TAMPA, Fla. — Amazon is investing $19.5 million to expand its satellite processing facility at NASA’s Kennedy Space Center, Florida, to mitigate delays in deploying its 3,200-strong Project Kuiper broadband constellation. The company said Aug. 22 the investment will support a secondary, 3,900-square-meter support facility at the site, which would help accelerate launch cadence amid

Covid-19 is a risk all year round Rosem Morton for The Washington Post via Getty Images Traditionally, summer is the season of sunburn and allergies, while winter is a time for sniffles and flu, but now it seems one pathogen is upending our yearly cycle of medical maladies: the coronavirus behind covid-19. This infection also

WASHINGTON — Axiom Space is working with Nokia to adapt terrestrial wireless technologies to provide high-speed communications for the Artemis spacesuits Axiom is developing. The two companies announced a partnership Aug. 21 to develop 4G/LTE communications technologies, called the Lunar Surface Communications System (LSCS), for the suits Axiom is developing for NASA for use starting

Lasers can have a cooling effect in quantum experiments Mike_shots/Shutterstock In the strange world of quantum mechanics, nothing isn’t ever actually nothing — and now we have found that nothing, or the absence of a photon, can be used to cool things down. One of the most common ways scientists cool things down is by

WASHINGTON — As the sun’s activity ramps up, a new company is emerging to help satellite operators prepare for the potential hazards of space weather.  Ensemble Space Labs, spun off from a government contracting firm, is developing advanced forecasting tools to predict solar storms and their impacts on Earth, said CEO Ben McCrossan. Space weather,

Quantum effects result in particles behaving like waves that interfere with each other Shutterstock/sakkmesterk​e The fuzziness of the quantum world has been demonstrated on its largest-ever scale, probing the limits of quantum mechanics. More than a billion atoms inside a glass bead acted as a single quantum wave, a crucial step in making macroscopic matter

Lightning can produce special waves of energy RooM the Agency/Alamy An overlooked mechanism lets energy from lightning reach the highest layers of the atmosphere, where it could threaten the safety of satellites and astronauts. When lightning occurs, the energy it carries sometimes gives rise to special electromagnetic waves called whistlers, so named because they can
