Start rakiety Epsilon - 18.01.2019 / Credits - JAXAOsiemnastego stycznia mała japońska rakieta Epsilon wyniosła na orbitę siedem satelitów.
Do startu doszło 18 stycznia 2019 roku o godzinie 01:50 CET. Start nastąpił z Uchinoura Space Center, położonego w prowincji Kagoshima w południowej Japonii. Lot rakiety przebiegł prawidłowo i siedem satelitów znalazło się na odpowiedniej orbicie.

Głównym ładunkiem w tym locie był satelita Rapid Innovation Payload Demonstration Satellite (RAPIS-1). Celem tego satelity o masie 200 kg jest demonstracja nowych technologii, takich jak układy NBFPGA, zaawansowana komunikacja na paśmie X oraz układ orientacji satelity korzystający z mniej toksycznego paliwa. Misja RAPIS-1 jest planowana na około rok.
Ponadto, rakieta Epsilon wyniosła sześć małych satelitów, z których trzy są formatu CubeSat. Trzy “większe” satelity tego lotu to RISESAT (50 kg masy startowej, Japonia), ALE-1 (68 kg masy startowej, Japonia) i MicroDragon (50 kg masy startowej, Wietnam). Trzy CubeSaty noszą nazwy: OrigamiSat-1, Aoba VELOX-IV i NEXUS.
Był to czwarty lot rakiety Epsilon od czasu wprowadzenia tej konstrukcji do służby w 2013 roku. Jak na razie wszystkie loty tej rakiety zakończyły się pełnym sukcesem. Następny lot Epsilona zaplanowano na 2020 rok – na pokładzie znajdzie się RAPIS-2.

Built by Japanese startup Axelspace for JAXA, the roughly 440-pound (200-kilogram) RAPIS 1 spacecraft will test the performance of a new thin membrane solar panel design, a “green” propulsion system using non-toxic fuel, a high-speed X-band communications system, a low-cost, miniaturized terminal to receive signals from navigation satellites, and a camera suite for Earth observation and to monitor deployment of the solar array, among other prototype technologies.
RAPIS 1 is short for Rapid Innovative payload demonstration Satellite 1, and the satellite also carries a new type of miniature star tracker, and a space radiation monitor experiment. RAPIS 1’s mission is scheduled to last at least two years.
Engineers developed a new payload accommodation structure for the seven satellites launched on the Epsilon rocket. Credit: JAXAAfter deployment of RAPIS 1, the rocket’s upper stage thrusters were programmed to reignite briefly between each satellite’s separation time, ensuring each spacecraft would not collide with one another. The ALE 1 microsatellite, designed to generate a sky spectacle by releasing a shower of tiny particles to re-enter Earth’s atmosphere, was the last of the seven payloads to separate from the rocket around an hour and 10 minutes after liftoff.
“For the first satellite and the last satellite, we will try to adjust to the orbit they want,” said Kyoko Oribe, an engineer at IHI Aerospace, who presented details of the rideshare mission at the International Astronautical Congress last October in Germany.
“For the other satellites, we will attempt slightly different altitudes — one kilometer down, one kilometer down — in order to avoid collisions,” she said. “I expect that this flight will be a (good) development for rideshare.”
The satellite deployments occurred according to plan, JAXA said in a statement.
“All seven satellites separated from the launch vehicle successfully,” the space agency said.
ALE 1 is the first of two satellites launching this year developed by Astro Live Experiences, a privately-funded Japanese venture that aims to create artificial “meteor showers” by releasing half-inch (1-centimeter) pellets to re-enter the atmosphere. By early 2020, the 150-pound (68-kilogram) ALE 1 satellite will use a drag-inducing mechanism to maneuver to an orbit low enough to ensure the particles safely re-enter the atmosphere, and don’t become space junk. The company plans to create the artificial multi-color meteor shower over parts of Japan next year.
“I hope that our man-made meteors will help reveal new discoveries in science, and that it will gather and entertain people under the night sky,” said Lena Okajima, ALE’s chief executive.
ALE is building a second satellite for launch later this year.
Other satellites launched aboard Japan’s Epsilon rocket include MicroDragon, a satellite built by Vietnamese engineers studying in Japan. The 111-pound (50.5-kilogram) spacecraft will be operated by the Vietnam National Space Center, part of Vietnam’s national space agency, and will monitor the world’s oceans to examine fishing grounds and search for disasters such as oil spills. MicroDragon will also measure aerosols, microscopic particles suspended in Earth’s atmosphere.
Vietnamese teams working in collaboration with Japanese universities assembled and tested the MicroDragon satellite in preparation for the launch.
The 130-pound (59-kilogram) RISESAT spacecraft was also launched.
RISESAT stands for the Rapid International Scientific Experiment Satellite, and the project is led by Tohoku University in Japan. RISESAT carries a color Earth observation camera, and experiments to investigate new attitude control and laser communications technologies. The satellite’s payloads come from institutions in Japan, Taiwan and the Czech Republic.
Three CubeSats were also on the launch, all weighing 9 pounds (4.1 kilograms) or less.
One of the CubeSats, named OrigamiSat and developed at the Tokyo Institute of Technology, will unfurl an experimental membrane structure with embedded solar cells and and a UHF antenna to test lightweight systems that could be used on future smallsat missions.
Another CubeSat, named Aoba VELOX-IV, is from the Kyushu Institute of Technology in Japan. It will demonstrate an attitude control and orbital control system, and a low-light camera, for lunar observations.
Nihon University’s NEXUS CubeSat will test next-generation amateur satellite communications technology.
Friday’s flight marked the fourth launch of Japan’s Epsilon rocket since 2013, and the first Epsilon mission to deliver multiple satellites to orbit. (...)
