DARPA aims to ‘disrupt’ national security space business



DARPA's Fred Kennedy: "Our savior is going to be the commercial sector."

WASHINGTON — The military space business is stuck in its old ways and missing a "golden opportunity" to capture the energy of a rejuvenated commercial industry, said a former White House space and aviation technology adviser who is now a top official at the Defense Advanced Research Projects Agency.
"In the national security space sector, we're in dire need of new thinking and innovation,"  said Fred Kennedy, director of DARPA’s Tactical Technology Office. He assumed that post in September after serving as deputy director since January.

Speaking at a breakfast meeting of the Commercial Spaceflight Federation Nov. 15, Kennedy criticized the Pentagon’s methods for acquiring satellites and called for a “shakeup” in national security space programs.

In the Defense Department, Kennedy said, "We've gotten very good at building small numbers of extremely exquisite things, very expensive things on very long time schedules." That culture that emphasizes high performance and low risk is now working against the military because its satellites have become huge targets for adversaries.

"Our savior is going to be the commercial sector,” said Kennedy. Some pockets within the military are moving in that direction but not soon enough. “We’re starting to see an influx of commercial technology, but we need more of it, and quick."

Kennedy worries that the commercial space boom could turn out to be a fad that fades in a few years, so the Pentagon should be harnessing that energy now. "My biggest fear is that in a couple of years people will forget Matt Damon and 'The Martian' and be back where we were before."

'Other transactions' contracting

DARPA’s weapon for capturing privately funded technology is an authority known as "other transactions," or OTA, to sign contracts with vendors that bypasses some of the federal procurement red tape.

"We do that. It's very effective and useful," said Kennedy. "I can’t say it's always quicker than the normal contracting process. But it is actually an effective way of teaming."

The way it works with DARPA: The agency selects a commercial partner and the company is expected to help fund the venture. "Then we can go out and work on problems jointly," Kennedy said.

A fad, huh. So the Colonization of Mars is seen as a "fad"? A passing ADHD interest that'll lose its' luster in a few years? Nah. That dream of the 50's and 60's, and even the early 70's, when we dared to think that Space was the next great frontier, was killed because of people who worked for DARPA and OldSpace because they were too busy trying to figure out ways to kill other people most efficiently during the Cold War.

 

That's all over with, and they can't get out of that lame-assed midset (being the students of those old idiots) so they have no idea how to deal with the new ideas and new ambitions. Good for them for trying, though.

UW team wins NASA’s nod for small satellites with magnetic braking systems

 

NASA says itll provide resources for a University of Washington research team thats working on a concept to put small satellites in orbit around other worlds using magnetic interactions.

The concept, known as magnetoshell aerocapture, is one of nine university-led technology development projects winning NASAs backing under the Smallsat Technology Partnerships initiative. The nationwide program is managed by NASA’s Ames Research Center in California’s Silicon Valley.

Magnetoshell aerocapture uses magnetic fields and magnetized plasma to help slow down spacecraft and get them into stable orbits. The technology is particularly suited for interplanetary missions involving small spacecraft, where size and weight constraints may rule out using thrusters, physical aeroshells or other weighty deceleration systems.

UW researchers have been working on the technology for years. Last year, an associated team from Redmond, Wash.-based MSNW received a $500,000 NASA grant for ground-based development work on magnetoshell aerocapture.

The technology can turn less than an ounce of plasma into a magnetized deceleration barrier that’s as wide as a football field.
>
The nine newly selected teams will have the opportunity to establish a two-year cooperative agreement with NASA, through which each university will receive up to $200,000 per year. As part of the agreement, NASA researchers will collaborate on the projects. UWs team, for instance, has been paired up with Langley Research Center in Virginia.

To be fair, these aren't even the really good ones. There's stuff floating around in the theoretical arenas that'll boggle the mind just waiting for R&D funding. :yes:

Sounds like Russia lost Angosat-1, a GEO commsat for Angola launched yesterday on Zenit.  Sounds like the Fregat tug got it to GEO, separated then things went south.

MOSCOW, December 27. / TASS /. With the Angolan satellite "Angosat", which was launched on December 26 from Baikonur, it was not possible to establish a connection. This was reported by a TASS source in the rocket and space industry.

 

"So far, there are no links with the" Angosat "satellite, we are dealing with the situation," the source said.

TASS does not have an official confirmation of this information.

The source of the agency added that communication with the satellite was lost at the stage of solar battery disclosure panel deployment. 

"After the division with the Fregat upper stage at 06:54 Moscow time everything was regular, the satellite's own orientation system was switched on, telemetry was fully applied, then the solar cells were opened, at this stage telemetry was lost," the source said.

Bummer for Angola (this would have been their first satellite) ... hopefully it is a temporary glitch and communications will be restored.  If not ... space is hard unfortunately.

It's a lot harder when you're launch provider suffers a series of solar panel deployment issues, from which Russia has been suffering for almost a decade. Particularly, this is been a problem on Progress and Soyuz missions.

 

It's a combination of an aging workforce where the young Engineers are heading for Europe or the US for better pay, and poor quality control.

Founds this video interesting.  A team at the University of Arizona explain how they create mirror glass for Chile's Giant Magellan Telescope, planned for completion in 2025.  The University has made around 20 mirror glasses for other telescopes, which is located under their football stadium.

Apparently all communications, telemetry, and command/control have been reestablished with Angosat-1. The satellite is reportedly in good health. Wow. Color me surprised.

He and Crippen were who I would consider to be the "Ultimate Team". Nobody else could have flown that first Shuttle flight with the same level of aptitude, grapefruits and sheer skill level as those two -- because that first Shuttle flight was so close to redline on so many instances that these two Astronauts were the only ones who could have dealt with it.

 

Young was also the Chief of the Astronaut Office from 1974 to 1987, being the longest-tenured Chief of that position. During STS-1's mission buildup and duration he was not required to relinquish that position as it would be his last flight, and training was relatively short.

 

He finally retired from NASA in 2004 at the age of 74, although he would still attend the monday morning briefings for years afterward. :) 

 

Hell of a guy, hell of an Astronaut.

Great Lakes bolide

 

Last night about 2008 Eastern time there was a very bright light, then an extremely bright flash followed by an enormous BOOM!! that shook the entire house. 

 

The local news channels were all over it saying it was seen as far away as Chicago,  massed about 1 metric tonne and it registered on seismographs as a 2.0 earthquake.

Saw this on the news, I guess a piece of it landed in a residential neighborhood in/near Taylor. We all saw the extremely bright light as it entered the atmosphere  ... how could anyone miss it?

 

I wanna know what its' composition/minerology is. :yes:

Cutting Bureaucracy To Meet Cape Canaveral's Aggressive Launch Goal

 

Cape laying groundwork for big boost in flight rate

Stepping Up to 48 [launches/year]

The way 45th Space Wing Commander Wayne Monteith sees it, the key to supporting 48 launches a year by 2020 is to remove bureaucratic obstacles such as having customers make reservations for range time at least six months in advance and to invest in new technologies, such as a graphic visualization system to sharpen the accuracy of launch-weather forecasts. 
>
>
Another system ripe for a technological reboot is the Space Wings scheduling tool, which literally consisted of a whiteboard. "Traditionally, if you wanted to get a launch slot on the range, you would plan somewhere between 6-36 months out to get your slot," Monteith says. "The new goal was 90 days, and now most of those requests come in under 60 days. My goal is to get that under 30 days, so a company like SpaceX can come in and say, I want to launch next month and if I have an opening, I want to be able to support that launch."

"They launch on readiness when they are ready to go they want to go," he adds. "Traditionally, we have launched on schedule. We've told our launch provider, 'This satellite will be ready in three years, and that's when you're going to launch. If you're ready early or if were ready early, that doesn't matter.' In order for us to bring business here to the Space Coast, we had to become much more agile and flexible and accommodating. The system has worked since the 1950s and 60s, but that doesn't mean it's going to work for the next 50 or 60 years. You have to adapt, or you become irrelevant."

Desire vs. Reality ... and getting the FAA and NASA to cooperate will be an entirely different thing. The FAA are going over everything with a fine-toothed comb, and NASA apparently feels the need to triple-check anything and everything that wants to fly out of the Cape ad nauseam before giving approval Which in if itself can take six months.

 

NASA will be the tough nut to crack on that one. FAA will be okay, I think.

      TWIRL 32: NASA preparing to launch Landsat 9 to observe Earth
      by Paul Hill



      We have several launches coming up over the next week. All of the missions on the schedule this week are satellite launches and among them the most interesting is NASA’s Landsat 9, an Earth observation satellite. The Landsat program currently has two satellites in orbit, Landsat 7 and Landsat 8 which launched in 1999 and 2013 respectively. The Landsat program itself has been up and running since July 1972.

      Monday, September 27
      The first launch of the week is ExPace’s Kuaizhou KZ-1A rocket carrying the Jilin Gaofen 2D satellite to Earth orbit. The launch is scheduled to take off from the Jiuquan Satellite Launch Center at 6:17 a.m. UTC. If you remember us covering this launch before, it’s because we have; this year, it has been pushed back from March, April, and September 25. It will take full-colour images with a resolution of 0.76 metres over 40 kilometres.

      The second launch of the day also take place in China but this time at the Xichang Satellite Launch Center. The launch of the Long March CZ-3B/E Is scheduled for an 8:15 a.m. UTC launch but it’s not clear what payload will be aboard. It’s rumoured that it could be launching a new generation of BeiDou (navigation) satellite.

      The third launch of the day takes place at 6:11 p.m. UTC from Vandenberg AFB Space Launch Complex 3. An Atlas V 401 rocket will carry the Landsat 9 satellite and several CubeSats into orbit. As mentioned earlier, the Landsat program started in 1972 and has tracked the growth of cities over that time, the changing climate, and how land is used for agriculture and infrastructure.

      The Landsat 9 satellite will be put into a polar orbit 705 kilometres above the Earth where it will survey the planet every 16 days. Images will cover 185km and each pixel will be 30 metres across. The satellite has been designed to last for five years but actually has enough fuel for the mission to go on for a decade or more.

      Friday, October 1
      The final mission of the week will take off from Uchinoura Space Center in Japan. An Epsilon rocket will be carrying the RAISE 2 satellite and several MicroSats. RAISE 2 is a demonstration satellite used for testing new technology in space. Among the MicroSats is the Debris Removal Unprecedented Micro-Satellite which will demonstrate technologies that future satellites need to remove the growing amount of space debris from orbit.

      Recap
      The exciting launch last week was that of the Tianzhou-3 module which was going to join on to the Chinese Space Station making station larger. The mission went ahead without a hitch, here’s the launch.

      And here’s the Tianzhou-3 docking.

      While three launches were scheduled last week, it looks like the Tianzhou-3 mission was the only one to get off the ground, so that’s all for this week’s recap.

    • Starlink could come out of beta next month despite pre-order backlog

      Starlink could come out of beta next month despite pre-order backlog
      by David Allen



      Starlink could be coming out of its beta testing phase and be made publicly available next month, Elon Musk says. With just over a year in beta, Starlink believes it has enough positive feedback to abandon the “beta” moniker. Most users in the year-long beta have reported positive feedback from the high-speed internet service alternative.

      The package consists of a Wi-Fi terminal and satellite dish in an automated self-install package costing $499. Service as of now is $99.00. Starlink has made every effort to make the service as price-friendly as possible, though challenges remain. Starlink is said to be working on a more rugged version of the device to better handle the weather elements.

      Those looking for a quick answer to a high-speed internet connection may have to keep waiting even after the service goes public. Recently, customers with pre-orders have seen fulfillment dates fall into 2022-2023 timeframes. It's estimated that Starlink already has approximately 400,000 preorders waiting to be filled.

      A service targeted for rural America and places where traditional broadband options don't exist, Starlink may offer a solid solution, but it sounds like users might be waiting a while to receive it. It'll be interesting to see how the service performs as more orders are filled.

      TWIRL 31: Chinese Space Station set to grow as Taikonauts return to Earth [Update]
      by Paul Hill



      In the upcoming week, China will launch a Long March rocket carrying Tianzhou 3 that will dock with the Tianhe module of the Chinese Space Station. The Tianzhou 3 will be carrying supplies up to the CSS for the next group of astronauts who go there and it will become a permanent fixture of the space station giving astronauts more space to roam around or store items.

      Monday, September 20
      There will be two launches to start off the week, the first is a Long March CZ-2C carrying three satellites with the designation Yaogan 30 Group 11. This mission, which launches from the Xichang Satellite Launch Center, is a little bit secretive. There’s no specific time for the launch and the mission of the satellites is not known, although, it is speculated that they could perform signals intelligence.

      The second launch of the day should take off between 7:00 a.m. and 8:00 a.m. UTC from the Wenchang Satellite Launch Center. A Long March CZ-7 will be carrying the Tianzhou 3 which will be itself carrying cargo for use aboard the Chinese Space Station. As mentioned before, this craft will make up part of China's space station allowing astronauts more room to move around. With every new module that joins the Chinese Space Station, the easier it should become to see from Earth too.

      Saturday, September 25
      The final launch on the schedule is an ExPace Kuaizhou KZ-1A rocket carrying more Jilin Gaofen 2D satellites. These satellites are part of the Jilin 1 Earth observation constellation and perform image captures in full colour at a resolution of 0.76 meters of 40km of surface area. In the end, the constellation will be made up of 138 satellites.

      Recap
      The first launch of the previous week took place on September 14 when a Falcon 9 rocket launched more Starlink satellites into orbit. Everything went to plan and the first stage landed back on a droneship in the Pacific Ocean.

      On the same day, a Starsem Soyuz 2.1b launched 34 OneWeb satellites into orbit from Kazakhstan. Like Starlink, OneWeb satellites beam internet back to Earth.

      Also this week, we had the launch of the Inspiration4 mission aboard a Falcon 9 rocket topped by a Dragon capsule. The launch went ahead without a hitch and the crew are still orbiting as of Friday, September 17.

      Finally, in the early hours of Friday (UTC), the Chinese astronauts came back down to Earth in a capsule slowed down by a parachute.

      Update: Since publication, the Inspiration4 crew have also landed back on Earth.

      by Paul Hill



      After a boring last two weeks in space launches, this week promises to be a lot more interesting. The main focus is the Inspiration4 Crew Dragon mission set to launch in the very early hours on Thursday (UTC, Wednesday local time) carrying pilot Jared Isaacman and three civilian astronauts; Hayley Arceneaux, Sian Proctor, and Chris Sembroski. Unlike Jeff Bezos’ trip to space, the Inspiration4 crew will stay in Earth orbit for several days before coming back to Earth.

      Monday, September 13
      The first launch of the week will come from SpaceX, which is launching a Falcon 9 Block 5 rocket from Vandenberg AFB. The rocket will carry 60 Block 1.5 Starlink satellites that are equipped with laser com terminals. The satellites will join the Starlink constellation and provide internet to subscribers on Earth. This launch should be available on the SpaceX website after it has taken place or as a live stream on its website during the event.

      The second launch will be a Long March CZ-2C taking off from the Jiuquan Satellite Launch Center. It will be carrying two satellites with the designation Yaogan 32 Group 02. It’s unclear what the purpose of the satellites is but they’re reportedly going to perform signals intelligence work. The launch was delayed from September 12 but hopes to launch at 7:45 a.m. UTC on the 13th.

      Tuesday, September 14
      On Tuesday, the private French-Russian company Starsem will launch a Soyuz 2.1b rocket with a Fregat upper stage carrying 34 OneWeb internet satellites to Earth orbit. This mission was delayed from August 26 and September 9 so, hopefully, the mission will succeed this time. OneWeb is a competitor to SpaceX and has already announced plans to beam internet to commercial flights and the Canadian military.

      Thursday, September 16
      On Wednesday evening, but Thursday morning (1:01 a.m.) on Universal Coordinated Time, we’ll see a SpaceX Falcon 9 Block 5 rocket take off from Florida carrying the Crew Dragon spacecraft containing a crew of four. The Inspiration4 mission will see pilot Jared Isaacman and three civilian astronauts spend about three days in Earth orbit before returning to Earth. Isaacman is joined on the mission by Hayley Arceneaux, Sian Proctor, and Chris Sembroski. When the crew comes back to Earth, they will splash down in the Atlantic Ocean near Cape Canaveral.

      Sunday, September 19
      The final mission of the week will launch from Jiuquan Satellite Launch Center. An ExPace Kuaizhou KZ-1A rocket will launch carrying the Jilin Gaofan 2F satellite. It will join the Jilin 1 Earth observation constellation which is run by Chang Guang Satellite Technology Company and is the 20th satellite to join the constellation. It will capture full-colour images down to 0.76 meters over a swath of 40km.

      Recap
      Last Tuesday at 3:01 a.m. UTC, a Long March 4C carrying the second Gaofen 5 satellite launched. It will be using instruments to observe the atmosphere and measure greenhouse gas emissions, trace gases, and more.

      On Thursday, a Long March 3B launched the Zhongxing 9B satellite into orbit to replace the Zhongxing 9A satellite. The satellite is used for telecommunication and will help provide radio, TV and other services in China, Hong Kong, Macau, and Taiwan.

      Also on Thursday, the Ministry of Defence of the Russian Federation launched a Soyuz 2.1v carrying the Kosmos-2551 satellite from the Plesetsk Cosmodrome. It will perform Earth observation tasks.

      TWIRL 29: China set to dominate launch schedule this week
      by Paul Hill



      The upcoming week won’t see any really exciting launches, just run-of-the-mill satellite launches. Interestingly, all the launches with a definite launch window will be launching from China. Launch sites seeing action this week include the Taiyuan Satellite Launch Center, the Xichang Satellite Launch Center, and the Jiuquan Satellite Launch Center.

      Monday, September 6
      The first launch of the week will see a Long March CZ-4C rocket carry the Gaofen 5-02 hyperspectral Earth-imaging satellite into orbit where it will make up part of the CHEOS constellation. The satellite will be carrying a number of scientific instruments that will allow it to perform atmospheric sensing to measure things like greenhouse gas emissions, trace gases and other atmospheric properties. This mission will launch from the Taiyuan Satellite Launch Center.

      Thursday, September 9
      The second launch of the week will take place at 11 a.m. UTC from the Xichang Satellite Launch Center. A Long March CZ-3B/E rocket will carry the Zhongxing 9B satellite into orbit. The satellite will provide various services such as TV and radio in China, Hong Kong, Macau, and Taiwan. The lifespan of the satellite is 15 years and it’ll support or replace the Zhongxing 9A satellite which used too much fuel trying to correct its position.

      Sunday, September 12
      The final launch of the week is due to take place from the Jiuquan Satellite Launch Center. A Long March CZ-2C rocket will be carrying two Yaogan satellites for the military. It’s unclear what the purpose of these satellites is.

      Recap
      Last Sunday, SpaceX’s CRS-23 mission managed to lift off following an earlier aborted launch.

      Not long after launch, the CRS-23 Dragon docked with the space station. It was carrying operational cargo for those aboard the ISS.

      The other rocket launch this week was Firefly Aerospace’s Alpha rocket which was performing its maiden flight. Unfortunately, the craft exploded not long after launch, destroying the numerous payloads that were aboard. The launch failure was put down to ‘an anomaly’.
