In a tweet, SpaceX CEO Elon Musk says two prototype broadband data-transmitting satellites are working well enough to be used for playing video games.

SpaceX President Gwynne Shotwell sees satellites as bigger market than rockets
SpaceX is taking a commanding role in the rocket business — but Gwynne Shotwell, the company’s president and chief operating officer, expects the satellite business to be more lucrative.
Shotwell sized up SpaceX’s road ahead in a CNBC interview that aired today in connection with the cable network’s latest Disruptor 50 list. For the second year in a row, the space venture founded by billionaire Elon Musk leads the list.
How 3D Printing Is Unlocking A New Space Race
A new space race is in the works, thanks to 3D printing. This time around, it’s not about large government agencies vying to blast human astronauts into uncharted territory. Instead, today’s competitors are aerospace startups like Rocket Lab and Relativity Space that are trying to launch satellites into orbit.
Iridium to complete next-generation satellite deployment
WASHINGTON — Iridium expects to have its next-generation satellite constellation deployed and in service by this fall as it looks to win approvals for new maritime and aviation applications.
In a conference call with reporters May 14, Iridium Chief Executive Matt Desch said the remaining three launches of Iridium Next satellites should be completed by the third quarter of this year, with the satellites in the final positions shortly thereafter.
“All of the satellites are going to be in place within probably about 30 days of our final launch,” he said. The Iridium operations team has become more efficient in maneuvering new satellites into their planned orbital slots and putting them into service. “It will be very shortly after our final launch that we will have 100 percent Iridium Next satellites.”
A spectacular destination for astronomy fans is being built in rural Norway
The facility, which was originally used by the US military to spy on Soviet satellites during the Cold War, is undergoing a major overhaul to attract tourists and researchers alike. In search of inspiration, Snøhetta’s designers took astronomy classes and were captivated by the architecture of the galaxy.
“We learned about the eight shaped analemma diagram that the moon and the sun makes if you watch them from the same point over 365 days,” says Skaare. “We were especially inspired by the ‘ugly moons’ of Mars, with its funny shape,” she says referring Phobos and Deimos, the red-planet’s two lumpy satellites.
Mars’s lumpy-potato moons, in fact, inspired the shape of Solobservatoriet’s visitor cabins. Surrounding the planetarium are several imperfect-sphere rooms for stargazers who want to spend the an evening in the forest—perhaps to catch the spectacular Northern Lights. Designed to accommodate groups of two to 32, the cabins will be loosely scattered around the planetarium, by design.
NASA Just Launched a Mars Lander That Will Dig Deep into the Red Planet
A mission like no other.
NASA successfully launched its InSight lander Saturday, setting off its mission to Mars.
The InSight lander – short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport – is set to arrive on Mars in November 2018. It was launched attached to the Atlas V rocket from the Space Launch Complex 3 at Vandenberg Air Force Base in California before it later detached to make its way over to the Red Planet.
The successful launch also marks NASA’s first interplanetary mission to take off from the West Coast, according to the Associated Press. InSight will explore more of Mars than has ever been studied before. InSight will dig close to 16 feet into the surface of Mars to study the planet’s temperature. It will also take the first measurements of marsquakes. The Atlas V rocket also brought on two mini satellites that will follow the InSight on its mission.
Tiny satellites named Wall-E and Eva are about to take a trip to Mars. Will they survive?
But if the tiny satellites do successfully work, similar low-cost satellites could be sent to other distant planets and moons, making communication with Earth from these deep reaches of space easier, and in some cases, possible at all.
When NASA lands a spacecraft on another planet, scientists generally need to have a “relay satellite” to beam images and measurements back to Earth.
Space exploration is hugely expensive, and cubesats could provide a much cheaper way to relay this information back home, rather than building and launching heavy spacecraft.
If Trump Gets His “Space Force,” It Would Likely Be Used to Defend Mining Operations
For one thing, it appears to violate international law, according to Congressional testimony by Joanne Gabrynowicz, a space law expert at the University of Mississippi. Before NASA’s moon landing, the United States—along with other United Nations Security Council members and many other countries—signed the 1967 Outer Space Treaty. “Outer space, including the moon and other celestial bodies,” it states, “is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means.” The 1979 Moon Agreement went further, declaring outer space to be the “common heritage of mankind” and explicitly forbidding any state or organization from annexing (non-Earth) natural resources in the solar system.
Major space-faring nations are not among the 16 countries party to the treaty, but they should arguably come to some equitable agreement, since international competition over natural resources in space may very well transform into conflict. Take platinum-group metals. Mining companies have found about 100,000 metric tons of the stuff in deposits worldwide, mostly in South Africa and Russia, amounting to $10 billion worth of production per year, according to the U.S. Geological Survey. These supplies should last several decades if demand for them doesn’t rise dramatically. (According to Bloomberg, supply for platinum-group metals is constrained while demand is increasing.)
Palladium, for example, valued for its conductive properties and chemical stability, is used in hundreds of millions of electronic devices sold annually for electrodes and connector platings, but it’s relatively scarce on Earth. A single giant, platinum-rich asteroid could contain as much platinum-group metals as all reserves on Earth, the Google-backed Planetary Resources claims. That’s a massive bounty. As Planetary Resources and other U.S. and foreign companies scramble for control over these valuable space minerals, competing “land grabs” by armed satellites may come next. Platinum-group metals in space may serve the same role as oil has on Earth, threatening to extend geopolitical struggles into astropolitical ones, something Trump is keen on preparing for. Yesterday he said he’s seriously weighing the idea of a “Space Force” military branch.
