Satellite operators weigh strategies to compete against growing Starlink network
Monday, 05 April 2021 23:07
WASHINGTON — As SpaceX continues to expand its Starlink communications network and promote its services, established satellite operators are figuring out strategies to remain competitive.
During the Satellite 2021 LEO Digital Forum April 6, Gwynne Shotwell, SpaceX president and chief operating officer, said the company is moving forward with plans to offer Starlink satellite internet services directly to consumers and also is eyeing the U.S.
NASA's first weather report from Jezero Crater on Mars
Monday, 05 April 2021 20:26
The weather often plays a role in our daily plans. You might put on a light jacket when the forecast calls for a cool breeze or delay your travel plans because of an impending storm. NASA engineers use weather data to inform their plans, too, which is why they're analyzing the conditions millions of miles away on Mars.
The Mars Environmental Dynamics Analyzer (MEDA) system aboard NASA's Perseverance rover first powered on for 30 minutes Feb. 19, approximately one day after the rover touched down on the Red Planet.
Early combined tests mimic Ariane 6 liftoff

Scientists create stable nanosheets containing boron and hydrogen atoms with potential applications in nanoelectronics and quantum information technology.
What's thinner than thin? One answer is two-dimensional materials - exotic materials of science with length and width but only one or two atoms in thickness. They offer the possibility of unprecedented boosts in device performance for el Scientists achieve single-photon imaging over 200km

As the Royal Australian Air Force (RAAF) celebrated 100 years with a spectacular and well-attended flyover in Canberra yesterday, many eyes were lifted to the skies. But RAAF's ambitions go even higher, as its motto "through adversity, to the stars" hints. The Chief of Air Force, Air Marshall Mel Hupfeld, announced the intention to create a new "space command".

Monday, 05 April 2021 13:45
Nine of the hottest years in human history have occurred in the last decade. Without a major shift in this climate trajectory, the future of life on Earth is in question. Should humans, whose fossil-fueled society is driving climate change, use technology to put the brakes on global warming?

As environmental and energy crises become increasingly more common occurrences around the world, a thermal energy harvester capable of converting abundant thermal energy - such as solar radiation, waste heat, combustion of biomass, or geothermal energy - into mechanical energy appears to be a promising energy strategy to mitigate many crises.

Remote-controlled Venus flytrap "robo-plants" and crops that tell farmers when they are hit by disease could become reality after scientists developed a high-tech system for communicating with vegetation.
Researchers in Singapore linked up plants to electrodes capable of monitoring the weak electrical pulses naturally emitted by the greenery.

When it comes to powering mobile robots, batteries present a problematic paradox: the more energy they contain, the more they weigh, and thus the more energy the robot needs to move. Energy harvesters, like solar panels, might work for some applications, but they don't deliver power quickly or consistently enough for sustained travel.

A single "super photon" made up of many thousands of individual light particles: About ten years ago, researchers at the University of Bonn produced such an extreme aggregate state for the first time and presented a completely new light source. The state is called optical Bose-Einstein condensate and has captivated many physicists ever since, because this exotic world of light particles is home Lockheed Martin expands quick, affordable launch capability with ABL Block Buy
