Brightness of first Chinese broadband constellation satellites alarms astronomers

WASHINGTON — The first satellites of a Chinese broadband constellation are significantly brighter than those of Western systems, posing a new challenge for astronomers. In a paper posted on the arXiv preprint server Sept. 30, a group of observational astronomers reported on observations of a set of 18 Qianfan, or “Thousand Sails,” satellites launched in August. The satellites are the first of a constellation that may ultimately consist of more than 14,000 satellites. The study found that the brightness of the satellites ranges from magnitude 8 when low in the sky to magnitude 4 when nearly overhead. That makes the satellites, at those higher elevations, bright enough to be seen by the naked eye — which can see objects down to magnitude 6 in dark skies — and well above the threshol...

NASA — Launch Your Creativity with Space Crafts!

ALTThis photo contains both flight (flat in the foreground) and qualification assembly (upright in the background) versions of the Solar Array Sun Shield for NASA’s Nancy Grace Roman Space Telescope. These panels will both shade the mission’s instruments and power the observatory.Seeing double? You’re looking at our Nancy Grace Roman Space Telescope’s Solar Array Sun Shield laying flat in pieces in the foreground, and its test version connected and standing upright in the back. The Sun shield will do exactly what it sounds like –– shade the observatory –– and also collect sunlight for energy to power Roman.These solar panels are twins, just like several of Roman’s other major components. Only one set will actually fly in space as part of the Roman spacecraft…so why do we need two?Sometimes...

China unveils lunar spacesuit for crewed moon mission

HELSINKI — China’s human spaceflight agency has revealed the exterior design of the spacesuit for the country’s future crewed lunar landing missions. The China Manned Space Agency (CMSA) unveiled the extravehicular lunar suit Sept. 28 in Chongqing, southwest China. CMSA is also soliciting suggestions for a name for the suit. The suit is being developed as one element of China’s goal of landing astronauts on the moon before 2030. China is also currently working on a new human-rated launcher, the Long March 10, a deep space crew spacecraft and a crew lander for the mission. A crew rover is also being designed. As part of the reveal, a promotional video showcased both the outer appearance and the suit’s key capabilities. Astronauts Wang Yaping, China’s second woman in space, and Zha...

NASA — Tiny BurstCube’s Tremendous Travelogue

ALTOn November 14, NASA is set to launch the uncrewed Artemis I flight test to the Moon and back. Artemis I is the first integrated flight test of the Space Launch System (SLS) rocket, the Orion spacecraft, and Exploration Ground Systems at NASA’s Kennedy Space Center in Florida. These are the same systems that will bring future Artemis astronauts to the Moon.ALTStanding 322 feet (98 meters) tall, the SLS rocket comprises of a core stage, an upper stage, two solid boosters, and four RS-25 engines. The SLS rocket is the most powerful rocket in the world, able to carry 59,500 pounds (27 metric tons) of payloads to deep space — more than any other vehicle. With its unprecedented power, SLS is the only rocket that can send the Orion spacecraft, astronauts, and cargo directly to the Moon on a s...

Firefly Aerospace wins contract to launch NOAA QuickSounder

SAN FRANCISCO — Firefly Aerospace won a contract to launch Quicksounder, a prototype for the National Oceanic and Atmospheric Administration’s next-generation of environmental satellites in low-Earth orbit. The value of the award was not disclosed. NASA awarded the contract to Texas-based Firefly on behalf of NOAA through the Venture-Class Acquisition of Dedicated and Rideshare (VADR) launch services contract. Through VADR, NASA awards fixed-price contracts for satellite launches. QuickSounder is the first element of NOAA’s Near Earth Orbit Network (NEON), a new generation of polar-orbiting weather satellites. The mission is intended to gather weather data for many organizations including the National Weather Service. The Southwest Research Institute is building the QuickSou...
