Europe to put instrument on Japanese rover being launched and landed on the Moon by India

9:49 am

The new colonial movement: The European Space Agency (ESA) has signed an agreement with Japan’s space agency JAXA to put a science instrument on a Japanese rover that will be launched by India to the Moon and landed there on an Indian lander.

Under the deal, ESA would provide instruments for the Japanese rover, which would be used in the exploration of the Moon’s south pole under the mission targeted for 2024. … The lunar endeavour between the Indian Space Research Organisation (ISRO) and JAXA is called the Lunar Polar Exploration Mission (LUPEX) which aims to launch an Indian lander and a Japanese rover to the Moon.

In the next three years a lot of landers and rovers are planning to land on the Moon, most built by private American companies flying NASA and private payloads, but also joined by probes being sent by Russia, China, and now this Japanese-Indian-European mission. Even if only half succeed, the exploration of the lunar surface will still be quite busy.

Europe’s deep space communications network to support India’s next two missions beyond Earth orbit

8:52 am

The new colonial movement: Based upon a 2021 agreement, the European Space Agency (ESA) today outlined how its deep space communications network of antennas will support India’s next two missions beyond Earth orbit.

ESA’s global deep-space communication antennas will provide essential support to both missions every step of the way, tracking the spacecraft, pinpointing their locations at crucial stages, transmitting commands and receiving ‘telemetry’ and valuable science data.

In June 2021, ESA and the Indian Space Research Organisation (ISRO) signed an agreement to provide technical support to each other, including tracking and communication services to upcoming Indian space missions via ESA’s ground stations.

The first missions to benefit from this new support agreement will enable India look to the Sun and the Moon with the Aditya-L1 solar observatory and Chandrayaan-3 lunar lander and rover, both due to launch in 2022 from the Satish Dhawan Space Centre in Sriharikota Range (SDSC SHAR), India.

Though scheduled for launch this year, ISRO (India’s space agency) has not yet announced firm launch dates for either.

This arrangement signals an effort by India and Europe to remain independent of the American Artemis program, which is NASA’s central program for manned missions beyond Earth orbit. To partner with NASA for such missions the Trump administration had demanded nations sign the Artemis Accords, though that requirement might have been eased by the Biden administration for deep space communications.

Regardless, this agreement gives both India and ESA flexibility for remaining outside the accords, at least for now. Neither India nor most of the partners in the ESA have signed, with France and Germany the most notable European nations remaining outside the accords.

Solar Orbiter takes closest image of Sun so far

10:18 am

Solar Orbiter's closest image of the Sun, so far
Click for full interactive image, where you can zoom in, a lot.

Cool image time! The European Space Agency (ESA) yesterday released several new images from its Solar Orbiter probe, taken when the spacecraft made its most recent closest approach of the Sun.

One of the images, taken by the Extreme Ultraviolet Imager (EUI) is the highest resolution image of the Sun’s full disc and outer atmosphere, the corona, ever taken.

Another image, taken by the Spectral Imaging of the Coronal Environment (SPICE) instrument represents the first full Sun image of its kind in 50 years, and by far the best one, taken at the Lyman-beta wavelength of ultraviolet light that is emitted by hydrogen gas.

The images were taken when Solar Orbiter was at a distance of roughly 75 million kilometres, half way between our world and its parent star. The high-resolution telescope of EUI takes pictures of such high spatial resolution that, at that close distance, a mosaic of 25 individual images is needed to cover the entire Sun. Taken one after the other, the full image was captured over a period of more than four hours because each tile takes about 10 minutes, including the time for the spacecraft to point from one segment to the next.

The photo to the right, reduced to post here, is the EUI photo.

Solar Orbiter has been in its science orbit since November, though that orbit over time will slowly be adjusted to swing the spacecraft into a higher inclination so that it can make the first close-up observations of the Sun’s polar regions. It is also working in tandem with the Parker Solar Probe, which observes the Sun from even closer distances using different instruments.

ESA makes official the split with Russia

9:32 am

At a press conference yesterday officials from the European Space Agency (ESA) officially announced that the partnership with Russia to launch its Franklin rover to Mars has ended, and the launch will not happen in ’22.

The program is not cancelled, but “suspended.” ESA is looking for alternatives to get its Rosalind Franklin rover to the Red Planet. Earth and Mars are correctly aligned for launches only every 26 months, so the next opportunities are in 2024, 2026, and 2028. Aschbacher said it is not feasible to be ready by 2024, so it will be one of the later dates.

Since Russia had been providing both the launch rocket and Mars lander, ESA cannot simply find a different rocket. It needs to come up with its own lander, or find someone else to build it. For example, one of many new private American companies building lunar landers for NASA might be able do it, though ESA would likely prefer a European company. If it did decide to go with an American company, it would certainly not hire one until it succeeds in completing successfully at least one planetary landing.

The officials also outlined ESA’s need to find new launch rockets for many other missions it had planned to launch on Russia’s Soyuz-2 rocket. That need will also be an opportunity for American rocket companies, but more significantly it could be a blessing for Arianespace’s Ariane 6 rocket. The Ariane 6 has struggled to find customers because of its high cost. The loss of Russia as a launch option will likely drive some ESA business to it.

Roscosmos’ head Dmitry Rogozin in turn announced that it will go ahead with its own Mars mission, using the lander on an Angara rocket

“True, we will lose several years, but we will replicate our landing module, make an Angara rocket for it and carry out this research mission from the newly-built Vostochny spaceport on our own. Without inviting any ‘European friends’, who prefer to keep their tails between their legs the moment they hear their American master’s angry voice,” Rogozin said on his Telegram channel.

Whether Russia will actually do this is questionable. For the last two decades Roscosmos has promised all kinds of numerous planetary missions and new rockets and new manned capsules, none of which has ever seen the light of day. To make such a thing happen now seems even more doubtful.

ESA: ExoMars launch in ’22 “very unlikely” due to Russian invasion of the Ukraine

9:05 am

In a statement yesterday condemning Russia’s invasion of the Ukraine and responding to the Russians’ decision to suspend cooperation with Arianespace in French Guiana, the European Space Agency (ESA) also admitted, almost as an aside, that the ExoMars launch in ’22 to Mars is now “very unlikely.”

That mission is a partnership with Russia, where the Russians provide the rocket and the lander that will put Europe’s Franklin rover on the surface.

For the scientists running ExoMars, this delay only adds to their frustration, as the mission has already been delayed several times, most recently from a ’20 launch because the lander parachutes — being built by ESA — were not ready.

ESA dithers, forming committee to study concept of building its own manned capsule

9:37 am

My heart be still! The European Space Agency (ESA) has decided to create a committee to study the concept of building a European manned capsule so that it will no longer be dependent on either the U.S. or Russia to get its astronauts into space.

Aschbacher said a draft mandate for the new advisory group will be presented to ESA members at a March meeting of the ESA Council, with the goal for the group to start working immediately thereafter. The committee will prepare an interim report in time for the ministerial meeting in November, with a final report by next spring.

“It is clear that this group has to be independent and comprising mostly non-space experts,” he said, “because we really would like to look at various aspects of society from an economic point of view, a historical point of view, a geopolitical point of view.” That means including people such as artists and philosophers in the group to look at various aspects of exploration beyond science and technology. [emphasis mine]

The highlighted words illustrate the empty PR nature of this committee. It will not result in any European manned spacecraft at all. Instead, it will spend more than a year talking a lot about the wonders of space, and then produce a report repeating how wonderful space is and how Europe must be there.

The result? ESA will have wasted a year and not gotten itself one iota closer to having its own manned spacecraft.

If this hollow effort was the exception to the rule for Europe, there might be hope some political pressure could get the committee reformed and actually include engineers to develop a real design. That hope is in vain, however, because this is how Europe and ESA does everything. By the time ESA produces the first designs of this capsule, probably five to six years hence, it will be so out-of-date that building it would be a joke.

In a larger sense, this absurd committee and the top management at ESA and in the European Union that proposed it illustrate the overall bankruptcy of modern civilization’s entire management class. The people running governments worldwide are generally all do-nothing idiots, who talk a lot, waste a lot of money for their own aggrandizement, impose taxes and regulations on everyone else that makes the lives of ordinary people a misery, and fail in almost every project they undertake. We need only look at their panicked, dishonest, and failed global response to the Wuhan flu in the past two years for a prime example.

The official intellectual class that is running our governments worldwide are bankrupt. They need to be fired.

ESA selects Ariane-6’s first payloads

9:05 am

The European Space Agency (ESA), ArianeGroup, and Arianespace today announced the payloads that will fly on the first launch of its new Ariane-6 rocket.

The payloads are a variety of cubesats and science experiments, none heavier than 175 pounds with a total payload weight less than one ton. These secondary payloads will either be deployed from or kept attached to a dummy mass that will simulate a large primary satellite payload.

The press release makes no mention of a launch date, as has been the pattern in the last few Ariane-6 press releases. The last release to mention a launch date was in October 2020, which then predicted a launch in the second quarter of ’22. That this date is no longer being mentioned suggests the date has been pushed back, though for how long remains a mystery.

Lockheed Martin wins NASA contract to build Mars rocket

9:11 am

Capitalism in space: NASA yesterday awarded Lockheed Martin a $194 million contract to build the Mars rocket that will lift Perseverance’s samples into orbit for return to Earth.

Set to become the first rocket fired off another planet, the MAV [Mars Ascent Vehicle] is a crucial part of a campaign to retrieve samples collected by NASA’s Perseverance rover and deliver them to Earth for advanced study. NASA’s Sample Retrieval Lander, another important part of the campaign, would carry the MAV to Mars’ surface, landing near or in Jezero Crater to gather the samples cached by Perseverance. The samples would be returned to the lander, which would serve as the launch platform for the MAV. With the sample container secured, the MAV would then launch.

Once it reaches Mars orbit, the container would be captured by an ESA (European Space Agency) Earth Return Orbiter spacecraft outfitted with NASA’s Capture, Containment, and Return System payload. The spacecraft would bring the samples to Earth safely and securely in the early- to mid-2030s.

According to this project’s webpage, the European Space Agency (ESA) is building that they call a “fetch rover” which will be deployed from the rover to get the samples and bring them back to the MAV.

There are a lot of uncertainties in this scenario. It has been decades since Lockheed Martin built rockets. ESA has not yet built an operational Mars rover. It is also unclear who will build NASA’s lander and capture/return payload. Thus, do not expect this mission to launch “as early as ’26,” as the press release says. I predict it will launch at least five, maybe ever ten years, later.

Webb telescope reaches launchpad on Ariane 5 + how to watch launch

9:14 am

The James Webb Space Telescope, stacked on top of Arianespace’s Ariane 5 rocket, has finally reached its launchpad in French Guiana after twenty years of development costing 20 times its original budget.

The launch itself is now scheduled for December 25, 2021 at 7:20 am (Eastern). It will be live streamed by both NASA (in English) and Arianespace (with options in English, French, or Spanish).

I have embedded below NASA’s feed. As always, expect NASA to pump you with lots of propaganda during its live stream.

When all is said and done, Webb has the chance to show us things about the universe we’ve never seen before. Optimized for deep space cosmology, it will provide us a window into the earliest moments of the universe’s existence. And is infrared capabilities will allow it to peer into many nearer places obscured by dust with a resolution unmatched by previous telescopes.

Keep your fingers crossed all goes as planned.

ESA delays Webb launch one day due to weather

8:41 am

The European Space Agency (ESA) announced late yesterday that, due to “adverse weather conditions” in French Guiana, it has delayed the launch of the James Webb Space Telescope on an Ariane 5 rocket one day to December 25th.

The announcement also stated that the final launch readiness review also approved the launch, though no update has yet been issued on the ground control communications problem that had caused a two day delay last week.

Meanwhile, this story and its headline encapsulates the terror I think many astronomers presently feel about this telescope:

Why Astronomers Are “Crying and Throwing Up Everywhere” Over the Upcoming Telescope Launch

The sense is one of helpless panic among astronomers who want to use Webb. They know it will do really cutting edge science, but they also know that many things can go wrong, and the history of the telescope (ten years late and 20x overbudget) will likely make replacing it impossible.

And many things can go wrong. Below is NASA’s video showing the telescope’s complex unfolding, step-by-step, after launch.

Webb launch confirmed for December 24, 2021

9:01 am

Ten years late and twenty times over budget the European Space Agency (ESA) yesterday confirmed that the launch of NASA’s infrared James Webb Space Telescope is now scheduled for December 24, 2021.

The ESA announcement is only a couple of sentences long, and does not mention if engineers had solved the intermittent ground communications issue with the telescope. Further tweets from ESA and NASA also said nothing about the communication issue.

A final readiness review is set for December 21st where a final launch decision will be made.

Scientists discover underground reservoir of hydrogen, likely ice, near Martian equator

8:58 am

Detection of underground hydrogen in Valles Marineris
Click for full image.

In what could be a very significant discovery, scientists using Europe’s Trace Gas Orbiter (TGO) have discovered a surprisingly large underground reservoir of hydrogen, likely ice, near Martian equator and inside the solar system’s largest known canyon, Valles Marineris.

The map to the right, reduced to post here, provides all the important data. From its caption:

The coloured scale at the bottom of the frame shows the amount of ‘water-equivalent hydrogen’ (WEH) by weight (wt%). As reflected on these scales, the purple contours in the centre of this figure show the most water-rich region. In the area marked with a ‘C’, up to 40% of the near-surface material appears to be composed of water (by weight). The area marked ‘C’ is about the size of the Netherlands and overlaps with the deep valleys of Candor Chaos, part of the canyon system considered promising in our hunt for water on Mars.

What the caption does not note is the latitude of this hydrogen, about 3 to 10 degrees south latitude. Assuming the hydrogen represents underground ice, this would be the first detection on Mars below 30 degrees latitude, and the very first in the equatorial regions. Data from orbit has suggested that Mars has a lot of water ice, found near the surface more and more as you move into higher latitudes above 30 degrees and making Mars much like Antarctica. Almost no ice however had until now been detected below 30 degrees latitude. As the European Space Agency’s press release noted,

Arianespace launches two Galileo GPS-type satellites

8:14 pm

Capitalism in space: Using a Russian Soyuz-2 rocket, Arianespace successfully launched two Galileo GPS-type satellites from its spaceport in French Guiana tonight.

The leaders in the 2021 launch race:

45 China
27 SpaceX
20 Russia
6 Europe (Arianespace)

China still leads the U.S. 45 to 42 in the national rankings. This launch tonight was 116th successful launch in 2021, which is the most launches completed in a year since 1988. Based on the number of planned launched over the next three weeks, there is an outside chance that the global total will top 127, making this the second most active year ever in the history of space. Even if the numbers end up in the mid-120s, 2021 will be among the top eight years ever.

And I expect next year to easily top this year.

Mars Express successfully relays data from Zhurong to Earth

10:21 am

The European Space Agency’s Mars Express orbiter has successfully been used to relay data from China’s Zhurong Mars rover to Earth and then to China.

In November, ESA’s Mars Express and CNSA’s Zhurong teams carried out a series of experimental communication tests in which Mars Express used this ‘in the blind’ mode to listen for signals sent to it by the Zhurong Rover.

The experiments culminated in a successful test on 20 November. “Mars Express successfully received the signals sent by the rover, and our colleagues in the Zhurong team confirmed that all the data arrived on Earth in very good quality.” says ESA’s Gerhard Billig.

Apparently, normal communications would first involve “handshake” communications between the two, but that requires communications frequencies Zhurong does not use. Mars Express instead had to grab the data on the blind. The test was a success, which means the ESA will likely act as another communications relay for Zhurong, in addition to China’s Tianwen-1 orbiter, as the rover’s mission on Mars continues.

Engineers: Webb undamaged by “incident”, ready for December 22nd launch

9:46 am

Arianespace engineers have confirmed after testing that the James Webb Space Telescope was undamaged by “incident” that occurred during stacking, and have okayed the resumption of the telescope’s preparation for launch.

On Wednesday, Nov. 24, engineering teams completed these tests, and a NASA-led anomaly review board concluded no observatory components were damaged in the incident. A “consent to fuel” review was held, and NASA gave approval to begin fueling the observatory. Fueling operations will begin Thursday, Nov. 25, and will take about 10 days.

The launch is now set for December 22nd.

Europe’s Solar Orbiter to make last flyby of Earth

8:51 am

Solar Orbiter, the European Space Agency’s (ESA) probe to work in tandem with NASA Parker Solar Probe in studying the inner regions surrounding the Sun, will make last flyby of Earth on November 27, 2021, thus putting it into its planned science orbit.

While the press release gives a good overview of the mission, it focuses on the risk during that fly-by of the spacecraft hitting something during its close approach.

Solar Orbiter’s Earth flyby takes place on 27 November. At 04:30 GMT (05:30 CET) on that day, the spacecraft will be at its closest approach, just 460 km above North Africa and the Canary Islands. This is almost as close as the orbit of the International Space Station.

The manoeuvre is essential to decrease the energy of the spacecraft and line it up for its next close pass of the Sun but it comes with a risk. The spacecraft must pass through two orbital regions, each of which is populated with space debris.

The first is the geostationary ring of satellites at 36 000 km, and the second is the collection of low Earth orbits at around 400 km. As a result, there is a small risk of a collision. Solar Orbiter’s operations team are monitoring the situation very closely and will alter the spacecraft’s trajectory if it appears to be in any danger.

While there is a risk, it seems to me that ESA is taking advantage of the recent news outburst in connection with the Russian anti-sat test and the space junk it created to sell this mission. The risk of impact during this fly-by is very low, especially in the geostationary ring.

Zhurong’s continuing travels on Mars

10:26 am

Zhurong overview map
Click for original map.

This past week the Chinese press released a new but limited update on the status of both its Mars orbiter Tianwen-1 and its Mars rover Zhurong.

The map to the right uses as its background a high resolution picture from Mars Reconnaissance Orbiter. I have superimposed Zhurong’s route in green. You can get an idea of how far the rover has traveled since resuming communications with Earth in late October by comparing this map with the one I posted then. After stopping at a small sand dune (the crescent-shaped white features), it curved around to head to the southeast towards a rough area and a trough that is thought to be filled with sediment.

Meanwhile, the orbiter has shifted its orbit, changing from one dedicated mainly as providing a communications relay between Zhurong and Earth to one that now allows it to begin a two-year photographic survey of Mars.

To supplement the resulting gaps in communications for Zhurong, China and the European Space Agency (ESA) have made their first test using ESA’s Mars Express satellite as a relay satellite. Both hope to know soon whether it worked.

In either case, Zhurong’s travels will likely be slowed somewhat due to the reduction in communications access.

Italy switches from Arianespace to SpaceX for launch contract

9:05 am

Capitalism in space: Because of the two recent launch failures of Arianespace’s Vega rocket (built mostly in Italy), the Italian space agency (ASI) has decided to take the launch of an Earth observation satellite from Arianespace and award the launch contract instead to SpaceX.

The article at the link describes in detail the history and politics that make this decision significant. Essentially, because Arianespace in the past decade has failed to meet the challenge of SpaceX, so that its launches continue to be more expensive, this government-subsidized business has tried to force nations in the European Space Agency (ESA) to use Arianespace rockets via political agreements.

With this decision Italy is defying that pressure, which in turn is going to increase the pressure on Arianespace to finally step up its game, or die from lack of business. For example, when the ESA agreed to have Arianespace build its next generation rocket, the Ariane 6, it failed to require it to be reuseable. The Ariane 6 rocket was therefore designed as an expendable rocket, which meant that right from the start it could not compete with SpaceX’s Falcon 9. It has therefore failed to win launch contracts.

Expect the Ariane 6 to continue to fade as the years pass, simply because the bureaucrats in ESA and Arianespace refused to take their competition seriously.

BepiColombo about to make first of six Mercury flybys

11:16 am

The European/Japanese BepiColombo probe will make its first of six fly-bys of Mercury on October 1, 2021, as it steadily adjusts its flight path to enter orbit around the planet in 2025.

The mission is made up of two Mercury orbiters, Europe’s Mercury Planetary Orbiter and Japan’s Mio orbiter.

During the flybys it is not possible to take high-resolution imagery with the main science camera because it is shielded by the transfer module while the spacecraft is in cruise configuration. However, two of BepiColombo’s three monitoring cameras (MCAMs) will be taking photos from about five minutes after the time of close approach and up to four hours later. Because BepiColombo is arriving on the planet’s nightside, conditions are not ideal to take images directly at the closest approach, thus the closest image will be captured from a distance of about 1000 km.

The first image to be downlinked will be from about 30 minutes after closest approach, and is expected to be available for public release at around 08:00 CEST on Saturday morning. The close approach and subsequent images will be downlinked one by one during Saturday morning.

The cameras provide black-and-white snapshots in 1024 x 1024 pixel resolution, and are positioned on the Mercury Transfer Module such that they also capture the spacecraft’s solar arrays and antennas. As the spacecraft changes its orientation during the flyby, Mercury will be seen passing behind the spacecraft structural elements.

These will be the first close-up pictures of Mercury since the Messenger orbiter mission ended in 2015.
