In a study published today in the Astrophysical Journal Letters, scientists from the University of New Hampshire and colleagues answer the question of why NASA’s Voyager 1, when it became the first probe to enter interstellar space in mid-2012, observed a magnetic field that was inconsistent with that derived from other spacecraft observations.
Voyager 1 sent back several different indications that it had punched through the edge of our sun’s massive protective bubble inflated by solar wind—the heliosphere—after a 35-year journey. But the magnetic field data gathered by the spacecraft was not what scientists had expected to see. The UNH-led study resolves the inconsistencies.
“There are still naysayers out there regarding Voyager 1 crossing through the heliopause—the edge of the heliosphere,” says astrophysicist Nathan Schwadron of the UNH Institute for the Study of Earth, Oceans, and Space and department of physics and lead author of the paper. “And the reason for this doubt is that when the spacecraft supposedly broke through the heliopause we should have seen some sort of distinctive shift in the magnetic field from one medium to the other,” Schwadron says.
The novel its a bit older, but it‘s an incredible vision!
When Star Trek’s Scotty warns the Captain that the engines can’t “take it”, he might just be best off switching fuel — a new book claims that humanity could reach the stars using vast spacecraft harnessing the energy of black holes with the power to “eat planets”.
The Russian Federal Space Agency — commonly referred to as Roscosmos — just announced its plans to send humans to the Moon in 2029, RT News reported. It’s part of the agency’s ultimate goal of creating and maintaining a lunar station. Vladimir Solntsev, head of Roscomsos Energia, made the announcement Tuesday at a space and technology conference in Moscow; he noted that they are currently building the spacecraft for the mission now, with its first flight into space planned for 2021.
After its initial flight, the plan is to have the spacecraft dock with the International Space Station in 2023, according to Solntsev. Then in 2025, Roscosmos will send an uncrewed version of the spacecraft to the Moon, before finally sending astronauts in the vehicle in 2029.
It also looks like the European Space Agency may be along for the ride. Two weeks ago, BBC News reported that the ESA had been in talks with Roscosmos to collaborate on sending a lander to the Moon’s south pole. The mission, called Luna 27, would be the first in a series of missions that would eventually return humans to the lunar surface. “We have an ambition to have European astronauts on the Moon. There are currently discussions at international level going on for broad cooperation on how to go back to the Moon,” Bérengère Houdou, head of lunar exploration at ESA, told BBC News.
A Hall thruster is powering many of the satellites moving around Earth right now. It needs 100 million (yes, you read that right, 100 million) times less fuel than chemical thrusters. But it was never remotely sturdy enough to get anything to Mars—until now.
Typical chemical thrusters are pretty simple. Fuel combusts, gases shoot one way, and a rocket shoots the other way.
Ion thrusters are a little different. They contain charged electrodes, an anode and a cathode, and allow positively charged ions to shoot from the anode to the cathode. Thanks to momentum, the ions will “overshoot” the cathode. Under regular circumstances they’d be sucked back, but once they’ve cleared the cathode, they’re hit by a beam of electrons, neutralizing them and allowing them to go on their way without interference from the charged cathode. So the neutralized atoms shoot one way, and the rocket shoots another.
“Wolf went for a walk over the world from the Mir Space Station in the late 1990s and saw the Earth seemingly vanish. His recollection so moved New York-based artist Rachel Rose when she heard it on NPR that she went to considerable lengths to track him down for a personal retelling.”
Photographs taken by astronaut Scott Kelly from the International Space Station are beautiful – but could a robot do better?
