Scientists are monitoring a defunct Chinese space station that is expected to fall to Earth around the end of the month, the largest manmade object to re-enter Earth’s atmosphere in a decade.

The head of the European Space Agency’s debris office, Holger Krag, says China’s Tiangong-1 space station will likely fall to Earth between March 30 and April 3.

Krag said it still not yet known where the space station will hit Earth, but said it would be extremely unlikely for anyone to be injured when it does.

Injury unlikely

“Our experience is that for such large objects typically between 20 and 40 percent of the original mass, of 8.5 tons, will survive re-entry and then could be found on the ground, theoretically,” he said.

“However, to be injured by one of these fragments is extremely unlikely. My estimate is that the probability to be injured by one of these fragments is similar to the probability of being hit by lightning twice in the same year,” Krag added.

He said the space station is expected to fall between the areas of 43 degrees south and 43 degrees north, and everything outside that zone is considered safe.

“Northern Europe including France, Germany, Austria and Switzerland are definitely on the safe side. Southern Europe, the southern part of North America, South Asia, Africa, Australia and also South America are still within the zone today,” he said.

Where will it hit?

Scientists say it is hard to predict where Tiangong-1 will hit Earth in part because of its low orbit and high velocity. They say the space station is traveling 17,400 mph and orbits Earth about every 90 minutes.

Tiangong-1 was launched into orbit in 2011 as China’s first space lab. It carried out orbit experiments in preparation for China’s plan to put a permanent space station into orbit by 2023.

What does it take to build a thriving technology company – and an environment in which black techies, their financial backers and their markets can flourish?

That question underpins the new VOA documentary “Beyond the Unicorn.”  Subtitled “Africans Making IT in Silicon Valley,” it explores how some Africans and African-Americans are finding their way in the tech sector’s global capital in California.

The 26-minute documentary profiles several entrepreneurs and venture capitalists and how they overcome hurdles. Its screening Wednesday evening, at a VOA event at the San Francisco campus of the French university INSEEC U., served as a springboard for a panel discussion spanning market potential, funding gaps and hiring disparities.

First, a definition for the uninitiated. A unicorn is a private startup technology firm valued at $1 billion or more. Once rare, such companies have proliferated in the last few years, with almost 200 globally as of last May, according to Forbes.

Silicon Valley has spawned herds of unicorns, such as Uber and Airbnb.  

Africa hasn’t. With less readily available investment funding, “a unicorn might be quite unrealistic for an entrepreneur in Africa to build very quickly,” said venture capitalist Mbwana Alliy, who appears in the documentary. He suggested its counterpart might be a “zebracorn.”           

“Does that mean it’s a $100 million startup? Maybe that’s more achievable for an entrepreneur,” said Alliy, founder of the Africa-focused Savannah Fund. “And it’s still a major outcome.”   

Panelist Stephen Ozoigbo proposed another term: gazelle, “something real and indigenous.”

“If it’s a gazelle, then you’re sure it would outrun, it would outhustle” the competition, said Ozoigbo, CEO of the African Technology Foundation.   

​Market potential

The continent has some fast-growing economies – think Ethiopia and Nigeria – and the world’s fastest-growing population. More than half of its countries are expected to double their head counts by 2050, the United Nations reports.

No wonder investment in African tech ventures is surging.

Figures vary: The Disrupt Africa news portal says African tech startups raised more than $195 million last year, up from almost $130 million in 2016.

Partech Ventures reports even stronger growth. The global venture capital firm, which has offices in San Francisco and Dakar, Senegal, reports that 124 tech startups drew $560 million in equity in 2017, up from almost $367 million for 74 startups the previous year.

Still, Africa gets only a very tiny share of global private equity capital, said Andile Ngcaba, a panelist and founder of the African tech investment management fund Convergence Partners.

That’s just one of the challenges for Africans and African-Americans in tech.

Lack of diversity

Blacks account for just 3 percent of the workforce among Silicon Valley’s top 75 tech companies, an underrepresentation so striking that it has drawn public condemnation and scrutiny by the U.S. Equal Employment Opportunity Commission in a 2016 report.

The male-dominated tech sector can be even less welcoming to black females.

“Being an African woman in Silicon Valley … has been very difficult. I actually had an easier time in Nigeria,” said Bukola Akinfaderin, a senior developer – and the only black female mobile engineer – for the genealogy website Ancestry.com. She said her homeland’s tech sector has less of a gender imbalance.

Akinfaderin, featured in the documentary, finds support in groups such as dev/color, a nonprofit for black software engineers.

She gets encouragement to revive Jandus Radio, her app enabling the African diaspora to hear live radio from the continent. It had as many as 500,000 users by 2016, when the hosting company’s server malfunctioned and deleted the app’s database. She plans to reboot the app as KinFolk.

Akinfaderin touts the value of being an African woman engineer working in Silicon Valley. “When you’re building a product – especially if it’s a consumer-facing product, one that’s international – you are going to need perspective from everyone.”

Need for helping hands

Mentoring and networking can make all the difference in finding opportunities, said Nate Yohannes, a Microsoft business development director for artificial intelligence – and the evening’s keynote speaker.

“Coming to the United States as a child of [Eritrean] refugees,” he said, he couldn’t always rely on his parents’ guidance because of their unfamiliarity with the new setting. So, he sought out mentors, who helped shape his trajectory from law school to a Wall Street job to the U.S. Small Business Association to Microsoft.

“It’s on us” to help each other and connect the continents, Yohannes told the scores of people, including other Africans, in the screening room.

Other concerns

Africa’s rapid population growth heightens the need to educate African youths so they can compete for work globally, said Convergence Partners’ Ngcaba. He added that those aspiring to the tech sector will need training in, say, data science, machine learning and artificial intelligence.

“That’s the only way we can position ourselves in the global landscape,” Ngcaba said.

Skills, opportunity and capital are vital for entrepreneurs, agreed Yonas Beshawred, founder and CEO of StackShare, an online marketplace for comparing engineering tools and software.

But, he added, “I think the most important thing is that you have something that you’re passionate about and you start working on it … instead of just talking.”

A VOA showcase

The “Unicorn” screening event also served as a showcase for VOA’s commitment to “telling America’s story” along with providing accurate news and information to countries without independent media, VOA director Amanda Bennett said. 

“And what is more American than the American diaspora, the people who come here from places around the world looking for something and looking to give something, looking to be someone? And what is more American than technology?” she asked rhetorically in her introductory remarks, pointing out that VOA opened a Silicon Valley office last spring.

The semi-government agency behind India’s national identity card project on Saturday denied a report by news website ZDNet that the program has been hit by another security lapse that allows access to private information.

ZDNet reported that a data leak on a system run by a state-owned utility company, which it did not name, could allow access to private information of holders of the biometric “Aadhaar” ID cards, exposing their names, their unique 12-digit identity numbers and their bank details.

But the Unique Identification Authority of India (UIDAI), which runs the Aadhaar program, said “there is no truth in this story” and that it was “contemplating legal action against ZDNet.”

ZDNet could not immediately be contacted for comment on the UIDAI’s response.

“There has been absolutely no breach of UIDAI’s Aadhaar database. Aadhaar remains safe and secure,” the agency said in a statement late Saturday.

Even if the claim purported in the story were taken as true, it would raise security concerns about the database of the utility company and would have “nothing to do with the security of UIDAI’s Aadhaar database,” it said.

More than 1 billion users

ZDNet had reported that even though the security lapse was flagged to some government agencies over a period of time, it had yet to be fixed. It said it was withholding the name of the utility and other details.

Karan Saini, a New Delhi security researcher, said that anyone with an Aadhaar number was affected.

“This is a security lapse. You don’t have to be a consumer to access these details. You just need the Uniform Resource Locator where the Application Programming Interface is located. These can be found in less than 20 minutes,” Saini told Reuters.

In recent months, researchers and journalists who have identified loopholes in the identity project have said they were slapped with criminal cases or harassed by government agencies because of their work.

Aadhaar, a biometric identification card with over 1.1 billion users, is the world’s biggest database. But it has been facing increased scrutiny over privacy concerns following several instances of breaches and misuse.

Last Thursday, the CEO of UIDAI said the biometric data attached to each Aadhaar was safe from hacking because the storage facility was not connected to the internet.

“Each Aadhaar biometric is encrypted by a 2,048-key combination and to decode it, the best and fastest computer of our era will take the age of the universe just to hack into one card’s biometric details,” Ajay Bhushan Pandey said.

Britain’s information regulator said Saturday that it was assessing evidence gathered from a raid on the office of data mining firm Cambridge Analytica, part of an investigation into alleged misuse of personal information by political campaigns and social media companies like Facebook.

More than a dozen investigators from the Information Commissioner’s Office entered the company’s central London office late Friday, shortly after a High Court judge granted a warrant. The investigators were seen leaving the premises early Saturday after spending about seven hours searching the office.

The regulator said it would “consider the evidence before deciding the next steps and coming to any conclusions.”

“This is one part of a larger investigation by the ICO into the use of personal data and analytics by political campaigns, parties, social media companies and other commercial actors,” it said.

Authorities in Britain as well as the U.S. are investigating Cambridge Analytica over allegations the firm improperly obtained data from 50 million Facebook users and used it to manipulate elections, including the 2016 White House race and the 2016 Brexit vote in Britain.

Both Cambridge Analytica and Facebook deny wrongdoing. 

​Chief executive suspended

The data firm suspended its CEO, Alexander Nix, this week after Britain’s Channel 4 News broadcast footage that appeared to show Nix suggesting tactics like entrapment or bribery that his company could use to discredit politicians. The footage also showed Nix saying Cambridge Analytica played a major role in securing Donald Trump’s victory in the 2016 U.S. presidential election.

Cambridge Analytica’s acting chief executive, Alexander Tayler, said Friday that he was sorry that SCL Elections, an affiliate of his company, “licensed Facebook data and derivatives from a research company [Global Science Research] that had not received consent from most respondents” in 2014.

“The company believed that the data had been obtained in line with Facebook’s terms of service and data protection laws,” Tayler said.

His statement said the data were deleted in 2015 at Facebook’s request, and he denied that any of the Facebook data that Cambridge Analytica obtained were used in the work it did on the 2016 U.S. election.

Now that Facebook CEO Mark Zuckerberg has spoken publicly about the firm’s data controversy, the chief question remains whether the changes he outlined will be enough to restore the public’s trust in the social media giant.

In a series of media interviews this week, Zuckerberg went into full damage control mode about how the company handled user data when it discovered in 2015 that 50 million users’ data had been shared with Cambridge Analytica, a consultancy that advises political campaigns, thus breaking the company’s rules.

He apologized. He called the recent controversy “a major breach of trust.”

What now?

Congressional leaders have already called on Zuckerberg to testify in Congress — something that Zuckerberg appeared willing to do, according to the interviews, if he was “the right person.”

Some Facebook critics argue the firm, which relies on advertising revenue, isn’t able or willing to curtail practices that may improve users’ privacy but potentially hurt its bottom line. The company needs some sort of regulatory oversight, they say, or new laws about users’ personal data.​

But for now, Zuckerberg outlined a series of measures that would limit the amount of data collected on users, something that many privacy advocates have argued for. The firm’s revenue model, he said, is here to stay.

“I don’t think the ad model is going to go away because I think fundamentally, it’s important to have a service like this that everyone in the world can use, and the only way to do that is to have it be very cheap or free,” Zuckerberg told the New York Times.

Going back to 2014

Facebook plans to turn the clock back to 2014, before it changed its rules stopping a developers’ ability to tap into users’ friends’ data.

With the help of forensic auditors, the company plans to investigate all “large apps” — “thousands,” by Zuckerberg’s estimate, that scooped up data then.

This includes users whose data was gathered by a researcher and given to Cambridge Analytica. Facebook plans to inform affected users. Cambridge Analytica has denied that it improperly used user data.

If a developer doesn’t want to comply with Facebook’s audit, Facebook will ban it from the social network, Zuckerberg said.

“Even if you solve the problem going forward, there’s still this issue of: Are there other Cambridge Analyticas out there,” Zuckerberg told the Times. “We also need to make sure we get that under control.”

Remove access to data

In addition, the company plans to remove a developer’s access to a person’s data if someone hasn’t used the developer’s app in three months. And the company plans to reduce the amount of information collected when users sign in.

Finally, the company says it plans to make it easier to see who has access to their data and to revoke permissions. The moves are intended to curtail what critics have long complained about Facebook’s role in enabling the ongoing collection of more data on users than is needed.

Feeling ‘uncomfortable’

Zuckerberg told Recode that Facebook, with more than two billion users, has become so big and important in the lives of many around the world that he doesn’t always feel comfortable making blanket decisions.

“I feel fundamentally uncomfortable sitting here in California at an office, making content policy decisions for people around the world,” he said. “Things like where is the line on hate speech?”

He has to make the decisions he said, because he runs Facebook.

“But I’d rather not.”

Being black and working in the tech industry can be an isolating experience.

New York nonprofit Ascend Leadership analyzed the hiring data of hundreds of San Francisco Bay-area tech companies from 2007 and 2015 and issued a report last year, detailing the lack of diversity in tech.

Based on data from the U.S. Equal Employment Opportunity Commission (EEOC), Ascend found that the black tech professional workforce declined from 2.5 percent in 2007 to 1.9 percent in 2015. The outlook was even bleaker at the top. Despite 43 percent growth in the number of black executives from 2007 to 2015, blacks accounted for 1.1 percent of the total number of tech executives in 2015.

“You’re one in a sea full of people that just don’t look like you,” said Ari Melenciano, a graduate student in the Interactive Telecommunications Program at New York University. Melenciano decided to do something about it and created Afrotectopia.

Recently held at NYU, the inaugural 2-day festival brought together black technologists, designers and artists to discuss their work and the challenges of navigating the mostly white world of technology and new media.

“It’s really important for us to be able to see ourselves and build this community of people that actually look like us and are doing amazing things,” Melenciano said.

Glenn Cantave, founder and CEO of performance art coalition Movers and Shakers NYC, was on hand to demonstrate the group’s use of augmented reality and virtual reality, with apps that address racism and discrimination.

“My parents told me from a very young age that ‘You will not be treated like your white friends. There are certain privileges that you do not have,'” said Cantave. “It’s affected my conduct, it affects how I navigate spaces. I stay hyper-aware of my surroundings at all times, in terms of safety.”

Cantave and his team are working on an augmented reality book for children entitled, White Supremacy 101: Columbus the Hero? The book will contain various images that become animated when viewed with an augmented reality app. Each excerpt is intended to be a counterpoint to traditional history lessons which tell American history from a white perspective.

“If these false narratives are perpetuated for generations in the future, you’re going to have a collective consciousness that doesn’t see black people as human beings,” Cantave said. “You see it with mass incarceration, you see it with police brutality, you see it with unsympathetic immigration policy.”

But technology offers an opportunity to change that, according to Idris Brewster, creator of the app and CTO of Movers and Shakers NYC.  

“Augmented reality and virtual reality … really provides us with a unique opportunity to use very immersive technology and tell a story in a very different and engaging way,” Brewster said.

Public response has been positive. “It’s blown the kids’ minds just to see animations. A lot of kids will be like, ‘Wow, this is like Harry Potter,'” he said.

Brewster also works as a computer science instructor at Google, where in 2016, blacks made up 1 percent of the company’s U.S. tech workers. He wants to see more minorities become tech creators, not just end users.

“There’s algorithms being created in our world right now that are detrimental to people of color because they’re not made for people of color,” Brewster said. “We need to start being able to figure out how we can get our minds and our perspectives in those conversations, creating those algorithms.”

Virtual reality filmmaker Jazzy Harvey attended Afrotectopia to present her virtual-reality film, Built Not Bought, which profiles the custom-car enthusiasts of south central Los Angeles.

Harvey said she felt greater creative freedom working with the new medium. “There’s no rules, and the fact that I have no rules and no restrictions … I get to choose which story is worth telling,” Harvey said.

Afrotectopia panelists and attendees tackled a variety of topics including digital activism, entrepreneurship and education, but ultimately, it was about getting everyone in the same room together.

“To come into a space where you don’t have to assimilate culturally, you can just be yourself and talk the way that you actually talk and really have people that can connect with you culturally is so important,” Melenciano said. “Especially when you’re talking about things that you’re passionate about like tech, it’s a space where we’re so often dismissed from.”

A public apology by Facebook chief Mark Zuckerberg failed Thursday to quell outrage over the hijacking of personal data from millions of people, as critics demanded that the social media giant go much further to protect user privacy.

Speaking out for the first time about the harvesting of Facebook user data by a British firm linked to Donald Trump’s 2016 campaign, Zuckerberg admitted Wednesday to betraying the trust of its 2 billion users and promised to “step up.”

Vowing to stop data leaking to outside developers and to give users more control over their information, Zuckerberg also said he was ready to testify before US lawmakers — which a powerful congressional committee promptly asked him to do.

With pressure ratcheting up on the 33-year-old CEO over a scandal that has wiped $60 billion off Facebook’s value, the initial response suggested his promise of self-regulation had failed to convince critics he was serious about change.

“Frankly I don’t think those changes go far enough,” Matt Hancock, Britain’s culture and digital minister, told the BBC.

“It shouldn’t be for a company to decide what is the appropriate balance between privacy and innovation and use of data,” he said. “The big tech companies need to abide by the law, and we are strengthening the law.”

In Brussels, European leaders were sending the same message as they prepared to push for tougher safeguards on personal data online, while Israel became the latest country to launch an investigation into Facebook.

The data scandal erupted at the weekend when a whistle-blower revealed that British consultant Cambridge Analytica had created psychological profiles on 50 million Facebook users via a personality prediction app, developed by a researcher named Aleksandr Kogan.

The app, downloaded by 270,000 people, scooped up their friends’ data without consent — as was possible under Facebook’s rules at the time.

‘Breach of trust’

Facebook said it discovered last week that Cambridge Analytica might not have deleted the data as it certified, although the British firm denied wrongdoing.

“This was a major breach of trust and I’m really sorry that this happened,” Zuckerberg said in an interview with CNN, after publishing a blog post outlining his response to the scandal.

“Our responsibility now is to make sure this doesn’t happen again.”

With Facebook already under fire for allowing fake news to proliferate during the U.S. election, Zuckerberg also said “we need to make sure that we up our game” ahead of midterm congressional elections in November, in which American officials have warned Russia can be expected to meddle as it did two years ago.

Cambridge Analytica has maintained it did not use Facebook data in the Trump campaign, but its now-suspended CEO boasted in secret recordings that his company was deeply involved in the race.

WATCH: Facebook Under Fire for Data Misuse

And U.S. special counsel Robert Mueller, who is investigating Russian interference in the 2016 presidential race, is reportedly looking into the consultant’s role in the Trump effort.

‘Abused and misused’

Zuckerberg’s apology followed a dayslong stream of damaging accusations against the world’s biggest social network, which now faces probes on both sides of the Atlantic.

In Washington on Thursday, leaders of the House Energy and Commerce Committee urged Zuckerberg to testify without delay, saying a briefing a day earlier by Facebook officials had left “many questions” unanswered.

“We believe, as CEO of Facebook, he is the right witness to provide answers to the American people,” said a statement from the panel, calling for a hearing “in the near future.”

America’s Federal Trade Commission is reportedly investigating Facebook over the scandal, while Britain’s information commissioner is seeking to determine whether it did enough to secure its data.

On Thursday, Israel’s privacy protection agency said it had informed Facebook of a probe into the Cambridge Analytica revelations, and was looking into “the possibility of other infringements of the privacy law regarding Israelis.”

Meanwhile, European Union leaders were due to press digital giants “to guarantee transparent practices and full protection of citizens’ privacy and personal data,” according to a draft summit statement obtained by AFP.

A movement to quit the social network has already gathered momentum — with the co-founder of the WhatsApp messaging service among those vowing to #deletefacebook — while a handful of lawsuits risk turning into class actions in a costly distraction for the company.

World Wide Web inventor Tim Berners-Lee described it as a “serious moment for the web’s future.”

“I can imagine Mark Zuckerberg is devastated that his creation has been abused and misused,” tweeted the British scientist.

“I would say to him: You can fix it. It won’t be easy but if companies work with governments, activists, academics and web users, we can make sure platforms serve humanity.”
