Last year was a busy one for suborbital flights as Jeff Bezos’ Blue Origin and Richard Branson’s Virgin Galactic conducted a combined four flights of their crewed suborbital vehicles. Despite hopes to the contrary, neither company flew paying tourists on their spaceships.
There were also 26 sounding rocket launches that carried scientific experiments and technology payloads above the atmosphere. The year saw:
Japanese startup Interstellar Technologies conduct a successful launch of its Momo commercial sounding rocket;
Texas-based Exos Aerospace continue to struggle with its reusable SARGE booster; and,
the first suborbital launch ever achieved by college students.
The Japan Timesreports that Interstellar Technologies fourth launch of is Momo rocket failed on Saturday.
The vehicle only reached an altitude of 13 kilometers following the launch at 4:20 p.m., falling into the sea some 9 kilometers (about 5.5. miles) offshore from Taiki, Hokkaido, its test site, Interstellar Technologies said.
The rocket is the same model as Momo-3, measuring about 10 meters long, 50 centimeters in diameter and weighing 1 ton.
After failed attempts in 2017 and 2018, the startup finally found success with its third launch in May, with the rocket reaching an altitude of around 113 km before falling into the Pacific Ocean.
Founded in 2013 by former Livedoor Co. President Takafumi Horie, Interstellar Technologies aims to develop low-cost commercial rockets to carry satellites into space.
The third time was the charm for Interstellar Technologies.
On Saturday, the company’s suborbital Momo-3 rocket lifted off from its launch pad in Hokkaido and reached an altitude of 110 km (68.4 miles) before falling into the Pacific Ocean about 10 minutes later, The Japan Timesreports.
“It was a complete success. We’ll work to achieve stable launches and mass-produce (rockets) in quick cycles,” company founder Takafumi Horie told The Japan Times.
Measuring 10 meters in length and 50 centimeters in diameter and weighing 1 ton, it was first due to be launched Tuesday, but that launch was shelved due to a glitch in the fuel system.
It was the venture company’s third launch attempt after previous tries failed in 2017 and 2018. In 2017, the operator lost contact with Momo-1 shortly after launch. In 2018, Momo-2 only made it some 20 meters off the ground before crashing and bursting into flames due to a problem with a control system.
The MOMO sounding rocket is designed to carry a payload weighting up to 20 kg (44 lb) on suborbital flights at a cost of approximately ¥50 million (~$450,000).
Interstellar is also developing the ZERO booster to carry payloads weighing up to 100 kg (220.5 lb) to a 500 km (310.7 mile) sun synchronous orbit. The company hopes to conduct ZERO’s first flight test in 2020.
There were 15 flight tests of eight suborbital boosters in 2018, including six flights of two vehicles — Virgin Galactic’s SpaceShipTwo and Blue Origin’s New Shepard — that are designed to carry passengers on space tourism rides.
The race to provide launch services to the booming small satellite industry also resulted in nine flight tests of six more conventional boosters to test technologies for orbital systems. Two of the boosters tested are designed to serve the suborbital market as well.
A pair of Chinese startups took advantage of a loosening of government restrictions on launch providers to fly their rockets two times apiece. There was also suborbital flight tests of American, Japanese and South Korean rockets.
Throughout the Space Age, suborbital flight has been the least exciting segment of the launch market. Operating in the shadow of their much larger orbital cousins, sounding rockets carrying scientific instruments, microgravity experiments and technology demonstrations have flown to the fringes of space with little fanfare or media attention.
The suborbital sector has become much more dynamic in recent years now that billionaires have started spending money in it. Jeff Bezos’s Blue Origin and Richard Branson’s Virgin Galactic both made significant progress last year in testing New Shepard and SpaceShipTwo, respectively. Their achievements have raised the real possibility of suborbital space tourism flights in 2019. (I know. Promises, promises…. But, this year they might finally really do it. I think.)
The world’s launch providers were extremely busy in the first half of 2018, with China and the United States battling for the lead.
There with 55 orbital launches through the end of June, which amounted to a launch every 3.29 days or 79 hours. The total is more than half the 90 launches attempted in 2017. With approximately 42 missions scheduled for the last six months of the year, the total could reach 97. (more…)
Video Caption: Interstellar Technologies, founded by popular internet service provider Livedoor’s creator Takafumi Horie, launched the unmanned rocket, MOMO-2, from a test site in Taiki.
The outlandish, Ferrari-driving Horie — who helped drive Japan’s shift to an information-based economy in the late 1990s and the early 2000s but later spent nearly two years in jail for accounting fraud — founded Interstellar in 2013. However, privately backed efforts to explore space from Japan have so far failed to compete with the government-run Japan Aerospace Exploration Agency.
Japanese Startup:Nikkei Asian Review has an interview with Takahiro Inagawa, CEO of Interstellar Technologies, about his company’s plans to develop a cheap booster for launching small satellites. “Our focus is not to develop high-end rockets but something simple and affordable, just like the Super Cub (Honda Motor’s popular small motorbike),” Inagawa said. The company plans its first sounding rocket launch this summer. http://asia.nikkei.com/Tech-Science/Tech/Hokkaido-startup-aims-high-in-small-satellite-launches
Orders for Virgin Galactic’s LauncherOne: Business Insider Australia reports that Australian startup Sky and Space Global plans launch part of its constellation of voice and data network nanosats aboard Virgin Galactic’s LauncherOne. “It is expected to not only deliver substantial cost savings, due to LauncherOne’s ability to carry multiple nano-satellites simultaneously, but will enable us to bolster our bandwidth capacity as we launch further nano-satellites into orbit,” said company founder Meir Moalem. http://www.businessinsider.com.au/australias-sky-and-space-is-using-virgin-galactic-to-launch-nanosatellites-2016-6
UPDATE: The agreement is only a letter of intent, which falls short of firm orders for launches.
Virgin Galactic Fundraising: Sky News says that Richard Branson is raising up to $300 million for “existing shareholders” for Virgin Galactic. “The latest injection of capital is aimed at accelerating the development of Galactic’s commercial satellite venture and expanding production capacity at the company’s headquarters,” Sky News reports. Virgin Galactic declined to comment. http://news.sky.com/story/1716551/branson-injects-cash-into-galactic-space-race
