SpaceX called off the much-delayed inaugural launch of their new Falcon 1 rocket on Saturday from Kwajalein’s Omelek Island launch site. The intent was to launch the U.S. Air Force Academy’s FalconSat 2 satellite, which will monitor plasma interactions with the Earth’s upper atmosphere and magnetosphere.

The launch was delayed, then finally cancelled after an oxygen boil-off vent had accidentally been left open. The oxygen was unable to cool the helium pressurant, which then proceeded to evaporate faster than it could be replenished. A main computer issue, probably serious enough to cause a scrub on its own, was also discovered.

This long-anticipated flight was originally expected to be launched in January 2005, however a series of setbacks forced a series of delays, with the flight most recently scheduled to be in early 2006. It was intended to be launched from the Kwajalein atoll in the middle of the Pacific Ocean.

The maiden voyage was originally intended to launch from Vandenberg Air Force Base in California with a Naval Research Laboratory satellite and a Space Services Incorporated space burial payload.

Businessman Rocky De La Fuente took some time to speak with Wikinews about his campaign for the U.S. Democratic Party’s 2016 presidential nomination.

The 61-year-old De La Fuente resides in San Diego, California, grew up in Tijuana, and owns multiple businesses and properties throughout the world. Since getting his start in the automobile industry, De La Fuente has branched out into the banking and real estate markets. Despite not having held or sought political office previously, he has been involved in politics, serving as the first-ever Hispanic superdelegate to the 1992 Democratic National Convention.

De La Fuente entered the 2016 presidential race last October largely due to his dissatisfaction with Republican front-runner Donald Trump. He argues he is a more accomplished businessman than Trump, and attacks Trump as “a clown,” “a joke,” “dangerous,” and “in the same category as Hitler.” Nevertheless, De La Fuente’s business background begets comparisons with Trump. The Alaskan Midnight Sun blog described him as the Democrats’ “own Donald Trump.”

While receiving only minimal media coverage, he has campaigned actively, and according to the latest Federal Election Commission filing, loaned almost US$ 4 million of his own money to the campaign. He has qualified for 48 primary and caucus ballots, but has not yet obtained any delegates to the 2016 Democratic National Convention. Thus far, according to the count at The Green Papers, De La Fuente has received 35,406 votes, or 0.23% of the total votes cast. He leads among the many lesser-known candidates but trails both Senator Bernie Sanders who has received nearly 6.5 million votes and front-runner Hillary Clinton who has just shy of 9 million votes.

With Wikinews reporter William S. Saturn?, De La Fuente discusses his personal background, his positions on political issues, his current campaign for president, and his political future.

A 182-page report issued September 1 by the United States National Research Council warns that the amount of debris in space is reaching “a tipping point”, and could cause damage to satellites or spacecraft. The report calls for regulations to reduce the amount of debris, and suggests that scientists increase research into methods to remove some of the debris from orbit, though it makes no recommendations about how to do so.

NASA sponsored the study.

A statement released along with the report warns that, according to some computer models, the debris “has reached a tipping point, with enough currently in orbit to continually collide and create even more debris, raising the risk of spacecraft failures”. According to the Satellite Industry Association, there are now about 1,000 working satellites in Earth orbit, and industry revenues last year were US$168 billion (£104.33 billion,€119.01 billion).

The debris consists of various objects, such as decommissioned satellites and exhausted boosters, but the vast majority of the particles are less than one centimetre across. 16,094 pieces of debris were being tracked as of July, although estimates put the current number at over 22,000. The total number of fragments is thought to be as high as tens of millions. While most of the debris is very small, some of it is travelling at speeds as high as 17,500 mi h^-1 (28,164 km h^-1; 7,823.3 m s^-1).

The International Space Station sometimes has to dodge larger fragments, and in June its crew was forced to prepare to evacuate due to a close encounter with debris.

The UK Space Agency told Wikinews that space flight “is likely to be made more difficult” by the debris. However, communications will “[n]ot directly” be affected, “but if the GEO ring became unusable, there is no other altitude at which objects appear [‘]geo-stationary[‘] and so all antennas on the ground would then have to move in order to track the motion of the satellites”.

Donald J. Kessler, the lead researcher and former head of NASA’s Orbital Debris Program Office, said that “[t]he current space environment is growing increasingly hazardous to spacecraft and astronauts,” and suggested that “NASA needs to determine the best path forward for tackling the multifaceted problems caused by meteoroids and orbital debris that put human and robotic space operations at risk.”

Two events are thought to be the largest individual sources of space debris. Kessler said that “[t]hose two single events doubled the amount of fragments in Earth orbit and completely wiped out what we had done in the last 25 years”.

The first of these was a controversial 2007 Chinese anti-satellite weapon test, which smashed the decommissioned weather satellite Fengyun-1C into approximately 150,000 fragments over a centimetre in size—making up roughly twenty percent of all tracked objects—537 miles above the Earth’s surface.

The Chinese government has so far failed to respond to Wikinews’s queries regarding the incident.

The other is a 2009 collision between twelve-year-old active satellite Iridium 33 and the defunct Russian Strela-2M satellite Kosmos-2251—both weighing in excess of 1,000 lbs (454 kg)—that occurred 490 miles over Siberia, the first such collision. The Iridium satellite was replaced within 22 days, according to Iridium Communications, who operated it.

In a statement released to Wikinews, Iridium Communications said that they “received no warning of the impending collision. Although commercial projections of close encounters (commonly called conjunctions) were available, the accuracy of those projections was not sufficient to allow collision avoidance action to be taken.” They also made the assurance that the Air Force Space Command and United States Strategic Command now provide them with information through the Joint Space Operations Center, and that “when necessary, [they] maneuver [their] satellites based on this information to avoid potential collisions. [They] believe this is a substantial first step in better information sharing between the government and industry and support even more robust interaction which can provide better and more efficient constellation operation.”

Iridium expressed their support for “[l]ong-term investment to improve Space Situational Awareness” and “[i]mproved information sharing between industry and the U.S. government”, as well as more “[g]overnment support for policy and processes which would permit sharing of high-accuracy data as required to allow reliable assessment and warning” and “[i]ncreased cooperation between the government and U.S. and foreign commercial operators.”

They maintained that “the Iridium constellation is uniquely designed to withstand such an event. Because of the resilient and distributed nature of the Iridium constellation, the effects of the loss of a single satellite were relatively minor”, and that “any other system, commercial or military, which experienced the loss of a satellite, would have suffered significant operational degradation for a period of months if not years.” Nonetheless, the company is “concerned over the increasing level of risk to operations resulting from the debris in space.”

The report makes more than thirty findings, and more than twenty recommendations to NASA. None of the recommendations regard how to clean up the debris. However, it does cite a report by the Defense Advanced Research Projects Agency (DARPA), which suggested various possible techniques for catching and removing space debris, such as magnetic nets.

However, international law does not allow one country to collect another’s debris. George J. Gleghorn, vice chair of the committee, observed that “[t]he Cold War is over, but the acute sensitivity regarding satellite technology remains”.

The debris will, in time, be pulled into the earth’s atmosphere—where it will burn up—by gravity, but more debris is being created faster than this can happen.

The report recommends collaborating with the United States Department of State on “economic, technological, political, and legal considerations.” As already mentioned, international law does not allow one country to collect another’s debris.

According to the report, “[t]he problem of space debris is similar to a host of other environmental problems and public concerns characterized by possibly significant differences between the short- and long-run damage accruing to society … Each has small short-run effects but, if left unaddressed, will have much larger impacts on society in the future.”

A spokesperson for the UK Space Agency told Wikinews that the organisation “does not have any plans to get directly involved with [the clean-up] initiative but through its involvement with NASA in the Inter-Agency Space Debris Coordination Committee, it is conducting studies to identify which objects present the biggest hazard and how many objects may need to be removed and from where.” It says that the viability of such an operation is “a question of treating the symptom or the cause of the problem. Building more physical protection is costly and if the environment deteriorates too far, becomes unviable. It is best to treat the root cause, the presence of debris in orbit, and remove the large objects before they can break up into many thousands of uncontrolled fragments capable of destroying a satellite on impact.”

The spokesperson also pointed out that “[u]nder current licensing regimes (such as in the UK), countries are now obliging operators to remove satellites from crowded regions of space at the end of operational life”.

A 54-year-old German farmer who lost both arms in a farming accident six years ago has become the first patient to receive a complete double arm transplant. The patient, whose name has not been released, underwent the operation at the Klinikum rechts der Isar, part of the Technical University of Munich (Technische Universität München), last week; he is said to be recovering well.

The operation lasted 15 hours and was performed by a team of 40 specialists in Plastic Surgery, Hand Surgery, Orthopedics and Anesthesiology, under the direction of the head of the Plastics and Hand Surgery department, Prof. Hans-Günther Machens, Dr. Christoph Höhnke (Head of Transplants, Senior Physician; Plastics and Hand Surgery) and Prof. Edgar Biemer, the former Chief of Plastic Surgery at the Clinic.

In a press statement released by the clinic, it was revealed that the patient had been thoroughly physically checked and had psychological counselling prior to the surgery to ensure he was mentally stable enough to cope with the procedure. Since completion of the surgery, the patient has been on immuno-suppressant drugs to prevent rejection of the new limbs.

Following the surgery, the press release from the clinic’s press manager, Dr. Tanja Schmidhofer, included the following statement:

Without the immuno-suppressant drugs given to the patient, the risk of there being a Graft-versus-Host Reaction or GvHR, would have been significant due to the upper arm containing a large amount of bone marrow, consisting of ICC’s or Immuno-Competent Cells, which would have triggered a near total rejection of the new limbs. A GvHR is a condition which results in the cells from the transplant attacking the immune system of the body.

Indications from the clinic suggest that the double attachment went well, although it could be up to 2 full years before the patient is able to move the arms.

The donor arms came from an unnamed teenager, who is believed to have died in a car accident.

Wikinews reporter David Shankbone is currently, courtesy of the Israeli government and friends, visiting Israel. This is a first-hand account of his experiences and may — as a result — not fully comply with Wikinews’ neutrality policy. Please note this is a journalism experiment for Wikinews and put constructive criticism on the collaboration page.

Dr. Yossi Vardi is known as Israel’s ‘Father of the Entrepreneur’, and he has many children in the form of technology companies he has helped to incubate in Tel Aviv‘s booming Internet sector. At the offices of Superna, one such company, he introduced a whirlwind of presentations from his baby incubators to a group of journalists. What stuck most in my head was when Vardi said, “What is important is not the technology, but the talent.” Perhaps because he repeated this after each young Internet entrepreneur showed us his or her latest creation under Vardi’s tutelage. I had a sense of déjà vu from this mantra. A casual reader of the newspapers during the Dot.com boom will remember a glut of stories that could be called “The Rise of the Failure”; people whose technology companies had collapsed were suddenly hot commodities to start up new companies. This seemingly paradoxical thinking was talked about as new back then; but even Thomas Edison—the Father of Invention—is oft-quoted for saying, “I have not failed. I have just found ten thousand ways that won’t work.”

Vardi’s focus on encouraging his brood of talent regardless of the practicalities stuck out to me because of a recent pair of “dueling studies” The New York Times has printed. These are the sort of studies that confuse parents on how to raise their kids. The first, by Carol Dweck at Stanford University, came to the conclusion that children who are not praised for their efforts, regardless of the outcome’s success, rarely attempt more challenging and complex pursuits. According to Dweck’s study, when a child knows that they will receive praise for being right instead of for tackling difficult problems, even if they fail, they will simply elect to take on easy tasks in which they are assured of finding the solution.

Only one month earlier the Times produced another story for parents to agonize over, this time based on a study from the Brookings Institution, entitled “Are Kids Getting Too Much Praise?” Unlike Dweck’s clinical study, Brookings drew conclusions from statistical data that could be influenced by a variety of factors (since there was no clinical control). The study found American kids are far more confident that they have done well than their Korean counterparts, even when the inverse is true. The Times adds in the words of a Harvard faculty psychologist who intoned, “Self-esteem is based on real accomplishments. It’s all about letting kids shine in a realistic way.” But this is not the first time the self-esteem generation’s proponents have been criticized.

Vardi clearly would find himself encouraged by Dweck’s study, though, based upon how often he seemed to ask us to keep our eyes on the people more than the products. That’s not to say he has not found his latest ICQ, though only time—and consumers—will tell.

For a Web 2.User like myself, I was most fascinated by Fixya, a site that, like Wikipedia, exists on the free work of people with knowledge. Fixya is a tech support site where people who are having problems with equipment ask a question and it is answered by registered “experts.” These experts are the equivalent of Wikipedia’s editors: they are self-ordained purveyors of solutions. But instead of solving a mystery of knowledge a reader has in their head, these experts solve a problem related to something you have bought and do not understand. From baby cribs to cellular phones, over 500,000 products are “supported” on Fixya’s website. The Fixya business model relies upon the good will of its experts to want to help other people through the ever-expanding world of consumer appliances. But it is different from Wikipedia in two important ways. First, Fixya is for-profit. The altruistic exchange of information is somewhat dampened by the knowledge that somebody, somewhere, is profiting from whatever you give. Second, with Wikipedia it is very easy for a person to type in a few sentences about a subject on an article about the Toshiba Satellite laptop, but to answer technical problems a person is experiencing seems like a different realm. But is it? “It’s a beautiful thing. People really want to help other people,” said the presenter, who marveled at the community that has already developed on Fixya. “Another difference from Wikipedia is that we have a premium content version of the site.” Their premium site is where they envision making their money. Customers with a problem will assign a dollar amount based upon how badly they need an answer to a question, and the expert-editors of Fixya will share in the payment for the resolved issue. Like Wikipedia, reputation is paramount to Fixya’s experts. Whereas Wikipedia editors are judged by how they are perceived in the Wiki community, the amount of barnstars they receive and by the value of their contributions, Fixya’s customers rate its experts based upon the usefulness of their advice. The site is currently working on offering extended warranties with some manufacturers, although it was not clear how that would work on a site that functioned on the work of any expert.

Another collaborative effort product presented to us was YouFig, which is software designed to allow a group of people to collaborate on work product. This is not a new idea, although may web-based products have generally fallen flat. The idea is that people who are working on a multi-media project can combine efforts to create a final product. They envision their initial market to be academia, but one could see the product stretching to fields such as law, where large litigation projects with high-level of collaboration on both document creation and media presentation; in business, where software aimed at product development has generally not lived up to its promises; and in the science and engineering fields, where multi-media collaboration is quickly becoming not only the norm, but a necessity.

For the popular consumer market, Superna, whose offices hosted our meeting, demonstrated their cost-saving vision for the Smart Home (SH). Current SH systems require a large, expensive server in order to coordinate all the electronic appliances in today’s air-conditioned, lit and entertainment-saturated house. Such coordinating servers can cost upwards of US$5,000, whereas Superna’s software can turn a US$1,000 hand-held tablet PC into household remote control.

There were a few start-ups where Vardi’s fatherly mentoring seemed more at play than long-term practical business modeling. In the hot market of WiFi products, WeFi is software that will allow groups of users, such as friends, share knowledge about the location of free Internet WiFi access, and also provide codes and keys for certain hot spots, with access provided only to the trusted users within a group. The mock-up that was shown to us had a Google Maps-esque city block that had green points to the known hot spots that are available either for free (such as those owned by good Samaritans who do not secure their WiFi access) or for pay, with access information provided for that location. I saw two long-term problems: first, WiMAX, which is able to provide Internet access to people for miles within its range. There is already discussion all over the Internet as to whether this technology will eventually make WiFi obsolete, negating the need to find “hot spots” for a group of friends. Taiwan is already testing an island-wide WiMAX project. The second problem is if good Samaritans are more easily located, instead of just happened-upon, how many will keep their WiFi access free? It has already become more difficult to find people willing to contribute to free Internet. Even in Tel Aviv, and elsewhere, I have come across several secure wireless users who named their network “Fuck Off” in an in-your-face message to freeloaders.

Another child of Vardi’s that the Brookings Institution might say was over-praised for self-esteem but lacking real accomplishment is AtlasCT, although reportedly Nokia offered to pay US$8.1 million for the software, which they turned down. It is again a map-based software that allows user-generated photographs to be uploaded to personalized street maps that they can share with friends, students, colleagues or whomever else wants to view a person’s slideshow from their vacation to Paris (“Dude, go to the icon over Boulevard Montmartre and you’ll see this girl I thought was hot outside the Hard Rock Cafe!”) Aside from the idea that many people probably have little interest in looking at the photo journey of someone they know (“You can see how I traced the steps of Jesus in the Galilee“), it is also easy to imagine Google coming out with its own freeware that would instantly trump this program. Although one can see an e-classroom in architecture employing such software to allow students to take a walking tour through Rome, its desirability may be limited.

Whether Vardi is a smart parent for his encouragement, or in fact propping up laggards, is something only time will tell him as he attempts to bring these products of his children to market. The look of awe that came across each company’s representative whenever he entered the room provided the answer to the question of Who’s your daddy?
