Udany start rakiety Electron BY KRZYSZTOF KANAWKA ON 5 MAJA 2019
Start rakiety Electron - 05.05.2019/ Credits - Rocket LabPiątego maja 2019 roku rakieta Electron wyniosła na orbitę trzy satelity technologiczne dla amerykańskich sił powietrznych.
Do startu doszło 5 maja o godzinie 08:00 CEST. Start odbył się z wyrzutni Onenui Station znajdującej się w Nowej Zelandii. Na pokładzie tej rakiety znalazły się trzy małe satelity technologiczne dla amerykańskich sił powietrznych (USAF). Lot przebiegł prawidłowo i satelity zostały umieszczone na orbicie o wysokości ponad 400 km i nachyleniu około 40 stopni.
Ten start otrzymał także nazwę
That’s a Funny Looking Cactus. Był to szósty start rakiety Electron i jednocześnie piąty udany. Jest możliwe, że w najbliższym czasie rakiety Electron będą startować średnio raz na miesiąc. Ta rakieta staje się coraz ciekawszym sposobem wynoszenia małych satelitów na niską orbitę okołoziemską (LEO), dość efektywnie konkurującą z innymi rakietami na rynku.

Rocket Lab's CEO, Peter Beck, has confirmed on Twitter that the Curie kick stage performed its orbit circularization burn successfully, and deployed all three satellites.

Rocket Lab intended to launch the mission Saturday, but officials delayed the launch to conduct additional checks on the payloads. The mission’s total payload weight — around 400 pounds (180 kilograms) — made it the heaviest launch by Rocket Lab to date. (...)
The biggest of the satellites launched Sunday is named Harbinger.
Built by York Space Systems in Denver, the Harbinger mission is sponsored by the U.S. Army Space and Missile Defense Command. The roughly 330-pound (150-kilogram) spacecraft hosts several technology demonstration payloads, including a synthetic aperture radar for all-weather Earth observation and a high-data-rate communications link to transmit the radar imagery to users on the ground.
The Harbinger satellite’s radar imaging instrument comes from ICEYE, a Finnish company which has built and launched its own commercial radar observation smallsats. The radar imaging payload on Harbinger “provides commercial access to timely and reliable Earth observation data and is capable of imaging any location on Earth at regular intervals, day or night, regardless of cloud cover,” according to the Army’s fact sheet on the mission.
A high-speed laser communications terminal on Harbinger from BridgeSat will downlink the radar imagery, demonstrating a rapid data collection capability that could be used by tactical military forces on the battlefield.
Harbinger was joined on the Electron launch by two tech demo CubeSats named SPARC-1 and Falcon ODE.
The Space Plug and Play Architecture Research CubeSat-1 — about the size of a briefcase — is a joint U.S.-Swedish military research nanosatellite.
SPARC-1 will test miniaturized avionics, a software-defined radio system, and a visible camera. The mission’s U.S. sponsor is the Air Force Research Laboratory, which developed the mission in partnership with the Swedish Defense Materiel Administration.
The six-unit CubeSat’s prime contractor was ÅAC Microtecs, a Swedish smallsat manufacturer.
The smallest payload launched Sunday was the Falcon Orbital Debris Experiment, a one-unit CubeSat a bit larger than a Rubik’s cube. The Falcon ODE spacecraft, developed at the U.S. Air Force Academy, will release two stainless steel ball bearings in orbit, which will become calibration targets for ground-based space surveillance radars.

Credit: Rocket LabWASHINGTON — A Rocket Lab Electron rocket successfully launched three technology demonstration satellites for the Defense Department May 5 as part of an effort by the military to demonstrate responsive launch.
The Electron rocket lifted off at 2:00 a.m. Eastern from Rocket Lab’s launch site on the Mahia Peninsula of New Zealand’s North Island. The launch was delayed a day in order to perform additional checks of the vehicle’s payload of three satellites. Those satellites were released by the rocket’s kick stage nearly 55 minutes after liftoff.
“Perfect flight, complete mission success, all payloads deployed!!” Peter Beck, chief executive of Rocket Lab,
tweeted shortly after payload deployment.
The rocket was flying a mission for the Defense Department’s Space Test Program called STP-27RD, in cooperation with the Defense Innovation Unit. The three satellites had a combined mass of 180 kilograms, the heaviest payload launched by an Electron to date. The company said that conservative margins for earlier missions, as well as launching to a lower inclination, enabled the heavier payload.
The largest of the three satellites is
Harbinger, a 150-kilogram satellite built by York Space Systems for the U.S. Army Space and Missile Defense Command. The spacecraft will demonstrate synthetic aperture radar imaging capability and high-bandwidth downlink capabilities in a small satellite. The satellite is the first one built by York, a Denver-based smallsat manufacturer, to reach orbit.
Also on the launch is Space Plug and Play Architecture Research CubeSat-1 (SPARC-1), a six-unit cubesat sponsored by the Air Force Research Laboratory in cooperation with the Swedish military to test modular spacecraft avionics. The third satellite is the Air Force Academy’s Falcon Orbital Debris Experiment (Falcon ODE), a one-unit cubesat that will release two stainless steel ball bearings that will serve as calibrated radar and optical targets for ground-based space situational awareness sensors.
The launch is the first for the Air Force’s Rapid Agile Launch Initiative (RALI) program, an effort to make use of commercial launch providers and rapid procurement to provide faster access to orbit for military payloads. Air Force officials said last month
they are planning to launch 21 payloads on five missions this calendar year through RALI, including the STP-27RD flight as well as a launch later this year by Virgin Orbit’s LauncherOne.
The STP-27RD launch, nicknamed “That’s a Funny Looking Cactus,” was the second Electron mission this year and the sixth overall for Rocket Lab. Beck said in an interview last month that the company is planning to move into a monthly cadence of launches for the rest of this year, including demonstrating the ability to perform launches two weeks apart by the end of the year. He added that the company’s 2019 manifest is full.
