STS-95 Fact Sheet

Written and Edited by Cliff Lethbridge

 

STS-95 -- Discovery

 

92nd Space Shuttle Mission

25th Flight of Discovery

 

Crew:

 

Curtis L. Brown, Commander

Steven W. Lindsey, Pilot

Scott E. Parazynski, Mission Specialist

Stephen K. Robinson, Mission Specialist

Pedro Duque, Mission Specialist, European Space Agency

Chiaki Mukai, Payload Specialist, Japanese Space Agency

John H. Glenn, Jr., Payload Specialist

 

Orbiter Preparations:

 

Two to Orbiter Processing Facility - June 15, 1998

Rollover to Vehicle Assembly Building - September 14, 1998

Rollout to Launch Pad 39B - September 21, 1998

 

Launch:

 

October 29, 1998 - 2:19:34 p.m. EST. Launch was initially delayed about eight minutes to allow discussion and resolution of a master alarm indication heard during leak checks of cabin pressure following closure of Discovery's hatch. Launch was delayed about an additional 11 minutes due to an aircraft that strayed into the launch danger area.

 

Following ignition of the three main engines, the door covering Discovery's drag chute compartment was torn off, but caused no damage to the Space Shuttle during launch.

 

Landing:

 

November 7, 1998 - 12:04:00 p.m. EST at Runway 33, Kennedy Space Center. Rollout distance was 9,508 feet. Rollout time was 59 seconds. Mission duration was 8 days, 21 hours, 44 minutes. Landing occurred during the 135th orbit. The drag chute was not deployed at landing due to a loss of the drag chute compartment door during launch.

 

Mission Summary:

 

The mission featured the return to space of John Glenn, who flew in space for the first time since becoming the first U.S. astronaut to orbit Earth on February 20, 1962 during mission MA-6.

 

At age 77, Glenn became the oldest human in space. The flight also marked the longest time between space flights for an astronaut, as Glenn was launched on STS-95 exactly 36 years, 8 months, 9 days after completing mission MA-6.

 

Although the participation of Glenn became the central focus of the mission, a plethora of scientific investigations were conducted aboard the pressurized Spacehab laboratory module housed in Discovery's payload bay.

 

About 80 experiments were conducted primarily in the fields of medical and materials science research. A battery of medical tests were performed on astronauts Glenn and Duque to help better understand the effects of weightlessness on balance, perception, immune system response, bone density, muscle density, metabolism, blood circulation and sleep.

 

The crew released and recaptured the Spartan free-flying satellite, which was designed to study solar wind activity to help better understand the potential disruptive effects of solar winds and similar electromagnetic phenomena on electrical and communications systems on Earth.

 

A small satellite called the Petite Amateur Naval Satellite (PANSAT) was released to study methods of more effectively relaying interference-prone low-power radio transmissions from Earth to satellites in space.

 

In addition, the Hubble Space Telescope Orbiting Systems Test (HOST) was flown to test hardware that will be used during the third scheduled Space Shuttle mission to service the Hubble Space Telescope. The International Extreme Ultraviolet Hitchhiker payload was also flown in Discovery's payload bay.
