- 🔒 Surfshark VPN is a tool that can change your IP address, making it appear as if you are connecting from a different country, which can help in accessing cheaper subscriptions and bypassing content restrictions.
- 🎥 The video discusses the Artemis program, which aims to send astronauts to the lunar surface for the first time since 1972, with updated equipment including the SpaceX Starship HLS and the Axium Extravehicular Mobility Unit (xEMU) suits.
- 👨🚀 Astronauts Doug Willock and Peggy Whitson tested the new xEMU suits in a full-scale model of the Starship HLS, providing valuable feedback on the suits' mobility and the interior of the Starship HLS.
- 🛰️ Machine learning and artificial intelligence are being used to detect Earth-like exoplanets through the radial velocity method, with an algorithm applied to three stars to identify potential exoplanets with simulated signals.
- 🚀 The first wooden satellite, developed by Japanese researchers, is set to launch aboard a SpaceX rocket in September, aiming to burn completely upon re-entry to avoid generating harmful metal particles.
- 🏳️ A special flag made of basalt fiber, designed to last longer in the harsh lunar environment, has been deployed on the Moon by the Chinese lunar mission Chang'e 6.
- 🌌 The basalt fiber technology has potential applications in space, offering thermal insulation and radiation resistance, which is crucial for lunar exploration.
- 🛰️ Space Case X01, a new thermal shield developed by Ariane Group, is designed to withstand intense heat during re-entry at speeds of 28,000 km/h, using a carbon fiber resin shield that also serves as the capsule's structure.
- 👩🚀 Astronauts from NASA are currently testing the Boeing Starliner spacecraft docked at the International Space Station to collect data for its certification by NASA, ensuring regular missions to the station.
- 🛰️ Despite some issues with the Starliner's RCS thrusters and helium leak concerns, the spacecraft has sufficient margin to allow for a return trip, with the mission team working on the return plan and safety measures.
Q & A
What is the main topic of the video script?
-The main topic of the video script is the latest developments in space news, including updates on the Artemis program, advancements in technology for space exploration, and the use of machine learning in detecting exoplanets.
Who is the sponsor of the 'Journal de l'Espace'?
-The sponsor of the 'Journal de l'Espace' is Surfshark VPN, which has been supporting the channel for three years.
What is Surfshark VPN and what does it offer?
-Surfshark VPN is a Virtual Private Network service that allows users to change their IP address, making it appear as if they are connecting from a different country. It can be used to access content that is available in different countries, such as streaming services and potentially cheaper subscriptions.
What is the significance of the Artemis program mentioned in the script?
-The Artemis program is significant as it aims to send astronauts to the lunar surface for the first time since 1972. It involves the development of new equipment, including the SpaceX Starship lunar lander and the Axium Extravehicular Mobility Units (AxEMU).
What are the Axium Extravehicular Mobility Units (AxEMU) and who developed them?
-The Axium Extravehicular Mobility Units (AxEMU) are new spacesuits developed specifically for the Artemis 3 mission. They are designed by Axium Space, and have been tested by NASA astronauts for the first time in a full-day test at SpaceX's headquarters.
How does the machine learning algorithm help in detecting exoplanets similar to Earth?
-The machine learning algorithm, based on a neural network, can analyze data from radial velocity methods used in exoplanet detection. It helps in identifying exoplanets with low mass and smaller influence on their host stars, which are harder to detect due to their subtle impact on the star's radial velocity.
What are the challenges faced by the Artemis program in comparison to the Chinese strategy?
-The Artemis program faces technical complexity and time pressure due to its strategy of not only conducting extravehicular activities (EVAs) on the lunar surface but also in space. In contrast, the Chinese strategy is more classical, inspired by the Apollo missions of the 1960s.
What is the first wooden satellite and why is it being developed?
-The first wooden satellite, called LigOSat, is being developed by Japanese researchers. It is made of wood to ensure that it burns completely upon re-entry into the Earth's atmosphere, avoiding the generation of harmful metal particles.
What is the significance of the basalt fiber flag deployed by the Chang'e 6 mission?
-The basalt fiber flag deployed by the Chang'e 6 mission is significant as it is designed to resist extreme temperatures, vacuum conditions, and intense ultraviolet radiation. It is the first flag to be deployed on the far side of the Moon and is made of a material that is more durable and cost-effective than traditional carbon or quartz fibers.
What is the purpose of the Space Case X-01 mission and its thermal shield?
-The Space Case X-01 mission aims to test a new carbon fiber resin thermal shield during re-entry at high speeds. The shield serves as a structure for the capsule, reducing weight and simplifying construction. The goal is to maintain internal temperatures below 60°C to protect the avionics.
What are the current issues being tested and monitored with the Boeing Starliner spacecraft at the International Space Station?
-The current issues being tested and monitored with the Boeing Starliner include power mode operations, life support consumables, habitability for a four-person crew, and the performance of the spacecraft's attitude control system. There are also concerns about a disabled RCS thruster and helium leaks in the service module.
