Słaby początek roku dla spółek Virgin

(...) Notowania rozpoczęły się od wartości 9,18 USD, jednakże w ciągu dwóch sesji (30 grudnia i 3 stycznia) nastąpił spadek do wartości około 7,3 USD. W kolejnych dniach nie było lepiej – wieczorem 5 stycznia cena za akcję wyniosła około 6,3 USD. Jest to dramatyczny spadek w ciągu zaledwie kilku dni. (...)

LauncherOne z polskim ładunkiem
  13.01. o 21:39 z pasa 12/30 w Mojave Air and Space Port wystartował samolot Boeing-747-400 "Cosmic Girl". Podwieszona pod nim rakieta LauncherOne została zrzucona o 22:51:39, a 3,25 sekundy później nastąpił zapłon silnika NewtonThree jej pierwszego stopnia. Rakieta wyniosła w T+53' 59" na orbitę o parametrach: hp=500 km, ha=500 km, i=45° siedem satelitów: dwa dla polskiej firmy SatRevolution - STORK-3 i SteamSat-2, dwa dla NASA w ramach programu ELaNa 29 - PAN A i PAN-B, ADLER-1, TechEdSat-13 i GEARRS-3, a także ładunki dla DoD w ramach programu STP-27VPB.

LauncherOne launches “Above the Clouds”

Sarah, Eric, Stanny, and Bryce—these are the people who flew on board Cosmic Girl and executed a flawless #AboveTheClouds mission. We are so proud to have them in the #VirginFamily!

ADLER-1 cubesat - flying an eagle

The ADLER-1 satellite was developed in partnership with the Austrian Space Forum (OeWF) and Findus Venture GmbH. ADLER-1 is part of a growing movement to address the issue of dangerous space debris and improve sustainability in Low Earth Orbit.

We were delighted to carry NASA's 29th Educational Launch of Nanosatellites (ELaNa) mission AND the 13th CubeSat for the TechEdSat series to orbit yesterday! #AboveTheClouds Thank you for flying with us again! Let's do this again soon, shall we?

Virgin Orbit celebrates third successful launch in a row

(...) Two Virgin Orbit launch engineers — Sarah Barnes and Bryce Schaefer — were also aboard the Cosmic Girl carrier jet to verify the LauncherOne rocket was ready for release about 210 miles (340 kilometers) west of San Diego. (...)

The satellites included four nano-spacecraft flown under a contract with the U.S. military’s Space Test Program, which designated the mission STP-27VPB.

Those payloads were Globalstar Experiment And Risk Reduction Satellite 3, or GEARRS 3, designed to test connectivity between a CubeSat and the commercial communications network operated by Globalstar. That mission is led by the Air Force Research Laboratory.

Two small satellites funded by NASA were also among the payload package booked by the military’s Space Test Program. They included TechEdSat 13, a three-unit CubeSat the size of a shoebox, from NASA’s Ames Research Center.

TechEdSat 13 hosts several experiments, including an artificial intelligence and machine learning module with a neuromorphic processor designed to execute algorithms in a way that mimics the human brain. The spacecraft also carries an “exo-brake” device that will deploy to help the satellite generate atmospheric drag, allowing TechEdSat 13 to drop out of orbit faster.

The atmospheric brake technology could be used in future small satellites to help ensure they can de-orbit after completing their missions, preventing the creation of unnecessary space junk.

The Pathfinder for Autonomous Navigation, or PAN, mission consists of two CubeSats, each the size of a loaf of bread, that will attempt to dock together in orbit. It’s the first CubeSat mission to attempt an autonomous rendezvous and docking.

The project is a partnership between NASA and Cornell University. NASA, in a statement on its website, said the PAN mission is “one of the most advanced autonomous CubeSat systems that has flown to date.”

The PAN CubeSats have a cold gas propulsion system and reaction wheel attitude control devices, according to NASA. The docking experiment is expected to occur a few months after launch, with the CubeSats using GPS navigation to position themselves with an accuracy of several centimeters.

Three commercial satellites were also on Virgin Orbit’s rocket Thursday.

One of them, named ADLER 1, is a CubeSat designed to measure the space debris environment in low Earth orbit. The spacecraft hosts a short-range radar and a deployable piezoelectric array to detect and register space debris fragments, helping scientists verify models of the distribution of space junk in orbit.

The ADLER 1 mission is a partnership between Spire, a commercial satellite company, Findus Venture, and the Austrian Space Forum.

The Polish company SatRevolution had two satellites on the mission. One, named STORK 3, will join SatRevolution’s constellation of Earth-imaging nanosatellites.

The other one is named SteamSat 2, and is a partnership between SatRevolution the British space propulsion firm SteamJet. SteamSat 2 will test a water-based thruster designed to change the altitude or inclination of small satellites.
