SpaceBok Hops Along

I have to say it, yes right here: I love this thing. According to the press release below, the SpaceBok could jump as high as 4 meters if it were on the moon! I was going to try and describe the motion then I thought a video would be perfect and then remembered the first video I saw of the SpaceBok and even found it – see below.

ESA’s caption: This walking and hopping robot is currently being tested in ESA’s Mars Yard.

SpaceBok is a quadruped robot designed by a Swiss student team from ETH Zurich and ZHAW Zurich, under the supervision of Professor Marco Hutter and PhD student Hendrik Kolvenbach, for future missions to the Moon or Mars.

“Legged robots can traverse unstructured terrain and could be used to explore areas of interest, such as craters, which rovers are unable to reach,” explains team member Patrick Barton. “As they are very versatile, they can change gait to adapt to different terrain.”

“In contrast to other legged robots, SpaceBok is primarily built for hopping,” adds team member Elias Hampp. “While this is not particularly useful on Earth, it could reach a height of four metres on the Moon. This would allow for a fast and efficient way of moving forward.”

““We are currently implementing and testing vision sensors, to increase SpaceBok’s autonomy and robustness,” says team member Radek Zenkl.

ESA’s 8 x 8 m Mars Yard ‘sandbox’, filled with different sizes of sand, gravel, and rock, is part of the Planetary Robotics Laboratory at the Agency’s ESTEC technical centre in Noordwijk, the Netherlands.

Leaving Mars – Fairwell MarCO’s

Another successful aspect of InSight mission was the two tiny cubesats MarCO’s A and B. The pair accompanied InSight on the journey to Mars and demonstrated their ability to act as communications relays.

The success of the MarCO satellites probably will ensured a bright future for such satellites in future mission. Well done!

NASA: MarCO-B, one of the experimental Mars Cube One (MarCO) CubeSats, took this image of Mars from about 4,700 miles (6,000 kilometers) away during its flyby of the Red Planet on Nov. 26, 2018. MarCO-B was flying by Mars with its twin, MarCO-A, to attempt to serve as communications relays for NASA’s InSight spacecraft as it landed on Mars. This image was taken at about 12:10 p.m. PST (3:10 p.m. EST) while MarCO-B was flying away from the planet after InSight landed.

Launch Pad Water Test

Testing a newly modified Ignition Overpressure Protection and Sound Suppression water deluge system at Kennedy Space Center’s Launch Pad 39B. The system mitigates the energy and heat during launch.

The system “dumped” about 450,000 gallons of water over the mobile launcher and flame deflector, the spectacular fountains shot water around 33 meters / 100 feet into the air.

Perhaps in the future NASA will produce a video of the pump-side of the system – I’d like to see those pumps.

New School Challenges from ESA

Bravo ESA, makes me wish I were a kid again!

ESA:  In the beginning of the World Space Week, ESA is proud to present two new school challenges: Climate Detectives and Moon Camp.

Meant for teams of school students guided by a teacher or educator, Moon Camp and Climate Detectives give young people the chance to run interdisciplinary projects and develop new skills, ranging from science and technology to teamwork and communication, like real space experts would do.

Moon Camp

With Moon Camp, ESA and Airbus Foundation, in partnership with Autodesk, challenge students to take part in the future exploration of space by designing a human shelter on the Moon! The students will have to design a 3D Moon Camp able to sustain the lives of at least two astronauts, taking into account:

  • the use of local resources, such as lunar soil and ice
  • technological solutions, such as power sources, a recycling system, a food growth chamber
  • protection  from meteorites and radiation

The Moon Camp challenge presents two separate categories featuring different levels of complexity:

  • Category 1, for students  up to 12 years old, using the 3D design tool Tinkercad® (free online tool) and
  • Category 2, for students between 13 to 18 years old, using the 3D design tool Fusion 360® (free for students and schools).

Teams can submit their design from 1 November 2018 until 16 March 2019.

Find out more about Moon Camp and help ESA settle on the Moon!

Climate Detectives

Climate detectives

With Climate Detectives ESA challenges students to make a difference in understanding and protecting Earth’s climate.Students will identify a climate problem by observing their local environment and will be tasked to investigate it as Climate Detectives. To this end, they will use available Earth Observation data coming from real satellites, or take measurements on the ground. Based on their investigation, teams will propose a way to help reduce the problem. The students will learn about climate on Earth as a complex and changing system and the importance of respecting our environment.

Climate Detectives is open to teams of students between 8 and 15 years old. The project is deployed in three Phases. Submission for Phase 1 is now open, and it will close on 15 November 2018.

So, do not hesitate any further and find out more about Climate Detectives. ESA needs you to make a difference by protecting Earth’s climate and helping our planet!

A GoPro Balloon Ride

A fun video.

A couple of links were included in the video description on YouTube:

A blog post on the launch and,

How to Send Your GoPro to space.

Since it is rather mountainous around these parts I won’t be trying this for fear of never being able to get to the returned camera. I do highly recommend taking a look at how it was done, very interesting. Also note if you might want to try this be very sure to check the regulations where you live! No need to create a hazard or get yourself into trouble.

Thanks to “BloonStu” for the entertainment!

Note: There may be a SpaceX launch later today, I hope to have a live link it does happen.

Gaia’s Star Density Map

A star density map composed by data obtained from second data release of Gaia – not to mention a very resourceful individual.

ESA: The second data release of ESA’s Gaia mission, made in April, has marked a turning point in the study of our Galactic home, the Milky Way. With an unprecedented catalogue of 3D positions and 2D motions of more than a billion stars, plus additional information on smaller subsets of stars and other celestial sources, Gaia has provided astronomers with an astonishing resource to explore the distribution and composition of the Galaxy and to investigate its past and future evolution.

The majority of stars in the Milky Way are located in the Galactic disc, which has a flattened shape characterised by a pattern of spiral arms similar to that observed in spiral galaxies beyond our own. However, it is particularly challenging to reconstruct the distribution of stars in the disc, and especially the design of the Milky Way’s arms, because of our position within the disc itself.

This is where Gaia’s measurements can make the difference.

This image shows a 3D map obtained by focusing on one particular type of object: OB stars, the hottest, brightest and most massive stars in our Galaxy. Because these stars have relatively short lives – up to a few tens of million years – they are mostly found close to their formation sites in the Galactic disc. As such, they can be used to trace the overall distribution of young stars, star formation sites, and the Galaxy’s spiral arms.

The map, based on 400,000 of this type of star within less than 10 000 light-years from the Sun, was created by Kevin Jardine, a software developer and amateur astronomer with an interest in mapping the Milky Way using a variety of astronomical data.

It is centred on the Sun and shows the Galactic disc as if we were looking at it face-on from a vantage point outside the Galaxy.

To deal with the massive number of stars in the Gaia catalogue, Kevin made use of so-called density isosurfaces, a technique that is routinely used in many practical applications, for example to visualise the tissue of organs of bones in CT scans of the human body. In this technique, the 3D distribution of individual points is represented in terms of one or more smooth surfaces that delimit regions with a different density of points.

Here, regions of the Galactic disc are shown with different colours depending on the density of ionising stars recorded by Gaia; these are the hottest among OB stars, shining with ultraviolet radiation that knocks electrons off hydrogen atoms to give them their ionized state.

The regions with the highest density of these stars are displayed in pink/purple shades, regions with intermediate density in violet/light blue, and low-density regions in dark blue. Additional information from other astronomical surveys was also used to map concentrations of interstellar dust, shown in green, while known clouds of ionised gas are depicted as red spheres.

The appearance of ‘spokes’ is a combination of dust clouds blocking the view to stars behind them and a stretching effect of the distribution of stars along the line of sight.

An interactive version of this map is also available as part of Gaia Sky, a real-time, 3D astronomy visualisation software that was developed in the framework of the Gaia mission at the Astronomisches Rechen-Institut, University of Heidelberg, Germany.
