NASA Hubble Servicing Mission 4: 15th Anniversary Celebration (2009-2024)

NASA Hubble Servicing Mission 4: 15th Anniversary Celebration (2009-2024)

Fifteen years ago, a remarkable mission unfolded above the Earth. The Hubble Space Telescope, humanity's eye on the universe, received an unprecedented upgrade during its fifth and final Servicing Mission.

In May 2009, a brave team of astronauts embarked on a daring journey aboard Space Shuttle Atlantis. Their mission? To breathe new life into Hubble, ensuring its legacy of discovery could continue for years to come.

Space Shuttle Atlantis carried two new instruments to the Hubble Space Telescope, the Cosmic Origins Spectrograph and the Wide Field Camera 3. The mission also replaced a Fine Guidance Sensor, six gyroscopes, and two battery unit modules to allow the telescope to continue to function. The crew also installed new thermal blanket insulating panels to provide improved thermal protection, and a soft-capture mechanism that would aid in the safe de-orbiting of the telescope by a robotic spacecraft at the end of its operational lifespan.

The crew of STS-125 included three astronauts who had previous experience servicing Hubble. Scott Altman visited Hubble in 2002 as commander of STS-109, the fourth Hubble servicing mission. John Grunsfeld, an astronomer, has serviced Hubble twice, performing a total of five spacewalks on STS-103 in 1999 and STS-109. Michael Massimino served with both Altman and Grunsfeld on STS-109, and performed two spacewalks to service the telescope.

Polaris Dawn Crew Interview Ahead of All-civilian Spacewalk | NBC TODAY Show

Polaris Dawn Crew Interview Ahead of All-civilian Spacewalk | NBC TODAY Show

Polaris Dawn crew members Jared Isaacman, Sarah Gillis, Scott Poteet, and Anna Menon joined the TODAY show to share details about their upcoming historic mission as they get ready to attempt the first all-civilian spacewalk. The 5-day private mission is set to launch early summer on SpaceX’s Dragon X where they will also be testing out brand new spacesuits.

At ~700 km above Earth, the extravehicular activity (EVA) spacesuit will support the Polaris Dawn crew in the vacuum of space during the first-ever commercial astronaut spacewalk. A SpaceX Falcon 9 rocket will launch the Polaris Dawn mission from Florida. Dragon and the Polaris Dawn crew will spend up to five days in orbit. This Dragon mission will take advantage of Falcon 9 and Dragon’s maximum performance, flying higher than any Dragon mission to date by reaching the highest Earth orbit ever flown. Orbiting through portions of the Earth's Van Allen radiation belt, Polaris Dawn will conduct research with the aim of better understanding the effects of spaceflight and space radiation on human health.

Evolved from the Intravehicular Activity (IVA) suit, the EVA suit provides greater mobility, a state-of-the-art helmet Heads-Up Display (HUD) and camera, new thermal management textiles, and materials borrowed from Falcon’s interstage and Dragon’s trunk.

Building a base on the Moon and a city on Mars will require millions of spacesuits. The development of this suit and the execution of the spacewalk will be important steps toward a scalable design for spacesuits on future long-duration missions as life becomes multiplanetary.

Key Factors for China's Chang'e-6 Far Side Moon Polar Landing Site Revealed

Key Factors for China's Chang'e-6 Far Side Moon Polar Landing Site Revealed

China's Chang'e-6 lunar probe is the first human mission designed to collect and return samples from the far side of the Moon to Earth. Chang'e-6 arrived in lunar orbit on May 7, 2024. The landing location must consider the scientific significance and the engineering challenges involved. The Chang'e-6 lander relies on solar panels for power generation. Therefore, engineers must take into account the solar illumination available on the far side of the Moon to ensure mission success.

Chang'e-6's pre-selected landing area is located in the southern part of the Apollo basin in the South Pole–Aitken (SPA) basin (43°±2° south latitude, 154°±4° west longitude). The SPA basin is a large impact crater on the far side of the Moon. At roughly 2,500 km (1,600 mi) in diameter and between 6.2 and 8.2 km (3.9–5.1 mi) deep, it is the largest, oldest, and deepest basin recognized on the Moon.

"Our spacecraft depends on solar illumination for power generation, and this illumination varies with latitude. For this mission, we have selected a landing site in a region with moderate latitude. We chose the South Pole-Aitken Basin due to its adequate solar illumination and reliable communication signals, meeting the engineering standards," said Lu Yuntong, an engineer of China Aerospace Science and Technology Corporation (CASC).

"Globally, more than ten missions collecting and returning samples have been conducted from the near side of the Moon. However, there may exist even more ancient lunar soil on the far side. Thus, whatever samples we collect from the Moon's far side hold high scientific significance," said Lu.

The Chang'e-6 mission features scientific payloads from France, Italy, Sweden, and Pakistan. The international scientific payloads carried by the Chang'e-6 mission include the French radon gas detector (CNES), the European Space Agency/Swedish ion analyzer, and the Italian laser corner reflector (Agenzia Spaziale Italiana), as well as the Pakistani ICUBE-Q cube satellite. The mission will last about 53 days. 

In 2020, Chang'e-5 was the first lunar sample-return mission since the Soviet Union's Luna 24 in 1976. The mission made China the third country to return samples from the Moon after the United States and the Soviet Union.

China's Yutu-2 Far Side Moon Rover Continues 5-year Record of Operations

China's Yutu-2 Far Side Moon Rover Continues 5-year Record of Operations

China's Yutu-2 lunar rover has been working on the far side of the Moon for over five years, traveling a distance of more than 1,596 meters (1 mile) as part of the China Lunar Exploration Program (CLEP). Yutu-2 is currently operational as humanity's longest-lived lunar rover and the first lunar rover traversing the far side of the Moon. Yutu-2 is the robotic lunar rover component of the China National Space Administration's Chang'e 4 Mission to the Moon, launched on December 7, 2018. Chang'e 4 soft landed on the far side of the Moon on January 3, 2019. 

Yutu-2 has a radioisotope heater unit to maintain its subsystems during long and cold lunar nights. Electrical power is generated by the rover's solar panels during daylight.

Yutu-2 communicates with Earth via China's Queqiao-1 relay satellite in a halo orbit around the Moon. Queqiao-1 was launched in advance back in May 2018. Queqiao-1 is the first ever communication relay and radio astronomy satellite at the Moon. It was joined by China's second Earth-Moon relay satellite, Queqiao-2, in March 2024.

Direct communication with Earth is impossible on the far side of the Moon, since transmissions are blocked by the Moon. Communications must pass through a communications relay satellite, placed at a location that has a clear view of a landing site and the Earth.

Desde Chile descubren causas de la diversidad estelar en estrellas binarias

Desde Chile descubren causas de la diversidad estelar en estrellas binarias

Cosmoview Episodio 80: Utilizando el telescopio de Gemini Sur, ubicado en la Región de Coquimbo en Chile, un equipo de astrónomos confirmó por primera vez que las diferencias observadas en las estrellas binarias se deben a las diferencias químicas en la nube de material estelar de la cual se formaron. Los resultados ayudan a explicar por qué las estrellas que nacieron de la misma nube molecular pueden tener una composición química distinta y sistemas planetarios tan diferentes, además de plantear nuevos retos a los modelos actuales de formación estelar y planetaria.

Origin of Unexpected Differences in Giant Binary Stars Revealed | Gemini South

Origin of Unexpected Differences in Giant Binary Stars Revealed | Gemini South

Cosmoview Episode 80: Using the Gemini South telescope a team of astronomers have confirmed for the first time that differences in binary stars’ composition can originate from chemical variations in the cloud of stellar material from which they formed. The results help explain why stars born from the same molecular cloud can possess different chemical composition and host different planetary systems, as well as pose challenges to current stellar and planet formation models. It is estimated that up to 85% of stars exist in binary star systems, some even in systems with three or more stars.

"By showing for the first time that primordial differences really are present and responsible for differences between twin stars, we show that star and planet formation could be more complex than initially thought,” said Carlos Saffe of the Institute of Astronomical, Earth and Space Sciences (ICATE-CONICET) in Argentina who leads the research team. “The Universe loves diversity!”

This research was presented in a paper accepted in Astronomy & Astrophysics Letters.
