NASA is funding research into advanced technology that would allow spacecraft to combine its propulsion system and the sun’s gravity to reach the distant Kuiper Belt or interstellar space in far less time than is possible today.
PASADENA, Calif. (NASA PR) — For the first time, a wayward comet-like object has been spotted near the family of ancient asteroids.
After traveling several billion miles toward the Sun, a wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way. The object has settled near a family of captured ancient asteroids, called Trojans, that are orbiting the Sun alongside Jupiter. This is the first time a comet-like object has been spotted near the Trojan population.
LOS ANGELES, Calif., Feb. 12, 2021 – Aerojet Rocketdyne recently received a contract award to deliver up to two Multi-Mission Radioisotope Thermoelectric Generators (MMRTG) to the U.S. Department of Energy (DOE) for use in future planetary science missions. MMRTGs are radioisotope power systems that have been used as reliable electrical power sources on multiple deep space missions, including NASA’s Perseverance Rover, which will land on Mars on Feb. 18.
PASADENA, Calif. (NASA PR) — When NASA’s Voyager 2 spacecraft flew by Neptune’s strange moon Triton three decades ago, it wrote a planetary science cliffhanger.
Voyager 2 is the only spacecraft ever to have flown past Neptune, and it left a lot of unanswered questions. The views were as stunning as they were puzzling, revealing massive, dark plumes of icy material spraying out from Triton‘s surface. But how? Images showed that the icy landscape was young and had been resurfaced over and over with fresh material. But what material, and from where?
NASA Advanced Innovative Concepts (NIAC) Phase I Award Amount: $125,000
Advanced Aerocapture System for Enabling Faster-Larger Planetary Science & Human Exploration Missions
Robert Moses NASA Langley Research Center
Aerocapture offers huge potential increases in science return by allowing the ability to deliver larger payloads, enabling faster transits of existing instruments, or offering flexibility to integrate payloads onto a single and perhaps cheaper launch vehicle. Previous calculations quantified the cost and delivered mass advantages of aerocapture for eleven representative missions for eight possible destinations in our solar system.
WASHINGTON (NASA PR) — NASA has selected four Discovery Program investigations to develop concept studies for new missions. Although they’re not official missions yet and some ultimately may not be chosen to move forward, the selections focus on compelling targets and science that are not covered by NASA’s active missions or recent selections. Final selections will be made next year.
The NASA Innovative Advanced Concepts (NIAC) program recently awarded 25 grants for the development of visionary new technologies. Here we’re going to take a closer look at the following three Phase II awards focused on new ways of exploring asteroids and moons.
Dismantling Rubble Pile Asteroids with AoES (Area-of-Effect Soft-bots) Jay McMahon University of Colorado, Boulder
Triton Hopper: Exploring Neptune’s Captured Kuiper Belt Object Steven Oleson NASA Glenn Research Center
NIMPH: Nano Icy Moons Propellant Harvester Michael VanWoerkom ExoTerra Resource
Each award is worth up to $500,000 for a two-year study. Descriptions of the awards are below. (more…)
WASHINGTON, DC (NASA PR) — NASA is investing in technology concepts that include meteoroid impact detection, space telescope swarms, and small orbital debris mapping technologies that may one day be used for future space exploration missions.
The agency selected 25 early-stage technology proposals that have the potential to transform future human and robotic exploration missions, introduce new exploration capabilities, and significantly improve current approaches to building and operating aerospace systems.
It’s going to be busy year in space in 2017. Here’s a look at what we can expect over the next 12 months.
A New Direction for NASA?
NASA’s focus under the Obama Administration has been to try to commercialize Earth orbit while creating a foundation that would allow the space agency to send astronauts to Mars in the 2030’s.
Whether Mars will remain a priority under the incoming Trump Administration remains to be seen. There is a possibility Trump will refocus the space agency on lunar missions instead.
Rep. Jim Bridenstine (R-OK), who is currently viewed as a leading candidate for NASA administrator, has written two blog posts focused on the importance of exploring the moon and developing its resources. Of course, whether Bridenstine will get NASA’s top job is unclear at this time.
Magnetoshell Aerocapture for Manned Missions and Planetary Deep Space Orbiters NASA Innovative Advance Concepts Phase II Award
David Kirtley MSNW, LLC
It is clear from past mission studies that a manned Mars mission, as well as deep space planetary orbiters will require aerobraking and aerocapture which use aerodynamic drag forces to slow the spacecraft. Aerocapture would enable long term studies of the outer planets and their moons that would not be possible with existing braking technologies. While utilizing planetary atmospheres to slow down and capture spacecraft would dramatically reduce the cost, launch mass, and travel time, current technologies require significant additional spacecraft mass and risk, as the spacecraft must descend deep into a planetary atmosphere that is not well characterized in order to produce significant drag on a relatively small, fixed dimension aeroshell or temperature and structurally sensitive inflatable ballute.
MOJAVE, Oct. 28, 2012 (IOS PR) —On a calm clear high-desert October evening, Interorbital Systems’ NEPTUNE rocket series’ main engine roared to life in its first hot-firing test.
The engine, the IOS GPRE 7.5KNTA (General Purpose Rocket Engine; 7,500lb-thrust; Nitric Acid; Turpentine; Ablative cooling), blasted a 22-foot (6.71-meter) plume of fire across Interorbital’s Mojave Spaceport test area, scorching the sand an additional 50 feet (15.24 meters) beyond the plume end.

“Inside the hangar the view is equally dramatic. A rocket, 30 feet long, lies on its side. Nearby sits a large capsule, looking like something out of the Apollo program. But this is the Neptune program – run not by NASA but by Roderick and Randa Milliron, a husband-and-wife rocketry company.
“The Neptune sure looks convincing. But will it fly?”
Welcome to Mojave, Calif., where “Will it fly?” is a constant question.
