For Nuclear-Thermal Propulsion (NTP), the cycle consists of a nuclear reactor heating liquid hydrogen (LH 2) propellant, turning it into ionized hydrogen gas (plasma) that is then channeled through nozzles to generate thrust. Nuclear propulsion essentially comes down to two concepts, both of which rely on technologies that have been thoroughly tested and validated. Other proposals included innovative sensors, instruments, manufacturing techniques, power systems, and more. Gosse’s proposal is one of 14 selected by the NIAC this year for Phase I development, which includes a $12,500 grant to assist in maturing the technology and methods involved. Ryan Gosse, the Hypersonics Program Area Lead at the University of Florida and a member of the Florida Applied Research in Engineering (FLARE) team. The proposal, titled “ Bimodal NTP/NEP with a Wave Rotor Topping Cycle,” was put forward by Prof. This new class of bimodal nuclear propulsion system uses a “ wave rotor topping cycle” and could reduce transit times to Mars to just 45 days. As part of the NASA Innovative Advanced Concepts (NIAC) program for 2023, NASA selected a nuclear concept for Phase I development. A few years ago, NASA reignited its nuclear program for the purpose of developing bimodal nuclear propulsion – a two-part system consisting of an NTP and NEP element – that could enable transits to Mars in 100 days. NASA and the Soviet space program spent decades researching nuclear propulsion during the Space Race. And when it comes to the latter, Nuclear Thermal and Nuclear Electric Propulsion (NTP/NEP) is a top contender! These and other missions that will take astronauts beyond Low Earth Orbit (LEO) and the Earth-Moon system require new technologies, ranging from life support and radiation shielding to power and propulsion. This will be followed in the next decade with crewed missions to Mars by NASA and China, who may be joined by other nations before long. Analysts say this is unsustainable and note it is already billions of dollars over budget and years behind schedule.We live in an era of renewed space exploration, where multiple agencies are planning to send astronauts to the Moon in the coming years. The Artemis program comes with a $93bn price tag, including $4.1bn for each of the first launches. Nasa administrator, Bill Nelson, explained the purpose of the Artemis program in an interview with Newsweek earlier this year: “We’re going back to the moon after 50 years, to stay, to learn, to work, to create, to develop new technologies and new systems and new spacecraft in order to go to Mars … This is a tremendous turn of history.” Hopes of an early October launch were thwarted when the threat of Hurricane Ian forced the space agency to roll the giant $4.1bn Space Launch System (SLS) rocket back to the safety of the hangar. ![]() The “crew” for Artemis 1 includes sensor-rigged mannequins called Helga, Zohar and Moonikin Campos, who will gauge radiation levels, and a soft toy Snoopy and Shaun the Sheep as gravity detectors.Ī series of delays through the summer and early fall held the launch date back after attempts in August and September were scrapped when engineers discovered an engine cooling problem, then were unable to fix an unrelated fuel leak. The Orion capsule is set for a 25-day, 1.3m-mile journey to the moon and back. If you have just joined us, here’s what we know so far: The test flight aims to send an empty crew capsule into a far-flung lunar orbit, 50 years after Nasa’s famed Apollo moonshots.įor any updates or feedback you wish to share, please feel free to get in touch via email or Twitter. ![]() The launch is part of Nasa’s new moon program with a test flight of a brand-new rocket and capsule. The Artemis 1, the most powerful rocket ship in history, will launch from Cape Canaveral, Florida, at 1.04am EST (6.04am GMT) on Wednesday. ![]() I’m Samantha Lock and I’ll be bringing you all the latest developments as they unfold over the next couple of hours. Hello and welcome to the Guardian’s live coverage of Nasa’s Artemis rocket launch to the moon. 06.39 GMT Nasa kicks off new moon program
