House

In August 1980, while much work still remained to prepare Space Shuttle Columbia for its first flight to usher in a new era of a reusable crewed space transportation system, NASA managers confirmed March 1981 as the target launch date for STS-1. Significant recent accomplishments included the reinstallation of the main engines on Columbia after their recertification, continued installation of heat shield tiles on the vehicle’s surfaces, and tests of the orbiter as well as of the solid rocket boosters. The prime crew for the first Shuttle flight, John W. Young and Robert L. Crippen along with their backups Joe H. Engle and Richard H. Truly, continued to train for the mission and participated in some phases of the test activities such as a crew interface test and a full mission duration simulation. (...)

40 Years Ago: Six Months until the STS-1 Launch

Preparations for space shuttle Columbia’s first mission continued in October 1980, and managers remained optimistic that the initial flight could take place by March 1981, although April seemed like a more realistic possibility. The prime crew for STS-1, John W. Young and Robert L. Crippen, spent time in Columbia’s cockpit and mission simulators maintaining their proficiency for the historic mission. Multiple tests of the Space Shuttle Main Engines (SSME) progressed toward certifying them for flight. Engineers in the Orbiter Processing Facility (OPF) at NASA’s Kennedy Space Center (KSC) made minor modifications to Columbia’s SSMEs and continued installing the orbiter’s thermal protection system tiles, with only a few hundred remaining to be attached. Young and Crippen practiced landing the space shuttle using a modified airplane at KSC. Mission controllers at NASA’s Johnson Space Center (JSC) in Houston completed another full mission simulation and a ship used to recover the Solid Rocket Boosters (SRB) began sea trials.
