Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on November 1, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a wonderful example of a glacier-filled canyon on Mars, the ice apparently flowing both along and around mesas as it carves its way downhill.

I think the downhill grade here is to the north, but this could be wrong for the two side canyons on the main canyon’s north side.

Not only is the material in the canyon likely ice, covered with a protective layer of trapped dust and ash that makes the glacier surface look so smooth, the mesa tops are likely impregnated with ice as well. The mesas however have little dust, so the plateaus have a mottled stippled look likely caused by sublimation of that underground ice.

The location of these canyons explains the presence of ice.

Today’s blacklisted Americans: Religious pro-lifers prevented from viewing Bill of Rights because National Archives forbids free speech

12:35 pm

The evil hat that Air & Space banned
An example of the evil pro-life clothing
banned by the National Archives

They’re coming for you next: Students and parents and others who had just attended the January 20, 2023 March for Life event in Washington were told by numerous National Archives security officials that day that they must remove or cover any pro-life shirts, jackets, hats, or buttons or they would be ejected from the museum.

From the lawsuit [pdf] filed by three of those pro-life individuals:

Plaintiff L.R., her mother, and her fellow classmates [about 35 people] were ushered through security and into the first group of visitors to enter the Rotunda where the Constitution and Bill of Rights are on exhibit.

…Approximately five minutes later, Plaintiff L.R. and her fellow classmates were suddenly approached by Defendant John Doe 1 who instructed Plaintiff L.R. and her classmates to remove all pro-life attire. John Doe 1 specifically instructed Plaintiff L.R. that she could not be wearing anything pro-life and that she must cover her shirt and not unzip it until she had left the National Archives. John Doe 1 also instructed Plaintiff L.R. and her other classmates to remove their pro-life buttons. John Doe 1 made other classmates standing near Plaintiff L.R. remove their pro-life hats. One such hat contained the inscription, “LIFE always WINS.” Another hat contained the inscription, “ProLife.” Plaintiff L.R. witnessed another guard participate in these instructions to her classmates and at no time did any of the other guards in the Rotunda intercede and provide contrary instruction.

Winter finally ends for Ingenuity

9:47 am

According to a detailed update today by Travis Brown, Chief Engineer of the Mars helicopter Ingenuity, the helicopter has now finally exited its difficult winter conditions that began in May 2022 and only ended at the end of January 2023.

One month to the day after the Dec. 24 flight attempt, Ingenuity did something it hadn’t done during the previous 260 sols – it slept “warmly” through the entire night. Data leading up to this event had suggested that such a survival was possible, but 8 long months of winter had tempered the team’s optimism. When Ingenuity’s team reviewed the downlinked data, they found that not only had it started living through the night, but had actually begun to bank power in its batteries. We’ve now seen end-of-sol states of charge in our batteries of more than 90% — an unbelievable number just days earlier. All the above means our sleepy friend has finally awoken from its long winter malaise, just in time to race up the Jezero Crater Delta and provide valuable advanced imaging for Perseverance.

Brown describes in detail their struggle for the past eight months to keep Ingenuity alive. That information is going to be crucial in designing future Mars helicopters, including the ones that will return to Jezero Crater sometime in the next decade to grab the core samples Perseverance has deposited for pick up and return to Earth.

Canadian rocket startup dies because of opposition to noise produced by its engine tests

9:39 am

Though there were likely other issues, according the CEO of the now defunct rocket startup SpaceRyde the company died when the local government blocked engine tests on a piece of rural land it had purchased because of local protests.

The Trent Hills municipality of Ontario asked SpaceRyde to stop engine tests from a lot in the region Oct. 7 after their noise brought attention to how an industrial application was operating on rurally zoned land. When SpaceRyde bought the land, “the understanding at the time was it would be a temporary operation that focused on supporting the business of testing balloon technology to deliver satellites into orbit,” Trent Hills mayor Bob Crate said during a Sept. 13 council meeting.

A petition started last year to stop SpaceRyde rocket engine tests it says can be “heard for many miles” has received more than 800 signatures.

We are clearly entering a dark age when the general public cannot tolerate the noise produced during short static fire engine tests lasting generally no more than one or two minutes.

China aiming to complete 80 launches in 2023

9:30 am

According to this Space.com article, China’s many pseudo-company rocket startups are hoping to complete a total of approximately 19 to 21 launches in 2023, which when combined with the 60-plus launches the government hopes to complete, will give China a total of approximately 80 launches in 2023, a new record.

The article provides a good review of all of the pseudo-companies hoping to launch in the next few years. This list includes the following:

  • Galactic Energy: 8 to 10 launches in ’23 with its Ceres-1 solid fueled rocket
  • Space Pioneer: The first launch of its liquid-fueled Tainlong-2 rocket
  • Exspace: 7 launches with its Kuaizhou-1A and larger Kuaizhou-11, both solid-fueled
  • Landspace: A second launch attempt of its liquid-fueled Zhuque-2 rocket after a launch failure in ’22
  • Orienspace: The first launch of its Gravity-1 solid fueled rocket
  • Rocket Pi: The first launch of its Darwin-1 liquid fueled rocket
  • Ispace: Unknown after three consecutive launch failures of its Hyperbola-1 solid-fueled rocket

The article also adds launches from two government “private” spinoffs, CAS Space, planning 3 launches of its PR-1solid fueled rocket, and China Rocket, planning at least one launch of its Jielong-3 solid fueled rocket. Though both are touted as private, they are both really separate divisions created by China’s space agency CASC, with their launch counts likely included in the government’s hope-for 60 launches.

The pseudo private companies are somewhat more independent as they were founded by private individuals. All appear to have obtained private Chinese capital — in addition to government funding — to fund their development. All however are also entirely supervised in all actions by the government. None could build anything without government approval, and all are depending on government rocket technology that can be withdrawn at any time. These pseudo companies don’t really own their rockets. Furthermore, while they are able to sell their products to other private entities, their market appears almost entirely confined to China.

Intuitive Machines completes merger with SPAC as it goes public

9:02 am

Intuitive Machines, one of a handful of American companies building lunar landers for NASA and others, has completed its merger with a special purpose acquisition company (SPAC), thus becoming a publicly traded stock but raising less money than expected in the process.

Intuitive Machines said Feb. 13 it had closed its merger with Inflection Point Acquisition Corp., a SPAC that trades on the Nasdaq. The merged company, retaining the Intuitive Machines name, will trade on the Nasdaq starting Feb. 14 under the ticker symbol LUNR.

The companies announced the merger in September 2022, long after the mania surrounding SPACs has cooled both in the space industry and the overall market. Inflection Point had $301 million of cash in trust, and the companies said they had arranged an additional $55 million in investment from the SPAC’s sponsors and a founder of Intuitive Machines, along with $50 million CF Principal Investments LLC, an affiliate of Cantor Fitzgerald & Company. In an investor presentation linked to the merger announcement, the companies anticipated having more than $330 million in cash after transaction expenses.

However, in the Feb. 13 announcement that the merger had closed, the companies announced only $55 million of “committed capital from an affiliate of its sponsor and company founders.”

It appears that many investors in Inflection Point itself (30% of whom had voted against this merger) had pulled their money from the fund, depleting the $301 million that was originally promised. In addition, yesterday’s announcement made no mention of the $50 million that CF had also committed.

Essentially, the company’s future hinges on the success of its first lunar mission, presently scheduled for June. Should it succeed, the company should be able to replace from other investors the funds that it failed to raise in this merger. Should it fail, it is very possible it will go belly up, as it is likely it will find it difficult if not impossible to find further investment capital.

There is of course the possibility that NASA will keep the company afloat with additional funding, but if so it might be a case of throwing good money after bad, something our government is very good at doing.

  • Blue Origin says it has made both solar cells and electricity transmission wires from simulated lunar soil

    • The article claims this is a major breakthrough, but I am sincerely underwhelmed. Though eventually such technology might be important for lunar colonists, right now it makes no sense to spend private capital on it. For at least the next two decades, power on the Moon is going to from solar panels shipped there. Other companies such as Astrobotics are developing cheap and easy-to-ship-and-install panels for those first missions, and they, not Blue Origin, are going to reap the profits.

 

 

  • Pseudo Chinese rocket startup Space Pioneer gearing up for first launch of Tianlong-2 rocket by end of March

    • If successful, it would be the first liquid fueled rocket by a Chinese pseudo company to reach orbit. Others have tried and failed.

Cracked ash-filled Martian terrain

Cracked ash-filled fissures on Mars
Click for original image.

Cool image time! The photo to the right, cropped, reduced, and sharpened to post here, was taken on September 26, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The science team labeled this “Possible Pit,” but other than a small dark stain on the rim of a crater north of the section cropped to the right, I could find nothing that even closely resembled a pit. More likely the scientists were referring to the large circular depression in the top center of this picture. It does not at first glance look like a crater, as it has no obvious rim. In fact, almost none of the circular depressions in this image look like craters, as almost none have uplifted rims.

However, it is not clear what caused these dust-filled fractures as well as the image’s many circular depressions. The location, as indicated by the overview map below, does not really help.

First picture of hole that occurred on Soyuz in December

Hole in First picture of hole that occurred on Soyuz in December

Russia has now released an image taken using the robot arm on ISS of the leak that occurred on its Soyuz capsule docked to ISS in December.

The picture to the right, cropped and reduced to post here, is that image. This is not the coolant leak hole on the Progress freighter on February 11th, this past weekend. As of now no image of that hole has ever been released.

No interpretation of this hole and the stain around it has as yet been released. However, Russia has now postponed the launch of the next Soyuz capsule from February 19th until early March in order “to give investigators time to rule out similar issues in the upcoming mission.” This Soyuz was to launch unmanned to replace the Soyuz that leaked in December and provide the astronauts that launched on that leaking Soyuz a safe lifeboat that they could come home on.

Meanwhile, all communications with ISS have now been shifted to the private channels, so the public cannot hear them.

All these actions strongly suggest that both the Russians and Americans are now seriously considering the possibility of sabotage or damage to the coolant systems on all Russian spacecraft, before they leave the factory and are launched.

ISS as of February 11, 2023

To clarify the situation, the image to the right shows all the spacecraft presently docked to ISS. Progress 82 is the spacecraft that experienced a leak in its coolant system on February 11th. Soyuz-MS22 experienced a leak in its coolant system in December. At the moment the only safe vehicle for returning the seven astronauts on ISS is Crew-5 Dragon, SpaceX’s Endurance spacecraft. Should a major catastrophe occur requiring an immediate evacuation of the station, the plan right now is for five astronauts to come home on Endurance, and two Russians to come home on the damaged Soyuz. (The thinking is that having only two men on board will prevent too much of a temperature rise during the return to Earth because of the lack of its coolant system.)

With the delay in the launch of the replacement Soyuz lifeboat, this emergency plan will be in place for at least three weeks longer.

A real blacklist designed to choke ad profits from conservative and legitimate news organizations

11:34 am

Blacklisted conservative news outlets
Conservative news outlets blacklisted by Microsoft’s Xandr,
based on advice from GDI

They’re coming for you next: Using American federal funds, a British “disinformation” group called the Global Disinformation Index (GDI) has created a real blacklist of valid and longstanding conservative news organizations and fed that list to internet ad companies to encourage them to cut ad revenue from those news organizations.

A sampling of the blacklisted news companies that have actually been punished financially by this effort is shown to the right

Of the ad companies, a Microsoft company named Xander appears to be the most enthusiastic about using GDI’s blacklist to choke ad sales to conservatives sites.

GDI’s “dynamic exclusion list” includes at least 2,000 domains, many of which are “foreign state-sponsored news and opinion sites, forums that traffic in disinformation, and explicitly sanctioned websites,” according to a second source close to Microsoft. Each month, GDI sends Xandr a list of websites on this blacklist, said the source.

The Washington Examiner revealed on Thursday that it is on GDI’s list and spoke to an ad-buying source who said Breitbart News is also. Separately, GDI has said that the 10 “riskiest” news outlets for purported disinformation are the American Spectator, Newsmax, the Federalist, the American Conservative, One America News Network, the Blaze, the Daily Wire, RealClearPolitics, Reason, and the New York Post.

All those news outlets are legitimate, well established, and reasonable and reliable sources of information. No one should rely solely on them for their news, but to call their reporting “false,” “misleading,” “hate speech,” “reprehensible,” or “offensive” merely because they publish news from a conservative perspective is fundamentally dishonest. To then blacklist them because they have a different perspective is pure censorship by the left against its political opponents.

That the blacklist is definitely partisan is proven by the news outlets GDI has determined are acceptable.

Trio of colliding galaxies

Trio of colliding galaxies
Click for original image.

Cool image time! The picture above, cropped and reduced to post here, was taken by the Hubble Space Telescope and released today. From the caption:

Three galaxies stand together just right of centre. They are close enough that they appear to be merging into one. Their shapes are distorted, with strands of gas and dust running between them. Each is emitting a lot of light. Further to the left is an unconnected, dimmer spiral galaxy. The background is dark, with a few smaller, dim and faint galaxies and a couple of stars.

Astronomers estimate the colliding galaxies are about 50,000 light years from each other, which for galaxies is quite close. Eventually gravity will cause all three to merge into a single very large galaxy, its shape distorted by the merger. What that shape will be is one of the things astronomers are trying to figure out. At present their theories for galaxy evolution states that as galaxies grow by absorbing smaller nearby neighbors, they evolve from spirals to ellipticals, giant blobs lacking a distinct obvious structure.

One of Saudi Arabia’s two Axiom passengers later this year will be a woman

9:00 am

In announcing the two astronauts who will fly as passengers on Axiom’s commercial Ax-2 flight to ISS in the second quarter of 2023, Saudi Arabia also revealed that one will be the first female Arabian to fly in space.

Saudi nationals Rayyanah Barnawi and Ali al-Qarni will join the crew of the AX-2 space mission in an accomplishment that comes in line with the Kingdom’s Vision 2030. The spaceflight is set to launch from the United States to the ISS.

There is an aggressive space race now in the Middle East between Arab nations. The UAE started it by making space exploration a major goal for diversifying its economy. Saudi Arabia has now followed with its own program. Turkey, Bahrain, and Oman have also joined in.

SpaceX launches 55 more Starlink satellites

10:20 pm

Using its Falcon 9 rocket, SpaceX tonight successfully launched 55 Starlink satellites into orbit, lifting off from Cape Canaveral.

The first stage successfully completed its 12th flight, landing on a drone ship in the Atlantic. (These 1st stage landings have become so routine that no one at SpaceX even cheered tonight when the stage landed.) The fairing halves completed their 6th and 8th flights respectively. As of posting, the satellites had not yet been deployed.

The 2023 launch race:

10 SpaceX
5 China
2 Russia
1 Rocket Lab
1 Japan

Shortly after new Progress freighter docks with ISS, older Progress loses internal pressure

10:42 am

ISS as of February 11, 2023

Shortly after a new Progress freighter docked with ISS early today (shown as Progress 83 in the graphic to the right), the older Progress 82 lost internal pressure, possibly in its coolant system.

On February 11, Roskosmos, citing data from mission control, said that the Progress MS-21 cargo ship docked at the station lost pressure. According to the State Corporation, the hatch connecting the ship’s pressurized compartment with the rest of the station was closed and the vehicle was fully isolated from the ISS’ habitable volume.

…According to unofficial sources, the spacecraft lost all its cooling fluid from its Thermal Control System, SOTR. Several hours after the incident, NASA confirmed that the breach had been limited to the cooling system. At the same time, the US space agency said that the hatches between the cargo ship and the station had remained open, while temperatures and pressures aboard the outpost had remained normal. The subsequent publicly available exchange between the NASA mission control in Houston and a US astronaut Frank Rubio, aboard the ISS, indicated that the coolant system of the Progress MS-21 spacecraft had been completely emptied before the leak stopped.

The report is very unclear. In the first paragraph it suggests the freighter’s atmosphere had leaked out, while its hatches were closed and it was isolated from the station. The second paragraph suggests it only lost pressure and coolant from its coolant system, and the hatches had been open during the event.

Either way, this is the second Russian ferry spacecraft to experience such an event since mid-December, when the Soyuz capsule attached to ISS lost its coolant from what is believed to have been a small impact.

This particular Progress freighter is slated to be undocked from ISS on February 18th, when it will be de-orbited, burning up in the atmosphere over the Pacific. Thus, this leak appears to pose a relatively small risk to the station, as it probably has already been filled with station garbage and was likely ready for disposal anyway.

This incident however raises larger concerns. If it was caused by an impact from an external object, either micrometeorite or space junk, it suggests that the station might face a new increased risk of such events, quite possibly from debris from the Russian anti-satellite test in November 2021. As of November 2022 it was estimated that there were 444 objects still in orbit, with all but 18 expected to fall back to earth by 2025. It could be that one of those tracked objects hit ISS, or a different object that has not been tracked.

Or possibly we are seeing evidence of some quality control problem in the construction of these spacecraft, in Russia. Russia and NASA have still not revealed the results of the investigation into the hole that was drilled into the hull of a Soyuz capsule in 2018. Could there be some sabotage going on the ground in Russia that has not been identified that is designed to cause such leaks sometime after launch?

Some clarity on this issue is now becoming essential.

Terraced serrated layered mesas on Mars

Terraced mesas on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on November 19, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a collection of terraced mesas covered with dust of a variety of colors.

The bluish colors suggest exposed bedrock, while the different shades of tan suggest areas covered by dust and volcanic ash. That the tan areas are likely dust is strengthened in that it is found between and on these rough mesas, where dunes are also seen. The dust gets blown in but gets trapped there.

The tan colors however could also indicate different types of bedrock, especially because different terraces seem to be of different shades. We will need more data to determine which, or whether this is a combination of all these geological processes.

Curiosity looks into Gediz Valles
Click for original image.

Using its high resolution camera, the Curiosity science team has now released a November 2022 panorama looking south into Gediz Vallis, the Martian slot canyon that the rover will be entering in the near future.

The panorama above, cropped and reduced to post here, shows that canyon. The red dotted line indicates Curiosity’s approximate path since the panorama was taken, circling around behind Chenapua.

The mosaic is made up of 18 individual images that were stitched together after being sent to Earth. The color has been adjusted to match lighting conditions as the human eye would see them on Earth.

Not only should you definitely look at the original, at full resolution, but also compare it with the black and white mosaic I posted in December 2022, taken by the rover’s navigation camera looking in the same direction though from a slightly different position. The color definitely underlines the spectacular nature of the landscape.

NASA awards launch contract to Blue Origin’s unlaunched New Glenn rocket

9:09 am

NASA yesterday awarded Blue Origin the launch contract for its smallsat ESCAPADE Mars orbiter mission, set to launch in late 2024.

ESCAPADE will launch on Blue Origin’s New Glenn rocket from Space Launch Complex-36 at Cape Canaveral Space Force Station in Florida. Launch is targeted for late 2024. Blue Origin is one of 13 companies NASA selected for VADR contracts in 2022. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the VADR contracts. As part of VADR, the fixed-price indefinite-delivery/indefinite-quantity contracts have a five-year ordering period with a maximum total value of $300 million across all contracts.

NASA’s VADR program is designed to give contracts to higher risk contractors to help those launch companies develop their rockets. Since New Glenn is years behind schedule and as-yet unlaunched, this contract is an attempt to help change that. Note however that it is fixed price, and does not set a deadline for Blue Origin to launch.

ESCAPADE will actually be two orbiters designed to study the faint artifacts of Mars’ magnetosphere left over from its past.

India successfully launches its SSLV rocket on 2nd attempt

9:32 pm

On its second launch attempt tonight, India’s SSLV rocket (Small Satellite Launch Vehicle) successfully reached orbit and deployed all three of its smallsat payloads.

On the first launch attempt in August 2022, the engine on the fourth stage, used to put the satellites in their preferred orbits, shut down prematurely due to a failure of its guidance system. Today, all worked as planned.

The hope of India’s space agency ISRO is that this rocket can garner some of the growing smallsat business. That it is three years delayed because of ISRO’s panic over Wuhan makes fulfilling that hope more difficult, because so much of that business has now been grabbed by other companies.

The 2023 launch race:

9 SpaceX
5 China
2 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise still leads China 10 to 5 in the national rankings, and the entire world combined 10 to 9.

Pushback: Civil rights complaint filed against California school district for running segregated program

1:34 pm

Government endorsed segregation in California
Government endorsed segregation in California

“Segregation today, segregation tomorrow, segregation forever!” A civil rights complaint has been filed by the organization Parents Defending Education against the Pajaro Valley Unified School District in Santa Cruz County, California, for offering a segregated teacher support program that specifically excluded some races from attending.

As the program’s leaflet to the right shows, the program for “people of color” would not only give only certain races beneficial training, it would also give those participants “a stipend” that was forbidden to some employees due to their race.

It also appears that the program is also discriminatory on who it hires, as the coaches shown on that flyer are all minorities. Apparently, whites (and especially white males) need not apply.

SpaceX completes 33-engine static fire test today of Superheavy prototype #7

10:25 am

Two seconds after ignition
Today’s Superheavy static fire test

SpaceX today successfully completed a 7-second-long static fire test of 31 of 33 Raptor-2 engines at the base Superheavy #7. The test ran for its full duration, and it appears no damage occurred to the launchpad. One engine shut down prior to test, and one shut down prematurely during the test. If this had happened during launch, the booster would still have had enough energy to get Starship to its required velocity to reach orbit.

The company will now have to analyze the test to determine whether it was sufficient to proceed to a March orbital launch. Certainly they will roll the booster back to the assembly building to exchange out the two engines that misfired.

All in all, it appears an orbital test flight of Starship could occur sometime in the next two months, assuming the FAA gets out of the way and issues the launch license.

EARLIER UPDATE:
—————-
Propellant loading is underway, and a rough time estimate for the actual static fire test is now 3 pm (Central).

Musk has now confirmed in a tweet that they are going to proceed to the test. It now appears that they have almost completed propellant loading. It appears they have filled the oxygen tanks, but not the methane tanks, and will probably not fill the methane tanks entirely for the test itself.

Original post:
—————-
No specific schedule has been announced of SpaceX’s attempt today to complete the first full 33-engine static fire test in Boca Chica of its seventh prototype of Superheavy, but a live stream is available from NASAspaceflight.com. I have embedded that live stream below.

The test will validate numerous systems, including the ground systems, the launchpad, the engines, and the systems for igniting all 33 in the proper sequence. Starship prototype #24 is not stacked on top of Superheavy in order to prevent any damage to it in case this test goes ugly. If so, SpaceX already has Superheavy prototype #9 ready to go in the nearby assembly building.

Curiosity scientists find evidence of lake water higher on Mount Sharp than expected

10:14 am

Panorama as of January 17, 2023
Curiosity’s view of the marker band on January 17, 2023, the red dotted line the planned future route. Click for full image.

The science team for the Mars rover Curiosity today revealed that the marker band layer where the rover present sits shows some of the best evidence of liquid water and waves yet seen on Mount Sharp, and it has been found much higher on the mountain than expected.

Having climbed nearly a half-mile above the mountain’s base, Curiosity has found these rippled rock textures preserved in what’s nicknamed the “Marker Band” – a thin layer of dark rock that stands out from the rest of Mount Sharp. This rock layer is so hard that Curiosity hasn’t been able to drill a sample from it despite several attempts. It’s not the first time Mars has been unwilling to share a sample: Lower down the mountain, on “Vera Rubin Ridge,” Curiosity had to try three times before finding a spot soft enough to drill.

Scientists will be looking for softer rock in the week ahead.

As Curiosity climbs the mountain it transitions onto new younger layers of rock. Based on Curiosity’s earlier data lower down the mountain, scientists had assumed it had gone from layers that had been under a past lake to layers that were at the lake’s shoreline to layers where only running water once flowed. They had thought the marker layer and other higher layers would only show evidence of running water. Instead, in the marker layer they have once again found evidence of an ancient lake.

This quote by Ashwin Vasavada, Curiosity’s project scientist, sums things up nicely: “Mars’ ancient climate had a wonderful complexity to it, much like Earth’s.”

ISRO successfully test fires a throttleable version of an engine used in two of its rockets

10:03 am

ISRO on January 30, 2023 successfully completed a static fire test of a throttleable version of its Vikas rocket engine, used in the upper stage of both its PSLV and GSLV rockets as well as in the GSLV’S first stage, running the engine at 67 percent power for a time period of 43 seconds.

The ability to adjust the power level of the engine during launch will give ISRO the ability to attempt the recovery of the first stages, as well as expand the ability of these rockets to place more satellites per launch in different orbits.

UAE engineers shift Al-Amal’s orbit to do fly-bys of Mars moon Deimos

9:53 am

Engineers from the United Arab Emirates (UAE) yesterday revealed that they are in the process of changing the orbit of their Al-Amal Mars orbiter so that it will be able to do several close fly-bys of the Martian moon Deimos.

Two of the three required manoeuvres have already been made, allowing it to reach a new orbit between 20,000km and 43,000km with a 25-degree incline towards the planet. “Previously, we didn’t have any reason to move the orbit,” Ms Al Matroushi said. “But now we’re exploring a new adventure and science mission.”

Engineers are using the probe’s three main science instruments to capture images and data of the moon. These include an exploration imager ― a high-resolution camera ― to photograph the moon, and the infrared and ultraviolet spectrometers to measure its temperature and observe its thermophysical properties, including its regolith, or dust.

The first Deimos fly-by took place in late January, and as the probe moves to its closest approach to the moon, it will take high-resolution images.

Eventually Al-Amal will dip as close as 60 miles of Deimos.
