JAXA plans to test a pulse detonation engine next month that uses shock waves to create thrust. The Japanese space agency believes the system could be used for deep-space exploration.
“This experiment is the world’s first flight demonstration of rocket engine technology that safely and efficiently converts shock waves (explosive waves) generated when a mixed gas of fuel and oxygen reacts explosively into thrust,” JAXA said. “Technology of the detonation engine system (DES) combines a pulse detonation engine (PDE) that intermittently generates shock waves and a rotary detonation engine (RDE) that continuously rotates shock waves in a donut-shaped space.”
The experiment will be launched aboard the S-520-31 sounding rocket from Uchinoura Space Center in Kagoshima Prefecture. The launch is set for July 20 from 5:30 to 6:00 JST. The launch window extends from July 20 until Aug. 31.
“In addition, for the purpose of acquiring large-capacity experimental data, we will also conduct an experiment in which the separation capsule is slowly lowered offshore and recovered by helicopter,” JAXA said.
Suborbital launch used to be a sleepy field that rarely attracted much public attention. Let’s face it, atmospheric research and student experiments are not front-page news. Sounding rockets don’t have the majesty and power of a Falcon 9 or Atlas V.
In recent years, exciting new entrants in the field and widespread streaming of launches have made suborbital flights exciting. Last year saw important suborbital flight tests by SpaceX, Blue Origin, Virgin Galactic and Skyrora that garnered worldwide interest.
TOKYO (JAXA PR) — The Japan Aerospace Exploration Agency (JAXA) has signed a contract to launch the Earth observation satellite LOTUSat-1 for Vietnam developed and manufactured by NEC Corporation (NEC) on the Epsilon rocket from Uchinoura.
We have signed a contract with NEC for launching the the observatory. This launch is scheduled for 2023, and this is the first time that the Epsilon rocket has been commissioned to launch an overseas satellite payload.
The year 2018 was the busiest one for launches in decades. There were a total of 111 completely successful launches out of 114 attempts. It was the highest total since 1990, when 124 launches were conducted.
China set a new record for launches in 2018. The nation launched 39 times with 38 successes in a year that saw a private Chinese company fail in the country’s first ever orbital launch attempt.
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…)
The world’s launch providers have been extremely busy in the first quarter of 2018, with 31 orbital launches thus far. This is more than one third of the 90 launches conducted last year.
China leads the pack with 10 successful launches. The United States is close behind with a total of nine launches with one failure. The tenth American launch is scheduled for Monday afternoon from Florida.
Japan successfully launched the SS-520 small satellite booster for the first time on Saturday.
JAXA reports the TRICOM-1R satellite successfully separated from the rocket 7 minutes 30 seconds after liftoff from the Uchinoura Space Center. The space agency says the 3U CubeSat, which carries an imaging camera and a store-and-forward communications system, is functioning normally.
It was the second launch attempt for the SS-520, which failed during its maiden flight in January 2017. The upgraded sounding rocket is equipped with a third stage that enables it to place a 3U CubeSat weighing 4 kg (8.8 lb.) into orbit.
UPDATE: SpaceX has scrubbed for the day due to the need to replace a sensor on the second stage. The next launch window is Wednesday, Jan. 31. __________
A SpaceX Falcon 9 launch scheduled for late this afternoon will kick off a busy period of international launches that will see the inaugural launch of the Falcon Heavy and China’s sixth orbital mission of 2018.

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.
SpaceX is set to close out the year with a night launch from Vandenberg Air Force Base on Friday. The The Falcon 9 booster with 10 Iridium Next communications satellite is set to take off at 5:27 p.m. PST. It will be the company’s 18th launch attempt of the year and the 29th for U.S. launch providers.
The SpaceX mission is one of six launches set for the rest of the rest of the year (see list below). If all flights go forward in the next 10 days, there will be a total of 91 orbital launches worldwide in 2017.
Launch Vehicle: Falcon 9 Payloads: Iridium Next 31-40 communications satellites Launch Time: 0127:23 GMT on 23rd (8:27:23 p.m. EST; 5:27:23 p.m. PST on 22nd) Launch Site: Vandenberg Air Force Base, California

The failure of a Russian Soyuz booster to orbit a weather satellite and 18 CubeSats on Tuesday was the sixth launch mishap of the year. That total includes five total failures and one partial failure out of 79 orbital launches.
On Jan. 14, the maiden launch of Japan’s SS-520 microsat booster failed after takeoff from the Uchinoura Space Centre. JAXA said controllers aborted second-stage ignition after losing telemetry from the rocket. The booster was carrying the TRICOM-1 nanosat.
A second launch has been scheduled for Dec. 25. The SS-520 is an upgraded version of a Japanese sounding rocket.
The maiden flight of Rocket Lab’s Electron booster failed after launch from New Zealand on May 25. Company officials said controllers terminated the flight after faulty ground equipment lost telemetry from the booster, which was functionally nominally. Rocket Lab is gearing up for a second launch attempt that could occur in December.
China’s Long March 3B suffered a partial failure on June 19 after launch from Xichang. An under performing third stage left the ChinaSat 9A communications satellite in a lower-than-planned orbit. The spacecraft reached its proper orbit using on board propulsion, with a reduction of its orbital lifetime.
On July 2, a Chinese Long March 5 booster failed after liftoff from the Wenchang Satellite Launch Center. The rocket was carrying an experimental geostationary satellite named Shijian 18. It was the second launch and first failure for China’s largest booster. Officials have no announced the cause of the failure.
India’s PSLV rocket suffered a rare failure when the payload shroud failed to separate during a launch on Aug. 31. The IRNSS-1H regional navigation satellite was lost. The booster is set to return to service on Dec. 30.
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…)
