SpaceX and Blue Origin’s Lunar Landers

SpaceX and Blue Origin have been busy building their own landers for the Artemis missions, which are NASA’s plans to return humans to the Moon. SpaceX’s Starship is designed to be a fully reusable spacecraft capable of landing astronauts on the Moon and taking them back to the Gateway orbiting the Moon. Meanwhile, Blue Origin is working on the Blue Moon lander, which will carry important supplies and equipment to the Moon’s surface. Both companies are pushing the limits of current space technology to make lunar missions cheaper, safer, and more sustainable. These landers are important pieces for getting us back on the Moon in the next few years.

NASA’s Lunar Rover

NASA is also designing a rover to transport astronauts on the Moon’s surface for their Artemis missions. The lunar rover will allow astronauts to travel across the lunar surface to explore and gather important scientific data. It’s being built to withstand the harsh conditions of the Moon, like extreme temperatures and rocky terrain. Companies have been asked to submit proposals to build this rover, which could even drive autonomously. The goal? To make sure astronauts can gather as much data as possible while being able to move around the Moon without limitations.

Orion Spacecraft

The Orion spacecraft is central to NASA’s Artemis program. It’s built to take astronauts from Earth to the Moon and, eventually, to Mars. In 2024, Orion has undergone multiple tests, simulating everything from deep space conditions to high-speed re-entry into Earth’s atmosphere. These tests are important for making sure the spacecraft can handle the challenges astronauts will face during their missions. Orion is equipped with life-support systems, emergency escape mechanisms, and communications equipment. Basically, it’s a high-tech survival pod ready to take astronauts on a journey like no other.

MAVEN Mission

The Mars Atmosphere and Volatile Evolution (MAVEN) mission has been studying the Martian atmosphere since 2014. As part of NASA’s long-term plan for Mars exploration, MAVEN provides critical data about how Mars lost its atmosphere and why the planet’s climate is so different from Earth’s. This information is important for future crewed missions to Mars because understanding the environment is needed for planning human survival on the Red Planet. MAVEN’s discoveries could help us figure out how to make Mars more habitable for humans one day.

Commercial Space Rocket

NASA has been increasingly involved with the commercial space industry. This includes enabling researchers to fly their payloads aboard commercial suborbital rockets. For instance, the first NASA-supported researcher had their payload launched into space with a commercial rocket. This is a big step in making space more accessible for research and experimentation. NASA has also been helping to develop technologies for small spacecraft, with the Starling demonstration being a major milestone. It showed that small groups of satellites could work together autonomously in space to share data. This is a main technology that could change how future space missions are managed, reducing the need for human intervention.

Fuel Gauge Technology and Cryogenic Propellant

NASA has also made breakthroughs in fuel measurement technology. On Intuitive Machines’ Nova-C lunar lander, they tested the Radio Frequency Mass Gauge, a technology that accurately measures spacecraft fuel levels. This is important for deep-space missions, where knowing how much fuel is left can be a matter of mission success or failure. NASA also conducted a major test with SpaceX’s Starship, transferring cryogenic propellants (liquid oxygen) in space, a major operation for fueling spacecraft in future deep-space missions.

3D Printing and Materials Development

Another area of focus is advanced materials. NASA has licensed a new 3D-printed superalloy, GRX-810, to four American companies. This material is stronger and more durable, ideal for use in parts of airplanes and spacecraft. NASA’s Rapid Analysis and Manufacturing Propulsion Technology project also achieved another milestone with 3D printing liquid oxygen/hydrogen thrust chamber hardware, which won NASA’s 2024 “Invention of the Year” award. This breakthrough is crucial for building more reliable and cost-effective propulsion systems for space exploration.

Quantum Physics in Space

NASA is pushing boundaries in quantum physics with the Cold Atom Lab. They have achieved groundbreaking results, like producing the first dual-species Bose-Einstein Condensates in space, and the first dual-species atom interferometers in space. These discoveries are important because they help scientists understand the fundamental laws of physics. The lab is also responsible for demonstrating the first ultra-cool quantum sensor in space. This could open up new ways of measuring gravitational waves and understanding dark matter.

Mk-II Aurora Rocket-Powered Aircraft

Unlike regular rockets, Dawn Aerospace’s Mk-II Aurora combines rocket power with the reusability of an aircraft. This means it can take off from normal runways and potentially fly several times a day, cutting down costs for space missions. It’s still in testing, but it has huge potential for things like Earth observation, scientific research, and microgravity experiments. The fact that it doesn’t need specialized spaceports and can operate from regular airports could make space launches much faster and more affordable.

X-59 Quiet Supersonic Transport

The X-59 is NASA’s and Lockheed Martin’s effort to bring back supersonic flying, but without the loud sonic booms. Regular supersonic jets, like the Concorde, weren’t allowed to fly over land because of the noise, but the X-59 has been designed to make a soft “thump” instead of a boom. If all goes well, this could let supersonic travel become normal again, cutting flight times while keeping noise levels down. NASA is set to begin test flights in 2025, and they’ll even ask the public for feedback on how the new design impacts noise.

Polaris Dawn Spacewalk by SpaceX

In September 2024, SpaceX made history with the first-ever private spacewalk during the Polaris Dawn mission. Until now, spacewalks have been done by government space agencies, but this mission shows that private companies can do it too. The astronauts wore SpaceX’s new spacewalk suits, which performed well during the test. This is a big step toward making spacewalks available for commercial missions in the future. It could open up more opportunities for private individuals or companies to take part in these experiences.

Europa Clipper

NASA launched the Europa Clipper mission in October 2024 to explore Jupiter’s moon Europa, which scientists believe could have the right conditions for life. Europa has an ocean beneath its icy surface, and the mission will search for signs of water vapor plumes and gather data to better understand what’s underneath. It will also map the surface in incredible detail. The spacecraft won’t arrive at Europa until 2031, but this mission could provide clues about whether life could exist beyond Earth, and it may pave the way for future missions aimed at answering that question.
