How recycled astronaut poop might sustain a mission to Mars

Posted by in categories: space travel, sustainability

Circa 2018


In the 2015 movie “The Martian,” astronaut Mark Watney survives on Mars by growing potato plants in his own waste. The scenario is fictional, of course, but it underscores a real-world challenge for NASA: How can the space agency ensure an uninterrupted supply of safe, nutritious food for astronauts who are tens of millions of miles from the nearest supermarket?

The successful launch of SpaceX’s Falcon Heavy rocket marked a big step toward developing the technology needed to transport colonists to Mars, though the strategy for keeping them and deep-space astronauts fed remains a work in progress.

NASA proposes a magnetic shield to protect Mars’ atmosphere

Posted by in category: space travel

This week, NASA’s Planetary Science Division (PSD) hosted a community workshop at their headquarters in Washington, DC. Known as the “Planetary Science Vision 2050 Workshop”, this event ran from February 27th to March 1st, and saw scientists and researchers from all over the world descend on the capitol to attend panel discussions, presentations, and talks about the future of space exploration.

One of the more intriguing presentations took place on Wednesday, March 1st, where the exploration of Mars by human astronauts was discussed. In the course of the talk, which was titled “A Future Mars Environment for Science and Exploration”, Director Jim Green discussed how deploying a could enhance Mars’ atmosphere and facilitate crewed missions there in the future.

The current scientific consensus is that, like Earth, Mars once had a magnetic field that protected its atmosphere. Roughly 4.2 billion years ago, this planet’s magnetic field suddenly disappeared, which caused Mars’ atmosphere to slowly be lost to space. Over the course of the next 500 million years, Mars went from being a warmer, wetter environment to the cold, uninhabitable place we know today.

Elon Musk is working on a rocket that can deliver weapons anywhere in the world

Posted by in categories: Elon Musk, military, space travel

The United States military has teamed up with Elon Musk and the company he heads, SpaceX. The goal of the tie-up is to build a rocket capable of delivering weapons anywhere on the globe in an hour. The benefits of quickly delivering weapons and other cargo anywhere on the planet very quickly are readily apparent.

The rocket would travel at 7500 miles per hour and would be able to carry 80 metric tons of cargo into orbit. The rocket could then land anywhere on the planet. The contract will see SpaceX begin by assessing costs and technical challenges for the project. Gen. Stephen Lyons, the head of US Transportation Command, said on Wednesday that initial tests are expected to begin in 2021.

What the military and SpaceX are trying to do is incredible. Using rockets to deliver massive payloads would allow the 7652 mile trip from Florida to Afghanistan could be completed within an hour. To compare, a C-17 Globemaster transport aircraft has a maximum speed of 590 mph and would require 15 hours to make the same journey.

The Pentagon Wants to Send Cargo Rockets Around the World in Minutes—with Elon Musk’s Help

Posted by in categories: Elon Musk, military, space travel

The Pentagon’s Transportation Command and Elon Musk’s SpaceX are teaming up to examine using rockets to ship cargo through space. The plan raises the prospect of sending urgently needed supplies to U.S. troops anywhere on Earth, within minutes. While the idea is technically feasible, there are several factors, including cost and preparation time, that could make it unworkable.

SpaceX crew launch delayed to assess Merlin engine concern

Posted by in categories: computing, Elon Musk, space travel

NASA said Saturday that the launch of four astronauts on SpaceX’s first operational Crew Dragon mission to the International Space Station has been delayed from Oct. 31 until “no sooner than early-to-mid November,” allowing time for SpaceX to resolve an issue with Falcon 9 rocket engines that halted a recent launch attempt with a GPS navigation satellite.

The engine concern appeared during an Oct. 2 launch attempt of a Falcon 9 rocket with a GPS satellite at Cape Canaveral, prompting computers controlling the final seconds of the countdown to abort the mission just two seconds prior to liftoff.

Elon Musk, SpaceX’s founder and CEO, tweeted after the abort that the countdown was stopped after an “unexpected pressure rise in the turbomachinery gas generator,” referring to equipment used on the rocket’s Merlin main engines. The gas generators on the Merlin 1D engines drives the engines’ turbopumps.
