NG-11
NG-11, previously known as OA-11, is the twelfth flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its eleventh flight to the International Space Station under the Commercial Resupply Services (CRS-1) contract with NASA. The mission launched on 17 April 2019 at 20:46:07 UTC. This is the last mission from the extended CRS-1 (phase 1) contract; follow-up missions are part of the CRS-2 contract. Cygnus NG-11 was also the first mission to load critical hardware onto Cygnus within the last 24 hours prior to launch, a new Antares feature. Orbital ATK and NASA jointly developed a new space transportation system to provide commercial cargo resupply services to the International Space Station (ISS). Under the Commercial Orbital Transportation System (COTS) program, then Orbital Sciences designed and built Antares, a medium-class launch vehicle; Cygnus, an advanced maneuvering spacecraft, and a Pressurized Cargo Module which is provided by Orbital's indust ...

Cygnus (spacecraft)
Cygnus is an expendable American cargo spacecraft developed by Orbital Sciences Corporation and now manufactured and launched by Northrop Grumman Space Systems as part of NASA's Commercial Resupply Services (CRS) program. It is launched by Northrop Grumman's Antares rocket or ULA's Atlas V and is designed to transport supplies to the International Space Station (ISS) following the retirement of the American Space Shuttle. Since August 2000, ISS resupply missions have been regularly flown by the Russian Progress spacecraft, as well as by the European Automated Transfer Vehicle, and the Japanese H-II Transfer Vehicle. With the Cygnus spacecraft and the SpaceX Dragon, NASA seeks to increase its partnerships with domestic commercial aviation and aeronautics industry. ''Cygnus'' is the Latinized Greek word for swan and a northern constellation. Development With Rocketplane Kistler unable to meet funding obligations for its K-1 launch vehicle under the terms of the COTS agre ...

Commercial Resupply Services
Commercial Resupply Services (CRS) are a series of flights awarded by NASA for the delivery of cargo and supplies to the International Space Station (ISS) on commercially operated spacecraft. The first CRS contracts were signed in 2008 and awarded $1.6 billion to SpaceX for twelve cargo Dragon and $1.9 billion to Orbital Sciences for eight Cygnus flights, covering deliveries to 2016. The Falcon 9 and Antares rockets were also developed under the CRS program to deliver cargo spacecraft to the ISS. The first operational resupply missions were flown by SpaceX in 2012 ( SpaceX CRS-1) and Orbital Sciences in 2014 ( Cygnus CRS Orb-1). A second phase of contracts (known as CRS-2) was solicited in 2014. In 2015, NASA extended CRS-1 to twenty flights for SpaceX and twelve flights for Orbital ATK. CRS-2 contracts were awarded in January 2016 to Orbital ATK Cygnus, Sierra Nevada Corporation Dream Chaser, and SpaceX Dragon 2, for cargo transport flights beginning in 2019 and expected to ...

SpaceX CRS-17
SpaceX CRS-17, also known as SpX-17, was a Commercial Resupply Services mission (CRS) to the International Space Station that was launched aboard a Falcon 9 rocket on 4 May 2019. The mission was contracted by NASA and was flown by SpaceX. Launch schedule history In February 2016, it was announced that NASA had awarded a contract extension to SpaceX for five additional CRS missions ( CRS-16 to CRS-20). In June 2016, a NASA Inspector General report had this mission manifested for October 2018, but by January 2019 this had been pushed back to April 2019. Due to a Dragon 2 test anomaly on 20 April 2019, SpaceX needed to acquire a permit to allow landing on the drone ship, "Of Course I Still Love You". The ship was stationed just downrange "to ensure the integrity of the area and preserve valuable information". Primary payload Total weight of the cargo on the CRS-17 mission was , consisting of in the pressurized section and 965 kg in the unpressurized section. Cargo in ...

SpaceX CRS-16
SpaceX CRS-16, also known as SpX-16, was a Commercial Resupply Service mission to the International Space Station launched on 5 December 2018 aboard a Falcon 9 launch vehicle. The mission was contracted by NASA and is flown by SpaceX. This CRS mission is the first with the Falcon 9 Block 5. It carried the Global Ecosystem Dynamics Investigation (GEDI) lidar and the Robotic Refueling Mission 3 (RRM3) experiment as external payloads. Launch In February 2016, it was announced that NASA had awarded a contract extension to SpaceX for five additional CRS missions (CRS-16 to CRS-20). , a NASA Inspector General report had this mission manifested for August 2018, but it was later delayed to 29 November 2018, 4 December 2018, and 5 December 2018. The first stage booster B1050.1 experienced a grid fin hydraulic pump stall on re-entry. This caused the first stage to go into a roll after the re-entry burn.

Unity (ISS Module)
upright=1.0, The ''Unity'' module as seen in May 2011 The ''Unity'' connecting module, also known as Node 1, is the first U.S.-built component of the International Space Station (ISS). It connects the Russian and United States segments of the station, and is where crew eat meals together. The module is cylindrical in shape, with six berthing locations ( forward, aft, port, starboard, zenith, and nadir) facilitating connections to other modules. ''Unity'' measures in diameter, is long, made of steel, and was built for NASA by Boeing in a manufacturing facility at the Marshall Space Flight Center in Huntsville, Alabama. ''Unity'' is the first of the three connecting modules; the other two are ''Harmony'' and '' Tranquility''. Launch and initial berthing ''Unity'' (with its two attached PMAs) was carried into orbit as the primary cargo of the Space Shuttle ''Endeavour'' (OV 105) on STS-88, the first Space Shuttle mission dedicated to assembly of the station.

Antares (rocket)
Development The NASA COTS award was for and Orbital Sciences expected to invest an additional $150 million, split between $130 million for the booster and $20 million for the spacecraft. A Commercial Resupply Service contract of $1.9 billion for eight flights was awarded in 2008. As of April 2012, development costs were estimated at $472 million. In June 2008, it was announced that the Mid-Atlantic Regional Spaceport, formerly part of the Wallops Flight Facility, in Virginia, would be the primary launch site for the rocket. Launch pad 0A (LP-0A), previously used for the failed Conestoga rocket, would be modified to handle Antares. Wallops allows launches which reach the International Space Station's orbit as effectively as those from Cape Canaveral, Florida, while being less crowded. The first Antares flight launched a Cygnus mass simulator. On December 10, 2009, Alliant Techsystems Inc. (ATK) test-fired their Castor 30 motor for use on the second stage of the Anta ...

Mid-Atlantic Regional Spaceport
The Mid-Atlantic Regional Spaceport (MARS) is a commercial space launch facility located at the southern tip of NASA's Wallops Flight Facility on Wallops Island in Virginia, just east of the Delmarva Peninsula and south of Chincoteague, Virginia, United States. It is owned and operated by the Virginia Commercial Space Flight Authority. Background The Virginia General Assembly created the political subdivision Virginia Commercial Space Flight Authority (VCSFA), also known as Virginia Space, in 1995 to promote the development of the commercial space flight industry, economic development, aerospace research, and Science, Technology, Engineering, and Math (STEM) education throughout the Commonwealth. This initiative was done from the recommendations of the Batten College at Old Dominion University, with Dr. Billie Reed, a longtime professor at the University, installed as its Executive Director. In 1997, Virginia Space entered into a Reimbursable Space Act Agreement with NAS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raavana 1
Raavana-1 was the first Sri Lankan satellite. The CubeSat-sized satellite was launched as part of the Cygnus NG-11 mission to the ISS on 17 April 2019. On 17 June 2019, the satellite was deployed into orbit from the ISS. Development The research satellite was developed by Tharindu Dayarathna and Dulani Chamika Vithanage, scholars of Peradeniya University's Engineering Faculty and Asian Institute of Technology. The satellite was designed in Japan. It had a volume of about 1000 cubic centimetre and a mass of about 1.1 kg. The lifespan of the satellite was about one and half years. The satellite took images of Sri Lanka and other countries near Sri Lanka. It used magnetic torquers to reduce its angular velocity.
