India launches it’s own rocket in place of Soyuz-article here.


India’s most powerful rocket, the GSLV Mk.3, launched 36 OneWeb internet satellites at 2:37 p.m. EDT (1837 GMT) Saturday. The mission resumed launches for OneWeb after the suspension of flights on Russian Soyuz rockets earlier this year.

SpaceX slashes base price of smallsat rideshare program, adds “Plates”

Posted by in category: satellites

SpaceX has rolled out an upgraded version of its Rideshare program that will allow even more small satellite operators to send their spacecraft to orbit for extremely low prices.

SpaceX threw its hat into the growing ring of smallsat launch aggregators in August 2019 with its Smallsat Program. Initially, the company offered a tiered pricing scale with multiple rates for the different sizes of ports a satellite operator could attach their spacecraft to. For customers purchasing their launch services more than 12 months in advance, SpaceX aimed to charge a minimum of $2.25 million for up to 150 kilograms (~330 lb) and a flat $15,000 for each additional kilogram. Customers placing their order 6–12 months before launch would pay a 33% premium ($20,000/kg).

SpaceX may have sorely misjudged the market, however, because the company introduced a simpler, reworked pricing system just a few months later. SpaceX slashed prices threefold, removed most of the tier system, and added a portal that allowed customers to easily reserve launch services online. Compared to the first attempt, the new pricing – $1 million for up to 200 kilograms (~440 lb) and $5000 for each extra kilogram – was extraordinarily competitive and effectively solidified SpaceX as the premier source of rideshare launch services overnight. Save for an inflation-spurred increase to $1.1 million and $5500/kg, that pricing has remained stable for almost three years, and SpaceX’s Smallsat Program has become a spectacular success.

European spacecraft converge on the US for rides on SpaceX rockets

Posted by in categories: alien life, satellites

Thanks in large part to delays suffered by Arianespace’s next-generation Ariane 6 rocket, a small fleet of European satellites are simultaneously converging on the United States to hitch rides into orbit with SpaceX.

SpaceX launching European payloads is nothing new. The company has occasionally launched spacecraft built in Europe for European space agencies or companies, but the combination is exceedingly rare. For several reasons, however, what was once alien is beginning to become commonplace, and that fact is about to be made even clearer over the remainder of 2022.

SpaceX kicked off a string of six or seven launches of spacecraft built by or for Europe on October 15th. Over the weekend, the company’s workhorse Falcon 9 rocket – 70 meters (230 ft) tall, 3.7 meters (12 ft) wide, and capable of producing up to 770 tons (1.7M lbf) of thrust at liftoff – successfully launched the Hotbird 13F communications satellite into a geostationary transfer orbit (GTO) for the French satcom company Eutelsat.

Space Force will be one of the first customers of a new gas station in space

Posted by in categories: military, satellites

This week, in-space refueling company Orbit Fab won a $13.3 million USSF contract to gas up geostationary (GEO) military satellites starting in 2025. Under the four-year contract, which was first reported by Bloomberg, the Colorado-based space startup will deliver hydrazine propellant to at least one Space Force satellite in GEO.

If you build it, they will come

Jeremy Schiel, cofounder and chief development officer of Orbit Fab, says he expects the Defense Department’s buy-in to boost the company’s credibility on the commercial market.

Astronomers just spotted the most powerful flash of light ever seen

Posted by in categories: cosmology, military, satellites

Astronomers just detected what may be the most powerful flash of light ever seen.

The so-called gamma-ray burst, the most energetic type of electromagnetic explosion known to exist in the universe, was first spotted by telescopes Sunday (Oct. 9).

Gamma-ray bursts, which were discovered accidentally by U.S. military satellites in the 1960s, are likely produced when giant stars explode at the ends of their lives before collapsing into black holes, or when ultradense stellar remnants known as neutron stars collide. Within seconds, these explosions unleash as much energy as the sun will emit during its entire 10-billion-year lifetime.

How SpaceX CRS-25 Dragon provided ride for 13,000 pounds of science experiments to ISS

Posted by in categories: biotech/medical, satellites, science

SpaceX’s 25th cargo resupply mission to the International Space Station (ISS) launched from Pad 39A on July 15, 2022. The Cargo Dragon carried up to 13,000 lbs of scientific payload and tech, including 8 Cubesats. The capsule docked with the ISS on July 16, 2022.

The Dragon Capsule carried out a variety of experiments that are designed to help scientists understand more about the world around us. The scientific research performed in the microgravity aboard the ISS can’t be replicated anywhere else. Consider the ISS like an orbital laboratory, performing science for the Earth — off the Earth.

These experiments include studies of the immune system, including how it responds to stress and medications.

Quantum camera snaps objects it cannot ‘see’

Posted by in categories: military, quantum physics, satellites

Circa 2008 0.0!


A normal digital camera can take snaps of objects not directly visible to its lens, US researchers have shown. The “ghost imaging” technique could help satellites take snapshots through clouds or smoke.

Physicists have known for more than a decade that ghost imaging is possible. But, until now, experiments had only imaged the holes in stencil-like masks, which limited its potential applications.
