“Europe’s Vega launch vehicle operating from Europe’s Spaceport in Kourou, French Guiana, has a flawless record. Vega serves a wide range of missions and payload configurations, responding to different market opportunities. It is the ideal launcher for most scientific and Earth observation missions, benchmarked to loft 1500 kg into a 700 km-altitude circular orbit at 90° inclination.
Based on this success a more powerful Vega, Vega-C, now in development is set to launch in mid-2019 offering greater performance at no additional cost. Vega-C shares technology with Europe’s other new launcher Ariane 6. The P120C solid fuel motor will be used as the first stage for Vega-C and two or four will be used as strap-on boosters for Ariane 6.”
“Timelapse of the Russian Progress MS-10 cargo spacecraft launched on 16 November 2018 at 18:14 GMT from Baikonur cosmodrome, Kazakhstan, taken by ESA astronaut Alexander Gerst from the International Space Station.
The spacecraft was launched atop a Soyuz rocket with 2564 kg of cargo and supplies. Flying at 28 800 km/h, 400 km high, the International Space Station requires regular supplies from Earth such as this Progress launch. Spacecraft are launched after the Space Station flies overhead so they catch up with the orbital outpost to dock, in this case two days later on 18 November 2018.
The images were taken from the European-built Cupola module with a camera set to take pictures at regular intervals. The pictures are then played quickly after each other at 8 to 16 times normal speed. The video shows around 15 minutes of the launch at normal speed. The Progress spacecraft delivered food, fuel and supplies, including about 750 kg of propellant, 75 kg of oxygen and air and 440 l of water.”
“InSight is a robotic lander designed to study the interior of the planet Mars. The mission launched on 5 May 2018 and is expected to land on the surface of Mars at Elysium Planitia on 26 November 2018, where it will deploy a seismometer and burrow a heat probe. It will also perform a radio science experiment to study the internal structure of Mars.
The mission is managed by the Jet Propulsion Laboratory for NASA. The lander was manufactured by Lockheed Martin Space Systems and was originally planned for launch in March 2016. The name is a backronym for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport.
InSight’s objective is to place a stationary lander equipped with a seismometer called SEIS produced by the French space agency CNES, and measure heat transfer with a heat probe called HP3 produced by the German space agency DLR to study the planet’s early geological evolution. This could bring new understanding of the Solar System’s terrestrial planets — Mercury, Venus, Earth, Mars — and the Earth’s Moon. By reusing technology from the Mars Phoenix lander, which successfully landed on Mars in 2008, it is expected that the cost and risk will be reduced.”
“Progress MS-10, identified by NASA as Progress 71 or 71P, is a Progress spacecraft used by Roscosmos to resupply the International Space Station (ISS). Progress MS-10 launched atop a Soyuz-FG rocket on November 16, 2018, from the Baikonur Cosmodrome in Kazakhstan. Progress MS-10 docked as scheduled with the aft docking port of the Zvezda module on 18 November 2018.
The Progress MS-10 spacecraft is carrying 2564 kg of cargo and supplies to the International Space Station. The spacecraft will deliver food, fuel and supplies, including about 750 kg of propellant, 75 kg of oxygen and air, 440 kg of water.”
“Rocket Lab is a private American aerospace manufacturer and smallsat launcher with a wholly owned New Zealand subsidiary. It has developed a suborbital sounding rocket named Ä€tea and currently operates a lightweight orbital rocket known as the Electron, which provides dedicated launches for smallsats and cubesats.
The Electron test program began in May 2017, with commercial flights announced by the company to occur at a price listed in early 2018 as US$5.7 million. Launching from Mahia Peninsula, New Zealand, the rocket’s test flights took place on 25 May 2017 and 21 January 2018, while its first commercial flight took place on 11 November 2018.
Rocket Lab was founded in 2006 by New Zealander Peter Beck, the company’s CEO and CTO. Internet entrepreneur and fellow New Zealander Mark Rocket was the seed investor and co-director from 2007 to 2011. In 2009, Rocket Lab claimed it had become the first private company in the Southern Hemisphere to reach space with the Ä€tea-1 sounding rocket. The payload was not recovered. This was not deemed necessary. As an instrumentation dart, the payload was not powered; its trajectory depended only on the boost phase of flight. The boost stage was recovered, and did have flight telemetry, on which the claim of reaching space was based.
In December 2010, Rocket Lab was awarded a U.S. government contract from the Operationally Responsive Space Office (ORS) to study a low cost space launcher to place CubeSats into orbit. This agreement with NASA enables the company to use NASA resources such as personnel, facilities, and equipment for commercial launch efforts.”
“Advanced Extremely High Frequency (AEHF) is a series of communications satellites operated by the United States Air Force Space Command. They will be used to relay secure communications for the Armed Forces of the United States, the British Armed Forces, the Canadian Forces and the Royal Netherlands Armed Forces. The system will consist of six satellites in geostationary orbits, four of which have been launched. AEHF is backward compatible with, and will replace, the older Milstar system and will operate at 44 GHz Uplink (EHF band) and 20 GHz Downlink (SHF band). AEHF systems is a joint service communications system that will provide survivable, global, secure, protected, and jam-resistant communications for high-priority military ground, sea and air assets. It is the follow-on to the Milstar system. AEHF systems’ uplinks and crosslinks will operate in the extremely high frequency (EHF) range and downlinks in the super high frequency (SHF) range.
AEHF satellites use a large number of narrow spot beams directed towards the Earth to relay communications to and from users. Crosslinks between the satellites allow them to relay communications directly rather than via a ground station. The satellites are designed to provide jam-resistant communications with a low probability of interception. They incorporate frequency-hopping radio technology, as well as phased array antennas that can adapt their radiation patterns in order to block out potential sources of jamming.
AEHF incorporates the existing Milstar low data-rate and medium data-rate signals, providing 75–2400 bit/s and 4.8 kbit/sec–1.544 Mbit/s respectively. It also incorporates a new signal, allowing data rates of up to 8.192 Mbit/s. When complete, the space segment of the AEHF system will consist of six satellites, which will provide coverage of the surface of the Earth between latitudes of 65 degrees north and 65 degrees south. For northern polar regions, the Enhanced Polar System acts as an adjunct to AEHF to provide EHF coverage.”
