India’s most powerful rocket aced its second orbital flight Wednesday (Nov. 14), setting the stage for a robotic lunar mission in January.  


The Indian Space Research Organization (ISRO) launched the Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III) from the Satish Dhawan Space Centre in Sriharikota at 6:38 a.m. EST (1138 GMT) Wednesday, successfully delivering the GSAT-29 communications satellite into orbit. 


“India has achieved [a] significant milestone with our heaviest launcher lifting off the heaviest satellite from the Indian soil,” ISRO Chairman K. Sivan said in a statement. “The launch vehicle has precisely placed the satellite in its intended orbit. I congratulate [the] entire ISRO team for this achievement.” [In Photos: India’s Most Powerful Rocket Aces 2nd Test Launch!]


The GSLV Mk III’s first orbital test launch, in June 2017, was successful as well. The ISRO also launched an experimental version of the GLSV Mk III in 2014 to test a prototype of a space capsule built to carry three astronauts into space. That mission also succeeded, but it was a suborbital, not an orbital test.

Following the success of Wednesday’s flight, Indian officials declared the rocket ready for operational flights, beginning with the launch of the Chandrayaan-2 lunar lander. That liftoff is currently scheduled for Jan. 30, according to Spaceflight Now


Chandrayaan-2, India’s planned second robotic mission to the moon, consists of an orbiter, a lander and a rover. It is a follow-on mission from the Chandrayaan-1 orbiter, which in 2009 helped confirmed the presence of water ice on the lunar surface. 


India plans to launch Chandrayaan-2 from the Satish Dhawan Space Centre.


The GSLV Mk III is an upgraded version of India’s GSLV Mk II and can haul about double the payload of its predecessor. The new rocket will also be used to launch India’s planned Gaganyaan crewed spacecraft into orbit as early as December of 2021, according to Spaceflight Now. 


Over the next few days, three orbit-raising maneuvers will be performed to position the 6,913-lb. (3,423 kilograms) GSAT-29 satellite in geostationary orbit about 22,000 miles (36,000 kilometers) over the equator. GSAT-29 “is a multiband, multibeam communication satellite, intended to serve as test bed for several new and critical technologies,” according to the ISRO. 


Specifically, the satellite’s payload includes a high-resolution camera and optical communication technology. This tech will use laser communication links to relay information between the ground and geostationary orbit significantly faster than conventional radio communications can.


The launch of GSAT-29 “will help to bridge the digital divide,” K. Pankaj Damodar, GSAT-29 project director, said in the same statement. “Several next-generation payload technologies will be demonstrated with this mission soon.”


Chandrayaan-2’s launch won’t be the next liftoff from Indian soil. That should come on Nov. 26, when the nation’s Polar Satellite Launch Vehicle lofts the Hyperspectral Imaging Satellite and multiple secondary payloads for the U.S. and other international partners.

At Small Satellite Conference, Frustration About Lagging Efforts to Deal With Space Junk

https://www.space.com/42365-space-junk-cleanup-efforts-frustration.html


LONDON — A British debris-removal satellite was deployed this summer from the International Space Station to help researchers figure out 

new techniques to clean up space junk

 that increasingly is becoming a hazard to the ISS and to other satellites.


The experimental RemoveDebris mission  in September successfully cast a net to catch a dead satellite in space. Next year it will try to capture the target with a harpoon.


A harpoon that grabs orbital debris sounds like a cool idea, but putting up more hardware in space to clean up debris is probably not a sustainable proposition, said Fred Kennedy, the director of the Defense Advanced Research Projects Agency’s Tactical Technology Office. [7 Ways to Clean Up Space Junk]


“If I have to bring out a harpoon for every piece of debris, I’m not sure I’ve helped. I may be contributing to the problem,” Kennedy said Nov. 5 at the Small Satellites and Disruptive Technology Focus Day conference hosted by the SMi Group.

During a Q&A session, an industry executive expressed frustration that governments seem to be unable to find a solution to the space debris problem, especially in low Earth orbit. “Couldn’t DARPA do something?” the executive asked Kennedy.


DARPA has studied the problem for years and concluded that some active removal of debris is needed but the long-term answer is self policing, Kennedy said. “If the industry is putting up a thousand satellites, they have to figure this out,” he said. “All the mega constellations are aware, they are working that problem.” The national security community and the civilian space agencies are trying to figure out how to better track debris as part of a larger space traffic management effort. But as broadband satellite companies start building their constellations, Kennedy said, they should have a plan to de-orbit their out-of-service spacecraft.


“It would be much better if companies like SpaceX, OneWeb and Telesat would take care of the problem themselves and have a plan,” he said. “I know they have thought about it.” Their motivation is not just to make space safer for satellites but also to preempt an onslaught of regulations that might come in the future if debris continues to proliferate.


The junk-grabbing satellite tested from the International Space Station has been five years in the making. “The challenge is quite substantial,” said Luis Gomes, chief technical officer of Surrey Satellites Technology Ltd., the company that designed the RemoveDebris spacecraft. So much can go wrong when trying to grab objects in space, he said. “We continue to study and analyze.”


“At first we thought it was a crazy idea,” said Gomes.


The $20 million project is led by the Surrey Space Centre at the University of Surrey and co-funded by the European Commission. The RemoveDebris mission includes four experiments. In September it deployed a net developed by Airbus to capture a target cubesat. The next test is a vision-based navigation system from Airbus that uses 2D and 3D light detection and ranging technology to track a cubesat. The harpoon was developed by Airbus and next year will be fired at 20 meters per second to penetrate a target made of composite material. In the final experiment, RemoveDebris will deploy a large drag-sail to speed de-orbit into the Earth’s atmosphere.


Kennedy said these technology efforts are impressive but impractical. “Clearing all the debris out of LEO is expensive,” said Kennedy. “That’s what I fear. That this takes us to a place where I don’t know if it’s affordable.”


DARPA published a study in 2011 called “The Catcher’s Mitt Study” that looked at the debris problem and its future growth. The report said that active debris removal would be needed at some point to maintain an “acceptable level” of operational risk. It noted that “failure to address this problem has significant implications for the success of future space missions due to the potential increased number of on-orbit collisions with non-trackable, yet lethal, debris fragments.”

How to Enable Hulu’s Night Mode

https://lifehacker.com/how-to-enable-hulus-night-mode-1830527378


I’m a tremendous fan of using the Dark or Night Mode whenever there’s one available. Using a darker theme makes viewing things easier on your eyes (and the eyes of those around you if you’re somewhere like a plane or bed). It can also help save your battery life since displaying black has been proven to use less juice than white.

There are a handful of Chrome extensions out there that can add a dark mode to any website that work with mixed results. If you’re a Hulu user, the service offers a night mode specifically for watching videos through its website which will offer a far superior experience.

To access Hulu’s Night Mode, first go to Hulu on your browser of choice and then log in. From there, click on your name at the top right side of the page.

Screenshot: Hulu / E.Price

A drop-down menu will appear with “Night Mode” listed toward the top along with a toggle switch. Toggle the switch on to enable Night Mode on your profile.

That’s it. If you ever want to turn the feature off, you can do so by just toggling that switch back to the off position.

But look at how great that night mode looks. Why would you ever toggle it off?

Why California Has More Wildfires Than Finland

https://lifehacker.com/why-california-has-more-wildfires-than-finland-1830546028


Photo: Justin Sullivan (Getty Images)

Our President, garbling something the Finnish president said about forest management, believes that the snowy country has fewer wildfires than California because they rake up leaves in the wilderness. Shockingly, this is not true.

As the New York Times reports, Finnish forests benefit from a combination of luck and non-stupid forest management:

  • Finland is cold and snowy, while California is mostly hot and dry. (Finland’s summer temperatures rarely get above 60 degrees Fahrenheit, and around this time of year the weather tends to be wet.)
  • Logging roads crisscross Finland’s forests, slowing down fires while giving firefighters easy access.
  • Aviation clubs are paid to do fire surveillance, looking for fires from the air.
  • Finnish forest managers remove some of the dead trees (not, uh, leaves) to remove a small percentage of the flammable material.

Perhaps we could learn from Finland’s strategies, but no amount of raking will make California wetter or slow down the Santa Ana winds that fan the flames, nor will it eliminate “forest” fires in places that are, like Malibu, not actually made of forests.

What we’re buying: RetroStone’s smart take on retro handheld gaming

https://www.engadget.com/2018/11/19/what-were-buying-retrostone-gaming-retro-handheld/



James Trew, Engadget

The recent spate of retro “classic” consoles might be switching a new audience on to vintage games, but some of us never left them. For most, a $60 – $100 machine with a few flagship titles on it is probably enough to scratch the itch, but Managing Editor James Trew has a much deeper itch: to play retro games on the go without someone choosing the library for him.


James Trew

Much to the bemusement of the rest of Engadget, I have a fetish for the Atari Lynx, of which I own many, and of course, every game ever made for it. So, I already have a portable with all the games I love, why would I want another one? Because logic does not apply here. But if it did, it would be because what was considered portable in 1990 isn’t really pocket-friendly now. Much as I love the Lynx, it’s cumbersome and guzzles batteries like an electric Cookie Monster. I decided to search for something, sleek, modern, and flexible (in case I want to enjoy other platforms too). To my surprise, there’s not a lot of off-the-shelf solutions that meet my weird, specific requirements. (Ok, maybe I shouldn’t be surprised.)

The problem seems to be that retro handhelds come in a few different categories. There are portable “classics” which suffer some of the same problems as their living room counterparts (limited games and no flexibility). There are some that play original cartridges for various systems, but that just seems impractical. Then there are the murky unlicensed knock-off machines on Amazon. I actually bought one of these for comparison (more on that later), but needless to say they’re kinda shoddy, and who wants to play the classic Mario 14 or a sketchy Angry Birds NES port? Not I.

RetroStone

For a while, I had been using a modded PlayStation Portable. This worked pretty well. PSPs are fairly cheap to pick up (I picked mine up for about $50 on eBay), and easy to modify. This also meant I could play PSP titles as well as my Lynx library (I make an exception for ROMS for games I own). Before too long though, the batteries for the PSP kept crapping out and replacements would often be faulty on arrival, or expensive. I considered the PS Vita as an upgrade, but they still go for more than I really wanted to spend, and you need a specific firmware version which makes finding the right one a gamble.

The next logical step was to look at a handheld running RetroPie. There are a few options here, like the Pi GRRL Zero and GameBoy Zero (both, unsurprisingly, based on Raspberry Pi Zero boards). In terms of size, flexibility and functionality, these meet my weird requirements, except they both need to be put together and need a 3D printed case (or shopping around for one you don’t hate). It looks like a fun project, I’m just not after a project right now. I wanted something that had a professionally-made feel to it and was somewhat good to go.

Enter the RetroStone ($156), by 8Bcraft. The RetroStone, with its vintage Game Boy aesthetic, instantly caught my eye. Originally launched on Kickstarter, it runs on a system similar to Orange Pi (a Raspberry Pi alternative), has its own version of RetroPi, and enough buttons to be compatible with many newer systems. Importantly, it comes ready to go, though you have to install the operating system yourself, as open source software generally can’t be “sold.” Fortunately, installation takes about two clicks on a PC to write it to the SD card, and you simply pop that back in the RetroStone.

RetroStone

What I liked most, is that the RetroStone comes with four USB ports and an HDMI out, so you can connect four controllers, plug it into your TV, and voila, you have a living room console too. There’s also a good old-fashioned headphone port and micro-USB for charging (I’m getting about 5 hours of play per charge). Most of the above is true for all Pi-based systems, this one is just well made and requires very little setup. I also just love how it looks (though, I can see it might be an acquired taste). Price-wise it’s in PS Vita territory, but I love the vintage styling and its added desktop capabilities. More on that later.

8Bcraft isn’t a large organization. In fact, as far as I know, it’s a one-man outfit. The RetroStone is the second console from him/them, with the Raspiboy ($87) being the first. The two are similar, but the Raspiboy is a little too quirky-looking (even for my taste), and, as the name suggests uses a lower-spec Raspberry Pi board. It comes as a kit but doesn’t need soldering. As the RetroStone has more processing punch, it can emulate more modern systems (apparently up to the N64/PS1 era, and even some PSP games).

Turns out, that the RetroStone exists purely for people with similar desires as me. Pierre, the man behind the product told me over email “It was very difficult to make a Game boy zero, you had to be an electrician. And when you add the cost of all parts it was pretty expensive. So I thought, why not make something that is accessible and affordable? That’s when I made Raspiboy.” (And then, the RetroStone.)

Another benefit of these “Pi” systems (whichever fruit it is), is that you can use them as portable PCs too (this is their primary purpose after all). With the RetroStone, if I plug in a keyboard and mouse, then connect it to a monitor (or my TV), then you have a full desktop to play with. This is probably not that interesting to most people, but after handheld gaming systems, my next weird tech crush is weird, small, not very practical mini PCs (ILU Nokia N800). Not sure why, but I think it’s a throwback to when the very idea of a functional, pocket-sized PC was kinda mind-blowing.

Yes, I know that I already have a phone that is well made, has oodles of processing power for both gaming and whatever else that fits in my pocket. The thing is, I want something for time away from my phone, not just more phone time. Plus I hate onscreen controls, and grips/adapters aren’t in the spirit of what I want. Like I said earlier, logic doesn’t factor highly in my plans, it’s all about that pure gaming feel.

RetroStone

And the RetroStone has feeling in spades. Every time I glance at it across the room, I have the urge to pick it up and play. I spent far too long researching slightly shitty mini wireless Keyboards (for my wonky portable PC fantasy) and I also had to buy a WiFi dongle, as the RetroStone doesn’t have any wireless at all (it does have an Ethernet port though!).

When I hold the thing, it feels comfortable, and just like a handheld console should (slightly chunky, but not heavy or cumbersome). The buttons feel like an original Game Boy, and the D-pad doesn’t feel slack or spongy. There are four more “shoulder” buttons on the back, which I find a little hard to reach, but none of the games I play right now need them.

The 3.5-inch display is decent; it’s a little low in resolution at 320×240, but that’s more than adequate. The bigger problem is that it uses the composite output (as the board’s HDMI output was needed for the TV out). That said, when I compare it side by side with the PSP running the same emulated game, it’s notably sharper. The PSP is a little blurry/soft looking, despite any tweaking I do in settings (if I am missing something here, let me know).

Game

Also, despite the love and care that has clearly gone into making this thing, you are still reminded that it’s a barebones Linux machine in a nice case. While that $20 thing I bought on Amazon boots up instantly to the game selection menu, the RetroStone goes through a whole PC-like startup process that takes almost a minute. It’s also a little temperamental, sometimes taking a few restarts before it loads up properly.

Right now, the RetroStone is the closest thing to the comprehensive retro gaming experience I am looking for. I love that it has untapped potential as a mini-PC too (and all the other perks of RetroPie, like Kodi and so on). Much as I love my old Lynx (which I paid a princely sum to upgrade the screen on), the portability and design of the RetroStone have won me over.

As enamored as I am with the RetroStone, my quest isn’t over. I know there are likely more contraptions out there, with different reasons to consider (smaller? More powerful? Has other superfluous features that’ll appeal to me?). I’m still even thinking about the PS Vita, for reasons I cannot explain. So, fellow retro gamers, if you happen to know of other systems out there to add to the collection, I’m all ears.

Lockheed Martin is building quiet supersonic jet for NASA

https://www.engadget.com/2018/11/20/lockheed-martin-quiet-supersonic-jet-nasa/



Lockheed Martin

Lockheed Martin’s Skunk Works team has started building the first part of the X-59 Quiet Supersonic Technology aircraft, which could make supersonic commercial travel a reality. The aerospace company is building the jet for NASA’s Low-Boom Flight Demonstration program, now that the space agency has committed to a three-year development timeline. Lockheed X-59’s long, slender design will allow it to be relatively quiet, creating a sound only as loud as a car door closing whenever it transitions to supersonic speeds. Since it will fly at an altitude of 55,000 feet and at speeds of 940 mph, it’s expected to be barely audible.

A quiet supersonic plane could eventually convince authorities to give them permission to fly on land, paving the way for air travel that’s much, much faster than we’re used to. In order to ensure that the project will achieve a noise level that most people will find agreeable, NASA plans to conduct tests using an F/A-18 Hornet aircraft over Texas this month. The aircraft will produce louder sonic booms at sea and quieter ones over land, after which 500 local volunteers will provide feedback.

Lockheed’s Low Boom Flight Demonstrator program manager, Peter Iosifidis, called the start of the manufacturing process “a great leap forward for the X-59 and the future of quiet supersonic commercial travel.” If all goes according to plan, the X-59’s first flight will take place in 2021 and will be used to collect feedback on how acceptable its quieter sonic booms are. According to Lockheed Martin, the results of that test will help NASA “establish an acceptable commercial supersonic noise standard to overturn current regulations banning supersonic travel over land.”
