Inflatable Habitat May Become A Home On Mars

The B330 is an inflatable module that may someday enable humans to live and work in orbit around the moon, and even on Mars. The endeavor belongs to Bigelow Aerospace, a company that is now working with the United Launch Alliance (ULA) to get their inflatable lunar orbit station into space.

Compact, Lightweight, Suitable For Space

Bigelow Aerospace has had previous success launching inflatable units beyond Earth’s atmosphere. The company created BEAM (Bigelow Expandable Activity Module), which was added to the International Space Station (ISS) in 2016, extending the station’s living space after an easy set up. Other advantages that include durability and a compact, lightweight structure that lends itself well to transport aboard a cargo capsule.

Future Plans For Low Lunar Orbit

B330, the newest module, could be launched into low lunar orbit as soon as 2022 after hitching a ride on ULA’s Vulcan 562 rocket. This module is larger than BEAM, offering 330 cubic meters of volume—about a third of the size of the ISS. It’s spacious enough to accommodate a crew of six. Once B330 enters orbit around the moon, Bigelow Aerospace will outfit the habitat and ensure that it’s fully functional. It may then serve as a base for future Moon-based developments and as a training and research location for astronauts and long term space exploration prep.

Part Of A Return To The Moon

ULA and Bigelow Aerospace’s partnership on this endeavor—sometimes called “the lunar depot”—could be a springboard into more ambitious plans for returning to the Moon. While NASA has expressed interest in merging its own lunar exploration plans with Bigelow Aerospace and ULA, it’s not yet clear if, or how soon, funding for a return to the Moon will be available.

Electric Aircraft Makers Planning Affordable Shuttle Services

Aerospace engineers increasingly envision city skies buzzing quietly with electric air taxis. Known as eVTOL vehicles, or electric vertical take-off and landing aircraft, the zero-emission aircraft can launch and land like helicopters, but without the noise and fossil fuel consumption. Investors foresee them operating from urban “vertiports” that connect with large airports or shuttle people between regional cities. Electric aircraft could cost less to use than helicopters and provide a viable transportation option to the public.

Speed And Range Capabilities

Archer, an eVTOL startup, expects to unveil its first aircraft in 2024. Designers say that it will have a range of about 60 miles and be capable of a maximum speed of 150 mph. A 1-hour car ride could become a 15 or 20-minute flight.

Heavy eVTOL Investment

Seeing potential in these small, short-range passenger vehicles, United Airlines has invested in the eVTOL startup Archer and ordered 200 aircraft for a cost of $1 billion.

Automaker money is on the table too for eVTOLs. The merger of the automakers Fiat Chrysler and PSA Peugeot formed the company Stellantis, which has also invested in Archer.

The companies Solvay and Vertical Aerospace have agreed to collaborate and build an eVTOL. Solvay brings advanced composite and adhesive materials to the venture, and Vertical Aerospace specializes in sustainable aviation technologies. They plan to present the world with a working prototype, the VA-1X aircraft, by September 2021.

Safety And Cost Advantages

Electric motors are less vulnerable to breakdowns compared to conventional engines. Additionally, electric motors weigh less, which means a single aircraft could have many engines. Such redundancy would guard against the threat of total engine failure during a flight.

Electrical charging costs less than engines that directly burn fossil fuels. On top of reducing this expense, aerospace scientists are working toward autonomous eVTOLs operated by sophisticated software, which would eliminate the cost of paying a pilot.

How far do you think electric aerospace technology could go? Could it eventually work for long-range passenger flights?

NASA’s Chainmail Tire Is Ready For Extraterrestrial Terrain

What happens when your planetary rover punctures its wheel and the nearest service station is about 34 million miles away? That’s a real problem for NASA and their plans to send another rover to Mars in 2020. Curiosity, the rover currently exploring the red planet, has been hindered by punctures in its aluminum wheels, but a new type of tire could make travel much smoother for NASA’s future Mars missions.

Updating For Durability And Flexibility For The Unfamiliar

Based on the Resilient Wheel design from the original 1970 Lunar Roving Vehicle, a new type of airless, woven tire has been developed to prevent punctures and reliably travel across unfamiliar planetary terrain. After years of development and challenges in achieving the right balance of durability and traction, NASA engineer, Colin Creager and materials scientist Santo Padula created a stoichiometric nickel-titanium alloy wheel that’s durable, flexible, and is able to spring back to shape even after its deformed.

A Prototype With Promise

The wheel is comprised of a series of interlocking coils, similar to chainmail. While the original Resilient Wheel used steel mesh, the updated version provides better spring deflection and traction on rough terrain. Tests of the new prototype show promise, although NASA has not yet confirmed whether this specific design will be the one that’s used on its 2020 Mars rover. The chainmail wheels may however, play an integral role in the next crewed exploration vehicle, which would allow for speedier travel and more weight capacity than the Curiosity rover.

Will Limited Plutonium Supply Keep Future Space Missions Grounded?

Plutonium-238, or Pu-238, plays an important part in supplying electrical power to spacecraft when solar sources are insufficient. If supplies of Pu-238 aren’t maintained, future space travel could be compromised and that is a concern, as NASA and the Department of Energy (DOE)  are now facing new questions regarding a long term supply of this essential isotope.

Need For A Long Term Plan

Currently, the’s U.S.’s 35 kilogram stockpile of Pu-238 should be an ample supply for missions planned through the end of this decade, only one of which—the Mars 2020 rover—requires the use of radio thermoelectrical generator (RTG) that converts Pu-238 into electrical power. Beyond that, NASA and the DOE still need a long term plan to scale up the production of Pu-238. The prospect of future, manned space travel and other missions will depend on it.

Workforce And Production Obstacles

Major obstacles standing in the way of increased Pu-238 production are reported to include difficulties in hiring and training a qualified workforce and making improvements to, and scaling up, chemical processing methods. While the DOE has a goal to produce 1.5 kilograms of Pu-238 by 2025, the Government Accountability Office has said the department lacks a realistic long term plan to meet that goal.

Improved Efficiency Workarounds? 

Increased production of Pu-238 is not a new endeavor for NASA. The agency has had to restart production efforts as recently as 2011. Rather than simply work to maintain stock, NASA is also looking at ways to improve the efficiency of RTG so that reserves can be used for a greater number of future missions. There have been many previous attempts to develop a dynamic converter that would require significantly less Pu-238 to generate power but proposed concepts have not yet been proven viable.
