A tool that has helped guide sailors across oceans for centuries is now being tested aboard the International Space Station as a potential emergency navigation tool for guiding future spacecraft across the cosmos. The Sextant Navigation investigation tests use of a hand-held sextant aboard the space station.

Sextants have a telescope-like optical sight to take precise angle measurements between pairs of stars from land or sea, enabling navigation without computer assistance. NASA's Gemini missions conducted the first sextant sightings from a spacecraft, and designers built a sextant into Apollo vehicles as a navigation backup in the event the crew lost communications from their spacecraft. Jim Lovell demonstrated on Apollo 8 that sextant navigation could return a space vehicle home. Astronauts conducted additional sextant experiments on Skylab.

"The basic concepts are very similar to how it would be used on Earth," says principal investigator Greg Holt. "But particular challenges on a spacecraft are the logistics; you need to be able to take a stable sighting through a window. We're asking the crew to evaluate some ideas we have on how to accomplish that and to give us feedback and perhaps new ideas for how to get a stable, clean sight. That's something we just can't test on the ground."

The investigation tests specific techniques for using a sextant for emergency navigation on possible future space vehicles, such as Orion. With the right techniques, crews can use the tool to navigate their way home based on angles between the moon or planets and stars, even if communications and computers become compromised.

"No need to reinvent the wheel when it comes to celestial navigation," Holt says. "We want a robust, mechanical back-up with as few parts and as little need for power as possible to get you back home safely. Now that we plan to go farther into space than ever before, crews need the capability to navigate autonomously in the event of lost communication with the ground."

Early explorers put a lot of effort into refining sextants to be compact and relatively easy to use. The tool's operational simplicity and spaceflight heritage make it a good candidate for further investigation as backup navigation.

МОСКВА, 19 июн — РИА Новости. Инженеры Ракетно-космической корпорации (РКК) "Энергия" разработали материал для микрометеороидной защиты трансформируемых надувных модулей, который выдерживает попадание метеоритов диаметром больше сантиметра, сообщил во вторник сотрудник предприятия Леонид Бурылов.

Он представил на конференции в Москве презентацию, согласно которой испытания, проведенные в РКК подтвердили, что разработанные материалы выдерживают попадание алюминиевого шарика диаметром 11,5 миллиметра на скорости порядка 6,5 километра в секунду.

Бурылов уточнил, что создание трансформируемого модуля для складских целей и введение его в состав Международной космической станции позволило бы увеличить складской объем российского сегмента на 20 кубических метров.

Ранее сообщалось о том, что РКК "Энергия" разрабатывает трансформируемый модуль для МКС в инициативном порядке. Гендиректор предприятия Владимир Солнцев сообщал, что при инвестировании порядка 6-7 миллиардов рублей такой модуль можно будет отправить к станции в 2021 или 2022 году.

NanoRacks Deploys Largest Satellite From International Space Station To Date

June 20, 2018 //

Houston, Texas, June 20 2018 – Early this morning, NanoRacks successfully deployed the RemoveDEBRIS satellite from the International Space Station via the Company's commercially developed Kaber Microsatellite Deployer (Kaber). This is the third major microsatellite deployment for NanoRacks, and the largest satellite to ever be deployed from the International Space Station.

Спойлер

RemoveDEBRIS, one of the world's first attempts to address the build-up of dangerous space debris orbiting Earth, was launched to the Space Station via NanoRacks on the 14th SpaceX Commercial Resupply Mission in early April.

The satellite was designed, built and manufactured by a consortium of leading space companies and research institutions, led by the Surrey Space Centre at the University of Surrey and funded in part by the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement #607099. The consortium consists of: Airbus, Ariane Group (France); Surrey Satellite Technology Ltd (United Kingdom); Innovative Solutions In Space (Netherlands); CSEM (Switzerland); Inria (France); and Stellenbosch University (South Africa).

NanoRacks created the Kaber system to accommodate the increasing customer demand for commercial opportunities to deploy MicroSats from the International Space Station. Kaber offers deployments for satellites up to approximately 85 kilograms, and NanoRacks is able to provide Kaber launches on both SpaceX and Northrop Grumman Innovation Systems (previously Orbital ATK) commercial resupply missions.

The RemoveDEBRIS mission will perform four experiments, which will be tested on two CubeSats to-be-deployed from the larger satellite, acting as artificial targets. These experiments include both the first harpoon capture in orbit and a net that will be used on a deployed target. The team will also test a vision-based navigation system that uses cameras and LiDaR technology to observe CubeSats that will be released from the main spacecraft. Finally, the RemoveDEBRIS craft will deploy a large drag sail that will cause the orbit of the spacecraft to rapidly decay until it is destroyed in the Earth's atmosphere.

"It's wonderful to have helped facilitate this ground-breaking mission," says NanoRacks External Payloads Manager, Conor Brown. "RemoveDEBRIS is demonstrating some extremely exciting active debris removal technologies that could have a major impact to how we manage space debris moving forward. This program is an excellent example of how small satellite capabilities have grown and how the Space Station can serve as a platform for missions of this scale. We're all excited to see the results of the experiments and impact this project may have in the coming years."

Thank you to NASA's International Space Station Program Office and JAXA for their continued support of NanoRacks' International Space Station satellite deployment programs.

RemoveDEBRIS deployed into Low Earth Orbit from the ISS

Wed, 20 Jun 2018
The RemoveDEBRIS satellite has been deployed from the International Space Station via Nanorack's commercially developed Kaber Microsatellite Deployer (Kaber) - and became the largest satellite to ever be deployed from the ISS to date!

RemoveDEBRIS is an Active Debris Removal (ADR) technology demonstration mission which was launched to the Space Station via NanoRacks on the 14th SpaceX Commercial Resupply Mission in early April.

Photos on this page show NASA astronauts Commander Drew Feustel and Ricky Arnold last week as they tackled the loading of the spacecraft into the Kibo airlock. Photos are supplied courtesy of NASA/NanoRacks.

RemoveDEBRIS is being operated from SSTL's Spacecraft Operations Centre here in Guildford and we locked on to the satellite on its first pass over our ground station - telemetry from that first pass is nominal so we're officially into the spacecraft commissioning phase now.

The RemoveDEBRIS mission will perform four innovative ADR experiments, beginning in October with the deployment of a net developed by Airbus in Bremen which has been designed to capture a target cubesat. The mission is then scheduled to test a vision-based navigation system from Airbus in Toulouse and CSEM in Switzerland that uses 2D and 3D LiDaR (light dection and ranging) technology to track a cubesat released from the main spacecraft. Early in 2019 a harpoon developed by Airbus in Stevenage will be fired at 20 metres/second to penetrate a target made of composite material. Finally, the RemoveDEBRIS craft will deploy a large dragsail to speed de-orbit into the Earth's atmosphere.

Sir Martin Sweeting, our Chief Executive, says "SSTL's expertise in designing and building low cost, small satellite missions has been fundamental to the success of RemoveDEBRIS, a landmark technology demonstrator for Active Debris Removal missions that will begin a new era of space junk clearance in Earth's orbit."

Our thanks go to NASA's International Space Station Program Office, JAXA, Space-X and NanoRacks for getting RemoveDEBRIS safely into orbit.
