ULA interns launch record-breaking model rocket

The competition heats up: A team of ULA interns, working in their spare time, have successfully launched the largest model rocket every built.

On Sunday (July 24), ULA launched the 50-foot-tall (15.24 meters) Future Heavy rocket out of Fort Carson Army Post, breaking the record for “the largest sport rocket launched anywhere in the world,” according to a statement from ULA. The Future Heavy is also notable because it was built entirely by company interns and their mentors. “We like [our interns] to have a very realistic experience,” ULA President and CEO Tory Bruno told Space.com at the Space Symposium meeting in Colorado Springs, Colorado, last April.

Calling it a “model rocket” really isn’t fair. The thing is big, and really ranks up there with many of the suborbital rockets NASA used to routinely fly out of Wallops Island. That ULA has provided support for this effort again suggests that the leadership of Bruno is reshaping the company into a much more innovative and competitive company.

Two different kinds of boos

The American election process can be messy and entertaining, frightening and exhilarating, confusing and educational. In the past week we have had one great example of this during the nominating conventions of our two main political parties. In both cases, the convention-going party attendees have broken out in loud boos, loudly attacking people on the podium for their positions. Such behavior is not what you would expect from the modern conventions, which for several decades have been nothing more than staged propaganda events designed to sell their candidates to the American public. One doesn’t usually boo during such staged events.

First we had at the Republican convention the response to Ted Cruz’s speech, where when he refused to endorse Donald Trump he was almost literally driven from the stage by boos from the audience.

Then, yesterday we had Bernie Sanders supporters overwhelm the Democratic convention with boos, first during an appearance of former Democratic chairwoman Debbie Wasserman Schultz and then during the convention’s opening prayer.

It is important to understand the difference between these boos, as they are a strong marker of what will happen in November. In the case of the Republicans, the booing was in support of the Republican candidate, hostile to the implied opposition to Donald Trump by Ted Cruz. In the case of the Democrats, the booing was in opposition to the Democrat candidate, hostile to Hillary Clinton’s nomination and the perception that the Democratic Party stole the nomination from Bernie Sanders.

I have always believed that Hillary Clinton was the worst presidential candidate I have seen in my lifetime. It seems to me that this difference illustrates this fact once again. Sadly for me, the Republicans have wasted this opportunity and picked a liberal Democrat as their candidate, losing the best opportunity since 1980 to put an honest and principled conservative into office.

All I can do now is hope that Donald Trump will surprise me and be far more conservative than I expect, when he becomes President in January.

India faces $1 billion in damages for space contract cancellation

An arbitration court at the Hague yesterday ruled that India faces $1 billion in damages because of its unilateral cancellation in 2011 of a satellite deal between itself and a private company.

More info here. Essentially the ruling says that India had made a legal commitment when it signed the contract, and by unilaterally cancelled it they did harm to the private company’s shareholders.

This case illustrates that, despite India’s successes in space, it is still running a government space program, with all the flaws that come with it. Paying off these damages will likely put a serious crimp in the country’s space effort in the next few years.

Rosetta says goodbye to Philae

The Rosetta science team has decided to shut off tomorrow the communications equipment the spacecraft uses in its continuing attempts to re-establish communications with its Philae lander.

Switching off the ESS is part of the preparations for Rosetta’s end of mission. By the end of July 2016, the spacecraft will be some 520 million km from the Sun, and will start facing a significant loss of power – about 4W per day. In order to continue scientific operations over the next two months and to maximise their return, it became necessary to start reducing the power consumed by the non-essential payload components on board.

Though until now they have never stopped trying to contact Philae, they have heard nothing since July 2015. Moreover, the recent close sweeps down to the comet’s surface have failed so far to locate the lander. Unless they are holding back the lander’s discovery for a big splash press conference, it appears that we will never known exactly where the lander touched down.

That is, we will never know. Someday, many decades in the future, some asteroid/comet mining operation will show up and find it. I hope at that time they will carefully pack it up and bring it back for humans to admire as a testament to our human ability to push the unknown. Even better, I hope they put it in the “History of Space” museum, located not on Earth but on Mars, built to educate the children of the colonists who are making possible the expansion of humanity out to the stars.

More speculations about Trump’s cabinet

This article gives a nice overview of the people who it appears are being considered for positions in a Trump presidency, should he win.

Unfortunately, it does not give a lot of background about the people mentioned. Many, like Chris Christie, Jeff Sessions, Rudy Giuliani, and Newt Gingrich, are well known. Others, like businessman Donald McGahn, are unknown. Some, like Senator Bob Corker, suggested as potential Secretary of State, would be a disaster, based on his past history of getting the Iran deal approved.
Some. like Harold Hamm and Steve Mnuchin, have been described here at BtB at the links behind their names, Hamm positively and Mnuchin negatively..

There is more at the link. Read it all. This list is a start. It will require vetting to get a sense of what we can expect from a Trump administration.

Note that there is a reason I am so focused on Trump and not Clinton. Trump remains an unknown, who might be worth voting for if it appears his plans as President are reasonable, something that might still be possible, despite all the negative reports I’ve given him. Moreover, there is a chance that Trump can be positively influenced. Learning as much about him as possible increases that possibility.

Clinton however is not an unknown. She is corrupt, a liar, and an avowed socialist who believes strongly in increasing the size and power of the federal government, as does the entire political party that supports her. To deny any of this is to live with your head in the sand. She thus needs no vetting.

Trump considers funding super-PACs to defeat Cruz and Kasich in later elections

Update on the November Democratic primary: Donald Trump is considering creating two super-pacs expressly focused at destroying the political careers of Ohio Governor John Kasich and Texas Senator Ted Cruz.

During an event in Cleveland on Friday, Trump hinted at the prospect of funding an outside group against Cruz in the future.“Maybe I’ll set up a super-PAC if he decides to run,” Trump said of Cruz. Turning to his running mate Mike Pence he asked rhetorically, “Are you allowed to set up a super-PAC…if you are the president, to fight someone?”

The source close to Trump’s thinking indicated that Trump would consider forming the super-PAC whether or not he wins the presidential election in November.

This sure doesn’t sound like the actions of a Republican and conservative looking for allies within his party. Instead, it sounds like a Democrat who, having gotten the Republican nomination for President, can now stop pretending and begin the process of using his position to destroy the conservative movement in the United States in order to make it easier to impose liberal policies.

Trump’s supporters keep screaming that Cruz should have endorsed Trump for party unity. Well, the same applies to Trump — to bring the party together — only more so, since he has the nomination for president and as such is the de facto leader of the party. Moreover, while Cruz’s speech could have been more carefully worded, it nonetheless laid out the arguments for voting against Hillary Clinton and supporting all Republicans nationwide, even Trump (though unstated). Trump however is clearly doing the exact opposite, considering the investment of millions of his own money to actively work to defeat two of the party’s more conservative Republicans.

But hey, Trump can win! Who cares what he stands for!

Cruz’s speech at the convention

My first reaction to Ted Cruz’s exhortation that Republican’s vote their conscience in his speech at the Republican Convention last night was distress, as I expected the response to be mostly hostile (which it was) and unnecessary, as to my mind he could have gone there and simply said that “When Donald Trump becomes the next president I will be ready and waiting in the Senate to work with him to make sure the Constitution is defended and the federal government is brought under control.” Worded in this way, Cruz would not have been endorsing Trump, but he also would have not made himself an enemy of a significant percentage of the Republican voting bloc.

However, these two articles have changed my mind:

Cruz did the right thing. As noted at the first link,

If you’re voting for Donald Trump because you think he’s the lesser of two evils; because you think Hillary is clearly worse; because you reject leftism and know Hillary will foist leftism on us and only suspect Trump might . . . then you and I are cool. I respect that position. It’s not my position — but if it’s yours, I respect it, and I respect you.

But if you’re going to knock Ted Cruz for standing up against a man who bullied his family, I don’t respect you. I don’t want you here. Feel free to leave. It may make this place smaller, but it will make it better.

The second link also noted the unhealthy nature of today’s politics, where somehow one is not allowed to take a stand on conscience because of politics. Well to hell with that. There are things worth dying for, and one’s family is surely one of them.

Trump considers fracking businessman for Energy Secretary

Good news if true: Reuters today reported that presidential candidate Donald Trump is considering nominating Oklahoma businessman Harold Hamm as energy secretary if he wins the election.

In addition to considering Hamm, who has also functioned as Trump’s informal energy adviser in recent months, the article also noted this:

Trump, who has yet to make any announcements about his prospective cabinet, has already surrounded himself with strong advocates of traditional energy sources like oil, gas, and coal and has promised to gut environmental regulations to boost drilling and mining if elected. He tapped U.S. Congressman Kevin Cramer of North Dakota, a climate skeptic and drilling advocate, to help draw up his campaign energy platform, and picked Indiana Governor Mike Pence, also a climate skeptic, as his running mate.

Both moves cheered the energy industry but alarmed environmental activists who say a Trump presidency would set back years of progress on issues like pollution and climate change. “Given that Hamm’s as close as we’ve got to a fracker-in-chief in this country, it would be an apropos pick for a president who thinks global warming is a hoax manufactured by the Chinese,” said leading environmental activist Bill McKibben.

I keep saying it: Should Trump win, the best way we can guarantee that he favors conservative values is if he is surrounded by conservatives. These moves suggest that that Trump is agreeable to this, though there is also possibly a bit of some crony capitalism going on here as well. While these guys will likely advocate for less environmental regulations, I also doubt that they will work to eliminate the gobs of corporate welfare the federal government presently hands out.

No 6207 A Study in Steel

An evening pause: A fascinating and well-filmed documentary from 1935 describing how a British company then built locomotives. Note the lack of construction helmets, gloves, or safety glasses. Note also the number of workers involved. Today most of this work is automated, making it more precise and efficient. Then, however, they did not yet have such technology, and instead found ways to build very sophisticated machines using the skills of ordinary humans.

Hat tip Edward Thelen.

Trump will ask Congress to ease the firing of government workers

Good if true: According to New Jersey governor Chris Christie, who is in charge of Donald Trump’s transition team, should he win the presidency he will ask Congress to pass laws making it easier from him to fire government workers.

Trump’s transition advisers fear that Obama may convert these appointees to civil servants, who have more job security than officials who have been politically appointed. This would allow officials to keep their jobs in a new, possibly Republican, administration, Christie said. “It’s called burrowing,” Christie said. “You take them from the political appointee side into the civil service side, in order to try to set up … roadblocks for your successor, kind of like when all the Clinton people took all the Ws off the keyboard when George Bush was coming into the White House.”

Originally these laws were passed to reduce the spoils system, whereby new presidents got to hand out lots of jobs to friends once elected. Now, these laws merely act to prevent elected officials from having any supervisory oversight over the employees they manage.

The article also noted that the Trump campaign is beginning to assemble a list of government workers they want to fire should they win. This is also encouraging, considering the overall incompetence we’ve seen in the federal government these past few years. (I would especially like to see the entire management of the National Park Service fired for the part they played in helping Obama during the government shutdown.) It is time for a purge. If Trump follows through with this, it will be a very positive thing.

Expect a lot of squealing however from the usual suspects in Washington. The key will be whether Trump will have the courage to follow through despite those squeals.

Franky Zapata demonstrating his Flyboard Air

An evening pause: Hat tip t-dub, who wrote that the Flyboard Air “is a real product developed by Franky Zapata. It’s a jet powered board that reminds me of what the Green Goblin used in Spiderman. This video was done in Monaco during the Formula 1 race this year. His company is called Zapata Racing and he has developed a jet pack, water hover board, and those fire hose things people use over water which is a hydraulic Flyboard I believe. If they only had this stuff back in the 70’s when I was growing up.” T-dub also added, “The Flyboard can go up to 10,000 feet, fly at 98 MPH, and has a duration of almost ten minutes depending on use. They have also set a Guinness record with the device.”

My thought: Once again, life imitates art.

Reused Dragon cargo capsule to ISS within a year

The competition heats up: SpaceX hopes to launch a previously flown Dragon capsule to ISS sometime with the next year.

This fall, SpaceX plans to refly one of its landed Falcon 9 rockets for the first time — and a Dragon capsule should make history by launching on a repeat ISS resupply mission shortly thereafter, a NASA official and a SpaceX representative said during a postlaunch news conference Monday. “I think we’re looking at SpaceX-11,” said Joel Montalbano, NASA’s deputy manager of ISS utilization, referring to the 11th resupply mission the company will fly with Dragon and the Falcon 9. (Monday’s launch kicked off SpaceX-9.)

I had been wondering when SpaceX would try to reuse a Dragon, and had assumed the reason it hadn’t happened yet was partly because of NASA reluctance combined with the delays connected with the launch failure last year. Either way, it appears that NASA is now on board and that the company is beginning to gear up for that first reflight.

SpaceX seeks two more pads for returning 1st stages

The competition heats up: SpaceX is asking for permission to establish two more landing pads so that it will have the capability of landing three first stages all within minutes of each other.

“SpaceX expects to fly Falcon Heavy for the first time later this year,” the company said in a statement responding to questions. “We are also seeking regulatory approval to build two additional landing pads at Cape Canaveral Air Force Station. We hope to recover all three Falcon Heavy rockets, though initially we may attempt drone ship landings” at sea.

This news suggests two things: 1. The first Falcon Heavy launch is definitely coming soon. 2. They are going to try to return all three 1st stages during that first launch.

SpaceX chooses recovered first stage to reuse

The competition heats up: SpaceX has chosen as the first Falcon 9 first stage to reuse the one that was the first to land successfully on a barge on April 8.

Though they have not announced the mission it will fly, I strongly suspect it will be one of the two SES communications satellites scheduled to launch in the fall. SES has already said they want to buy a launch using a re-used first stage, and the two SES satellites scheduled for the fall have some redundancy between them.

Getting and Installing Linux – Part 4

The Software Manager

by James Stephens

A computer is nothing more than a toy unless it has the tools you need to get your work done, and Linux has a great set of tools. Most distributions come loaded with the tools most people use every day, a full office suite, graphics and media packages and so on. If you want more, a world of software awaits at your fingertips via the Software Manager. Think of it as the app store for your distribution, with tens of thousands of official titles vetted and available for download, most free of charge. No longer are you left to the wilds of the Internet to find what you need.

Most Linux Software is functionally equivalent to that of Apple or Windows. Most open source titles are ported to all platforms including Linux. So if you use an open source title such as Audacity or VLC media player, just type its name into the Linux Software Manager search bar and you will find it. For propitiatory titles such as Photoshop just define what it does, image manipulation for example, and the Software Manager will suggest Linux equivalents like GIMP or KRITA. In addition Photoshop and some other Windows software run great on Linux using WINE – the Windows compatibility layer. More about that later.

A brief history of the nuclear defence triad

Link here.

The essay is a fascinating look at the origins in the 1950s of the U.S.’s defense triad of ground-launched ICBMs, submarine-launched ICBMS, and bombers. The section on the history of ICBMs describes nicely the roots of the Atlas 5 rocket as well as many of the federal government’s contracting policies for its big government projects like SLS.

You can’t just call up a new weapons system from nothing by sheer will alone. As [Thomas Hughes, in his history of Project Atlas] explains, there were severe doubts about how one might organize such a work. The first instinct of the military was to just order it up the way they would order up a new plane model. But the amount of revolutionary work was too great, and the scientists and advisors running the effort really feared that if you went to a big airplane company like Convair and said, “make me a rocket,” the odds that they’d actually be able to make it work were low. They also didn’t want to assign it to some new laboratory run by the government, which they felt would be unlikely to be able to handle the large-scale production issues. Instead, they sought a different approach: contract out individual “systems” of the missile (guidance, fuel, etc.), and have an overall contractor manage all of the systems. This took some serious effort to get the DOD and Air Force to accept, but in the end they went with it. [emphasis mine]

Sounds remarkable like the way the SLS rocket program is organized, with different contractors building different engines and stages and one contractor (Boeing) acting as top manager. More interestingly, the way the military used to do things — put out a request and let the private sector build it — is similar to the way NASA is doing things in today’s commercial cargo/manned program. What forced the transition from having the private sector design things to having the government entirely in charge? I have highlighted the key phrase, “the scientists and advisors running the effort.” They might have been sincere and they might even have been right, at the time, but nonetheless their approach was still a power grab, taking control of design and construction from the private sector and shifting it to them and the government entities building the rockets.

When construction actually started, the government ended up with six different rocket programs, Redstone, Atlas, Thor, Titan, Polaris, and Minuteman.

The redundancy was a hedge: the goal was to pick the top two of the programs and cancel the rest. Instead, Sputnik happened. In the resulting political environment, Eisenhower felt he had to put into production and deployment all six of them — even though some were demonstrably not as technically sound as others (Thor and Polaris, in their first incarnations, were fraught with major technical problems). This feeling that he was pushed by the times (and by Congress, and the services, and so on) towards an increasingly foolish level of weapons production is part of what is reflected in Eisenhower’s famous 1961 warning about the powerful force of the “military-industrial complex.”

Once again, this history illustrates the power grab that took place in Washington in the 1950s, something that Eisenhower did not like. Sixty years later, the rocket industry is struggling to transition back to the old way of doing things, because it actually works better. Before the 1950s, our innovative, competitive, and fast moving technological private sector made the United States an unbeatable powerhouse. Afterward, we increasingly lost the ability to innovate and compete, because the system created by these scientists and advisors did not encourage competition. Instead, they instituted a top-down centralized command approach, ironically quite similar to the Soviet model, the very philosophy the United States was opposing during the Cold War.

The failures of that top-down approach — illustrated starkly by SLS’s gigantic budget, interminable delays, and little produced — might finally be coming home to roost, allowing a new power grab by a competitive private sector. The change I think will be generally beneficial, not only to the needs of the federal government but to the needs of the general population, as it will generate a lot more wealth, a lot more innovation, and a lot more excitement, as it once again makes the U.S. a powerhouse, this time out among the planets.

Freedom caucus demands impeachment vote on IRS head

Good news: Despite the opposition of Speaker Paul Ryan (R-Wisconsin), the conservative Freedom Caucus in the House is demanding a vote on the House floor on the impeachment of IRS head John Koskinen.

Two points: First, the vote is not guaranteed, as the motion put forth now will expire during the summer recess. The caucus will have to re-introduce it when Congress reconvenes in September, something they say they will do.

Second, Ryan’s resistance to having this vote does not speak well for him, considering the outrageous stonewalling by Koskinen in connection with IRS scandal, including lying to Congress and participating in the destruction of evidence that had been specifically requested by Congress. It also helps confirm the accusations of Ryan’s opponent in the August 9 Republican primary, Paul Nehlen, that Ryan is not the conservative he claims to be.

Trump picks Pence

It appears that Donald Trump has chosen Indiana governor Mike Pence as his vice presidential running mate.

This article provides a detailed look at Pence’s background, which is decidedly conservative and tightly linked with tea party philosophy.

Trump’s choice here is definitely encouraging. It suggests that his claimed conversion to conservative values might actually be sincere (though clearly shallow), because it suggests he is looking for conservatives to help him figure out how to be a conservative. As I’ve said repeatedly, the best way to make sure Trump governs as a constitutional conservative is to surround him with constitutional conservatives. This choice indicates that he is not going to resist that possibility.

Let me add that picking Pence could help Trump significantly in garnering support from the status quo Republicans that have been resisting him, since these same people respect Pence highly.

Let me also add one cautionary note. I have a memory of Pence at one point waffling on conservative principles for political gain, but I cannot at all remember the context or situation. Thus, it is important to remind ourselves repeatedly that these are all politicians, and that their interest is not necessarily that of the nation’s but of their own self-interest, which means getting elected. At any time they could toss the Constitution in the trash heap if that is what they think will get them votes. UPDATE: This article outlines Pence’s waffling as governor in Indiana, confirming my reservations about him.

It is therefore very important to not only surround Trump with conservatives, all politicians must be surrounded by voters who demand they defend our rights and our freedoms, as defined by the Constitution. Only then can we be reasonably assured that those rights will be defended.

DARPA pushes its Experimental Spaceplane program forward

The competition heats up: DARPA outlines its goals for its Experimental Spaceplane program (XS-1).

Key to the effort is DARPA’s recognition that since 2000 under the government’s EELV program, launch costs for the military had increased significantly, while the launch rates appears to slow.

According to DARPA’s presentation, the Pegasus, Minotaur, and Antares launch vehicles only fly one DoD mission per year at a cost of ~$55 million USD per flight.

SpaceX’s Falcon 9 currently performs ~3-6 DoD missions per year at a contract price equal to or greater than $54 million USD per flight.

That price per flight then jumps dramatically for United Launch Alliance’s (ULA’s) Atlas V and Delta IV launch vehicle families – which currently perform about 8 DoD flights per year for a cost per flight in excess of $400 million USD. [emphasis mine]

ULA claims that they charge the Air Force an average of $225 million per launch. DARPA says it is $400 million. Either way, that is a lot higher than the $83 million that SpaceX charged for its first Air Force contract.

The article then provides a nice overview of the XS-1 program, which like NASA’s commercial space program is asking private companies to come up with the new designs and technologies rather than have the government try to do it. All DARPA is doing is laying out their basic requirements, fly 10 times in 10 days for less than $5 million per flight.

The program is now shifting to its second phase, which will call for actual construction proposals late this year, with the hope of test flights by 2019.

Iridium’s next generation constellation of satellites

The competition heats up: Iridium prepares the first 10 of a total of 81 new satellites for launch on SpaceX’s Falcon 9 in September.

The Iridium Next program is a $3 billion investment by Iridium, according to Matt Desch, Iridium’s chief executive officer. Iridium’s purchase of 81 satellites represents approximately $2.2 billion of that cost, Desch said, and the company’s launch contract with SpaceX for seven Falcon 9 flights was valued at $492 million when the parties signed it in 2010. That was the largest commercial launch contract in history until last year’s 21-launch order by satellite Internet provider OneWeb with Arianespace.

The first 10 Iridium Next satellites will fly on a Falcon 9 rocket in September, followed by a second launch as soon as December with the next batch. Iridium managers will give the go-ahead for the second launch once the first 10 satellites finish initial in-orbit tests, Desch said. The other five launches should occur about once every two months next year to fill out the Iridium Next fleet 485 miles (780 kilometers) above Earth. Iridium’s contract with SpaceX calls for all the missions to fly on newly-built Falcon 9s, a situation unlikely to change any time soon since insurance arrangements for the initial launches have been finalized.

But Desch said he is open to purchasing reused Falcon 9 boosters in the future “if they’re the right price.”

To meet this schedule SpaceX’s launch schedule will have to ramp up considerably from its present rate of one launch about every three weeks.

Privately built smallsat designed deep space communications

The competition heats up: A partnership between two British space companies, a smallsat manufacturer and a space antenna operator, will team up to build and test a new smallsat communications satellite in lunar orbit.

The SSTL-GES Lunar Pathfinder team are already working on the initial baseline design, with technical assistance from the European Space Agency (ESA). SSTL are designing a series of lunar communication satellites and will be building on their heritage of small satellite platforms in Low Earth orbit and Medium Earth orbit to go beyond Earth’s orbit for the first time. GES are upgrading one of the famous antennas at their Goonhilly site in Cornwall, UK, into a deep space ground asset, which will be the first element in a commercial deep space network. In addition, GES will provide a dedicated mission operations centre situated in Cornwall.

What is interesting about this is that this is a private effort to develop a modern commercial deep space communications network for future planetary missions. It would be competitive with NASA’s Deep Space Network, which presently is the only game in town and is generally made up of upgraded 1960s based technology. This new network would also eventually include a dedicated network of smallsats scattered through the solar system to act as communications relays. This is something that NASA does not provide, depending instead on the communications instruments of the planetary missions themselves.

Rocket Lab gets new launch contract

The competition heats up: Rocket Lab has signed a three launch contract with the smallsat Earth resources satellite company Planet (formerly Planet Labs).

The contract covers three dedicated launches of Dove satellites built by San Francisco-based Planet, formerly known as Planet Labs, on Electron vehicles. The companies did not announce terms of the deal, although Rocket Lab quotes a list price of $4.9 million per Electron launch on its website.

Mike Safyan, director of launch and regulatory affairs for Planet, said in an interview during the International Space Station Research and Development Conference here that the number of satellites that each launch will carry is still being determined, but will likely be between 20 and 25. Each Dove is a three-unit cubesat with a mass of about five kilograms.

If this report as well as previous ones are correct, the first Electron rocket launch will happen before the end of this year.

Breakthrough on battery life?

New research might have discovered engineering that could significantly increase the efficiency of the batteries we use.

This is where Mya Le Thai’s magic gel comes in. Typically, a Lithium Ion battery can go through between 5000 and 7000 recharge cycles before it dies and will also gradually lose its energy storage capacity over time. When researchers applied Thai’s plexiglass-like gel to gold nanowires in a manganese dioxiode shell, it increased that number to over 200,000 and the battery didn’t lose any of its power or storage capacity over a period of three months.

Sierra Nevada completes first Dream Chaser milestone

The competition heats up: Even as it prepares to complete the last milestone in its NASA contract for developing a manned version of Dream Chaser, Sierra Nevada has just completed the first milestone on its contract to build a cargo version of the reusable lifting body spaceplane.

Though Sierra Nevada did not win a contract to build the manned Dream Chaser, it did have a development contract with NASA that called for one more glide flight test, a test the company had until now decided not to fly because the cost would exceed the milestone payment. This changed however after they won a cargo contract, as the flight will provide important test data for building the cargo version.

Meanwhile, the company’s plan for building the cargo vehicle has been approved by NASA, thus rewarding them their first milestone on that contract, with the following schedule:

Per current schedule goals, Mr. Olson added the inaugural Dream Chaser cargo flight to ISS is aiming for a launch – on the United Launch Alliance Atlas V – as early as October 2019, or as late as April 2020. The company is aiming to build two Dream Chasers, able to fly a total of 30 times over a 10 year lifetime.

Once built and successfully flying, they also plan to move forward on developing the manned version, both for NASA and for others.

Cubesats to the planets!

Link here. The article is a good detailed overview of the many upcoming planetary missions that are using small and relatively inexpensive cubesats as either part of their mission, or are the mission itself.

This trend also partly explains the number of new rocket companies like Rocket Lab and Firefly Space Systems that are developing small rockets aimed at launching cubesats. These companies have recognized a growing demand, and are trying to serve it. As the article notes,

Lifts are so hard to come by that the first interplanetary CubeSat — NASA’s twin INSPIRE mini-spacecraft, intended to test key technology for future missions — has been waiting for almost two years. “We still have to find a ride,” says Anthony Freeman, who manages the Innovation Foundry at NASA’s Jet Propulsion Laboratory in Pasadena, California.
