Mission highlights

Illustration of the International Space Station after STS-110

The main purpose of STS-110 was to attach the stainless steel S0 Truss segment to the International Space Station (ISS) to the Destiny Laboratory Module. It forms the backbone of the station to which the S1 and P1 truss segments were attached (on the following missions STS-112 and STS-113, respectively).

STS-110 also delivered the Mobile Transporter (MT), which is an 885 kilograms (1,951 lb) (1,950 lb) assembly that glides down rails on the station integrated trusses. The MT was designed and manufactured by Astro Aerospace in Carpinteria, CA. During the next shuttle mission, STS-111, the Mobile Base System (MBS) was mounted to the MT. This Mobile Servicing System (MSS) allows the Canadarm2 to travel down the length of the installed truss structure.

Flight Day 1: Launch

After a launch scrub on 4 April 2002 due to a hydrogen leak, Space Shuttle Atlantis successfully launched on 8 April 2002, from Launch Complex 39B. The countdown on 8 April encountered an unscheduled hold at the T-5 minute mark due to data dropouts in a backup Launch Processing System. The Launch Processing System team reloaded the required data and the countdown resumed. Liftoff occurred with 11 seconds remaining in the launch window.[2]

STS-110 was the first shuttle mission to feature the upgrade Block II main engines, which featured an "improved fuel pump...a stronger integral shaft/disk, and more robust bearings". The intent of the upgrade was to increase the flight capacity of the engines, while increasing reliability and safety.[3]

With the launch of Atlantis, mission specialist Jerry Ross became the first human to have traveled to space seven times.[4]

Expedition 4

Expedition 4 was the fourth expedition to the International Space Station (7 December 2001 - 15 June 2002).

Integrated Truss Structure

The Integrated Truss Structure (ITS) of the International Space Station (ISS) consists of a linear arranged sequence of connected trusses on which various unpressurized components are mounted such as logistics carriers, radiators, solar arrays, and other equipment. It supplies the ISS with a bus architecture. It is approximately 110 meters long and is made from aluminum and stainless steel.

Jerry L. Ross

Jerry Lynn Ross (born January 20, 1948, Crown Point, Indiana) is a retired United States Air Force officer and a former NASA astronaut. He is a veteran of seven Space Shuttle missions, making him the joint record holder for most spaceflights (a record he shares with Franklin Chang-Diaz). His papers, photographs and many personal items are in the Barron Hilton Flight and Space Exploration Archives at Purdue University. He was inducted into the Astronaut Hall of Fame during ceremonies in May 2014.

Ross is the author of Spacewalker: My Journey in Space and Faith as NASA's Record-Setting Frequent Flyer (Purdue University Press, 2013) with John Norberg. In March 2014 it was announced "Spacewalker" will be available in a French translation through the specialist aerospace publisher Altipresse.

Fellow astronaut Chris Hadfield describes Ross in his autobiography, An Astronaut's Guide to Life on Earth, as "the embodiment of the trustworthy, loyal, courteous and brave astronaut archetype."

Lee Morin

Lee Miller Emile Morin (born September 9, 1952) M.D., Ph.D. is a United States Navy Captain and NASA astronaut. He flew on STS-110 in 2002.

List of astronauts by name

This is an alphabetical list of astronauts, people selected to train for a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft.

For a list of everyone who has flown in space, see List of space travelers by name.

More than 560 people have been trained as astronauts. Until recently, astronauts were sponsored and trained exclusively by governments, either by the military or by civilian space agencies. However, with the advent of suborbital flight starting with privately funded SpaceShipOne in 2004, a new category of astronaut was created: the commercial astronaut.

While the term astronaut is sometimes applied to anyone who trains for travels into space—including scientists, politicians, journalists, and tourists—this article lists only professional astronauts, those who have been selected to train professionally. This includes national space programs, industry and commercial space programs which train and/or hire their own professional astronauts.

Names in italic are astronauts who have left Low Earth orbit, names in bold are astronauts who have walked on the moon. The flags indicate the astronaut's primary citizenship during his or her time as an astronaut. The symbol identifies female astronauts.

List of spacewalkers

This is a list of all astronauts who have engaged in an EVA by partly or fully leaving a spacecraft, exclusive of extravehicular activity on the lunar surface. It is ordered chronologically by the date of first spacewalk.

For a list of astronauts who have performed lunar EVA ("moonwalks") see List of Apollo astronauts who walked on the Moon.

The following 11 countries have flown spacewalkers: United States of America 129, Russia (formerly Soviet Union) 63, France 4, Canada, Germany and Japan 3 each, China 2, Italy, Switzerland, Sweden and Great Britain 1 each.

The symbol following a name denotes a female spacewalker.

Michael J. Bloomfield

Michael John "Bloomer" Bloomfield (born March 16, 1959) is an American former astronaut and a veteran of three Space Shuttle missions.

NASA Astronaut Group 14

NASA Astronaut Group 14 ("The Hogs") was a group of 24 astronauts announced by NASA on 5 December 1992. The group's name derived from The Muppet Show skit "Pigs in Space" and from the group's sponsorship of a pot-bellied pig at the Houston Zoo.

NASA Astronaut Group 15

NASA Astronaut Group 15 ("The Flying Escargot") was a group of 23 astronauts selected in 1994. The group name for these astronaut trainees was originally Slugs because no group was convened the previous year and thus the group was slow in arriving. Group members adopted The Flying Escargot as their moniker, possibly in reference to two members of the group being from France, or in reference to the famous "flying escargot" scene in the movie Pretty Woman. The group featured ten pilots, nine mission specialists, and four international mission specialist trainees.

NASA Astronaut Group 16

NASA Astronaut Group 16 ("The Sardines") was a group of 44 astronauts announced by NASA on May 1, 1996. The class was nicknamed "The Sardines" for being such a large class, humorously implying that their training sessions would be as tightly packed as sardines in a can. These 44 candidates compose the largest astronaut class to date. NASA selected so many candidates in preparation for the anticipated need for ISS crew members, along with regular shuttle needs.

NASA Astronaut Group 9

NASA Astronaut Group 9 was a group of 19 astronauts announced on May 29, 1980, and completed their training by 1981. This group was selected to supplement the 35 astronauts that had been selected in 1978, and marked the first time that non-Americans were trained as mission specialists with the selections of ESA astronauts Claude Nicollier and Wubbo Ockels. In keeping with the previous group, astronaut candidates were divided into pilots and mission specialists, with eight pilots, eleven mission specialists, and two international mission specialists within the group.

OTs-20 Gnom

The OTs-20 Gnom ("Gnome") is a Russian revolver manufactured by the KBP Instrument Design Bureau. It uses a proprietary 12.5x40mm STs-110 cartridge developed from a 32 gauge shotgun cartridge. It can fire lead slug (STs-110-04), lead shot (STs-110-02), and armor-piercing steel-core slug (STs-110) cartridges, as well as three types of non-lethal ammunition. The revolver is smooth bore and so it lacks accuracy but has high muzzle velocity and stopping power.

A tactical laser projector is available that mounts on an accessory rail under the ejector rod shroud. It is turned on and off via a pressure switch that can be attached on the grip; the operator just squeezes the grip and the projector goes on or off.

The manufacturer claims that the steel-core slug can penetrate 4.5 mm of "standard body armor plate" at 25 m. They also claim that the dispersion of this bullet at this distance is about 5 cm.

Rex J. Walheim

Rex Joseph Walheim (born October 10, 1962) is a retired United States Air Force officer, engineer and NASA astronaut. He flew three space shuttle missions, STS-110, STS-122, and STS-135. Walheim logged over 566 hours in space, including 36 hours and 23 minutes of spacewalk (EVA) time. He was assigned as mission specialist and flight engineer on STS-135, the final space shuttle mission.


STS-111 was a space shuttle mission to the International Space Station (ISS) flown by Space Shuttle Endeavour. STS-111 resupplied the station and replaced the Expedition 4 crew with the Expedition 5 crew. It was launched on 5 June 2002, from Kennedy Space Center, Florida.

Stephen Frick

Stephen Nathaniel Frick (born September 30, 1964) is an American astronaut and a veteran of two Space Shuttle missions. Raised in Pittsburgh, Pennsylvania, Frick graduated from Pine-Richland High School in 1982, earned a degree in aerospace engineering from the United States Naval Academy in 1986, was commissioned as a United States Navy officer, and trained as a F/A-18 fighter pilot. Stationed aboard the carrier USS Saratoga, he flew combat missions during the Gulf War and then earned a master's degree in aeronautical engineering from the Naval Postgraduate School in 1994.Frick was selected as a NASA astronaut candidate in 1996 and was trained as a Space Shuttle pilot. He piloted mission STS-110, a docking mission with the International Space Station.In July 2006, Frick was assigned to command the crew of STS-122. The 12-day mission delivered the European Space Agency's Columbus laboratory and returned Expedition 16 Flight Engineer Daniel M. Tani to Earth. The mission launched February 7, 2008, and touched down February 20, 2008. NASA announced his retirement in July 2015.

Steven Smith (astronaut)

Steven Lee Smith (born December 30, 1958), is an American technology executive and former NASA astronaut, being a veteran of four space flights covering 16 million miles and seven space walks totaling 49 hours and 25 minutes. Smith’s spacewalk time places him in the top ten on the all-time American and World spacewalk duration lists.
