Government signs contract with Rocket Lab

Sept. 16 (BusinessDesk) - The government has authorised the first commercial space rocket launches from New Zealand.

Rocket Lab, which operates a private satellite launch site on the Mahia Peninsula between Napier and Gisborne, intends to start launch operations later this year, Minister for Economic Development Steven Joyce said in a statement. The contract is an interim measure, preceding the Outer Space and High Altitude Activities Bill which will be introduced to Parliament this month to provide a regulatory regime for space launches from New Zealand.

The government wants the bill passed into law by mid-2017, Joyce said. In June, New Zealand signed the Technology Safeguards Agreement (TSA) with the United States government, which allows commercial entities, including Rocket Lab, to import launch technology and satellites from the US.

"This contract is an important milestone in the work the government is doing to support the development of a New Zealand-based space industry," Joyce said. "Rocket Lab is capitalising on some of New Zealand's advantages as an attractive location for space launches. We have clear skies, access to good launch angles, a skilled workforce and an innovation-friendly business environment."

Rocket Lab is backed by Silicon Valley investor Khosla Ventures, Stephen Tindall's K1W1 fund, Silicon Valley venture capitalist Bessemer Venture Partners, and global defence group Lockheed Martin. In July last year, it signed a contract with the US's National Aeronautics and Space Administration letting it use NASA's resources.

Before launching, Rocket Lab needs to obtain a licence from the US Federal Aviation Administration (FAA) so it can conduct its space launch activities in New Zealand, Joyce said.

Mahia Rocket Lab launch site officially opened

Press Release: New Zealand Government
Hon Steven Joyce
Minister for Economic Development
27 September 2016
Media Statement

Mahia Rocket Lab launch site officially opened

Economic Development Minster Steven Joyce today opened New Zealand's first orbital launch site, Rocket Lab Launch Complex 1, on the Mahia Peninsula on the North Island's east coast.

"I congratulate Chief Executive and founder Peter Beck and his team who have worked hard to achieve this," Mr Joyce says. "It is their innovation and perseverance that has made this day possible.

"I'm looking forward to the first launches fr om Mahia expected later this year, with more to come next year when Rocket Lab launches with commercial payloads."

"Rocketlab is just one of the most visible of hundreds of new generation kiwi hi-tech companies that are rapidly growing high-value exports and leading New Zealand into a hi-tech future."

Mr Joyce acknowledged the landowners from whom Rocket Lab had leased the land for the launch facility, and the people of Mahia and Wairoa.

"The farmland is leased from Onenui Station of the Tawapata South Māori Incorporation who have thought outside the square to explore new opportunities for shareholders. And local people have been very supportive of this new development in their backyard," Mr Joyce says.

"Rocket Lab will be a catalyst for other space-related activity in New Zealand. Space activity is pervasive in our lives, to such an extent we are no longer aware that our internet, our decision-making around energy and resource management, our marine surveillance to name only a tiny fraction, all rely on what we are doing in space.

"Attracting international players will be easier now that we are establishing a world-leading regulatory regime to be managed by a new NZ Space Agency, located within the Ministry of Business, Innovation and Employment.

"The new Agency has been very busy not only supporting Rocket Lab to navigate the regulatory environment, but also putting in place the foundations for an internationally credible, competitive and well-connected New Zealand-based space industry.

Mr Joyce says the NZ Space Agency will be capitalising on Rocket Lab launches to help build New Zealand's capacity and expertise in all manner of space-related activities and will support the strategic opportunities that are likely to flow.

The Outer Space and High Altitude Activities Bill was introduced to The House on 19 September and it is intended it will become law by mid-2017. It will enable the development of a space industry in New Zealand, and ensure its safe, secure and responsible operation. It also provides for the management of certain high altitude activities that take place from New Zealand and enables New Zealand to manage risks and implement certain international obligations relating to space activities and space technology.

https://rocketlabusa.com/rocket-lab-launch-complex-1-ready-for-launches/
Rocket Lab is pleased to announce the completion of the world's first private orbital launch complex, Launch Complex 1.
Located on New Zealand's Mahia Peninsula, Launch Complex 1 is set to enable the highest frequency of space launches in history. The facility will be the primary site for launches of Rocket Lab's Electron vehicle, designed to lift a 150 kg payload to a 500 km sun-synchronous orbit.
New Zealand's remote island location and low volume of marine and air traffic create ideal conditions for frequent launch opportunities. In addition, launches from the site can access a uniquely wide range of orbital inclinations – from 39 degrees through sun-synchronous.
Facilities at Launch Complex 1 include a vehicle processing hangar wh ere the vehicle will be prepared for launch as well as a 50 tonne launch platform. The platform will tilt forward to lift the rocket to a vertical position prior to launch.
Satellites launched from the complex will be used to provide services including optimized crop monitoring, improved weather reporting, internet from space, natural disaster prediction, up-to-date maritime data and search and rescue services.
Rocket Lab has completed major milestones this year with the qualification of the 3D printed Rutherford engine, qualification of the second stage of the Electron rocket and the development of major infrastructure including remote tracking, test facilities and the launch site. The company is currently working through the qualification of the first stage of the Electron rocket and will look to begin the test flight phase once qualification and launch licencing are complete.

Rocket Lab launch site go for lift-off
 9:30 AM Tuesday Sep 27, 2016

Rocket Lab has opened its launch site at Mahia - the world's first private orbital launch complex.
The Auckland-based company plans to launch its first test rocket fr om the site at the tip of the Mahia Peninsula before the end of the year.
The site - in an area with little air traffic - will enable high frequency launches once the Rocket Lab programme gets to a commercial stage.
It will be the primary launch site for the 17m tall Electron rocket although lift off fr om sites overseas are possible.
Other launch pads overseas for rockets going into orbit are government-owned.
"Completing Launch Complex 1 is a significant milestone in the build-up to the first test flight of the Electron vehicle," said Rocket Lab founder and chief executive Peter Beck.
The facility was opened today by Economic Development Minister Steven Joyce.
The opening was also attended by 180 locals, officials, Rocket Lab staff and members of the newly formed New Zealand Space agency within the Ministry of Business, Innovation and Employment.
Customers signed to fly on Electron include NASA, Planet, Spire and Moon Express. With a dedicated launch priced at $6.7 million to $7.6 million, Electron will take small satellites into low earth orbit at a fraction of the cost of overseas competitors.
Beck said it was ''wonderful'' to celebrate the completion of the site with those who had welcomed the company into the community.
Wherever possible, Rocket Lab hired local contractors to develop the site. Facilities at Launch Complex 1 include a vehicle processing hangar wh ere the rocket will be fuelled up with liquid oxygen and kerosene and prepared for launch.
The platform will tilt forward to lift the rocket to a vertical position prior to launch.
There has been some concerns raised locally and by Greenpeace about the environmental impact of the programme, specifically parts or the rocket falling to earth.

The carbon fibre vehicle weighs over 12 tonnes and is fitted with a kill switch that can be activated by specialist ground crew at the site if it strays off course. Mission control will be at Rocket Lab's base near Auckland Airport.
The company is not putting a date on the first launch, one of three planned test flights before it carries any satellites.
It has warned sightseers that due to the nature of testing, there is a likelihood of 'scrubbed' launches.
 

Completing Launch Complex 1 is a significant milestone in the build-up to the first test flight of the Electron vehicle.

''Rocket Lab recommends viewing a launch in the commercial phase rather than the test phase - we value your time, and wouldn't want to keep you waiting.''
There was a possibility of a space tourism industry, wh ere facilities are put in for rocket buffs who travel long distances to watch launches.
Rocket Lab says Wairoa District Council is evaluating the location of viewing platforms to be installed for the commercial phase of launches.

"...И поскольку сейчас их планы несколько прояснились и конкретизировались – то вот апдейт:
Их космодром на Mahia Peninsula построен, состоялось его официальное открытие, и получена государственная лицензия на космические пуски с космодрома.

Кстати, это первый в мире частный космодром. Фирмы SpaceX и Orbital ATK – они имеют свои частные пусковые полщадки – но в рамках государственных космодромов. И многие сервисы, связанные с пуском, они сам не производят, а арендуют у хозяев.
Так что в этом аспекте фирма Rocket Lab – первая. В мире.

Второе: первый пуск ракеты запланирован на середину декабря.
Точнее, в предварительной заявке указан период с последней декады ноября по вторую декаду декабря – но конец периода более реален.

Ещё – на форуме NSF было высказано мнение, что новый космодром Rocket Lab – самый живописный. «The best view ever», так сказать. Ну, не знаю – сравнивать бы надо с Ванденбергом и Tanegashima, – там, говорят, самая красота. Но я там не был.
Можно просто посмотреть , действительно красиво    

И последнее: рынок микро-спутников сейчас демонстрирует бурный рост, поэтому ракета, специально ориентированная на запуск таких спутников – безусловно будет пользоваться спросом. Что, собственно и показывает манифест Rocket Lab.
На следующий год все их пуски – девять штук – уже распроданы. А в 2018 году они планируют 12 пусков – один пуск в месяц.

Вот собственно и всё – осталось пожелать им удачи и – ждать новостей    

PS:
Поскольку в рунете уже есть статьи про «Электрон», и, как водится – с ошибками, то вот правильные величины грузоподъёмности Электрона:
Груз на LEO (200 х 200 км, 39°) = 400 кг;
Груз на SSO (500 х 500 км) = 150 кг."
