Suborbital Flights Tested New Launch Vehicles in 2022

Once a sleepy backwater largely focused on scientific research, the suborbital launch sector has boomed in recent years. Private companies and governments across the globe conducted 29 flights to test orbital and suborbital launch vehicles and a range of technologies last year.

A Chinese company launched a reusable suborbital vehicle that took off vertically and landed horizontally at an airport. A second Chinese company conducted a series of launches to support the development of a suborbital space tourism vehicle. South Korea tested two orbital rockets on three suborbital flights. Iran continued to develop satellite launch vehicles. An Indian company broke a government monopoly by launching the first private rocket from the subcontinent. And a Dutch company conducted the maiden flight of a new suborbital launcher.

Let’s take a closer look at these flights.

Chinese Suborbital Launches

On August 26, the China Aerospace Science and Technology Corporation (CASC) launched the Reusable Suborbital Carrier from the Jiuquan Satellite Launch Center. The vehicle flew a suborbital trajectory before landing horizontally on the runway at the Alxa Youqi Airport in the Inner Mongolia Autonomous Region.

CASC said the second launch of the reusable carrier was a complete success. A maiden flight was conducted on July 16, 2021.

CASC has released very little information about its suborbital vehicle, which is believed to have a lifting body shape to allow it to glide to a runway landing.

Space and Hypersonic Programs

Space Transportation, a.k.a., Beijing Lingkong Tianxing Technology, said on its website that it conducted six test flights last year as part of its Tianxing program. The launches were split evenly between Tianxing I and Tianxing II rockets.

Space Transportation’s goal is to develop a suborbital spaceplane capable of carrying tourists and microgravity experiments on suborbital flights. A later variant would enable high-speed transportation between distant cities on Earth in less than two hours.

The company released very little information about the six launches. It’s not even clear where the flights took place, although Wikipedia indicates they might have been conducted from the Jiuquan spaceport.

The image above shows the evolution of the planned test vehicles. The suborbital vehicle would be 15 meters (49 feet) in length. The point-to-point vehicle would be almost 35 meters (115 ft) in size.

Space Transportation has published the following development schedule:

2019-2022: technology verifications through flight tests,
2023: flight test of suborbital space tourism prototype,
2025: crewed flight of space tourism vehicle,
2028: flight test of global hypersonic vehicle prototype, and
2030: completion of full-scale global hypersonic vehicle.

Perigee has received investment from Samsung Venture Investments and LB Investment. The company has also received support from the Korea Advanced Institute of Science and Technology (KAIST), which is a national research institute.

Six days after Perigee’s launch, South Korea’s Ministry of National Defense launched the Solid Fuel Space Projectile with a dummy payload on a suborbital flight. The launch was part of a development program aimed at producing a booster capable of launching 500 kg (1,102.3 lb) satellites into orbit. The first orbital flight is scheduled for around 2024.

South Korea conducted a second suborbital test of the Solid Fuel Space Projectile on Dec. 30. The Ministry of National Defense said the flight was successful.

Skyroot Aerospace Makes History

Skyroot Aerospace made history on Nov. 18 when it became the first private Indian company to launch a rocket. The company reported that its suborbital Vikram-S rocket with three payloads reached an altitude of 89.5 miles (55.6 miles) during its maiden launch.

“Vikram-S rocket meets all flight parameters. It’s history in the making for India,” the company tweeted.

On June 26, Iran launched its new Zulianah satellite booster on a successful suborbital flight test for the second time. The launch was conducted from the Semnan Space Center in Northern Iran.

Zulianah is a three-stage launch vehicle designed to place a spacecraft weighing 220 kg (485 lb) or ten 20 kg (44.1 lb) CubeSats into a 500 km (310.7 mile) high orbit. The booster specifications are:

Length: 25.5 meters (83.7 ft)
Mass: 52 tons (114,640 lb)

First & Second Stages
Motor Diameter: 1.5 meter (4.9 ft)
Fuel: solid
Thrust: 74 tons (725 kN; 163,000 lbf)

Third Stage
Engine Diameter: 1.25 meter (4.1 feet)
Fuels: liquid (UDMH /N2O4)
Thrust: 3.5 tons (35 kN; 7,800 lbf)

Zulijanah is Iran’s third domestically developed launch vehicle; the other two are named Safir and Simorgh. It is the nation’s first satellite launcher to use a combination of solid- and liquid-fuel stages.

Zulijanah’s previous suborbital flight test was conducted on Jan. 31, 2021. Two additional additional test launches are planned.

Zulijanah can be driven to a location and launched using a transporter-erector system with limited preparation. U.S. and European analysts have expressed concerns that Iran might be using the program as a cover to develop an intermediate range ballistic missile.

On Oct. 3, Iran’s Ministry of Defence launched the Saman-1 rocket in a successful test of the booster’s upper stage.

Iran tested the first stage of the Qaem 100 launch vehicle during a suborbital flight conducted on Nov. 5. The three-stage, solid fuel rocket is designed to place an 80 kg ( lb) payload into a 500 km (311 mile) high orbit. Qaem 100 would have twice the payload capacity of the Qased booster.

Skyrora Launch Failure

Skyrora attempt to launch its Skylark L suborbital rocket failed on Oct. 8. Instead of reaching an altitude of 102 km (63 miles), the booster crashed into the Norwegian Sea 500 meters (1,640 ft) away from its launch site in Langanes, Iceland.

Skyrora said the booster suffered an anomaly after liftoff from the mobile launch platform. The company did not identify what caused the rocket to crash.

Despite the failure, Skyrora said the failed flight marked “another milestone on its way to commercial viability and the first vertical orbital launch from UK soil in 2023.” The launch team was able to test “critical processes and components” for the larger Skyrora XL rocket. Skyrora XL will be capable of launching up to 315 kg (694 lb) into orbit.
