WASHINGTON — Lynk will start testing cellular connectivity services with its first small satellite in the near future as it plans to begin commercial service early next year. During a panel discussion at the SmallSat Symposium Feb. 11, Margo Deckard, co-founder and chief operating officer of Lynk, said tests it performed last year demonstrated its

After conversion of a standard clinical linac, it can deliver a FLASH beam with a dose rate 3000 times higher than used for conventional radiation treatment. (Courtesy: Brian Pogue) Researchers from Dartmouth have developed a method to convert a standard clinical linear accelerator (linac) used for radiation therapy to deliver a FLASH-capable, ultrahigh-dose rate (UHDR)

WASHINGTON — NASA needs to pursue “aggressive” development of space nuclear propulsion technologies if the agency wants to use them for human missions to Mars in the next two decades, a report by a National Academies committee concluded. A Feb. 12 study by the National Academies, sponsored by NASA, said both nuclear thermal propulsion (NTP)

By Allison Kubo Hutchison You are enjoying a sunny beach day, showing off a new swimsuit. You take a dip in the water, you feel something brush your foot. You look down and it’s a trilobite. Your first panicked thought: Do trilobites bite? Other than the fact that trilobite went extinct 252 million years ago,

“We’ve been doing space operations for years under the Air Force. But as a service we now have to advocate for new resources,” said Lt. Gen. B. Chance Saltzman. WASHINGTON — The Space Force is by far the smallest branch of the U.S. military and will have to “punch above its weight” to get its

Demonstrating optical crosslinks is a top priority for SDA and DARPA as any future military network has to be able to move huge amounts of data. WASHINGTON — The Pentagon’s space agency this year will launch a series of experiments — including satellites with laser links and missile-tracking sensors — as is prepares to begin

HawkEye 360 CEO John Serafini: Government contracts help startups raise private funds needed to pay for the space and ground infrastructure. WASHINGTON — About 270 of the 620 remote sensing satellites in orbit are privately owned with about 200 of these belong to U.S. companies, according to the Aerospace Corp. Only about 50 are owned

In this episode of the Physics World Weekly podcast we meet physicist Jennifer Rieser who has just moved from the Georgia Institute of Technology to Emory University, where she studies how snakes use tiny structures on their undersides to help propel themselves. Rieser talks about her recent research that suggests that microscopic pits on the

SAN FRANCISCO — Hewlett Packard Enterprise is preparing to send a second-generation Spaceborne Computer to the International Space Station later this month. The Spaceborne Computer-2 will be linked to Microsoft’s Azure cloud through NASA and HPE ground stations, meaning the space station will have far more data processing power and better connections with Earth than

WASHINGTON — NASA is no longer considering launching the Europa Clipper mission on the Space Launch System, deciding instead to launch the spacecraft on a commercial rocket it will procure in the next year. During a Feb. 10 presentation at a meeting of NASA’s Outer Planets Assessment Group (OPAG), leaders of the Europa Clipper project

SAN FRANCISCO – Satellite communications startup Analytical Space Inc. won a $26.4 million contract to develop and launch six cubesats and two hosted payloads to begin establishing the Fast Pixel Network for optical communications. The three-year contract was awarded by AF Ventures, the service’s venture arm, with funding from the U.S. Space Force Space and

By: Hannah Pell Being homebound during winter often means higher electricity bills for those of us north of the Sun Belt. And for many currently working remotely or attending school virtually, there may be added strain on top (although hopefully not to the same extent as the Griswold family’s infamous holiday lights). When so many

SAN FRANCISCO – Money will continue flowing into the space industry from government agencies, private equity firms and public markets, according to panelists at the 2021 SmallSat Symposium. “It has never been a better time to raise money for ventures in and around space,” said James Murray, a partner at investment bank PJT Partners. While

Exotic hint: the PandaX-II detector being assembled. (Courtesy: PandaX collaboration) New data from the PandaX-II particle detector in China leave open the possibility that the XENON1T experiment in Italy has found evidence of new physics. In June 2020 researchers working on XENON1T announced the detection of around 50 events above background levels and concluded that

On Oct. 21, 2020, the Promoting Research and Observations of Space Weather to Improve the Forecasting of Tomorrow (PROSWIFT) Act was signed into law. This act culminates a multiyear bipartisan effort championed by Sens. Gary Peters (D-Mich.) and Cory Gardner (R-Colo.), and Reps. Ed Perlmutter (D-Colo.) and Mo Brooks (R-Ala.). It directs government agencies (including
