Instead of Going Straight to Mars, Astronauts Should Make a Slingshot Past Venus First

Every 26 months, the orbits of both Earth and Mars conspire to make travel between the two planets shorter. Launching in one of these windows means the travel time can be reduced to only six months. Our robotic missions to the Martian surface, and missions that place satellites in Martian orbit, launch during these windows.

But are there other alternatives to this mission architecture?

One group of researchers says that crewed missions to Mars shouldn’t go directly to their destination; they should slingshot past Venus first.

15 Different Ideas for Rovers That Could Explore Venus

NASA and many other space agencies around the world are eager to get back to Venus. And this time around, they want to send missions that can explore the surface for more than a few hours! To this end, engineers at NASA’s Jet Propulsion Laboratory (JPL) and Glenn Research Center (GRC) are investigating “steampunk” concepts and special electronic systems that will allow rovers to work in Venus’ hellish environment.

In February of 2020, NASA also launched a public competition through HeroX to seak ideas for rovers that would be capable of surviving the extreme conditions on Venus’ surface – the “Exploring Hell Challenge“. After months of consideration for all the worthy submissions they received, NASA recently announced that it in addition to three winning concepts, they have selected two additional finalists and ten honorable mentions!

NASA Chooses 10 Projects that Will Help it Live Off the Land… on the Moon

Before this decade is out, NASA plans to send astronauts to the Moon for the first time since the Apollo Era and establish a sustainable program of lunar exploration. In order to ensure that future lunar missions are cost-effective and not entirely dependent on Earth for resupply, NASA is looking for ways to leverage lunar resources – everything from water ice to oxygen-rich regolith – to meet their astronauts’ needs.

This process, known as In-Situ Resource Utilization (ISRU), is a major part of NASA’s plans to explore the Moon in the coming years, as well their long-term plans to send astronauts to Mars. To help them meet this challenge, NASA recently selected 10 proposals through its Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) program to developed ISRU-related technologies.

NASA and HeroX are Looking to Light Up the Moon!

NASA is busy preparing to land astronauts around the Moon’s South Pole-Aitken Basin by 2024, which will be the first time astronauts have walked on lunar soil since the Apollo Era. By 2028, they plan to establish the Lunar Gateway and Lunar Base Camp, which will facilitate long-term lunar exploration and also missions to Mars. Naturally, a lot of things need to be figured out beforehand, like seeing to the astronauts’ needs.

This includes shelter from the elements, food, and water, but also electricity. To meet that demand, the NASA Centennial Challenges Program has once again launched an incentive challenge through HeroX to inspire solutions. It’s called the Watts on the Moon Challenge, and in exchange for a prize purse of up to $5 million, NASA is looking for solutions on how to provide a reliable supply of energy for lunar missions.

NASA has a Pretty Big Checklist for Boeing to Fix on Starliner

In 2014, NASA contracted two major aerospace companies (Boeing and SpaceX) to help them restore domestic launch capability to the United States. As part of the Commercial Crew Program (CCE), Boeing and SpaceX developed the CST-100 Starliner the Crew Dragon spacecraft, respectively. But whereas the Crew Dragon finished testing and even carried astronauts to the ISS, the Starliner met with some problems.

During its first uncrewed test flight – Orbital Flight Test-1 (OFT-1) – in December 2019, the Starliner experienced some failures that prevented it from docking with the ISS. After a thorough investigation, the joint NASA-Boeing Independent Review team has completed its final assessment and identified 80 areas where corrections need to be made before the Starliner can conduct another orbital flight test.

That’s So Metal. NASA’s Psyche Mission is Now Under Construction

In August of 2022, NASA will send a robotic spacecraft to the Main Asteroid Belt to explore a truly unique object: a metal asteroid. This object is known as 16 Psyche, is one of the largest asteroids in the Belt, and is composed almost entirely of iron and nickel. The most widely-accepted theory is that it used to be the core of a protoplanet in the Belt that experienced a massive collision that sent its rocky crust and mantle into space.

The spacecraft, also named Psyche, was submitted as part of a call for proposals for NASA’s Discovery Program in 2015 and was selected as the 14th Discovery mission by 2017. Most recently, the spacecraft passed a crucial milestone by moving from the planning and designing phase to the manufacturing phase, where all of the hardware that will allow it to make the journey is being assembled.

Although InSight’s Mole is Completely Buried, it Might be Stuck Again

You’ve gotta hand it to NASA, and to the German Aerospace Center (DLR.) They’ve been struggling for over a year to get the InSight Lander’s Mole working. There’ve been setbacks, then progress, then more setbacks, as they try to get the Mole deep enough to do its job.

Now the Mole is finally buried completely in the Martian surface, but it might still be stuck.

Help NASA Develop a Better Space Toilet

Right now, NASA is working towards its long-awaited return to the Moon. Known as Project Artemis, this program aims to send the “first woman and next man” to the lunar surface by 2024. Beyond that, NASA also plans to establish a “sustainable program of lunar exploration” with commercial and international partners. This means building the infrastructure that will allow people to stay on the Moon and facilitate eventual missions to Mars.

In order to meet this challenge, there are all kinds of questions that need to be addressed first. Besides the matter of how we can keep astronauts healthy during long-duration missions, there’s also the pressing question of how astronauts will relieve themselves on the Moon. Luckily for them, HeroX has launched the Lunar Loo Challenge – sponsored by the NASA Tournament Lab (NTL) – to come up with innovative new ideas!

A Simulation of Sunsets on Other Worlds: From Venus to Titan

When we think of exploring other planets and celestial bodies, we tend to focus on the big questions. How would astronauts live there when they’re not working? What kind of strategies and technology would be needed for people to be there long term? How might the gravity, environment, and radiation effect humans who choose to make places like the Moon, Mars, and other bodies place their home? We tend to overlook the simple stuff…

For example, what will it be like to look up at the sky? How will Earth, the stars, and any moon in orbit appear? And how will it look to watch the sun go down? These are things we take for granted here on Earth and don’t really ponder much. But thanks to NASA, we now have a tool that simulates what sunsets would look like from other bodies in the Solar System – from the hellish surface of Venus to the dense atmosphere of Uranus.

NASA Changes its Mind. It Will be Using Previously Flown Crew Dragons and Falcon 9

For the purpose of restoring domestic launch capability to US soil, NASA launched the Commercial Crew Program (CCP) in 2010. Alongside its commercial partners, Boeing and SpaceX, the focus of this program has been to develop crew-capable spacecraft that could deliver payloads and astronauts to the International Space Station (ISS), something NASA has been unable to do since the retirement of the Space Shuttle in 2011.

On May 30th, 2020, the CCP fulfilled its purpose as SpaceX’s Crew Dragon spacecraft was launched atop a Falcon 9 rocket and successfully delivered two astronauts (Robert Behnken and Douglas Hurley) to the ISS. Looking ahead, NASA and SpaceX have modified their contract agreement, which gives the company permission to use previously-flown Crew Dragon spacecraft and Falcon 9 boosters to send NASA astronauts to the ISS.
