UAE Set as a Testing Ground for World’s Smallest Moon Rover With Legs

Published

on

The UAE has been confirmed as an official testing location for new space technology of the Spacebit ‘Spider Moon Rover’, the smallest robotic moon rover in the world with legs not wheels. A prototype of the UK’s first ever Lunar Lander – the Spacebit ‘Lunar Lander-Hopper’ will be unveiled at this year’s Dubai Airshow from the 17th to the 21st of November at DWC’s airshow site.

Built by Spacebit, one of the lunar economy’s brightest stars, the Spacebit ‘Lunar Lander-Hopper’ is due to be developed in the UK, in cooperation with leading aerospace company, Yuzhnoye Design Buro. The Lander-Hopper prototype and a 3D model of the Spider Moon Rover will be displayed by Spacebit on the Yuzhnoye Design Buro stand at the airshow. As the UAE continues making significant strides into space exploration, Spacebit has also confirmed that its ‘Spider Moon Rover’, is scheduled to be tested in the Emirates prior to its launch in spring 2020.

The ‘Spider Moon Rover’ is currently in its final development stage and along with tests in the UK, will be tested on suitable grounds similar to the moon’s surface in Abu Dhabi. Research on a precise UAE testing location is underway, with Jebel Hafeet in Al Ain proving to offer the ideal terrain needed for the world’s smallest robotic moon rover with legs instead of wheels. It’s the first time any lunar exploration vehicle with legs has been sent into space to explore the surface of the moon.

With caves or underground ravines that are close in structure to the lunar lava tubes, testing in the UAE will offer the Spacebit team a close assessment on how it will operate as it explores the moon’s surface. Speaking about the unveiling of the Lunar Lander-Hopper, Spacebit CEO and founder, Pavlo Tanasyuk, commented: “Our Lunar Lander is different as it incorporates the ability to hop from one landing site to another. It has embedded additional hardware, control and navigation software that will provide further on-surface mobility by repurposing it as a hopper.”

The multi destination lunar lander will be designed to deliver 150kg or more of payload to one landing point on the lunar surface or 50kg or more of payload to up to three remote landing points on the lunar surface with a distance of up to 20 km. What sets the Spacebit Lunar Lander-Hopper apart from other designs is that it can re-land once it has set down on the moon’s surface. The Spacebit Lunar Lander-Hopper will be deployed to the surface of the moon and, once areas of exploration interest are identified, it will then boost up and re-fly to its newly selected destination.

Its design makes it completely terrain-independent and capable of travelling vast distances on the lunar surface faster than conventional on-surface rovers. The Spacebit Lunar Lander-Hopper will take another two to three years to be fully complete, but the testing of the engines will happen earlier. Lunar landers are required to be fairly robust as the moon has a long solar day and night.

Landers can be in direct sunlight for around two weeks at a time and then in complete darkness for another two weeks. This can cause thermal control issues, for which the expertise of Yuzhnoye Design Buro will play a crucial role in overcoming those challenges. Yuzhnoye Design Buro Head and General Director, Alexander Degtyarev, commented: “This is an exciting partnership for Yuzhnoye Design Buro and Spacebit. We are pleased to be working with Spacebit as part of our new ‘powered by Yuzhnoye’ initiative which lets new space companies such as Spacebit, gain critical space flight expertise much faster by tapping into our existing rich technology base, whilst developing new technologies together.”

The Spacebit Lunar Land-Hopper prototype and Spider Moon Rover 3D model will be on display at the Yuzhnoye Design Buro stand (number 1510), at the Dubai Airshow from Sunday, 17th to Thursday, 21st November 2019.

Abu Dhabi-Based Khalifa University Develops 3D-Printed Glasses to Help Correct Colour Blindness

Published

on

Khalifa University of Science and Technology, a consistently top-ranked research-intensive university based in Abu Dhabi, has developed a new method to manufacture customized glasses using 3D printing that could help people with colour blindness. Colour Vision Deficiency (CVD) is an inherited ocular disorder that manifests itself by limiting the retina cones’ ability to transmit the whole spectrum of colours.

With red-green colour blindness being the most prevalent form of CVD, the most common way of dealing with everyday difficulties is by wearing tinted glasses. Now, a team of researchers from Khalifa University has developed lenses using transparent resin mixed with two wavelength-filtering dyes to provide a tinting effect. To customise the lenses and make them as similar as possible to commercially available products, the team used two dyes – one blocked the undesired wavelengths for red-green patients, while the other filtered unwanted wavelengths for yellow-blue patients, with volunteers for both groups attesting to the lenses’ efficacy.

Even though glasses based on this method are commercially available at present, they are not comfortable for wearing, nor optimizable. However, the Khalifa University research team has developed its own frames for the lenses, using 3D printing to optimize the frames for comfort and usability, making them as close as possible to regular glasses.

Dr. Haider Butt, Associate Professor, Mechanical Engineering, Khalifa University, said, “Our results showed that 3D printing had no influence on the wavelength-filtering properties of the dyes. In fact, the dyes remained unchanged as they were integrated with the resin and 3D printed. When we compared the optical performance of our glasses with commercial glasses for colour blindness, our results indicated that our 3D-printed glasses were more selective in filtering undesired wavelengths than the commercially available options. They have great potential in treating colour blindness, and their ease of fabrication and customization means they can be tailored to suit each individual patient.”

The glasses underwent several tests to address toxicity, durability, and longevity concerns. These tests included storing the glasses in water for over a week to analyze whether any dye would leak and leaving them out in the open under ambient conditions for another week. The glasses exhibited tensile strength and flexibility, proving their stability and long-lasting properties.

Khalifa University’s research outcome presents an opportunity for people with color blindness to mitigate their inability to distinguish between shades of certain colours that could restrict them from working in fields where color recognition is critical, in addition to carrying out everyday tasks. The research was funded by organizations from Abu Dhabi, including real estate developer Aldar Properties, and Sandooq Al Watan, a social initiative.

Emirates Mars Mission Tracks Martian Dust Storms

Published

on

The Emirates Mars Mission, the first interplanetary exploration undertaken by an Arab nation, is returning a number of unique observations of Martian dust storms, providing an unparalleled depth of information and insight into the way in which these storms evolve and spread across huge swathes of the planet.

Hope provides a powerful platform to observe details of the structure and variability of the Martian atmosphere.  Coordinated observations made by the EXI camera and the EMIRS infrared spectrometer characterize the thermal state of the surface and lower atmosphere and provide details of the geographic distribution of dust, water vapor, and water and carbon-dioxide ice clouds over time scales of minutes to days.

The EXI camera system collects images at three visible and two ultraviolet wavelengths – providing a multispectral “weather satellite view” of Mars.  The color composites presented here are assembled from images taken through EXI’s blue, green, and red filters (centered at 437, 546, and 635 nanometers).   These images are “calibrated” products that have removed many of the artifacts introduced by the camera system and also provide the observation geometry information to allow for mapping.  The contrast has been adjusted to enhance the visibility of the surface and atmospheric features.

EMIRS is an interferometric thermal infrared spectrometer (operating in the 6-40 micron wavelength range) that complements EXI in characterizing the lower atmosphere of Mars. EMIRS measurements are used to determine the distribution of lower atmospheric constituents such as dust, water ice, and water vapor (presented here as optical depth – related to the number of aerosols suspended in the atmosphere).

In addition, Mars surface temperatures and atmospheric temperature profiles up to 50 km from the surface are measured.  For the figures shown here, EMIRS data are averaged over an individual orbit of the Hope spacecraft (a time span of about 55 hours) to construct “globes” of dust optical depth (shown as shades of red, overlaid on a 3D map of surface elevations; these “globes” are centered at 4°N latitude, 100°E longitude).  The warming of the suspended dust by sunlight leads to increased atmospheric temperatures, which are also detected by EMIRS.

Rapid evolution
Starting in late December 2021, EXI and EMIRS monitored a rapidly-evolving regional dust storm as it expanded to a size of over several thousand km.  A series of EXI and EMIRS “globes” are presented here (orientated with north to the top), documenting the growth and dissipation of the storm over nearly two weeks.

The prominent dark “shark’s fin” feature in the EXI images is known as Syrtis Major. In this area, thin deposits of dark basaltic sand cover the surface of a gently-sloping shield volcano.  To the south, the tan circular feature is the Hellas impact basin (the largest crater on Mars – about 2300 km across, and up to 7 km deep) – often shrouded in dust and water-ice clouds.  In both the EMIRS and EXI globes, a green star marks a “reference location” (an 85-km diameter impact crater) to visually aid tracking features in both data sets.

On 29 December 2021 (EMM orbit number 153), EXI captured a fully illuminated disk of Mars nearly centered on Syrtis Major (image center: 24.6°S, 81.1°E). It was mid-winter in the southern hemisphere (Ls = 149°).  As is typical for this season, the atmosphere was relatively clear, with only thin water-ice clouds visible over the plains to the east of Syrtis.  As is also typical, Hellas appeared to be filled with tannish dust clouds, obscuring deposits of surface ice mantling the southern portion of the basin.  The EMIRS observations during this time confirm the relatively thick dust clouds in Hellas but detect only low amounts of suspended dust elsewhere. This set of EXI and EMIRS observations provides a baseline to compare with the subsequent views of Mars obtained over the following two weeks.

On 5 January 2022 (EMM orbit number 156), EXI obtained this half-illuminated view of Mars (image center: 12.3°S, 94.8°E) — the sun was just setting near the center of the disk.  Apparently forming over the previous week, a massive dust storm (about 2500 km across) was approaching from the east and was partially obscuring Syrtis Major; greyish water-ice clouds are also evident in this storm.  Hellas was completely shrouded by dust clouds.  The EMIRS observations clearly show the high concentrations of dust in the Syrtis and Hellas dust storms, with a “dust haze” extending far to the east.

On January 7, 2022 (EMM orbit number 157), this mid-day EXI observation better reveals the extent of the dust haze and greyish water-ice clouds spreading to the east of Syrtis Major and to the north of Hellas (image center: 22.8°S, 97.9°E).  The EMIRS data reveal the increasing thickness of this diffuse dust haze, suggesting the active lifting of dust from the surface extending at least 4000 km eastward from Syrtis Major.

On January 9, 2022 (EMM orbit number 158), EXI observed a fully illuminated hemisphere centered on Syrtis Major (image center: 22.7°S, 62.6°E).  The dust-lifting has extended to the west, with a discrete multi-lobed dust storm (about 1200 km across) swirling over northwestern Syrtis.  The dust haze is very prominent covering the plains eastward from Syrtis.  Again, EMIRS reveals the extent of the dust clouds – dramatically portraying the increased dust optical depth from NW of Syrtis all the way to the eastern limb of the map – spanning about 1/3 of the circumference of Mars!  Compare this set of observations with the relatively clear conditions prevailing on 29 December 2021!

The final time step is for January 14, 2022 (EMM orbit number 160).  EXI shows a late-afternoon (nearing sunset) view of Syrtis Major (image center: 8.5°S, 117.0°E).  No discrete dust storms are visible; instead, a pervasive dust haze partially obscures and extends eastward from the entire Syrtis Major/Hellas region.  EMIRS data also indicate the thinning of the haze, with the amount of dust significantly reduced.  The continuation of the dust veil to fill the Hellas basin is evident in both the EXI image and EMIRS map.

As the Martian season approaches southern spring, dust storm activity typically becomes more pervasive.  The Hope observatory is a valuable orbiting asset in documenting the location and evolution of dust storms on the planet, giving unprecedented observations and insight into the nature of these storms and their characterisation.
