Beautiful ground footage of the CRS-15 launch

USLaunchReport, a disabled veteran-run enterprise on Florida’s Space Coast, provides ground footage of launches, and they got some beautiful footage of this one.  Skip ahead about four minutes to staging, where it’s up high, lit by the Sun, and the humid air near the ground is less of an obstacle to photography, and watch to the end when they start to cut in shots of the plume in the background and in the foreground you can see the impressive optical tracking system they got to use for this:

Final Block 4 Falcon 9 Flies with Dragon

The last Block 4 Falcon 9 flew yesterday, boosting an unmanned Dragon capsule to the ISS for the CRS-15 mission (skip to about 18:50 for the launch):

Since this was the final Block 4 flight, SpaceX did not attempt to recover the booster.  This was, however, its second flight; Core 1045 helped launch the TESS satellite on April 18, which is just a 72 day turnaround to its second flight, SpaceX’s fastest reflight to date.

Unpressurized cargo includes the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) for JPL and a replacement latching end effector for the SSRMS.  Pressurized cargo includes:

  • Chemical Gardens (a crystal growth experiment)
  • an experimental carbon fiber “factory” for the private company Made In Space (the third one flown to date)
  • Crew Interactive Mobile (CIMON), a floating spherical robot trained to recognize and interact with European crewmember Alexander Gerst.
  • Rodent Research 7, which will study microorganisms in the guts of a colony of “mouseonauts”
  • BCAT-CS, a sediment research project
  • Three Cubesats called Biarri-Squad for a multinational experiment to study potential military applications for smallsats (these will be experimenting with laser rangefinding and GPS to maintain relative position data)
  • Three CubeSats from the Japanese-led multinational Birds-2 project performing a range of technology demonstrator experiments
    • One of the Birds-2 CubeSats is Bhutan-1 (aka Bird BTN), the Kingdom of Bhutan’s first satellite
    • Another is Bird PHL or Maya-1, the first Filipino CubeSat (not their first satellite

The Dragon Flies Again: CRS-14 Launches to the ISS

A reused Dragon capsule launched by a reused Falcon 9 first stage is now en route to the ISS.  The first stage was not recovered; it’s one of the older model stages, and SpaceX sacrificed it in order to conduct engineering tests during a water landing.  There was no attempted fairing recovery, as the Dragon capsule does not require a fairing.  But the launch was 100% successful:

Dragon is expected to rendezvous with the station on Wednesday, where it will go free-floating and be captured by the station’s SSRMS, which will pull it in to berth.

Launch/Landing Recap — plus SpaceX and Electron status

I’m still way too busy to post every day, so in penance, here’s the last month worth of things going up and things coming back down! The vast majority of these are Chinese — they’ve been extremely busy lately!

On November 14, a Long March 4C blasted off out of Taiyuan, China with the Fengyun 3D weather satellite on board.

Then on November 18, the penultimate Delta II launched.  I already posted a link to a full-length video, so now here’s ULA’s traditional launch highlights video:

On November 20, a Long March 6 blasted off from Taiyuan, China with the Jilin 1 set of Earth observation microsatellites.  These are commercial satellites offering real-time video of the Earth, so I chose this launch video because although it doesn’t show very much of the launch, it does include some of the first images returned by the three spacecraft:

Four days later, China launched another rocket, a Long March 2C out of Xichang, with the Yaogan 30-02 photo reconnaissance cluster of three spacecraft:

On November 28, the Vostochny Cosmodrome finally hosted its second flight, a Soyuz 2-1b carrying the Meteor M2-1 weather satellite and a collection of smaller payloads.  Unfortunately, in another bit of bad news for the cosmodrome (and through circumstances beyond their control), the launch was a failure.  The Fregat upper stage was programmed incorrectly, leading to a failure to insert into orbit.  The spacecraft are believed to be somewhere in the Pacific Ocean.

On December 2, however, the Soyuz 2-1b had a chance to redeem itself, succesfully placing the Lotos-S1 spacecraft, believed to be an electronic intelligent satellite, into orbit from Plesetsk Cosmodrome.  This was the first launch of this Soyuz variant from Plesetsk:

And then later the same day, a Long March 2D placed the Yaogan Weixing/LKW-1 Earth observation satellite into orbit from Jiuquan, China:

On December 10, China followed that up with a Long March 3B out of Xichang, placing Alcomsat 1 into orbit.  Alcomsat is a commercial geosynchronous commsat for the nation of Algeria:

And on December 12, an Ariane 5 carried the next four Galileo satellites, (spacecraft 19-22) into orbit from Kourou, French Guiana:

And the last launch on this list isn’t an orbital one: it’s another suborbital (and, technically, just barely sub-space) flight of the fully reusable New Shepherd rocket with the new version of their capsule, with super large windows:

They also, for the fist time, had a simulated passenger on board: a crash test dummy nicknamed Mannequin Skywalker.  Here’s his view:

Lastly, one more thing coming back down: the Soyuz MS-05 spacecraft, following a successful six-month stay at the International Space Station, carrying Sergey Ryanzanskiy, Randy Bresnik, and Paolo Nespoli:

There were two other launches scheduled this week.  The first, Rocket Lab’s second attempt to test fly their Electron small rocket out of New Zealand, was aborted seconds after main engine start a few days ago.  Last I heard, they were trying for a launch today, but I have not yet heard if they flew.  (Which I think means they have not attempted another launch yet.)

The second is SpaceX’s latest CRS flight to the International Space Station, and the first where NASA has permitted the use of a reused first stage on the rocket.  Also, the return to flight for SLC-40 after the catastrophic loss of a Falcon 9 and Dragon there about a year ago.  They had a successful test fire, but technical concerns have delayed the launch.  It’s currently set for late Friday morning.  If they miss that launch time, however, they may have to stand down for a while.  The next crewed Soyuz is scheduled to launch on Sunday, and after that the thermal environment will be unfavorable for docking due to the sun angle.  Next attempt would likely be no earlier than Christmas Day.

ISS Status Update: Cargo Craft Coming and Going

The ISS is going into another busy period with upcoming cargo ship movements.  First off, the latest Cygnus spacecraft, SS Gene Cernan, was unberthed and released to fly on its own.  SS Gene Cernan now moves into the second part of its mission: deploying nanosatellites, conducting another fire test (Saffire-III, the third and final in the series), and then deorbiting itself safely over the ocean.

The next bit of news is SpaceX preparing for their next flight to the ISS.  This will mark the return to flight of LC-40, the Cape Canaveral launchpad that was badly damaged in a Falcon 9/Dragon mishap last year.  Liftoff is currently scheduled for December 12, and their traditional pre-flight test fire was conducted yesterday, reinaugurating LC-40’s flame trench (skip ahead two minutes for the fire):

Launch/landing updates

It’s been a while since I’ve posted; work’s been crazy busy!  So I’ll quick catch you up with some of what’s gone up and down since I last posted:

On September 17, the latest Dragon capsule (CRS-12) returned from the ISS with a two tons of research material and hardware on board, including a population of laboratory mice sent into space to study effect on eyesight and movement.

On September 21, a Soyuz rocket from Plesetsk Cosmodrome placed the latest element of the GLONASS M navigation constellation into orbit.

On September 23, an Atlas V out of Vandenburg Air Force Base carried the classified NROL-42 into orbit for the National Reconnaissance Office.

Obviously, they won’t tell us much about the payload, but the mission patch and the launch site both suggest a polar orbiting spacecraft.  The size of the fairing and quantity of boosters both suggest a very big spacecraft, which is fairly typical for spy satellites.  It is believed to be a signals intelligence spacecraft, which means its job will likely be to intercept communications.  Maybe.  😉

Lastly, the Tianzhou 1 spacecraft returned to Earth in pieces last Friday.  It was supposed to; it was an experimental robotic resupply and refueling spacecraft similar in function to Progress, which also undergoes a destructive reentry at the end of its mission.  Tianzhou 1 completed a successful mission docking with the uninhabited Tiangong 2 space station, transferring propellant, and then later undocking and safely disposing of itself.  Tiangong 2 is not expected to host any more human occupants, but remains in orbit as a procedures testbed for ground controllers.  It is not clear when the next space station will fly; China intends to greatly increase the size and functionality of their stations, but they have had a major setback with the failure of the last Long March 5 rocket.  This is the heaviest rocket they’ve built to date, and is intended to place the major elements of their new modular space station in orbit, but with a 50/50 operational record after two flights, some more work is needed before it can carry such valuable cargo.

CRS-12 successfully launched!

A Falcon 9 rocket successfully delivered the CRS-12 Dragon capsule to Earth orbit today, complete with a successful return of the first stage to Cape Canaveral.  It carries 3642 lbs. / 1652 kg of cargo in its pressurized compartment, and the 2773.4 lbs. / 1258 kg CREAM experiment package in the unpressurized “trunk” section.  (At around 10:27 of the following video, you can start to see CREAM in Dragon’s back section, complete with RMS grapple fixtures that will be used to extract it from the trunk later on.)  CREAM, Cosmic-Ray Energetics And Mass, has been flown from stratospheric balloons already; mounting it on the JEM Exposed Facility will give it the opportunity to make far more measurements over a long period of time.  Of more immediate practical return are the experiments in the pressurized compartment, including a crystal growth experiment funded partly by the Michael J Fox foundation to study Parkinson’s Disease, a commercial microsatellite to be deployed later, and an experiment that will grow human lung cell tissue scaffolds to be used in pharmaceutical and biological research.
