LONDON, 12 September 2017 (Inmarsat PR) — Inmarsat has selected Mitsubishi Heavy Industries (MHI) as the launch provider for the first satellite in the Inmarsat-6 fleet.

The satellite, Inmarsat-6 F1, is under construction by Airbus Defence and Space. It is scheduled for launch in 2020 using MHI’s H-IIA launch vehicle.

Inmarsat’s sixth generation (I-6) fleet will be the first to feature dual-payload satellites, each supporting L-band and Ka-band services. The I-6 satellites will represent a step change in the capacity of Inmarsat’s L-band services, supporting a new generation of capabilities – from advanced global safety services and very low cost mobile services to Internet of Things (IoT) applications.

JAXA Begins Tests of H-III Engines

The Nikkei Asian Review reports JAXA began test firings of the LE-9 rocket engine, which will power its new H-III launch vehicle. The first round of testing will include 11 firings through June.

The new booster is set to replace the H-IIA and H-IIB launchers, which are the mainstay of Japan’s orbital rocket fleet. Mitsubishi Heavy Industries and IHI are leading the development of the new two-stage launch vehicle.

H-III is designed to launch payloads at lower costs. The basic configuration can carry 4 metric tons into sun synchronous orbit.  By adding two to four strap-on boosters to the first stage, H-III will be able to lift up to 6.5 metric tons into geostationary transfer orbit.

The new booster will have a base cost of about 5 billion yen ($43.9 million). The H-IIA costs an estimated 10 billion yen ($87.8), with the more powerful H-IIB costing 10 billion yen ($131.5 million).

JAXA’s goal is for the H-III to complete flight tests and enter service in March 2021.

TOKYO & DUBAI, UAE (MHI/MBRSC PR)–Mitsubishi Heavy Industries, Ltd. (TOKYO:7011) (MHI) has received an order for H-IIA launch services from the Mohammed bin Rashid Space Centre (MBRSC), in the United Arab Emirates (UAE), for launch of the Emirates Mars Mission’s (EMM) Hope spacecraft.

In order to better understand the Martian atmosphere and climate, Hope is expected to be launched in the summer of 2020 on MHI’s H-IIA launch vehicle, and is set to arrive at Mars in 2021 to coincide with the 50th anniversary of the founding of the UAE. This order for the EMM marks MHI’s fourth overseas contract for its launch services.
