OneWeb launches 34 internet satellites into orbit to boost broadband megaconstellation

Posted by in categories: internet, satellites

A Soyuz rocket carrying 34 of OneWeb’s broadband satellites lifted off today (Feb. 6) from Baikonur Cosmodrome in Kazakhstan, rising off the pad at 4:42 p.m. EST (2142 GMT).

You Can Now Book Space on a SpaceX Rocket for $1 Million Online

Posted by in category: satellites

SpaceX has officially launched an online booking tool that lets you reserve space on a Falcon 9 rocket.

You won’t be getting a seat to travel to space yet, though — the tool is meant to offer smaller companies a way to send payloads into space, including small satellites, as TechCrunch reports.

Maxar says last year’s unnamed GEO order is new Intelsat satellite

Posted by in categories: electronics, satellites

WASHINGTON — Maxar Technologies says the geostationary satellite order it disclosed in November without naming the customer is a high-throughput Intelsat spacecraft that will also carry a pollution sensor for NASA.

Intelsat announced Feb. 3 that it had selected Maxar to build Intelsat-40e, a satellite that will provide high-throughput coverage of North America and Central America.

Intelsat-40e will also carry NASA’s Tropospheric Emissions: Monitoring of Pollution (TEMPO) hosted payload under a NASA contract with Maxar.

Spacecraft’s new moniker honors NASA’s retired Earth Science Division leader Michael Freilich.

Rocket startup Astra emerges from stealth, aims to launch for as little as $1M per flight

Posted by in categories: business, satellites

There’s yet another new rocket launch startup throwing its hat in the ring — Astra, an Alameda-based company that’s actually been operating in stealth mode (though relatively openly, often referred to as “Stealth Space Company”) for the past three years developing and testing its launch vehicle. Astra revealed its business model and progress to date in a new feature article with Bloomberg Businessweek, detailing how it plans to use mass production to deliver rockets quickly and cheaply for small satellite orbital delivery. Astra revealed it has raised more than $100 million from investors, including Eric Schmidt’s Innovation Endeavors, Airbus Ventures, Canann Partners and Salesforce co-founder Marc Benioff, to name a few, and it has big ambitions in terms of cost and capabilities.

Astra’s rockets are smaller than most existing launch vehicles in operation, designed to delivery up to 450 lbs of cargo to space, but with the specific mandate of doing so quickly and responsively. The company is a finalist (and the only remaining one) on DARPA’s Launch Challenge, the terms of which mandate that the winning company deploy two rockets from two different locations within a few weeks of each other. Astra is still in the running, while its erstwhile competitors have dropped out, with Virgin Orbit having voluntarily withdrawn and Vector Launch having gone out of business.

The DARPA challenge, which includes an award of $12 million for the winner, represents a growing trend in terms of defense customer needs: Fast turnaround and responsive operations for small satellite delivery. In an industry where the process of securing a launch service provider to actually flying a payload has typically taken at least six months in the best-case scenario, there’s a growing need for quicker timelines in the interest of building more redundancy and resilience into defense and reconnaissance space operations through use of networks of small satellites, versus single large geostationary satellites that are expensive to launch and more time-consuming to task.

Pentagon report: DoD needs to test how satellites would perform under attack

Posted by in categories: military, satellites

WASHINGTON — The Defense Department’s director of operational test and evaluation warns in a new report that the military today is not able to assess the durability of its satellites if they came under attack.

DoD plans to invest at least $100 billion in space systems over the next decade, “and we are not alone,” writes DOT&E director Robert Behler in his just released annual report for fiscal year 2019.

“We therefore must thoroughly understand how our systems will perform in space, particularly when facing man-made threats,” says the report. “Yet, the DoD currently has no real means to assess adequately the operational effectiveness, suitability and survivability of space-based systems in a representative environment.

SpaceX launches 60 new Starlink satellites, sticks rocket landing at sea

Posted by in category: satellites

CAPE CANAVERAL, Fla. — SpaceX successfully launched its fourth batch of Starlink satellites into orbit and nailed a rocket landing today (Jan. 29) following days of weather delays for the mission.

A sooty Falcon 9 rocket — which made its third flight with this launch — roared to life at 9:06 a.m. EST (1406 GMT), lifting off from Space Launch Complex 40 at Cape Canaveral Air Force Station here in Florida. The rocket carried 60 more Starlink satellites for SpaceX’s growing constellation, the second such launch by the company this month. The satellites all successfully deployed about an hour after liftoff.

SpaceX successfully launches its fourth batch of internet-beaming Starlink satellites

Posted by in categories: drones, internet, satellites

Update January 29th, 10:10AM ET: SpaceX successfully launched its Falcon 9 rocket on time this morning, deploying all 60 satellites into orbit. The rocket also performed another landing on the company’s drone ship in the Atlantic after launch. While SpaceX did catch one half of the rocket’s fairing, the other half just missed its boat.

Original story: A week after performing a crucial test flight for NASA, SpaceX is poised to launch yet another Falcon 9 rocket from Florida. This mission is tasked with sending up the latest batch of internet-beaming satellites for SpaceX, adding on to the roughly 180 satellites the company already has in orbit.

Two satellites could hit each other Wednesday — scientists call it ‘one of the most dangerous possible collisions’

Posted by in category: satellites

According to NASA, in order for a satellite to stay in orbit with the Earth, the pull of gravity must be balanced with the object’s speed. As such, the two satellites on course for collision are travelling at an extremely fast relative velocity of 14.7 kilometres per second.

“They’re going to be colliding at an incredibly high speed. And, at that speed, it’s going to probably cause the smaller satellite to break up completely into smaller fragments. And each of those fragments becomes a piece of space debris in its own right,” Gorman told ScienceAlert.

The NASA/NIVR IRAS satellite and the NRO/USN POPPY 5B satellite (aka GGSE 4) are predicted to make a close approach on Wednesday. POPPY 5B has 18-metre-long gravity gradient booms so a 15-to-30 metre predicted miss distance is alarming
