Satellites and spacecraft are generally complex to build on the ground, expensive to launch and obsolete in a decade or less.
These objects end up floating in orbit around the planet contributing to the pollution surrounding the Earth. But what if there was an alternative?
That’s the question David Barnhart, director of USC’s Space Engineering Research Center and lead for the Space Systems and Technology group for the USC Information Sciences Institute, is contemplating. What if we could just “grow” spacecraft, repurpose a hybrid of inorganic and organic materials and even allow food to grow in space?
TAQNIA and KACST signed an agreement on February 21, 2016, to form a joint venture that will be responsible for developing six or more sub-meter resolution imaging satellites.
KACST will construct, integrate, and launch the satellites, and it will own 50% of the satellites’ imaging capacity inside of KACST’s communication cone, which includes Saudi Arabia and the surrounding region. And, DigitalGlobe will have rights to the other 50% of the capacity inside this region and 100% of the satellites’ capacity outside of the region.
WESTMINSTER, Colo.–(BUSINESS WIRE)– DigitalGlobe, Inc. (NYSE: DGI), the global leader in earth imagery and information about our changing planet, today announced the formation of a joint venture with TAQNIA, a firm dedicated to accelerating technology development for the Kingdom of Saudi Arabia, in partnership with KACST to develop a constellation of highly capable small imaging satellites to support the needs of customers around the world.
Japan is studying the black holes.
This week the Japan Aerospace Exploration Agency (JAXA) successfully launched a new space observatory designed to study black holes, dying stars and the history of galaxy clusters. The X-ray Astronomy Satellite, known as ASTRO-H, will be able to detect X-rays more than 10 times fainter than its telescope predecessor, Suzaku.

Nano Satellite could be interesting and even expanded upon especially as we look to expand the usage of Quantum Technology across various wireless devices in the future as well as microbot technology to enable connectivity to the cloud and other wireless devices.
The nano-satellite, which is among ISRO’s important missions, will monitor air pollutants that pollute cities including Delhi, Lucknow, Amritsar and Allahabad.
The nano-satellite will weigh 15kg and placed 500 km above the earth.
Satellites in outer space will soon provide broadband internet to some remote regions of the world, thanks to a company called ViaSat, in partnership with Boeing.
By 2019, three ViaSat satellites will dispatch a whopping one-terabit internet connection to obscure residential areas in the Americas, Asia, Europe, the Middle East, and Africa. They will also provide connectivity to airplanes in flight and even maritime vessels in the middle of the oceans, which have always previously been drastically removed from anything approaching broadband.
Presently in development at Boeing, ViaSat’s three-satellite system will reportedly offer double the capacity of all the 400 communications satellites already in orbit around the Earth combined. It’s existing technology, just re-executed to be way more efficient.
GPS is an utterly pervasive and wonderful technology, but it’s increasingly not accurate enough for modern demands. Now a team of researchers can make it accurate right down to an inch.
Regular GPS registers your location and velocity by measuring the time it takes to receive signals from four or more satellites, that were sent into space by the military. Alone, it can tell you where you are to within 30 feet. More recently a technique called Differential GPS (DGPS) improved on that resolution by adding ground-based reference stations—increasing accuracy to within 3 feet.
Now, a team from the University of California, Riverside, has developed a technique that augments the regular GPS data with on-board inertial measurements from a sensor. Actually, that’s been tried before, but in the past it’s required large computers to combine the two data streams, rendering it ineffective for use in cars or mobile devices. Instead what the University of California team has done is create a set of new algorithms which, it claims, reduce the complexity of the calculation by several order of magnitude.
The next-generation satellites from ViaSat could have more bandwidth than the 400 communication satellites already in orbit.
ViaSat plans to launch three satellites to provide 1 terabit per second internet connections to remote areas, aircraft, and maritime vehicles.
ViaSat, a US-based satellite company, has teamed up with Boeing to build three new satellites that will provide high-speed Internet to remote areas around the world. This joint project was announced two days ago. ViaSat is scheduled to launch its satellite ViaSat2 on a SpaceX Falcon 9 rocket in just a few months.
These three new satellites, named ViaSat3, will be carrying a total network capacity of a whopping 1 Terabit per second, triple the capacity of ViaSat2. It will be able to deliver 100 Mbps service to remote residential areas in the Americas, Asia, Europe, the Middle East and Africa.
It seems like every day, a video or image emerges that appears to show a UFO near the International Space Station. And it generally — OK, always — turns out not to be a UFO. It’s normally space debris, light reflections from the station windows, an antenna attached to the station, etc.
But wouldn’t it be interesting if someone actually launched a satellite into Earth orbit (illustrated above), with the specific mission of trying to detect and prove unknown objects are actually out there?
