FCC Chairman Ajit Pai talks orbital debris rules, megaconstellations, C-band auction, Ligado and more with SpaceNews. WASHINGTON — The U.S. Federal Communications Commission’s recent run of space-related regulatory actions has earned the agency both praise and scorn from the space industry. Streamlined licensing procedures adopted earlier this year promise to make it cheaper for smallsat

AN FRANCISCO – The Aerospace Corp. is working to license commercially a laser communications subsystem that downlinked data at a rate of 200 megabits per second from three-unit cubesats. The Aerospace Corp. demonstrated the latest version of its laser communications subsystem on the Rogue Alpha and Beta cubesats built for the U.S. Space Force Space

SAN FRANCISCO – An international consortium plans to launch a hyperspectral camera built by South Africa’s Dragonfly Aerospace on a NanoAvionics rideshare mission scheduled to launch on a SpaceX Falcon 9 rocket in 2021. The mission, called HyperActive, is designed to demonstrate the performance of Dragonfly’s miniature hyperspectral imager plus a high-gain X-band antenna and

This article is the first in a series of essays written by Black physicists and co-published with Physics Today as part of #BlackInPhysics week, an event dedicated to celebrating Black physicists and their contributions to the scientific community, and to revealing a more complete picture of what a physicist looks like.

WASHINGTON — Intelsat rejected a $1.8 billion claim filed by SES regarding the breakup of the C-Band Alliance, arguing instead that SES’s action cost Intelsat more than $1.6 billion in potential C-band clearing payments. SES filed the claim in July in U.S. Bankruptcy Court for the Eastern District of Virginia, where Intelsat filed for Chapter

Tranche 1 is envisioned to have about 100 to 150 space vehicles, developed and manufactured by multiple vendors. WASHINGTON — The Space Development Agency in recent months acquired 28 satellites that it plans to launch in 2022. It is now preparing for its next big procurement of up to 150 satellites to be launched in

HELSINKI — Two young Chinese rocket have secured deals with local governments for the establishment of major launch vehicle research and production facilities.  The agreements made in September demonstrate ongoing and deepening support of commercial space endeavors by Chinese provincial and local governments. Beijing-based Galactic Energy will construct a base in Jianyang, a county-level city

WASHINGTON — SpaceX launched another set of Starlink satellites Oct. 24, marking the 100th time the company has placed payloads into orbit. The Falcon 9 rocket lifted off from Space Launch Complex 40 at Cape Canaveral Air Force Station at 11:31 a.m. Eastern. The rocket’s upper stage deployed the payload of 60 Starlink satellites into

WASHINGTON — NASA’s OSIRIS-REx spacecraft collected so much material from the surface of the asteroid Bennu that the lid of its sampling head is jammed open, causing material to leak out and changing the agency’s plans for the mission. At a media briefing called by NASA on short notice Oct. 23, three days after the

WASHINGTON — Axiom Space hopes to soon finalize its first commercial mission to the International Space Station, scheduled for late 2021, as it continues development of a commercial module for the station. During a panel discussion at the International Astronautical Congress (IAC) Oct. 13, Michael Suffredini, president and chief executive of Axiom Space, said his

The recent streak of launch scrubs proves that systems are working like they should, said Col. Douglas Pentecost. WASHINGTON — A streak of United Launch Alliance and SpaceX launch scrubs has frustrated rocket company executives and space aficionados. But Space Force launch managers are not discouraged, and in fact see scrubs as proof that systems

WASHINGTON — Small launch vehicle developer ABL Space Systems announced Oct. 22 that it has started a series of static-fire tests of the upper stage of its vehicle, putting the company on track for a first launch in 2021. The company said it performed integrated stage testing of the upper stage of its RS1 vehicle

Finding a material that is a superconductor at room temperature has been the Holy Grail of condensed matter physics for over a century. In this episode we meet Ranga Dias of the University of Rochester whose team has created a material that is a superconductor at 15 °C. The only catch is that it has to

SAN FRANCISCO — Airbus Ventures invested 2.5 million Singapore dollars ($1.85 million) in Zero-Error Systems (ZES), a Singapore startup developing radiation-hardened integrated circuits. With the funding, ZES will “scale its operations, and work with international customers to deploy its products into space, as well as explore new applications, including self-driving vehicles with high levels of
