Air Force satellite completes two-year experiment to study the medium Earth orbit environment

Posted by in category: satellites

AFRL completed a two-year space experiment that will help better understand the effects of radiation on space hardware in medium Earth orbit.


WASHINGTON — The U.S. Air Force Research Laboratory announced July 19 it has completed a two-year experiment that will help better understand the effects of radiation on space hardware in medium Earth orbit.

Known as the Demonstration and Science Experiments (DSX) mission, the spacecraft was one of 24 payloads launched June 25, 2019, on a SpaceX Falcon Heavy rideshare.

Astronomers push for global debate on giant satellite swarms

Posted by in category: satellites

Now, in what would be the biggest international step yet towards addressing these concerns, diplomats at a United Nations forum next month might discuss whether humanity has a right to ‘dark and quiet skies’. The debate could initiate a framework for how scientists and the public would deal with the flood of new satellites — with many more expected.


Working with the United Nations, scientists hope to establish standards for satellite ‘megaconstellations’ and reduce disruption of astronomical observations.

Amazon acquires Facebook’s Satellite Internet team!

Project Kuiper going strong to compete SpaceX’s StarLink, OneWeb and Telesat.


The deal bolsters Amazon’s $10 billion effort to develop low Earth orbit (LEO) satellites capable of delivering high-speed broadband internet around the globe, while marking the end of Facebook’s ultimately unsuccessful efforts to do the same.

Massive solar storm heading towards Earth can impact GPS, mobile signal. Details here

Posted by in categories: mobile phones, satellites

According to NASA, the solar storm is travelling towards Earth at a velocity of 1.6 million km/hr and the speed might even increase more.

The satellites in the Earth’s upper atmosphere are also expected to get impacted by the incoming flares. This will directly impact GPS navigation, mobile phone signal and satellite TV. The power grids can also be impacted due to the solar flares.

On the positive side, the solar flares will create an amplified view of Aurora lights in North or South Pole. The people living near the poles will get to experience these lights.

What do you do if you discover a big rock on a collision course with Earth and have very little time to take action?


Large telecommunication satellites used for TV broadcasting could be quickly and easily repurposed as anti-asteroid weapons according to European aerospace company Airbus.

SpaceX founder Elon Musk recently shared that the company is already providing Starlink Beta broadband internet service to over 69420 users globally out of over half-a-million customers who pre-ordered the internet service via Starlink.com. According to SpaceX President Gwynne Shotwell, the Starlink constellation is currently actively beaming its signal to users in 11 countries (now 12), including portions of the United States, Canada, United Kingdom, Germany, Belgium, France, Austria, Netherlands, Australia, and New Zealand. More European countries and regions in the United States will have coverage during the second half of 2021 and early 2022.

This week, SpaceX e-mailed potential customers in the European country of Denmark –“Starlink is now available in limited supply in Denmark!” the e-mail reads. “Users can expect to see data speeds vary from 50Mb/s to 150Mb/s [megabits per second] over the next several months as we enhance the Starlink system. There will also be brief periods of no connectivity at all,” SpaceX wrote in the e-mail. “As we launch more satellites, install more ground stations and improve our networking software, data speed, latency and uptime will improve dramatically.” To date, SpaceX has launched approximately 1740 internet-beaming Starlink satellites out of over 12000 that will be part of the global broadband constellation.

Space Development Agency’s first satellites to launch on SpaceX mission

Posted by in categories: military, satellites

The first five payloads from the Space Development Agency, an organization charged with rapidly infusing emerging technologies into the U.S. military’s space programs, are among more than 80 satellites awaiting launch from Cape Canaveral Tuesday on a SpaceX Falcon 9 rocket.

Established in 2019, the Space Development Agency plans to deploy hundreds of small satellites to enable improved communications for the U.S. military. SDA’s strategy leans on the rapid development of new commercial space technology, including new types of sensors and cheaper, easier-to-produce small satellites that can be deployed in large constellations in low Earth orbit.

SDA plans to launch the first tranche of 28 satellites to provide initial infrared missile detection and low-latency data relay services in late 2022 and early 2023. Twenty of those satellites, part of the “transport layer,” will be developed by Lockheed Martin and York Space Systems for communications support. The other eight “tracking” satellites will be supplied by SpaceX and L3Harris for missile detection and tracking.
