The end of GEO Satellites as we know today

Posted by in categories: 3D printing, business, robotics/AI, satellites

GEO Satellites business globally make roughly 80% of the overall Space market business with $270B revenues claimed in 2017. How a Space Industry of such kind level of business can disappear is not an argument for many years to come but how a transformation of the Satellite configuration can impact the Space Industry this represents a real topic.

I already discussed in my previous article of how the advancement of A.I. bringing to autonomous missions for satellites, 3D printing permitting on-orbit Manufacturing and Robotic Assembly are not far away technologies, with the mature advancements achieved in on-Ground applications, to be applied to Space Satellites. Already today recently born Startups are working on Satellites on-board software/hardware permitting more autonomous tasks with decision making capability without being piloted from remote on-Ground Stations, significantly reducing operative costs.

Arriving to build fully autonomous Satellites is just a matter of time, with remotely controlled operations to be applied only for safety contingencies. The foreseen growth in the number of small satellites by order of magnitudes push the market this way.

Watch Rocket Lab Launch a Cubesat Fleet for NASA Tonight!

Posted by in categories: business, satellites

The California-based startup Rocket Lab will launch 10 tiny satellites into orbit for NASA tonight, and you can watch it all live online.

A Rocket Lab Electron booster is scheduled to launch NASA’s ElaNa-19 mission from the company’s private Launch Complex 1 on the Mahia Peninsula of New Zealand’s North Island. Liftoff is scheduled for 11:07 p.m. EST (0407 Dec. 13 GMT) during a 4-hour launch window that closes at 3 a.m. EST (0800 GMT). You can watch live via Rocket Lab’s website, beginning about 20 minutes before liftoff. You can also watch the launch here on Space.com, courtesy of Rocket Lab. Bad weather may be a concern for the launch, company officials said.

Tonight’s launch will mark Rocket Lab’s first flight for NASA and the fourth orbital flight of the company’s Electron booster over all. After two test flights (nicknamed “This Is A Test” and “Still Testing”), the company successfully launched its first commercial mission (dubbed “It’s Business Time”) last month.

Chang’e-4 Successfully Enters Lunar Orbit

Posted by in category: satellites

Next stop: the Lunar Farside

China’s Chang’e-4 lunar mission, the first-ever soft-landing endeavor on the lunar farside, launched successfully on 8 December at 02:23 Beijing time (7 December at 18:23 UTC) via a Long March 3B rocket from Xichang Satellite Launch Center. The launch carried a lander and a rover toward the Moon. On 12 December at 8:45 Beijing time (16:45 UTC), the spacecraft arrived in lunar orbit, preparing for a landing in early January.

China Launches 1st Mission to Land on the Far Side of the Moon

Posted by in categories: robotics/AI, satellites

The first-ever surface mission to the far side of the moon is underway.

China’s robotic Chang’e 4 spacecraft streaked away from Earth today (Dec. 7), launching atop a Long March 3B rocket from the Xichang Satellite Launch Center at about 1:23 p.m. EST (1823 GMT; 2:23 a.m. on Dec. 8 local China time).

If all goes according to plan, Chang’e 4 will make history’s first landing on the lunar far side sometime in early January. The mission, which consists of a stationary lander and a rover, will perform a variety of science work and plant a flag for humanity in a region that remains largely unexplored to date.

Experiments at PPPL show remarkable agreement with satellite sightings

Posted by in categories: mobile phones, particle physics, satellites

As on Earth, so in space. A four-satellite mission that is studying magnetic reconnection—the breaking apart and explosive reconnection of the magnetic field lines in plasma that occurs throughout the universe—has found key aspects of the process in space to be strikingly similar to those found in experiments at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL). The similarities show how the studies complement each other: The laboratory captures important global features of reconnection and the spacecraft documents local key properties as they occur.

The observations made by the Magnetospheric Multiscale Satellite (MMS) mission, which NASA launched in 2015 to study in the magnetic field that surrounds the Earth, correspond quite well with past and present laboratory findings of the Magnetic Reconnection Experiment (MRX) at PPPL. Previous MRX research uncovered the process by which rapid reconnection occurs and identified the amount of magnetic that is converted to particle energy during the process, which gives rise to northern lights, and geomagnetic storms that can disrupt cell phone service, black out power grids and damage orbiting satellites.

China mission launches to far side of Moon

Posted by in categories: robotics/AI, satellites

China has launched the first mission to land a robotic craft on the far side of the Moon, Chinese media say.

The Chang’e-4 mission will see a static lander and rover touch down in Von Kármán crater, located on the side of the Moon which never faces Earth.

The payload blasted off atop a Long March 3B rocket from Xichang Satellite Launch Center.

A startup is about to test a ‘gas station in space’ that could one day refuel satellites

Posted by in categories: energy, satellites

Fuel is heavy. And when launching a satellite into space, the amount of fuel you give it determines how long it can stay operational. That is, unless you can refuel at a space gas station.

The news: Startup Orbit Fab is scheduled to launch an experiment to the International Space Station on board a SpaceX Dragon cargo mission tomorrow at 1:38pm EST. Its goal is to test the company’s method of fluid transfer in space. It’ll be launched alongside other scientific experiments to be performed by astronauts on board the station in collaboration with the ISS US National Lab.

The challenge: Refueling and repairing satellites in space requires some expert wrangling, as well as well as the launch of large quantities and types of fuel into orbit. Also, pumping new fuel into a satellite doesn’t work in microgravity the way it does on Earth. Fluids are harder to measure and float around their tanks unpredictably.
