Watch SpaceX launch a Boeing-built satellite and attempt to recover its spacecraft fairing live

Posted by in categories: electronics, satellites

SpaceX is launching yet another rocket this evening — its 13th this year. This Falcon 9 launch is set for liftoff sometime during a window that’ll last for just over an hour, and that opens at 7:10 PM EST (4:10 PM PST) and extends to 8:38 PM EST (5:38 PM PST). The launch will use a first-stage rocket booster that previously flew in May and July of this year, and it’ll include an attempted landing of that booster, as well as a try at recovering both halves of the fairing used to protect the spacecraft’s cargo as it ascends to space.

The cargo itself is a satellite built by Boeing that hosts two payloads for different clients, including Japanese pay TV broadcast service provider SKY Perfect JSAT, and a high-speed broadband connectivity satellite developed by Kratos called Kacific1. The Falcon 9 spacecraft will be looking to deliver these to orbit around half-an-hour after liftoff.

It’s definitely going to be worth watching the secondary mission elements of this one, as SpaceX has so far succeeded only in recovering one half of a fairing used during a mission with a single barge stationed in the ocean. This will see it try to catch both pieces, using two ships named “Ms. Tree” and “Ms. Chief” that have been retrofitted with a large net assembly specifically for the purpose.

ESA satellite set for launch to measure sizes of exoplanets

Posted by in category: satellites

A compact exoplanet observatory built in Europe to help astronomers determine the sizes of distant worlds around other stars is scheduled for launch Tuesday from French Guiana aboard a Soyuz rocket.

Designed to build upon discoveries made by previous pioneering exoplanet telescopes — like NASA’s Kepler mission — the European Space Agency’s Characterizing Exoplanet Satellite, or CHEOPS, mission will orbit some 435 miles (700 kilometers) above Earth with a small but ultra-sensitive telescope looking at faraway stars.

CHEOPS will be capable of registering tiny changes in the brightness of stars as planets block their light from reaching the telescope. This way of observing exoplanets is called the transit method, and it’s been used by Kepler, NASA’s TESS observatory, and the French space agency’s CoRoT mission to discover planets around other stars.

European Space Agency To Launch Craft to Grab Space Debris

Posted by in categories: robotics/AI, satellites

The European Space Agency (ESA) is launching the first mission to remove a piece of space debris, set for 2025. The ClearSpace-1 mission will collect a piece of the Vespa (Vega Secondary Payload Adapter) second stage which was left by an ESA mission in 2013, which weighs approximately 100 grams and is the size of a small satellite.

The ESA selected a Swiss startup called ClearSpace to lead the mission. “This is the right time for such a mission,” Luc Piguet, founder and CEO of ClearSpace, said in a statement. “The space debris issue is more pressing than ever before. Today we have nearly 2000 live satellites in space and more than 3000 failed ones. And in the coming years, the number of satellites will increase by an order of magnitude, with multiple mega-constellations made up of hundreds or even thousands of satellites planned for low Earth orbit to deliver wide-coverage, low-latency telecommunications and monitoring services. The need is clear for a ‘tow truck’ to remove failed satellites from this highly trafficked region.”

The problem of space debris is becoming increasingly urgent, with more and more potentially hazardous objects in orbit around the planet, some at extremely high speeds. Debris can pose a risk to manned missions and the International Space Station as well as satellites and other unmanned missions.

Calling all radio amateurs! We’re challenging anyone with amateur radio equipment to catch the first signals from #OPS –SAT, ESA’s brand new space software lab. On 17 December, OPS-SAT will be launched into space with ESA’s #Cheops exoplanet satellite.

Once launched, the satellite will deploy its solar panels and ultra-high frequency antenna, and then start to send signals back home. Could you be the first on Earth to catch them? ESA’s mission control team in Darmstadt are asking for your help to find the fledgling #CubeSat 👉 http://www.esa.int/Enabling_Support/Operations/Calling_radio…nd_OPS-SAT

China shows off its newest satellite’s high-resolution 3D imagery

Posted by in categories: business, satellites

China launched the Gaofen-7 imaging satellite in November, and the country has just shared the first of its high-resolution, 3D shots. The satellite is sensitive enough to height that it should be able to spot a single person from 500 kilometers up.

Gaofen-7 is the latest in a planned series of 14 satellites intended to overhaul China’s orbital imaging capabilities. Companies like Planet are lofting hundreds of satellites to provide terrestrial businesses with up-to-date imagery, so it’s natural that China, among other countries, would want to have their own.

Already the Gaofen project has led to a huge reduction in reliance on foreign sources for this critical data, which as frictions in other areas of technology have shown, may not always be possible to rely on.

‘We Are Going To Get It Done’ — SpaceX Says It Is Trying To Stop Its Starlink Satellites Ruining The Night Sky

Posted by in categories: internet, satellites

SpaceX has said it is taking measures to tackle some of the concerns raised by astronomers about its Starlink constellation, as it gears up to launch more than a thousand satellites in the next 12 months.

The company’s Starlink mega constellation, which will add up to 42,000 satellites to orbit (only 2,000 active satellites in total orbit Earth today) to beam high-speed internet around the globe, has been taking shape in 2019. The company launched its first 60 satellites in May, followed by a second launch in November.

A third launch is planned in late December, and a fourth in January – with 24 in total planned by the end of 2020. The company hopes to launch 60 Starlink satellites roughly once every two weeks, adding more than 1,500 satellites to orbit by the end of next year alone.

Why you should take Trump’s Space Force seriously

Posted by in categories: business, economics, entertainment, humor, internet, military, satellites

The case for creating a United States Space Force is compelling. The United States military’s ability to wage war has become increasingly reliant on satellites. Navigation, reconnaissance, and communications are all handled by space assets. The world economy has become dependent on space satellites. The Internet consists of servers throughout the world linked by satellite constellations. Knock out those satellites and commercial companies’ ability to do business becomes seriously compromised. The space version of Pearl Harbor could reduce the United States to developing-world status in a single blow.

China and Russia, the main enemies of the United States in a potential conflict, are busily developing weapons systems to destroy America’s space infrastructure. Indeed, remote jamming may well do the job without resorting to a direct strike. The potential for jamming is a reason why Pence mentioned the development of jam-proof satellites in his speech. In all, Pence proposed an investment of $8 billion in new space systems during the next five years. The money is likely to be just a down payment for creating a new military branch that would achieve President Trump’s dream of achieving American space dominance.

The idea of a United States Space Force brings science fiction visions of American military personnel doing battle against an enemy in space. Indeed, the joke that has become common on social media is that President Trump is proposing to create nothing less than Star Fleet, the organization made famous in the Star Trek franchise of movies and TV shows.
