Suborbital space tourism finally arrives | FCC prepares to run public C-band auction | The big four in the U.S. launch industry — United Launch Alliance, SpaceX, Blue Origin and Northrop Grumman — hope to be one of two providers that will receive five-year contracts later this year to launch national security payloads starting in 2022. | China’s launch rate stays high | The International Space Station is the largest ever crewed object in space.

 
Making nuclear energy cost-competitive
Nuclear energy is a low-carbon energy source that is vital to decreasing carbon emissions. A critical factor in its continued viability as a future energy source is finding novel and innovative ways to improve operations and maintenance (O&M) costs in the next generation of advanced reactors. The U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) established the Generating Electricity Managed by Intelligent Nuclear Assets (GEMINA) program to do exactly this. Through $27 million in funding, GEMINA is accelerating...

Lincoln Laboratory decommissions Lincoln Experimental Satellite–9
The longest continuously operating communications satellite in U.S. history, Lincoln Experimental Satellite–9 (LES-9), was decommissioned by MIT Lincoln Laboratory on May 20. The LES research team has been monitoring the satellite since it was launched in 1976. The gradual reduction in available power, coupled with the loss of the primary S-band telemetry data in early 2020, led to the decision to retire the satellite. “The Lincoln Experimental Satellite program was a monumental technical achievement and created the architectural framework...

Podcast transcript: A tale of two classes...
Like this year’s seniors, the Class of 1970 had its final semester disrupted: Fifty years ago, growing unrest over the Vietnam War led to the cancellation of MIT classes. In the podcast and transcript below, Karen Arenson ’70 and senior Bahrudin Trbalic share their experiences. Karen A.: My classmates and I do feel a connection to the Class of 2020 and empathize with the way their final semester has been up-ended. Narrator: When Class of 1970 president, Karen Arenson,...

Physicists measure a short-lived radioactive molecule for...
Researchers at MIT and elsewhere have combined the power of a super collider with techniques of laser spectroscopy to precisely measure a short-lived radioactive molecule, radium monofluoride, for the first time. Precision studies of radioactive molecules open up possibilities for scientists to search for new physics beyond the Standard Model, such as phenomena that violate certain fundamental symmetries in nature, and to look for signs of dark matter. The team’s experimental technique could also be used to perform laboratory...

How often do vaccine trials hit paydirt?
Vaccines are more likely to get through clinical trials than any other type of drug — but have been given relatively little pharmaceutical industry support during the last two decades, according to a new study by MIT scholars. Over a two-decade span from January 2000 to January 2020, private-sector vaccine-development efforts succeeded in bringing a drug to market 39.6 percent of the time, the researchers found. By contrast, programs to develop anti-infective therapeutics — medicines that lessen the severity...

Hacking Commencement
In the finest MIT tradition of community-driven innovation, the Commencement Committee and a core group of engineers, technologists, and artists across campus are putting minds and hands to work to create a meaningful, engaging online Commencement experience for the Class of 2020.  Moving the tradition-rich celebration online without diminishing its significance, and with less than two months to plan, is a complex problem. The organizing team knew from the outset that the challenge would be to achieve the key...

Meet the MIT bilinguals: Dual materials science...
In high school, Talia Khan was passionate about musical theater. So, she was thrilled when she got to go to New York and see one of her idols, Audra McDonald, perform on Broadway in “Lady Day at Emerson’s Bar and Grill.” She waited at the stage door to meet her after the show, and she told McDonald how much she hoped to be a successful singer, too. As Khan recounts the conversation, McDonald said, “I won’t tell you not...

Undergraduates develop next-generation intelligence tools
The coronavirus pandemic has driven us apart physically while reminding us of the power of technology to connect. When MIT shut its doors in March, much of campus moved online, to virtual classes, labs, and chatrooms. Among those making the pivot were students engaged in independent research under MIT’s Undergraduate Research Opportunities Program (UROP).  With regular check-ins with their advisors via Slack and Zoom, many students succeeded in pushing through to the end. One even carried on his experiments...

Search-and-rescue algorithm identifies hidden “traps” in ocean...
The ocean is a messy and turbulent space, where winds and weather kick up waves in all directions. When an object or person goes missing at sea, the complex, constantly changing conditions of the ocean can confound and delay critical search-and-rescue operations. Now researchers at MIT, the Swiss Federal Institute of Technology (ETH), the Woods Hole Oceanographic Institution (WHOI), and Virginia Tech have developed a technique that they hope will help first responders quickly zero in on regions of...

A Ticketmaster for science seminars
One of the perks of an academic’s pre-pandemic life was the chance, at least once a week, to take a break from problem sets and proofs, and walk down the hall or across campus to sit in on cutting-edge research presented by invited experts from around the world. Offered through a department’s regular seminar series, these talks were also opportunities to get some friendly face-to-face with colleagues who were otherwise buried in their own work. And on occasion, a...

Informal Transit Is Crucial for Some. Can...
In Kenya’s capital Nairobi, business as usual has begun to return to the central commercial district, as pedestrians throng crowded streets where hawkers sell their wares—at least until a government mandated curfew forces everyone to rush home by 7 pm. To get around, most commuters rely on fleets of privately owned minivans and buses, called matatus, an example of the kinds of informal transportation services common in the developing world. Like businesses everywhere, they have been hard hit by...

Ten from MIT awarded 2020 Fulbright Fellowships
Ten MIT students and recent alumni are recipients of awards from the Fulbright U.S. Student Program. They will use their grants to conduct research, earn a graduate degree, or teach English abroad. This year’s Fulbright award winners are headed to Australia, Brazil, France, China, the Czech Republic, Germany, and Malaysia. Three other MIT students received Fulbright awards, but declined them to pursue other opportunities. Sponsored by the U.S. Department of State, the Fulbright U.S. Student Program offers opportunities for...

Deep learning accurately stains digital biopsy slides
Tissue biopsy slides stained using hematoxylin and eosin (H&E) dyes are a cornerstone of histopathology, especially for pathologists needing to diagnose and determine the stage of cancers. A research team led by MIT scientists at the Media Lab, in collaboration with clinicians at Stanford University School of Medicine and Harvard Medical School, now shows that digital scans of these biopsy slides can be stained computationally, using deep learning algorithms trained on data from physically dyed slides. Pathologists who examined...

Solar energy farms could offer second life...
As electric vehicles rapidly grow in popularity worldwide, there will soon be a wave of used batteries whose performance is no longer sufficient for vehicles that need reliable acceleration and range. But a new study shows that these batteries could still have a useful and profitable second life as backup storage for grid-scale solar photovoltaic installations, where they could perform for more than a decade in this less demanding role. The study, published in the journal Applied Energy, was...
