SpaceX CRS-11

<h2 id="rocket-and-spacecraft">Rocket and spacecraft</h2>

The CRS-11 mission was the first time that a Dragon spacecraft has been reused, helping SpaceX to scale back its production line and shift focus to <a href="/facts/SpaceX_Dragon_2/Wy8kUegK">Dragon 2</a>.<a class="footnote-ref" id="fnref:1" href="#fn:1">1</a>
CRS-11 launched aboard a Falcon 9 launch vehicle on 3 June 2017 at 21:07:38 <a href="/facts/Coordinated_Universal_Time/2EnjfSyu">UTC</a> from <a href="/facts/Kennedy_Space_Center/zmwszuPr">Kennedy Space Center</a>'s <a href="/facts/Kennedy_Space_Center_Launch_Complex_39A/pnH83f5s">Launch Complex 39A</a> (LC-39A).<a class="footnote-ref" id="fnref:2" href="#fn:2">2</a> The spacecraft rendezvoused with the station on 5 June 2017 and conducted a series of orbit adjustment burns to match speed, altitude, and orientation with the ISS. After arriving at the capture point at 13:37 UTC, the vehicle was snared at 13:52 UTC by the <a href="/facts/Mobile_Servicing_System/Sj8HSaJv">Canadarm2</a>, operated by <a href="/facts/Peggy_Whitson/TwjHpJTP">Peggy Whitson</a> and <a href="/facts/Jack_Fischer/oL45HcPl">Jack Fischer</a>.<a class="footnote-ref" id="fnref:3" href="#fn:3">3</a> It was berthed to the <a href="/facts/Harmony_(ISS_module)/RY1kewMY">Harmony</a> module at 16:07 UTC.<a class="footnote-ref" id="fnref:4" href="#fn:4">4</a>
The Falcon 9 first stage landed successfully on <a href="/facts/Landing_Zone_1/cEoRJoJ3">Landing Zone 1</a>, making it the fifth successful touch down on land and the 11th overall.<a class="footnote-ref" id="fnref:5" href="#fn:5">5</a>
The CRS-11 Dragon remained attached to the ISS for just over 27 days. Having been filled with around 2,708 kg (5,970 lb) of cargo,<a class="footnote-ref" id="fnref:6" href="#fn:6">6</a> Dragon was unberthed from the station on 2 July 2017 at approximately 18:00 UTC.<a class="footnote-ref" id="fnref:7" href="#fn:7">7</a> It was moved to its release position by Canadarm2, but poor sea conditions forced a delay to the following day.<a class="footnote-ref" id="fnref:8" href="#fn:8">8</a> On 3 July 2017, at 06:41 UTC, crew members commanded Canadarm2 to release Dragon, and soon after the spacecraft began a series of thruster firings to move it away from the station.<a class="footnote-ref" id="fnref:9" href="#fn:9">9</a> About five hours after departing from ISS, Dragon closed its <a href="/facts/Guidance%2c_navigation%2c_and_control/Terngs4t">guidance, navigation, and control</a> (GNC) bay door and conducted a 10-minute deorbit burn. Immediately after, the spacecraft jettisoned its cargo trunk and oriented itself for reentry. Dragon splashed down in the Pacific Ocean off <a href="/facts/Baja_California/vJY3AFwn">Baja California</a> at 12:12 UTC.<a class="footnote-ref" id="fnref:10" href="#fn:10">10</a>

<h2 id="payload">Payload</h2>
NASA has contracted for the CRS-11 mission from SpaceX and therefore determines the primary payload, date/time of launch, and <a href="/facts/Orbital_elements/QCG5SI6o">orbital parameters</a> for the Dragon <a href="/facts/Space_capsule/wd4mpTCX">space capsule</a>. CRS-11 carried a total of 2,708 kg (5,970 lb) of material into orbit. This included 1,665 kg (3,671 lb) of pressurised cargo with packaging bound for the International Space Station, and 1,002 kg (2,209 lb) of unpressurised cargo composed of three external station experiments: <a href="/facts/Neutron_Star_Interior_Composition_Explorer/Azh7WebU">Neutron Star Interior Composition Explorer</a> (NICER), MUSES and <a href="/facts/Roll_Out_Solar_Array/HnlVScTR">Roll Out Solar Array</a> (ROSA).<a class="footnote-ref" id="fnref:11" href="#fn:11">11</a><a class="footnote-ref" id="fnref:12" href="#fn:12">12</a>
The following is a breakdown of cargo bound for the ISS:<a class="footnote-ref" id="fnref:13" href="#fn:13">13</a>

<ul><li>Science investigations: 1,069 kg (2,357 lb)
<ul><li>Advanced Plant Habitat (APH) - a NASA- and <a href="/facts/Sierra_Nevada_Corporation/e1HRGsMP">ORBITEC</a>-developed payload built in <a href="/facts/Madison%2c_Wisconsin/jcVnNquB">Madison, Wisconsin</a>. APH is a fully automated facility that is used to conduct plant bioscience research on the ISS.<a class="footnote-ref" id="fnref:14" href="#fn:14">14</a><a class="footnote-ref" id="fnref:15" href="#fn:15">15</a></li></ul></li>
<li>Crew supplies: 242 kg (534 lb)</li>
<li>Vehicle hardware: 199 kg (439 lb)</li>
<li>Spacewalk equipment: 56 kg (123 lb)</li>
<li>Computer resources: 27 kg (60 lb)</li>
<li>External payloads:
<ul><li><a href="/facts/Roll_Out_Solar_Array/HnlVScTR">Roll Out Solar Array</a> (ROSA): 325 kg (717 lb)</li>
<li><a href="/facts/Neutron_Star_Interior_Composition_Explorer/Azh7WebU">Neutron Star Interior Composition Explorer</a> (NICER): 372 kg (820 lb)</li>
<li>Multiple User System for Earth Sensing (MUSES): 305 kg (672 lb)</li></ul></li></ul>
A constellation of five <a href="/facts/CubeSat/jL2IpYKd">CubeSats</a> was also carried on the mission as part of <a href="/facts/Birds-1/1ULGAJV1">Birds-1</a>, one each from the countries of <a href="/facts/Japan/U5mz0SRT">Japan</a>, <a href="/facts/Nigeria/gbW17BX8">Nigeria</a>, <a href="/facts/Bangladesh/NXk4f78Y">Bangladesh</a>, <a href="/facts/Ghana/IkUw32Ya">Ghana</a>, and <a href="/facts/Mongolia/ogQzUcQb">Mongolia</a>. The satellites from Bangladesh (<a href="/facts/BRAC_ONNESHA/07Hd064j">BRAC ONNESHA</a>), Ghana (<a href="/facts/GhanaSat-1/8nAkDIJk">GhanaSat-1</a>), and Mongolia (<a href="/facts/Mazaalai_(satellite)/XgkdpssC">Mazaalai</a>) were those countries' first satellites in space.<a class="footnote-ref" id="fnref:16" href="#fn:16">16</a>
