For millennia, humans in the high latitudes have been enthralled by auroras - the northern and southern lights. Yet even after all that time, it appears the ethereal, dancing ribbons of light above Earth still hold some secrets.
In a new study, physicists led by the University of Iowa report a new feature to Earth's atmospheric light show. Examining video taken nearly two decades ago, the NASA's On-orbit Servicing, Assembly, and Manufacturing 1 Mission Ready for Spacecraft Build

NASA is one step closer to robotically refueling a satellite and demonstrating in-space assembly and manufacturing thanks to the completion of an important milestone.
In April 2021, NASA and Maxar Technologies successfully completed the On-orbit Servicing, Assembly, and Manufacturing 1 (OSAM-1) mission spacecraft accommodation Critical Design Review (CDR). This milestone demonstrates that US not planning to shoot down errant Chinese rocket: defense chief

The US military has no plans to shoot down an out -of-control Chinese rocket now hurtling towards Earth, Defense Secretary Lloyd Austin said Thursday.
"We have the capability to do a lot of things, but we don't have a plan to shoot it down as we speak," Austin told journalists.

Six metres high, weighting 1000 kilograms and assembled from over 24,000 parts: These are the dimensions of the second generation of European weather satellites, which in future will collect weather data some 800 kilometres above us.
The basic structure of the second flight model was assembled in RUAG Space's clean rooms in Zurich and is now being delivered to customers by special 31-metre Starliner test flight scheduled for July 30

WASHINGTON — NASA and Boeing have scheduled a second uncrewed test flight of the CST-100 Starliner commercial crew spacecraft for July 30.
In separate statements, the agency and the company said they were planning to launch the Starliner on a United Launch Alliance Atlas 5 at 2:53 p.m.
Northrop Grumman to supply navigation payloads for DARPA’s Blackjack satellites

WASHINGTON — The Defense Advanced Research Projects Agency awarded Northrop Grumman a $13.3 million contract to provide positioning, navigation and timing (PNT) payloads for the Blackjack program.
Blackjack is a DARPA project to demonstrate the military utility of small satellites in low Earth orbit to provide communications, missile warning and PNT.

NASA and Boeing are now targeting July 30 for an uncrewed test flight of the aerospace company's troubled Starliner capsule to the International Space Station, they announced Thursday.
The launch has been postponed multiple times, with the last announced date of April scuppered due to a cold snap that caused extensive power outages in Texas in March.
The NASA Commercial Crew program is run partly from the Johnson Space Center in Houston, though it launches from Cape Canaveral in Florida.
Lift-off is now scheduled for 2:53 pm Eastern Time (1853 GMT) on July 30.
"NASA and Boeing have done an incredible amount of work to get to this point," said Steve Stich, Commercial Crew program manager.

Space weather is difficult to predict—with only an hour to prevent disasters on Earth
Thursday, 06 May 2021 12:13 Write a comment
Recent developments at the forefront of astronomy allow us to observe that planets orbiting other stars have weather. Indeed, we have known that other planets in our own solar system have weather, in many cases more extreme than our own.
Our lives are affected by short-term atmospheric variations of weather on Earth, and we fear that longer-term climate change will also have a large impact. The recently coined term "space weather" refers to effects that arise in space but affect Earth and regions around it. More subtle than meteorological weather, space weather usually acts on technological systems, and has potential impacts that range from communication disruption to power grid failures.
Image: NASA's Lucy high gain antenna up close

Lucy's epic journey to observe Jupiter's Trojan asteroids requires a reliable communications link back to Earth, and so the spacecraft is outfitted with a 6.5-ft. (2-meter)-wide high gain antenna for this task.
Designed and built by Lockheed Martin, this same style antenna has been used to return science data from Mars and transfer back photos of asteroid Bennu. Lucy's antenna will send back the first-ever close up images and spectra of Trojan asteroids.
The signal from the antenna will also help determine the mass of these never-before-visited space objects revealed by tiny changes in frequency caused by the Doppler effect.
