Emirate Mars mission: The Hope probe is a milestone for the UAE space program


“A lot of the engineering emphasis has been on making the [Mars orbital insertion] event completely autonomous,” says Pete Withnell, a scientist at the University of Colorado, Boulder, who is working with the Hope mission. “During the event, we are observers. We get to see what’s happening, but we do not get to interact in real time.”

Mission control expects to receive a signal shortly after the burn that should indicate whether Hope has fallen into a Martian “capture orbit,” although if they miss this signal, they’ll have to wait another hour or so as Hope is eclipsed by Mars and waits to emerge from around the bend. 

“This is the riskiest phase of the project,” says Omran Sharaf, project manager for the mission, adding that the propulsion system for the mission is “something you cannot really test on Earth 100%, because you cannot really simulate the environment.”

Should everything go as planned, the mission will transition from its “capture orbit” into its “science orbit” over the next few months, using that time to turn its instruments on and calibrate them for formal investigations. That transition should be completed by around the end of April or early May. According to Al Amiri, the team hopes to make the first science data available to the research community by early September. 

More than a single mission

The risks are actually the point. One of the UAE’s biggest objectives through the Emirates Mars Mission has been to spur a young generation of scientists and engineers to get into space systems development in order to help the UAE enter the space economy. Like many other countries, the UAE wants to capitalize on the rise of small-spacecraft development and “create new business ventures in space,” says Al Amiri. She says she has witnessed a swell of enthusiasm among science and engineering students, who are now taking the idea of entering the space industry seriously. 

Sharaf explains that some of the mission’s hardware was developed and manufactured by UAE companies. “It was a very good kind of test platform for us to understand the gaps that we have within our ecosystem and how we can design a program for our future missions which better integrates the private sector,” he says.

And it made sense to try for Mars rather than a high-tech demo in Earth’s orbit or even a mission to the moon. “It was a risky approach,” says Sharaf. “But as a young nation, we need to catch up. When it comes to technology and science, the learning curve is not really linear—it’s very exponential. It becomes much more difficult to catch up in the future. And this is why we’ve started to go with a Mars shot.”

When asked what a failed orbital insertion would mean for both the Hope mission and the UAE space program as a whole, Al Amiri’s answer was simple: “We will continue.” The “wild experiment,” as she calls it, has already set the ball rolling.

How a tiny media company is helping people get vaccinated

How a tiny media company is helping people get vaccinated


More than 132 million people in the US have received at least one dose of a covid-19 vaccine, and as of this week, all Americans over 16 are eligible.

But while the US has vaccinated more people than any other country in the world, vulnerable people are still falling through the cracks. Those most affected include people who don’t speak English, people who aren’t internet-savvy, and shift workers who don’t have the time or computer access to book their own slots. In many places, community leaders, volunteers, and even news outlets have stepped in to help.

One of those groups is Epicenter-NYC, a media company that was founded during the pandemic to help neighbors navigate covid-19. Based in the Queens neighborhood of Jackson Heights, which was particularly hard hit by the virus, the organization publishes a newsletter on education, business, and other local news.

But Epicenter-NYC has gone further and actually booked more than 4,600 vaccine appointments for people in New York and beyond. People who want to get vaccinated can contact the organization—either through an intake form, a hotline, a text, or an email—for help setting up an appointment.

Throughout the vaccine rollout, the group has also been documenting and sharing what it has learned about the process with a large audience of newsletter readers. 

We spoke with S. Mitra Kalita, the publisher of Epicenter-NYC, who was previously a senior vice president at CNN Digital and is also the cofounder and CEO of URL Media, a network for news outlets covering communities of color. 

This interview has been condensed and edited for clarity.

Q: How did you start setting people up with vaccine appointments? 

A: It began with two areas of outreach. First, when I had to register my own parents for a vaccine and found the process to be pretty confusing, I immediately wondered how well elderly residents, their friends and neighbors, manage this process. I just started messaging them.

The second was when a restaurant [from our small business spotlight program] reached out and said, “Do you guys know how to get vaccines for our restaurant workers?” Because I had been navigating some of this for the elderly, I started to help the restaurant workers. There started to be a similar network effect. One of the workers at this restaurant has a boyfriend who is a taxi driver; when I helped her, she asked if I could help her boyfriend; then the boyfriend texted me with some of his friends; and it kept spreading in that way. 

Q: How is Epicenter-NYC filling gaps in vaccine distribution right now? What is your process like, and who are you helping?

“There’s a lot of matchmaking going on. We can sort through a list of about 7,500 to 8,000 people who said they need help, and then find places in proximity.”

S. Mitra Kalita

A: We’ve had between 200 and 250 people reach out to volunteer. The outreach efforts range from putting up fliers, doing translations, and calling people to literally booking the appointments. 

I don’t care if you’re a Bangladeshi taxi driver in Queens and your cousin is in New Jersey. We’re going to help both of you. A woman on the Upper East Side who’s 102 years old who is homebound and needs a visit is absolutely going to get Epicenter’s help. 

What we’re doing now is continuing the route of connecting people to each other and opportunities. There’s a lot of matchmaking going on. We can sort through a list of about 7,500 to 8,000 people who said they need help, and then find places in proximity. We’ve become this wonderful marriage—a centralized operation that also embraces decentralized solutions.

Q: We know that vaccination rates lag in many communities that were hit the hardest. Why is that? What issues and barriers are people experiencing? 

A: Just before the latest Johnson & Johnson pause announcement, I said, “We’re at a point where everybody remaining is a special case.”

I think we’ve leapfrogged to vaccine hesitancy without solving for vaccine access. We don’t see a lot of hesitancy, but we do see a lot of concerns over some issues. Number one would be scheduling. We’re dealing with populations that are working two, maybe three jobs, and when they say “I have this window on Sunday at 3 p.m. until maybe 6 p.m., when my next shift starts,” they really mean that’s the only window.

Q: People have been asked to prove who they are, where they work, and where they live in order to qualify for a vaccine. This was especially true when eligibility was more limited. How did you help people face barriers around getting the documents they needed? 

A: New York State has been explicit in saying you can still get a vaccine even if you are undocumented. But that messaging doesn’t really match the on-the-ground reality.

Police in Ogden, Utah and small cities around the US are using these surveillance technologies

Police in Ogden, Utah and small cities around the US are using these surveillance technologies


One afternoon, I accompanied Heather West, the detective who’d been perusing gray pickups in the license-plate database, and Josh Terry, the analyst who’d spotted the kidnapper with the Cowboys jacket, to fly a drone over a park abutting a city-owned golf course on the edge of town. West was at the controls; Terry followed the drone’s path in the sky and maintained “situational awareness” for the crew; another detective focused on the iPad showing what the drone was seeing, as opposed to where and how it was flying. 

Of all the gadgets under the hood at the real time crime center, drones may well be the most tightly regulated, subject to safety (but not privacy) regulations and review by the Federal Aviation Administration. In Ogden, neighbor to a large Air Force base, these rules are compounded by flight restrictions covering most of the city. The police department had to obtain waivers to get its drones off the ground; it took two years to develop policies and get the necessary approvals to start making flights.

The police department purchased its drones with a mind to managing large public events or complex incidents like hostage situations. But, as Dave Weloth soon found, “the more we use our drones, the more use cases we find.” At the real time crime center, Terry, who has a master’s in geographic information technology, had given me a tour of the city with images gathered on recent drone flights, clicking through to cloud-shaped splotches, assembled from the drone’s composite photographs, that dotted the map of Ogden. 

Above 21st Street and Washington, he zoomed in on the site of a fatal crash caused by a motorcycle running a red light. A bloody sheet covered the driver’s body, legs splayed on the pavement, surrounded by a ring of fire trucks. Within minutes, the drone’s cameras had scanned the scene and created a 3D model accurate to a centimeter, replacing the complex choreography of place markers and fixed cameras on the ground that sometimes leave major intersections closed for hours after a deadly collision.

No one seemed to give much thought to the fact that quietly, people who were homeless had become the sight most frequently captured by the police department’s drone program.

When the region was hit by a powerful windstorm last September, Terry flew a drone over massive piles of downed trees and brush collected by the city. When county officials saw the resulting volumetric analysis—12,938 cubic yards—that would be submitted as part of a claim to the Federal Emergency Management Agency, they asked the police department to perform the same service for two neighboring towns. Ogden drones have also been used to pinpoint hot spots after wildland fires, locate missing persons, and fly “overwatch” for SWAT team raids.

This flight was more routine. When I pulled into the parking lot, two officers from Ogden’s community policing unit looked on as West steered the craft over a dense stand of Gambel oak and then hovered over a triangular log fort on a hillside a couple of hundred yards away. Though they’d never encountered people on drone sweeps through the area, trash and makeshift structures were commonplace. Once the RTCC pinpointed the location of any encampments, the community service officers would go in on foot to get a closer look. “We get a lot of positive feedback from runners, hikers,” one officer explained. After one recent visit to a camp near a pond on 21st Street, he and the county social service workers who accompanied him found housing for two people they’d met there. When clearing camps, police also “try and connect [people] with services they need,” Weloth said. The department recently hired a full-time homeless outreach coordinator to help. “We can’t police ourselves out of this problem,” he said, comparing the department’s efforts to keep new camps from springing up to “pushing water uphill.”

NASA has flown its Ingenuity drone helicopter on Mars for the first time

NASA has flown its Ingenuity drone helicopter on Mars for the first time


The news: NASA has flown an aircraft on another planet for the first time. On Monday, April 19, Ingenuity, a 1.8-kilogram drone helicopter, took off from the surface of Mars, flew up about three meters, then swiveled and hovered for 40 seconds. The historic moment was livestreamed on YouTube, and Ingenuity captured the photo above with one of its two cameras. “We can now say that human beings have flown a rotorcraft on another planet,” said MiMi Aung, the Ingenuity Mars Helicopter project manager at NASA’s Jet Propulsion Laboratory, at a press conference. “We, together, flew at Mars, and we, together, now have our Wright brothers moment,” she added, referring to the first powered airplane flight on Earth in 1903.

In fact, Ingenuity carries a tribute to that famous flight: a postage-stamp-size piece of material from the Wright brothers’ plane tucked beneath its solar panel. (The Apollo crew also took a splinter of wood from the Wright Flyer, as it was named, to the moon in 1969.)

The details: The flight was a significant technical challenge, thanks to Mars’s bone-chilling temperatures (nights can drop down to -130 °F/-90 °C) and its incredibly thin atmosphere—just 1% the density of Earth’s. That meant Ingenuity had to be light, with rotor blades that were bigger and faster than would be needed to achieve liftoff on Earth (although the gravity on Mars, which is only about one-third of Earth’s, worked in its favor). The flight had originally been scheduled to take place on April 11 but was delayed by software issues. 

Why it’s significant: Beyond being a significant milestone for Mars exploration, the flight will also pave the way for engineers to think about new ways to explore other planets. Future drone helicopters could help rovers or even astronauts by scoping out locations, exploring inaccessible areas, and capturing images. Ingenuity will also help inform the design of Dragonfly, a car-size drone that NASA is planning to send to Saturn’s moon Titan in 2027. 

What’s next: In the next few weeks, Ingenuity will conduct four more flights, each lasting up to 90 seconds. Each one is designed to further push the limits of Ingenuity’s capabilities. Ingenuity is only designed to last for 30 Martian days, and is expected to stop functioning around May 4. Its final resting place will be in the Jezero Crater as NASA moves on to the main focus of its mission: getting the Perseverance rover to study Mars for evidence of life.
