International Space Station

Expedition 66 continues

On Nov 17 Dextre moved the STP-H6 experiment from Express Logistics Carrier 3 and attached it to the exterior of the Cygnus NG-16 cargo ship for disposal

On Nov 20 at 1340 UTC Canadarm-2 unberthed the Cygnus, S S Ellison Onizuka, from the Unity nadir port and released it into orbit at 1601 UTC As of Nov 26 the Onizuka remained in a 456 x 464 km x 51 6 deg orbit

On Nov 24 Russia launched the Uzlovoy Modul' (UM No 1L, the node module'), namedPrichal' Prichal has a mass of 4650 kg including about 580 kg of cargo It is attached to a modified Progress, Progress M-UM No 303, which has the normal Progress/Soyuz propulsion section and an adapter docked to Prichal The UM/Progress vehicle docked with Nauka SSVP-M port at 1519 UTC on Nov 26 The Progress will undock later to expose the UM's main docking port

Progress MS-17 undocked again from Nauka at 1122 UTC Nov 25, this time taking the SSVP adapter with it, exposing the SSVP-M docking adapter designed for module dockings The cargo ship was deorbited over the Pacific with debris impact on the ocean at 1517 UTC

Russian ASAT test

On Nov 15 at about 0245 UTC Russia launched a Nudol' suborbital antisatellite missile from Plesetsk The missile intercepted the defunct Soviet satellite Ikar No 39L (codename Kosmos-1408) a few minutes later, possibly at 0250 UTC over about 60E 75N Kosmos-1408 was in a 465 x 490 km x 82 6 deg orbit at the time The intercept occurred at a height of 468 km above the Earth ellipsoid (486 km above the fictive 6378 km spherical Earth used for orbit parameters) The International Space Station passes through resulting debris cloud every 93 minutes, and the crew were instructed to take safety preparations including closing hatches and being ready for evacuation if needed As of this writing, however, there is no evidence of any debris hits from the cloud on ISS

CERES

On Nov 16 Arianespace launched Vega VV20 from the Centre Spatial Guyanais The AVUM upper stage deployed three CERES electronic intelligence satellites operated by the French space agency CNES on behalf of the French defense agency DGA

Electron

Electron flight 22 placed two BlackSky Global imaging satellites in orbit The first stage was lowered to the ocean by parachute; the third stage made a perigee lowering burn to reduce its orbital lifetime

GF11-03

On Nov 20 SAST launched a CZ-4B with the Gao Fen 11 hao 03 xing imaging satellite into an elliptical orbit GF-11 satellites (thought to really be the Jianbing-16 spy sat series) spend several months in such an elliptical orbit before changing to a second mission phase with a circular orbit

Astra Space launched its Rocket 3 3 vehicle (serial LV0007) from Kodiak's Pacific Spaceport Alaska on Nov 20, placing a small non-separating test payload in polar orbit This was Astra's first successful orbital launch The mission, STP S27AD2, was sponsored by the USSF Space Test Program

GF3-02

Gao Fen 3-02, the second GF3 radar satellite from CAST/Beijing, was launched on Nov 22

Shiyan 11

Shiyan 11, a remote sensing satellite built by DFH Shenzhen, was launched by EXPACE on a KZ-1A on Nov 24

Kosmos-2552

An EKS (Kupol/Tundra) infrared missile early warning satellite was launched to elliptical Molniya orbit on Nov 25 The satellite will probably get the cover name Kosmos-2552

SJ-21

Shi Jian 21 and its subsatellite continue to operate in geosynchronous drift orbit, On Nov 15 SJ-21 completed a re-rendezvous with the subsatellite (ejected on Nov 1), approaching and remaining within 5 km of it

Point Arguello - a little history of PALC2-4

There are two separate but physically adjacent spaceports in the Cape Canaveral vicinity: Cape Canaveral Space Force Station and the NASA John F Kennedy Space Center Although they are often conflated, they are owned and operated separately (by Space Force and NASA)

Similarly, from 1959 to 1964 there were two separate, adjacent spaceports on the California coast north of Santa Barbara near Lompoc: Vandenberg Air Force Base and the Naval Missile Facility Point Arguello (NMFPA)

The first space launch from Point Arguello was a Nike-Asp sounding rocket in Jul 1959 from Launch Complex A; the first orbital attempt was the 1960 Oct 11 launch of SAMOS 1 on an Atlas Agena A from Launch Complex 1, Pad 1

Point Arguello's Launch Complex 2, Pad 4 was not used for a launch until August 1964, by which time NMFPA had been transferred to the Air Force and become the South Base section of Vandenberg AFB - the pad was then called Vandenberg AFB PALC2-4 (Point Arguello Launch Complex 2, Pad 4)

Because NMFPA was once a separate spaceport, I still track its pads separately as `South Vandenberg' with site code VS in my launch database (versus site code V for pads on the North Base)

In 1966 the Vandenberg and Point Arguello orbital pads were renamed and PALC2-4 became Space Launch Complex 4-East (SLC-4E) It continued launching Atlas Agena rockets with GAMBIT spysats until 1967; from 1971 to 2005 it was the home for Titan IIID and later Titan 34D and Titan 4

After lying silent for eight years, in 2013 SLC-4E became the West Coast launch site for SpaceX's Falcon 9 So far there have been 17 Falcon 9 launches from the pad

DART

At 0621:02 UTC Nov 24, a Falcon 9 launched from SLC-4E at Vandenberg Space Force Base with the DART (Double Asteroid Redirection Test) spacecraft, sending it to solar orbit Deep space launches are rare from Vandenberg; the first was the Clementine probe, launched on a Titan II from SLC-4W in 1994

Four Atlas V launches from SLC-3E in the 2009-2014 period deployed primary payloads in Earth orbit but then boosted their Centaur upper stages to solar orbit for disposal Most recently, another Atlas V took off from SLC-3E in 2018 carrying the Mars Insight probe

The launch was the first deep space launch from Space Launch Complex 4-East The Falcon 9 headed south from Vandenberg to a 230 x 300 km x 64 7 deg parking orbit After a short coast, the second stage reignited over the Antarctic and boosted DART to a 263 x -135000 km x 64 7 deg escape hyperbola DART and the second stage will depart the Earth-Sun Hill Sphere on Nov 30 at about 0700 UTC, entering a 0 938 x 1 069 AU x 3 8 deg heliocentric orbit on course for the (65803) Didymos system

(65803) Didymos is a 780-metre-diameter asteroid orbiting the Sun in a 1 01 x 1 64 AU x 3 4 deg orbit The half-gigatonne asteroid has a moon, the 163-metre-diameter Dimorphos which has a mass of around a million tonnes and orbits Didymos at a center-to-center distance of only 1 2 km

Didymos then shuttles between the orbit of Mars and the orbit of Earth every 2 1 years But usually when it comes close to Earth orbit, Earth itself is at some other part of that orbit Not this time: Didymos is currently heading inward from aphelion and in Oct 2022 it will reach perihelion passing only about 11 million kilometers from Earth! OK, I know that sounds like a lot, but right now it's 113 million km away

Taking advantage of this close pass, NASA's DART mission will go round the Sun in an orbit just a little bit different from Earth's and reach Didymos just as it passes by Earth DART will reach the Didymos system in Oct 2022 and smash into Dimorphos The impact is expected to change the orbital period of Dimorphos around Didymos by of order ten minutes, something that can be accurately measured, allowing scientists to determine how efficiently the collision imparts momentum to the target rock This information will be crucial in designing missions that could divert a possible future Earth-impacting asteroid

The DART mission is led by JHU's Applied Physics Laboratory (APL) and is managed by NASA MSFC and the NASA Planetary Defense Coordination Office DART has a mass of 500 kg dry It has two propulsion systems: a set of twelve Aerojet Rockedtyne MR-103G thrusters with a thrust of 1N each, fed by 50 kg of hydrazine; and the 7 4 kW NEXT-C ion engine with a thrust of 25 to 235 mN, fed by 60 kg of Xe and powered by two ROSA roll-out solar arrays The main DART spacecraft, built by APL, is 1 2 x 1 3m in size and the deployed ROSA arrays span 19 metres DART has one main instrument, the DRACO (Didymos Reconnaissance & Asteroid Camera for OpNav) imaging camera 10 days before the Didymos encounter it will eject a 6U cubesat, LICIACube The 14 kg LICIACube is built by Argotec for the Italian space agency ASI; it carries two cameras to image the impact

OneWeb

It has been announced that OneWeb satellite SL0041 (catalog 45148) has failed; based on analysis of the orbit uncontrolled decay seems to have set in on about 2021 Feb 24 The remaining 357 OneWeb satellites continue to operate

Epsilon 5

On Nov 9 JAXA/ISAS launched the fifth Epsilon rocket from Uchinoura with a cluster of small satellites The Epsilon third stage entered a 221 x 568 km orbit; the PBS fourth stage then separated and went to a 543 x 572 km orbit Attached to the PBS was the ESMS (Epsilon Satellite Mounting Structure), a large multisatellite dispenser The payloads released from the ESMS were:

RAISE-2, for JAXA, a 110 kg satellite with a series of technology experiments Hibari, for Tokyo Inst of Technology, a 55 kg satellite with an experiment to test attitude control while varying the shape of the craft by deploying a boom Oruri (TeikyoSat-4), a 52 kg satellite bus test for Teikyo U Z-Sat, a 46 kg multispectral infrared imaging satellite for Mitsubishi Heavy Industries DRUMS (Debris Removal Unprecedented Micro Satellite), 46 kg, for Kawasaki Heavy Industries, which will release two 0 13m dia 0 25m long cylindrical targets and attempt to recapture them Asutarisuku (ASTERISC), a 3U cubesat for Chiba Inst Tech with a cosmic dust detector NanoDragon, a 3U cubesat for the Vietnam National Space Centre in collaboration with Meisei Electric Co with an AIS payload and a test of a high performance computer KOSEN-1, a 2U cubesat to observe Jovian radio emission from Kochi Koygo Kosen college ARICA, a 1U cubesat to test a gamma ray burst detector and a rapid alert system, from Aoyama Gakuin U

ZX-1D

China launched a communications satellite to geotransfer orbit on Nov 26 The satellite is codenamed Zhongxing-1D (Chinasat-1D) but is probably a Fenghuo-2 military communications satellite

Solar Orbiter

The ESA Solar Orbiter (SOLO) spacecraft re-entered the Earth's gravitational sphere 1345 UTC Nov 25 and will fly 455 km over the Atlantic at closest approach 0432 UTC Nov 27 SOLO will leave Earth's sphere at 1918 UTC Nov 28 The encounter lowers SOLO's perhihelion to 0 32 AU

Errata

SDGSAT was launched Nov 5 (as in the table), not Nov 3 (as I incorrectly said in the text)

I made some spelling mistakes last issue: the Crew-3 astronauts are Raja Chari (Cdr), Tom Marshburn (Pilot), Matthias Maurer (Mission Specialist 1) and Kayla Barron (Mission Specialist 2)
