Will the Starship Make a 15 km Hop Test on Wednesday?

Update: According to FAA flight restrictions that were redacted yesterday (Dec. 3rd), the date for the hop test has since been moved to Monday, Dec. 7th, at the earliest. The altitude of the test has also been dropped from 15 km to 12.5 km (41,000 ft).

SpaceX has really hit its stride lately! Throughout the Summer of 2020 and well into the Fall, the company has experienced a string of successes with the construction and testing of its Starship prototypes. This has included multiple cryogenic load tests, static fire tests, test tank pressure tests, and even two 150 m (~500 ft) hop tests. And now, it looks like SpaceX could be making its first high-altitude flight test as early as tomorrow!

This test will see the first Starship prototype with three Raptor engines (SN8) fly to an altitude of 15 km (9.3 mi) before returning home safely. The engineering teams will be using this test to validate the Starship maneuvering fins as well, conducting a “belly-flop” maneuver that will see how the spacecraft’s aerodynamic surfaces allow it to make controlled landings on bodies that have an atmosphere.

The Moon has Resources, but Not Enough to Go Around

It’s no secret that in this decade, NASA and other space agencies will be taking us back to the Moon (to stay, this time!) The key to this plan is developing the necessary infrastructure to support a sustainable program of crewed exploration and research. The commercial space sector also hopes to create lunar tourism and lunar mining, extracting and selling some of the Moon’s vast resources on the open market.

Ah, but there’s a snag! According to an international team of scientists led by the Harvard & Smithsonian Center for Astrophysics (CfA), there may not be enough resources on the Moon to go around. Without some clear international policies and agreements in place to determine who can claim what and where, the Moon could quickly become overcrowded, overburdened, and stripped of its resources.

RocketLab Recovers a First-Stage Booster for the First Time: “Return to Sender”

In recent years, one of the most impressive developments for space exploration has been the rise of the commercial space industry (aka. NewSpace). Beyond fulfilling contracts with space agencies like NASA to provide commercial and crewed launch services, private aerospace companies are also fostering innovation that is helping to reduce the cost of sending payloads to space.

Take RocketLab, the US/NZ-based small satellite launch company that has broken new ground with its Electron rocket. In a further bid to reduce the costs of individual launches, RocketLab announced last year that it would begin recovering and reusing the spent boosters of its rockets. Recently, the company took a big step by successfully retrieving the first stage of an Electron after it delivered a payload to orbit.

Another Starship Test Tank is Pushed to the Limit and Explodes

They say that failure can be the greatest teacher of all, and it’s easy to see why. Those who learn from their mistakes become informed as to what can go wrong, and will develop the necessary strategies to avoid making the same mistake in the future. This philosophy is also at the core of SpaceX rapid-prototyping process, where full-scale models of the Starship and its components are tested to the point of failure.

At Boca Chica, SpaceX ground crews continue to follow this process in order to get the Starship ready for orbital testing. The latest piece of hardware that was tested to failure was the SN7.1 Test Tank, which was pressurized until it exploded. This test took place a week ago (on the evening of September 23rd) shortly after the SN5 and SN6 prototypes both completed a 150 m (~500 ft) hop test.

Astronauts are Getting a New Toilet Next Week

When astronauts have to go, NASA wants them to boldly go.

A new space toilet is heading to the International Space Station, with official name “Universal Waste Management System” (UWMS). (If it’s NASA, there has to be an acronym). The new toilet is smaller than the current toilets aboard the station, is more user-friendly, and includes 3-D printed titanium parts.

Design for a Space Habitat With Artificial Gravity That Could Be Grown Larger Over Time to Fit More People

There are two main approaches that humanity can take to living in space. The one more commonly portrayed is of us colonizing other celestial bodies such as the Moon and Mars. That approach comes with some major disadvantages, including dealing with toxic soils, clingy dust, and gravity wells.

The alternative is to build our own habitats. These could be located anywhere in the solar system, could be of any size that material science allows, and have different characteristics, such as temperature, climate, gravity, and even lengths of day. Unfortunately, we are still a very long way from building anything like a fully sized habitat. However, we are now one step closer to doing so with the release of a paper from a team at Texas A&M that describes a way to build an expandable space habitat of concentric cylinders that can house up to 8000 people.

The Space Court Foundation is Now in Session!

With the closing of the Apollo Era, the priorities of the world’s space agencies began to shift. Having spent the past two decades racing to send astronauts to orbit and to the Moon, the focus now changed towards developing the technologies needed to stay there. A new era of international cooperation, space stations, and partnerships between space agencies and commercial industry is what followed.

In the near future, things are expected to become even more interesting, with plans for the commercialization of Low Earth Orbit (LEO), the mining of Near-Earth Asteroids (NEAs), and the establishment of a permanent human presence on the Moon. Beyond the logistical and technical challenges this poses, there’s been no shortage of concern about the legal issues and implications this will raise as well.

To this end, a group of legal scholars and space experts recently came together to form the Space Court Foundation (SCF), a non-profit educational organization created to foster a conversation about these and other related space issues. By beginning the conversation now, they hope, the public will be able to play an active role in the burgeoning and evolving domain known as “space law.”

The SpaceX Starship Could be Making its Biggest Hop Yet (and a Belly-Flop) Next Month!

SpaceX is getting closer to the day when it will be able to make good on its promise of conducting regular missions to orbit, the Moon, and to Mars. At the heart of all this is the progress they are making with their Starship and Super Heavy launch system. In recent weeks, Musk’s commercial space company conducted two successful 150 m (500 ft) hop tests with the SN5 and SN6 prototypes at the Boca Chica launch facility in southern Texas.

Based on the latest announcements to come out of SpaceX, it appears that this recent string of successes has emboldened Musk and his company. Previously, Musk indicated that he was planning on making several more small hop tests and that the SN8 would attempt a 20 km (12 mi) flight sometime next year. More recent indications, however, suggest that Musk wants to conduct this high-altitude test before the end of October.

Electron Rocket’s 13th Launch Failed, Destroying its Satellite Payload

This past weekend (June 5th), the California and New Zealand-based aerospace company Rocket Lab suffered a terrible accident. During the 13th launch of their Electron rocket, an anomaly caused the second stage of the rocket to explode in midair. Luckily, there were no injuries, but the explosion did claim the mission payload, which consisted of satellites and commercial payloads for three different companies.

Behold! The Martian Menu, Courtesy of Mars City Design!

Today, there is no shortage of people who want to see humans go to Mars in their lifetime. Moreover, many want to go there themselves, and some even want to stay! It goes without saying that this proposed endeavor presents all kinds of challenges (the word Herculean comes to mind!) This is especially true when it comes to feeding future missions to Mars, not to mention permanent residents.

Regular resupply missions to Mars are simply not feasible, which means astronauts and settlers will have to grow their own food. To inspire ideas for how this could be done, and what the resulting meals would be like, Vera Mulyani and the organization she founded (Mars City Design) created the Martian Feast Gala. This annual event showcases what a Martian Menu could consist of and illustrates how every challenge is an opportunity to get creative!
