The '''Bigelow Expandable Activity Module''' ('''BEAM)''') is an experimental [[inflatable space habitat|expandable]] [[International Space Station#Pressurised modules|space station module]] developed by [[Bigelow Aerospace]], under contract towith [[NASA,]]. It was designed for testing as a temporary module on the [[International Space Station]] (ISS) frombeginning 2016in to at least 20202016. ItBEAM arrived at the ISS on April 10, 2016,<ref name="space20160410"/> was [[Docking and berthing of spacecraft|berthed]] to the station on April 16, and was expanded and pressurized on May 28. Originally planned as a two-year test, 2016the module has exceeded expectations and as of 2025, remains in use for additional cargo storage. Following Bigelow Aerospace's suspension of business operations in 2020, ownership of BEAM transferred to NASA.

== History ==

NASA originally considered the idea of inflatable habitats in the 1960s, and developed the [[TransHab]] inflatable module concept in the late 1990s. The TransHab project was canceled by Congress in 2000,<ref name="nasa2000" /><ref name="Sensenbrenner 2000" /><ref name="Abbey 2001" /> and Bigelow Aerospace purchased the rights to the patents developed by NASA to pursue private space station designs.<ref name="Seedhouse 2014" /> In 2006 and 2007, Bigelow launched two demonstration modules to Earth orbit, [[Genesis I]] and [[Genesis II (space habitat)|Genesis II]].<ref name="David 2006" /><ref name="Ledford 2007" />

== Deployment and status ==

[[File:BEAM module expansion series.jpg|thumb|Progression of expansion of BEAM]]

In early 2015, BEAM was scheduled for deployment on the next available ISS transport vehicle, [[SpaceX CRS-8]], which was scheduled for launch in September 2015. Due to a rocket failure during the SpaceX CRS-7 launch in June 2015, the delivery of BEAM was delayed.<ref name="nasasf20150907"/><ref name="launchlog"/> The successful launch of SpaceX CRS-8 took place on April 8, 2016,<ref name="nasasf20160408"/> and the Dragon cargo vehicle was berthed to the nadir port of ''[[Harmony (ISS module)|Harmony]]'' node on April 10.<ref name="unitoday20160411"/> On April 16, British astronaut [[Tim Peake]] extracted BEAM from Dragon's trunk using Canadarm2, and installed it on the aft port of ''[[Tranquility (ISS module)|Tranquility]]'' node.<ref name="sfnow20160416"/>

On June 6, 2016, astronaut [[Jeffrey Williams (astronaut)|Jeff Williams]] and cosmonaut [[Oleg Skripochka]] opened the hatch to BEAM and entered to collect an air sample, download expansion data from sensors, and install monitoring equipment. The hatch to BEAM was re-sealed on June 8, 2016, after three days of tests.<ref name="nasa20160606Huot 2016" /><ref name="nasa20160608Garcia 2016-06-08" /> A second round of tests took place on September 29, of that same year2016, when astronaut [[Kathleen Rubins]] entered the module to install temporary monitoring equipment.<ref name="nasa20160929Garcia 2016-09-26" />

NASA noted in May 2017 that, after spending one year in space, the BEAM instrumentation had recorded "a few probable micrometeoroid debris impacts" but that the module's protective layers had resisted any penetration. Early results from monitors inside the module have shown that [[galactic cosmic radiation]] levels are comparable to those in the rest of the space station. Further testing will try to characterize whether the inflatable structure is any more resilient to radiation than traditional metal modules.<ref name="nasa20170526Mahoney 2017" /><ref name="arstech20170528Berger 2017-05-28" />

In October 2017, it was announced that the module would stay attached to the ISS until 2020, with options for two further one-year extensions. The module will be used to store up to 130 cargo transfer bags in an effort to free upmake additionalavailable space aboard the station.<ref name="arstech20171003Berger 2017-10-03" /> The ISS crew began work in November 2017 to prepare BEAM for use as storage space.<ref name="nasa20171121">{{citeCite web |last=Garcia |first=Mark |date=November 21, 2017 |title=BEAM Work and Vision Checks for Crew Today |url=https://blogs.nasa.gov/spacestation/2017/11/21/beam-work-and-vision-checks-for-crew-today/ |titleaccess-date=BEAMJanuary Work29, and Vision Checks for Crew Today2018 |publisher=NASA}} |first=Mark |last=Garcia |date=November 21, 2017 |accessdate=January 29, 2018{{PD-notice}}</ref>

In July 2019, an engineering assessment certified BEAM's ability to remain attached to the station until 2028, as it has exceeded performance expectations and become a core cargo storage module on the volume-constrained station. A contract extension will be required to allow BEAM to serve its extended operational lifetime.<ref name="Foust 2019" />

At the end of BEAM's mission, it will be removed from the ISS and burn up during reentry.<ref name="ns20130116"/>

With the suspension of all activities at Bigelow Aerospace, development on BEAM has ended. Engineering support passed to Bigelow subcontractor [[ATA Engineering]] in 2022, who will not continue development.<ref name="TMRO-20220126">{{Cite episode |title=SpaceX's Raptor 2 is Revealed! |url=https://www.youtube.com/watch?v=DB4jcVBBOOU |series=TMRO News |date=January 26, 2022 |publisher=TMRO}}</ref>

== Characteristics ==

[[File:ISS-47 BEAM installation (1).jpg|thumb|right|BEAM in the process of being moved to the rearaft port of [[Tranquility (ISS module)|''Tranquility'']] in April 2016]]

BEAM is composed of two metal bulkheads, an aluminum[[aluminium]] structure, and multiple layers of soft fabric with spacing between layers, protecting an internal restraint and bladder system;<ref name="FAQMahoney NASA2015" /> it has neither windows nor internal power.<ref name="airspace201509Lieberman 2015" /> The module was expanded about a month after being attached by its [[Common Berthing Mechanism]] to the space station. It was inflated from its packed dimensions of {{convertcvt|2.16|m|ft|abbr=on}} long and {{convertcvt|2.36|m|ft|abbr=on}} in diameter to its pressurized dimensions of {{convertcvt|4.01|m|ft|abbr=on}} long and {{convertcvt|3.23|m|ft|abbr=on}} in diameter.<ref name="verge20160405Grush 2016" /> The module has a mass of {{convertcvt|3115.1|lb1413|kg|abbr=on|order=flip}},<ref name="nasa-overview" /> and its interior pressure is {{convertcvt|14101.7|psi3|kPa psi atm|1|lk=on|abbr=on|order=out}}, the same as inside of the ISS.<ref name="engadget20160325Seppala 2016" />

BEAM's internal dimensions provide {{convertcvt|565|cuft16.0|m3|0|abbr=on|order=flip}} of volume where a crew member will enter the module three to four times per year to collect sensor data, perform microbial surface sampling, conduct periodic change-out of the radiation area monitors, and inspect the general condition of the module.<ref name="lvrj20130116Robison 2013" /><ref name="FAQMahoney NASA2015" /> The hatch to the module will otherwise remain closed.<ref name="wapo20130116Vastag 2013" /> Its interior is described as being "a large closet with padded white walls", with various equipment and sensors attached to two central supports.<ref name="ap20130117Dreier 2013" />

=== Radiation shielding ===

The flexible Kevlar-like materials of construction are proprietary.<ref name="US 7204460 B2" /><ref name="Lyle2015Lyle 2015" /> The multiple layers of flexible fabric and closed-cell [[Vinyl polymer|vinyl polymer foam]] foam<ref name="Seedhouse2014-26Seedhouse 2014" /> in the BEAM structural shell are expected to provide impact protection (see [[Whipple shield]]) as well as [[Radiation protection#Spacecraft and radiation protection|radiation protection]], but model calculations need to be validated by actual measurements.<ref name="FAQMahoney NASA2015" />

In a 2002 NASA study, it was suggested that materials that have high hydrogen contents, such as [[polyethylene]], can reduce primary and secondary radiation to a greater extent than metals, such as aluminumaluminium.<ref name="nasa-radiation" /> Vinyl polymer may also be used in laboratories and other applications for radiation shield garments.<ref name="newsci20021115Murphy 2002" />

{{asof|2013}}, Bigelow mentioned a concept to build a second BEAM module for use as an [[airlock]] on its planned [[Bigelow Commercial Space Station]]. The module's inflatable nature would provide room for up to three crew or tourists to spacewalk simultaneously, compared with a maximum of two that can operate outside the ISS.<ref name="tpm20130117" />
