Rocket Lab has shifted a pair of Electron launches of NASA storm-monitoring cubesats from Virginia to New Zealand, avoiding a potential conflict with another launch.
Juice: running on solar power in the dark
Tuesday, 11 April 2023 10:00
Welcome to Jupiter space: to one side looms the vast cloudy face of the largest planet in our Solar System; in the other appears a shrunken Sun, like a spotlight in the sky, with just 3% of the illumination from Earth orbit arriving here. This basic fact presented a major challenge to those planning ESA’s Jupiter Icy Moons Explorer, Juice, mission: how to make solar power work in such a gloomy environment, located an average 778 million km away from our parent star?
China to target asteroid 2019 VL5 for 2025 planetary defense test

NASA awards agreement for high-resolution synthetic aperture radar
Tuesday, 11 April 2023 06:39
NASA has awarded a sole source Blanket Purchase Agreement (BPA) to Capella Space Corporation of San Francisco to provide high-resolution Synthetic Aperture Radar (SAR) (0.5 meter to 1.2 meters) commercial Earth observation data products.
Under this agreement, the government will issue fixed-price BPA Calls for these products, at a not-to exceed value of $7 million per Call. The work will b Was plate tectonics occurring when life first formed on Earth?
Tuesday, 11 April 2023 06:39
Earth is a dynamic and constantly changing planet. From the formation of mountains and oceans to the eruption of volcanoes, the surface of our planet is in a constant state of flux. At the heart of these changes lies the powerful force of plate tectonics-the movements of Earth's crustal plates. This fundamental process has shaped the current topography of our pla Beneath the Earth, ancient ocean floor likely surrounds the core
Tuesday, 11 April 2023 06:39
Through global-scale seismic imaging of Earth's interior, research led by The University of Alabama revealed a layer between the core and the mantle that is likely a dense, yet thin, sunk ocean floor, according to results published in Science Advances.
Seen only in isolated patches previously, the latest data suggests this layer of ancient ocean floor may cover the core-mantle boundary. Su Guiding JUICE to Jupiter
Tuesday, 11 April 2023 02:43
This phenomenal endeavour, led by the European Space Agency, is powered by Airbus technology. Our engineers have rarely faced a greater challenge than enabling such a journey. The JUICE probe will encounter extreme temperatures, intense radiation and decreasing solar energy during its 5 billion kilometre journey. Being self-sufficient in energy generation and storage is key to the mission's succ NASA study helps explain limit-breaking ultra-luminous x-ray sources
Tuesday, 11 April 2023 02:43
These objects are more than 100 times brighter than they should be. Observations by the agency's NuSTAR X-ray telescope support a possible solution to this puzzle.
Exotic cosmic objects known as ultra-luminous X-ray sources produce about 10 million times more energy than the Sun. They're so radiant, in fact, that they appear to surpass a physical boundary called the Eddington limit, which A Jovian journey to the icy worlds of a Gas Giant
Tuesday, 11 April 2023 02:43
On April 13, 2023, the European Space Agency is scheduled to launch a rocket carrying a spacecraft destined for Jupiter. The Jupiter Icy Moons Explorer - or JUICE - will spend at least three years on Jupiter's moons after it arrives in 2031. In October 2024, NASA is also planning to launch a robotic spacecraft named Europa Clipper to the Jovian moons, highlighting an increased interest in these Orion stretches its wings ahead of first crewed Artemis mission
Tuesday, 11 April 2023 02:43
Before NASA's Orion spacecraft for the Artemis II mission can be outfitted with its solar array wings, teams at the agency's Kennedy Space Center must first verify that the arrays extend and close properly. On March 17, 2023, technicians inside the Florida spaceport's Neil Armstrong Operations and Checkout Building unfurled one of the wings to confirm all mechanisms operate as expected.
