Rocket Lab returns to an attempt to carry out its first electronic missile operation, called "The Time of the Year". The mission will launch six satellites, two for Spire Global, two new passengers for Fleet Space Technologies, with the launch of two Proxima satellites, one for GeoOptics Inc. and one for the Irvine CubeSat STEM program as well as a high-tech demonstrator High Performance Space Structure Systems GmbH. The missile was scheduled to rise in June before rising, requiring resettlement in November. The boot window opens at 03:00 UTC on Sunday morning, with the current T-0 tracking 3:50 UTC.
It is the countdown of working time and flight profile:
With its business hours, the launch platform is on the southern edge of the Māhia peninsula on the northern New Zealand Island, the scene is set for the first electronic flight electron mission after two test flights, one in May 2017 and one earlier this year in January 2018.
At T-7 hours, the Rocket Lab launch team proceeds to the console at the Start Control Center to monitor the final activities in front of the liftoff. All roads to the launch area are closed at the T-6 hour mark. this is followed by engineers who lift Electron in a vertical position and feed the missile with kerosene RP-1 (missiles) in T-4 hours and counting.
The launch pad is discharged by all staff in T-2 hours and 30 minutes, and the LOX starts at T-2 hours. This is followed on the T-1 hour mark with the onset of the local aviation authority advising the launch of the launch and launch sites in an effort to avoid damage to the airspace range in front of an expected lift away from.
Should the countdown begin to be programmed, the final team poll and the verification of the vehicle and ground conditions, the final preparations for launch will start from the minute T-10, with the automatic start and its computers Electron to initiate the T-2 launch sequence and count.
The ignition of the nine Rutherford engines at the base of the first phase of the Electron will be commanded by the rocket computers in the T-2 seconds. All nine engines will rebound to full thrust and undergo sanitary controls before releasing the vehicle from the launch pad to T0.
Based on computer systems and the responsiveness of the electronic command, if the need to stop the countdown occurs after the engine is started, an interruption can be triggered only 0.1 seconds before the launch – with the systems responding to enough time to prevent the release of Electron from the cushion and the safe closure of the nine Rutherford engines.
The liftoff will take place at Launch Complex 1 at the first orbiting launch station of the Māhia Peninsula – New Zealand and the first private launch site in the world.
After lifting, Electron will lower the nitrogen to an azimuth that will introduce the vehicle to a 85 degree pitch. After 2 minutes 42 seconds of flight, the nine first-stage Rutherford engines will close, followed by three seconds later than the separation of Stage 1.
The second stage, powered by a single vacuum-optimized Rutherford engine, will ignite at T + 2 minutes 48 seconds, and the unloading of the load will then be separated later in T + 3 minutes and 6 seconds. At T + 9 minutes 12 seconds, Electron will reach orbit; the second stage will be terminated after three seconds with a total delivery time of 9 minutes of 15 seconds.
Five seconds after the end of stage 2, the second stage will stand out from the third stage, the Curie race. At this point, Electron and its payloads will be in a 500 x 250 km (310 x 155 miles) orbit, with an inclination of 85 degrees to the equator.
The Curie kick and five payload elements will be delivered for 41 minutes 41 seconds before the kickstage flies to T + 51 minutes 1 second. The Curie burn will last for 1 minute and 6 seconds, ending in T + 52 minutes 7 seconds to cycle the track ahead of the payload separation.
During the entire start-up phase, if the need for termination of the mission arises, the flight termination command may either be manually shipped from the ground or executed automatically by the built-in rocket computers. For Electron, a flight termination event would result in a command sent to shut down the Rutherford engines – a flight termination option known as throttle termination.
Beneficial working hours are:
All in all, Business Time will bring seven payloads, six satellites and one tech demonstrator to launch on Electron's first operational flight. The mission itself is an orchestra between several separate entities and presents the different capabilities of Electron electronics in the small launch market of satellites.
According to Rocket Lab, the originally scheduled payload mass for this flight was just over 40kg (88 lb), much less than the maximum payload of 225kg and the nominal payload of 150kg (331 lb) Electron. 500 km of sun sync track. This allowed – during the secession from the previous attempt to add the two fleet satellites to the manifest.
Two LEMUR-2 satellites, a single satellite for GeoOptics Inc., IRVINE01 CubeSat, and NABEO for High Performance Space Structure Systems GmbH will participate.
The two LEMUR-2 satellites, called LEMUR-2-ZUPANSKI and LEMUR-2-CHANUSIAK, start for Spire Global data and analysis company. Spire previously launched two LEMUR-2 satellites on the previous Electron, Still Testing flight in January 2018. These two new LEMUR-2 satellites will participate in the Spire constellation for more than 50 nanosatellites currently in Low Earth Orbit.
The LEMUR-2 satellites are used by Spire Global Vessel Tracking Data (AIS) for tracking ship movements in the most remote parts of the globe. Satellites also use GPS Radio Occultation to monitor weather. In the first for Spire Global, the two LEMUR-2 satellites launched at Business Time will be the first to use the Auto-Tracking Service (ADS-B) to activate Spire's AirSafe Aircraft Tracking Service.
These will be the 74th and 75th LEMUR-2 satellites launched for Spire Global and the 78th and 79th general nanoelectronics that will launch for the company since launching their first small satellite in 2013 and developed later that year Kibo Laboratory of the International Space Station.
We start the incredible exciting @irvinecubesat on the satellite #ItsBusinessTime, built by high school students in Irvine, California. It is such a privilege to open access to the track for such works. @IPSFinfo #CubeSats #TimeToFly pic.twitter.com/SAqyEJQxr0

The LEMUR-2 satellite connection is a single satellite for GeoOptics Inc. The satellite was manufactured by Tyvak Nano-Satellite Systems in Irvine, California, the first of Tyvak's two co-operatives to be launched at the time.
The second is IRVINE01 CubeSat – which Tyvak Nano-Satellite tying systems provided mechanical support and served as an integration partner. IRVINE01 itself is a collaboration of 150 high school students from six Irvine schools under the Irvine CubeSat STEM program and was funded by private donations at the Irvine Public Institutions Foundation.
The Irvine CubeSat STEM program is a partnership between the Irvine Public Institutions Foundation, the Irvine Unified School District and the Tustin Federal District School for training and the inspiring next generation of STEM professionals, consisting of students from six public schools in Irvine (Beckman , Irvine, Northwood, Portola, University and Woodbridge) and brings together the objective of assembling, testing and operating a low-Earth satellite.
Through this program, students develop and practice STEM skills in technical documentation and communication, project management, hardware and software, mechanical and electrical subsystems, programming, radio and optical communications and data analysis. Students also acquire technical skills through practical experience and guidance from professionals in the industry as well as invaluable skills such as communication, problem solving and teamwork.
IRVINE01 will be the first attempt to successfully launch the CubeSat built at the California and the West Coast schools in the United States and allow students to operate CubeSat to place antennas, solar panels and camera for optimal operation as well as collection data that students can evaluate and share for further study.
Specifically, IRVINE01 carries a low-resolution camera that takes photos of Venus, stars and other sky objects, with images used to calculate distances from stars and determine the accuracy and stability of the satellite.
The latest payload element is a technology demonstrator: NABEO, a steering wheel distributor designed and manufactured by High Performance Space Structure Systems GmbH, which will test the passive ejection capability of inactive small satellites using atmospheric drag.
The NABEO protester, which starts at Business Time, will use a small cloth, an ultra-thin film, which will be spirally spiraling into the spacecraft for launch and then developed as soon as the satellite reaches the end of its working life.
Reflexes, ultra-thin membrane panels will unfold at a size of 2.5 square feet (8.2 square feet), and then increase the surface of the spacecraft by the resistance of atmospheric particles at its operational height.
The higher the resistance will pull the satellite back to Earth faster than normal, allowing a faster take-off of the spacecraft, thus reducing the amount of garbage space in the LEO. The hope is that this type of system could be incorporated into future spacecraft to help make responsible use of the Earth's trajectory, eliminating the garbage of space when satellites reach the end of their business life.
