ЦитироватьRocket Lab to launch dedicated Electron mission for DARPARocket Lab to launch dedicated Electron mission for DARPAThe mission intends to space-qualify a new membrane reflect-array antenna and highlights the Electron rocket's suitability as a responsive, flexible and rapidly-acquired launch service for commercial and government missions alikeHuntington Beach, California. January 22, 2019 – Small satellite launch company Rocket Lab announced today that its first mission of 2019 will be a dedicated launch of a 150kg satellite for the Defense Advanced Research Projects Agency (DARPA). The mission highlights US Government demand for the type of responsive, ultra-flexible and rapidly acquired launch service that characterizes the Rocket Lab launch experience on Electron.DARPA's Radio Frequency Risk Reduction Deployment Demonstration (R3D2) mission is scheduled for launch in late February and intends to space-qualify a prototype reflect array antenna to improve radio communications in small spacecraft. The antenna, made of a tissue-thin Kapton membrane, packs tightly inside the small satellite for stowage during launch, before deploying to its full size of 2.25 meters in diameter once it reaches low Earth orbit. This high compaction ratio enables larger antennas in smaller satellites, enabling satellite owners to take advantage of volume-limited launch opportunities while still providing significant capability. The mission could help validate emerging concepts for a resilient sensor and data transport layer in low Earth orbit – a capability that does not exist today, but one which could revolutionize global communications by laying the groundwork for a space-based internet."Rapid acquisition of small satellite launch capabilities is increasingly important to US Government organizations like DARPA. The ability to rapidly space-qualify new technology and deploy space-based assets with confidence on short notice is a service that didn't exist for dedicated small satellites until now," says Rocket Lab founder and CEO Peter Beck. "We're honored to provide Electron's agile and flexible launch service to DARPA and we look forward to delivering the innovative R3D2 payload to orbit."The mission, the first of monthly Electron launches this year, will lift-off fr om Rocket Lab Launch Complex 1 on the Māhia Peninsula of New Zealand. To ensure precise insertion and responsible orbital deployment, the R3D2 payload will be deployed via the Electron Kick Stage to a circular orbit. Using this unique launch method, Electron's second stage is left in a highly elliptical orbit wh ere the stage is subject to significant atmospheric drag, causing it to de-orbit and burn up to nothing in a reduced time frame. The Kick Stage is then used to deploy the satellite payload to a precise orbit, following which the Kick Stage can perform a de-orbit burn to speed up its re-entry, leaving no orbital debris behind in space.The Rocket Lab Electron launch experience is the world's first customized small satellite launch service. With the choice of two Rocket Lab launch sites, and the ability to rapidly launch to orbit as frequently as every 72 hours, each mission is tailored to the customer requirements. For the first time, small satellite customers are enjoying unmatched flexibility, responsiveness and control over their own orbit.

The antenna, made of a tissue-thin Kapton membrane, packs tightly for stowage during launch and then will deploy to its full size of 2.25 meters in diameter once it reaches low Earth orbit.R3D2 will monitor antenna deployment dynamics, survivability and radio frequency (RF) characteristics of a membrane antenna in low-Earth orbit. The antenna could enable multiple missions that currently require large satellites, to include high data rate communications to disadvantaged users on the ground. A successful demonstration also will help prove out a smaller, faster-to-launch and lower cost capability, allowing the Department of Defense, as well as other users, to make the most of the new commercial market for small, inexpensive launch vehicles. Satellite design, development, and launch took approximately 18 months."The Department of Defense has prioritized rapid acquisition of small satellite and launch capabilities. By relying on commercial acquisition practices, DARPA streamlined the R3D2 mission from conception through launch services acquisition," said Fred Kennedy, director of DARPA's Tactical Technology Office. "This mission could help validate emerging concepts for a resilient sensor and data transport layer in low Earth orbit – a capability that does not exist today, but one which could revolutionize global communications by laying the groundwork for a space-based internet."The launch will take place on a Rocket Lab USA Electron rocket from the company's launch complex on the Mahia Peninsula of New Zealand. Northrop Grumman is the prime contractor and integrated the 150 kg satellite; MMA Design designed and built the antenna. Trident Systems designed and built R3D2's software-defined radio, while Blue Canyon Technologies provided the spacecraft bus.Rocket Lab will host a webcast and provide coverage of the launch via live stream: http://www.rocketlabusa.com/live-stream.Image Caption: MMA Design successfully completes deployment testing of its innovative high-compaction ratio reflectarray antenna in its Louisville, Colorado facilities.

ЦитироватьRocket Lab launch of DARPA satellite slipsby Jeff Foust — March 6, 2019Rocket Lab's next Electron launch, which was scheduled for late February, has been pushed back to the second half of March because of the delayed arrival of its payload, a DARPA experimental satellite. Credit: Rocket Lab/Trevor MahlmannWASHINGTON — Rocket Lab's first launch of the year, which was scheduled for late February, has been pushed back to the second half of March because of the delayed arrival of its payload, an experimental military satellite.The Defense Advanced Research Projects Agency said March 5 that its Radiofrequency Risk Reduction Deployment Demonstration, or R3D2, satellite arrived in New Zealand March 4 to begin integration with Rocket Lab's Electron vehicle. The launch from Rocket Lab's Launch Complex (LC) 1 in New Zealand is now scheduled for the second half of March.Rocket Lab confirmed the new schedule March 6. "Following a delay to payload arrival, the R3D2 spacecraft is now at LC-1 and integration is underway," the company tweeted. In a later statement, the company said the launch would take place between March 16 and 30 (U.S. time), with four-hour windows each day from 6:30 to 10:30 p.m. Eastern.When Rocket Lab announced the launch in January, the company was targeting late February for the launch. However, a DARPA spokesperson said that the launch was postponed "to provide the prime contractor with additional time to complete payload and spacecraft validation and verification."Northrop Grumman is the prime contractor for R3D2, which will test technologies for deployable antennas. Once in orbit, R3D2 will deploy a Kapton membrane that will expand to a diameter of 2.25 meters to demonstrate the ability to small satellites to carry large deployable antennas needed to support high-bandwidth communications.The 150-kilogram satellite will be the only payload on the launch, the first for Rocket Lab since an Electron launch in December that carried more than a dozen small satellites. The company said in January that the mass and volume of R3D2 took up the entire capacity of the rocket, leaving no room for secondary payloads.Rocket Lab said in January that the launch would be the first of 12 the company plans to perform in 2019 as it shifts into full operations. Most of those launches will take place from LC-1 in New Zealand, although the company intends to carry out at least one launch from its new launch site, LC-2, under construction at the Mid-Atlantic Regional Spaceport on Wallops Island, Virginia. The first launch from that site is scheduled for this fall.Rocket Lab didn't indicate if the delay in the DARPA mission would impact those plans. In a January interview, Rocket Lab Chief Executive Peter Beck said the company expected to increase its launch rate over the course of the year to allow it to reach that total of 12 even though the first launch was, at that time, not scheduled until late February. Beck said that, by the end of the year, Rocket Lab expects to be launching Electrons at a rate of one every two weeks.
