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 Cheif 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 crews 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.

Welcome back to our series on Colonizing the Solar System! Today, we take a look at that closest of celestial neighbors to Earth. That’s right, we’re taking a look at the Moon!
Chances are, we’ve all heard about it more than once in our lifetimes and even have some thoughts of our own on the subject. But for space agencies around the world, futurists, and private aerospace companies, the idea of colonizing the Moon is not a question of “if”, but “when” and “how”. For some, establishing a permanent human presence on the Moon is a matter of destiny while for others, it’s a matter of survival.
Not surprisingly, plans for establishing a human settlement predate both the Moon Landing and the Space Race. In the past few decades, many of these plansa have been dusted off and updated thanks to plans for a renewed era of lunar exploration. So what would it take to establish a permanent human presence on the Moon, when could it happen, and are we up to that challenge?

In addition to being the only solvent that is capable of supporting life, water is essential to life as we know it here on Earth. Because of this, finding deposits of water – whether in liquid form or as ice – on other planets is always exciting. Even where is not seen as a potential indication of life, the presence of water offers opportunities for exploration, scientific study, and even the creation of human outposts.
This has certainly been the case as far as the Moon and Mercury are concerned, where water ice was discovered in the permanently-shadowed cratered regions around the poles. But according to a new analysis of the data from the Lunar Reconnaissance Orbiter and the MESSENGER spacecraft, the Moon and Mercury may have significantly more water ice than previously thought.

The history of the Moon is a tale told by geology, apparent in its rocks, craters, and other surface features. For centuries, astronomers have studied the Moon from afar and for the past few decades, it has been visited by countless robotic missions. Between 1969 and 1972, a total of twelve astronauts walked on its surface, conducted lunar science, and brought samples of lunar rock back to Earth for study.
These efforts have taught us a lot about the things that have shaped the lunar surface, be they one-off events like the massive impact that formed the Shakleton crater to things that happened regularly throughout its 4.51 billion-year history. For instance, scientists recently discovered something unusual about the Antoniadi crater: a large boulder was perched on the rim of a smaller crater within after rolling about 1000 meters (1093 yards) downhill.

As NASA prepares to return to the Moon by 2024 as part of its Artemis program, the agency is focusing its efforts on exploring the Moon’s polar regions. These are areas of the Moon which seem to have a lot of water mixed in with the regolith.
