64-591: As of 2024, current activities at the Houston Spaceport include: The Houston Airport System began initial discussions about establishing a spaceport in Houston in 2011. In 2013, the Houston City Council approved a feasibility study to determine the possibility of obtaining a spaceport launch site operator’s license at Ellington Airport. The results of the study green lit the Houston Spaceport's efforts to become

128-497: A portable life support system . Pressure suits are in general needed at low pressure environments above the Armstrong limit , at around 19,000 m (62,000 ft) above Earth. Space suits augment pressure suits with complex system of equipment and environmental systems designed to keep the wearer comfortable, and to minimize the effort required to bend the limbs, resisting a soft pressure garment's natural tendency to stiffen against

192-455: A 101 kPa (14.6 psi) spacecraft cabin. The joints may get into a restricted or locked position requiring the astronaut to manipulate or program the joint. The NASA Ames Research Center experimental AX-5 hard-shell space suit had a flexibility rating of 95%. The wearer could move into 95% of the positions they could without the suit on. Hybrid suits have hard-shell parts and fabric parts. NASA's Extravehicular Mobility Unit (EMU) uses

256-497: A LCVG, a pressure bladder, a restraint layer, another liner, and a Thermal Micrometeoroid Garment consisting of five aluminized insulation layers and an external layer of white Ortho-Fabric. This space suit is capable of protecting the astronaut from temperatures ranging from −156 °C (−249 °F) to 121 °C (250 °F). During exploration of the Moon or Mars, there will be the potential for lunar or Martian dust to be retained on

320-407: A Space Act Agreement with NASA's Commercial Space Capabilities Office to develop and execute a Human Rating Plan for FFD IVA suit. FFD categorizes their IVA suits according to their mission: Terra for Earth-based testing, Stratos for high altitude flights, and Exos for orbital space flights. Each suit category has different requirements for manufacturing controls, validations, and materials, but are of

384-405: A balloon, even if punctured. The restraint layer is shaped in such a way that bending a joint causes pockets of fabric, called "gores", to open up on the outside of the joint, while folds called "convolutes" fold up on the inside of the joint. The gores make up for the volume lost on the inside of the joint, and keep the suit at a nearly constant volume. However, once the gores are opened all the way,

448-420: A cap worn over the head, which includes earphones and a microphone. Due to the coloration of the version used for Apollo and Skylab , which resembled the coloration of the comic strip character Snoopy , these caps became known as " Snoopy caps ". Generally, to supply enough oxygen for respiration , a space suit using pure oxygen must have a pressure of about 32.4 kPa (240 Torr; 4.7 psi), equal to

512-494: A commercial full IVA space suit, with their first suit completed in 2010. FFD's suits are intended as a light-weight, highly mobile, and inexpensive commercial space suits. Since 2011, FFD has upgraded IVA suit's designs, hardware, processes, and capabilities. FFD has built a total of 7 IVA space suit (2016) assemblies for various institutions and customers since founding, and has conducted high fidelity human testing in simulators, aircraft, microgravity, and hypobaric chambers. FFD has

576-463: A fiberglass Hard Upper Torso (HUT) and fabric limbs. ILC Dover 's I-Suit replaces the HUT with a fabric soft upper torso to save weight, restricting the use of hard components to the joint bearings, helmet, waist seal, and rear entry hatch. Virtually all workable space suit designs incorporate hard components, particularly at interfaces such as the waist seal, bearings, and in the case of rear-entry suits,

640-575: A nitrogen-containing atmosphere. In the US space shuttle, cabin pressure was reduced from normal atmospheric to 70kPa (equivalent to an altitude of about 3000m) for 24 hours before EVA, and after donning the suit, a pre-breathing period of 45 minutes on pure oxygen before decompressing to the EMU working pressure of 30kPa. In the ISS there is no cabin pressure reduction, instead a 4-hour oxygen pre-breathe at normal cabin pressure

704-570: A propulsion test facility and a 3,800 square foot "flame range." In December 2023, Axiom Space opened its Assembly Integration and Test Building on their new 22 acre campus at the Houston Spaceport. The building serves as Axiom's new world headquarters and includes employee offices, astronaut training facilities and mission control, testing labs and a high bay production facility for the construction of space station modules for Axiom Station . The same month, Texas Southern University (TSU) broke ground on their new two-acre aerospace training facility at

768-511: A space suit for astronauts to wear within the Dragon 2 space capsule. Its appearance was jointly designed by Jose Fernandez—a Hollywood costume designer known for his works for superhero and science fiction films —and SpaceX founder and CEO Elon Musk . The first images of the suit were revealed in September 2017. A mannequin, called "Starman" (after David Bowie 's song of the same name ), wore

832-509: A spacesuit for NASA's Artemis III mission. Bio-Suit is a space activity suit under development at the Massachusetts Institute of Technology , which as of 2006 consisted of several lower leg prototypes. Bio-suit is custom fit to each wearer, using laser body scanning. On August 2, 2006, NASA indicated plans to issue a Request for Proposal (RFP) for the design, development, certification, production, and sustaining engineering of

896-466: A specific operating pressure are used from craft that are pressurized to normal atmospheric pressure (such as the Space Shuttle ), this requires astronauts to "pre-breathe" (meaning pre-breathe pure oxygen for a period) before donning their suits and depressurizing in the air lock. This procedure purges the body of dissolved nitrogen, so as to avoid decompression sickness due to rapid depressurization from

960-427: A stove pipe to allow a wide range of movement with the arms and legs. The joints maintain a constant volume of air internally and do not have any counter-force. Therefore, the astronaut does not need to exert to hold the suit in any position. Hard suits can also operate at higher pressures which would eliminate the need for an astronaut to pre-breathe oxygen to use a 34 kPa (4.9 psi) space suit before an EVA from

1024-411: A tight-fitting elastic body suit and a helmet for containing breathing gases , known as a space activity suit (SAS). A space suit should allow its user natural unencumbered movement. Nearly all designs try to maintain a constant volume no matter what movements the wearer makes. This is because mechanical work is needed to change the volume of a constant pressure system. If flexing a joint reduces

1088-401: Is about the alveolar oxygen partial pressure attained at an altitude of 1,860 m (6,100 ft) above sea level. This is about 42% of normal partial pressure of oxygen at sea level, about the same as pressure in a commercial passenger jet aircraft , and is the realistic lower limit for safe ordinary space suit pressurization which allows reasonable capacity for work. When space suits below

1152-429: Is an environmental suit used for protection from the harsh environment of outer space , mainly from its vacuum as a highly specialized pressure suit , but also its temperature extremes, as well as radiation and micrometeoroids . Basic space suits are worn as a safety precaution inside spacecrafts in case of loss of cabin pressure . For extravehicular activity (EVA) more complex space suits are worn, featuring

1216-492: Is more mobile, includes new thermal insulation fabrics , and materials used Falcon ’s interstage and Crew Dragon ’s external unpressurized trunk. On 1 June 2022, NASA announced it had selected competing Axiom Space and Collins Aerospace to develop and provide astronauts with next generation spacesuit and spacewalk systems to first test and later use outside the International Space Station, as well as on

1280-644: Is retained for up to 15 seconds as the effects of oxygen starvation set in. No snap freeze effect occurs because all heat must be lost through thermal radiation or the evaporation of liquids, and the blood does not boil because it remains pressurized within the body, but human flesh expands up to about twice its volume due to ebullism in such conditions, giving the visual effect of a body builder rather than an overfilled balloon. In space, there are highly energized subatomic particles that can cause radiation damage by disrupting essential biological processes. Exposure to radiation can create problems via two methods:

1344-405: Is to form the suit out of multiple layers. The bladder layer is a rubbery, airtight layer much like a balloon. The restraint layer goes outside the bladder, and provides a specific shape for the suit. Since the bladder layer is larger than the restraint layer, the restraint takes all of the stresses caused by the pressure inside the suit. Since the bladder is not under pressure, it will not "pop" like

1408-476: Is used to desaturate nitrogen to an acceptable level. US studies show that a rapid decompression from 101kPa to 55kPa has an acceptable risk, and Russian studies show that direct decompression from 101kPa to 40kPa after 30 minutes of oxygen pre-breathing, roughly the time required for pre-EVA suit checks, is acceptable. The human body can briefly survive the hard vacuum of space unprotected, despite contrary depictions in some popular science fiction . Consciousness

1472-401: Is why many modern space suits do not use 20.7 kPa (160 Torr; 3.0 psi), but 32.4 kPa (240 Torr; 4.7 psi) (this is a slight overcorrection, as alveolar partial pressures at sea level are slightly less than the former). In space suits that use 20.7 kPa, the astronaut gets only 20.7 kPa − 11.6 kPa = 9.1 kPa (68 Torr; 1.3 psi) of oxygen, which

1536-628: Is worn by astronauts involved in Commercial Crew Program missions involving SpaceX. On 4 May 2024, SpaceX unveiled a spacesuit designed for extravehicular activity based on the IVA suit for Polaris Dawn mission in Polaris program . As with the IVA suit, the helmets are 3D-printed , though the EVA helmet incorporates a heads-up display providing information and a camera on suit metrics during operation. It

1600-587: The Apollo missions , life support in space suits was connected to the space capsule via an umbilical cable . However, with the Apollo missions, life support was configured into a removable capsule called the Portable Life Support System that allowed the astronaut to explore the Moon without having to be attached to the space craft. The EMU space suit, used for spacewalks, allows the astronaut to manually control

1664-534: The Constellation Space Suit to meet the needs of the Constellation Program . NASA foresaw a single suit capable of supporting: survivability during launch, entry and abort; zero-gravity EVA; lunar surface EVA; and Mars surface EVA. On June 11, 2008, NASA awarded a US$ 745 million contract to Oceaneering International to create the new space suit. Final Frontier Design (FFD) is developing

1728-636: The Houston City Council approved $ 18.8 million in funding for infrastructure development at the Spaceport. This marked the beginning of a large, multi-phase expansion project. officially known as the "Phase 1 Expansion." The expansion provided infrastructure to 153 acres of the Houston Spaceport property closest to the HASC. This included: streets, water/ wastewater, pipelines , electrical power and communications facilities. The infrastructure development project

Subsequently renamed the Houston Aerospace Support Center (HASC), the building contains clean rooms , laboratories and heavy lift cranes to support vehicle processing and assembly for Houston Spaceport tenants. Purchase of the building marked the functional beginning of the Houston Spaceport, and Intuitive Machines became

1856-776: The NASA Crew Compartment Trainer-2, the EVA Airlock System, the Space Shuttle Motion Base Simulator, a rover and other NASA artifacts. In September 2023, Intuitive Machines moved from the HASC into their newly-constructed $ 40 million Lunar Operations Center (LOC) on 12.5 acres of the Phase 1 Expansion. The LOC covers 125,000 square feet of office and production space for the manufacturing of lunar landers and spacecraft. The center also includes mission control rooms to track and manage lunar missions,

1920-548: The astronaut 's temperature with a Liquid Cooling and Ventilation Garment (LCVG) in contact with the astronaut's skin, from which the heat is dumped into space through an external radiator in the PLSS. Additional requirements for EVA include: As part of astronautical hygiene control (i.e., protecting astronauts from extremes of temperature, radiation, etc.), a space suit is essential for extravehicular activity. The Apollo/Skylab A7L suit included eleven layers in all: an inner liner,

1984-598: The diving suit , rebreather , scuba diving gear, and many others. Many space suit designs are taken from the U.S. Air Force suits, which are designed to work in "high-altitude aircraft pressure[s]", such as the Mercury IVA suit or the Gemini G4C, or the Advanced Crew Escape Suits . The Mercury IVA, the first U.S. space suit design, included lights at the tips of the gloves in order to provide visual aid. As

A public display mock-up of Aouda.X (called Aouda.D) is currently on display at the Dachstein Ice Cave in Obertraun , Austria , after the experiments done there in 2012. In 2024, at the International Astronautical Congress in Milan, Italy, Axiom Space and Prada showed the results of an ongoing collaboration to develop

2112-562: The (then) ninth federally-licensed commercial spaceport in the US. In 2014 the Houston Spaceport signed a letter of intent with the Sierra Nevada Corporation to explore the possibilities of the proposed Houston Spaceport as a potential landing site for SNC's Dreamchaser spacecraft . On June 30, 2015, Houston Airport System was granted a launch site license from the Federal Aviation Administration establishing

2176-550: The 1930s. The first space suit worn by a human in space was the Soviet SK-1 suit worn by Yuri Gagarin in 1961. Since then space suits have been worn beside in Earth orbit, en-route and on the surface of the Moon . A space suit must perform several functions to allow its occupant to work safely and comfortably, inside or outside a spacecraft. It must provide: Advanced suits better regulate

The latter two figures add to 11.6 kPa (87 Torr; 1.7 psi), which

2304-589: The Houston Spaceport as the tenth commercial spaceport in the United States. 400 acres of greenfield space on the northeast corner of Ellington Airport were allocated for spaceport development. In October of the same year, NASA and HAS formally entered a development agreement to provide NASA expertise and training at the Houston Spaceport. The following month, on November 4, 2015, the Houston Spaceport purchased Boeing 's Houston Product Support Center, (an aerospace engineering building used to process payloads for

Stellar Access opened the DISTIL Incubator in the In October 2022, the Houston Spaceport completed a Phase 2 land use plan for the development of the remaining 257 acres of the Spaceport. Phase 2 will include retail and hotels components at the spaceport, as well as expanded infrastructure to accommodate expanded land use by commercial space and education tenants. Additionally, several major infrastructure upgrades are included in Phase 2, including

2496-581: The SpaceX space suit during the maiden launch of the Falcon Heavy in February 2018. For this exhibition launch, the suit was not pressurized and carried no sensors. The suit, which is suitable for vacuum, offers protection against cabin depressurization through a single tether at the astronaut's thigh that feeds air and electronic connections. The helmets, which are 3D-printed, contain microphones and speakers. As

Related preceding technologies include the stratonautical space suit , the gas mask used in World War II , the oxygen mask used by pilots of high-flying bombers in World War II, the high-altitude or vacuum suit required by pilots of the Lockheed U-2 and SR-71 Blackbird ,

2624-410: The back hatch, where all-soft alternatives are not viable. Skintight suits, also known as mechanical counterpressure suits or space activity suits, are a proposed design which would use a heavy elastic body stocking to compress the body. The head is in a pressurized helmet, but the rest of the body is pressurized only by the elastic effect of the suit. This mitigates the constant volume problem, reduces

2688-402: The conditions in which they will be used. The vacuum environment of space has no pressure, so gases will expand and exposed liquids may evaporate. Some solids may sublimate . It is necessary to wear a suit that provides sufficient internal body pressure in space. The most immediate hazard is in attempting to hold one's breath during explosive decompression as the expansion of gas can damage

2816-504: The feasibility of printing rigid suit elements, bearing races, ball bearings, seals, and sealing surfaces. There are certain difficulties in designing a dexterous space suit glove and there are limitations to the current designs. For this reason, the Centennial Astronaut Glove Challenge was created to build a better glove. Competitions have been held in 2007 and 2009, and another is planned. The 2009 contest required

2880-484: The glove to be covered with a micro-meteorite layer. Since 2009, the Austrian Space Forum has been developing "Aouda.X", an experimental Mars analogue space suit focusing on an advanced human–machine interface and on-board computing network to increase situational awareness . The suit is designed to study contamination vectors in planetary exploration analogue environments and create limitations depending on

2944-494: The gloves. EMU gloves, which are used for spacewalks, are heated to keep the astronaut's hands warm. The Phase VI gloves, meant for use with the Mark III suit , are the first gloves to be designed with "laser scanning technology, 3D computer modeling, stereo lithography, laser cutting technology and CNC machining". This allows for cheaper, more accurate production, as well as increased detail in joint mobility and flexibility. Prior to

3008-435: The initial and final volume of the joint, P is the pressure in the suit, and W is the resultant work. It is generally true that all suits are more mobile at lower pressures. However, because a minimum internal pressure is dictated by life support requirements, the only means of further reducing work is to minimize the change in volume. All space suit designs try to minimize or eliminate this problem. The most common solution

3072-519: The internal environment of the suit. The Mark III suit has a backpack containing about 12 pounds of liquid air for breathing, pressurization, and heat exchange. The development of the spheroidal dome helmet was key in balancing the need for field of view, pressure compensation, and low weight. One inconvenience with some space suits is the head being fixed facing forwards and being unable to turn to look sideways. Astronauts call this effect "alligator head". In February 2015, SpaceX began developing

3136-959: The joint cannot be bent any further without a considerable amount of work. In some Russian space suits, strips of cloth were wrapped tightly around the cosmonaut 's arms and legs outside the space suit to stop the space suit from ballooning when in space. The outermost layer of a space suit, the Thermal Micrometeoroid Garment, provides thermal insulation, protection from micrometeoroids, and shielding from harmful solar radiation . There are four main conceptual approaches to suit design: Soft suits typically are made mostly of fabrics. All soft suits have some hard parts; some even have hard joint bearings. Intra-vehicular activity and early EVA suits were soft suits. Hard-shell suits are usually made of metal or composite materials and do not use fabric for joints. Hard suits joints use ball bearings and wedge-ring segments similar to an adjustable elbow of

3200-416: The lunar surface for the crewed Artemis missions , and prepare for human missions to Mars. Several companies and universities are developing technologies and prototypes which represent improvements over current space suits. 3D printing (additive manufacturing) can be used to reduce the mass of hard-shell space suits while retaining the high mobility they provide. This fabrication method also allows for

3264-419: The lungs by overexpansion rupture. These effects have been confirmed through various accidents (including in very-high-altitude conditions, outer space and training vacuum chambers ). Human skin does not need to be protected from vacuum and is gas-tight by itself. It only needs to be mechanically restrained to retain its normal shape and the internal tissues to retain their volume. This can be accomplished with

3328-500: The need for extravehicular activity grew, suits such as the Apollo A7L included gloves made of a metal fabric called Chromel-r in order to prevent punctures. In order to retain a better sense of touch for the astronauts, the fingertips of the gloves were made of silicone. With the shuttle program, it became necessary to be able to operate spacecraft modules, so the ACES suits featured gripping on

3392-511: The particles can react with water in the human body to produce free radicals that break DNA molecules apart, or by directly breaking the DNA molecules. Temperature in space can vary extremely depending on the exposure to radiant energy sources. Temperatures from solar radiation can reach up to 250 °F (121 °C), and in its absence, down to −387 °F (−233 °C). Because of this, space suits must provide sufficient insulation and cooling for

3456-438: The possibility of a space suit depressurization and gives a very lightweight suit. When not worn, the elastic garments may appear to be that of clothing for a small child. These suits may be very difficult to put on and face problems with providing a uniform pressure. Most proposals use the body's natural perspiration to keep cool. Sweat evaporates readily in vacuum and may desublime or deposit on objects nearby: optics, sensors,

3520-579: The potential for in-situ fabrication and repair of suits, a capability which is not currently available, but will likely be necessary for Martian exploration. The University of Maryland began development of a prototype 3D printed hard suit in 2016, based on the kinematics of the AX-5 . The prototype arm segment is designed to be evaluated in the Space Systems Laboratory glovebox to compare mobility to traditional soft suits. Initial research has focused on

3584-616: The pressure regime chosen for a simulation. Since 2012, for the Mars2013 analogue mission by the Austrian Space Forum to Erfoud , Morocco , the Aouda.X analogue space suit has a sister in the form of Aouda.S. This is a slightly less sophisticated suit meant primarily to assist Aouda.X operations and be able to study the interactions between two (analogue) astronauts in similar suits. The Aouda.X and Aouda.S space suits have been named after

3648-503: The space suit. When the space suit is removed on return to the spacecraft, there will be the potential for the dust to contaminate surfaces and increase the risks of inhalation and skin exposure. Astronautical hygienists are testing materials with reduced dust retention times and the potential to control the dust exposure risks during planetary exploration. Novel ingress and egress approaches, such as suitports , are being explored as well. In NASA space suits, communications are provided via

3712-608: The spacecraft, such as the Gemini G4C suit. They include more protection from the harsh conditions of space, such as protection from micrometeoroids and extreme temperature change. EVA suits, such as the EMU , are used outside spacecraft, for either planetary exploration or spacewalks. They must protect the wearer against all conditions of space, as well as provide mobility and functionality. The first full-pressure suits for use at extreme altitudes were designed by individual inventors as early as

3776-455: The spaceport's first commercial tenant when they moved into the HASC in August, 2016. In 2018, HAS constructed a $ 12.4 million air traffic control tower EFD with a dedicated mission control for the Houston Spaceport's commercial spaceflight activities. The 143-ft tower replaced the original tower, which was built in 1955 and suffered extensive damage during Hurricane Ike . On October 17, 2018,

Also in 2021, Venus Aerospace relocated from Silicon Valley to a 30,000 square foot headquarters at the Houston Spaceport in order to develop their hypersonic Stargazer spacecraft and perform engine testing. Another aerospace company, RAVN Aerospace , relocated their headquarters to

3904-551: The suits need the tether connection and do not offer protection against radiation, they are not used for extra-vehicular activities. The suits are custom-made for each astronaut. In 2018, NASA commercial crew astronauts Bob Behnken , and Doug Hurley tested the spacesuit inside the Dragon 2 spacecraft in order to familiarize themselves with the suit. They wore it in the Crew Dragon Demo-2 flight launched on 30 May 2020. The suit

Three types of space suits exist for different purposes: IVA (intravehicular activity), EVA (extravehicular activity), and IEVA (intra/extravehicular activity). IVA suits are meant to be worn inside a pressurized spacecraft, and are therefore lighter and more comfortable. IEVA suits are meant for use inside and outside
