Cygnus 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 industrial par ...

Dragon C108
SpaceX Dragon C108 is a Cargo Dragon space capsule built by SpaceX. It is the first Dragon capsule to be flown three times, having its third launch in 2019. C108 was first used on CRS-6, and then used again for the CRS-13 and CRS-18 missions. It was the first capsule to be used a third flight, marking a milestone in SpaceX's drive to reduce space launch costs through reusing hardware. History C108 was built as the eighth production Dragon capsule. This new Dragon was launched on the CRS-6 mission to the International Space Station (ISS). It splashed down on May 21, 2015 and was successfully retrieved. To prepare for its second flight, it had its heatshield replaced while the hull, avionics Avionics (a blend of ''aviation'' and ''electronics'') are the electronic systems used on aircraft. Avionic systems include communications, navigation, the display and management of multiple systems, and the hundreds of systems that are fitt ..., and Draco thrusters were refurbi ...

Dulles, Virginia
Dulles () is an unincorporated area in Loudoun County, Virginia, United States, and is part of the Washington metropolitan area. The headquarters of Northrop Grumman Innovation Systems and ODIN Technologies, as well as the former headquarters of MCI Inc. and AOL are located in Dulles. The National Weather Service Baltimore/Washington forecast office and the National Weather Service's Sterling Field Support Center are also both in Dulles. Geography Dulles covers roughly the southwestern third of Sterling, Virginia (another unincorporated community). The usage of Dulles as a community name began in the mid-1980s when Loudoun County economic development officer Pam Treadwell successfully lobbied the United States Postal Service to allow Sterling businesses and residents to use Dulles as an alternative address. The USPS defines Dulles as an "acceptable" city name for the 20166 ZIP code, whose "recommended" city name is Sterling. Dulles is also the city name for ZIP code 20189. The ...

Wallops Flight Facility
Wallops Flight Facility (WFF) is a rocket launch site on Wallops Island on the Eastern Shore of Virginia, United States, just east of the Delmarva Peninsula and approximately north-northeast of Norfolk. The facility is operated by the Goddard Space Flight Center in Greenbelt, Maryland, and primarily serves to support science and exploration missions for NASA and other Federal agencies. WFF includes an extensively instrumented range to support launches of more than a dozen types of sounding rockets; small expendable suborbital and orbital rockets; high-altitude balloon flights carrying scientific instruments for atmospheric and astronomical research; and, using its Research Airport, flight tests of aeronautical research aircraft, including unmanned aerial vehicles. There have been over 16,000 launches from the rocket testing range at Wallops since its founding in 1945 in the quest for information on the flight characteristics of airplanes, launch vehicles, and spacecraft, an ...

Commercial Resupply Services 2
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 ...

Antares NG-11 Launch
Antares is the brightest star in the constellation of Scorpius. It has the Bayer designation α Scorpii, which is Latinised to Alpha Scorpii. Often referred to as "the heart of the scorpion", Antares is flanked by σ Scorpii and τ Scorpii near the center of the constellation. Distinctly reddish when viewed with the naked eye, Antares is a slow irregular variable star that ranges in brightness from an apparent visual magnitude of +0.6 down to +1.6. It is on average the fifteenth-brightest star in the night sky. Classified as spectral type M1.5Iab-Ib, Antares is a red supergiant, a large evolved massive star and one of the largest stars visible to the naked eye. Its exact size remains uncertain, but if placed at the center of the Solar System, it would reach to somewhere between the orbits of Mars and Jupiter. Its mass is calculated to be around 12 times that of the Sun. Antares is the brightest and most evolved stellar member of the nearest OB association, the Sc ...

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. Origin of the name When naming the country's first satellite, Sanath Panaavanna, Director General and Engineer at the Center for New Technology - Arthur C. Clarke Institute of Sri Lanka, along with his two engineering students wanted to put forward an authentic n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NepaliSat-1
NepaliSat-1, also known as Bird NPL, was a Nepalese low orbit research satellite and the first satellite of Nepal. Along with a Sri Lankan satellite, Raavana 1, it was launched as part of Cygnus NG-11 by the United States on 17 April 2019. It reached the International Space Station on 19 April 2019, to be deployed later, and was estimated to revolve the Earth for six months. Background The nanosatellite was developed by two Nepalese scientists Aabhas Maskey and Hariram Shrestha , both of whom were at the time studying at Japanese Kyushu Institute of Technology. Aabhas Maskey, a PhD candidate in space engineering was the project manager of the Birds-3 project and he involved himself in this project.

Commercial Orbital Transportation Services
Commercial Orbital Transportation Services (COTS) was a NASA program to coordinate the development of vehicles for the delivery of crew and cargo to the International Space Station by private companies. The program was announced on January 18, 2006 and successfully flew all cargo demonstration flights by September 2013, when the program ended. NASA's Final Report on the Commercial Orbital Transportation Services program considers it an unqualified success and a model for future public-private collaboration. Compared to traditional cost-plus contracts employed by NASA, such as the $12 billion Orion (spacecraft) contract, the unprecedented efficiency of the $800 million COTS investment resulted in "two new U.S. medium-class launch vehicles and two automated cargo spacecraft". NASA signed COTS agreements with SpaceX and Rocketplane Kistler (RpK) in 2006, but later terminated the agreement with RpK due to insufficient private funding. NASA then signed an agreement with Orbital Scien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
