Dust and clouds in the Martian atmosphere, as seen by UAE’s Al-Amal orbiter

11:18 am

Two new science papers have just been released detailing results from the Al-Amal (Hope) Mars orbiter that was designed and built by American universities for the United Arab Emirates (UAE).

Both papers used data obtained from the orbiter’s infrared spectrometer, dubbed the Emirates Mars Infrared Spectrometer (EMIRS).

Daily cloud cover changes on Mars

First, the instrument tracked the daily changes in the planet’s cloud cover.

A prominent region of clouds that is commonly observed near the equator during Mars’ cold season—known as the aphelion cloud belt—was observed to reach a minimum near midday, with more clouds typically observed in both the morning and afternoon. Distinct differences were found in clouds observed near volcanoes, which tended to reach a minimum before local noon and increase throughout the afternoon.

The figure to the right shows this. In the morning and afternoon (LTST’s 7 and 17), there is a high concentration of clouds in the equatorial region above the Tharsis Bulge where the highest Martian volcanoes are located. During the middle of the day (LTSTs 11 and 13) this cloud cover largely dissipates, with a corresponding increase in cloud cover in Hellas Basin, in the southern hemisphere.

The second paper took a more general look at the data, including the change in temperature depending on elevation as well as dust and water content during the Martian northern spring and summer. From the abstract:

Al-Amal detects Martian aurora

10:11 am

Aurora on Mars

The United Arab Emirates Al-Amal Mars orbiter has detected evidence of a Martian aurora that would be visible at night for short periods.

The ultraviolet images to the right have been reduced slightly to post here.

These three images of atomic oxygen emission at a wavelength of 103.4 nm from the planet Mars were obtained by the Emirates Mars Ultraviolet Spectrometer instrument on 22 April, 23 April, and 06 May 2021 respectively. The full set of data collected during these observations include far and extreme ultraviolet auroral emissions which have never been imaged before at Mars. The beacons of light that stand out against the dark nightside disk are highly structured discrete aurora, which traces out where energetic particles excite the atmosphere after being funneled down by a patchy network of crustal magnetic fields that originate from minerals on the surface of Mars.

Though Mars does not have a magnetic field, it is believed that sections of the planet’s crust are magnetized, and under the right conditions can guide the charged particles from the Sun’s solar wind to the night side to hit the atmosphere where they break up and produce the aurora. Because there is no magnetic field however the particles are not guided by the field lines to the poles, but to different spots at all latitudes, depending on circumstances.

The atomic hydrogen in Mars’ atmosphere

Atomic hydrogen in Mars' atmosphere, as seen by Al-Amal

The two photos to the right, cropped and reduced to post here, were taken by the ultraviolet spectrometer on the UAE Mars orbiter Al-Amal (“Hope” in English) on April 24 and April 25.

During the 10 hours 34 minutes between the images, the Hope probe moved from being over the planet near noon and viewing the entire dayside (top) to being over the planet at dusk and seeing both the day and night side (bottom). These images will be used to reconstruct the 3D distribution of hydrogen and learn more about its production through the process of splitting water molecules by sunlight and its eventual escape to space.

This data will eventually allow scientists to more precisely measure the total water loss to space that Mars’ experiences annually, which will also allow them to determine approximately how much water the planet has lost over the eons.

Al-Amal reaches science orbit

1:22 pm

Cerberus Fossae, as seen by Al-Amal

Elysium Mons and Cereberus Fossae

The new colonial movement: The United Arab Emirates (UAE) Al-Amal (Hope) Mars Orbiter has now reached its science orbit, and will begin its two years of observations (one full Martian year) of the Martian atmosphere on April 14th.

The photo to the right, cropped to post here, is part of a much larger image covering a good portion of the 600-mile-long fissures dubbed Cerberus Fossae and located Elysium Planitia, the vast lava plains located between the giant volcanoes Elysium and Olympus Mons, where most of the Martian quakes have so-far been detected by InSight. The context map below provides a wider context (the red boxes indicating high resolution Mars Reconnaissance Orbiter images). I think the area covered by this section of Al-Amal’s picture is near the western end of Cerberus Fossae.

The image was posted today in the image gallery for Al-Amal. Unfortunately there is no separate webpage for this particular post, so that link will take a long time to load, as apparently all the images there are large, not thumbnails. From their text:

On 15 March 2021, the Emirates eXploration Imager (EXI) captured a monochromatic image of the Cerberus Fossae, a fracture system that stretches for more than 1,000 km across the Martian surface, with a spatial scale of approximately 180 meters/pixel. The Emirates Mars Mission transitioned from the capture orbit to its science orbit with the successful completion of a 510-second burn of its thrusters. The Hope Probe is now in its final orbit of Mars and ready for its two-year science data gathering – the core aim of the mission. The science phase will commence on 14 April 2021.

The goal of Al-Amal is to study the atmosphere. This camera will provide wide shots, mostly for the purpose of observing the coming and going of cloud features. Nonetheless, this is a nice wide view of Mars.

First results from UAE’s Al-Amal/Hope Mars orbiter

10:36 am

First data from Al-Amal
Click for full image.

The first science results from the United Arab Emirates Al-Amal Mars orbiter (“Hope” in English) have been released by the American universities operating one instrument.

The image to the right shows that data. The right globes show the areas of actual temperature data for both the Martian surface and atmosphere, with the left globes extrapolating that data across the entire planet.

The purple-green-blue hues show that the measurements were taken of the Martian nightside, although dawn on the planet can be seen on the right-hand side of the surface temperature image, as depicted by the red hues. Features such as Arabia Terra, which has cold nighttime temperatures, can be observed in the upper left portion of the surface temperature data, depicted by the blue and purple hues.

“EMIRS [the infrared spectrometer] is going to acquire about 60 more images like this per week once we transition into the primary science phase of the Emirates Mars Mission,” said EMIRS Instrument Scientist Christopher Edwards, who is an assistant professor and planetary scientist at [Northern Arizona University]. “We’ll use these images and sophisticated computer programs to build up a complete global, daily understanding of the Martian atmospheric components, like dust, water ice, water vapor and atmospheric temperature.” [emphasis mine]

The highlighted words above illustrate the true nature of this U.S./UAE joint mission. Right now the spacecraft is being operated by Emirate engineers in the UAE, but the spacecraft and its instruments were really built by U.S. universities, paid for by the UAE. As such, those American universities remain in charge of running those instruments, though UAE students are also being used to do that work as part of their education.

None of this is to denigrate the effort by the UAE. It used its financial resources to buy the expertise of American universities and companies to build this Mars orbiter, but did so with the express requirement that those American universities and companies also educate and train its people in such work.

That deal however once again illustrates the value of private enterprise and freedom. The UAE wanted to teach its people how to fly a planetary space mission. American universities had the knowledge to do it. The former then bought the skills from the latter, while the latter then got a science mission for free.

A match made in heaven with both benefiting marvelously.

UAE releases first Al-Amal image of Mars

9:45 am

Al-Amal's first Mars image
Click for full image.

The new colonial movement: The leader of the United Arab Emirates (UAE) yesterday released on his twitter feed the first photo of Mars that was beamed back from its Al-Amal (“hope” in English) orbiter, taken shortly after achieving orbit.

That photo is to the right, cropped and reduced to post here. From the article at the link:

[The photo] was captured by Hope’s EXI instrument from an altitude of 24,700 km (15,350 miles) above the Martian surface at 20:36 GMT on Wednesday – so, one day after arriving at the Red Planet.

The north pole of Mars is in the upper left of the image. At centre, just emerging into the early morning sunlight, is Olympus Mons, the largest volcano in the Solar System. Look right on the boundary between night and day, the so-called terminator.

The three shield volcanoes in a line are Ascraeus Mons, Pavonis Mons, and Arsia Mons. Look east, to the limb of the planet, and you can see the mighty canyon system, Valles Marineris. It’s part covered by cloud.

Right now the spacecraft’s orbit is very eccentric, ranging from 600 to 30,000 miles above the Martian surface. After several orbital trims, Al-Amal will end up in an orbit about 14,000 by about 27,000 miles, with an inclination of about 25 degrees. From that high orbit it will then focus on studying the Martian atmosphere.

Thus, future images will likely be similar to this, global and mostly aimed at tracking visible phenomenon in the atmosphere (dust storms and clouds).

UAE’s Hope or Al-Amal Mars Orbiter orbital insertion

8:31 am

UPDATE: The probe has apparently achieved orbit.

The new colonial movement: The United Arab Emirates’ (UAE) Mars orbiter, Hope, or Al-Amal in Arabic, is about to insert itself into orbit around the red planet, with that insertion to be confirmed by 11:08 (Eastern).

If you want to watch, I have embedded the live stream below the fold. A warning: The insertion is a relatively interesting event to watch, as the orbiter works autonomously and the signal confirming it happened arrives after the event. Most of the stream is propaganda for the UAE.

The new invasion of Mars begins next week!

10:13 am

In the next two weeks three spacecraft will arrive at Mars, including two orbiters and two rovers. This post is simply a heads up so that my readers will know what to expect and when to expect it.

First, we have the arrival in Mars orbit of the United Arab Emirates’ (UAE) Hope orbiter on February 9th at 10:30 am (Eastern). The spacecraft was built in a partnership with U.S. universities and the UAE. Once in orbit it will focus on studying the Martian atmosphere.

Next will arrive China’s Tianwen-1 orbiter on February 10th. The exact time it will do its engine burn to enter orbit has not been announced, as far as I can tell. Once in orbit it will begin a four month reconnaissance of the landing site for its presently unnamed rover, which will descend to the surface in May.

Finally, on February 18th at 12:55 am (Pacific) the American rover Perseverance will land in Jezero Crater on Mars. Essentially an upgraded copy of the Curiosity rover, it will land in the same way, lowered by cables from its re-entry sky crane rocket above it. It will then spend years studying the geology of Mars, while also storing samples that a later mission can recover and return to Earth.

All in all February is going to be an exciting month for the exploration of Mars. Stay tuned for some cool stuff!

UAE’S Hope Mars Orbiter images Mars

9:09 am

The United Arab Emirates’ (UAE) Hope Mars Orbiter has successfully imaged Mars for the first time using its star tracker camera, proving both that the spacecraft is on course and that its pointing capabilities are working as well .

“The Hope probe is officially 100 million km [60 million miles] into its journey to the Red Planet,” Mohammed bin Rashid Al Maktoum, prime minister of the UAE, wrote on Twitter on Monday (Aug. 24). “Mars, as demonstrated in the image captured by the probe’s star tracker, is ahead of us, leaving Saturn and Jupiter behind. The Hope probe is expected to arrive to Mars in February 2021.”

The star tracker is designed to keep Hope on course, telling the spacecraft precisely where it is. In addition, the probe carries a more traditional camera for use once it arrives at Mars and begins its science work.

Arrival in Mars orbit will take place in February ’21.

Hope completes first course correction on trip to Mars

3:24 pm

The new colonial movement: The United Arab Emirates’ (UAE) Mars Hope orbiter has successfully completed its first course correction on its journey to Mars.

The success of this maneuver is a big deal, as it appears it was controlled from the UAE’s control center by its engineers. Up to now this project has mostly been a joint U.S/UAE project, launched by Japan, with U.S. universities doing the heavy lifting while training UAE personnel. Now the UAE engineers are in charge, and so they have to get it right.

They have another half dozen course corrections scheduled before arrival in February 2021, when the spacecraft will have its big maneuver, entering Martian orbit.

Why the UAE’s Hope Mars Orbiter is really a US mission for UAE’s students

11:10 am

Today there were many many news stories touting the successful launch of the United Arab Emirates’ (UAE) first interplanetary probe, Hope, (al-Amal in Arabic), successfully launched yesterday from Japan. This story at collectSpace is typical, describing the mission in detail and noting its overall goals not only to study the Martian atmosphere but to inspire the young people in the UAE to pursue futures in the fields of science and engineering.

What most of these reports gloss over is how little of Hope was really built by the UAE. The UAE paid the bills, but during design and construction almost everything was done by American universities as part of their education programs, though arranged so that it was UAE’s students and engineers who were getting the education.

UAE’s Hope Mars Orbiter successfully launched

9:12 pm

The new colonial movement: The United Arab Emirates first interplanetary probe, its Hope Mars Orbiter, was successfully launched by a Mitsubishi H-2A rocket today from Japan, and is now on its way to Mars.

It will arrive in February 2021, when it will attempt to inject itself into orbit, where it will then be used to study the Martian weather.

The leaders in the 2020 launch race:

16 China
10 SpaceX
7 Russia
3 ULA
3 Japan

The U.S. still leads China in the national rankings, 17 to 16.

Launch update on Mars missions

9:24 am

The launch status of the three missions to Mars:

First, the launch of UAE’s Hope orbiter by Mitsubishi’s H-2A rocket has been pushed back to July 20th due to bad weather. Their launch window extends to August 3rd, so they still have two weeks before it closes.

Second, China has rolled to the launchpad the Long March 5 rocket, with the Tienwen-1 orbiter/lander/rover. Though they have only said that the launch will occur between July 20th and July 25th, based on past operations, they usually launch six days after roll-out, putting the launch date as July 23.

China has also provided some clarity as to Tienwen-1’s landing site on Mars. According to this Nature Astronomy paper [pdf], published on July 13th, their primary landing site is in the northern lowland plains of Utopia Planitia. The Tienwen-1 science team has also considered [pdf] the northern lowland plains in Chryse Planitia, on the other side of Mars.

Since they will spend two to three months in Mars orbit before sending the lander and rover to the surface, it could very well be that they won’t make a final decision until they get into orbit.

Finally, on July 7th Perseverance was mounted on top of its Atlas-5 rocket for its July 30th launch. Its launch window closes on August 15.

Launch delays for SpaceX and UAE

12:21 am

The launches planned for tomorrow by SpaceX and Japan’s space agency JAXA have both been postponed, for different reasons.

The SpaceX launch of a South Korean military satellite was postponed in order to swap out equipment in the Falcon’s upper stage. No new launch date has yet been announced.

The JAXA launch, using Mitsubishi’s H-2A rocket, was to launch the United Arab Emirates’ Mars orbiter Hope. It was postponed due to bad weather. Their next launch window is July 16, but they have not yet announced a new launch date. Like Perseverance, they must launch this summer or they will have to wait two years for the next launch window to Mars to reopen.

Launch date for UAE’s Hope Mars orbiter set

9:27 am

The new colonial movement: Japan and the United Arab Emirates (UAE) have set the launch date for UAE’s Hope Mars orbiter, now scheduled for July 15 with a launch window that closes on August 13.

If all goes well it will enter Mars orbit in February 2021.

The probe is a UAE project in name only. Much of it was built in the U.S. by U.S. companies, working with UAE engineers and scientists. It is also being launched by Japan.

Regardless, the training and knowledge obtained by those UAE engineers and scientists is the real point of the mission. The UAE wants to diversify its economy away from oil, and it is trying to use the excitement of space exploration to do it. It hopes these engineers and scientists will use what they learned to come up with new projects that in the future will be built entirely in the UAE.

UAE’s Mars probe arrives in Japan for launch in July

9:31 am

The new colonial movement: The United Arab Emirates’ (UAE) Mars orbiter, dubbed Hope, has arrived at its launch site in Japan in preparation for its July launch on a Mitsubishi H-2A rocket.

Previously I had thought the probe had been built in the UAE with help from engineers from India, but that was not the case. Instead, the probe was mostly built by Americans, in America.

Carrying three science instruments, the Hope mission will measure conditions in the Martian atmosphere from a unique semi-synchronous orbit high above the Red Planet. The mission is the first from the Arab world to travel to another planet.

About the size of Mini Cooper, the spacecraft was assembled at LASP’s facilities in Colorado [Laboratory for Atmospheric and Space Physics], with the help of Emirati engineers and scientists. The probe was delivered to Dubai in February for additional testing, and then was supposed to be transported to Japan in early May.

But the coronavirus pandemic forced officials to shuffle the schedule, and mission managers decided to send the probe to Japan early. [emphasis mine]

In other words, this probe might be financed by the UAE, and it might have UAE engineers and scientists involved, but essentially the UAE paid LASP to build it for them.

I am not criticizing the UAE for this effort, but to call it an Arab mission is somewhat dishonest. This is a joint American-UAE probe. If it results in producing qualified engineers in the UAE capability of building their own future planetary probe, fine. They are not doing it now, however.

UAE’s space agency declares its Mars probe almost ready for launch

9:08 am

The new colonial movement: The space agency of the United Arab Emirates (UAE) today announced that its 2020 Mars orbiter, dubbed Hope, is now 85% complete and on track for making its launch window.

The Probe has already entered an intensive testing phase to ensure its readiness before the launch date, with less than 500 days are remaining for the launch. It is planned to reach Mars by 2021, coinciding with the 50th anniversary of the founding of the UAE.

Several aspects related to the design, assembly of the structure, cameras and control have been verified. So far, the Probe’s systems and components, as well as its ability to communicate with the ground station have been checked by the team. The Probe has succeeded in all the tests it has been subject to so far, ahead of the five environmental tests to be conducted on the probe from June to December 2019.

While this is likely true, we must remain a bit skeptical. Though the link goes to a Reuters Arab news source, the story appears to be entirely a copy of the press release. I know this because five different Arabian news sources used the exact same language in their stories, apparently all copying from the same release.

Thus, we don’t have any independent press in the UAE looking at what is going on here. This could be true, but who knows?

UAE’s Mars mission on schedule for 2020 launch

8:59 am

The new colonial movement: According to one of the chief engineers for the United Arab Emirates’ (UAE) unmanned mission to Mars, dubbed Hope, the spacecraft is on schedule for its 2020 launch by a Japanese rocket.

If all goes right, Hope will go into Martian orbit in 2021.

The quotes in the article from that chief engineer reveal somewhat the overall shallowness of UAE’s space effort at this point.

Omar Hussain, Lead Mission Design and Navigation Engineer for the Emirates Mars Mission, speaking at the Science Event 2019 held at Mohammed Bin Rashid Space Centre in Dubai, said the team have had to overcome a number of challenges along the way.

“It is too early to talk about a specific date just yet but everything is on track and there have been no delays,” said the 29-year-old Emirati. “Speaking for myself, it has been challenging because I had to switch from planning for Earth-based projects to interplanetary missions.

“It took a lot of education to get to that point as I had never done a mission that goes beyond the Earth’s lower orbits. I had to study how I would get the spacecraft from Earth to Mars.”

The goal with their space program is to help diversify UAE’s economy. It might eventually do this, but for now, they I think are very dependent on the help they are getting from others. Japan is providing the rocket, and India the engineering expertise for the spacecraft.

Life as it should be

8:10 pm

An evening pause: Tomorrow will be the 41st anniversary of the Apollo 11 landing on the Moon. So, let’s start the week with a clip from the 1972 film version of Man of La Mancha to show why some impossible dreams are certainly possible. In this short scene, Peter O’Toole, as Cervantes, explains why he does not like to look at life, “as it is.”
