First very short movie from Jupiter

7:37 am

Using two Juno images of the same area, taken at slightly different times, scientists have produced what might be the first very short gif animation showing the changing circulation patterns in Jupiter’s atmosphere.

The animation is only two images long, so in a sense it isn’t a movie but a blink comparison. Moreover, the difference in circulation patterns between the two images is not strongly evident, partly because the two images have different resolution and somewhat different lighting. Nonetheless, this animation foretells what will should become possible with time, as Juno’s mission continues. Eventually its images will show the changes in the gas giant’s storms.

Cassini’s last five orbits of Saturn

10:14 pm

Cassini is about to begin its last of five orbits of Saturn, before it is sent into the planet’s atmosphere to burn up.

Cassini will make the first of these five passes over Saturn at 12:22 a.m. EDT Monday, Aug. 14. The spacecraft’s point of closest approach to Saturn during these passes will be between about 1,010 and 1,060 miles (1,630 and 1,710 kilometers) above Saturn’s cloud tops.

The spacecraft is expected to encounter atmosphere dense enough to require the use of its small rocket thrusters to maintain stability – conditions similar to those encountered during many of Cassini’s close flybys of Saturn’s moon Titan, which has its own dense atmosphere. “Cassini’s Titan flybys prepared us for these rapid passes through Saturn’s upper atmosphere,” said Earl Maize, Cassini project manager at NASA’s Jet Propulsion Laboratory (JPL) in California. “Thanks to our past experience, the team is confident that we understand how the spacecraft will behave at the atmospheric densities our models predict.”

Looking down at Saturn’s rings

9:19 am

Looking down at Saturn's rings

Cool image time! The image on the right, reduced in resolution to show here, was taken by Cassini in May and looks down at the outer rings of Saturn. The moon Prometheus can also be seen in the large gap between the main rings and the outermost F ring.

Most of the small moon’s surface is in darkness due to the viewing geometry here. Cassini was positioned behind Saturn and Prometheus with respect to the sun, looking toward the moon’s dark side and just a bit of the moon’s sunlit northern hemisphere.

Also visible here is a distinct difference in brightness between the outermost section of Saturn’s A ring (left of center) and rest of the ring, interior to the Keeler Gap (lower left).

The image clearly shows the gravitational influence of the moon on the outer ring. As Prometheus orbits past the F ring its mass creates waves through the ring’s materials.

Webb telescope launch might be delayed again

8:59 am

Because of a scheduling conflict with a European mission to Mercury Arianespace might delay its launch of the American James Webb Space Telescope to 2019.

A time-sensitive mission to explore the planet Mercury, already delayed several times, may force the European Space Agency (ESA) and Arianespace to push back the launch of NASA’s multi-billion dollar James Webb Space Telescope (JWST) into early 2019. The mission, named BepiColombo, is currently scheduled to launch on the same rocket, the Ariane 5, from the same spaceport in French Guiana, during the same timeframe that the JWST is scheduled to launch (October 2018).

A launch delay to BepiColumbo won’t impact the science of the ESA/Japan Aerospace Exploration Agency (JAXA) mission, but it would translate to a longer journey to Mercury. The last launch delay, which pushed it from April 2018 to October 2018, also translated to a year longer voyage to reach Mercury, now expected to arrive in 2025 instead of 2024.

This is a perfect illustration of the difference between governments and private enterprise. Government-owned Arianespace has been flying its Ariane 5 rockets now for almost two decades, but they have not yet learned how to launch two rockets in one month, and don’t appear interested in trying. Meanwhile, private companies like SpaceX and ULA are both working to achieve a normal twice-a-month launch rate, with SpaceX likely to beat that in the next few years.

Ground equipment caused premature end to first Rocket Lab launch

8:51 am

Capitalism in space: Rocket Lab’s first test flight of its Electron rocket in May was terminated early because of a loss of communications due to an “misconfiguration” of ground telemetry equipment.

The company said the fix for the issue was “simple” and that “corrective procedures” were put into place to prevent it from happening in the future. Rocket Lab said it did not make any major changes to the Electron hardware.

No word on when their second test launch will take place. For their Moon Express customer, the clock is ticking, as that company is a Google Lunar X-prize contestant that needs to launch its lunar rover before the end of this year to have a chance at winning the prize.

SES agrees to a second Falcon 9 launch with used first stage

6:46 pm

Capitalism in space: SES has agreed to launch a second commercial satellite using a previously flown Falcon 9 first stage.

The launch of the SES 11 spacecraft, also named EchoStar 105, will be the third time SpaceX has sent a customer’s satellite into orbit with the help of a reused rocket stage. Industry officials said SES, EchoStar and SpaceX agreed in recent weeks to shift the satellite from an all-new rocket to one with a previously-flown first stage. The SES 11/EchoStar 105 satellite will likely ride a Falcon 9 first stage that first flew Feb. 19 with a Dragon supply ship heading for the International Space Station, one source said, but a firm assignment has not been confirmed. That vehicle returned to a vertical touchdown at Landing Zone 1 at Cape Canaveral Air Force Station.

Liftoff from a Florida launch pad is scheduled no sooner than around Sept. 27, a couple of days after a United Launch Alliance Atlas 5 rocket is set to haul a classified payload into orbit for the National Reconnaissance Office, the U.S. government’s spy satellite agency.

The most wonderful aspect of this is how routine it is steadily becoming.

One of Jupiter’s mid-sized storms

8:54 am

One of Jupiter's mid-sized storms

Cool image time! The Juno image on the right, cropped to show here, focuses in on one of Jupiter’s mid-sized storms near its high northern latitudes and just on the edge of the chaotic polar region.

This storm is a long-lived anticyclonic oval named North North Temperate Little Red Spot 1 (NN-LRS-1); it has been tracked at least since 1993, and may be older still. An anticyclone is a weather phenomenon where winds around the storm flow in the direction opposite to that of the flow around a region of low pressure. It is the third largest anticyclonic oval on the planet, typically around 3,700 miles (6,000 kilometers) long. The color varies between red and off-white (as it is now), but this JunoCam image shows that it still has a pale reddish core within the radius of maximum wind speeds.

Be sure to take a look at the full image, which provides a bit of context.

International group forms to get UN protection of Apollo sites

8:43 am

An international group of lawyers, academics, and business people has formed an organization called “For All Moonkind,” aimed specifically at getting UN protections for the six lunar Apollo sites.

They are going to the UN because, based on the Outer Space Treaty, this is the only place that has jurisdiction. Unfortunately. This quote illustrates why:

“Though we are based in the US, we are an international organization,” said Michelle Hanlon, US space lawyer and Co-Founder of For All Moonkind. “Humaid Alshamsi [the UAE participant] brings tremendous experience in public and private aviation and space law to our team. We are thrilled that he has agreed to join our effort.”

For All Moonkind was critical of the auction by Sotheby’s of the Apollo 11 Contingency Lunar Sample Return Bag used by astronaut Neil Armstrong. “The astronauts of the Apollo project represented all of us here on Earth,” explained aviation and space lawyer and Advisory Council Member Humaid Alshamsi, “they went to the Moon in peace for all, and the relics of their historic achievement should be shared by all. The loss of this artifact to a private collector is a loss for humanity.”

The Outer Space Treaty forbids any nation from claiming territory in space, thus leaving it under the control of the UN and the international community, a community that — as demonstrated by this quote — is hostile to capitalism and private enterprise. While I laud this group’s desire to protect these historic sites, I fear their actions are going to place limits on the freedoms and property rights of future space colonists.

New images downloaded from Curiosity for the first time in two weeks

9:15 am

For the first time since communications with Mars ceased two weeks ago because the orbits of the Earth and Mars had placed the Sun in between, new images have been downloaded from Curiosity.

For the past two weeks, the last raw images posted had been from sol 1760. Today, the Hazard Avoidance Cameras (Hazcams) added daily images through sol 1774 (taken as per previously uploaded commands). The images all show the same view, the part of Vera Rubin ridge that the rover has been circling around to get to the place where it will be easier to climb up. The science team probably programmed this sequence so that they could look for any changes from wind, over time.

No new images from either Curiosity’s other cameras or from Opportunity have yet appeared, but I expect this to soon change.

India to almost double launch rate with new rocket assembly building

9:01 am

Capitalism in space: India’s space agency ISRO is building a second rocket assembly facility at its Sriharikota spaceport so that it can prepare two rockets for launch simultaneously.

“We have not reached the limit of two launchpads. With the new assembly facility, we will be able to assemble more vehicles. Once we are able to assemble more rockets but not able to launch them even by reducing launch timings, then we will start work on the third launchpad. But for that, we first need (government’s) approval. So, we are gradually working to eliminate all bottlenecks to increase the frequency of launches.” With the new facility, Isro can achieve launch 12 rockets in a year from the seven at present.

The Times of India also recognizes the value of this upgrade. To quote the article, “With the increased frequency of foreign satellite launches, ISRO can rake in big moolah.”

I couldn’t have said it better myself.

Vector live streaming test launch

8:53 am

Capialism in space: If you want to watch today’s test launch by Vector, the company is live streaming the event.

As I post, the rocket is vertical in a small clearing surrounded by woods, with a small group of workers at its base.

Update: One minute to launch.

Update: Launch at 9:25 am. The rocket cleared the tower perfectly. We will have to wait for updates from the company to see how things went beyond that.

Lockheed Martin begins construction of new satellite factory

7:12 pm

Capitalism in space: Lockheed Martin has begun construction of a $350 million satellite factory in Colorado, with expected completion in 2020.

At the moment, Lockheed does not have a competitive rocket. Moreover, its only big space project is Orion, which might never fly more than twice, if that. Thus, this shift to satellites makes some sense, as it will be difficult now for the company to gain market share in the launch and manned spacecraft markets. It is too far behind. However, there is a new industry developing in smallsats, and Lockheed is well positioned to get in at the start.

Update: I do this all the time, but I made a mistake here and assigned the Delta family of rockets to Lockheed Martin. For some reason I make this mistake often, switching Atlas 5 and Delta and Lockheed Martin and Boeing. I apologize for the error.

An explorer’s club for Mars missions

9:24 am

An international group based in New Zealand has put together a new organization, dubbed the Martian Trust, modeled after National Geographic as a way to privately fund space missions.

The Martian Trust is similar to the early National Geographic Society, a non-profit which funded exploration of the world’s furthest reaches through everyday members, magazine subscribers, and wealthy philanthropists. The intent is to tap into the global space-lovers, who will help fund projects in exchange for martian stories, products and experiences produced.

They are using crowd-funding to obtain funds. Trustees will be picked either by a vote from those who contributed small amounts, or because they themselves contributed more than $5 million.

Virgin Orbit’s launch jumbo jet arrives at company’s base in California

9:19 am

Capitalism in space: The modified jumbo jet that Virgin Orbit is going to use as the first stage of its LauncherOne rocket, being designed to put smallsats into orbit, arrived yesterday in Long Beach to put it close to the company’s base of operations.

While some of this story is the typical hype we all should expect — and question — from a company run by Richard Branson, Virgin Orbit looks more like the real thing. Last year it was separated from Virgin Galactic, the company that has been promising and failing to fly tourists on suborbital flights now for more than a decade. I suspect this happened because the LauncherOne group did not want to be saddled any longer with the failures of the SpaceShipTwo group.

I have been predicting that LauncherOne will reach space before SpaceShipTwo, and this story only adds weight to that prediction. They have real satellite contracts, and expect their first launch to occur in 2018. While that schedule might not hold, I suspect it will not be far wrong.

Booking service now available to rocket and satellite companies

9:41 am

Capitalism in space: A new company, Precious Payload, is now offering a booking service to both rocket companies and satellite manufacturers to make it easier to match them together.

In the Precious Payload concept, launch providers and brokers share and exchange their immediate and future availability of inventory with the independent Precious Payload GDS, including the status of reservations of inventory (eg. available, reserved, booked, etc.).

Anyone who wants to launch a satellite uploads their mission profile into the Precious Payload GDS. A special algorithm then analyses the data and shows the real-time availability of launchers for specific types of mission.

Launch providers, both manufacturers and brokers, can benefit from the Precious Payload GDS by being able to open another sales channel for their core businesses. They not only receive and process the booking requests from satellite companies, but also browse through the backlog of satellites waiting for launch and bid for their business. Advanced services like rebooking the launches and effectively managing client cancellations and launch failures raise the bar for customer experience in the market.

To pitch their product, they are presently offering their initial service for free.

Next test flight of Rocket Lab’s Electron rocket delayed

9:34 am

Capitalism in space: Rocket Lab has revealed that the second test flight of its rocket Electron is still several months away.

Rocket Lab is in the early stages of a three-vehicle test programme and Moon Express is still developing its lander at its facilities at Cape Canaveral, from where Apollo missions were launched. Rocket Lab’s first test launch successfully made it to space in late May. The first stage performed as it should but the second stage failed to deliver the payload to orbit.

Results of data analysis from the test flight could be available some time next week.

Earlier this month Rocket Lab founder Peter Beck said the company and its investors had confidence in the programme and they had another five rockets in various stages of production.
Beck said then a second test launch was about two or three months away and the company hoped to get its commercial launches underway as soon as it was satisfied with the test programme.

The company had previously said it hoped to launch the second test flight in mid-2017. It appears now that the second launch will not happen before October.

The article is strangely focused on selling the idea that Moon Express’s Google Lunar X-Prize flight, which must occur by the end of this year, is still on track. I don’t see how, with this news. Rocket Lab must first complete its three test flights, and I don’t see how they can do this, get their results, and update their engineering and still get this first commercial flight off by December.

Solid gold Apollo 11 lunar module replica stolen from Armstrong museum in Ohio

9:23 am

On Friday thieves broke into the Neil Armstrong Museum in Ohio and stole a solid gold miniature replica of the Apollo ll lunar module that had been one of three gifted to the three astronauts in Paris during their post-flight world tour.

Police responded to a burglary alarm at the Armstrong Air and Space Museum in Wapakoneta, Ohio, shortly before midnight on Friday (July 28), where the 18 karat gold, five-inch-high (13 centimeter) miniature lunar lander was found missing. “Entry to the museum was discovered and taken was a solid gold replica of the 1969 Lunar Excursion Module that landed on the moon,” Russel Hunlock, Wapakoneta police chief, stated in a release. “The piece is very rare as it was presented to Neil Armstrong in Paris, France shortly after the moon landing.”

I am not hopeful the replica will be recovered. It was obviously stolen for its gold, and I would expect the thieves to quickly break it apart and melt the gold down for sale.

Japanese private rocket launch terminates early due of communication failure

9:14 am

Capitalism in space: The first launch of the first privately-built and funded Japanese suborbital rocket was terminated early today because of a communications failure.

The rocket’s developers, Interstellar Technologies, said they aborted the launch after about 80 seconds and it landed about 8 kilometers (5 miles) offshore. The aim had been to launch the rocket, called “Momo,” to an altitude of 100 kilometers (62 miles), but it only traveled about 30-40 kilometers (19-25 miles).

The Great Red Spot

9:43 am

The Great Red Spot

Cool image time! The image on the right, reduced in resolution to post here, shows one of the close-ups taken by Juno during its recent close fly-by of the Great Red Spot. What makes it different is its colors.

This image of Jupiter’s iconic Great Red Spot was created by citizen scientist Björn Jónsson using data from the JunoCam imager on NASA’s Juno spacecraft.

This true-color image offers a natural color rendition of what the Great Red Spot and surrounding areas would look like to human eyes from Juno’s position. The tumultuous atmospheric zones in and around the Great Red Spot are clearly visible.

Normally scientists enhance the colors to bring out the details. This version does not, which definitely makes it a little less dramatic but more accurate. Even so, the whirls and storms within the Spot are clearly visible.

The image was taken on July 10 from about 8,600 miles away. Note also that the entire Earth would fit inside the storm.

SpaceX now one of the world’s most valuable companies

9:37 pm

Data from a new round of investment capital fundraising says that SpaceX is now valued at $21 billion, placing it among the only six venture-backed companies worth more than $20 billion.

The article also notes that this new valuation is up from the $12 billion listed only two years ago.

Update: As noted by my readers, I have revised the post to note that this story refers not to all companies but to those that obtained their financing privately.

Video of Iranian launch today

9:22 pm

The Iranians have released video of today’s rocket launch.

I’d love a translation of what the crowd is chanting. I would also encourage the engineers in my readership to look at this and tell me if the launch looks right, and if there is any way to judge whether it is an rocket for orbital satellites or a missile. We still have no evidence the rocket successfully put anything in orbit.

Meanwhile, the Trump administration has called this launch a breach of a UN resolution forbidding Iran from developing ballistic missiles.

Cameras on next Kepler-like exoplanet space telescope out of focus

9:34 am

NASA has revealed that the cameras on the Transiting Exoplanet Survey Satellite (TESS) become slightly out of focus when they are cooled to -75 Celsius, the temperature they will experience in space.

NASA has also decided that the fuzziness is not enough to require a fix, and is proceeding with the mission as is, despite concerns expressed by scientists.

Alan Boss, an astronomer with the Carnegie Institution, brought up the issue in a summary of a meeting last week of the Astrophysics Advisory Committee, of which he is a member. “That could have some big effects on the photometry,” he said of the focus problem. “This is certainly a concern for the folks who know a lot about photometry.”

TESS will use those cameras to monitor the brightness of the nearest and brightest stars in the sky, an approach similar to that used by Kepler, a spacecraft developed originally to monitor one specific region of the sky. Both spacecraft are designed to look for minute, periodic dips in brightness of those stars as planets pass in front of, or transit, them. Chou said that since TESS is designed to conduct photometry, measuring the brightness of the stars in its field of view, “resolution is less important compared to imaging missions like Hubble.” However, astronomers are concerned that there will be some loss of sensitivity because light from the stars will be spread out onto a slightly larger area of the detector.

“The question is how much science degradation will there be in the results,” Boss said. “The TESS team thinks there will be a 10 percent cut in terms of the number of planets that they expect to be able to detect.”

It could be that NASA has decided that the cost and delay required to fix this is not worth that 10% loss of data.

Time/PBS video documentary nominated for Emmy despite factual error in title

9:25 am

Fake news: The Time/PBS video documentary A Year in Space has been nominated for an Emmy award, despite a blatant factual error in the show’s title.

I haven’t seen the documentary, and so it might a great achievement. Nonetheless, this mission only lasted 340 days, not a year, and to call it “a year in space” is not only false, but an outright lie. For a news organization to start out this wrong, in the title, and then for it to get an Emmy nomination, tells us a great deal about the standards of accuracy in television news.

Breakthrough Starshot puts smallest satellites ever into orbit

9:18 am

Breakthrough Starshot, the privately funded $100 million effort to launch a probe to the nearest star, has put into orbit the world’s smallest satellites ever.

The six prototypes, dubbed Sprites, weigh only 4 grams and contain solar panels, computers, sensors, and radios on a surface equal to that of a U.S. postage stamp. Developed by researchers at Cornell University and transported into space as secondary payloads on a rocket built by the Europe-based company OHB System AG, the nanosatellites are being tested for electronics and communication performance in orbit.

The significance here is not so much that this advances the project’s interstellar mission, but that this technology is becoming more likely for use on both commercial and planetary spacecraft.
