Nine small satellites will launch to Earth orbit atop a Japanese rocket tonight (Sept. 30).
An Epsilon rocket is scheduled to carry off from Japan’s Uchinoura Space Center tonight throughout a 4-minute window that opens at 8:51 p.m. EDT (0051 GMT on Oct. 1). If a livestream of the launch turns into out there, Space.com will carry it stay.
The Epsilon will haul to orbit the Rapid Innovative Payload Demonstration Satellite 2, or RAISE 2 for brief, and eight tagalong spacecraft for the Japan Aerospace Exploration Agency (JAXA).

As its full title suggests, the 240-pound (110 kilograms) RAISE 2 is a expertise demonstrator. The spacecraft, which was constructed by Mitsubishi Electric Corp., will check six completely different space applied sciences, together with a small sensor referred to as MARIN designed to gauge the place, altitude and velocity of orbiting satellites, JAXA officials said.
The different eight satellites, which had been manufactured by quite a lot of Japanese firms and universities, are even smaller than the three.3-foot-wide (1 meter) RAISE 2. Four of the rideshare spacecraft weigh 8.8 kilos (4 kg) or much less, and the opposite 4 tip the scales at between 101 kilos and 137 kilos (46 to 62 kg). (Those satellites will turn into weightless in orbit, in fact, however they will nonetheless have mass.)
The heftiest of the tagalongs is DRUMS (“Debris Removal Unprecedented Micro-satellite”), a craft constructed by Kawasaki Heavy Industries. Once in orbit, the two.75-foot-wide (84 centimeters) DRUMS will launch a small object after which seize it, demonstrating tech that would ultimately assist humanity clear up space junk.
This would be the fifth mission for the 78-foot-tall (24 m) Epsilon, which JAXA started creating in 2007. The solid-fueled rocket is able to delivering to low Earth orbit payloads as heavy as 2,646 kilos (1,200 kg), in line with its JAXA specifications page.
The 4 earlier Epsilon launches — which befell in September 2013, December 2016, January 2018 and January 2019 — had been all profitable.
The 2019 launch lofted RAPIS 1 (“Rapid Innovative Payload Demonstration Satellite 1”), the first payload on the primary mission developed by way of JAXA’s Innovative Satellite Technology Demonstration Program. RAISE 2 is the second mission in that program, which seeks to encourage the event of modern space tech, particularly by universities and the personal sector.
