Mission To Mars 2049

[Christain Cobb]

Thenew recommendation comes from a process called the decadal survey, which is led by the National Academy of Sciences and offers NASA guidance for prioritizing science goals. That committee's new report, published Tuesday (April 19), highlighted a mission concept called the Uranus Orbiter and Probe (UOP) for a multi-year orbital tour during which it should jettison an atmospheric probe. The committee called Uranus "one of the most intriguing bodies in the solar system" and targeted launch opportunities in the early 2030s for a 12- to 13-year cruise out to begin observations.

"When I first read that recommendation, I feared I might be dreaming!" Leigh Fletcher, a planetary scientist at the University of Leicester in the U.K. who participated in the decadal survey process, told Space.com. "This decadal survey prioritization is a wonderful leap forward for the outer solar system community."

For now, the Uranus Orbiter and Probe isn't a specific mission, but a concept. The previous decadal survey, released in 2011, mentioned the idea as the third priority for a flagship mission, following ideas that matured into the Perseverance rover now at work on Mars and the Europa Clipper mission due to launch in 2024.

Other reports have also stressed the need for a fully-equipped Uranus orbiter, complete with an atmospheric probe to dive beneath the planet's clouds. The pre-Decadal Survey Ice Giants study report included a variety of options for Uranus and Neptune spacecraft, while a white paper called Exploration of the Ice Giant Systems also submitted to the decadal survey committee discusses the need for an orbiter/probe combo in a flagship-class mission.

Lead author of the latter ice giants report is Chloe Beddingfield, a planetary scientist and astronomer at NASA'sAmes Research Center in California, who thinks that there's compelling broad planetary and even exoplanet science to be done at Uranus. "A flagship mission to the Uranian system will provide an incredible opportunity to explore how ice giant systems, which are common in the galaxy, formed and evolved," she told Space.com. That crossover with exoplanet science may have helped Uranus' cause.

The Uranus Orbiter and Probe mission will cost in the region of $4.2 billion, according to initial evaluations. Some scientists thought that a more affordable concept costing under $900 million would be the only way to get a Uranus mission off the ground. (NASA calls missions of this budget "New Frontiers" missions; examples include the Juno mission to Jupiter and the OSIRIS-REx mission to fetch an asteroid sample.)

"To fully explore Uranus we need to be in orbit, exploring the interior, atmosphere and magnetosphere, and touring the myriad icy moons and rings," he added. "If it's worth doing, then it's worth doing properly!"

How long it will take to reach Uranus depends on when a spacecraft launches. A gravity-assist from Jupiter is required for a larger spacecraft to avoid an unduly long journey. The giant planet's position means a Uranus mission would preferably launch in 2031 or 2032 to arrive at Uranus in 2044 or 2045. It could leave Earth as late as 2038, but that would mean a 15-year journey.

However, there's a good scientific reason to get to Uranus by 2045. A year on Uranus lasts 84 Earth years and Voyager 2 flew past during the southern hemisphere's summer, so if scientists want the most contrast with that mission's views then the new spacecraft needs to arrive before southern spring begins in 2049.

"Uranus' large moons are really weird," Richard Cartwright, a planetary scientist and astronomer at NASA's Ames Research Center and lead author of a paper proposing a Uranus Orbiter, told Space.com. He noted that Voyager 2's brief flyby captured snapshots of the moons' surfaces that showevidence for geologic activity on Miranda and Ariel in particular.

"However, the northern hemispheres of the Uranian moons were shrouded by winter darkness at the time of the flyby and were largely unimaged, leaving many unanswered questions about the origin and evolution of these icy bodies," he said. For now, Cartwright has arranged to use the recently-launched James Webb Space Telescope to search for chemicals that may have leaked out of internal oceans on these worlds, but that's no comparison to visiting up close.

"A good possible name for the orbiter is 'Caelus,' which is the Roman counterpart of the Greek god Uranus," Beddingfield offered. "This would be fitting because Uranus is the only planet in our solar sSystem named after a character from Greek instead of Roman mythology."

Another option could be "Shakespeare" for the Uranus orbiter and "Pope" for the atmospheric probe. After all, the moons of Uranus are named after characters from the works of William Shakespeare and the British poet Alexander Pope. For example, Ariel and Miranda feature in Shakespeare's "The Tempest" while Titania and Oberon are from his "A Midsummer Night's Dream."

Mission to Mars 2049 is a strategic family board game in which players build and manage their colonies on Mars in a race to reach the planet's North Pole. Gameplay You start with a single base on the outside of the map and gradually expand your colony one base at a time until you reach the Martian North Pole. The player who builds the water extraction station on the center of the map first, wins the game. Mission cards To add extra strategies to the game, there are mission cards. Peaceful mission cards will allow you to be GOOD and play by using only your own resources while the aggressive mission cards will let you be BAD and attack other players' posessions.

Neptune Odyssey is an orbiter mission concept to study Neptune and its moons, particularly Triton.[1] The orbiter would enter into a retrograde orbit of Neptune to facilitate simultaneous study of Triton and would launch an atmospheric probe to characterize Neptune's atmosphere. The concept is being developed as a potential large strategic science mission for NASA by a team led by the Applied Physics Laboratory at Johns Hopkins University. The current proposal targets a launch in 2033 using the Space Launch System with arrival at Neptune in 2049, although trajectories using gravity assists at Jupiter have also been considered with launch dates in 2031.

Two flyby mission proposals for Neptune and Triton also exist, both of which would conduct a flyby in 2038. The China National Space Administration's Interstellar Express, a trio of probes designed to explore the heliosphere, would have its second probe (IHP-2) explore Neptune and deliver an atmospheric probe before going off to explore a Kuiper Belt object and fly toward the tail of the heliosphere. NASA's Trident was a finalist for selection as a Discovery mission in 2020, with a proposed launch in 2025 and an intent to focus on Triton.[14] In June 2021, it was announced that Trident was not selected for development and launch,[15] while Interstellar Express is yet to be approved by CNSA.

The present proposal targets a launch in 2033 using the Space Launch System and a 16-year cruise directly to Neptune, with launch windows yearly during the 2030s. The cruise could be shortened to 12 years with a gravity assist at Jupiter, but this would require launch prior to 2032. A 220 kg (490 lb) atmospheric probe will be released from the orbiter before orbital insertion at Neptune and descend for around 37 minutes into Neptune's atmosphere to study its composition, dynamics, and processes, sending data at least until reaching a pressure of 10 bars. After achieving Neptune orbit, the orbiter will conduct at least 46 flybys of Triton over the four-year main science phase, achieving near-global coverage of the moon while simultaneously studying Neptune and other moons. The orbiter would then orbit progressively closer to Neptune and its rings on a "Grand Finale" similar to the Grand Finale of Cassini and eventually be destroyed in Neptune's atmosphere for planetary protection purposes.
