Posted by in categories: business, information science, robotics/AI, satellites

WASHINGTON – The National Geospatial-Intelligence Agency has selected a team of commercial and academic partners to build an artificial intelligence system with synthetic data, which will further help the agency determine how it builds machine learning algorithms moving forward.

Orbital Insight was issued a Phase II Small Business Innovation Research contract by the NGA, the company announced. Dec. 16. It will collaborate with Rendered.ai and the University of California, Berkeley, to develop a computer vision model.

As the organization charged with analyzing satellite imagery for the intelligence community, NGA has put increased emphasis on using AI for its mission. The agency sees human-machine pairing as critical for its success, with machine learning algorithms taking over the rote task of processing the torrent of satellite data to find potential intelligence and freeing up human operators to do more high level analysis and tasks.

Stanford’s gecko-inspired robot hand sets its sights on fruit picking

Posted by in categories: robotics/AI, satellites

Stanford’s made a lot of progress over the years with its gecko-inspired robotic hand. In May, a version of the “gecko gripper” even found its way onto the International Space Station to test its ability to perform tasks like collecting debris and fixing satellites.

In a paper published today in Science Robotics, researchers at the university are demonstrating a far more terrestrial application for the tech: picking delicate objects. It’s something that’s long been a challenge for rigid robot hands, leading to a wide range of different solutions, including soft robotic grippers.

Visualizing the propagation path of electromagnetic waves from space to ground

Posted by in categories: particle physics, satellites

Using data on electromagnetic (EM) waves and plasma particles measured simultaneously via multiple satellites, an international collaborative research group has discovered the existence of invisible “propagation path” of EM waves and elucidated the mechanism by which EM waves propagate to the ground.

It is known that various kinds of EM occur naturally in geospace and cause variations in the plasma environment that surrounds the Earth via a known as wave–particle interaction. In particular, when geospace storms occur due to disturbances of sun and solar wind, EM waves become more active, and variations of geospace environment sometimes, may cause damage to spacecrafts, expose astronauts to radiation, and cause terrestrial power grid failures. To understand variation in the plasma environment caused by EM waves in , in-situ measurement has been performed in space using spacecrafts, such as the Japanese geospace satellite Arase.

As EM waves in space propagate far away from their origin, to correctly understand the effects of EM waves, it is crucial to understand where in space the EM waves are generated and how they are propagated. However, it has been difficult to unravel the origin of EM waves and the mysteries of how EM waves spread spatially using only single-point observation. “Electromagnetic ion cyclotron waves (EMIC waves),” which are the focus of this study, are an important class of EM wave in geospace that control variations in the geospace plasma environment. The source region of ion mode waves has a finite spatial extent, and generated EMIC waves are considered to propagate north to south along the geomagnetic field lines. The specific spatial size of the EMIC wave source region and the 3D aspect of how the propagation path is formed from space to ground are yet to be elucidated.

After 10 Days of Dangerous, Careful Work, James Webb has Been Fully Fueled up

Posted by in category: satellites

After many MANY delays, the James Webb Space Telescope is fully-fueled and ready for the final stage of preparations before launch (still on for Dec. 22nd)!


On Oct. 12th, 2021, after years of waiting and cost overruns, the James Webb Space Telescope (JWST) finally arrived safely at Europe’s Spaceport in Kourou, French Guiana. The crews began unboxing the next-generation observatory and getting it ready for integration with the Ariane 5 rocket that will take it to space. Then, an “incident” occurred where a clamp band suddenly released, sending vibrations throughout the facility. Once again, the JWST’s launch date was pushed back while crews investigated the source of the problem.

South Africa’s SumbandilaSat Reaches the End of its Design Life

Posted by in categories: climatology, government, satellites

The South African satellite, SumbandilaSat (Pathfinder in Venda) is reaching the end of its life and will deorbit on Friday 10 December 2021.

The satellite was launched in 2009 and took a total of 1,128 high-resolution, usable images. In addition, these imageries were applied in local research and on the Copernicus (previously GMES: Global Monitoring for Environment and Security) programme. The data also contributed towards disaster management such as flood monitoring in Namibia and fire campaigns in the Kruger National Park in South Africa. Furthermore, it also recorded timely images of the Fukushima nuclear disaster and the Tuscaloosa tornado in the USA.

In May 2005, the then DST (Department of Science and Technology) of the South African Government commissioned Stellenbosch University and SunSpace to develop the ZASat pathfinder satellite program (later renamed SumbandilaSat), a technology demonstrator in conjunction with the South African industry. Consequently, SumbandilaSat was delivered 15 months later and launched from Baikonur, Kazakhstan on September 17 2009 with monitoring and satellite support from the SANSA Space Operations facility in Hartebeesthoek.

SpaceX converts Falcon Heavy core into Falcon 9 booster

Posted by in categories: military, satellites

More than two years after the rocket’s last launch, SpaceX appears to have finally decided to give at least one of two surviving Falcon Heavy Block 5 cores a new lease on life as a Falcon 9 booster.

Known as B1052, the Falcon Heavy side core or booster debuted in April 2019 as part of the first flight of the rocket’s Block 5 variant, successfully launching Saudi Arabia’s large Arabsat 6A communications satellite to an almost 90,000 km (56,000 mi) transfer orbit. Following in the footsteps of the first Falcon Heavy, the first Block 5 vehicle repeated its predecessor’s iconic double-landing back at Cape Canaveral. Just 74 days later, both Falcon Heavy Block 5 side boosters B1052 and B1053 launched again, this time supporting the US military’s long-delayed STP-2 rideshare and qualification mission.

Uganda to Launch its First Satellite in 2022

Posted by in categories: health, satellites

Uganda is preparing to launch its first satellite by August 2022. The satellite, PearlAfricaSat-1, is the latest mission from the Joint Global Multi-Nation Birds Satellite project. The initiative began in October 2019 as part of a directive by Uganda’s President to develop a National Space Agency and Institute.

Uganda signed the collaborative research agreement with the Kyushu Institute of Technology (Kyutech), Japan. The agreement involved enrolling and upskilling three graduate engineers to design, build, test, and launch the first satellite for Uganda. Consequently, Japan registered three Ugandan graduate engineers, including; Bonny Omara, Edgar Mujunu, and Derrick Tebuseke.

The core missions for PearlAfricaSat-1 are a multispectral camera payload. The Multispectral Camera mission will provide about 20-metre resolution images for Uganda to facilitate water quality, soil fertility, and land use and cover analysis. The satellite will play a vital role in the oil and gas operation by monitoring the East African crude oil pipeline. This will enable accurate weather forecasts by gathering remote sensor data for predicting landslides and drought. Once the satellite reaches orbit, an Uganda ground station will monitor its health status for a few days before it starts executing its mission.
