Since December of 2017, NASA has been working towards the goal of sending “the next man and first woman” to the Moon by 2024, which will be the first crewed lunar mission since the Apollo Program. As part of this mission, known as Project Artemis, NASA has been developing both the Space Launch System (SLS) and the Orion spacecraft, which will allow the astronauts to make the journey.
Originally, it was hoped that the first uncrewed flight of the SLS and Orion (Artemis I) would take place later this year. But according to recent statements by Associate Administrator Steve Jurczyk, this inaugural launch will most likely take place “mid to late” in 2021. This is the latest in a series of delays for the high-profile project, which has been making impressive progress nevertheless.

Ever since it made its historic landing on Jan. 3rd, 2019, the Chang’e-4 mission and its Yutu 2 rover have been busy exploring the lunar surface. Just recently, the mission passed its first year of operations and earned the distinction of being the first rover to travel a record 357.695 meters (1,173.5 ft) on the far side of the Moon. And in between all that, the mission has also provided some truly fascinating images of the lunar surface.
Thanks to a data release issued on Monday (Jan. 20th), the public can now peruse through all of the high-resolution images taken by the Chang’e-4 mission. The data, which was released by the Ground Research and Application System (GRAS) of the Chinese Lunar Exploration Project, includes images of the far side of the Moon that were taken with the lander’s terrain camera and the panoramic camera on the Yutu-2 rover.

China greeted the New Year with some impressive lunar milestones. For starters, last Friday (Jan. 3rd) was the first anniversary of the Chang’e-4 mission becoming the first robotic mission to make a landing on the far side of the Moon. A day prior, the Yutu-2 rover also celebrated the end of its 13th lunar day of science operations and the fact that it was the first rover to travel a record 357.695 meters (1,173.5 ft) on the far side of the Moon.

For decades, scientists have held that the Earth-Moon system formed as a result of a collision between Earth and a Mars-sized object roughly 4.5 billion years ago. Known as the Giant Impact Hypothesis, this theory explains why Earth and the Moon are similar in structure and composition. Interestingly enough, scientists have also determined that during its early history, the Moon had a magnetosphere – much like Earth does today.
However, a new study led by researchers at MIT (with support provided by NASA) indicates that at one time, the Moon’s magnetic field may have actually been stronger than Earth’s. They were also able to place tighter constraints on when this field petered out, claiming it would have happened about 1 billion years ago. These findings have helped resolve the mystery of what mechanism powered the Moon’s magnetic field over time.

Things are looking pretty good for Elon Musk and SpaceX, the company he founded back in 2002 with the intent of reinvigorating space exploration. In the last six months alone, SpaceX has deployed the first batch of its Starlink broadband internet satellites to space, conducted two successful untethered tests with the Starship Hopper, and finished work on the first orbital-class Starship test vehicle (the Mk.1).
And at the 70th International Astronautical Congress, which took place last week in Washington, DC, SpaceX president and Chief Operations Officer Gwynne Shotwell provided additional details about the Starship‘s mission timeline. As she indicated during a series of interviews, the company hopes to be sending the Starship to orbit next year, landing on the Moon by 2022, and sending payloads to the lunar surface by 2024.

When NASA sends astronauts back to the Moon and to Mars, the Orion Multipurpose Crew Vehicle (MPCV) will be what takes them there. To build these next-generation spacecraft, NASA contracted aerospace manufacturer Lockheed Martin. Combined with the massive Space Launch System (SLS), the Orion spacecraft will allow for long-duration missions beyond Low Earth Orbit (LEO) for the first time in over 50 years.
On Monday, Sept. 23rd, NASA and Lockheed Martin announced that they had finalized a contract for the production and operations of six missions using the Orion spacecraft, with the possibility of up to twelve being manufactured in total. This fulfills the requirements for NASA’s Project Artemis and opens the possibility for further missions to destinations like Mars and other locations in deep-space.

SpaceX is getting closer to its making its next big leap with the Starship super-heavy launch system. With hover tests now complete, the public is eagerly awaiting the completion of the full-scale prototypes and for orbital testing to begin. Never one to disappoint, Elon Musk has been posting regular updates on Twitter showcasing the latest progress of the Starship Mk.1 and Mk.2.

On Sunday (Sept. 8th), the Indian Space Research Organization (ISRO) announced that they had located Vikram, the lander element of their Chandrayaan-2 mission. The search began almost immediately after the space agency lost contact with the robotic spacecraft, which occurred moments before it set down on the lunar surface (on Friday, Sept. 6th).

Humanity’s future may lie in space, but getting out there is a very big challenge. In short, launching payloads into space from the bottom of Earth’s gravity well is quite expensive, regardless of whether or not reusable rockets are involved. And while some have suggested that building a Space Elevator would be a long-term solution to this problem, this concept is also very expensive and presents all kinds of engineering hurdles.
As an alternative, a pair of astronomy graduate students from the US and UK recommend an inspired alternative known as the Spaceline. This concept would consist of anchoring a high-tensile strength caple to the Moon that would extend deep within Earth’s gravity well. This would allow the free movement of people and materials between the Earth and Moon at a fraction of the cost.
When ‘Oumuamua crossed Earth’s orbit on October 19th, 2017, it became the first interstellar object to ever be observed by humans. These and subsequent observations – rather than dispelling the mystery of ‘Oumuamua’s true nature – only deepened it. While the debate raged about whether it was an asteroid or a comet, with some even suggesting it could be an extra-terrestrial solar sail.
In the end, all that could be said definitively was that ‘Oumuamua was an interstellar object the likes of which astronomers had never before seen. In their most recent study on the subject, Harvard astronomers Amir Siraj and Abraham Loeb argue that such objects may have impacted on the lunar surface over the course of billions of years, which could provide an opportunity to study these objects more closely.
