Although Google has been filing patents for the design of an advanced high-altitude balloon network for some time now (examples one and two) and CEO Larry Page talking up Project Loon with Charlie Rose at a TED Conference, it appears that they’re simultaneously dreaming of another Moon Shot project related to a communications satellite constellation wrapped around the globe.

In 2014 Google signed a 60 year lease with NASA airfield and hangers. The Verge reported at that time that “Google may use Hangar One, as well as two sequentially named hangars on the airfield, as a space for research, development, assembly, and testing of technology related to robotics, aviation, space exploration, and other new fields once it moves in. Perhaps Google’s recent patent application discovered at the US Patent Office for a new satellite constellation is one of the many projects that they have on their drawing board.

Google’s patent FIG. 1B noted below shows us a schematic view of exemplary orbital paths or trajectories of the satellites in their proposed system.

SpaceX has finally landed its Falcon 9 rocket on a drone ship at sea, after launching the vehicle into space this afternoon. It’s the first time the company has been able to pull off an ocean landing, after four previous attempts ended in failure. Today’s success is a crucial milestone for SpaceX, as it shows the company can land its rockets both on solid ground and ocean.

This is the second time SpaceX has successfully landed one of its rockets post-launch; the first time was in December, when the company’s Falcon 9 rocket touched down at a ground-based landing site in Cape Canaveral, Florida, after putting a satellite into space. Now that SpaceX has demonstrated it can do both types of landings, the company can potentially recover and reuse even more rockets in the future. And that could mean much greater cost savings for SpaceX.

Mastering the ocean landing is going to be important, since that’s the type of landing SpaceX will probably conduct more often. At a recent NASA press conference, Hans Koenigsmann, vice president of mission assurance for SpaceX, said the next two to three flights will involve drone ship landings. Ultimately, the company expects to land one-third of its rockets on land, and the rest at sea.

Satellite manufacturing today is a lengthy, meticulous process; its high tech nature, and the cost in time and money make advances slow compared to sectors like the mobile industry. But an explosion in demand for connectivity and other space services is driving the need for ever-more capable satellites. It is at this crossroads, that bold new ideas are being forged.

Next week, astronauts on the International Space Station are getting a brand new room. Called the BEAM, short for Bigelow Expandable Activity Module, the room is launching on top of one of SpaceX’s rockets on Friday; it will then be attached to the ISS sometime within the next four months. The BEAM, which is created by private company Bigelow Aerospace, will remain deflated during launch, but once in orbit, it will inflate up to four times its size, providing more overall volume for the interior of the ISS.

The BEAM isn’t a permanent addition to the space station, though. It will only stay attached to the ISS for two years, and the astronauts will go inside the habitat very rarely. That’s because the main goal of the BEAM is to test out if this expandable habitat technology actually works. A successful mission could be the first step to something bigger: an era when expandable space habitats orbit the Earth, allowing for scientists and tourists to visit these “space hotels.”

The concept of expandable spacecraft isn’t new. In the 1960s, NASA launched a series of expandable communication probes called the Echo satellites, which looked like big metallic balloons. The satellites inflated in space and turned into mirror-like reflectors that bounced signals from one spot on Earth to another. Since then, NASA and other private companies have toyed with the idea of scaling up expandable spacecraft so that they could house humans in space.

Looking for partners.

[Via Satellite 03-28-2016] The U.S. Defense Advanced Research Projects Agency (DARPA) is reviving its in-orbit servicing efforts through a new public-private partnership program called Robotic Servicing of Geosynchronous Satellites (RSGS). Under the RSGS vision, the partners would join a DARPA-developed modular toolkit, including hardware and software, to a privately developed spacecraft to create a commercially owned and operated Robotic Servicing Vehicle (RSV). DARPA would contribute the robotics technology, such as the previously developed Front End Robotic Enabling Near-Term Demonstration (FREND) robotic arm, expertise, and a government-provided launch. The commercial partner would contribute the satellite to carry the robotic payload, integration of the payload, and the mission operations center and staff.

DARPA seeks to develop and demonstrate the RSV on orbit within the next five years. The agency’s goals include demonstrating safe, reliable, useful and efficient operations in or near Geostationary Earth Orbit (GEO), demonstrating on live GEO satellites in collaboration with commercial and U.S. government spacecraft operators, and supporting the development of a servicer spacecraft with sufficient propellant and payload robustness to enable dozens of missions over several years.

DARPA plans to kick off the public-private partnership via a program solicitation in the near future. Shortly thereafter, DARPA will host a proposers day to provide potential partners with further details about the RSGS program. The agency plans to share the solicitation along with the date and location of the proposers day on the Federal Business Opportunities (FBO) website in the future.

The year 2016 is a big year for China’s aerospace industry, as several rockets will be sent into space, including Tiangong-2, an orbiting space lab and Shenzhou-11, a manned spacecraft with two people on board.

Two new types of rockets will be launched in 2016. Long March-7, scheduled to be launched in June, will put the country’s first cargo ship, Tianzhou-1, into space in the first half of 2017 to dock with Tiangong-2 and conduct experiments.
