Manchester scientists to launch low-orbiting satellite on SpaceX mission
Tuesday, 25 May 2021 08:04
The University of Manchester is leading a multi-million pound project to launch a satellite as part of a forthcoming SpaceX mission this coming summer.
The DISCOVERER project is a 5.7 million euro project led by The University of Manchester. It aims to revolutionise Earth observation satellites, developing technologies to enable them to operate in very low Earth orbits, under 450km altitud Astroscale UK to develop space debris removal technology innovations with OneWeb

US X-37 spacecraft could technically carry up to six warheads and, with the US planning to deploy eight of these by 2025, it looks like a serious challenge, the director-general of Russian defence technology company Almaz-Antey, Yan Novikov, said Saturday.
"The official story is that these platforms were developed for scientific purposes and, well, surveillance. But we understand that havi Who's an astronaut as private spaceflight picks up speed?
Tuesday, 25 May 2021 06:19
As more companies start selling tickets to space, a question looms: Who gets to call themselves an astronaut?
It's already a complicated issue and about to get more so as the wealthy snap up spacecraft seats and even entire flights for themselves and their entourages.
Space Force warned to avoid past mistakes as it pursues new satellite acquisitions
Monday, 24 May 2021 19:20
WASHINGTON — The U.S. Space Force has plans to acquire billions of dollars worth of new satellites over the coming years and needs to make sure it avoids the missteps that plagued previous acquisitions, said the Government Accountability Office.

Solar storms are back, threatening life as we know it on Earth
Monday, 24 May 2021 15:24
A few days ago, millions of tons of super-heated gas shot off from the surface of the sun and hurtled 90 million miles toward Earth.
The eruption, called a coronal mass ejection, wasn't particularly powerful on the space-weather scale, but when it hit the Earth's magnetic field it triggered the strongest geomagnetic storm seen for years. There wasn't much disruption this time—few people probably even knew it happened—but it served as a reminder the sun has woken from a yearslong slumber.
While invisible and harmless to anyone on the Earth's surface, the geomagnetic waves unleashed by solar storms can cripple power grids, jam radio communications, bathe airline crews in dangerous levels of radiation and knock critical satellites off kilter. The sun began a new 11-year cycle last year and as it reaches its peak in 2025 the specter of powerful space weather creating havoc for humans grows, threatening chaos in a world that has become ever more reliant on technology since the last big storms hit 17 years ago. A recent study suggested hardening the grid could lead to $27 billion worth of benefits to the U.S.
UK funds beam-hopping satellite for OneWeb-led consortium in 2022

TAMPA, Fla. — A OneWeb-led group has secured government funding to launch a beam-hopping satellite in 2022, demonstrating how a spacecraft could switch its coverage area in real-time to respond to surges in demand.
A race against time to replace aging military weather satellites

The U.S. Defense Department may finally be on track to replace its aging polar-orbiting weather satellites more than a decade after pulling the plug on an ill-fated effort to cram civil and military requirements into a single system.

Cost and schedule overruns continue to grow for NASA programs
Monday, 24 May 2021 10:27
WASHINGTON — NASA suffered increasing cost overruns on its major programs again in 2020, a problem a new report says will be exacerbated by the pandemic.
The annual report by the Government Accountability Office (GAO) on major NASA programs, published May 20, found that costs of those programs grew by more than $1 billion in 2020, the fifth year in a row overall costs increased.
NASA rocket mission studying escaping radio waves
Monday, 24 May 2021 10:17
A NASA rocket mission, launching May 26, 2021, will study radio waves that escape through the Earth's ionosphere impacting the environment surrounding GPS and geosynchronous satellites, such as those for weather monitoring and communications.
Launching from NASA's Wallops Flight Facility, a Terrier-Improved Malemute suborbital sounding rocket will carry the Vlf trans-Ionospheric Propagation Experiment Rocket, or VIPER. The mission is scheduled for 9:15 p.m., Wednesday, May 26. The launch window is 9:15 p.m. to midnight EDT and the backup days are May 27-28. The launch may be visible in the mid-Atlantic region.
VIPER is studying very low frequency radio, or VLF, waves that are produced by both natural (e.g. lightning) and artificial means. During the day these waves are trapped or absorbed by the Earth's ionosphere. At night, however, some of the waves escape through the ionosphere and accelerate electrons in the Van Allen Radiation Belt.
"At night, the lower layers of the ionosphere are much less dense, and more of the VLF can leak through, propagate along the Earth's magnetic field lines, and end up interacting with the high-energy electrons trapped in the Van Allen Radiation Belts," said Dr.
