Catching up on launches and landings!

I’ve been remiss in blogging, so here’s a pile of videos to try to make it up. ¬†ūüėČ

First off, last Saturday China carried out the second launch of their new heavy-lift rocket, the CZ-5 (Long March 5), from their newest launch site on Hainan Island. ¬†CZ-5 is intended to support their deep space exploration aspirations, including eventual manned missions to the Moon, so a successful launch was very important. ¬†Unfortunately, it does not appear to have been successful. ¬†Initial indications suggest the first stage burned considerably longer than expected, which would suggest a possible engine failure resulting in the stage burning much longer in attempt to compensate, perhaps to propellant depletion. ¬†The second stage appears to have carried out a normal burn, but was clearly unable to make up the velocity shortfall. ¬†The upper stage and its seven-ton experimental commsat payload (Shijan-18) both reentered, most likely impacting in the Pacific Ocean. ¬†The strap-on stages of the CZ-5 operate on kerosene and LOX, while the core and upper stages burn LH2/LOX. ¬†The booster engines use a design licensed from NPO Energomash in Russia, the world’s undisputed leader in staged-combustion kerolox engines (it really is amazing how many vehicles around the world use their designs), while the cryogenic engines are domestically designed and produced.

Meanwhile, the first recycled SpaceX Dragon capsule completed its mission to the ISS. ¬†One of its payloads was the Roll-Out Solar Array (ROSA), an experiment to test a new type of solar array that is more robust than earlier roll-out designs (remember Hubble’s original arrays, which usually looked a bit twisted and wonky when deployed?) but more compact than rigid arrays. ¬†The experiment was almost a complete success, with the array generating lots of power. ¬†Unfortunately, retraction was unsuccessful, so the array had to be jettisoned in its deployed state.

The ROSA’s ride up also left the ISS, but in a more controlled fashion, and returned to Earth.

The CRS-11 spacecraft then made the first Dragon reentry at night.  Astronaut Jack Fisher photographed the plasma trail from orbit:

Rounding out the launches of the last few days is today’s launch of the tenth Falcon 9 of the year, placing Intelsat 35E into geosynchronous transfer orbit. ¬†Due to the size of the payload, this was flown as a fully expendable launch vehicle, with no grid fins and no excess propellant margin to carry out a reentry burn:

CRS-11 Launch: First reused Dragon capsule has flown

The CRS-11 Dragon mission is now underway, the first with a reflown Dragon capsule.  (The heatshield is new, as of course is the unpressurized trunk section and the solar panels, as these are discarded with each flight, burning up while the pressurized module returns to the Earth.)  The Falcon 9 rocket was still brand-new, but the first stage will eventually be reused; it completed the fifth successful landing at Cape Canaveral.

This was the one hundredth launch from LC-39A.

Here’s the replay of the SpaceX webcast (jump ahead 16 minutes for the launch):

SpaceX could be the next to send humans to the Moon???

Yes, you heard that right. ¬†They have yet to launch their crewed spacecraft as far as the ISS, but this week they announced that two undisclosed wealthy individuals have approached them about riding a Dragon capsule, boosted by their soon-to-fly Falcon Heavy, in a trip around the Moon. ¬†(I’m betting they’re talking a lunar swingby mission, not an orbital mission.) ¬†They plan on conducting this mission by the end of 2018.

For perspective, there are only two flights of Falcon Heavy currently on the manifest (the demo launch and a USAF experimental mission, one this year and one the next), and the crewed Dragon isn’t set to fly to the ISS until the fourth quarter of 2018 as it is. ¬†(And the GAO recently expressed serious doubt about that even happening.) ¬†So this is pretty ambitious. ¬†Exciting, and very very cool, but certainly a stretch goal.

Who are the two individuals? ¬†SpaceX isn’t saying. ¬†They did, however, say they’d be happy to give NASA dibs on flying to the Moon aboard Dragon first — an announcement which came as a great shock to NASA, since they found out about all of this the same time the rest of us did.

This is sure to shake things up, and I’d not put odds on whether or not they’ll manage this. ¬†I do have to wonder whether they’re overextending themselves. ¬†They have put a lot of very ambitious challenges in front of themselves. ¬†From a program risk perspective, this doesn’t seem like a good idea. ¬†But if they pull it off . . . hoo boy. ¬†There’s quite a payoff in terms of bragging rights, and it’s definitely a strong step towards their ultimate goal: Mars.

Dragon arrives at ISS, and Progress begins its climb

The cargo trips to the ISS continue, with the CRS-10 Dragon arriving a day late (after waving off the first rendezvous due to faulty GPS data) and Progress MS-05 blasting off and returning the Progress capsule to flight after the unfortunate launch vehicle failure that destroyed the last one.  Progress Ms-05 also capped off the venerable Soyuz-U, as it was the final flight of that rocket variant.

Dragon has been berthed at the nadir port of the Harmony node, and Progress MS-05 is en route to dock with the nadir port of the Pirs compartment.

The Falcon has landed — after lifting off from the same pad as Apollo 11!

This morning, a Falcon 9 rocket roared into space from Kennedy Space Center’s LC-39A, the first commercial launch to lift off from this NASA launch facility. ¬†(Previous Florida launches of the Falcon 9 were from the neighboring Cape Canaveral Air Station, operated by the USAF.) ¬†Fittingly, this was still a NASA mission; the payload is the CRS-10 Dragon cargo mission to the International Space Station. ¬†But the next flight won’t be; the next flight will¬†deliver the EchoStar 23 commercial commsat to geosynchronous transfer orbit.

LC-39A was originally built to support launches of the gigantic Saturn V for the Apollo mission, and so everything is proportionately gigantic on this pad.  Falcon 9 is the smallest rocket ever to fly from it, but later it is planned to support the massive Falcon Heavy, a triple-core variant that will be the most powerful rocket in the world when it flies, and that is the real reason for using this pad.

Today’s mission was completely successful, including the first daylight shore landing of a Falcon 9 first stage. ¬†That stage landed on the existing SpaceX landing pad at Cape Canaveral. ¬†And there’s some great footage. ¬†ūüėČ

And here is spectacular drone photography of the landing:

LC-39A: Bringing the Heat Back

As part of routine preparations for the upcoming Dragon flight to the ISS, SpaceX has also passed a historic milestone: allowing the flame trench at LC-39A to taste fire again.

Ignition is around two minutes into the video.  Several things to note in this video: the extra-large Falcon 9 strongback, designed to support the Falcon Heavy, the Shuttle-era hardware still resident (particularly the Fixed Service Structure and Rotating Service Structure, although both have been stripped of most of their equipment, as well as the huge Apollo-era water tower for the sound suppression system), and the distant white shape of the SpaceX Falcon 9 assembly building at LC-39A.  Never before have rockets been assembled at LC-39A; the pad was built for the gigantic Saturn V, which was assembled in the VAB and then ponderously rolled to the pad, and then the same strategy was employed for the Space Shuttle program.  But Falcon 9 is a much simpler vehicle, and does not require such a large assembly hall as the VAB.

The Falcon 9 hotfire test concluded successfully. The vehicle will be lowered and pulled into the assembly hall for attachment of the Dragon spacecraft.  After returning to the pad with payload installed, Falcon 9 is slated to lift off February 18 on a mission to the ISS, returning LC-39A to service for the first time since 2011.  SpaceX has additional flights already manifested for LC-39A; the next will be EchoStar 23 no earlier than February 28, and SES 10 sometime in March.  The SES 10 launch will be closely watched, as it will feature the first reflown Falcon 9 core.

Just for fun reference, here’s the last flight from LC-39A:

IDA-2 is ready for installation!

The first of two International Docking Adapters (designated IDA-2 since IDA-1 was lost in the one and only Falcon 9 launch mishap to date) has, by now, been extracted from the trunk of the CRS-9 Dragon spacecraft and should be hovering about three feet away from the Pressurized Mating Adapter 2 (PMA-2) on the forward end of the ISS, secure in the grip of the SSRMS. ¬†It will stay there until Friday, when astronauts Jeff Williams and Kate Rubins will exit the Quest airlock and work to get the adapter properly installed. ¬†NASA has released this wonderful informative CGI video outlining the plan for Friday’s spacewalk.

If you want to watch it live, tune in to NASA TV (via cable, satellite, YouTube, the NASA TV website, or wherever else you can find a feed) on Friday.  Live coverage starts at 6:30 AM EDT (10:30 UTC), and the actual spacewalk is scheduled to begin at 8:05 AM EDT.
