Air Force General: “We’d be dumb not to” fly on SpaceX’s reusable rockets

(credit: SpaceX) The increasingly warm relationship between the US Air Force and the rocket company SpaceX appears to be approaching full-on bromance levels. The latest words of lavish praise for SpaceX have come from Gen. John W. Raymond, commander of Air Force Space Command, which oversees launch operations for the US military and national security sectors. In an interview with Bloomberg, Raymond said the potential savings from reusable rockets like the Falcon 9 booster now being flown and reflown by SpaceX are irresistible. “The market’s going to go that way. We’d be dumb not to,” he said. “What we have to do is make sure we do it smartly.” It would be “absolutely foolish” to not begin using them, Raymond said. Before the military can fly its satellites and other payloads on a previously flown booster, the US military has to certify that SpaceX’s “flight proven” boosters are reliable enough. That process already appears to be underway. “I don’t know how far down the road we’ve gotten, but I am completely committed to launching on a reused rocket, a previously flown rocket, and making sure that we have the processes in place to be able to make sure that we can do that safely,” Raymond told Bloomberg.

SpaceX plans to start launching high-speed internet satellites in 2019

Last November, SpaceX asked the FCC for permission to launch 4, 425 satellites to provide high speed internet around the globe. While current satellite internet can be slow and high-latency , the Elon Musk-founded company promises its proposed service will be much better thanks to custom satellites deployed into low-Earth orbit. In a Senate hearing today on US Broadband infrastructure, SpaceX’s vice president of government affairs Patricia Cooper explained the company’s plan, which includes its intention to begin launch operations in 2019. SpaceX hopes to start testing its satellites before the end of this year and continuing through the early months of 2018. If that’s successful, the company plans to launch satellites in phases between 2019 and 2024, after which the system will be at full capacity. SpaceX plans to launch the system with its Falcon 9 rocket , which has been successfully launched and landed with an eye toward re-usability. The entire system, said Cooper, is meant to provide a high volume of broadband capacity at “fiber-like” speeds over a wide area. The company says it’s designed its system to be highly adaptable, too, with the ability to “steer dynamically a large pool of beams to focus capacity where it is needed.” The company also promises that its system will be cost-effective. Cooper concluded her remarks with specific recommendations for current and future regulations, including those that require NGSO systems to launch within six years of licensure. These regulations were written more than 20 years ago, the company argues, and should not apply to modern systems like the one SpaceX is proposing. The company would also like to see more of the national funding for broadband projects. Cooper mentioned that only 1.5 percent of all funds appropriated for broadband infrastructure had been awarded to satellite systems. In addition, SpaceX would like the Senate to reward systems that promote efficient spectrum use, revise specific policies around the use of satellite-specific spectrums and to streamline the licensing process for the same. Oh, and “modernize” the FAA commercial launch regulations, which would allow for more launches per year than is currently allowed. Having a ton of satellites close to Earth providing broadband internet to anyone regardless of location certainly sounds fantastic, and a solid step forward for an increasingly internet-reliant populace. Still, without more specific timelines and operational details, it’s hard to get too excited, even though we secretly are . Via: Ars Technica Source: Senate Remarks, SpaceX’s Patricia Cooper

What Do Luxury Sleeper Cabs for Long-Haul Truck Drivers Look Like?

The life of a long-haul trucker can be tough, even when they’re not behind the wheel. When it’s time to get some shuteye in the truck’s cab, some of them have a scant 36″ behind the seats in which to stuff a twin mattress, and there’s barely enough room to turn around back there, let alone get dressed and undressed. And for the trucker who brings their spouse on the road—yes, husband-and-wife trucker teams exist—it’s simply not enough space for two people to live out of. For those that can pony up for a larger cab, an Indiana-based company called ARI Legacy Sleepers specializes in tricking them out with custom packages suited to the customer’s tastes. Let’s take a look at some of their work. First off, if you see a cab that’s this size, you can bet there’s more behind the rear seats than just a twin mattress. And you’d be right. When you look back between the seats, here’s what you see: And here’s the view looking fore: Overhead is a small, subtle lighting trick that provides the illusion of more space: Using a mirror and one-way mirror to provide “infinity lighting, ” making the LEDS look like they stretch off forever overhead. Close the curtains to the “cockpit” and enjoy your flatscreen in peace. There’s plenty of storage both above and below the kitchen counter, which features an electric stovetop and a sink. When not in use, both have covers that conceal them, providing uninterrupted counter space. This photo below is not the exact same interior, but you get the idea. Also note the mirror above the sink, so the driver can shave. Opposite the counter is a sofa and a little nook to the right of it. You’ll notice a cable management port at back right; one can place a computer, laptop or gaming system here. To the right of that is a door, and the toilet paper holder on the inside of it has probably clued you in… …yep, they’ve got a bathroom in here. A wall-mounted dispenser obviates the need for shelving. Moving back inside the cabin, we see the sofa, which of course has storage beneath it. You might think, “Is that where the driver sleeps?” Not exactly; note the dual tracks in the wall. An elevator bed motors down at the touch of a button. For cabs where there is no rear door, the sofa and bed arrangement can be placed across the rear wall. And as you can see here, the choice of lighting strongly impacts your perception of the space. The lighting scheme in this one here reminds me of The Peach Pit from the original Beverly Hills 90210. And this one below is like The Peach Pit but with hardwood floors. With spaces this small, the materials choice also makes a profound visual impact. This one here is owned by a married couple who both go on the road together, and I imagine it must recall what their actual home looks like, aesthetically: Another customer has opted to have his look like more of a bachelor pad: And for drivers who plan to do some open-air sightseeing during downtime, there’s an option to haul your Harley. Yep, if you’ve got the space you can have a motorcycle “garage” with side-loading ramp installed: You can check out more of ARI’s custom designs here , and they also have a good amount of photos on their Facebook page .

The International Space Station’s network bandwidth will be doubled by new upgrades

 The internet connection on the International Space Station and other platforms in orbit is getting a serious upgrade that will double its capacity, NASA announced today. But they aren’t sending up a new router or satellite; the improvements are mainly terrestrial. The ISS and dozens of satellites rely on the Space Network, a more or less unified architecture for sending large amounts of… Read More

SpaceX wants to launch 4,425 internet satellites

SpaceX has just asked the FCC for permission to launch 4, 425 satellites that can provide high-speed (1 Gbps) internet around the globe. That’s more than thrice the current number of active satellites orbiting our planet, based on the data posted by the Union of Concerned Scientists. SpaceX chief Elon Musk first talked about the project back in 2015, wherein he revealed that it would cost the company $10 billion and that it will operate out of the private space corp’s new Seattle office. One of its earliest investors is Google, which contributed $1 billion to the initiative. The satellites the company plans to launch will be much bigger than CubeSats at 850 pounds each and will be designed to last five to seven years before they decay. They’ll be orbiting our planet from 714 to 823 miles above the surface, higher than the space station that typically maintains an altitude of around 268 miles. According to the FCC filing, the project has two phases: SpaceX will initially launch 800 satellites that can provide internet services in the US and other locations. Once all 4, 425 satellites are in orbit — it could take five years to launch them all — the array will be able to provide 1 Gbps connection to users across the globe. Besides providing details about the project, the FCC filing has also revealed the kind of power Elon Musk wields over SpaceX. Apparently, Musk has a 54 percent stake in the space corporation, more than twice his 22 percent stake in Tesla. Source: FCC , Business Insider , SpaceX

A tiny space pebble just put a huge dent in an ESA satellite

The European Space Agency’s Copernicus Sentinel-1A satellite has new 40cm dent on one of its solar wings — and it was caused by a tiny millimetre-size piece of space debris. The impact was discovered with the Sentinal-1A reported a slight power reduction last month. Onboard cameras quickly found the micrometeoroid impact, pictured above. Don’t worry, the ESA says the satellite is fine, but the impact serves as a reminder: at orbital velocity, tiny objects can cause major damage. This is a problem for the Breakthrough Starshot project , which aims to launch a laser powered nanocraft that travels at 1/5th the speed of light. That project hopes to reach the next solar system over in about 20 years. “Erosion of solid surfaces will be a severe problem at these speeds, ” says Ian Crawford of Birkbeck, University of London. “It’s possible that the wafersats won’t even be able to complete the journey.” For engineers, this isn’t news — NASA and other space agencies have been combating space derbies for decades — but it does mean that teams need to think of new ways to protect fast moving crafts. The faster a craft goes, the more dangerous tiny objects can be. At the speed Breakthrough Starshot is designed to reach, even microscopic space dust could be dangerous. Source: New Scientist , ESA

Hubble discovers that dwarf planet Makemake has a moon

The Hubble telescope has spotted a shadowy moon with a charcoal black surface orbiting the dwarf planet Makemake. Astronomers first observed Makemake in 2005, but since it’s the second brightest icy dwarf planet after Pluto , it took some time to see a satellite that’s 1, 300 times fainter than the celestial body it’s orbiting. Also, it’s positively tiny with a diameter measuring 100 miles across, making it but a fraction of our own moon that has a diameter measuring 2, 159.2 miles. The Hubble team used the telescope’s Wide Field Camera 3 and the same technique that found Pluto’s satellite’s in 2005, 2011 and 2012 to discover Makemake’s companion that has been christened “MK 2.” NASA says its presence can tell us more about the dwarf planet, including its density. “Makemake is in the class of rare Pluto-like objects, so finding a companion is important, ” Southwest Research Institute’s Alex Parker said. “The discovery of this moon has given us an opportunity to study Makemake in far greater detail than we ever would have been able to without the companion.” Astronomers plan to look more closely into the satellite to find out if it’s the “warm region” they’ve been seeing on Makemake’s surface, which is inconsistent with its icy shell. They also intend to observe its movements: a tight orbit means it’s the product of a collision, while a wide one means it was captured from the Kuiper belt. Either way, MK 2 — just like our Earth’s own satellite — has been orbiting Makemake for billions of years. Via: Space Source: Space Telescope Science Institute , NASA
