Space Flight Laboratory reports dual launch of atmospheric microsats

Space Flight Laboratory (SFL), a developer of 52 distinct microspace missions, has announced the successful launch and deployment of the GHGSat-C1 greenhouse gas monitoring microsatellite and the Slovenian NEMO-HD Earth observation microsatellite. SFL developed the small satellites at its facility in Toronto.

Both satellites were in contact with ground control within hours of their launch on September 2, 2020, aboard an Arianespace Vega rocket from the Guiana Space Center in French Guiana, South America. The satellites are healthy and operating as planned.

"Congratulations to GHGSat Inc. of Montreal and SPACE-SI of Slovenia for making these groundbreaking microspace missions a reality," said SFL Director, Dr. Robert E. Zee.

Established at the University of Toronto Institute for Aerospace Studies (UTIAS) in 1998, SFL has developed CubeSats, nanosatellites, and microsatellites that have achieved more than 126 cumulative years of operation in orbit. These microspace missions have included SFL's trusted attitude control and, in some cases, formation-flying capabilities. Other core SFL-developed components include modular (scalable) power systems, onboard radios, flight computers, and control software.

"Our space-proven attitude control and precise pointing technologies were major factors in winning the development contracts for GHGSat-C1 and NEMO-HD," said Zee.

GHGSat Inc. awarded SFL the development contract for GHGSat-C1 ("Iris") after building the pathfinding GHGSat-D ("Claire") microsatellite launched in 2016. Using high-precision target tracking capabilities developed by SFL, Claire successfully demonstrated that sources of methane and other gas emissions could be detected and measured from space. SFL is currently developing another microsatellite, GHGSat-C2, for the company.

"The GHGSat-C1 mission is critical to GHGSat, and we knew we could rely on SFL to deliver our satellite. In addition to the normal challenges of spaceflight, SFL overcame a litany of launch delays beyond their control to make this mission a success. That's the kind of service that keeps customers coming back to SFL," said Stephane Germain, President of GHGSat Inc.

Precise pointing made possible by a stable platform at a relatively low cost was also a factor in Slovenia's selection of SFL to build the NEMO-HD Earth observation microsatellite. It will capture 2.8-meter resolution high-definition multispectral imagery and video for use in a variety of applications. The microsatellite itself is only 60x60x30 centimeters.

SFL's heritage of on-orbit successes includes missions related to Earth observation, atmospheric monitoring, ship tracking and communication, radio frequency signal geolocation, technology demonstration, space astronomy, solar physics, space plasma, and other scientific research.

Clemson doctoral candidate uses rockets to surf the Alaskan sky
Clemson SC (SPX) Aug 12, 2020
When you think of surfing and Brazil, the first image that comes to mind is probably warm waves crashing on a white sand beach, not a cloud of gas swirling 65 miles above the Earth. But the latter is exactly what was found by Clemson University researcher Rafael Mesquita, a native of Brazil. Mesquita and a multi-institutional research team documented "surfer waves" in the upper atmosphere that create a pipeline of energy between layers in space. Just like ocean waves crash onto the beach, the atmo ... read more
