Despite the COVID-19 pandemic, 2020 was a very busy launch year with a number of firsts in both human and robotic exploration. A total of 114 orbital launches were attempted, with 104 successes and 10 failures. It was the same number of launches that were conducted in 2018, with that year seeing 111 successes, two failures and one partial failure.

On May 21, a Japanese H-IIB rocket roared off the launch pad with the ninth and final H-II Transfer Vehicle (HTV) (Kounotori) resupply ship to the International Space Station (ISS).

But, the launch was not the end of the line for Japanese cargo delivery. The Japan Aerospace Exploration Agency (JAXA) is developing an improved variant known as HTV-X to supply the space station and possibly the lunar Gateway.

HOUSTON (NASA PR) — A Japanese cargo spacecraft loaded with experiment hardware, supplies and spare parts is scheduled to launch from the Tanegashima Space Center in southern Japan to the International Space Station at 1:30 p.m. EDT Wednesday, May 20 (2:30 a.m. May 21 in Japan). The Japan Aerospace Exploration Agency (JAXA) unpiloted H-II Transport Vehicle-9 (HTV-9) carries investigations testing a new livestreaming educational tool, microscope and telescope.

Here are details about some of the scientific investigations and facilities heading to the orbiting lab on HTV-9.

TOKYO (JAXA PR) — Continuous research effort on the high-fidelity numerical simulation to predict various physical phenomenon have been made in research and development directorate.

Efficient development risk identification and mitigation become possible by using numerical simulations rather than the high-cost experiments. In addition, an efficient investigation on the key physics mechanisms are also possible since the detailed physical data distributions are available.
Numerical simulations have been applied to wide variety of design problems such as the H3 rocket, the spacecrafts and the aircrafts.

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.

HOUSTON (NASA PR) — Astronauts aboard the International Space Station plan to conduct what may become a record pace of 10 complex spacewalks during the next three months, a cadence that has not been experienced since assembly of the space station was completed in 2011.

Experts will discuss those plans in a briefing at 2 p.m. EDT Tuesday, Oct. 1, at NASA’s Johnson Space Center in Houston. Live coverage of the briefing and all spacewalks will air on NASA Television and the agency’s website.
