Space Rider (courtesy: ESA) Launched on Vega-C, Space Rider will serve as an uncrewed high-tech space laboratory operating for periods longer than two months in low orbit. It will then re-enter the Earth's atmosphere and land, returning its valuable payload to eager engineers and scientists at the landing site. After minimal refurbishment it. Space-Rider is an European Space Agency Program devoted to the development of a reusable space transportation system capable of performing in-orbit operations as payload capturing from the International Space Station and Microgravity experimentation and then to land on a runway.

Space Rider combines reusability, in-orbit operations and transportation, and precise descent of a reentry vehicle able to safely traverse and land close to inhabited zones. These are major developments, set to extend European knowhow across a host of applications allowing industry to open up new markets.

Space Rider is an ESA program withthe objective to provide Europe with an affordable, independent,reusable end-to-end integrated space transportation system for routineaccess and return from low orbit. It will be used to transport payloadsfor an array of applications, orbit altitudes and inclinations. ¹⁾

Launched atop Vega-C, Space Riderfollows ESA's IXV (Intermediate eXperimental Vehicle) missionwhich on 11 February 2015 performed a flawless suborbital flight withatmospheric reentry and sea landing.

June 2017: Although Europe'sSpace Rider reusable spaceplane is three years or so from its debut,the European Space Agency is already making plans to privatize theunmanned orbital vehicle. ²⁾- By 2025, ESA officials said, Space Rider could be operatingcommercially, flying science payloads and bringing them back to Earthfor roughly $40,000/kg. Arianespace, the Evry, France-based launchservices provider, would likely serve as Space Rider's operator,offering industry and government customers the opportunity to fill thespaceplane 800 kg payload capacity with microgravity science, materialstesting, telecommunications and robotics demonstrations.

The Italian Aerospace ResearchCenter (CIRA) and Thales Alena Space manage ESA's Space Riderproject as co-prime contractors. Lockheed Martin is contributing to thedesign work. Funding for the program's design phase was approvedin December 2016 by ESA's 22 member states.

A 2020 test flight would see SpaceRider launch atop Arianespace's Vega-C rocket (which makes itsown debut in 2019) and land on a runway on one of the Atlantic'sAzores islands, Santa Maria.

During operational flights, SpaceRider will orbit 400 km above the Earth for a few months at the time,opening its payload bay doors to expose experiments to the spaceenvironment.

On 30 November 2017, TAS (ThalesAlenia Space) with ELV (European Launch Vehicle) as co-contractor, hassigned a contract with ESA for the engineering and preliminarydevelopment of the automated reusable Space Rider transportationsystem, designed for deployment by the new Vega-C light launcher intoLEO (Low Earth Orbit). ³⁾

Featuring a lifting bodyconfiguration, Space Rider is designed as a free-flying orbitalplatform, capable of remaining two months in orbit, safely reenteringthe atmosphere and landing. It can be recovered along with its payload,refurbished, and reused for up to six missions. It combines thecharacteristics of a space system designed for scientific experimentsin low Earth orbit with those needed for guidance outside theatmosphere and through an automated landing, including microgravityexperiments, in-orbit validations, testing of science and explorationtechnologies, etc., plus payload recovery on the ground for examinationand retesting.

Leading a consortium of Europeanmanufacturers, research centers and universities, Thales Alenia Spaceis responsible for the development of the reentry module (RM), derivedfrom the IXV. ELV is in charge of the development of the servicemodule, derived from the Vega-C upper stage AVUM (Attitude and VernierUpper Module). The partners in this new program are capitalizing on thelessons learned from the IXV, which enjoyed strong support from theItalian space agency ASI.

• The Storage pane of About This Mac is the best way to determine the amount of storage space available on your Mac. Disk Utility and other apps might show storage categories such as Not Mounted, VM, Recovery, Other Volumes, Free, or Purgeable. Don't rely on these categories to understand how to free up storage space or how much storage space is available for your data.
• When you duplicate a file on an APFS-formatted volume, that file doesn't use additional storage space on the volume. Deleting a duplicate file frees up only the space required by any data you might have added to the duplicate. If you no longer need any copies of the file, you can recover all of the storage space by deleting both the duplicate and the original file.
• If you're using a pro app and Optimize Mac Storage, learn how to make sure that your projects are always on your Mac and able to access their files.
