Virgin Galactic is replacing its WhiteKnightTwo mother ship

9:21 am

Virgin Galactic yesterday announced that it has hired Aurora, a Boeing subsidiary, to build two new mother ships to to replace WhiteKnightTwo and launch its SpaceShipTwo suborbital space planes.

Virgin Galactic Chief Executive Officer Michael Colglazier said: “Our next generation motherships are integral to scaling our operations. They will be faster to produce, easier to maintain and will allow us to fly substantially more missions each year. Supported by the scale and strength of Boeing, Aurora is the ideal manufacturing partner for us as we build our fleet to support 400 flights per year at Spaceport America.” [emphasis mine]

The press release claims the first new mother ship will begin operations in 2025.

Forgive me if I am very very skeptical. The highlighted words tell us a lot about this company. First, we now have confirmation that the company has had problems maintaining WhiteKnightTwo. This fact was strongly implied when all planned flights in ’21 and ’22 were cancelled following that first passenger flight in July ’21 in order to do a full maintenance refit of WhiteKnightTwo. This press release tells us that the company’s management has recognized that WhiteKnightTwo cannot be maintained much longer.

Second, the company continues to overhype its future, even without Richard Branson. The chances of it flying 400 times per year, anytime in the near future, is so slim as to be non-existent.

Third, the need to hire an outside company to build these new mother ships also suggests that Virgin Galactic no longer has the capability of doing it itself.

Right now the company’s stock is selling for about $7 per share, well below its initial price of about $12. Expect it to fall again.

SpaceX launches another 53 Starlink satellites

8:38 am

Capitalism in space: Earlier this morning SpaceX successfully launched 53 Starlink satellites, using its Falcon 9 rocket.

The first stage was flying its thirteenth flight, and supposedly landed successfully, though the stage’s video cut off just before landing, the drone ship video did not show it on the pad, and the confirmation of that landing was very late. It is possible it landed on a spot that the camera did not show, or that the landing occurred in the ocean and the stage was lost. We shall have to wait and see.

The leaders in the 2022 launch race:

28 SpaceX
21 China
8 Russia
4 Rocket Lab
4 ULA

The U.S. now leads China 40 to 21 in the national rankings, and the entire world combined 40 to 35.

Having regained communications with CAPSTONE, engineers prepare for first mid-course burn

8:55 pm

Engineers are now preparing CAPSTONE for its first first mid-course engine burn, slightly late due to a loss of communications during the past two days.

The spacecraft is in good health and functioning properly.

The CAPSTONE team is still actively working to fully establish the root cause of the issue. Ground-based testing suggests the issue was triggered during commissioning activities of the communications system. The team will continue to evaluate the data leading up to the communications issue and monitor CAPSTONE’s status.

If all goes well, that engine burn will occur as early as 11:30 am (Eastern) on July 7th.

How did sand dunes get to the top of a Martian mesa?

1:51 pm

Sand dunes at the top of a Martian mountain
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on January 1, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and shows one of the peaks of a 5,000+ foot high mesa inside Juventai Chasma, one of Mars’ deep mostly-enclosed chasms north of Valles Marineris.

I grabbed this picture because its label, “Bedform Change Detection in Juventae Chasma”, suggested something had changed from past photos, probably related to the sand dunes that hug the upper slopes of this peak. Unfortunately, in comparing this image with the earliest high-res image taken by MRO back in February 2018, I could not spot any change, probably because the resolution of the pictures released is not as high as MRO’s raw images.

However, the caption written for that 2018 image tells us where that change has likely occurred:

This image reveals a unique situation where this small dune field occurs along the summit of the large 1-mile-tall [mesa] near the center of Juventae Chasma. The layered [mesa] slopes are far too steep for dunes to climb, and bedform sand is unlikely to come from purely airborne material. Instead, the mound’s summit displays several dark-toned, mantled deposits that are adjacent to the dunes and appear to be eroding into fans of sandy material.

In other words, somewhere in the full resolution image scientists have spotted a change in the bedform sands that make-up these high mountain dunes that hug the peak. Since the data so far has suggested that the source for the sand of these high elevation dunes likely comes from the mesa itself — not from any distant source — any change found will help confirm or disprove that hypothesis.

The white box indicates the area covered by the close-up higher resolution picture below. Also below is an overview map, showing both the location of this mountain in Juventai Chasma as well as Juventai’s location relative to Valles Marineris.

Today’s blacklisted American: Google blacklists Republican Party fund-raising emails

12:24 pm

Google: a place that loves to censor

Blacklists are back and Democrats at Google have got ’em: According to evidence presented by the Republican National Committee last week, Google is tactically blocking all fund-raising emails from the committee at the end of the month, when such emails are routinely sent.

To quote the twitter thread from Ronna McDaniel, GOP chairwoman:

Every single month – for 7 months in a row – Google has systematically attacked the RNC’s email fundraising during important donation days at the end of the month. Our emails go from strong inbox delivery (90-100%) down to 0%.

These are emails that go to our most engaged, opt-in supporters without any increase in user complaints, changes to the content, email frequency or target audiences that could account for the suppression.

Yet month after month – like clockwork – right ahead of a CRITICAL period when voters are most engaged, Google blocks our emails. They even block GOTV emails.

Google has failed to explain why this is happening. It’s unacceptable. We have filed a complaint with the FEC over this practice of censoring Republican emails and it just keeps happening.

The graphic below, including in McDaniel’s tweets, shows how the GOP’s emails are suddenly considered spam by Google at the end of every month, conveniently at the very moment the party sends out its fund-raising pleas.

China begins construction of commercial spaceport

9:39 am

The new colonial movement: China’s state-run press today announced the ground-breaking of a spaceport on the southern island of Hainan that will be dedicated to launches by that country’s pseudo-commercial companies.

The location is in Wenchang City, the same location of the country’s Wenchang spaceport used to launch government’s newest Long March rockets. While it isn’t clear from the Chinese news report, this new facility is likely at the same location.

Though China touts this as a commercial facility for private commercial launch companies, everything in China is still controlled and owned by the government. Nothing will happen at this new site that China’s military does not approve.

Rocket Lab to launch twice in 10 days for NRO

9:11 am

Capitalism in space: Rocket Lab announced yesterday that its next two launches, scheduled for July 12th and July 22nd, will demonstrate the ability of the company to quickly launch reconnaissance satellites for the National Reconnaissance Office (NRO).

The NROL-162 and NROL-199 missions will carry national security payloads designed, built, and operated by the National Reconnaissance Office in partnership with the Australian Department of Defence as part of a broad range of cooperative satellite activities with Australia. The satellites will support the NRO to provide critical information to government agencies and decision makers monitoring international issues.

These twin missions will be a demonstration of responsive launch under NRO’s Rapid Acquisition of a Small Rocket (RASR) contract for launching small satellite through a streamlined, commercial approach, and are the third and fourth missions contracted to Rocket Lab by the NRO under the contract.

Several federal military agencies have been testing this capability with almost all the new rocket companies, from the large, such as SpaceX, to the small, such as Rocket Lab and Astra.
