“The New Shepard reusable launch system is a vertical-takeoff, vertical-landing (VTVL), suborbital crewed rocket that is being developed by Blue Origin as a commercial system for suborbital space tourism. Blue Origin is owned and led by Amazon.com founder and businessman Jeff Bezos and aerospace engineer Rob Meyerson.

The name New Shepard makes reference to the first American astronaut in space, Alan Shepard, one of the original NASA Mercury Seven astronauts, who ascended to space on a suborbital trajectory similar to that planned for New Shepard. Prototype engine and vehicle flights began in 2006, while full-scale engine development started in the early 2010s and was complete by 2015. Uncrewed flight testing of the complete New Shepard vehicle (propulsion module and space capsule) began in 2015. Flights with test passengers were planned for 2018, with commercial passenger flights initially planned to begin in 2018 as well.

On 23 November 2015, after reaching 100.5 km (62.4 mi) altitude (outer space), the New Shepard booster successfully performed a powered vertical soft landing, the first time a booster rocket had returned from space to make a successful vertical landing. The test program continued in 2016 and 2017 with four additional test flights made with the same vehicle (NS2) in 2016 and the first test flight of the new NS3 vehicle made in 2017.”

“The stacked spacecraft will take seven years to position itself to enter Mercury orbit. During this time it will use solar-electric propulsion and nine gravity assists, flying past the Earth and Moon in April 2020, Venus in 2020 and 2021, and six Mercury flybys between 2021 and 2025.

The stacked spacecraft left Earth with an hyperbolic excess velocity of 3.475 km/s (2.159 mi/s). Initially the craft is placed in an orbit similar to that of the Earth. After both the spacecraft and the Earth completed one and a half orbits, it returns to Earth to perform a gravity-assist manoeuvre and is deflected towards Venus. Two consecutive Venus flybys reduce the perihelion nearly to Mercury distance with almost no need for thrust. A sequence of six Mercury flybys will lower the relative velocity to 1.76 km/s (1.09 mi/s). After the fourth Mercury flyby the craft will be in an orbit similar to that of Mercury and will remain in the general vicinity of Mercury. Four final thrust arcs reduce the relative velocity to the point where Mercury will “weakly” capture the spacecraft on 5 December 2025 into polar orbit. Only a small manoeuvre is needed to bring the craft into an orbit around Mercury with an apocentre of 178,000 km. The orbiters then separate and will adjust their orbits using chemical thrusters.”

ULA dixit:

“United Launch Alliance will use an Atlas V 551 rocket to launch the fourth communications satellite in the Advanced Extremely High Frequency (AEHF) series for the U.S. Air Force. The launch is scheduled for 10/17. The window opens at 12:15 a.m. EDT.

AEHF satellites provide highly-secure, jam-proof connectivity between U.S. national leadership and deployed military forces. Atlas V rockets successfully launched the first three AEHF satellites in 2010, 2012 and 2013 as the new constellation was formed in geosynchronous orbit 22,300 miles above Earth.

This will be 131st mission for United Launch Alliance and our 50th launch for the Air Force. It is the 79th for an Atlas V rocket and the 9th in the 551 configuration.”

“NASA astronaut Nick Hague and Russian cosmonaut Alexey Ovchinin are in good condition following an aborted launch of their Soyuz spacecraft.

The Soyuz MS-10 spacecraft launched from the Baikonur Cosmodrome in Kazakhstan to the International Space Station at 4:40 a.m. EDT Thursday, October 11 (2:40 p.m. in Baikonur) carrying American astronaut Nick Hague and Russian cosmonaut Alexey Ovchinin. Shortly after launch, there was an anomaly with the booster and the launch ascent was aborted, resulting in a ballistic landing of the spacecraft. Search and rescue teams were deployed to the landing site. Hague and Ovchinin are out of the capsule and are reported to be in good condition.”

Blue Origin dixit:

“The BE-4 is our fourth-generation liquid rocket engine, made to take us into orbit and beyond.

The BE-4 uses oxygen-rich staged combustion of liquid oxygen and liquefied natural gas to produce 550,000 lbs. of thrust. Liquefied natural gas is commercially available, affordable, and highly efficient for spaceflight. Unlike other rocket fuels, such as kerosene, liquefied natural gas can be used to pressurize a rocket’s propellant tanks. This is called autogenous pressurization and eliminates the need for costly and complex pressurization systems, like helium. Liquefied natural gas also leaves no soot byproducts as kerosene does, simplifying engine reuse.

United Launch Alliance has selected Blue Origin’s BE-4 as the engine that will power the Vulcan rocket’s first stage. The announcement ends the need for the Russian made RD-180 on their next-generation vehicle Vulcan with the American-made BE-4.”

From the ULA press release: “Following completion of a competitive procurement, ULA has selected Blue Origin’s BE-4 engine for Vulcan Centaur’s booster stage. The liquefied natural gas (LNG) fueled booster will be powered by a pair of BE-4 engines, each producing 550,000 pounds of sea level thrust. As previously announced, ULA has selected Aerojet Rocketdyne’s RL10 engine for the Centaur upper stage, Northrop Grumman solid rocket boosters, L‑3 Avionics Systems avionics, and RUAG’s payload fairings and composite structures for the new Vulcan Centaur rocket system.”

“The 700 tonne steel table that will support Ariane 6 at liftoff was transferred to the pad at Europe’s Spaceport in French Guiana on 10 September 2018. It is so large that it arrived in parts by ship in February and was then welded together and fitted with equipment at a preparation area 250 m from the launch pad.

Moving this giant 4 m high, 20 m long and 18 m wide table to its permanent position on the centre of the pad is complex. Four hydraulic jacks lifted the table then two trollies moved the table to the edge of the launch pad. A temporary railway and a mechanical guidance system helped roll the table into position over the centre of the pad where it will be lowered with millimeter precision into its final position. Further mechanical, fluidic and electrical equipment will be installed inside and outside the table.”
