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.
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…)
SpaceX had a banner year in 2017, launching a record 18 times and helping to propel the United States to the top of the global launch table with a perfect 29-0 record. The U.S. total made up 32.2 percent of 90 orbital launches worldwide, which was an increase over the 85 flights conducted in 2016.
The 29 American launches were a leap of seven over the 22 flights conducted the previous year. This is the highest number of American orbital launches since the 31 flights undertaken in 1999. However, that year the nation’s launch providers suffered four failures whereas they were perfect in 2017.
Although orbital launch vehicles get all the glory (and infamy when they fail), 2016 was also a busy year for the far less glamorous suborbital launch sector. There were 19 suborbital launches at various sites around the world, and two more sounding rocket launches of note where the payload didn’t go above 100 km. (more…)
