Cameras

noreply@blogger.com (Simon O'Reilly) — Thu, 02 Feb 2012 17:15:00 +0000

It just wouldn't be as fun sending a spaceship to the moon if we couldn't have a look around with it once it's there. Also we wouldn't be able to meet the requirements of the GLXP either, so the Lander and Rover will both be equipped with cameras. The Lander's camera can operate both in still image mode and in video mode at 10 to 15 frames per second. It is mounted on an arm extending from the side of the Lander between the two egress ramps. It will be used to film the descent of the spacecraft to the moon as well as the Rover as it disembarks from the Lander and begins its lunar journey.

The Rover's camera can also capture still images as well as video footage. It will be used to film the journey across the moon and capture the high definition footage of the lunar surface which must be beamed back to Earth to complete the GLXP mission. White Label Space intends to use commercially available, rugged cameras which will be subjected to a full space-qualification program. The team is currently looking for industrial partners to provide the cameras used on the mission. This would be yet another one-of-a-kind marketing opportunity for any interested companies as the cameras used to capture the first images from the moon's surface for over 40 years will surely gain world-wide exposure. No pun intended!

Preparations on Leg Assembly and Panel Joints

noreply@blogger.com (Andrew Barton) — Mon, 23 Jan 2012 09:28:00 +0000

This video shows some work on the carbon fibre leg assembly in preparation for Drop Test #2 and an experiment on a novel type of insert for joining together the carbon fibre honeycomb panels of the lander structural model. Looking for cheap, quick solutions that give almost similar performance to traditional methods, White Label Space GLXP team is continuing to seek low-cost techniques for the lander design.

White Label Space Teams up with EarthSpace!

noreply@blogger.com (Simon O'Reilly) — Sun, 15 Jan 2012 21:13:00 +0000

White Label Space has finalised a new partnership with EarthSpace, a research and implementation organisation with interests in space exploration, satellite applications, climate change and sustainable energy. EarthSpace and White Label Space will coordinate efforts to promote the EarthSpace mission to inspire students to pursue scientific careers and to help them and the general public to recognize the relationship between scientific and non-scientific fields through an Earth and Space Exploration paradigm. White Label Space will cooperate with EarthSpace to facilitate participatory space exploration projects as part of EarthSpace programs, further raising awareness of the general public to current space exploration programs and competitions like the Google Lunar X PRIZE.

Free TV Udine Interviews Andrea Gini

noreply@blogger.com (White Label Space) — Sat, 14 Jan 2012 11:09:00 +0000

This video (in Italian) is an interview of Andrea Gini by Free TV Udine. The interview covers Andrea's work on the touchscreen rover navigation software called Kaizen, which he developed with the Tohoku University's Space Robotics Lab.

The Lunar Lander

noreply@blogger.com (Simon O'Reilly) — Thu, 12 Jan 2012 11:38:00 +0000

The Lander vehicle has been designed entirely by the White Label Space team. The main body of the Lander is shaped like a hexagon. On three of its six sides the landing legs will be attached and the remaining three sides will be unobstructed to permit accommodation of equipment and payload units that require external view factors. The landing legs provide excellent support points for on-board equipment which would otherwise apply high cantilever loads to the Lander’s sides during various mission stages.

It’s impossible to predict the exact landing site of the WLS spacecraft on the moon and there could be obstacles which could block the Rover’s path. For this reason the Lander has been designed with not one but two egress ramps which the Rover can use to reach the moon’s surface, if one is blocked then the Rover can use the other. The ramps are attached to two of the sides where landing legs are attached to make use of the support that they can provide. Attached to the third leg is the High Gain Antenna which is used to transmit data between the Lander and the team controlling it on earth. The Rover sits atop the Lander and is held in place by a Hold-Down and Release Mechanism (HDRM) based on a pyrotechnic bolt which will be detonated to release the Rover after landing.

As White Label Space's GLXP mission will be financed by advertisements the naming of the Lunar Rover is for sale. So any companies wishing to seize an opportunity to have their brand forever associated with mankind's return to the moon should contact the White Label Space team. Sponsoring the GLXP mission could lead to the headlines around the world telling of how the " Rover" was the first privately funded craft to explore the moon's surface; don't miss this chance to make marketing history!

Lander Propulsion System

noreply@blogger.com (Simon O'Reilly) — Tue, 03 Jan 2012 13:15:00 +0000

Unlike the other rocket engines used during the GLXP mission, the propulsion subsystem used to control the descent of the Lander is being developed by the White Label Space team. The engine will use hydrogen peroxide and kerosene as propellants. A key benefit to using these chemicals is that they are non-toxic thus making them much safer to handle. This permits low cost testing, at least an order of magnitude cheaper than what is possible with toxic propellants such as the hydrazine types. The engine can be operated in monopropellant mode by allowing the hydrogen peroxide to decompose into oxygen and superheated steam. Then by mixing these chemicals with the kerosene spontaneous combustion will ignite the engine which eliminates the need for a dedicated igniter. All in all, the system being developed by WLS will not only reduce costs thanks to the use of non-toxic propellants but also provide reliable control of the Lander's descent to touchdown.

Breaking, Descent and Landing

noreply@blogger.com (Simon O'Reilly) — Mon, 19 Dec 2011 23:01:00 +0000

Now here is where the fun really begins, it's not every day you land a robot on the moon! The Breaking Stage solid motor is used to reduce the spacecraft's speed on its approach. The direct descent landing trajectory chosen means the Lander can touch down just after lunar dawn allowing the maximum amount of time to complete the mission but also requires the timing of this burn to be very precise. To achieve this precision an on-board timer is used to trigger the ignition when the Lander passes through a specific lunar altitude. After the Lander separates from the Breaking Stage it follows a gravity turn trajectory (illustrated in the image) to the surface using its own rocket engine to control its descent. During the final approach to touchdown the Lander determines its altitude and vertical velocity using a small radar altimeter and its horizontal velocity by a landing camera coupled with the altimeter and rate gyros. Finally, after travelling a quarter of a million miles, the Lander touches down on the moon's surface and prepares to deploy the Rover and complete the GLXP mission.

Guidance and Navigation Control

noreply@blogger.com (Simon O'Reilly) — Wed, 14 Dec 2011 11:06:00 +0000

Throughout the mission it is vital that the position and orientation of the spacecraft are precisely known so that it can be guided to the chosen landing site on the moon. Standard ground tracking techniques are used to accomplish this.

Soon after the Trans Lunar Injection burn and stage separation, a first Mid-Course Manoeuvre (MCM) is performed using the Braking Stage Reaction Control System. A sufficiently large delta-V for the MCM is provided for this burn that serves to compensate for injection inaccuracies of the solid motor. One or more subsequent MCM manoeuvres are performed throughout the rest of the lunar transit to accurately target the landing site. Following this the breaking stage is used to slow the spacecraft to a safe velocity for landing on the moon.

Attitude Control

noreply@blogger.com (Simon O'Reilly) — Thu, 08 Dec 2011 00:19:00 +0000

The orientation or attitude of the spacecraft is critical at all stages of the mission. After the Trans Lunar Injection stage is complete the spacecraft stack begins its three day long journey to the moon. The difference in temperature between the side exposed to the sun and the side in the shade can be as high as 135 degrees. This temperature gradient can cause structural damage to the spacecraft and effect the performance of the Breaking Stage solid motor. To ensure that the temperature is distributed evenly a monopropellant Reaction Control System (RCS) is used to slowly spin the spacecraft about the flight axis.

The RCS is also used to perform any Mid-Course Manoeuvres (MCMs) needed during the lunar transit and to optimise the spacecraft's attitude for the breaking burn on approach to the lunar surface.

Lander Drop Test 1

noreply@blogger.com (White Label Space) — Mon, 05 Dec 2011 10:15:00 +0000

The White Label Space engineering team conducted a first proof-of-concept test of a new concept for impact absorbing legs. Making best use of available hardware, the team integrated the new trial leg assembly on the existing mock-up of the lander. A sensor system was used to measure accelerations during the drop.

Trans Lunar Injection (TLI) Stage

noreply@blogger.com (Simon O'Reilly) — Mon, 05 Dec 2011 02:32:00 +0000

The Polar Satellite Launch Vehicle can be used to launch the spacecraft stack into Geostationary Transfer Orbit (GTO) but then a second rocket impulse is needed to transfer from this orbit into the Lunar Transfer Orbit (LTO) required to complete the mission.

This part of the mission is referred to as the Trans Lunar Injection (TLI) stage and is accomplished using a Star30BP solid motor. The spacecraft is first stabilised by spinning it about its flight axis using a small motor which thrusts in the tangential direction before the Star30BP fires to inject the stack into LTO. A yo-yo de-spin mechanism is used to slow the craft's rotation after the TLI stage is complete, a video demonstrating a yo-yo de-spin can be viewed here. If either the Soyuz Fregat or Falcon 9 launch vehicle is used then the spacecraft stack is placed directly in LTO so the separate TLI stage rocket is not needed.

The Launch Vehicle

noreply@blogger.com (Simon O'Reilly) — Fri, 02 Dec 2011 14:18:00 +0000

Every space mission begins with a rocket launch and the mission planned by White Label Space is no different. The launch will place the spacecraft in a parking orbit above the earth before it is propelled further to LTO (Lunar Transfer Orbit). From here the spacecraft follows an orbit which brings it increasingly under the effect of the moon’s gravity until, after a three day journey, it reaches the moon.

The launch will be carried out using one of three low-cost launch vehicles with which the spacecraft stack designed by White Label Space is compatible; the Polar Satellite Launch Vehicle (PSLV-XL) developed in India, Russia’s Soyuz Fregat or SpaceX’s Falcon 9.

The larger size of the Soyuz Fregat and Falcon-9 launchers allows for additional payload capacity. These launch vehicles could carry one or more other passenger spacecraft to LTO, potentially including other GLXP competitors. This would considerably reduce the launch costs incurred by each organisation and so offers a clear financial advantage to any private or government funded missions.

While the Soyuz and Falcon launch vehicles can deliver a payload directly to LTO the PSLV-XL does not have this capability and so an additional rocket would be needed to perform what is known as a TLI procedure (Trans Lunar Injection). Once the TLI stage rocket has inserted the stack into LTO, it separates and is discarded, leaving the three remaining components of the spacecraft stack; the braking stage, Lander and Rover, to continue on their course to the lunar surface.

Greatest Space Ads - China's Lenovo Stakes Claim in Commercial Space

noreply@blogger.com (Andrew Barton) — Thu, 27 Oct 2011 18:41:00 +0000

Chinese electronics giant Lenovo has entered the commercial space race with a space-linked advertising campaign. Lenovo is supporting the YouTube Space Lab, a competition for teenagers to design experiments to be conducted in space.

Two winners of the competition will attend astronaut training in Russia and have their experiments performed aboard the International Space Station, and streamed to Earth. YouTube also joins the party by streaming the experiment down to Earth.

This is a keen marketing move by Lenovo, linking its brand the to dreams of today's youth while placing itself in the high-tech frontier of spaceflight. It should come as no surprise that Lenovo is interested in space since the Chinese Academy of Sciences (CAS) is a major shareholder. The chief scientist of China's lunar exploration program, Ouyang Ziyuan, is in fact an academician at CAS (see here).

Andrea Gini is Editor-in-Chief of the Space Safety Magazine

noreply@blogger.com (Andrew Barton) — Thu, 27 Oct 2011 14:19:00 +0000

White Label Space team member Andrea Gini is now Editor-in-chief of the Space Safety Magazine, a magazine published by the International Association for Advancement in Space Safety (IAASS) and the International Space Safety Foundation (ISSF), both non-profit organizations promoting the safe and sustainable use of space.

Starting in July, the Space Safety Magazine has evolved from a traditional document-based distribution to a paper magazine, complemented by a full-blown blog with daily updates on all the latest news and trends in the area of spaceflight safety.

We are very happy that Andrea is supporting the magazine whilst also remaining an active member of White Label Space. Indeed his work in that area is also relevant to the Google Lunar X PRIZE. Andrea describes the overlapping interests with the following comments:

"Poor attention, lack of technical progress in the field, cumulative effects, and weak or non-existent international rules are some of the risks that the space industry is facing nowadays."

"Safety risk in space missions refers to the general public safety (on ground, on air and at sea), safety of launch range personnel, and safety of humans on-board. Space safety is also generally defined in a wider sense as encompassing the safeguard of valuable facilities on ground (e.g. launch pads), of strategic and costly systems on orbit (i.e. global utilities), payloads as well as the safeguard of the space and Earth environment."

"Every space mission, especially those promoted by the the private sector like the GLXP, needs to take into account all these issues if they want to achieve the goal to lower the cost of access to space."

In his role as Chairman of IAASS Information and Communication Committee, Andrea developed the magazine to promote the IAASS and the ISSF, and their initiatives. Written by space safety specialists and by professional scientific journalists, the magazine targets the wider audience of those who have an interest, need or simple curiosity to know the current developments in the field of space safety and sustainability.

Andrea has even offered to mentor a White Label Space team members interested to bring some of his high-quality blogging and publishing know-how to the White Label Space blog. We are currently looking for volunteers interested to work with Andrea's to support and enhance this White Label Space blog.

WLS Japan Engineering Meeting

noreply@blogger.com (White Label Space) — Mon, 24 Oct 2011 16:36:00 +0000

The White Label Space Japan (WLS-J) team has started recruiting engineers to support the construction of a second rover prototype that will be dedicated to promotional activities such as the upcoming "Rover Challenge", a series of field demonstrations at famous Japanese sights.

The photos below show some of the action from the first engineering meeting.

The meeting included discussions about the specifications for the next prototype (no major modifications are foreseen) and the planning for the engineering work that needs to take place. The next step will be to agree on the form of the new WLS-J engineering unit that will be responsible for the new prototype's production and later the rover flight model for our GLXP mission.

From around March next year the new prototype will be available for the Rover Challenge promotional tour.

The existing rover prototype will remain with Tohoku University for further developments.

WLS-J is steadily growing, and has started to expand its weekly meetings in Tokyo into dedicated sub-teams covering issues such as promotion, business development and legal.
