Chinese investments in U.S. space startups and use of Chinese software by DoD suppliers are issues of growing concern at the Pentagon, officials said.
'Planet confusion' could slow Earth-like exoplanet exploration
Thursday, 30 September 2021 15:55 Write a comment
When it comes to directly imaging Earth-like exoplanets orbiting faraway stars, seeing isn't always believing.
A new Cornell study finds that next-generation telescopes used to see exoplanets could confuse Earth-like planets with other types of planets in the same solar system.
With today's telescopes, dim distant planets are hard to see against the glare of their host stars, but next-generation tools such as the Nancy Grace Roman Space Telescope, currently under development by NASA, will be better at imaging Earth-like planets, which orbit stars at just the right distance to offer prime conditions for life.
"Once we have the capability of imaging Earth-like planets, we're actually going to have to worry about confusing them with completely different types of planets," said Dmitry Savransky, associate professor in the Sibley School of Mechanical and Aerospace Engineering (College of Engineering) and the Department of Astronomy (College of Arts and Sciences).
Head in the sky: 8-year-old Brazilian girl dubbed world's youngest astronomer
Thursday, 30 September 2021 14:11 Write a comment
When Nicole Oliveira was just learning to walk, she would throw up her arms to reach for the stars in the sky.
Today, at just eight years of age, the Brazilian girl is known as the world's youngest astronomer, looking for asteroids as part of a NASA-affiliated program, attending international seminars and meeting with her country's top space and science figures.
In Oliveira's room, filled with posters of the solar system, miniature rockets and Star Wars figures, Nicolinha, as she is affectionately known, works on her computer studying images of the sky on two large screens.
The project, called Asteroid Hunters, is meant to introduce young people to science by giving them a chance to make space discoveries of their own.
Virgin Galactic cleared to launch after US closes safety probe

Virgin Galactic said Wednesday it had been cleared for spaceflight after the Federal Aviation Agency (FAA) concluded a probe into a safety "mishap" related to its high-profile mission in July that featured company founder Richard Branson.
The FAA told the company it had accepted its proposed corrective actions related to the flight, which saw the SpaceShipTwo vehicle drop below its assigned Space Force upskilling Guardians with process mapping and automation

According to "The State of Food Security and Nutrition in the World," approximately 811 million people around the world were undernourished in 2020. Although proper nutrition is the cornerstone of good health, it is something many people still do not have access to.

DARPA, in partnership with the U.S. Air Force, completed a free flight test of its Hypersonic Air-breathing Weapon Concept (HAWC) last week. The missile, built by Raytheon Technologies, was released from an aircraft seconds before its Northrop Grumman scramjet (supersonic combustion ramjet) engine kicked on. The engine compressed incoming air mixed with its hydrocarbon fuel and began igniting th NASA launches new mission to monitor Earth's landscapes

In the Middle Bronze Age (about 3600 years ago or roughly 1650 BCE), the city of Tall el-Hammam was ascendant. Located on high ground in the southern Jordan Valley, northeast of the Dead Sea, the settlement in its time had become the largest continuously occupied Bronze Age city in the southern Levant, having hosted early civilization for a few thousand years. At that time, it was 10 times large Microgravity on demand with Earth return through ESA's Boost!

If astronauts are to set up a base and spend extended periods of time on Mars, they're going to need to be able to synthesize water and grow their own food.
Growing conditions are quite different on the Red Planet, so scientists on Earth have been conducting experiments to better understand how plants will behave in Martian regolith.

The Earth is heating up. The effects of human-caused global climate change are becoming more and more apparent as we see more record-breaking heat waves, intense droughts, shifts in rainfall patterns and a rise in average temperatures. And these environmental changes touch every part of crop production.

Researchers from Chalmers University of Technology, Sweden, have succeeded in creating tiny vehicles powered by nothing but light. By layering an optical metasurface onto a microscopic particle, and then using a light source to control it, they succeeded in moving the tiny vehicles in a variety of complex and precise ways - and even using them to transport other objects.

ESA astronaut Matthias Maurer is suited, booted and ready for his Cosmic Kiss mission. As a member of US Commercial Crew-3 he will be launched to the International Space Station in a Crew Dragon spacecraft in around one month's time for his first six-month stay in orbit.
Matthias is pictured in the SpaceX spacesuit that he will wear alongside his crew mates, NASA astronauts Kayla Barron, Thomas Marshburn and Raja Chari, during their journey to and from space.
Each SpaceX spacesuit is tailor-made for its wearer. The helmet is 3D printed and its gloves are designed to work with the touchscreens on board. The suit's primary purpose is to protect astronauts from the unlikely event of depressurisation. However, it also helps regulate an astronaut's body temperature and provides hearing and fire protection.
When an astronaut enters the Dragon capsule, they plug the suit into their seat using an umbilical. This provides the electronics to power communications, air to cool the suit and gas to pressurize the garment when needed.
This suit is only worn in the Crew Dragon capsule, not during spacewalks. Matthias is trained and certified in both the US Extravehicular Mobility Unit (EMU) and Russian Orlan spacesuits for any spacewalk he may perform in orbit.
