On Monday night at 11:50pm, SpaceX launched the OneWeb 16 mission. I photographed it from 135.9 miles away in St. Petersburg, FL. The first stage of this Falcon9 landed back at Cape Canaveral. After stage separation, it did a boostback burn, which is just insane to watch in the sky. The clouds were a bit more than I hoped for, but I made it work. I set up two cameras to capture the shots. One at 50mm (first pic) and one at 18mm (second pic). The third pic is an edited crop of frames from the 50mm camera showing the detail of the boostback burn.

Countdown to Launch: OneWeb’s first satellites have successfully arrived in Kourou, French Guiana.

New Blue Origin video reveals New Glenn details while company celebrates rocket's first customer.

Jeff Bezos revealed new details on Blue Origin's New Glenn booster Tuesday (March 7) at the Satellite 2017 conference in Washington, D.C. In a new promotional video released by the company, a typical flight profile for the rocket is shown including launch, payload delivery to orbit, and first stage recovery. Liftoff will occur from Cape Canaveral's LC-36, shown with heavy modifications from both crewed and uncrewed flights. Once the second stage continues the rocket's ascent to orbit, the first stage will flip around and relight its center BE-4 engine to slow itself down as it returns through the atmosphere. After using a series of six aerodynamic strakes, or fins, to maneuver through the atmosphere, New Glenn's first stage will land on a moving recovery vessel downrange in the Atlantic ocean. Blue Origin states that the moving ship will offer better stability for landing.

New Glenn will be the second orbital-class rocket to use a floating platform for first stage recovery. Although SpaceX achieved the first sea platform landing in April 2016, the technology was originally patented by Blue Origin in 2010. The two companies had a legal dispute with the U.S. Patent Office on the technology until Blue Origin withdrew the claims in 2015. Sea-based platform recovery was originally conceived in academia in the 1990s before either company was founded. 

Bezos also announced at the conference that Paris-based Eutelsat – one of the largest telecommunication satellite operators in the world – has agreed to be the first paying customer on New Glenn, signing for a mission to Geostationary Transfer Orbit sometime around 2021 or 2022. Eutelsat often gives new launch vehicles a market by flying their payloads on the initial flights of the vehicles. The following day, March 8, Bezos tweeted that OneWeb has also booked five flights on New Glenn bringing the rocket’s manifest to six. OneWeb plans to launch an initial constellation of over 650 satellites to bring broadband internet to every point on Earth. It is as yet unclear if the company’s first or second generation satellites will fly on New Glenn.

New Glenn - named after Mercury astronaut John Glenn - was unveiled in September 2016 as the next vehicle in Blue Origin's rocket family. The company successfully flew and recovered the smaller New Shepard suborbital vehicle between 2015 and 2016 paving the way for much of New Glenn's technology. Seven BE-4 engines designed and manufactured entirely by Blue Origin will power New Glenn's first stage while a single BE-4 optimized for vacuum conditions will power the second stage. An optional third stage can propel payloads into deep space and will increase the rocket's height from 269 feet to 311 feet. The first BE-4 engine was completed last week at the company's current manufacturing facility in Kent, Washington. Blue Origin is currently constructing a massive rocket manufacturing facility on Kennedy Space Center property where New Glenn's components will be manufactured and assembled. Construction is scheduled to be completed in early 2018. P/C: Blue Origin.

No dia {hoje}, a Rússia fez uma movimentação estratégica ao introduzir novos terminais de internet via satélite, uma ação em resposta ao recente apagão da rede Starlink, que comprometeu a conectividade em várias regiões. Essa iniciativa visa não apenas restaurar o acesso à internet, mas também promover uma infraestrutura de comunicação mais robusta e autônoma, destacando a crescente dependência de tecnologias espaciais em um cenário global competitivo.(...)
