Reused Falcon 9 wins NASA launch contract instead of Pegasus

10:04 pm

Captalism in space: NASA has awarded SpaceX a Falcon 9 launch contract using a reused first stage for its next X-ray telescope, the Imaging X-ray Polarimetry Explorer (IXPE)..

SpaceX will charge NASA just over $50 million, its normal price for a reused Falcon 9 and significantly less than NASA has previously paid for this kind of launch. More important, the telescope had been designed with the expectation that it would be launched using Northrop Grumman’s Pegasus rocket. It appears NASA had instead decided to bypass Pegasus, partly because it probably costs more, and partly because there is some issue with Pegasus that has delayed the launch of NASA’s ICON since 2017.

In fact, that ICON launch is the only contract that Pegasus presently has, and it is charging NASA $56 million for that launch, with NASA also having to bear the additional costs associated with the delays caused by Pegasus. All these issues, plus the loss of the IXPE launch, strongly suggests that Pegasus is in big trouble. It does not appear that, as it is presently being marketed, it is able to garner any business.

Comparing today’s modern rocket engines

10:17 pm

For the geeks among us, below the fold is a really really good video describing the engineering designs and considerations that have gone into the launch industry’s most important rocket engines, both now and in the future, with the goal of understanding the design choices SpaceX made for its Raptor engine.

The video is almost 50 minutes long, but if you set the speed at 1.25 you can still understand it and save some time.

SpaceX seeking more investment capital

9:09 am

Capitalism in space: SpaceX has begun its third round of private fund-raising this year, this time seeking more than $300 million.

The latest round, filed on Monday, seeks to raise $314.2 million at a price of $214 a share, according to a document seen by CNBC. The new equity would bring SpaceX’s total 2019 fundraising to $1.33 billion once completed.

The block of this new round appears to already be funded from the Ontario Teachers’ Pension Plan.

SpaceX catches a fairing

7:26 am

Capitalism in space: During last night’s Falcon Heavy launch SpaceX was for the first time able to catch one of the rocket’s fairings using its ship, GO Ms. Tree (formerly called Mr. Steven).

As noted at the link, SpaceX now has in its hands a fairing untouched by salt water that it can analyze for future reuse, something no other rocket company has been able to do. Moreover, that the ship was able to make the net catch at night bodes well for future fairing recoveries.

Falcon Heavy launches successfully

11:52 pm

Capitalism in space: The Falcon Heavy successfully launched tonight, and is presently deploying the 24 satellites on board.

They successfully landed the two first stage side boosters, but the core stage apparently just missed hitting the drone ship in the Atlantic. You could see it come down, but not on the pad. While SpaceX has now successfully recovered all six side boosters on all three Falcon Heavy launches, they have not yet succeeded in recovering the core stage.

The mission’s full success will not be known for several hours, as the satellite deployments unfold. So far the first two satellites have been deployed successfully.

The leaders in the 2019 launch race:

8 China
8 SpaceX
5 Russia
5 Europe (Arianespace)
3 India

The U.S. has now widened its lead over China in the national rankings, 13 to 8.

Falcon Heavy launch a go for 2:30 am (Eastern) tonight

9:57 pm

Capitalism in space: SpaceX’s third Falcon Heavy launch is now a go for launch at 2:30 am (Eastern) tonight.

You can watch it live at SpaceX’s website here or at the embedded video below the fold.

This launch should be especially spectacular, as it will be at night, and the sky is clear. Moreover, they will once again be trying to land all three first stage boosters, with the side boosters flying for the second time only two months after their first flight on the last Falcon Heavy launch.

Schedule for Dragon/Starliner manned flights revised

9:04 am

Capitalism in space: NASA has released a new updated planning schedule for the manned flights of both SpaceX’s Dragon and Boeing’s Starliner manned capsules.

Boeing’s first unmanned demo flight of Starliner is now set for September 17, 2019. This will be followed by SpaceX’s first manned Dragon flight, scheduled for November 15, 2019. Boeing will then follow with its first manned Starliner flight on November 30, 2019.

These are considered target dates. I have great doubts that the Starliner schedule will proceed as described, while SpaceX’s schedule is more likely.

The article also had this interesting tidbit about the upcoming launch schedule of Sierra Nevada’s unmanned reusable cargo ship Dream Chaser:

According to the document, the first flight of Dream Chaser will take place in a planned September 2021 timeframe and will see the vehicle remain berthed to the International Space Station for up to 75 days before returning to Earth to land on a runway for reuse.

There are clearly issues with all these commercial projects. For example, the GAO today released a new report citing the numerous delays in this commercial manned program and calling for NASA to come up with a more complete back-up plan.

Nonetheless, the 2020s have the potential to be the most exciting decade in space exploration since the 1960s. If all goes even close to these plans, the U.S. will have three operating manned spacecraft (Dragon, Starliner, Orion), two reusable cargo spacecraft (Dragon, Dream Chaser), one non-reusable (Cygnus), and a plethora of launch companies putting up payloads of all kinds, from planetary missions to basic commercial satellites numbering in the thousands.

Much could happen to prevent all this. Keep your fingers crossed that nothing will.

SpaceX reschedules manned Dragon demo flight to November

2:46 pm

Capitalism in space: SpaceX has now apparently rescheduled its first manned Dragon demo flight to ISS to no earlier than November 1, 2019.

The information comes from a SpaceX application with the FCC, listing the launch window as sometime between November 1, 2019 and April 30, 2020.

This now gives us the time frame when both NASA and SpaceX expect to complete their investigation into the Dragon test explosion in March as well as institute changes as a result. It also suggests they now have a much better idea what happened and what they need to do, thus allowing them to create this time frame.

Bigelow announces four tourist bookings to ISS using Dragon

8:47 am

Capitalism in space: The private space station company Bigelow Aerospace announced yesterday that it has booked four tourists to spend from one to two months on ISS.

The bookings will fly to ISS using SpaceX’s Falcon 9 rocket and Dragon capsule. Though the company did not say how much these tourists have agreed to pay, it said that it intends to charge $52 million per ticket.

This announcement follows directly from NASA’s announcement last week that it will allow commercial tourist flights to ISS. Previously Bigelow had said it would fly tourists to its own space station using Boeing’s Starliner capsule. Now it is going to take advantage of NASA’s new policy to send the tourists to ISS, and it will use Dragon, probably because Dragon is closer to becoming operational.

I also suspect that Bigelow’s long term plans are to add its own hotel modules to ISS for these flights, and then later follow-up by building its own independent space station.

Astronomers call for regulations to stop commercial satellite constellations

8:12 am

The astronomical community is now calling for new regulations to restrict the number of satellites that can be launched as part of the coming wave of new commercial constellations due to a fear these satellites will interfere with their observations.

Not surprising to me, it is the International Astronomical Union (IAU) that is taking the lead here.

The IAU statement urges satellite designers and policymakers to take a closer look at the potential impacts of satellite constellations on astronomy and how to mitigate them.

“We also urge appropriate agencies to devise a regulatory framework to mitigate or eliminate the detrimental impacts on scientific exploration as soon as practical,” the statement says. “We strongly recommend that all stakeholders in this new and largely unregulated frontier of space utilisation work collaboratively to their mutual advantage.”

When it comes to naming objects in space, the IAU likes to tell everyone else what to do. That top-down approach is now reflected in its demand that these commercial enterprises, with the potential to increase the wealth and knowledge of every human on Earth, be shut down.

The astronomy community has a solution, one that it has been avoiding since they launched Hubble in 1990, and that is to build more space-telescopes. Such telescopes would not only leap-frog the commercial constellations, it would routinely get them better results, far better than anything they get on Earth.

But no, they’d rather squelch the efforts of everyone else so they can maintain the status quo. They should be ashamed.

Dragon cargo capsule successfully returns to Earth

8:01 am

Capitalism in space: After a month docked to ISS SpaceX’s seventeenth Dragon cargo freighter successfully splashed down yesterday.

I think that makes eighteen successful splashdowns. While NASA keeps demanding SpaceX do more tests of its manned Dragon parachute system, which has been made even more robust than the cargo capsule in that it includes four chutes, not three, for greater redundancy, the company keeps demonstrating that they already know how to do this.
