NASA astronauts Jerry Ross and Jim Newman conducted the first-ever spacewalk from the International Space Station during the STS-88 mission. The historic 7-hour and 21-minute EVA helped install Unity Node 1, connecting it to the Russian Zarya module.
The International Space Station (ISS) stands as humanity's most ambitious space endeavor yet with spacewalks playing a crucial role in its maintenance and expansion. While spacewalks had been conducted since the 1960s the first-ever ISS spacewalk marked a new chapter in space exploration.
On December 7 1998 NASA astronauts Jerry Ross and Jim Newman made history by conducting the first spacewalk from the ISS during the STS-88 mission. This groundbreaking 7-hour and 21-minute excursion helped install the first American component Unity Node 1 to the already orbiting Russian Zarya module setting the foundation for what would become humanity's permanent home in space.
The International Space Station's Early Days
#The International Space Station's construction began in 1998 with the launch of its first component, the Russian Zarya module. This marked the start of an ambitious international collaboration that would create humanity's largest structure in space.
ISS Construction and Assembly
#The assembly of the ISS commenced when the Russian Zarya Control Module launched on November 20, 1998. Two weeks later, Space Shuttle Endeavour delivered the Unity Node-1 module, connecting it to Zarya through a series of spacewalks. Here's a breakdown of the initial assembly phases:
| Module | Launch Date | Country |
|---|---|---|
| Zarya | Nov 20, 1998 | Russia |
| Unity (Node 1) | Dec 4, 1998 | USA |
| Zvezda | Jul 12, 2000 | Russia |
Preparing for the First Spacewalk
#The preparation for the first ISS spacewalk involved meticulous planning over several months. NASA astronauts trained in the Neutral Buoyancy Laboratory, a massive pool that simulated zero-gravity conditions. The spacewalk equipment included:
- EMU spacesuits modified for ISS operations
- Tethers rated for specific loads
- Battery-powered life support systems
- Communication systems integrated with ISS networks
The Russian Zvezda module's addition in 2000 created the foundation for permanent human occupation. Expedition 1 Commander William Shepherd joined Russian cosmonauts Yuri Gidzenko aboard the station two months later, establishing continuous human presence in space.
The Historic First ISS Spacewalk
#The first ISS-based extravehicular activity (EVA) occurred on March 11, 2001, marking a significant milestone in space station operations. This spacewalk differed from previous assembly EVAs as it was conducted by ISS Expedition 2 crew members rather than Space Shuttle astronauts.
Mission STS-104 Details
#The spacewalk took place during Expedition 2, lasting 8 hours 56 minutes. The primary objective focused on preparing the Destiny laboratory module for the installation of the Quest Airlock. During the EVA, the crew relocated a Pressurized Mating Adapter connecting the Unity node to the Destiny laboratory module.

Astronauts Susan Helms and Jim Voss
#Susan Helms became the first woman to conduct an EVA from the ISS alongside crewmate Jim Voss. The duo:
- Connected power cables between the Destiny module the station's electrical system
- Installed a rigid tether between Unity Node PMA-1
- Removed a Lab Cradle Assembly from Destiny's exterior
- Positioned several vital components for future spacewalks
Both astronauts completed their tasks using the Russian Orlan spacesuits launched with the station's early modules. Their successful EVA established procedures for future station-based spacewalks conducted by long-duration crew members.
Equipment and Safety Protocols
#Spacewalks from the International Space Station require specialized equipment and rigorous safety measures to protect astronauts in the harsh environment of space. Each EVA follows strict protocols developed through years of spaceflight experience.
Space Suits and Tools
#The ISS maintains two types of spacesuits: the Russian Orlan and American Extravehicular Mobility Unit (EMU). Each suit provides:
- Life support systems that regulate temperature oxygen supply for 6-8 hours
- Communications equipment integrated into the helmet for constant contact
- Built-in propulsion units for emergency self-rescue scenarios
- Tool carriers with specialized equipment for specific EVA tasks
Standard EVA tools include:
- Pistol grip tools for tightening bolts torqueing mechanisms
- Safety tethers connecting astronauts to the station
- Portable work lights for operations in darkness
- HD cameras mounted on helmets for documentation monitoring
Safety Procedures During EVAs
#- Pre-breathe protocol requiring 4 hours of pure oxygen to prevent decompression sickness
- Buddy system pairing two spacewalkers for mutual assistance
- Continuous monitoring by Mission Control ground crew
- Multiple tether points securing astronauts to the station
- Emergency rescue procedures using SAFER jetpack units
- Regular suit pressure equipment checks at 15-minute intervals
| Safety Equipment | Purpose | Check Frequency |
|---|---|---|
| Primary Tether | Physical connection to ISS | Every 30 minutes |
| SAFER Unit | Emergency propulsion | Pre-EVA checkout |
| Suit Pressure | Life support integrity | Every 15 minutes |
| Communication System | Mission control contact | Continuous |
Key Achievements During the First Spacewalk
#The first spacewalk from the ISS accomplished several critical milestones in space station assembly. The EVA demonstrated the capability to perform complex construction tasks in orbit while establishing protocols for future spacewalks.
Quest Airlock Installation
#The spacewalk prepared the groundwork for installing the Quest Airlock, a vital component for future ISS operations. The crew connected power cables through the Destiny module's framework to create the electrical infrastructure needed for the airlock. They installed handrails, communication cables, secured mounting brackets to the port side of the Unity node where Quest would later dock.
Mission Objectives and Success
#The 8-hour 56-minute EVA met all primary objectives in preparing the Destiny laboratory module. The crew:
- Relocated Pressurized Mating Adapter-3 to its new position
- Installed 6 power cable connections between modules
- Configured 4 cooling system lines for future expansion
- Set up 3 external communication antennas
- Tested 2 safety tether points for upcoming spacewalks
