Intelsat filed for Chapter 11 bankruptcy protection May 13 in hopes that restructuring will position the No. 2 satellite operator to win nearly $5 billion from an FCC spectrum program. The company flies roughly 50 satellites and generates around $2 billion in annual revenue, but has labored for years under a crushing $15 billion debt load. Questions
Light show: Celebrating 60 years of the laser. (Courtesy: iStock/Terraxplorer) In October 1959, Theodore “Ted” Maiman, a relatively unknown 32-year-old physicist, set out to make what was then known as “optical maser” out of a crystal of pink ruby. The project didn’t have the most auspicious of starts. Maiman’s employers at Hughes Research Laboratory were
Antoine Riaud might need to take his wife on a second honeymoon. You’re supposed to spend that first romantic getaway obsessing over your new spouse, not how cells behave in an acoustics experiment. But when inspiration calls…well, it can be hard to ignore. For some time Riaud had been working on an idea for a
One way to help the industry is for the government to communicate what problems it needs solved and commit funding for the right solutions. The COVID-19 economic slowdown will have lasting implications on the new space sector. Yet the United States cannot afford another lost decade of commercial space innovation. Adversaries are building their own
The novel coronavirus outbreak has quickly become the largest pandemic in recent history, but it’s not unprecedented. The outbreak of the so-called “Spanish Flu”, an avian influenza virus, spread worldwide, infecting one-third of the population. While scientists are still learning how the coronavirus operates, we have lots of tools at our disposal to fight it.
Widely tuneable continuous-wave lasers based on OPO technology make it quicker and easier to characterize the internal energy structure of different qubit contenders Light fantastic: experiments to measure the properties of single-photon emitters frequently require a continuous-wave light source that can easily be tuned across a wide frequency range.

(Courtesy: Mikkel Brydegaard) Lidar technology has been used to monitor how mosquito activity varies throughout the day in a natural African landscape. The measurements were made by an international team led by
One of the most captivating aspects of the summer Olympics is watching the world’s best athletes push their bodies to the edge of what is humanly possible. In 2016, the world watched in awe as Jamaican sprinter Usain Bolt won his third consecutive Olympic gold in each of three distances—the 100m, 200m, and 4x100m relay.
If you’re on the receiving end of a snapping shrimp’s attack, prepare to be stunned. Also known as pistol shrimp, these little crustaceans shoot lethal rounds at predators and prey at highway speeds—a direct hit can be outright fatal or shock the recipient into submission. It’s not just the force of the attack that’s stunning
UUltrasound is a powerful tool for looking inside the body. The scans see through layers of tissue to reveal pumping hearts, developing fetuses, troublesome blood clots, and injured muscles. They are relatively low-cost, portable, and have few side effects. Patients aren’t exposed to ionizing radiation or confined in a small space. They are, however, slathered
The unit known as Detachment 3 is responsible to rescue astronauts if they have to abort the mission. WASHINGTON — As NASA and SpaceX prepare for a May 27 mission to fly astronauts to the International Space Station from the Kennedy Space Center, a unit of the U.S. Space Force will be on alert should
WASHINGTON — German space company OHB is moving ahead with plans to launch a commercial lunar lander mission in cooperation with Israel Aerospace Industries (IAI) in late 2022 as it looks for government and commercial customers. OHB and IAI announced an agreement in January 2019 to cooperate on an initiative to deliver payloads to the
SAN FRANCISCO — Capella Space announced a contract May 13 to provide airborne synthetic aperture radar (SAR) imagery and analytics services to the U.S. Navy. Capella, a San Francisco startup focused on establishing a constellation of SAR satellites, is not planning to offer airborne imagery as a product line. Instead, the airborne campaign is “a
SAN FRANCISCO – Silicon Valley space mapping startup LeoLabs unveiled a service May 13 to help commercial and government satellite operators avoid collisions with debris and other satellites in low Earth orbit. LeoLabs operates three ground-based phased array radars to track satellites and debris in low Earth orbit. Drawing on the radar data, LeoLabs created
Six SkySat satellites will be evenly split across two Starlink launches on Falcon 9. WASHINGTON — Planet announced that its next six SkySat satellites will fly to low Earth orbit on SpaceX Starlink missions scheduled later this summer. The six SkySats will be evenly split across two launches on SpaceX’s Falcon 9, Planet said May
